Uncovering a hidden danger: a case report of diffuse coronary spasm concealing spontaneous coronary artery dissection

BackgroundOver recent years, spontaneous coronary artery dissection (SCAD) has emerged as a no longer rare cause of acute coronary syndrome (ACS). On the other hand, coronary artery spasm (CAS) is the main cause of ischemic heart disease with non-obstructive coronary lesions. Clinical manifestations of both vary from stable angina to ACS or, rarely, sudden cardiac death. These entities may be underdiagnosed on a coronary angiography.Case presentationWe report the case of a young woman presenting with acute chest pain and no coronary risk factors. Angiography revealed a focal subcritical stenosis of the right coronary artery. Coronary wiring resulted in diffuse and critical spasm. However, optical coherence tomography (OCT) and intravascular ultrasound (IVUS) showed extensive SCAD. She was therefore treated conservatively. On the fourth day, cardiac computed tomography angiography (CCTA) excluded disease progression, and then she was discharged on medical therapy.ConclusionsCombined IVI plays a vital role in providing accurate and detailed visualization of the coronary anatomy and thus allowing for more precise diagnosis, risk stratification, and treatment planning. CCTA can be considered a valuable tool in the noninvasive follow-up of SCAD.

Abstract 12525: Acute Pulmonary Edema, Mid-Ventricular Stress Cardiomyopathy and Cardiogenic Shock Following Intranasal Lidocaine/Epinephrine Administration During Septorhinoplasty

Case Presentation: A 19-year-old female presented for elective septorhinoplasty for nasal septal deviation and turbinate hypertrophy. After induction of anesthesia, and orotracheal intubation, pledgets soaked in 4% topical lidocaine with 1:1,000 epinephrine were placed in bilateral nares. Next, 1% lidocaine with 1:100,000 epinephrine was locally injected in the nasal mucosa to obtain hemostasis and analgesia. This resulted in transient hypertensive emergency, followed by undifferentiated shock requiring the initiation of norepinephrine. No signs of ischemia were seen on EKG. Chest X-ray revealed acute pulmonary edema. TTE showed reduced left ventricular systolic function, EF 30%, with mid-segment akinesis, consistent with mid-ventricular stress cardiomyopathy. Coronary angiography identified normal anatomy and patent arteries, supporting the diagnosis. Surveillance TTE after extubation and empiric treatment with metoprolol and losartan, showed improvement of EF to 45-50% and resolution of regional wall motion abnormalities. Discussion: Stress cardiomyopathy, also known as Takotsubo (TCM), is a rare form of cardiomyopathy accounting for 2-3% of ACS. The syndrome mainly affects the LV, causing a regional, transient, systolic dysfunction visualized on TTE or left ventriculography, that occurs in the absence of obstructive epicardial coronary lesions. Pathogenesis is poorly understood. Postulated mechanisms include catecholamine excess, coronary artery spasm and microvascular dysfunction. A systematic review found elevated norepinephrine levels in 74.3% of patients diagnosed with TCM, as was the case for our patient. Rapid systemic absorption of epinephrine can cause diffuse microvascular spasm and myocardial stunning. Catecholamine surge may also afflict direct myocardial toxicity, leading to disorganized cytoskeletal structures, excess extracellular matrix proteins and dysfunctional contractile properties of the myocardium.

Coronary Spasm: Ethnic and Sex Differences.

Coronary spasm (CS), which may occur at the epicardial (focal or diffuse spasm) and/or microvascular (microvascular spasm) level, is a well-established cause of myocardial ischaemia, in particular in patients with anginal chest pain despite unobstructed coronary arteries. The diagnosis of CS can be confirmed during coronary angiography by an additional provocation test with vasoactive substances such as acetylcholine. Due to partially inconsistent data from large clinical studies, especially between Asian and white CS patients, ethnic differences concerning the prevalence and angiographic patterns of CS seem to exist. Furthermore, several studies in patients with coronary vasomotor disorders pointed towards differences among male and female CS patients. This article gives an overview of ethnic- and sex-related differences in patients with CS.

