Delayed ventricular septal rupture complicated with ventricular aneurysm in a case of myocardial infarction with non-obstructive coronary arteries.

BACKGROUND: Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a rare cause of heart attack, which may not receive sufficient attention from patients during post-discharge treatment, especially among those with normal coronary angiography results. CASE PRESENTATION: We present the case of a 65-year-old woman who was readmitted to the hospital with ventricular septal rupture (VSR) complicated by ventricular aneurysm, occurring 2 weeks after myocardial infarction. During the initial admission, coronary angiography revealed normal coronary arteries, leading to a diagnosis of MINOCA. Epicardial coronary vasospasm or coronary embolism was considered as potential causes; however, the patient did not adhere to standardized treatment upon initial discharge. The delayed VSR led to a decline in cardiac function but did not result in severe hemodynamic impairment. Following correction of heart failure with medications, the patient underwent percutaneous VSR repair 19 days after diagnosis and was discharged with a favorable recovery. CONCLUSIONS: The occurrence of delayed VSR complicated with ventricular aneurysm in patients with MINOCA is rare, highlighting the possibility of serious complications in MINOCA cases. Both cardioprotective therapies and cause-targeted therapies are essential in the management of patients with MINOCA.

Ventricular apical wall rupture and ventricular aneurysm formation concurrent with ventricular septal dissection and rupture due to ST-segment elevation myocardial infarction: a case report.

The most common mechanical complications of acute myocardial infarction include free-wall rupture, ventricular septal rupture (VSR), papillary muscle rupture and pseudoaneurysm. It is rare for a patient to experience more than one mechanical complication simultaneously. Here, we present a case of ST-segment elevation myocardial infarction (STEMI) complicated with three mechanical complications, including ventricular apical wall rupture, ventricular aneurysm formation and ventricular septal dissection (VSD) with VSR. Cardiac auscultation revealed rhythmic S1 and S2 with a grade 3 holosystolic murmur at the left sternal border. Electrocardiogram indicated anterior ventricular STEMI. Serological tests showed a significant elevated troponin I. Bedside echocardiography revealed ventricular apical wall rupture, apical left ventricle aneurysm and VSD with VSR near the apex. This case demonstrates that several rare mechanical complications can occur simultaneously secondary to STEMI and highlights the importance of bedside echocardiography in the early diagnosis of mechanical complications.

A Surviving Case of Myocardial Infarction with Ventricular Septal Rupture and Ventricular Aneurysm following Gastrointestinal Bleeding.

A 55-year-old man presented to the emergency department with worsening shortness of breath 1 month after a gastrointestinal bleed. He had congestive heart failure, and an electrocardiogram suggested ischemic heart disease involvement. Echocardiography revealed a ventricular septal defect complicated by a left ventricular aneurysm in the inferior-posterior wall. Conservative treatment was started, but hemodynamic collapse occurred on the third day of admission and coronary angiography revealed a revascularizing lesion in the right fourth posterior descending coronary artery. Subsequently, his hemodynamic status continued to deteriorate, even with an Impella CP® heart pump, so ventricular septal defect patch closure and left ventricular aneurysm suture were performed. His condition improved and he was discharged on day 23 of admission and was not readmitted within 6 months after the procedure. Hemodynamic management of ventricular septal defects requires devices that reduce afterload, and clinicians should be aware of the risk of myocardial infarction after gastrointestinal bleeding.

Angiotensin converting enzyme inhibitor and coenzyme Q10 as adjunctive treatment for patients with ventricular septal rupture following late onset myocardial infarction: a case report.

