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.

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.

Spontaneous Coronary Artery Dissection (SCAD) Complicated With Post-Infarction Ventricular Septal Rupture and a Comparative Review on Mechanical Complications Related With SCAD.

Spontaneous coronary artery dissection (SCAD) is not uncommon but remains arguably an under-diagnosed etiology for acute coronary syndrome (ACS). It occurs predominantly in young-to-middle aged women who have no or few traditional atherosclerotic cardiovascular disease risk factors. Post-infarction mechanical complications are a dreaded outcome of ACS. However, very few case reports describe these mechanical complications related to SCAD. Unsuccessful revascularization is a particular concern for patients presenting with SCAD-induced ACS, which can increase the risk for certain mechanical complications. We present a case of a middle-aged woman who presented with anterior ST-segment elevation myocardial infarction and was found to have SCAD of left anterior descending coronary artery. Two attempts at revascularization were unsuccessful. Thereafter, her clinical course was complicated by the development of heart failure as a result of a reduced ejection fraction and a left ventricular pseudoaneurysm. Importantly she also suffered a ventricular septal rupture necessitating surgical intervention. Fortunately, our patient had a favorable longer-term outcome. Current literature, including five published case reports on SCAD complicated by mechanical complications are reviewed. Clinicians must remain aware of post-infarction mechanical complications in patients with high-risk and non-revascularized SCAD.

Frequency Of Ventricular Septal Rupture As A Complication Of Acute St-Elevation Myocardial Infarction In Patients Presenting To A Tertiary Care Hospital.

Background: Nearly one-third of the world's population dies from cardiovascular disorders, the majority of which are caused by stroke and coronary artery problems and 80 percent of these fatalities occur in impoverished countries. This study was conducted to determine the frequency of ventricular septal rupture in patients with acute ST-elevation myocardial infarction presenting to cardiology unit Hayatabad Medical Complex Peshawar. Methods: This was descriptive cross sectional research study at the Department of Cardiology, MTI-Hayatabad Medical Complex, Peshawar, from January to July 2020. Detailed history was obtained including duration of symptoms, co-morbidities present and occupation. A thorough clinical examination was done for signs of heart failure and ventricular septal rupture. Patients' demographics, clinical and laboratory parameters were recorded on a pro forma. All the data was analyzed statistically by using SPSS version 24.0. Results: A total of 179 patients were included in our study. Ventricular Septal Rupture (VSR), was recorded in 7 (3.9%) patients having Acute ST elevation of MI. In our study age, obesity, reperfusion therapy, location of MI and history of previous shock were observed to be non significantly (p˂0.05) associated with high incidence of Ventricular Septal Rupture in patients having Acute ST elevation of MI. Conclusion: According to our findings, individuals with PI-VSR have a significant risk of acute-phase death. Furthermore, a significant incidence of acute-phase fatalities has been related to female gender and severe cardiac failure upon admission.

Point-of-Care Ultrasound Diagnosis of Ventricular Septal Rupture Post Myocardial Infarction: A Case Report.

BACKGROUND: Ventricular septal rupture (VSR) is a rare but life-threatening complication of ST-elevation myocardial infarction. Point-of-care ultrasound (POCUS) is a rapid, noninvasive imaging modality that is easily accessible and highly effective in diagnosing VSR in the emergency department (ED) setting. CASE REPORT: A 73-year-old man with a history of type II diabetes mellitus and hypertension presented with complaints of intermittent chest pain for 48 h that had since become constant, associated with diaphoresis and shortness of breath. Physical examination was notable for shock and a new, grade V/VI systolic murmur. An electrocardiogram showed evidence of an inferior ST-elevation myocardial infarction (MI) with associated Q waves. POCUS revealed a large ventricular septal rupture with new ventricular septal defect and associated left-to-right shunting. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: POCUS in the ED setting is an effective and rapid tool for elucidating the etiology of various shock states. Emergency physicians should be aware of this particular case, as POCUS may help identify MI-related complications, including post-myocardial infarction VSR, that may necessitate surgical intervention as opposed to coronary reperfusion procedures.

Inferior ST-Segment Elevation Can Predict In-Hospital Mortality in Patients with Anterior Myocardial Infarction Complicated by Ventricular Septal Rupture.