P34 TAKOTSUBO SYNDROME OR UNKNOWN MYOCARDIAL ISCHEMIA? THE ROLE OF CARDIAC MAGNETIC RESONANCE IN DIFFERENTIAL DIAGNOSIS

Abstract There are numerous clinical conditions in which symptoms and signs may overlap, among these myocardial Ischemia in the absence of obstructive coronaropathy (INOCA/MINOCA), gets into differential diagnosis with a plethora of clinical pictures such as Takotsubo syndrome, myocarditis and cardiomyopathies. In this setting, cardiac magnetic resonance has a critical discriminating role. Herein we report the clinical case of a 52–year old patient suffering from hypertension and dyslipidaemia, with a history of chest pain episodes and recent intense psychophysical stress. After symptoms exacerbation, ambulance was called, loss of conscience was witnessed, observing ventricular fibrillation, subjected to prompt DC shock. Once in Emergency room, ECG showed ST–elevation in V1, V2 and AVR for which urgent coronary angiography was performed. It surprisingly resulted negative for epicardial coronary artery disease. Moderate left ventricular dysfunction (LVEF 45%) was found on 2D ultrasound along with apex akinesia, while mild elevation myocardial necrosis enzymes was seen at blood tests. The clinical picture characterized by female sex, history of psychophysical stress, by association of chest pain, ischemic type alterations of repolarization at ECG, akinesia of the apex and the concomitant slight elevation of myocardial necrosis enzymes in the absence of epicardial coronary lesions, highly suggested Tako–Tsubo Syndrome. In order to confirm the diagnosis, cardiac MRI was performed which, unexpectedly, showed the presence of oedema on T2–weighted STIR sequences at the level of the left ventricular apex, associated to same site transmural fibrosis at post–contrast imaging sequences, thus eliciting the hypothesis of a MINOCA. After a new retrosternal pain with transient ST–elevation in V1, a IVUS – guided new coronary angiography examination was performed, resulting intoIVA diffuse coronary spasm, reduced after intravenous nitrate administration. Final diagnosis was “MINOCA complicated by primary VF‘‘ and a subcutaneous AICD implant CMR imaging by virtue of its ability to provide information about cardiac structure and function and simultaneously, to define the characterization of tissues, together with the data of dynamic coronary spasm, proved to be essential in this case to establish the diagnosis, often misunderstood, of MINOCA, hence allowing to define the best therapeutic strategy. ​

P475 RECURRENT CORONARY ARTERY VASOSPASM COMPLICATED BY CARDIAC ARRESTS IN HEART TRANSPLANT RECIPIENT: AN UNUSUAL ENEMY

Abstract Even if coronary vasospasm (CV) is considered a rare phenomenon in heart transplant (HT) recipients, during routine coronary angiography asymptomatic CV may be observed. We report the case of a 30–year–old male who underwent HT in 2007 for dilatative cardiomyopathy. He was maintained on tacrolimus and mycophenolate mofetil and had no significant rejection or coronary allograft vasculopathy (CAV) demonstration. In December 2020 patient presented with cardiac arrest preceded by angina. Coronary angiography demonstrated diffuse spasm of the right coronary artery (RCA) with resolution after intracoronary nitrate administration. An endomyocardial biopsy (EBM) revealed no signs of cellular rejection whilst cardiac magnetic resonance showed signs of acute rejection (Fig.1). Moreover, two major histocompatibility complex (MHC) Class 2 donor–specific antibodies (DSAs) were positive with a high title. Treatment for antibody–mediated rejection (AMR) was initiated with steroids and plasmapheresis, followed by immunoglobulin infusion. Cardiac defibrillator was implanted before discharge. In August 2021, patient experienced a second cardiac arrest. Left heart catheterization found diffuse CV and after nitrates administration, proximal critical stenosis of RCA was pointed out and treated with stent insertion (Fig. 2–3). EMB and DSAs assessment were both negative. The patient was discharged after medical therapy optimization for CV prevention including the switch from mycophenolate to everolimus. After two more episodes of ACS with angiography finding of CV we decided to empirically treat the patient with weekly photopheresis sessions. Despite aggressive AMR management, a third ACC occurred in March 2022. The patient was finally reintroduced to the HT waiting list. Most CV episodes run without any symptoms due to the denervated heart post–transplant so probably re–innervation occurred in our patient. Calcium channel blockers, nitrates, and beta–blockers failed in CV prevention, suggesting ineffectiveness in HT recipients because of a different pathogenetic mechanism when compared to healthy subjects. Furthermore, documentation of coronary disease progression after the second ACC supports the hypothesis that CV could be the first manifestation of CAV. An intriguing hypothesis would be the presence of pathological vasoreactivity in the donor‘s heart, ascribable to an “inherited” endothelial dysfunction that could last be exacerbated by multiple factors, including AMR.

