Surgical treatment for a child with traumatic ventricular septal rupture and ventricular aneurysm.

A five-year-old boy was diagnosed with the ventricular septal rupture and ventricular aneurysm after blunt chest trauma in child abuse. Because of the intractable heart failure, he underwent operation in subacute period. Postoperative course was uneventful. The blunt cardiac injury in children can be caused by mild trauma and can be lethal. Surgical intervention should be considered when the clinical condition is unstable.

[Giant Left Ventricular Aneurysm After Double Patch Closure of Ventricular Septal Perforation Through Right Ventriculotomy].

A 66-year-old man. He had myocardial infarction due to occlusion of the left anterior descending branch, which was subsequently complicated by ventricular septal perforation. Ventricular septal perforation was repaired through right ventricle incision, applying double patches for closure, and injecting glue between the patches. The early postoperative course was good, but the infarcted left ventricular anterior wall remained because of the right ventriculotomy approach. A left ventricular aneurysm was demonstrated on postoperative follow-up echocardiography, which gradually enlarged to become giant. Since symptoms of heart failure such as respiratory distress appeared, left ventriculoplasty was performed 29 months after the perforation of the initial surgery. Since thinned left ventricular wall remains following right ventriculotomy approach, risk of postoperative left ventricular aneurysm should be taken into account.

En mann i 60-årene med dyspné og systolisk bilyd etter hjerteinfarkt.

Background: Ventricular septal rupture (VSR) following acute myocardial infarction is rare in the modern revascularisation era. Nevertheless, clinical awareness is paramount, as presentation may vary. Case presentation: A middle-aged male with no history of cardiovascular disease developed progressive heart failure symptoms while travelling abroad. Initial workup revealed a prominent systolic murmur, but findings were inconsistent with acute coronary syndrome. Transthoracic echocardiogram showed a small hypokinetic area in the basal septum, preserved left ventricular function and no significant valvulopathy. Despite the absence of chest pain, an invasive angiography revealed occlusion of a septal branch emerging from the left anterior descending artery, otherwise patent coronary arteries. Despite administration of diuretics, the patient remained symptomatic and presented two months later to his primary care provider with a persisting systolic murmur. He was subsequently referred to the outpatient cardiology clinic where echocardiography revealed a large VSR involving the basal anteroseptum of the left ventricle with a significant left-to-right shunt. After accurate radiological and haemodynamic assessment of the defect, he successfully underwent elective surgical repair. Interpretation: Although traditionally associated with large transmural myocardial infarctions, VSR may arise also from minor, subclinical events. A new-onset murmur is a valuable hint for the alert clinician.

ST-Elevation myocardial infarction patient with ventricular septal rupture complication: A Case Report.

Abstract: Ventricular septal rupture (VSR) is an uncommon but very significant mechanical complication of acute myocardial infarction (AMI), with typically severe hemodynamic effects. Until surgical closure of the defect and revascularization of the coronary bypass surgery graft (CABG), the patient at Wahidin Sudirohusodo Hospital with VSR reports sequelae of MI with stable hemodynamic condition.

Multicentre short- and medium-term report on the device closure of a post-myocardial infarction ventricular septal rupture - In search of risk factors for early mortality.

BACKGROUND: Post-myocardial infarction ventricular septal rupture (VSR) is a rare and severe complication of myocardial infarction. To find early mortality (<30 days) risk factors of device VSR closure and to evaluate its medium-term outcome. METHODS: Multicenter retrospective analysis on all 46 consecutive patients with percutaneous (n = 43) or hybrid (n = 3) VSR closure in 2000-2020 with various nitinol wire mesh occluders. Medical records, hemodynamic data, procedure results, short- and mid-term follow-up were analyzed (4.8 ± 3.7 years, range: 0.1-15, available in 61.7% of patients). Of the patients, 34.8% underwent VSR closure in acute phase (<21 days after VSR occurrence), 17.4% underwent device closure due to significant residual shunt after previous VSR surgery. RESULTS: Success rate was 78.3%. More than moderate residual shunt, major complications, and early surgical reintervention affected 18.9%, 15.2% (including 2 intra-procedural deaths), and 21.7% of patients, respectively. Early mortality was 26.1% (13.9% in successful vs. 70% in unsuccessful closure; p < 0.001). Older age, need for intra-aortic balloon counterpulsation, severe complications, and procedural failure were identified as risk factors for early mortality. Among patients who survived the early period, the 5-year survival rate was 57.1%. NYHA class improved in 88.2% patients at the latest follow-up. CONCLUSIONS: Procedure of VSR device closure demonstrates an acceptable technical success rate; however, the incidence of severe complications and early mortality is notably high. Older patients in poor hemodynamic condition and those with unsuccessful occluder deployment are particularly at a higher risk of a fatal outcome. The prognosis after early survival is promising.

