The midterm outcomes of coronary artery bypass grafting for adult anomalous origin of the left coronary artery from the pulmonary artery

First report from the european registry for anomalous aortic origin of coronary artery (EURO-AAOCA).

Anomalous aortic origin of a coronary artery (AAOCA) is a group of rare congenital heart defects with various clinical presentations. The lifetime-risk of an individual living with AAOCA is unknown, and data from multicentre registries are urgently needed to adapt current recommendations and guide optimal patient management. The European AAOCA Registry (EURO-AAOCA) aims to assess differences with regard to AAOCA management between centers. EURO-AAOCA is a prospective, multicentre registry including 13 european centers. Herein, we evaluated differences in clinical presentations and management, treatment decisions and surgical outcomes across centers from 01/2019 to 06/2023. 262 AAOCA patients were included, with a median age of 33 years (12-53) with a bimodal distribution. 139 (53.1%) were symptomatic, whereas chest pain (n = 74, 53.2%) was the most common complaint, followed by syncope (n = 21, 15.1%). Seven (5%) patients presented with a myocardial infarction, two (1.4%) with aborted sudden cardiac death. Right-AAOCA (R-AAOCA) was most frequent (150, 57.5%), followed by left-AAOCA (L-AAOCA) in 51 (19.5%), and circumflex-AAOCA (Cx-AAOCA) in 20 (7.7%). There were significant differences regarding diagnostics between age groups and across centers. 74 (28.2%) patients underwent surgery with no operative deaths; minor post-operative complications occurred in 10 (3.8%) cases. Currently no uniform agreement exists among european centers with regard to diagnostic protocols and clinical management for AAOCA variants. Although surgery is a safe procedure in AAOCA, future longitudinal outcome data will hopefully shed light on how to best decide towards optimal selection of patients undergoing revascularization versus conservative treatment.

A report of fifty cases with incidental diagnosis of anomalous origin of the right coronary artery from the left sinus of Valsalva

IntroductionAnomalous origin of the right coronary artery from the left sinus of Valsalva (R-ACAOS) is a relatively rare condition that can potentially lead to devastating outcomes. The current study aims to investigate the cardiac-related disorders among patients with incidental R-ACAOS diagnosis through computed tomography angiography (CTA). MethodsThe current cross-sectional study has been conducted on 50 patients diagnosed with R-ACAOS who underwent CTA. Based on CTA, the patients' were categorized as R-ACAOS with interarterial course and non-interarterial course. The demographic and medical characteristics, any history of cardiac intervention and New York Heart Association (NYHA) Functional Classification at the time of diagnosis were recruited. Patients were revisited to assess cardiac-associated variables, including symptoms, the presence of heart failure and current NYHA function class. ResultsThe variables including the history of cardiac intervention (P-value<0.001), the presence of heart failure (P-value = 0.010) and NYHA function class at the time of diagnosis (P-value = 0.006) were remarkably higher among those with interarterial course of R-ACAOS; while, the other variables including chest pain at rest (P-value = 0.55) or on exertion (P-value = 0.12), current NYHA function class, current cardiac-associated symptoms except for dyspnea at rest (P-value = 0.012), mortality and coronary calium score did not differ (P-value>0.05). coronary interventions led to significantly improved NYHA function class (P-value<0.05). ConclusionBased on the findings of the current study, R-ACAOS with interarterial course leads to significantly higher rates of atherosclerotic-related symptoms and events compared with the other types of RCA anomalies. Moreover, coronary interventions led to significantly improved NYHA functional class regardless of R-ACAOS category.

High-Risk Anomalous Aortic Origin of the Left Coronary Artery: Consecutive Admissions Presenting With Sudden Cardiac Arrest.