Ventricular Septal Rupture (VSR) is a rare complication of acute myocardial infarction and has a high mortality rate. Surgery is the definitive treatment. However, in hospitals with limited facilities, treating acute myocardial infarction patients with ventricular septal rupture, is challenging. A 74-year-old woman came to the emergency room of Dr. Koesma General Hospital, Tuban, East Java in December, 2019 with late-onset Acute Myocardial Infarction. On the following day, a new holosystolic murmur was heard in the left lower sternal border with palpable thrill. Transthoracic echocardiography showed VSR with severe pulmonary hypertension. This was followed by a drop in the blood pressure to 80/50 mmHg. The blood pressure was dependent on vasopressors until lisinopril and coenzyme Q10 were introduced. After 3 months, the haemodynamics of the patient were stable. This proved that the use of angiotensin-converting enzyme and coenzyme Q10 promotes more energy production, enables tissue healing and leads to balanced remodelling to increase the survival rate in cases of non-surgical treatment.

[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.

Transition to heart transplantation in post-myocardial infarction ventricular septal rupture: a systematic review.

Post-myocardial infarction ventricular septal rupture (MI-VSR) remains a dreadful complication with dismal prognosis. Surgical repair is the primary treatment strategy, whereas the role of heart transplantation (HT) as a primary option in MI-VSR is limited to case reports (CRs). We performed a systematic review of CRs to describe in-hospital mortality, and survival at 6 and 12 months in adult patients with MI-VSR treated with HT as a primary or bailout strategy. We performed a comprehensive search of Web of Science, PubMed, and Ovid Medline. The last search was completed on March 10, 2020. An aggregated score based on the CARE case report guideline was used to assess the quality of the CRs. We included CRs that described adult patients with MI-VSR treated with HT as a primary or bailout strategy. A total of 14 CRs between 1994 and 2015 were included, retrieving and analyzing the characteristics of 17 patients. A total of 12 patients underwent HT, with HT being the primary strategy in 8 patients and a bailout strategy for 4 patients following initial surgical repair, while 5 patients died awaiting HT under mechanical circulatory support (MCS), accounting for the total in-hospital mortality of this series (29%). Regarding long-term outcomes, 6 patients were reported to be alive at 6 months and 1 year after HT, while information was missing in the remaining 6 patients. In conclusion, HT supported by the use of temporary and durable MCS as a bridge to HT could be a feasible primary or bailout strategy to reduce the high in-hospital mortality of patients with MI-VSR.

Transcatheter closure of large postinfarct ventricular septal defect: Initial results of prototype Occlutech® device including the first-in-human.

BACKGROUND: Postinfarct ventricular septal rupture is a serious complication in delayed or failed reperfusion with a grim prognosis. The optimal timing and treatment option remain debatable in the absence of randomized controlled trials. Percutaneous device closure is a well-reported and less invasive treatment option but recent imaging studies indicate that majority of defects are too large to be adequately covered by the currently Conformite Europeenne and Food and Drug Administration approved occluder devices. METHODS: Six patients presented with large and complex postinfarct ventricular septal ruptures, considered unsuitable for the Amplatzer post-infarct ventricular septal defect Occluder, so were treated using the prototype Occlutech® 36 mm PI-VSD occluder, including the first-in-human use. RESULTS: The prototype device was successfully deployed in all patients with satisfactory immediate results and shunt reduction. Three patients (50%) in cardiogenic shock did not survive beyond discharge, of which two were complicated by device dislodgement or embolization. CONCLUSIONS: Percutaneous closure of large postinfarct ventricular septal ruptures is possible using newer device with a wider coverage. Further device refinement is necessary to improve treatment outcomes.

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.

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.

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.

[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.

[Successful Staged Repair of Double Rupture after Acute Myocardial Infarction:Report of a Case].