Background: Electrocardiogram (ECG) findings in patients with anterior wall myocardial infarction (MI) complicated by ventricular septal rupture (VSR) have rarely been studied. Methods: We conducted a single-center retrospective study among patients with anterior MI complicated by VSR over the past ten years. The presence of ST-segment elevation (STE) in inferior leads and new onset of complete right bundle branch block (RBBB) on ECG were studied for the prediction of in-hospital mortality. Results: Among the 85 patients enrolled, 45 (52.9%) were male, with a median age of 70 years. Sixty-five patients (76.5%) died in the hospital, and the remaining 20 patients (23.5%) had improved conditions and were discharged. Inferior STE was present in 35 patients (41.2%), including 32 patients in the death group and 3 patients in the survival group (P = 0.005). New-onset RBBB was present in 25 patients (29.4%), with 22 patients in the death group and 3 patients in the survival group (P = 0.103). Multivariate logistic regression showed that inferior STE was an independent predictor of in-hospital death in patients with anterior MI and VSR (OR: 14.488; 95% CI: 1.708-122.887; P = 0.014). Conclusions: In patients with anterior MI complicated by VSR, inferior STE was associated with a higher risk of in-hospital mortality.

Delayed Presentation of Inferior STEMI Complicated by Ventricular Septal Rupture: An Indirect Consequence of the COVID-19 Pandemic.

The COVID-19 pandemic has adversely impacted healthcare delivery. An indirect consequence of the rational fear of contracting the virus is delayed medical attention for life threatening conditions. We present the case of inferior ST elevation myocardial infarction leading to the rare complication of a ventricular septal rupture reflecting transmural infarction. COVID hesitancy caused a 48-hour delay in seeking medical attention after symptom onset. We also discuss the use of MRI to guide decision for timing of VSD repair in an otherwise asymptomatic patient post-revascularization.

Simultaneous Left Ventricular Aneurysm and Ventricular Septal Rupture Complicating Delayed STEMI Presentation: A Case-Based Review of Post-MI Mechanical Complications Amid the COVID-19 Pandemic.

Amid the coronavirus disease 2019 (COVID-19) pandemic, there is an unprecedented increase in public avoidance of hospitals predominantly driven by fear of contracting the virus. Recent publications highlight a re-emergence of rare post-myocardial infarction complications. While mechanical complications are infrequent in the era of primary percutaneous coronary intervention, they are associated with high mortality rates. The concurrent occurrence of mechanical complications such as left ventricular aneurysm and ventricular septal rupture is an extremely rare entity. We hereby delineate a unique case of a 53-year-old Caucasian male who underwent successful concomitant closure of a ventricular septal rupture, left ventricular aneurysmectomy, and 3-vessel coronary artery bypass grafting. Due to a delayed initial presentation owing to the patient's fear of contracting COVID-19, the surgery was carried out 3 months after the myocardial infarction. His postoperative evaluation confirmed normal contractility of the left ventricle and complete closure of the ventricular septal rupture. Six months postoperatively, the patient continues to do well. We also present a literature review of the mechanical complications following delayed presentation of myocardial infarction amid the COVID-19 pandemic. This article illustrates that clinicians should remain cognizant of these extremely rare but potentially lethal collateral effects during the ongoing global public-health challenge. Furthermore, it highlights a significant concern regarding the delay in first medical contact due to the reluctance of patients to visit the hospital during the COVID-19 pandemic.

Delayed surgery after mechanical circulatory support for ventricular septal rupture with cardiogenic shock.

OBJECTIVES: The effectiveness of delayed surgery for ventricular septal rupture (VSR) following myocardial infarction (MI) in patients with cardiogenic shock remains unknown. We aimed to investigate the outcomes of delayed surgery following mechanical circulatory support for patients in cardiogenic shock after VSR. METHODS: We reviewed 8 patients with post-MI VSR and cardiogenic shock who underwent delayed surgery at our institution between July 2015 and November 2017. Surgery was delayed until haemodynamic stabilization and improved organ ischaemia were achieved by initiating intra-aortic balloon pumping with or without veno-arterial extracorporeal membrane oxygenation (ECMO). We investigated the operative mortality, morbidity and late survival. RESULTS: All 8 patients had preoperative intra-aortic balloon pump support, and 5 had additional veno-arterial ECMO support. Emergency repair was successfully avoided in all cases. The median time from the onset of MI to operation was 7.1 (3.7-9.9) days, and that from the diagnosis of VSR to operation was 1.9 (1.3-2.3) days. The operative mortality was 12.5%, and complications related to mechanical circulatory support occurred in 1 case (12.5%). The 2-year survival rate was 62.5%. CONCLUSIONS: A combination of preoperative mechanical circulatory support and delayed surgery may improve the outcomes of patients with post-MI VSR, which was complicated by cardiogenic shock. The key to a better surgical outcome may be delaying the surgery for improving end-organ perfusion. This requires further investigation, especially for determining the optimal duration of support.

Efficacy of extracorporeal membrane oxygenation before surgery of a post-infarction ventricular septal rupture in cardiogenic shock.

