Project description:ImportanceVentricular septal rupture (VSR) is a rare but life-threatening mechanical complication of acute myocardial infarction associated with high mortality despite prompt treatment. Surgery represents the standard of care; however, only small single-center series or national registries are usually available in literature, whereas international multicenter investigations have been poorly carried out, therefore limiting the evidence on this topic.ObjectivesTo assess the clinical characteristics and early outcomes for patients who received surgery for postinfarction VSR and to identify factors independently associated with mortality.Design, setting, and participantsThe Mechanical Complications of Acute Myocardial Infarction: an International Multicenter Cohort (CAUTION) Study is a retrospective multicenter international cohort study that includes patients who were treated surgically for mechanical complications of acute myocardial infarction. The study was conducted from January 2001 to December 2019 at 26 different centers worldwide among 475 consecutive patients who underwent surgery for postinfarction VSR.ExposuresSurgical treatment of postinfarction VSR, independent of the technique, alone or combined with other procedures (eg, coronary artery bypass grafting).Main outcomes and measuresThe primary outcome was early mortality; secondary outcomes were postoperative complications.ResultsOf the 475 patients included in the study, 290 (61.1%) were men, with a mean (SD) age of 68.5 (10.1) years. Cardiogenic shock was present in 213 patients (44.8%). Emergent or salvage surgery was performed in 212 cases (44.6%). The early mortality rate was 40.4% (192 patients), and it did not improve during the nearly 20 years considered for the study (median [IQR] yearly mortality, 41.7% [32.6%-50.0%]). Low cardiac output syndrome and multiorgan failure were the most common causes of death (low cardiac output syndrome, 70 [36.5%]; multiorgan failure, 53 [27.6%]). Recurrent VSR occurred in 59 participants (12.4%) but was not associated with mortality. Cardiogenic shock (survived: 95 [33.6%]; died, 118 [61.5%]; P < .001) and early surgery (time to surgery ≥7 days, survived: 105 [57.4%]; died, 47 [35.1%]; P < .001) were associated with lower survival. At multivariate analysis, older age (odds ratio [OR], 1.05; 95% CI, 1.02-1.08; P = .001), preoperative cardiac arrest (OR, 2.71; 95% CI, 1.18-6.27; P = .02) and percutaneous revascularization (OR, 1.63; 95% CI, 1.003-2.65; P = .048), and postoperative need for intra-aortic balloon pump (OR, 2.98; 95% CI, 1.46-6.09; P = .003) and extracorporeal membrane oxygenation (OR, 3.19; 95% CI, 1.30-7.38; P = .01) were independently associated with mortality.Conclusions and relevanceIn this study, surgical repair of postinfarction VSR was associated with a high risk of early mortality; this risk has remained unchanged during the last 2 decades. Delayed surgery seemed associated with better survival. Age, preoperative cardiac arrest and percutaneous revascularization, and postoperative need for intra-aortic balloon pump and extracorporeal membrane oxygenation were independently associated with early mortality. Further prospective studies addressing preoperative and perioperative patient management are warranted to hopefully improve the currently suboptimal outcome.

Project description:Postinfarction ventricular septal rupture remains a lethal complication of acute myocardial infarction. Percutaneous closure is feasible and may provide an alternative treatment option to surgical repair, particularly in the nonacute phase. Transcatheter closure of postinfarction ventricular septal rupture using innovative custom-made devices may be a promising alternative to high-risk surgery.

Project description:The mortality of postinfarction left ventricular free wall rupture is still high. Several surgical techniques have been used for repairing such ruptures. Here, we describe using an infarction exclusion technique to successfully treat a case of a blow-out type postinfarction left ventricular free wall rupture. This technique has frequently been used for repairing postinfarction ventricular septal perforation. In this case, infarcted myocardial tearing was prevented, and complete haemostasis was achieved by infarct exclusion.

Project description:Introduction. Dissection of the myocardium is a rare form of cardiac rupture, caused by a hemorrhagic dissection among the spiral myocardial fibers, its diagnosis is rarely established before the operation or death, and extremely few cases have been reported in the literature and none of these cases seem to have a history of previous cardiac surgery which makes our report unique. Case Presentation. A 61-year-old female patient was admitted into the emergency room with complaints of progressive chest pain for 2 days. She had a history of second time prosthetic aortic valve replacement and was under anticoagulation therapy. She was diagnosed with an acute inferoposterior myocardial infarction and underwent emergency coronary angiography revealing spontaneous recanalization of the right coronary artery. During the follow-up, she developed cardiogenic shock and a new occurring systolic ejection murmur. Transthoracic echocardiography showed a left ventricular free wall rupture; then, she was taken in for emergency surgery. During the operation, a rupture zone and a wide intramyocardial dissecting area were detected. Intraventricular patch repair technic with autologous pericardial patch was used to exclude the ruptured area. Following the warming period, despite adequate hemostasis, hemorrhage around suture lines progressively increased, leading to the patient's death. Conclusion. Pericardial adhesions might contain left ventricular rupture leading to intramyocardial dissection.