Anomalous aortic origin of the left coronary artery (AAOLCA) confers high risk for sudden cardiac arrest (SCA). This series aims to describe consecutive admissions with interarterial AAOLCA presenting with SCA and distinct clinical trajectories. An eight-year-old boy collapsed at school and received 10-min of cardiopulmonary resuscitation (CPR) and defibrillation prior to return of spontaneous circulation. He had no end-organ dysfunction and underwent uneventful coronary unroofing. In contrast, a 14-year-old boy presented with collapse while jogging. He received 40-min of CPR prior to extracorporeal membranous oxygenation cannulation with multisystem dysfunction and persistent severely depressed left ventricular function. He is now rehabilitating following uneventful orthotropic heart transplantation. These cases illustrate the diverse outcomes of AAOLCA with SCA following exertional syncope.

Stillbirth Associated With Anomalous Origin and Course of the Left Coronary Artery: A Report of 2 Cases.

Coronary artery anomalies and their potential sequelae are not well studied in association with stillbirth. Herein, we report the autopsy findings in two term stillborn fetuses with coronary artery anomalies. Both fetuses showed identical findings consisting of an abnormal origin of the left coronary artery from the right sinus of Valsalva and an interarterial course of the left coronary artery. Histologic vascular and myocardial changes were also present. These coronary artery findings are associated with sudden death in adults and neonates, and therefore, their potential to be a cause and/or contributor to fetal death is suspected.

Anomalous origin of right coronary artery from the pulmonary artery: an incidental finding on cardiac computed tomography in a patient presenting with dyspnea

Anomalous right coronary artery originating from the pulmonary artery (ARCAPA) is rare with an incidence of 0.002%. It usually presents in adulthood with symptoms of angina and is often associated with other congenital anomalies. We report a case of ARCAPA, that was diagnosed on investigation of dyspnea on exertion.

[Diagnosis and surgical treatment of high-risk anomalous aortic origin of coronary artery].

Objective: To analyze the diagnosis and surgical treatment of high-risk anomalous aortic origin of coronary artery (AAOCA). Methods: This is a retrospective case series study. From January 2016 to July 2023, 24 cases of high-risk AAOCA underwent surgical treatment in Department of Cardiac Surgery, Guangdong Provincial People's Hospital. There were 18 males and 6 females, operatively aged (M (IQR)) 13 (26) years (range: 0.3 to 57.0 years). They were confirmed by cardiac ultrasound and cardiac CT, all of which had anomalous coronary running between the aorta and the pulmonary artery. There were 15 cases of the right coronary artery from the left aortic sinus of Valsalva, 6 cases of left coronary artery from the right aortic sinus of Valsalva, 3 cases of the sigle coronary artery. Only 3 patients had no obvious related symptoms (2 cases were complicated with a positive exercise stress test and 1 case with other intracardiac malformations), 21 cases had a history of chest tightness, chest pain, or syncope after exercise. Three patients suffered syncope after exercise and underwent cardiopulmonary resuscitation (2 cases were treated with an extracorporeal membrane oxygenerator (ECMO)). The gap from the first symptom to the diagnosis was 4.0 (11.5) months (range: 0.2 to 84.0 months). The detection rate of coronary artery abnormalities suggested by the first cardiac ultrasound was only 37.5% (9/24). Seven patients were complicated with other cardiac diseases (4 cases with congenital heart defects, 2 cases with coronary atherosclerotic heart disease, 1 case with mitral valve disease). Results: All 24 patients underwent surgical treatment (23 cases underwent abnormal coronary artery unroofing, 1 case underwent coronary artery bypass grafting), and 5 patients underwent other intracardiac malformation correction at the same time. There were no death or surgery related complications in the hospital for 30 days after the operation. A patient with preoperative extracorporeal cardiopulmonary resuscitation was continuously assisted by ECMO after emergency AAOCA correction and had complications such as limb ischemia necrosis and renal dysfunction after the operation. During the follow-up of 2.2 (3.3) years (range: 1 month to 7.2 years), one patient who previously underwent percutaneous transluminal coronary angioplasty with a stent implant experienced significant postoperative symptomatic relief, and the other discharged patients had no related symptoms. Conclusions: The accurate rate of initial diagnosis for high-risk AAOCA is still low, but the risk of cardiovascular accidents is high. For sports-related chest pain and other symptoms, more attention should be paid to the detection of AAOCA, especially for adolescents. Exercise stress testing can be helpful in evaluating the cardiovascular risk of asymptomatic AAOCA. Instant surgical treatment can achieve satisfactory curative effects.

Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery Diagnosed in Adulthood

Introduction: An anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare heart malformation, with 90% of patients dying during the first year of life. If the right coronary artery compensation and multiple collateral circulation are sufficiently established, the patient's myocardial ischemia symptoms are mild and appear later, which is called the adult type ALCAPA. Case Description: A 42-year-old woman presented to our hospital with one-month history of the aggravation of active shortness of breath which gradually progressed to nocturnal paroxysmal shortness of breath and cough. Admission physical examination suggested mild edema of both lower limbs. Transthoracic echocardiography (TTE) showed that a small vessel shadow was abnormally connected to the pulmonary artery (PA), and moderate pulmonary artery hypertension. Coronary computed tomography angiography (CTA) showed an anomalous origin of the left main coronary artery (LMCA) dividing into the left anterior descending (LAD) and left circumflex (LCX) artery from the PA, with no clear connection to the left coronary sinus. The right coronary artery (RCA) was significantly dilated and originated from the normal Valsalva sinus. It was accompanied by multiple collateral circulations, most of which traveled anterior to the right ventricular free wall and anterior interventricular sulcus, and some emanated from the posterior descending branch of the posterior interventricular sulcus and walked toward the posterolateral wall of the left ventricle. Conclusion: Coronary computed tomography angiography (CTA) can be used to visualize the abnormal origin and distribution of the coronary artery's course and may be the first choice in the diagnosis of ALCAPA.

Tetralogy of Fallot with an anomalous origin of right coronary artery from the pulmonary artery in a case of type i aortopulmonary window—A diagnostic challenge

&lt;p&gt;Aortopulmonary (AP) window is a conotruncal defect with an incidence of &amp;lt; 1% amongst congenital heart defects. It often occurs in association with other congenital cardiac defects. Coronary artery anomalies in association with the AP window are infrequent. An anomalous right coronary artery (RCA) from the pulmonary artery (ARCAPA) is an extremely rare entity with 0.002% incidence in the general population. To the best of our knowledge, the triad of Tetralogy of Fallot (TOF), ARCAPA and AP window is not yet reported in the literature.&lt;/p&gt;

Transcatheter Pulmonary Valve Implantation in Repaired Tetralogy of Fallot and Anomalous Left Coronary Artery Origin

We describe a rare and extremely challenging case of transcatheter pulmonary valve implantation in repaired tetralogy of Fallot and anomalous origin of the left main coronary artery from the right coronary sinus. Procedural planning based on advanced multimodality imaging and 3-dimensional technology proved to be the key to procedural success.

Fatal Coronary Artery Anomaly Concealed in Young Athletes with Exertional Syncope

Background. Syncope is a common symptom in children, many of which are benign and do not require treatment. Anomalous aortic origin of a coronary artery (AAOCA) is a rare congenital malformation but can be a risk for serious cardiovascular events, including sudden death as well as cardiogenic syncope. Case Report. We describe the case of a 14-year-old boy who suffered an initial syncope and afebrile seizure during a soccer game. A detailed medical history and imaging studies led to the diagnosis of the anomalous aortic origin of the left main coronary artery with an intramural course (AAOLCA-IM). Conclusion. Symptomatic AAOLCA-IM has the highest risk of sudden death among AAOCA, and surgical repair may be performed. Onset during exercise or preceding chest symptoms are suspicious signs of cardiogenic syncope and should be considered for cardiovascular imaging evaluation.

