Project description:This is a case of a 59-year-old man presenting with myopericarditis. Over a 2-week period, he developed progressive symptoms and worsening pericardial effusion, leading to cardiac tamponade. Pericardiocentesis revealed hemopericardium, and multidetector computed tomography angiography showed left ventricular free wall rupture. The patient collapsed abruptly, and autopsy confirmed the findings.

Successful infarct exclusion for postinfarction left ventricular free wall rupture.

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.

Left ventricular free wall perforation by a right ventricular pacemaker lead: a case report.

Project description:BackgroundLead perforation is one of the major complications of pacemaker implantation, but cases of right ventricular (RV) lead perforation through the septum and left ventricle are rarely reported. We described a rare case of left ventricular (LV) free wall perforation by an RV lead and the management of this complication.Case summaryAn 84-year-old man was admitted with a dual-chamber pacemaker due to pacing failure caused by an RV lead fracture. New lead implantation was performed on the next day, but pacing failure occurred again on the second post-operative day (POD). We found the lead perforation on the fluoroscopy during temporary pacemaker insertion. Computed tomography scan and transthoracic echocardiogram showed that the added lead perforated through both the septum and LV free wall. A new lead was inserted on the fourth POD, and an off-pump open chest surgery for extraction of the penetrating lead was performed uneventfully on the 20th POD.DiscussionWe considered that some features of the lead (SelectSecure 3830-69, Medtronic) may be related to this complication, as the lead was very thin, had a non-retractable bare screw and was inserted with a dedicated delivery catheter. We have to be careful when performing implantation of this kind of lead to avoid such a rare complication.

Meta-analysis of surgical treatment for postinfarction left ventricular free-wall rupture.

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.

Whole human genome expression analysis on left ventricular free wall heart tissue samples

Project description:Human left ventricular free wall heart tissue was obtained from end-stage heart failure patients at the moment of heart transplantation Left ventricular free wall samples were also obtained from healthy hearts of organ donors, which were not used for transplantation due to size mismatch with available recipients.

Cardiac CT for intraseptal pseudoaneurysm: impending double rupture of ventricular septum and left ventricular free wall.

Project description:A 71-year-old woman presented at our hospital with chest discomfort. Cardiac CT showed an impending double rupture; an intraseptal pseudoaneurysm had ruptured into the right ventricle, while the left ventricular free wall remained intact at this stage. After admission, the patient fell into cardiogenic shock. Emergency surgery was performed. The intraoperative findings included a double rupture of the ventricular septum and the left ventricular free wall. Double rupture is a rare but fatal complication of myocardial infarction. Early diagnosis is essential. Recently, cardiac CT has emerged as a valuable tool for patients with possible ischaemic disease. In this case, enhanced cardiac CT showed an impending double rupture of junctional-type. The static and dynamic images of intraseptal pseudoaneurysm by two-dimensional (2-D) CT, 3-D CT and 4-D CT presented here provide insights into the mechanisms behind, and the pathophysiology of, double ruptures. They also demonstrate the significance of cardiac CT for evaluating ischaemic heart disease.

Spontaneous Coronary Artery Dissection Complicated by Left Ventricular Free Wall Rupture in Turner Syndrome

Project description:A 38-year-old with Turner syndrome presented with acute myocardial infarction due to multivessel spontaneous coronary artery dissection (SCAD) complicated by left ventricular free wall rupture. Conservative management for SCAD was pursued. She underwent sutureless repair for an oozing-type left ventricular free wall rupture. SCAD has not been previously reported in Turner syndrome.
