Unusual cardiac associations with Tetralogy of Fallot-a descriptive study.
We present a large single-center series (>2200 cases) operated for Tetralogy of Fallot (TOF). We analyzed the incidence of associated unusual and uncommonly described cardiac lesions and their diagnostic and therapeutic implications in TOF patients. This retrospective study was conducted by reviewing records of patients operated for TOF at a large tertiary care pediatric cardiac centre. From 2002 to 2008, a total of 2235 cases of TOF were evaluated with echocardiography, cardiac catheterization, and/or cardiac computed tomography followed by cardiac surgery. Known and well-described associations were excluded from the study. Unusual associations were tabulated. Several unusual associations having an incidence >0.1% were detected. These included subaortic membrane (1%), pulmonary venous abnormalities (0.5%), small left ventricle (0.5%), interrupted inferior vena cava (0.5%), mitral valve abnormalities (0.4%), hemitruncus (0.4%), tricuspid valve abnormalities (0.4%), biventricular dysfunction (0.3%), retroaortic innominate vein (0.3%), bicuspid aortic valve (0.2%), and pericardial effusion (0.2%). This series describes unusual, not previously routinely reported cardiac lesions associated with TOF that may affect management and should be sought on preoperative evaluation. We demonstrate that more unusual associations do exist in not infrequent numbers, i.e., a TET is not just a TET.