Interposition of right internal iliac artery free-graft for left coronary artery reimplantation in adults with anomalous left coronary artery originating from the pulmonary artery: case series and long-term results.

Anomalous left coronary artery originating from the pulmonary artery (ALCAPA) is an infrequent congenital anomaly. Presentation of this syndrome is rare in adults. Nevertheless, adult patients are at risk of ischaemia, arrhythmias or sudden cardiac death and always require surgical intervention. At our institution, a specific technique of interposition of the right internal iliac artery as a free-graft for left coronary artery reimplantation was used in adult ALCAPA patients. The aim of this report is to determine long-term results and experiences with this surgical technique.

Surgical Management of Anomalous Right Coronary Artery in the Adult: Technique and Case Series

The management of adult patients with anomalous aortic origin of the right coronary artery (ARCA) from the left aortic sinus poses important challenges. The presence of symptoms or documented ischaemia, the anatomical characteristics of the ostium, and the course of the coronary determine decision-making. A retrospective review was performed of all cases of surgical management of ARCA at a single centre. The primary endpoints were mortality and myocardial infarction at 30 days. Secondary endpoints included recurrence of symptoms, freedom from re-intervention, and mortality during long-term follow-up. From October 2019 to August 2023, 15 adult patients underwent surgery for ARCA; 13 patients were included in this study (mean age 53.9±11.1 years; 10 female). A slit-like orifice, a long intramural segment, and an interarterial course were found in all patients. Twelve (12) patients (92.3%) were symptomatic: nine with angina, combined with dyspnoea on exertion in seven. One (1) patient had history of pre-syncope. One (1) patient presented with out-of-hospital cardiac arrest. All patients underwent formal unroofing of the orifice and intramural portion of the ARCA; five patients had a concomitant procedure. No 30-day mortality nor myocardial infarction was recorded. At a mean follow-up of 20.1±12.8 months, all patients were alive. One (1) patient (7.6%) developed recurrent dyspnoea; investigations showed no ischaemia. No repeated interventions were required. Surgical unroofing of anomalous coronary artery in the adult is safe and effective; correction of both the slit-like orifice and intramural portion of the anomaly provides a durable result in patients with ARCA.

Case report: A case of an anomalous right coronary artery arising from the left coronary cusp.