Double rupture is a very rare, and life-threatening complication after acute myocardial infection (AMI), which defined as the coexistence of any two of the three types of rupture include left ventricular free wall repture (LVFWR), ventricular septal perforation (VSP) and papillary muscule repture (PMR). We report here a case of successful staged repair of double rupture combined LVFWR and VSP. A 77-year-old woman with diagnosis of AMI in the anteroseptal area fell into cardiogenic shock suddenly just before starting coronary angiography. Echocardiography showed left ventricular free wall rupture, then an emergent operation was performed under intraaortic balloon pumping (IABP) and percutaneous cardiopulmonary support (PCPS) assistance using bovine pericardial patch and felt sandwich technique. Intraoperative transesophageal echocardiography revealed ventricular septal perforation on the apical anterior wall. Her hemodynamic condition was stable, therefore we selected a staged VSP repair to avoid surgery on freshly infarcted myocardium. Twenty-eight days after the initial operation, VSP repair was performed using the extended sandwich patch technique via right ventricle incision. Postoperative echocardiography revealed no residual shunt.

Myocardial infarction with non obstructive coronary arteries complicated with ventricular septal rupture: A case report and literature review.

Ventricular septal rupture represents one of the most serious complications after an acute coronary syndrome. Nowadays this condition is rare due to early revascularization, but is still associated with high mortality rate. In this case report, we present an unusual case of a woman suffering an acute myocardial infarction with normal coronary arteries complicated with a ventricular septal rupture, which required surgical correction.

Takostubo syndrome combined with ventricular septal perforation: a case report.

BACKGROUND: The precise clinical features and etiologic basis of Takotsubo syndrome remain unclear, although an association with emotional or stressful triggers has been recognized. Ventricular septal perforation is a very rare life-threatening complication. CASE PRESENTATION: A 77-year-old female patient presented to the hospital with unrelieved chest tightness and shortness of breath. Three months ago, the patient's electrocardiogram revealed ischemic T wave inversion of the anterior wall, along with an increase in myocardial injury markers. There was no evidence of a ventricular septal defect on echocardiography. The patient was admitted to the respiratory department to treat lung lesions. The electrocardiogram demonstrated dynamic changes following admission, and the myocardial markers returned to normal, but the echocardiography revealed a ventricular septal defect. The initial diagnosis was ventricular septal perforation because of myocardial infarction with acute anterior ST-segment elevation. Coronary angiography revealed no abnormalities, but left ventricular angiography revealed an enlarged apex and VSD, with a right ventricular shunt bundle. Later, cardiac MRI revealed an apical ventricular septal defect. Further inquiry of the patient's medical history revealed that her husband died unexpectedly three months ago, and her daughter was seriously injured in a car accident, causing the patient severe emotional distress. Takotsubo syndrome was then determined in conjunction with the patient's medical history, symptoms, signs, and pertinent examinations. Without using a catheter or a surgical procedure, we managed the patient's medical condition. Two weeks later, the patient was discharged with symptoms improved. CONCLUSIONS: Takotsubo syndrome is comparable to an acute myocardial infarction on clinical and electrocardiographic examination in the absence of significant coronary disease. Although ventricular septal perforation is most commonly associated with acute myocardial infarction, it can also happen following Takotsubo syndrome. Takotsubo syndrome complicated by ventricular septal perforation is easily misdiagnosed. The early recognition and management of this condition can avoid or reduce morbidity and mortality.

Ventricular septal rupture: insights into an old disease.

Ventricular septal rupture (VSR) is a serious complication of ST-elevation myocardial infarction (STEMI) and surgery is the reference treatment. We aimed at describing trends in management and mortality during the last four decades and reporting mortality predictors in these patients. We conducted a single-center retrospective study of patients sustaining a VSR from 1981 to 2020. We screened 274 patients and included 265 for analysis. The number of patients decreased over the years: 80, 88, 56, and 50 in each 10-year time span. In-hospital mortality decreased significantly since 1990 (logrank 0.007). The median age was 72.0 years IQR [66-78] and 188 patients (70.9%) were operated on. IABP was used more routinely (p < 0.0001). In-hospital mortality was assessed at 66.8% (177 patients) and main predictors of death were a time from MI to surgery < 8 days HR 2.7 IC95% [1.9-3.8] p < 0.0001, a Killip class > 2 HR 2.5 IC [1.9-3.4] p < 0.0001 and Euroscore 2 > 20 HR 2.4 IC [1.8-3.2] p < 0.0001. A "time from MI to surgery" of 8 days offers the best ability to discriminate between patients with or without mortality. The ability of "Euroscore 2 and Killip" to detect the patients most likely to wait 8 days for surgery was at 0.81 [0.73-0.89] p < 0.0001. Mortality remains high over the years. Euroscore 2, Killip class, and time from MI to surgery are the main mortality predictors. Patients with a Killip < 3 and a Euroscore < 20 should be monitored at least 8 days since MI before being referred to surgery.