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.

BACKGROUND: The 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 PRESENTATION: A 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. CONCLUSION: We 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.

The left ventricular "lining" technique for repair of ischemic ventricular septal rupture.

We describe a technique to repair ischemic ventricular septal rupture via a left ventriculotomy. It employs a large endoventricular patch as a "lining" over the locally patched septal defect and the free wall defect which is going to be roofed with an external patch. Both defects are then closed in double layers, holding a single continuous patch. The technique enhances the advantage of the left ventriculotomy in the repair and minimizes ventriculotomy-related morbidity.

Delayed Giant Pseudoaneurysm With Left-to-Right Shunt Following Postinfarct Ventricular Septal Perforation Repair.

Left ventricular pseudoaneurysm with a left-to-right shunt is extremely rare, requiring surgery if symptomatic; however, surgery has a high risk. Here, the case of a 77-year-old man with heart failure symptoms is reported, in which he develops a giant left ventricular pseudoaneurysm 16 months after ventricular septal perforation repair as a result of acute myocardial infarction, with mild shunt blood flow from the pseudoaneurysm to the right ventricle. Intraoperative findings showed a free wall rupture along the area where the patch was secured during the initial surgery. The patient was discharged on postoperative day 13, and postoperative examination revealed no abnormalities.

Long-Term Results and Risk Factors of Treatment for Post-Infarction Ventricular Septal Rupture: A Single-Center Experience.

BACKGROUND: Ventricular septal rupture (VSR) following myocardial infarction (MI) is a rare but lethal complication. We analyzed the long-term results and risk factors for survival in the treatment of VSR. METHODS: From January 2012 to December 2021, 115 consecutive patients with post-MI VSR were admitted to our hospital. Depending on different treatment methods patients were divided into following three groups: medical, transcatheter intervention, and surgical repair. During the study, relevant clinical data, operation-related conditions, and follow-up data were analyzed. The Kaplan-Meier method and log-rank test were used to determine the cumulative incidence of mortality. The independent risk factors for patient mortality were evaluated by multivariate logistic regression. RESULTS: The mean follow-up time was 43.4 ± 34.7 months. The overall in-hospital, 30-day, and long-term mortality rates were 24.3%, 38.3%, and 51.3%, respectively. In the medical group, the in-hospital and 30-day mortality rates were 46.7 % (21/45) and 82.2 % (37/45), respectively, with only three patients alive at follow-up. In the transcatheter intervention group, 30-day and long-term mortality rates were 12% and 28%, respectively. In the surgical repair group, 30-day and long-term mortality rates were 8.9% and 22.2%, respectively. Compared with the surgery-group patients, patients with transcatheter intervention had a longer time from VSR to intervention. Logistic regression analysis revealed that age, previous infarction, Killip class, serum creatinine, Troponin T, N-terminal pro-B-type natriuretic peptide, and medical strategy were risk factors for all-cause mortality. CONCLUSIONS: The 30-day and long-term outcomes of patients treated with surgical repair and transcatheter intervention were significantly better than medically treated patients.

Role of echocardiography in the management of ventricular septal rupture after acute myocardial infarction.

Ventricular septal rupture (VSR) is a rare and devastating complication of acute myocardial infarction. Early detection, assessment of the hemodynamic impact, and illustration of the pathophysiological context are crucial functions of echocardiography in decision-making for intensive management and reparative intervention. To evaluate this entity, echocardiography exhibits two strengths: its bedside nature and its multiple modalities. This document reviews the comprehensive use of echocardiography in the study of post-infarction VSR.