Diffuse refractory coronary artery spasm after off-pump coronary artery bypass grafting: a case series

BackgroundDiffuse coronary artery spasm after coronary artery bypass grafting may cause disastrous circulatory collapse and death if not detected and managed promptly.Case presentationFour out of 387 patients who underwent uneventful off-pump coronary artery bypass grafting between January 2019 and December 2021 at our centre developed unexplained arrhythmias and hypotension within 2 to 6 h of the postoperative period. Coronary angiogram showed diffuse coronary vasospasm involving both grafted and ungrafted native coronary arteries. Vasospasm was refractory to intracoronary vasodilators in all these cases. All of the patients recovered completely with the use of intravenous verapamil infusion and intraaortic balloon pump support.ConclusionsCoronary artery spasm should remain in the differential diagnosis in patients developing unexplained arrhythmias and haemodynamic instability following coronary artery bypass grafting. Prompt diagnosis with coronary angiogram and proper management strategy using calcium channel blockers and intraaortic balloon pump can revert this deadly complication. Surgical intervention may delay precious time needed for therapeutic intervention.

Resuscitated sudden cardiac arrest related to intraplaque haemorrhage and coronary artery spasm.

A 72-year-old man with a history of chronic kidney disease, dyslipidaemia, and hypertension felt chest tightness after walking uphill and sat down to rest. Shortly thereafter, he suddenly collapsed, and cardiopulmonary resuscitation was started by a nearby family member. The initial electrocardiogram waveform was ventricular fibrillation, which was restored to sinus rhythm with an automated external defibrillator. He was transported to our hospital. No significant electrocardiographic changes, but positive serum troponin was observed on arrival. Emergency coronary angiography was performed, revealing a moderate stenosis in the proximal left anterior descending coronary artery (Panel A) which was functionally significant (Panel B). Optical coherence tomography showed a large eccentric plaque with a confined low-intensity plaque with strong signal attenuation (Panel C) and some areas of low intensity and low attenuation (Panel D), highly suggestive of intraplaque haemorrhage (IPH) (see Supplementary data online, Video S1).1 A stent implantation was subsequently performed (Panel E). On the ninth day of hospitalization, an acetylcholine provocation test was performed for the right coronary artery and severe diffuse coronary spasm was induced (Panels F and G) accompanied by chest tightness and ST elevation on electrocardiogram, leading to a diagnosis of coronary spastic angina.

Does the intracoronary pressure differ according to two types (diffuse or focal) of coronary spasm?

Several reports show that two types of coronary vasospasm (diffuse and focal spasm) are associated with the severity or prognosis of coronary spasm in patients with vasospastic angina (VSA). It is unclear whether intracoronary pressure differs between the two spasm types. To investigate such relationships using a pressure wire during the spasm provocation test (SPT) in patients with VSA. Eighty-seven patients with VSA (average age: 67 years; 50 men, 37 women) underwent SPT. During the SPT, a pressure wire was advanced into the distal portion of the right coronary artery and left anterior descending coronary artery, and the ratio of the intracoronary pressure to the aortic pressure (Pd/Pa) was continuously monitored. An SPT was performed using acetylcholine (ACh), and the presence of coronary spasm was defined as the presence of > 90% arterial narrowing in response to an ACh infusion, with the usual chest symptoms and/or ischemic ECG changes. Focal spasm was defined as total or subtotal spasm within one segment of the AHA classification, while diffuse spasm was defined as > 90% spasm with two or more segments. Among 87 patients, the frequencies of metabolic syndrome and having coronary atherosclerosis were higher in the focal group (n = 33) than in the diffuse spasm group (n = 54, P < 0.05). In the vessel analyses, in these 134 spastic segments, diffuse and focal spasms were detected in 100 and 34 vessels, respectively. The Pd/Pa at baseline was similar in both groups (diffuse: 0.96 ± 0.05, focal: 0.95 ± 0.05, P = 0.35); however, the Pd/Pa during coronary spasm was lower in focal spastic vessels (0.66 ± 0.20) than in diffuse spastic vessels (0.76 ± 0.11, P < 0.01), and the reduction in Pd/Pa during an SPT was also lower in focal spastic vessels (-0.29 ± 0.20) than in diffuse spastic vessels (-0.18 ± 0.11, P < 0.01). The presence of focal spasm was a significant factor responsible for reduction in Pd/Pa during SPT. These findings suggest that focal spasm may be more severe than diffuse spasm, judging from the intracoronary pressure during coronary spasm.

