Intra-aortic balloon pump still has a role in late-onset myocardial infarction complicated by ventricular septal rupture with intractable heart failure: a case report

BackgroundThe current guidelines have discouraged the routine use of intra-aortic balloon pump (IABP) in cardiogenic shock complicating acute coronary syndrome (ACS). Since then, the trend of IABP utilization in ACS has been declining. Nevertheless, the guidelines still preserve the recommendation of IABP use in hemodynamic instability or cardiogenic shock caused by post myocardial infarction (MI) ventricular septal rupture (VSR).Case presentationA 46-years-old diabetic Southeast Asian female was referred from a peripheral facility with intractable heart failure despite treatment with vasoactive agents and diuretics for five days. The ECG suggested a recent anteroseptal myocardial infarction with normal high-sensitivity troponin-I value. The echocardiography detected a regional wall motion abnormality and a 10 mm wide ventricular septal defect. Invasive coronary angiography revealed a severe two-vessel coronary artery disease. We planned a delayed surgical strategy with preoperative optimization using IABP as a bridge to surgery. IABP implantation followed by significant hemodynamic improvement and rapid resolution of heart failure without any inotrope support. Afterwards, coronary artery bypass grafting (CABG) and VSR surgical repair were performed. We safely removed IABP on the third postoperative day with proper weaning and minimal vasoactive support.ConclusionWe report a case where IABP still provided benefits for a patient with intractable heart failure caused by undetermined onset MI complicated by VSR. The use of IABP in such a case is in accordance with the recommendation of the current guidelines. Several studies showed that IABP use during preoperative optimization in the case of post-MI VSR was associated with survival benefits.

Perioperative Challenges and Outcome After Surgical Correction of Post-myocardial Infarction Ventricular Septal Rupture: A Retrospective Single Center Study.

Ventricular septal rupture (VSR) is a rare but grave complication of acute myocardial infarction (AMI). It is a mechanical complication of myocardial infarction where patients may present either in a compensated state or in cardiogenic shock. The aim of the study is to determine the in-hospital mortality. The study also aims to identify the predictors of outcomes (in-hospital mortality, vasoactive inotrope score (VIS), duration of ICU stay and mechanical ventilation in the postoperative period) and compare the clinical and surgical parameters between survivors and non-survivors. This is a retrospective study. The data of 90 patients was collected from the medical records and the data comprising of 13 patients who underwent VSR closure by single patch technique, or septal occluder, and those who expired before receiving the treatment, was excluded. The data of 77 patients diagnosed with post-AMI VSR and who underwent surgical closure of VSR by double patch technique was included in this study. Clinical findings and echocardiography parameters were recorded from the perioperative period. The statistical software used was SPSS version 27. The primary outcome was determining the in-hospital mortality. The secondary outcome was identifying the clinical parameters that are significantly more in the non-survivors, and the factors predicting the in-hopsital mortality and morbidity (increased duration of ICU stay, and of mechanical ventilation, postoperative requirement of high doses of vasopressors and inotropes). Subgroup analysis was done to identify the relation of various clinical parameters with the postoperative complications. The factors predicting the in-hospital mortality were illustrated by a forest plot. The mean age of the patients was 60.35 (±9.9) years, 56 (72.7%) were males, and 21 (27.3%) were females. Requirement of mechanical ventilation preoperatively (OR 3.92 [CI 2.91-6.96]), cardiogenic shock at presentation (OR 4 [CI 2.33 - 6.85]), requirement of IABP (OR 2.05 [CI 1.38-3.94]), were predictors of mortality. The apical location of VSR had been favorable for survival. The EUROScore II at presentation correlated with the postoperative VIS (level of significance [LS] 0.0011, R 0.36. The in-hospital mortality in this study was 33.76%. The in-hospital mortality of VSR is 33.76%. Cardiogenic shock at presentation, non-apical site of VSR, preoperative requirement of mechanical ventilation, high VIS preoperatively, perioperative utilization of IABP, prolonged CPB time, postoperative duration of mechanical ventilation, and high postoperative VIS were the factors associated with increased odds of in-hospital mortality.