Advent of severe mitral regurgitation in surgical ventricular restoration and ventricular septal rupture repair.

BACKGROUND: Per-procedural severe mitral regurgitation is a rare complication in concomitant surgical ventricular restoration and postinfarction ventricular septal rupture repair. It is challenging to discover the underlying etiology and adopt an appropriate strategy, in particular, in a high-risk patient. CASE PRESENTATION: Semi-emergent surgical ventricular restoration combined with ventricular septal rupture closure and coronary artery bypassing was performed in a 67-year-old male patient. Severe mitral regurgitation was detected after the weaning of cardiopulmonary bypass. Two key questions arose in the management of this condition: did the regurgitation exist previously and was dissimulated by significant left-to-right shunt, or it occurred secondarily to the Dor procedure? Which was the better management strategy, chordal-sparing mitral valve replacement or mitral plasty? We believed that severe mitral regurgitation was under-estimated pre-operatively and we performed an downsizing annuloplasty to treat mitral regurgitation. The outcomes were promising and the patient did well in follow-up. CONCLUSIONS: Our case brought out an open discussion on the etiology and therapeutic strategies of this complicated condition.

A rare case of concurrent left ventricular aneurysm and ventricular septal rupture complicating an inferior myocardial infarction: a case report.

Complications following acute myocardial infarction (MI) such as ventricular septal rupture (VSR) and left ventricular (LV) aneurysm are rare and can be dreadful. Their simultaneous presence in the same patient is extremely rare. We aimed to present a rare case of concomitant association of ventricular aneurysm and VSR complicating an inferior myocardial infarction. We report the unusual case of Mr. A. D, a 63-year-old, active smoker, with a history of diabetes mellitus and hypertension, admitted for the management of inferior MI within 6 days. The MI was complicated by an LV aneurysm in the inferoposterior and the inferoseptal walls associated with a VSR in the inferoseptal wall. The patient had only signs of right heart failure on admission. This observation illustrates on the one hand the rarity of the association of VSR and LV aneurysm after an inferior myocardial infarction, and on the other hand the possibility of founding them at an early stage of MI without any signs of cardiogenic shock.

[Semi-acute Surgery for Ventricular Septal Perforation After Unsuccessful Intra-aortic Balloon Pumping Support:Report of a Case].

Ventricular septal perforation( VSP) after acute myocardial infarction( MI) is a serious condition that requires surgical treatment. However, good outcome is not always obtained. The mortality rate of VSP is particularly high in cases whom emergency surgery is performed early in the course of the disease, and the timing of surgery is known to affect prognosis. In this case report, the patient assisted with intra-aortic balloon pump. VSP closure surgery (a modified David-Komeda technique) underwent 8 days after MI onset. Except for mild residual shunt, the patient experienced no adverse event during postoperative course and was discharged 30 days after the surgery. This case illustrated timing of surgery as well as adequate mechanical cardiopulmonary assistance and surgical technique is important.

Percutaneous Closure vs. Surgical Repair for Postinfarction Ventricular Septal Rupture: A Systematic Review and Meta-Analysis.

INTRODUCTION: Ventricular septal rupture is an important high-mortality complication in the scope of myocardial infarctions. The effectiveness of different treatment modalities is still controversial. This meta-analysis compares the efficacy of percutaneous closure vs. surgical repair for the treatment of postinfarction ventricular septal rupture (PI-VSR). METHODS: A meta-analysis was performed on relevant studies found through PubMed®, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure (or CNKI), Wanfang Data, and VIP databases searching. The primary outcome was a comparison of in-hospital mortality between the two treatments, and the secondary outcome was documentation of one-year mortality, postoperative residual shunts, and postoperative cardiac function. Differences were expressed as odds ratios (ORs) with 95% confidence intervals (CIs) to assess the relationships between predefined surgical variables and clinical outcomes. RESULTS: Qualified studies (742 patients from 12 trials) were found and investigated for this meta-analysis (459 patients in the surgical repair group, 283 patients in the percutaneous closure group). When comparing surgical repair to percutaneous closure, it was found that the former significantly reduced in-hospital mortality (OR: 0.67, 95% CI 0.48-0.96, P=0.03) and postoperative residual shunts (OR: 0.03, 95% CI 0.01-0.10, P<0.00001). Surgical repair also improved postoperative cardiac function overall (OR: 3.89, 95% CI 1.10-13.74, P=0.04). However, there was no statistically significant difference in one-year mortality between the two surgical strategies (OR: 0.58, 95% CI 0.24-1.39, P=0.23). CONCLUSION: We found that surgical repair appears to be a more effective therapeutic option than percutaneous closure for PI-VSR.