Refractory diffuse coronary artery spasm post aortic valve replacement

Postoperative coronary artery spasm occurs rarely after valve replacement surgery. We report the case of a 64-year-old man with normal coronary arteries who underwent aortic valve replacement. Nineteen hours postoperatively, his blood pressure plummeted with an elevated ST-segment. Coronary angiography demonstrated a 3-vessel diffuse coronary artery spasm, and direct intracoronary infusion therapy was performed with isosorbide nitrate, nicorandil and sodium nitroprusside hydrate within 1 h of onset. Nonetheless, there was no improvement, and the patient was resistant to treatment. The patient died due to prolonged low cardiac function and pneumonia complications. Prompt intracoronary vasodilator infusion is considered effective. However, this case was refractory to multi-drug intracoronary infusion therapy and was not salvageable.

239 VASOSPASTIC ANGINA: A CASE OF COMPLETE FUNCTIONAL ASSESSMENT

Abstract Introduction Vasospastic angina is defined as a focal or diffuse spasm of the arterial wall of an epicardial coronary artery due to muscle cells hyperreactivity caused by an increased calcium sensitivity. Clinical presentation typically consists in chronic story of rest and/or effort typical chest pain, episodes of ST elevated or not ST elevated myocardial infarction, arrhythmias or cardiac arrest; an increased vagal tone, drugs, allergic reactions or the exposure to extreme cold also can trigger vasospasm. Clinical case 73 years old dyslipidemic woman; in past medical history thyroidectomy and radiotherapy for carcinoma and right quadrantectomy with radiotherapy and hormonal therapy for breast cancer. In 2017 admission to cath-lab for non-ST elevation myocardial infarction (NSTEMI) with the evidence of mild left coronary artery disease without critical obstructive stenosis (MINOCA). For the persisting of effort angina and dyspnea (NYHA and CCS II-III), started Diltiazem therapy (60 mg x3) with clinical benefit. In 2020, due to the onset of new episodes of angina, started Ranolazine therapy. In June 2022, for the worsening of clinical symptoms, was evaluated with a Coronary CT, that showed a 65% stenosis at right coronary-acute marginal bifurcation and mild disease on left coronary artery, and then was admitted for an elective coronary angiography, with no evidence of epicardial artery critical stenosis. At the functional evaluation FFR, CFR and IMR (&amp;gt;0.80, 2.5 and 18) demonstrated normal coronary flow reserve and good microcirculation function. For the suspicion of vasospastic angina, acetylcholine test was performed with the evidence of mid-distal left anterior descending artery total occlusion, angina onset and ECG changes, promptly regressed with nitrates administration (Figure 1). Patient was discharged with the optimization of medical therapy with Diltiazem 120 mg x3, with clinical benefit. Conclusions To date vasospastic angina remains underdiagnosed. Functional evaluation of coronary arteries plays a fundamental role in the diagnostic algorithm of the disease and should always be investigated in case of patients with typical symptoms and the absence of critical epicardial stenosis. Further investigations are required to better explain pathogenesis and to identify affected patients in shorter times to ensure early optimized medical therapy.

Abstract 12018: Coronary Microvascular Dilatory Dysfunction According to the Types of Coronary Functional Abnormalitiescoronarymicrovascular Dilatory Dysfunction According to the Types of Coronary Functional Abnormalities