Insight into surgical outcomes of post-infarct-ventricular septal defect repair through a 23-year retrospective study-Invited commentary.

The authors present an excellent retrograde analysis of a rare condition of a phenomenal number of cases and their surgical outcomes. A majority of the studies in published literature are anecdotal case reports which are a rare and dreadful entity. A comprehensive countrywide view of the UK National Adult Cardiac Surgery Audit database is presented in this study. This study represents the changing trends in the risk factors, management strategies, and outcomes of ventricular septal rupture for over 23 years in a nutshell.

Ventricular septal rupture after delayed STEMI: A modern management approach.

BACKGROUND: Myocardial infarction associated ventricular septal rupture (VSR) is a potentially catastrophic complication. Though surgical repair remains the definitive treatment, outcomes are poor with high mortality rates.Case and Management: We present the case of a 62-year-old male who presented with a delayed STEMI leading to a VSR and cardiogenic shock. His management strategy included early percutaneous VSR closure and use of an intra-aortic balloon pump and inotropes. This served as a bridge to definitive surgical VSR patch repair while allowing hemodynamic stabilization, end-organ recovery, and myocardial tissue stabilization. CONCLUSION: Mechanical support devices such as intra-aortic balloon pump and Impella combined with percutaneous closure options can serve as a bridge to definitive surgery for VSR. This requires rapid mobilization of a multi-disciplinary structural heart team including advanced imagers, structural interventionalists, and surgeons.

Insertion of durable left ventricular assist device with repair of ischemic ventricular septal rupture.

BACKGROUND: A 63-year-old male who presented with acute anterior wall myocardial infarction with ischemic ventricular septal defect (VSD) required veno-arterial extracorporeal membrane oxygenation support due to a profoundly reduced left ventricular function. METHOD AND RESULS: The VSD was closed with a large bovine pericardial patches. Another Dacron patch was used to close the defect on the anterior wall. The inflow cannula of the left ventricular assist device (LVAD) was sewn to the Dacron patch to secure hemostasis and to maintain the cavity in the left ventricle. The Dacron patch beneath the inflow cuff was then incised, then the LVAD was connected. CONCLUSIONS: we described a case of concomitant insertion of durable LVAD and repair of ischemic VSD utilizing multiple patches.

Ventricular septal defect complicating myocardial infarction: A case of delayed percutaneous transcatheter closure.

A 57-year-old man suffered chest pain during the COVID-19 pandemic, but he delayed medical treatment due to fear of infection. After 4 months, symptoms of chest tightness and shortness of breath appeared. Electrocardiogram (ECG) revealed old myocardial infarction; color sonography and myocardial computed tomography revealed apical myocardial defect. He refused surgery and percutaneous transcatheter closure, and follow-up observation. After 22 months, the symptoms of chest tightness and shortness of breath aggravated. He recovered after percutaneous transcatheter closure, and was discharged. This case shows delayed closure is one of the possible options for patients without severe organ dysfunction or hemodynamic disturbance.

Right ventricular wall dissection complicating myocardial infarction.

Right ventricular wall dissection is extremely rare and can result in dismal clinical outcomes. We report a 68-year-old patient who presented with acute myocardial infarction and was found to have right ventricular wall dissection by ventriculography. At surgery, the infarcted myocardium was excised, and a two-patch technique was used to repair the ventricular septal defect.