Abstract&#x0D; An anomalous origin of the right coronary artery is usually asymptomatic. It is mostly found incidentally on an invasive diagnostic angiogram. It does lead to an increased risk of sudden cardiac death, especially in younger patients. We present a case of a 41-year-old who had presented to the hospital with complaints of chest pain. The patient was evaluated by cardiology who performed an angiography that identified an anomalous origin of the right coronary artery arising from the left coronary cusp but no evidence of coronary artery disease. Once identified, these anomalous vessels should be corrected surgically, as these conditions increase the risk of sudden cardiac death arrhythmia and ischemic events.&#x0D;  &#x0D; INTRODUCTION&#x0D; Anomalous aortic origin of the right coronary artery (AAORCA) is an uncommon congenital malformation with varying clinical presentations ranging from asymptomatic to sudden cardiac death (SCD). Those with symptoms or high-risk lesions are usually managed by unroofing or reimplantation, coronary artery bypass graft (CABG), AAORCA treated with right internal memory artery graft with proximal RCA ligation.&#x0D;  &#x0D; CASE DESCRIPTION&#x0D; A 41-year-old female patient with obesity and hypertension presented with a 1-year history of intermittent exertional substernal pressure radiating to left shoulder and back. The pain, which lasted about 10 minutes per episode, had been more frequent and intense over the past week.Upon initial evaluation, she was hypertensive at 150/90 mmHg and heart rate  60 bpm. Blood work was unremarkable, including negative serial troponin levels. Electrocardiography showed sinus bradycardia without ischaemic changes. Anomalous origin of RCA was incidentally discovered from computed tomography (CT) of the chest. Coronary angiography and ascending aortography were then performed, which revealed a patent RCA originating from the left coronary cusp (Fig. 1A). CT heart angiography with reconstruction revealed the RCA ostium in the left coronary cusp with a malignant course between the aorta and pulmonary artery and without an obvious intramural segment&#x0D; Discussion:&#x0D;  &#x0D;  An anomalous origin of the right coronary artery (RCA) is a rare congenital anomaly that was first described in 1948 by White and Edwards. After carrying out angiography in 126,595 patients, Yamanaka and Hobbs reported the incidence of anomalous origin of the right and left coronary arteries as 136 (0.107%) and 22 (0.017%), respectively. The prevalence of an anomalous origin of RCA (ARCA) arising from the left coronary cusp with an inter-arterial course varies between 0.026% and 0.25%. An ARCA is more common than the anomalous origin of the left coronary artery (ALCA), but the latter is shown to be responsible for up to 85% of sudden cardiac deaths (SCD) related to the anomalous origins of arteries. Most coronary anomalies are detected incidentally on diagnostic angiography and are clinically insignificant; some, however, have been associated with an increased risk of SCD. It is second only to hypertrophic cardiomyopathy as a leading cause of SCD in young athletes. Mechanical compression of the RCA by the great vessels, which dilate and compress the RCA during periods of increased stroke volume, is the usual explanation for coronary ischemia. Patients usually have no ischemic changes on an electrocardiogram (ECG) at rest; however, multi-detector computed tomography (MDCT) is being used to evaluate the course of anomalous vessels outlying their relative positions to the aorta and the pulmonary artery. It also gives additional information regarding any stenotic lesion in these anomalous vessels. Echocardiography (Echo), magnetic resonance angiography (MRA), MCDT, and cardiac catheterization are all complementary diagnostic tools for evaluating anomalous coronary arteries [10]. While it is agreed that surgical correction is the standard of care for ALCA, when found, the management for right ARCA is more complicated. Treatment options for these patients include observation with medical therapy, percutaneous intervention (stenting), or surgery. Early diagnosis of coronary artery anomalies based on the patients’ symptoms can help decrease the incidence of sudden cardiac deaths, fatal arrhythmias, and ischemic events in the high-risk population.&#x0D;  &#x0D; Conclusions &#x0D;  &#x0D; Coronary anomalies should be suspected in symptomatic young patients with a normal cardiac workup. Non-invasive imaging modalities such as a CTCA can help establish the diagnosis

Technical Details of a Novel Surgical Procedure of Anomalous Left Coronary Artery from the Pulmonary Trunk in a Child Using Autogenous Aortic and Pulmonary Arterial Flaps (UKC’s Modification): A Video Presentation

A 18-months-old male child diagnosed with anomalous origin of left coronary artery from the left posterior pulmonary sinus underwent the modification of the “trapdoor” technique, wherein the anomalous left coronary artery was detached from the pulmonary arterial sinus, and combined aortic and pulmonary arterial flaps were used to augment its length. The postoperative recovery was uneventful.

Dobutamine Stress Cardiovascular Magnetic Resonance Derived 2-Dimension Feature Tracking Strain Analysis in Pediatric Population with Anomalous Aortic Origin of Right Coronary Artery.