Introduction: Recently, there has been an increasing interest in coronary functional abnormalities (CFA), which include epicardial coronary spasm (ECS), microvascular spasm (MVS) and microvascular vasodilatory dysfunction (MVD). However, the frequency of MVD according to the types of CFA remains unclear. Hypothesis: Thus, this study aimed to investigate the frequency of MVD according to the types of CFA in patients with ischemia with non-obstructive coronary arteries (INOCA). Methods: This study included 63 patients with INOCA who underwent coronary angiography (CAG) and coronary function tests (CFT) to evaluate chest pain. In CFT, acetylcholine was first administered intracoronarily in a stepwise manner, followed by chest symptoms, electrocardiographic ST-T changes and CAG. ECS was defined as coronary vasoconstriction of &gt;90% on CAG accompanied by chest symptoms or electrocardiographic ST-T changes. Additionally, a focal spasm was defined as a transient vessel narrowing of &gt;90% within the borders of one isolated coronary segment (as defined by the American Heart Association), and a diffuse spasm was defined as a 90% diffuse vasoconstriction in ≥2 adjacent coronary segments of the coronary artery. Moreover, MVS was defined as the presence of both chest symptoms and ST-T changes with non-significant coronary vasoconstriction (&lt;90%) on CAG. After nitroglycerin administration, coronary flow reserve (CFR) and the index of microcirculatory resistance (IMR) were subsequently obtained by transvenous adenosine triphosphate infusion using a pressure wire. MVD was defined as CFR of &lt;2.0 or IMR of ≥25 units. Results: CAG and CFT were performed on 91 coronary arteries in 63 patients with INOCA, the results of which are shown below. Conclusions: These findings suggest that the frequency of MVD differs according to the types of CFA. Properly evaluating the MVD and reflecting this in the therapeutic strategy in patients with INOCA is desirable in clinical settings.

Clinical Outcomes and Provoked Epicardial Spasm Phenotypes via Intracoronary Acetylcholine Testing in 680 Patients with Angina and Nonobstructive Coronary Arteries.

Background: Epicardial spasm (ES) phenotypes may be related to the prognosis in patients with coronary spastic angina. Objectives: The purpose of this study was to elucidate the relationship between angiographic coronary vasomotor responses to intracoronary acetylcholine (ACh) injection and prognosis in patients with angina and nonobstructive coronary artery disease (ANOCAD). Methods: This was a retrospective, observational, single-center study of 680 patients with ANOCAD. ACh spasm provocation tests on both coronary arteries were performed without administering nitroglycerine to relieve provoked spasm in a first-attempt artery. ACh was injected in incremental doses of 20/50/100/200 μg into the left coronary artery and 20/50/80 μg into the right coronary artery. Positive ES was defined as ≥90% stenosis and usual chest pain and ischemic ECG changes. Results: Provoked positive ES was observed in 310 patients (46%), including 85 patients (13%) with focal spasm, 150 patients (22%) with diffuse spasm, and 75 patients (11%) with combined spasm (diffuse spasm and focal spasm), whereas the remaining 370 patients (54%) had no provoked spasm. An unclassified ACh test was observed in 186 patients (27%), while 184 patients (27%) had a complete negative ACh test. The clinical outcomes in patients with complete negative ES were satisfactory compared with those with positive ES and unclassified ACh test results. The prognosis in patients with an unclassified ACh test was not different from those with a positive ES. Furthermore, prognosis in patients with ES phenotypes was not different among the three groups. Conclusions: There was no correlation between provoked ES phenotypes via intracoronary ACh testing and prognosis in patients with ANOCAD; however, clinical outcomes in patients with positive ES and unclassified ACh tests were worse compared to those with complete negative ACh tests. We should focus on the treatments in patients with unclassified ACh tests as well as those with ESs.

Successful Treatment of Whole Coronary Artery Spasm after Off-Pump Coronary Artery Bypass Grafting

Coronary artery spasm after coronary artery bypass grafting is a rare but life-threatening condition. Herein, we report the case of a 77-year-old man who received off-pump coronary artery bypass grafting. An hour after surgery, there was a sudden hemodynamic compromise due to coronary artery spasm, prompting emergent coronary angiography with extracorporeal membrane oxygenation support. Because the angiography results showed diffuse severe spasm of the entire native coronary artery, the patient was treated with an intracoronary injection of vasodilators. The patient recovered in 7 days with mechanical support, catecholamines, and vasodilators, and he was discharged on postoperative day 30. Although coronary artery spasm after off-pump coronary artery bypass surgery is a rare condition, it must be suspected when sudden circulatory collapse occurs.

Assessment of coronary spasms with transluminal attenuation gradient in coronary computed tomography angiography.