Role of ECLS in Managing Post-Myocardial Infarction Ventricular Septal Rupture.

The aim of this study was to analyze outcomes in patients undergoing surgery for ventricular septal rupture (VSR) after myocardial infarction (MI) and the preoperative use of extracorporeal life support (ECLS) as a bridge to surgery. We included patients undergoing surgery for VSR from January 2009 until June 2021 from two centers in Germany. Patients were separated into two groups, those with and without ECLS, before surgery. Pre- and intraoperative data, outcome, and survival during follow-up were evaluated. A total of 47 consecutive patients were included. Twenty-five patients were in the ECLS group, and 22 were in the group without ECLS. All the ECLS-group patients were in cardiogenic shock preoperatively. Most patients in the ECLS group were transferred from another hospital [n = 21 (84%) vs. no-ECLS (n = 12 (57.1%), p = 0.05]. We observed a higher number of postoperative bleeding complications favoring the group without ECLS [n = 6 (28.6%) vs. n = 16 (64%), p < 0.05]. There was no significant difference in the persistence of residual ventricular septal defect (VSD) between groups [ECLS n = 4 (16.7%) and no-ECLS n = 3 (13.6%)], p = 1.0. Total in-hospital mortality was 38.3%. There was no significant difference in in-hospital mortality [n = 6 (27.3%) vs. n = 12 (48%), p = 0.11] and survival at last follow-up between the groups (p = 0.50). We detected no statistical difference in the in-hospital and long-term mortality in patients who received ECLS as supportive therapy after MI-induced VSR compared to those without ECLS. ECLS could be an effective procedure applied as a bridge to surgery in patients with VSR and cardiogenic shock.

Infarct exclusion repair of postmyocardial infarction ventricular septal rupture with a hybrid patch and septal occluder device compared with patch only

ObjectiveWe developed a hybrid technique for repairing post-myocardial infarction (MI) ventricular septal defect (VSD) that combines infarct exclusion with patch and a nitinol-mesh septal occluder device (SOD) to provide a scaffold to support the damaged septal wall. Here, we compare outcomes of patients with post-MI VSD repaired using patch only or hybrid patch/SOD. MethodsPatients undergoing post-MI VSD repair at our institution from 2013 to 2022 who received patch alone or patch/SOD repair were analyzed. Primary outcome was survival to hospital discharge. Clinical outcomes and echocardiograms were also analyzed. ResultsOver a 9-year period, 24 patients had post-MI VSD repair at our institution with either hybrid patch/SOD (n = 10) or patch only repair (n = 14). VSD size was 18 ± 5.8 mm for patch/SOD and 17 ± 4.6 mm for patch only. In the patch/SOD repair cohort, average size of SOD implant was 23.6 ± 5.6 mm. Mild left ventricular dysfunction was present prerepair and was unchanged postrepair in both groups; however, moderate-to-severe right ventricular (RV) dysfunction was common in both groups before repair. RV function worsened or persisted as severe in 10% of hybrid versus 54% of patch-only patients postrepair. Tricuspid annular systolic excursion and RV:left ventricle diameter ratio, quantitative metrics of RV function, improved after patch/SOD repair. No intraoperative mortality occurred in either group. Postoperative renal, hepatic, and respiratory failure requiring tracheostomy was common in both groups. Survival to hospital discharge in both cohorts was 70%. ConclusionsPost-MI VSD repair with patch/SOD has comparable short-term outcomes with patch alone. Addition of a SOD to patch repair provides a scaffold that may enhance the repair of post-MI VSD with patch exclusion.

Clinical assessment of VSR site and size and its relation to the severity of heart failure in post-myocardial infarction ventricular septal rupture patients.