A 73-year-old man with an acute myocardial infarction experienced severe cardiogenic shock due to an inferior ventricular septal rupture with a massive left-to-right shunt. Emergency surgery was considered a too high mortality risk. The patient was implanted with an extracorporeal membrane oxygenation system as a bridge to surgery. On the seventh day after admission, the ventricular septal defect was successfully repaired. Our case study demonstrates that extracorporeal membrane oxygenation could be an option in cases of ventricular septal rupture as a bridge for stabilizing patients.

Impella support as a bridge to scheduled surgical repair of ventricular septal rupture.

We studied the experience of a 69-year-old woman with acute decompensated heart failure due to post-infarction ventricular septal rupture. She received mechanical hemodynamic support by Impella 2.5 (Abiomed, Danvers, MA, USA), percutaneous axial-flow left ventricular assist device, which improved intra-cardiac pressure, maintaining end-organ function. She was successfully bridged to the scheduled surgical repair of ventricular septal rupture following the 9-day Impella support and discharged on foot on the 32nd day. Impella might be a useful mechanical circulatory support device as a bridge tool to the scheduled surgical repair of ventricular septal rupture if used with careful daily management to prevent device-related comorbidities.

[Analysis of mortality relative factors in patients with ventricular septal rupture complicating myocardial infarction].

Objective: To examine the mortality rate and relative factors associate with ventricular septal rupture in myocardial infarction patients. Methods: A total of 51 patients who suffered from myocardial infarction complicating with ventricular septal rupture received operative procedures between January 2005 and December 2018 in Department of Cardiac Surgery, Beijing Anzhen Hospital, Capital Medical University, were retrospectively analyzed. There were 34 males and 17 females, with an age of (63±8) years (range: 44 to 82 years). The time between ventricular septal rupture and surgical procedure was (44±39) days (range: 3 to 187 days). The t test and χ(2) test were used for univariate analysis, Logistics regression model was used for multivariate analysis of in-hospital mortality relative factors. Results: There were 8 patients dead in hospital, 43 patients survived, the overall mortality rate was 15.7% in hospital. The post-operation mortality rate was 2/3 of who suffered ventricular septal rupture and underwent operation within 1 week, but it's markedly decreased to 6.5% if the time over 4 weeks. Univariate analysis showed that renal failure before operation, creatinine before operation, left ventricular ejection fraction, cardiac function (New York Heart Association) grade Ⅳ, severe tricuspid regurgitation, dialysis post-operation, creatinine of the first day of post-operation, the time between and operation more than 4 weeks were in-hospital mortality relative factors. Multivariate analysis reflected that advanced age (OR=1.32, 95%CI: 1.05 to 1.75, P=0.033), cardiac function grade Ⅳ (OR=2.25, 95%CI: 1.62 to 2.82, P=0.003), severe tricuspid regurgitation (OR= 1.82, 95%CI: 1.31 to 2.43, P=0.001), renal failure before operation (OR=1.78, 95%CI: 1.26 to 2.32, P=0.015), the time between ventricular septal rupture and operation less than 1 week (OR=2.50, 95%CI: 1.52 to 2.98, P=0.012), were independent in-hospital mortality relative factors. Conclusions: The surgery operation is an effective way to deal with ventricular septal rupture combined with myocardial infarction. The independent relative factors of in-hospital mortality are advanced age, cardiac function grade Ⅳ, renal failure before operation, severe tricuspid regurgitation, the time between ventricular septal rupture and operation less than 1 week.

Improving hemodynamics - Prolonged intra-aortic balloon pump usage in posterior ventricular septal rupture with right ventricle dysfunction.

The associated mortality and morbidity of posterior ventricular septal rupture (VSR) is quite high increasing to almost 80% due to severe right ventricle dysfunction and pulmonary artery hypertension. Herein, we present a case of posterior VSR due to inferior wall myocardial infarction who underwent surgery. Premature removal of intra-aortic balloon pump (IABP) led to hemodynamic deterioration and he was salvaged with prolonged and prompt re-institution of IABP. This case also highlights the importance of IABP in right ventricle failure.

The role of perioperative cardiorespiratory support in post infarction ventricular septal rupture-related cardiogenic shock.

