Abstract

Patients with borderline small left heart (LH) structures who initially undergo single ventricle palliation (SVP) may eventually become candidates for biventricular conversion (BC). The purpose of this study was to describe our surgical experience with BC in patients with small LH. We reviewed our institution's records for patients who underwent BC after an initial SVP between 1995 and 2012. Patients underwent an aortopulmonary amalgamation procedure as a part of their initial palliation. Data on imaging, BC operative details, and re-interventions after BC were collected. Twenty-eight patients underwent BC. Twenty patients had hypoplastic left heart syndrome (HLHS), 7 patients had unbalanced common atrioventricular canal (uCAVC), and 1 had interrupted aortic arch with VSD. Stage of palliation at BC was stage 1 in 6 patients (21.4%), bidirectional Glenn in 19 (67.9%), and Fontan in 3 (10.7%). Prior to BC, the median left ventricular end-diastolic volume (LVEDV) by echocardiography was 58.1 mL/m(2) in the HLHS group and 28.1 mL/m(2) in the uCAVC group. After BC, the LVEDV increased to 91.3 mL/m(2) in the HLHS group and 58.5 mL/m(2) in the uCAVC group (p < 0.05 compared with pre-BC in both groups). Right ventricular pressure was l...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