Ventricular septal rupture (VSR) is a rare but well-known mechanical consequence of an acute myocardial infarction (AMI). Even in the later stages of re-perfusion therapy, the result of VSR remains poor. Our aim is to assess the site and size of VSR in relation to the severity of cardiac failure. From January 2016 to December 2022, a total of 71 patients with a diagnosis of post-myocardial infarction VSR were admitted to the First Affiliated Hospital of Zhengzhou University, Zhengzhou, China. Data records were retrospectively included in this registry. In all patients, clinical and echocardiographic data were gathered, and statistical analyses were performed. A total of 71 consecutive patients (mean age: 66.27 ± 8.88 years); 50.7% male, 49.3% female, with (M:F) ratio of almost (1:1). Left ventricular ejection fraction (LVEF) was (48.55 ± 10.44%) on echocardiography, and apical VSR was the most common site (69.0%). Overall, the VSD site was strongly related to the VSD size (p = .016), LVEF (p = .012), AMI site (p = .001), and affected coronary vessel (p = .004). Prodromal angina (p = .041), intra-aortic balloon pump (p = .002), affected coronary vessels (p = .020), pro-BNP (p = .000), and LVEF (p = .017) were predictors of the severity of heart failure. Diabetes mellitus is a common risk factor for post-myocardial infarction VSR. VSR site and size had no relation to the severity of heart failure. A presentation with prodromal angina predicted severe heart failure and a worse prognosis.

Early surgical outcomes of a modified infarct exclusion technique in acute post-myocardial infarction ventricular septal rupture: a single-centre experience.

Operative mortality in an acute post-myocardial infarction (AMI) ventricular septal rupture (VSR) is high. In addition to ventricular dysfunction, friable myocardium adds to the technical difficulty of the operation. In a modified infarct exclusion technique, the right ventricle is left undisturbed and the free edge of the pericardial patch is incorporated in the sutures while closing the left ventriculotomy. This simplifies the procedure and decreases the chances of right ventricular dysfunction, any residual defect, and bleeding. A retrospective analysis of patients with VSR following AMI operated in our institute from January 2018 to June 2021 was done. Over the last 3years, 16 patients with AMI VSR were treated with a modified infarct exclusion technique. Eight patients presented in cardiogenic shock preoperatively and were put on intra-aortic balloon pump support. All patients could be weaned successfully from the cardiopulmonary bypass, no patient had any residual defect, and none of the patients required re-exploration for bleeding. Postoperatively, 5 patients died within the first week and 2 more patients subsequently died due to intractable arrhythmias over the next 30days. In our centre, the mortality following repair of VSR after AMI was 43%. The modified infarct exclusion technique is a good technique with less chances of postoperative re-exploration and residual defect.

Unruptured Ventricular Septal Dissection Complicating Anterior Wall Myocardial Infarction

Interventricular septal dissection is a rare Complication of the interventricular septum. It may result from an aneurysm of the sinuses of Valsalva, bacterial endocarditis, trauma, cardiac surgery, Myocardial infarction, endomyocardial biopsy, or a congenital myocardial developmental anomaly. Postmyocardial infarction ventricular septal rupture (VSR) is a rare complication (1/1000), and ventricular septal dissection is an even less common complication with only five case reports previously described, But unruptured post Myocardial Infarction (MI) dissection is even rarer with only one reported study before. In this case report we describe an unruptured post-MI Interventricular septal dissection following anterior wall MI.

