REVIEW
Domenico Corrado, Cristina Basso, Daniel P Judge
Arrhythmogenic cardiomyopathy is an inherited heart muscle disorder, predisposing to sudden cardiac death, particularly in young patients and athletes. Pathological features include loss of myocytes and fibrofatty replacement of right ventricular myocardium; biventricular involvement is often observed. It is a cell-to-cell junction cardiomyopathy, typically caused by genetically determined abnormalities of cardiac desmosomes, which leads to detachment of myocytes and alteration of intracellular signal transduction...

A 50-year-old man with a murmur since birth developed systemic arterial hypertension as an adult. He came to the hospital because of dyspnea. He had a pulmonic valve ejection click and a murmur of pulmonic stenosis. His echocardiogram showed biventricular hypertrophy, a flat ventricular septum, a D-shaped left ventricle, systolic doming of the pulmonic valve, and Doppler evidence of a 70 mm Hg peak systolic pressure gradient across the pulmonic valve and a peak right ventricular systolic pressure of 100 mm Hg...

Graft dysfunction is the main cause of early mortality after heart transplantation. In cases of severe graft dysfunction, temporary mechanical circulatory support (TMCS) may be necessary. The aim of this systematic review was to examine the utilization and outcomes of TMCS in patients with graft dysfunction after heart transplantation. Electronic search was performed to identify all studies in the English literature assessing the use of TMCS for graft dysfunction. All identified articles were systematically assessed for inclusion and exclusion criteria...

CONTEXT: The nature of scorpion-related cardiomyopathy is still a matter of debate where specific toxin-induced cardiomyopathy, ischemic, or catecholaminergic cardiomyopathy is advocated as well. We report two cases of Takotsubo syndrome following envenomation by Androctonus australis, bringing new evidence for the fundamental role of catecholamines in the pathogenesis of this cardiomyopathy. Case 1: A woman aged 36 presented with pulmonary edema and shock following scorpion envenomation...

INTRODUCTION: Effects of cardiac resynchronization therapy (CRT) on arrhythmogenicity and sudden death have not been fully ascertained. CRT has been shown to increase transmural dispersion of repolarization (TDR) immediately on implantation, that may favorably remodel on long-term follow-up. However, such a hypothesis has not been prospectively evaluated. METHODS AND RESULTS: We included 35 consecutive patients who underwent CRT implantation between September 2013 & August 2014 (mean age 56...

Selecting an appropriate surgical approach for double-outlet right ventricle (DORV), a complex congenital cardiac malformation with many anatomic variations, is difficult. Therefore, we determined the feasibility of using an echocardiographic classification system, which describes the anatomic variations in more precise terms than the current system does, to determine whether it could help direct surgical plans. Our system includes 8 DORV subtypes, categorized according to 3 factors: the relative positions of the great arteries (normal or abnormal), the relationship between the great arteries and the ventricular septal defect (committed or noncommitted), and the presence or absence of right ventricular outflow tract obstruction (RVOTO)...

BACKGROUND Primary aldosteronism can be caused by adrenocortical adenoma and is usually associated with left ventricular hypertrophy. Biventricular cardiac hypertrophy and heart failure in the presence of a pre-existing atrial septal defect (ASD) are a rare association of primary aldosteronism. CASE REPORT A 33-year-old woman with resistant hypertension and refractory hypokalemia presented with signs and symptoms of heart failure. She had previously been diagnosed having a right adrenal tumor and ostium secundum type ASD...

Congenital complete heart block affects 1/15,000 live-born infants, predominantly due to atrioventricular nodal injury from maternal antibodies of mothers with systemic lupus erythermatosus or Sjogren's syndrome. The majority of these children will need a pacemaker implanted prior to becoming young adults. This article will review the various patient and technical factors that influence the type of pacemaker implanted, and the current literature on optimal pacing practices. Areas covered: A literature search was performed using PubMed, Embase and Web of Science...

BACKGROUND: Systemic-to-pulmonary shunts are useful palliative procedures, although many teams have been deterred by high mortality and morbidity. We aimed to identify predictors of adverse outcomes after shunts in biventricular lesions. METHODS: From 2004 to 2014, 173 children had shunt procedures. Morphologies included: tetralogy of Fallot, pulmonary atresia with ventricular septal defect (VSD) with and without major aortopulmonary collaterals (MAPCAs), transposition of great arteries with pulmonary stenosis, and double outlet right ventricle...

Late complications can arise after explantation of a left ventricular assist device. We report the case of a patient who presented at the age of 19 years with peri-partum cardiomyopathy and was initially managed with a biventricular support device, which was subsequently upgraded to an ambulatory left ventricular assist device. This was successfully explanted after myocardial recovery via a minimally invasive approach 7 months later. The patient re-presented 5 years following explantation with hemoptysis. At redo sternotomy, a 10-cm remnant of the outflow graft was found to be eroding the surface of the right lung...

Fetal cardiac intervention (FCI) is a relatively new and continually evolving field, and, for select cardiac defects, offers the potential to alter the progression of the disease and improve outcomes. It is a procedure that requires a collaborative effort between maternal-fetal medicine, interventional cardiology and fetal echo/ultrasound specialists, as well as fetal and maternal anesthesiologists, nursing specialists, and social workers. This article reviews the most recently reported data and advances in FCI...
