BACKGROUND: Analysis of right ventricular adaptation to tricuspid regurgitation was studied in 10 heart transplant recipients following inadvertent endomyocardial biopsy disruption of the tricuspid apparatus. METHODS AND RESULTS: Echocardiography demonstrated progressive diastolic right ventricular cavity enlargement (19.5+/-5.0 to 30.3+/-5.4 cm(2), P<0.0002), with disproportionate elongation along the midminor axis (3.5+/-0.6 to 5. 0+/-0.5 cm, P<0.001). As the right ventricle remodeled to more spherical (and less elliptical) proportions, the end-diastolic right ventricular midminor axis/long axis ratio increased significantly from 0.52+/-0.10 to 0.68+/-0.07, P<0.005. CONCLUSIONS: Ventricular enlargement due to right ventricular volume overload results in disproportionate dilation along the free wall to septum minor axis.