To evaluate the imaging features of coronary spasm, including transluminal attenuation gradient (TAG) on coronary computed tomography angiography (CCTA), in patients with vasospastic angina (VA). A total of 43 patients with a high clinical likelihood of VA were included in the study. All the subjects underwent double CCTA acquisition: CCTA without a vasodilator ('baseline CT') and CCTA during continuous intravenous nitrate infusion ('IV nitrate CT'). A catheterized ergonovine provocation test was used to determine true VA patients. Coronary spasm is classified into focal- and diffuse-types according to morphological differences. We measured TAG and contrast enhancement of the proximal ostium (ProxHU) of each coronary artery for both the baseline and IV nitrate CT. Twenty-four patients (55.8%) showed positive results of coronary vasospasm on the provocation test. Thirty-eight vessels showed coronary spasms (29.5%): Focal-type in nine vessels (24%), and diffuse-type in 29 (76%). In the baseline CT, LCX showed significantly lower (steeper) TAG in spasm(+) vessels than in spasm(-) vessels, while LAD and RCA showed no significant differences in TAG. The ProxHU of LAD showed significantly lower values in spasm(+) vessels than in spasm(-) vessels, while the other vessels did not show significant differences in ProxHU. For IV nitrate CT, there were no significant differences in either the TAG and ProxHU between spasm(+) and (-) vessels for all the three vessel types. In subgroup analysis for spasm(+) vessels, diffuse spasms showed significantly lower TAG than focal spasms, while the ProxHU did not differ between the two types of spasm. A relatively large percentage of coronary spasms present as diffuse type, and the TAG values significantly differed according to the morphological type of the coronary spasm.

Impact of drug-eluting stent-associated coronary artery spasm on 3-year clinical outcomes: A propensity score matching analysis

BackgroundIt has been reported that significant endothelial dysfunction or clinically evident vasospasm can be associated with drug-eluting stents (DESs). However, the impact of DES associated coronary artery spasm (CAS) on long-term clinical outcomes has not been fully elucidated as compared with those of patients with vasospastic angina. MethodsA total of 2797 consecutive patients without significant coronary artery lesion (<70%), who underwent the Acetylcholine (Ach) provocation test, were enrolled between Nov 2004 and Oct 2010. DES-associated spasm was defined as significant CAS in proximal or distal to previously implanted DES site at follow-up angiography with Ach test. Patients were divided into two groups (DES-CAS; n = 108, CAS; n = 1878). For adjustment, propensity score matching (PSM) was done (C-statistics = 0.766, DES-CAS; n = 102, CAS; n = 102). SPSS 20 (Inc., Chicago, Illinois) was used to analyze this data. ResultsBaseline characteristics were worse in the DES-CAS group. After PSM, both baseline characteristics and the Ach test results were balanced except higher incidence of diffuse CAS and ECG change in the DES-CAS group. During Ach test, the incidence of diffuse spasm (93.1% vs. 81.3%, p = 0.012) and ST-T change (10.7% vs. 1.9%, p = 0.010) were higher in the DES-CAS group. At 3-year, before and after adjustment, the DES-CAS group showed a higher incidence of coronary revascularization (9.8% vs. 0.0%, p = 0.001), recurrent chest pain requiring follow up coronary angiography (CAG, 24.5% vs. 7.8%, p = 0.001) and major adverse cardiac events (MACEs, 9.8% vs. 0.9%, p < 0.005). ConclusionIn this study, DES associated CAS was associated with higher incidence of diffuse spasm, ST-T change and adverse 3-year clinical outcomes. Special caution should be exercised in this particular subset of patients.

84: DOES CHEST PAIN INFLUENCE NEGATIVELY LONG TERM CLINICALRESULTS OF THE SURGICAL TREATMENT FOR ESOPHAGEAL ACHALASIA?