Survival in Patients with Post-myocardial Infarction Ventricular Septal Rupture: A Retrospective Observational Study

Introduction: Post-myocardial infarction ventricular septal rupture (post-MI-VSR) is a dreaded complication with high mortality. There is a varied survival pattern among patients who have undergone surgical repair. Aim: To assess the survival rates in patients who underwent surgical repair for post-MI-VSR in a single centre. Materials and Methods: A retrospective observational study was conducted in the Department of Cardiothoracic Surgery at Jayadeva Institute of Cardiovascular Sciences and Research, Bangalore, Karnataka, India. The patient records from January 2005 to December 2020, who underwent surgical repair of postMI-VSR, were reviewed. The perioperative variables, mortality, and survival data were analysed. Kaplan-Meier analysis was performed to assess the survival time. Results: The mean age of the studied patients was 58.4±7.5 years. A total of 73 patients underwent surgery for post-MIVSR. A total of 40 (55.80%) were males and 33 (45.20%) were females. Overall, 36 (49.32%) patients had diabetes, and 27 (36.99%) had hypertension. Anterior Myocardial Infarction (MI) (n=56, 76.71%) was the most common location of MI. The mean Cardiopulmonary Bypass (CPB) and clamp times were 144.05±59.09 and 105.38±38.34 minutes, respectively. The mean survival time was 2619.564 days {95% Confidence Interval (CI) 2105.936 to 3133.192}. Conclusions: As revascularisation confers a significant survival advantage, VSR repair with concomitant Coronary Artery Bypass Graft (CABG) appears beneficial.

Early outcome of surgical treatment of 20 cases of postinfartion ventricular septal rupture by extended sandwich patch technique via right ventricle approach

Objective: Different techniques have been described to repair post myocardial infarction ventricular septal rupture (VSR), each method may result in residual shunting, bleeding, and post-operative mortality. The aim of this report is to describe early results of extended sandwich technique through right ventricle in 20 consecutive patients.&#x0D; Patients and Methods: A retrospective, cross-sectional and descriptive study on 20 patients underwent surgery for myocardial infarction VSR by extended sandwich technique through right ventricle from 12/2018 to 3/2021 in Hanoi Heart Hospital.&#x0D; Result: 20 consecutive patients (10 women and 10 men) with postinfarction ventricular septal rupture (mean age 72 years, range 48-84) underwent surgical repair for by extended sandwich technique performed through right ventricle from December 2018 to August 2021 in our institute. Reconstruction of the septum was performed by two patches according to the method described by Asai et al. The mean aortic clamp time was 101. The mean extracorporeal circulation time was 143 min. Postoperative intensive care unit (ICU) stay averaged 4 days (range, 1-10 days). There was 30% hospital mortality. 10% postoperative residual shunting was detected, and no patient needed reoperation for bleeding.&#x0D; Conclusion: This method of extended sandwich technique through right ventricle was safe, simple, and it could be performed in acute phase of myocardial infarction.

In the modern era of reperfusion therapy, the incidence of post-myocardial infarction ventricular septal rupture has dramatically decreased by <1%, but unfortunately, it is still associated with high morbidity and mortality despite improvements in medical and surgical therapies. Percutaneous device closure of post-myocardial infarction ventricular septal rupture may be an alternative to surgical repair, with the advantage of immediate shunt reduction to prevent hemodynamic deterioration, especially in high-risk patients. Herein we report a case of post-myocardial infarction ventricular septal rupture which was successfully closed with an amplatzer atrial septal occluder device accompanied by cobrahead deformity in the right ventricular disc.

Transcatheter closure of post myocardial Infarction ventricular septal rupture with the Amplatzer Septal occluder

Ventricular septal rupture is a rare yet life threatening complication of acute myocardial infarction. Surgical closure is the treatment of choice however despite surgical intervention mortality remains high. Transcatheter closure of ventricular septal rupture has emerged as a new alternative strategy which is less invasive potentially allowing early hemodynamic stabilization. We report a case of a 60-year-old male with post infarction ventricular septal rupture who was treated with percutaneous closure using an Amplatzer device at Shahid Gangalal National Heart Centre, Nepal.