BACKGROUND: Current guidelines recommend emergency surgical correction in patients with post infarction ventricular septal rupture (PIVSR), but patients with multiorgan failure are commonly managed conservatively because of high surgical risk. We assessed characteristics and outcomes of operated PIVSR patients with or without the use of short-term ventricular assist devices (ST-VADs). We also assessed the impact of a ST-VAD on the performance of surgery. METHODS: We retrospectively analysed all consecutive patients with PIVSR between January 2004 and May 2017. Baseline clinical characteristics, use of ST-VAD and performance of surgery during admission were assessed. The main outcome measured was in-hospital mortality. RESULTS: A total of 28 patients were included. Mean age was 69.2 years. Most patients (20/28, 71.4%) underwent surgical repair. ST-VADs were used in 11/28 patients (39.3%). This percentage progressively increased across the study period, from 22.2% (2/9) in 2004-2011 to 58.3% (7/12) in 2015-2017 (p=0.091). Patients undergoing ST-VAD use had poorer INTERMACS status, higher values of creatinine, lactate and alanine aminotransferase and lower left ventricular ejection fraction as compared with operated patients without support. In-hospital mortality did not differ according to the use of ST-VADs in operated patients (27.3% without ST-VAD vs. 22.2% with ST-VAD, p=0.604). All five patients undergoing early preoperative venoarterial extracorporeal membrane oxygenator support and delayed surgery survived at hospital discharge. CONCLUSIONS: ST-VAD use increased in patients with PIVSR. Despite a higher risk profile in operated patients undergoing ST-VAD use, mortality was not significantly different in these patients. Early preoperative venoarterial extracorporeal membrane oxygenation should be considered for very high risk PIVSR patients.

Successful occlusion of ventricular septal rupture in myocardial infarction under the guidance of echocardiography.

INTRODUCTION: The traditional treatment of myocardial infarction with ventricular septal rupture is surgical treatment. For the elderly patients with cardiac insufficiency, surgical treatment is very risky. The successful treatment of this case by interventional occlusion is a new method. No relevant literature reports have been found. CASE: A 77-year-old man with a past medical history of old myocardial infarction presented to the physician with sudden onset of palpitation and shortness of breath. Echocardiography showed thinning of the interventricular septum near the apex and bulging toward the right ventricular side with "paradoxical motion", on which a rupture of about 8 mm in diameter was seen. CDFI: left ventricular blood shunted to the right ventricle through the rupture.Echocardiographic diagnosis: old left ventricular anteroseptal myocardial infarction with ventricular septal rupture. Due to the older age of the patient and reduced left ventricular function, surgical repair of the ventricular septal rupture site was more difficult. After multidisciplinary discussion, it was agreed that the patient could not afford thoracotomy and was not suitable for thoracotomy, and echocardiography guided interventional occlusion of the ruptured interventricular septum could be performed. CONCLUSION: Transesophageal echocardiography-guided interventional occlusion of myocardial infarction with ventricular septal rupture in elderly patients with cardiac insufficiency is a new attempt, the successful treatment of this case shows that this method is feasible, for some patients is an appropriate treatment.

Transcatheter Closure of Post Infarction Subacute Ventricular Septal Defect: A Case Report.

Ventricular septal rupture (VSR) is an uncommon but lethal complication of acute myocardial infarction (MI). Although early surgical closure is the treatment of choice, hospital mortality after emergency surgery remains high. Transcatheter closure of post myocardial infarction ventricular septal defect (PIVSD) has emerged as a potential treatment option in selected cases. Herein, we report a case present in AFC Health FORTIS Heart Institute, Khulna, Bangladesh on 10 February 2017 of sub acute post-MI VSR that was successfully closed using an Amplatzerseptal occlude (ASD) device. The patient had undergone primary percutaneous coronary intervention (PCI) 15 days earlier in the setting of acute MI.

Profile and Outcomes of Surgical Treatment for Ventricular Septal Rupture in Patients With Shock.

BACKGROUND: The outcomes of surgical treatment of ventricular septal rupture (VSR) complicating acute myocardial infarction are worse in patients with cardiogenic shock. This study aimed to identify clinical characteristics and outcomes in patients with VSR presenting with cardiogenic shock. METHODS: A retrospective analysis was performed in 105 consecutive VSR patients, 71 with cardiogenic shock (67.6%) and 34 without cardiogenic shock (32.4%), who underwent surgical treatment in the Department of Adult Cardiac Surgery of Fuwai Hospital between January 2002 and December 2017. Baseline characteristics and outcomes in patients with VSR with and without cardiogenic shock were assessed. RESULTS: There were no differences in hypertension, diabetes, history of myocardial infarction, body mass index, or location of VSR between patients with and without cardiogenic shock. The size of VSR was larger in patients with cardiogenic shock than in those without (18.2 ± 8.1 mm vs 14.0 ± 7.8 mm; P = .013). Intraaortic balloon pump was required more in patients with cardiogenic shock before operation (39 [68.4%] vs 1 [5.0%]; P < .001]. More emergency surgeries were performed in the cardiogenic shock group (21 [29.6%] vs 3 [8.8%]; P = .018). There were 3 in-hospital deaths among patients with VSR with cardiogenic shock. After 76.56 ± 47.78 months of follow-up, only 2 noncardiac deaths were documented. CONCLUSIONS: The larger the ventricular septal rupture is, the more prone patients are to develop cardiogenic shock. Surgical treatment outcomes for VSR with cardiogenic shock are satisfactory.