Abstract Background and aim Recently it has been recommended not to perform the Heller myotomy in Achalasia type III (Chicago classification) because of the persistence of chest pain after surgery; alternatively, POEM was proposed. This position is based on short term follow up studies. In the last 40 years our group performed the Heller-Dor operation (HD) in achalasia diagnosed according to Vantrappen and Castell PMDE classification also in the presence of chest pain (vigorous achalasia included, diffuse spasm and nutcracker esophagus excluded). In cases operated upon of HD, we investigated in the long term chest pain, inside the global surgery evaluation. Methods Between 1978 and 2020, 390 achalasia patients underwent the Heller-Dor operation. Among them, 79 preoperatively complained of chest pain (group A), 311 did not (group B). Patients were preoperatively classified and postoperatively followed up according to a timed protocol based on clinical assessment of intensity and frequency of dysphagia (D0 absent—D3 daily), GERD symptoms (RS0 absent-RS3 daily); chest pain was quantified according to the Eckardt’s scale (0 none—3 each meal). Barium swallow and endoscopy (E0: normal, E1: mild esophagitis, E2–3: erosive/ulcerative esophagitis) were performed at each planned control. A and B groups were compared. Results Groups were homogeneous according to sex (P = 0.42) and age (P = 0.51). After HD median follow-up was 10 years (IQR 4.7–12.6 years) for A, 14 years (IQR 5.6–20 years) for B (P = 0.166); at barium swallow the percentage of decrease in esophageal diameter and barium column was similar (P = 0.59 and P = 0.85, respectively) as well as the frequency of GERD symptoms and esophagitis (P = 0.27). Chest pain progressively attenuated; median Eckard score preoperatively was 3, at follow-up it was 1 (P &amp;lt; 0.001). The clinical evaluation at the last control was significantly more favorable for A (satisfactory D0–2, RS0–2, and E1 in 95%) versus B (satisfactory in 89%) (P = 0.02). Conclusion In the long term HD achieves very satisfactory results with the decrease/disappearance of chest pain possibly present in regular achalasia. The clinical-radiological-manometric patterns of type 3 achalasia should be revised, to eliminate eventual misunderstandings.

MALIGNANT MULTI-VESSEL CORONARY ARTERY SPASM; A RARE CAUSE OF MYOCARDIAL INFARCTION LEADING TO CARDIOGENIC SHOCK – A CASE REPORT

Malignant multi-vessel coronary vasospasm is a rare life threatening condition, presentation like myocardial infarction (MI), arrhythmias, and cardiogenic shock (CS). We report a case of IWMI complicated by CS, angiogram shows diffuse multi-vessel coronary artery spasm. Intracoronary nitroglycerine showing improving spasm in culprit vessel RCA and distal RCA stented with excellent result. This case of early diagnosis of coronary artery spasm to prevent the occurrence of MI, arrhythmias and sudden cardiac death as it is one the rare cause. It also highlighted the role of intracoronary nitroglycerine in relieving diffuse multi-vessel vasospasm in hemodynamically unstable patient.

Acetylcholine Rechallenge: A First Step Toward Tailored Treatment in Patients With Coronary Artery Spasm.

The present study aimed to assess the feasibility and clinical value of acetylcholine (ACh) rechallenge for the detection of coexisting epicardial and microvascular spasm and to determine the efficacy of nitroglycerin in these spasm endotypes. The coexistence of epicardial and microvascular spasm is difficult to identify; thus, its frequency is unknown. Nitroglycerin treatment is equally recommended for both epicardial and microvascular coronary spasm despite contradictory data. In this multicenter study, 95 patients with coronary spasm were included to undergo ACh rechallenge, which consisted of repeated ACh provocation 3minutes after intracoronary nitroglycerin administration using the same dose that previously induced spasm. In total, 95 patients (age 61 ± 12 years, 69% female) were included. Fifty-five patients (58%) had microvascular spasm, and 40 patients (42%) had epicardial spasm during initial ACh provocation. In 48% of patients with epicardial spasm, ACh rechallenge revealed coexisting nitroglycerin-persistent microvascular spasm. Nitroglycerin administration before ACh rechallenge prevented reinducibility of epicardial spasm in all patients with focal spasm and in 80% of patients with diffuse spasm. Microvascular spasm was prevented in only 20% by prior nitroglycerin administration but was attenuated in another 49% of patients. This study demonstrates a high frequency of epicardial spasm with coexisting nitroglycerin-persistent microvascular spasm. Intracoronary nitroglycerin was very effective in preventing reinducibility of epicardial spasm, whereas it prevented microvascular spasm in only 20% of patients. ACh rechallenge is a novel method that facilitates the detection of coexisting spasm endotypes and may pave the way towards tailored treatment of vasospastic angina.
