Valvular hemangioma incidence is extremely low. In this report, we describe a 62-year-old man who presented with mild edema of the lower limbs. An echocardiogram revealed an incidental 1.3-cm diameter mass on the anterior mitral valve leaflet for which he underwent surgical resection and mitral valve replacement. Histopathological examination showed a lymphocyte-rich capillary-cavernous hemangioma. The exuberant lymphoid stroma is unusual for hemangioma and represents an undescribed pattern of cardiac hemangioma...

BACKGROUND: Cardiotoxicity is a documented complication of Crotalinae envenomation. Reported cardiac complications following snake envenomation have included acute myocardial infarction, electrocardiogram abnormalities and arrhythmias. Few reports exist describing arrhythmia induced by viper envenomation and to our knowledge none describe arrhythmia induced by Crotalinae envenomation. This report concerns the first known case of atrial fibrillation precipitated by rattlesnake bite. CASE PRESENTATION: A 73-year-old Caucasian man with a past medical history of hypertension, hyperlipidemia, type 1 diabetes mellitus, and a baseline first-degree atrioventricular block presented to the emergency department following a rattlesnake bite to his left lower leg...

BACKGROUND: Repair of complete atrioventricular canal (CAVC) with tetralogy of Fallot (TOF) is a challenging operation increasingly being performed as a complete, primary repair in infancy. Previous studies have focused on perioperative outcomes; however, midterm valve function, ventricular function, and residual obstruction have received little attention. METHODS: We retrospectively reviewed 20 patients who underwent CAVC/TOF repair (January 2005 to December 2014)...

Barry Burstein, Dev Jayaraman, Regina Husa
Although echocardiograms are frequently performed within 24 h of sudden cardiac death, the utility of left ventricular ejection fraction (LVEF) to predict survival is unknown. In this is single center retrospective cohort study of patients admitted to the intensive care unit or coronary care unit after in-hospital or out-of-hospital sudden cardiac death, LVEF <40% was not a significant predictor of survival at 30 days or hospital discharge. ABSTRACT Background: Cardiopulmonary resuscitation and early defibrillation have been shown to improve outcomes of cardiac arrest...

We sought to determine the natural history of aortic valve disease in patients with unrepaired perimembranous ventricular septal defects (pVSDs) and to identify echocardiographic parameters predictive of increased risk of surgical repair of pVSD because of aortic valve disease. We retrospectively analyzed all echocardiograms of patients with a diagnosis of pVSD at our institution from January 1999 to January 2015. All available echocardiographic data were collected. Patients were excluded if there was another structural cardiac anomaly other than bicuspid aortic valve, small patent foramen ovale, or ductus arteriosus...

BACKGROUND: Translational failure for cardiovascular disease is a substantial problem involving both high research costs and an ongoing lack of novel treatment modalities. Despite the progress already made, cell therapy for chronic heart failure in the clinical setting is still hampered by poor translation. We used a murine model of chronic ischemia/reperfusion injury to examine the effect of minimally invasive application of cardiac progenitor cells (CPC) in cardiac remodeling and to improve clinical translation...

Objectives. Ulcerative colitis (UC) and Crohn's disease (CD) are chronic inflammatory bowel diseases (IBD) with unclear underlying aetiologies. Severe cardiac arrhythmias have been emphasised in a few studies on adult IBD patients. This study aimed to investigate the alteration of the P-wave and QT interval dispersion parameters to assess the risk of atrial conduction and ventricular repolarisation abnormalities in pediatric IBD patients. Patients and Methods. Thirty-six IBD patients in remission (UC: 20, CD: 16) aged 3-18 years and 36 age- and sex-matched control patients were enrolled in the study...

Aspergillus pericarditis is a rare and life-threatening infection in immunosuppressed patients. It has nonspecific clinical manifestations that often mimic other disease entities especially in patients who have extensive comorbidities. Diagnosis is oftentimes delayed and rarely done antemortem. A high degree of suspicion in immunocompromised patients is necessary for evaluation and timely diagnosis. This is a case of Aspergillus pericarditis with cardiac tamponade in a renal transplant patient with liver cirrhosis...

BACKGROUND: Human epidermal growth receptor 2 (HER2) targeted therapies have survival benefit in adjuvant and metastatic HER2 positive breast cancer but are associated with cardiac dysfunction. Current U.S. Food and Drug Administration recommendations limit the use of HER2 targeted agents to patients with normal left ventricular (LV) systolic function. METHODS: The objective of the SAFE-HEaRt study is to evaluate the cardiac safety of HER2 targeted therapy in patients with HER2 positive breast cancer and mildly reduced left ventricular ejection fraction (LVEF) with optimized cardiac therapy...

A 6-d-old Indian-origin female rhesus macaque (Macaca mulatta) presented with bradycardia shortly after sedation with ketamine. No other cardiac abnormalities were apparent. Approximately 2 wk after the initial presentation, the macaque was again bradycardic and exhibited a regularly irregular arrhythmia on a prestudy examination. ECG, echocardiography, blood pressure measurement, SpO2 assessment, and a CBC analysis were performed. The echocardiogram and bloodwork were normal, but the infant was hypotensive at the time of echocardiogram...

Cardiac calcified amorphous tumour (CAT) is a rare non-neoplastic lesion with only a few cases reported in literature. We present an interesting case of CAT that was associated with unexpectedly low platelet count. A 40-year man presented with shortness of breath on exertion. Echocardiogram showed a mobile mass within the right atrium. Mass was surgically excised. His platelet count varied from 26,000/ul to 54,000/ul before surgery, which increased postoperatively. Histopathological examination revealed amorphous mass of eosinophilic fibrin with dense calcification...

PURPOSE OF REVIEW: Antibody-mediated rejection (AMR) currently represents one of the main problems for clinical management of heart transplant because of its diagnostic complexity and poor evidences supporting treatments. RECENT FINDINGS: Disorder-based diagnosis is a cornerstone in defining AMR. The limitations of the current classification have been partially overcome by novel studies improving the description of the immune-pathological graft abnormalities, and by new molecular approaches allowing a better understanding of the mechanisms behind AMR and of its relationship with cellular rejection and chronic vasculopathy...

Aortopulmonary window is a rare cardiac developmental anomaly characterised by a communication between the ascending aorta and the pulmonary artery. Aortopulmonary window may be isolated or associated with cardiac defects such as ventricular septal defect, atrial septal defect, interrupted aortic arch, and tetralogy of Fallot. We report a case of aortopulmonary window associated with aberrant subclavian artery based on fetal two-dimensional echocardiogram. The mother was referred for fetal echocardiography because of multiple fetal anomalies...
