The commonest cause of blunt cardiac injuries is from traffic accidents followed by violent falls, sport activities, accidents or a fight but rupture of the heart is rare and lethal. The precise incidence of cardiac injury after a blunt chest trauma is unknown as rates vary greatly in the literature from between 7% and 76% of cases. Autopsy studies have shown that the right ventricle is the most frequently ruptured, followed by the left ventricle, right atrium, intraventricular septum, left atrium and interatrial septum with decreasing frequency...

A young woman presented with fulminant heart failure. Transthoracic echocardiography revealed severe left ventricular dysfunction with a mass adjacent to the basal anterior wall, near the left ventricular outflow tract (LVOT). The cause of the acute heart failure and mass was unclear. Transesophageal echocardiography, with contrast, and cardiac magnetic resonance imaging findings were consistent with thrombus near the LVOT. Cardiac biopsy suggested giant cell myocarditis. The patient was treated with anticoagulation, steroids, and heart failure medications with resolution of the thrombus...

Background: Spinal cord infarction (SCI) after epidural anesthesia is quite rare. Although most cases of perioperative SCI are associated with aortic, cardiac, or spinal surgery, and/or abnormal preoperative conditions, such as spinal stenosis or hypercoagulopathy, intraoperative events, such as severe hypotension or epidural puncture and catheterization, can be contributory factors. Case presentation: A 52-year-old male was underwent laparoscopic gastrectomy. Before induction of general anesthesia, an epidural catheter was placed without any problems...

BACKGROUND: The aim of this study was to examine the association between abnormal morphology of the proximal aorta and aortic stenosis (AS) progression rate. The main hypothesis was that morphologic changes of the proximal aorta, such as effacement of the sinotubular junction (STJ), result in increased biomechanical stresses and contribute to calcification and progression of AS. METHODS: Between 2010 and 2012, 426 patients with mild to moderate AS were included in this study...

OBJECTIVE: Diastolic dysfunction is common in hypertrophic cardiomyopathy (HCM) and hypertensive heart disease (HHD), but its relationships with left ventricular (LV) parameters have not been well studied. Our objective was to assess the relationship of various measures of diastolic function, and maximum left ventricular wall thickness (MLVWT) and left ventricular mass index (LVMI) in HCM, HHD and normal controls using cardiac magnetic resonance imaging (CMR). We also assessed LV parameters and diastolic function in relation to late gadolinium enhancement (LGE) and right ventricular (RV) hypertrophy in HCM...

This article reviews important features to improve the diagnosis of congenital heart disease (CHD) by applying ultrasound in prenatal cardiac screening. As low and high-risk pregnancies for CHD are subject to routine obstetric ultrasound, the diagnosis of structural heart defects represents a challenge that involves a team of specialists and subspecialists on fetal ultrasonography. In this review, the images highlight normal anatomy of the heart as well as pathologic cases consistent with cardiac malposition and isomerism, septal defects, pulmonary stenosis/atresia, aortic malformations, hypoplastic left ventricle, conotruncal anomalies, tricuspid dysplasia, and Ebstein's anomaly, and univentricular heart, among other congenital cardiovascular defects...

BACKGROUND AND OBJECTIVE: Studies conducted across the world have reported that the rates of major adverse cardiac events (MACE) following the use of bioresorbable vascular scaffolds (BVS) are comparable to that noted with traditional drug eluting stents (DES). However, there is limited data on the immediate and medium-term clinical outcomes following the use of the Absorb BVS (Abbott Vascular, Santa Clara, SA) in the Indian context. This study was conducted to determine real-world evidence on the immediate and medium-term clinical outcomes in all patients undergoing percutaneous coronary intervention (PCI) with the Absorb BVS...

Pediatric cardiomyopathies are a group of myocardial diseases with complex taxonomies. Cardiomyopathy can occur in children at any age, and it is a common cause of heart failure and heart transplantation in children. The incidence of pediatric cardiomyopathy is increasing with time. They may be associated with variable comorbidities, which are most often arrhythmia, heart failure, and sudden death. Medical imaging technologies, including echocardiography, cardiac magnetic resonance, and nuclear cardiology, are helpful in reaching a diagnosis of cardiomyopathy...

The prediction of cancer therapeutics-related cardiac dysfunction (CTRCD) is an essential aspect of care for individuals who receive potentially cardiotoxic oncologic treatments. Certain clinical risk factors have been described for incident CTRCD, and measurement of left ventricular (LV) longitudinal strain by speckle tracking 2-dimensional echocardiography (2DE) is the best-validated myocardial mechanical imaging assessment to detect subtle changes in LV function during cancer treatment. However, the direct integration of clinical and imaging risk factors to predict CTRCD has not yet been extensively examined...

BACKGROUND: Non-invasive approaches to investigate myocardial efficiency can help track the progression of heart failure (HF). This study evaluates the repeatability and reproducibility of 11 C-acetate positron emission tomography (PET) imaging of oxidative metabolism. METHODS AND RESULTS: Dynamic 11 C-acetate PET scans were performed at baseline and followup (47 ± 22 days apart) in 20 patients with stable HF with reduced ejection fraction. Two observers blinded to patients' clinical data used FlowQuant ® to evaluate test-retest repeatability, as well as intra- and inter-observer reproducibility of 11 C-acetate tracer uptake and clearance rates, for the measurement of myocardial oxygen consumption (MVO 2 ), myocardial external efficiency (MEE), work metabolic index (WMI), and myocardial blood flow...

BACKGROUND: Patients with heterotaxy syndrome (HS) often have asymptomatic malrotation. There is a lack of consensus regarding the management of these patients, particularly in patients with complex congenital heart disease (CHD). We sought to describe the prevalence of malrotation and incidence of volvulus in a population of patients with complex CHD and to identify the impact of malrotation on morbidity and mortality following cardiac surgery. METHODS: We performed a retrospective review of all patients with HS and complex CHD who required cardiac surgery in the first year of life at a single center between October 1995 and September 2015...

Clinical surveillance of acute heart transplantation rejection requires repeated invasive endomyocardial biopsies and noninvasive diagnostic techniques are desperately needed. It is acknowledged that T lymphocyte infiltration is the central process of acute rejection. We hypothesized that ultrasound molecular imaging with T lymphocyte-targeted nanobubbles could be used to detect acute rejection in heart transplantation. In this study, nanobubbles bearing anti-CD3 antibody (NB CD3 ) or isotype antibody (NB con ) were prepared and characterized...