Project description:BackgroundLeft ventricular free-wall rupture (LVFWR) is one of the most lethal complications after acute myocardial infarction (AMI). The optimal therapeutic strategy is controversial. The current meta-analysis sought to examine the outcome of patients surgically treated for post-AMI LVFWR.MethodsA comprehensive literature review was performed to identify articles reporting outcomes of subjects who underwent LVFWR surgical repair. The primary endpoint was operative mortality. A meta-analysis was performed to assess the associations of predefined variables of interest and clinical prognosis.ResultsOf the 3132 retrieved articles, 11 nonrandomized studies, enrolling a total of 363 patients, fulfilled the inclusion criteria and were included in this analysis. The mean age of patients was 68 years. The operative mortality rate was 32% (n = 115). Meta-analysis revealed reduced operative risk in patients with oozing type rupture, as compared to blowout type (risk ratios [RR]: 0.47; 95% confidence interval [CI]: 0.33-0.67; p < .0001); RR was also significantly reduced in subjects in whom LVFWR was treated with sutureless technique, as compared to those undergoing sutured repair (RR: 0.59; 95% CI: 0.41-0.83; p = .002). Increased risk of operative mortality was demonstrated in patients who required postoperative extracorporeal membrane oxygenation (ECMO) support (RR: 2.39; 95% CI: 1.59-3.60; p < .0001).ConclusionsSurgical treatment of postinfarction LVFWR has a high operative mortality rate. Blowout rupture, sutured repair and postoperative ECMO support are factors associated with increased risk of operative mortality.

Project description:Ventricular septal rupture is a rare and potentially fatal complication of transmural myocardial infarction. Early identification utilising transthoracic echocardiography significantly improves long term outcomes in these patients. We report on a case of a 77-year-old male who presented with signs and symptoms of cardiac failure and a loud systolic murmur. The patient underwent an initial point-of-care ultrasound which revealed evidence of a transmural myocardial infarction and a high suspicion of an apical ventricular septal rupture. A complete transthoracic echocardiogram confirmed the septal rupture diagnosis and the patient subsequently underwent surgical repair of the ventricular rupture. This case highlights the role of echocardiography in decreasing adverse outcomes in patients with ventricular septal rupture.

Project description:The development of a myocardial infarction ventricular septal rupture is a rare fatal complication, and the surgical repair is the treatment of choice. In most of the scenarios, the operation will be done as an emergency procedure that carries high mortality. Prognosis of these patients depends on prompt echocardiographic diagnosis and the proactive medical and surgical therapy. More recently, various options have been put forward including the timing for surgery, percutaneous closure devices, and the improved outcome with initial stabilization with medical treatment including mechanical support. In this retrospective case series, we are presenting the management of these patients who presented us in different clinical scenarios and trying to identify the risks for the poor outcome and to formulate a strategy to improve the outcome.

Project description:Advanced age and female sex are known risk factors for ventricular wall rupture during open-heart procedures. We present the case of an 83-year-old female patient with an intraoperative traumatic right ventricular free wall rupture during an aortic valve replacement procedure. Pledgetted interrupted sutures reinforced with large pieces of mediastinal fat were used for rupture repair. After 6 months, the patient was readmitted with the diagnosis of a retrosternal mediastinal mass and clinical signs of cardiac tamponade that required reoperation.

Project description:BackgroundThe use and utility of novel oral anticoagulants has been increasing in clinical practice due to their relatively lower incidence of side effects such as intracranial haemorrhage, particularly in the elderly, when compared with vitamin K antagonists. Rivaroxaban is a factor Xa and prothrombinase inhibitor indicated for stroke and venous thromboembolism prophylaxis in non-valvular atrial fibrillation as well as treatment of venous thromboembolism.Case summaryA patient with history of paroxysmal atrial fibrillation on Rivaroxaban presented with generalized malaise, lightheadedness, and dizziness. The patient was found to be in profound cardiogenic shock despite unremarkable cardiac enzymes. Electrocardiogram revealed rate controlled atrial fibrillation and T-wave inversions in the inferolateral leads without associated electrical alternans. Bedside echocardiogram revealed a large pericardial effusion consistent with cardiac tamponade physiology. Following anticoagulation reversal, the patient underwent urgent pericardiocentesis yielding haemorrhagic fluid, with subsequent improvement in haemodynamic status. Despite the presence of retroperitoneal lymphadenopathy on previous computed tomography of the abdomen and concern for underlying malignant effusion secondary to lymphoma, cytology of the fluid revealed no evidence of malignant cells and follow-up flow cytometry and bone marrow biopsy were unremarkable.DiscussionWhile hemopericardium is not listed as a known side effect of Rivaroxaban, previous cases of hemopericardium secondary to Rivaroxaban have been described in the literature secondary to pre-disposing risk factors including CYP450 drug interactions or cardiac device implantations. In this case, the patient experienced a spontaneous hemopericardium on Rivaroxaban without any previously elucidated risk factors or evidence of malignancy.
