Abstract Background: Noncompaction is a poorly understood form of cardiomyopathy that typically affects the left ventricle and may be associated with congenital heart disease. Right ventricular noncompaction (RVNC) may occur when the left ventricle is affected but is rarely seen in isolation. RVNC may have clinical significance affecting surgical and long-term outcomes. We describe the diagnosis and clinical course in three patients at our institution.
Methods: We performed a retrospective review of patients diagnosed with RVNC over a 12- month period at our institution and reviewed their imaging and clinical course.
Results: Three patients were identified. All had diagnosis… More >

Abstract Sudden cardiac death (SCD), particularly in the young athlete, is a rare though devastating event for families, institutions, and communities at large. It can also affect the nonathlete and occur at rest, although most commonly associated with exercise activities and/or sports participation. Common causes of SCD include cardiomyopathies, particularly hypertrophic cardiomyopathy in the United States, congenital coronary artery anomalies, channelopathies, among others. This report will explore an overview of the prevalence and causes of SCD in the young. More >

Abstract Background: Arrhythmogenic cardiomyopathy (ACM) is a heritable disease characterized by fibrofatty replacement of cardiomyocytes, has a prevalence of approximately 1 in 5000 individuals, and accounts for approximately 20% of sudden cardiac death in the young (≤35 years). ACM is most often inherited as an autosomal dominant trait with incomplete penetrance and variable expression. While mutations in several genes that encode key desmosomal proteins underlie about half of all ACM, the remainder is elusive genetically. Objective: Here, whole exome sequencing (WES) was performed with genomic triangulation in an effort to identify a novel explanation for a… More >

Abstract Diabetic cardiomyopathy, i.e. the ventricular dysfunction in the absence of hypertension or coronary arterial disease, is a common complication of diabetes mellitus that leads to a heightened risk of heart failure and death among diabetic patients. This contractile dysfunction could be associated to mitochondrial dysfunction, in which mitochondrial biogenesis could emerge as a compensatory mechanism triggered in response to hyperglycemia. It has been proposed that nitric oxide synthase activities with enhanced NO production are involved in this process. Alterations in the contractile response and lusitropic reserve were observed in streptozotocin diabetic rats after β-adrenergic stimuli. Additionally,… More >