LEFT VENTRICULAR ANEURYSM AND VENTRICULAR SEPTAL DEFECT FOLLOWING MYOCARDIAL INFARCTION: A DANGEROUS COCKTAIL

An ischemic ventricular septal defect (VSD) is a lethal complication of myocardial infarction (MI), commonly from 24 hours to up to 5 days of presentation with AMI. Despite the improvement of surgical techniques, the mortality is still very high with poor prognosis. Left ventricular aneurysm (LVA) may also be a fatal mechanical complication of MI but rarely occurs in the posterior or inferior portion of the interventricular septum. Concomitant AMI mechanical complications in the same patient are less than infrequent with poor prognosis, particularly with late hospital arrival. We present an unusual case of post-myocardial infarction ventricular septal rupture (PI-VSR) combined with left ventricular inferior/inferoseptal aneurysm that was managed surgically. The aim of this article is to make clinician alerted in case of mechanical complication, especially when post-MI patients become hemodynamically unstable with refractory congestive heart failure.

Emergency Surgical Repair of Post Infarction Ventricular Septal Rupture

Ventricular septal rupture (VSR) is a life-threatening complication of myocardial infarction (MI). Surgery remains the only option; however it is still a challenging (1). Patients survive following medical management have poor outcome, so, its result is disappointing (2). Primary percutaneous coronary intervention (PCI) can be reduced VSR incidence. Medical treatment has high mortality, and early surgery is recommended to prevent hemodynamic deterioration. However, surgery also associated to a high of mortality rate (3). Transcatheter device closure is an option in critical cases (4).

Management of Post Infarction Ventricular Septal Rupture in Contemporary Era

IntroductionDuring the COVID-19 pandemic, there has been an increase in mortality and complications following STEMI. The rarity of ventricular septal rupture (VSR) in the age of primary percutaneous coronary intervention has resulted in a lack of expertise in its management. Our strategy has been to stabilize patients with venoarterial extracorporeal membrane oxygenation (VA ECMO) then evaluate for surgical repair with revascularization as well as advanced options, such as heart transplantation. Here we present two cases.Case 1A 65-year-old man with a history of hypertension presented to the hospital with an inferior STEMI and cardiogenic shock. He was found to have acute occlusion of the right coronary artery (RCA) through which a wire was not able to be passed. He also had severe disease in the left anterior descending artery (LAD) and left circumflex artery (LCx). An intra-aortic balloon pump (IABP) was placed. On hospital day 6, hemodynamics worsened and he was found to have a large VSR of the basal inferoseptum and biventricular dysfunction with a left ventricular ejection fraction (LVEF) of 10-15%. He was placed emergently on VA ECMO. Ten days later, he underwent repair of VSR and coronary artery bypass grafting (CABG) with a left internal mammary artery (LIMA) to LAD, and saphenous vein graft to an obtuse marginal. He underwent ECMO decannulation on post operative day 6. He was discharged home on post operative day 23 on medical therapy with an LVEF of 35%. He remains on medical therapy at 6 months.Case 2A 43-year-old man with a history of hypertension and diabetes suffered an inferoposterior STEMI. Coronary angiography showed acute occlusion of the RCA. He underwent thrombectomy and placement of two bare metal stents with no reflow, and placement of an IABP. He also had chronic occlusion of the LCx and 80% stenosis in the proximal LAD. A post procedure echocardiogram showed LVEF of 35-40%, severe right ventricular dysfunction, and VSR in the mid inferoseptum. He had worsening cardiogenic shock and underwent VA ECMO placement. On hospital day 9, he underwent VSR repair and single vessel CABG with LIMA to LAD. Due to inability to wean off bypass, he required placement of dual-pump biventricular support with Centrimag pumps after which he had persistent ventricular tachycardia. He was listed status 1A and underwent successful heart transplantation on hospital day 20. He is doing well at follow up.SummaryWe presented two cases of ventricular septal rupture complicating myocardial infarction, both with successful outcomes. During the COVID-19 pandemic, clinicians will need to maintain a high index of suspicion of mechanical complications of late presenting STEMI.