Early and Late Surgical Outcomes after Geometrical Infarct Exclusion for Post-Infarct Ventricular Septal Perforation.

PURPOSE: Ventricular septal perforation (VSP) is a critical complication of acute myocardial infarction. Various surgical procedures for it have been developed; however, surgical outcomes remain unsatisfactory. In 2010, we introduced geometrical infarct exclusion (GIE) as a modification of the Komeda-David technique. This retrospective study compared the surgical outcomes of our geometric infarct exclusion technique to those of other surgical procedures. METHODS: This study included 38 patients who underwent surgery for VSP. They were divided into patients who underwent GIE (GIE group; n = 17) and those who underwent other procedures (non-GIE group; n = 21). The clinical outcomes of the two groups were compared. RESULTS: Operation, cardiopulmonary bypass, and cardiac arrest times in the GIE group were significantly longer than those in the non-GIE group (p <0.001). A residual shunt was observed in one patient (5.8%) in the GIE group and eight (38.0%) in the non-GIE group (p = 0.026). No patients in the GIE group required a reoperation for the residual shut, while two patients required it in the non-GIE group (p = 0.492). Operative mortality was insignificantly different between the two groups. CONCLUSION: Geometric infarct exclusion has a longer procedural time than does other surgical procedures but can reduce the rates of residual shunts and reoperations.

Delayed Ventricular Septal Rupture Repair After Myocardial Infarction: An Updated Review.

Ventricular septal rupture (VSR) is a rare but serious complication that can occur after myocardial infarction (MI) and is associated with significant morbidity and mortality. The optimal management approach for VSR remains a topic of debate, with considerations including early versus delayed surgery, risk stratification, pharmacological interventions, minimally invasive techniques, and tissue engineering. The pathophysiology of VSR involves myocardial necrosis, inflammatory response, and enzymatic degradation of the extracellular matrix (ECM), particularly mediated by matrix metalloproteinases (MMPs). These processes lead to structural weakening and subsequent rupture of the ventricular septum. Hemodynamically, VSR results in left-to-right shunting, increased pulmonary blood flow, and potentially hemodynamic instability. The early surgical repair offers the advantages of immediate closure of the defect, prevention of complications, and potentially improved outcomes. However, it is associated with higher surgical risk and limited myocardial recovery potential during the waiting period. In contrast, delayed surgery allows for a period of myocardial recovery, risk stratification, and optimization of surgical outcomes. However, it carries the risk of ongoing complications and progression of ventricular remodeling. Risk stratification plays a crucial role in determining the optimal timing for surgery and tailoring treatment plans. Various clinical factors, imaging assessments, scoring systems, biomarkers, and hemodynamic parameters aid in risk assessment and guide decision-making. Pharmacological interventions, including vasopressors, diuretics, angiotensin-converting enzyme inhibitors, beta-blockers, antiplatelet agents, and antiarrhythmic drugs, are employed to stabilize hemodynamics, prevent complications, promote myocardial healing, and improve outcomes in VSR patients. Advancements in minimally invasive techniques, such as percutaneous device closure, and tissue engineering hold promise for less invasive interventions and better outcomes. These approaches aim to minimize surgical morbidity, optimize healing, and enhance patient recovery. In conclusion, the management of VSR after MI requires a multidimensional approach that considers various aspects, including risk stratification, surgical timing, pharmacological interventions, minimally invasive techniques, and tissue engineering.

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

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