Anomalous aortic origin of right coronary artery (AAORCA) is associated with myocardial ischemia and sudden cardiac arrest/death. Risk stratification remains challenging and relies upon provocative test results. This study describes the utility of dobutamine stress cardiovascular magnetic resonance (DSCMR) and potential benefit of strain analysis in children with AAORCA. All patients less than 21years of age with AAORCA who underwent DSCMR between July 2018 and December 2022 were included. Visual wall motion abnormalities (VWMA) at rest and during protocolized increments of dobutamine infusion were assessed. Regional and global left ventricular circumferential (GCS) and radial (GRS) strain using 2-dimension Feature tracking (2D-FT) analysis (cvi42, Circle Cardiovascular Imaging Inc.) were calculated at rest and peak response. Of the total 54 DSCMR studies performed in 51 children with median age (IQR) of 13.5 (11-15)years, FT analysis was reliably performed in 52 (96%) studies. None had VWMA. The absolute change in GCS and GRS from rest to peak dobutamine stress was 4% (1-6%) and 11% (4-18%), respectively. There was no significant difference in GCS and GRS in patients with exertional symptoms vs no/non-exertional symptoms as well as between those considered to be high-risk vs low-risk anatomical features. DSCMR-derived 2D-FT strain analysis is feasible to assess myocardial deformation in children with AAORCA and may enhance this method of provocative testing. Although there were no statically significant differences in GCS and GRS values between high and low-risk subgroups, the absolute change in GCS between rest and peak stress is diminished when compared to normal adult reports.

Hidden Coronary Artery Ostium and Sudden Death.

A 1-week-old girl died suddenly and unexpectedly. At autopsy the major finding was of a right dominant coronary artery circulation with an inapparent left coronary artery ostium. After careful examination, an anomalous origin of the left coronary artery was found with the ostium located in the non-coronary cusp immediately adjacent to the commissure of the non- and left coronary cusps. The ostium was of small caliber with an obliquely oriented artery (<45°) with no ostial ridges. The artery coursed anteriorly past the left coronary cusp between the aorta and the left atrial appendage to then follow its usual course inferiorly along the anterior aspect of the left ventricle. The reminder of the autopsy was unremarkable. Death was, therefore, attributed to an anomalous and hypoplastic left coronary artery (and ostium) with an acute angle of take-off. Tracing coronary arteries in the very young may be technically difficult due to their small size, thus identifying the location of ostia is important. This may be difficult when the ostium was located close to a commissure.

Adult-type anomalous origin of the left coronary artery from the pulmonary artery and right coronary-right atrial fistula: a case report

BackgroundAnomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital cardiac anomaly, mortality rates in infancy reach approximately 90%, with only a small number of patients surviving into adulthood, therefore, most of the literature reports mainly focus on infantile type.Case presentationA 55-year-old female was admitted due to persistent repeated chest pain experienced and had worsened for unknown reasons. Color doppler echocardiography, coronary computed tomographic angiography, and coronary angiography confirmed the diagnosis of ALCAPA and concurrent right coronary artery-right atrial fistula. The symptoms of chest pain exhibited notable improvement subsequent to corrective surgery for the anomalous origin of the coronary artery.ConclusionsThis report shows an unique case of ALCAPA in an adult patient, characterizing the condition’s combination with a right coronary-right atrial fistula, and it is prone to misdiagnosis and misdiagnosis. We aim to provide valuable insights for clinical diagnosis and treatment of ALCAPA.

Anomalous left coronary artery from the pulmonary artery (ALCAPA) in adult patients - a multimodality imaging approach.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital ano-maly of the origin of the coronary arteries. The prevalence of this anomaly in the adult patient population is low, and therefore there is virtually no original research on this topic. Reports are limited to case reports. We evaluated 16,264 computed tomography (CT) exams (cardiac and chest) performed in our heart imaging department between 2015 and 2022 on a dual-source 128-slice CT scanner (SOMATOM Definition Flash, Siemens Healthineers, Forchheim, Germany) and established a retrospective registry of adult patients (> 18 years old) with ALCAPA. The study included 7 cases. Next, we collected clinical and echocardiographic data, which could be assessed retrospectively. We found 7 cases of ALCAPA in adult patients (0.043%). Three of them were female, and 4 were male. The age varied between 20 and 60 years. Echocardiographic findings, as well as the clinical course, varied widely. ALCAPA is an extremely rare anomaly, which nonetheless must be taken into clinical consideration. This lesion may be fatal during infancy. Data regarding adult patients is scarce. Multicentre registries are needed to establish a more detailed clinical profile of adults with this anomaly.
