Excessive respiratory variation in tricuspid regurgitation systolic velocities in patients with severe tricuspid regurgitation.
AIMS Respiratory changes in tricuspid regurgitation (TR) systolic velocities are occasionally demonstrated by Doppler echocardiography in patients with TR. We tested the hypothesis that excessive respiratory changes in TR velocities are diagnostic of severe TR. METHODS AND RESULTS The difference between the maximal (expiratory) and minimal (inspiratory) TR systolic velocities during spontaneo...
متن کاملPhysiologic determinants of exercise capacity in patients with different types of right-sided regurgitant lesions: Ebstein's malformation with tricuspid regurgitation and repaired tetralogy of Fallot with pulmonary regurgitation.
BACKGROUND Exercise capacity relates to right ventricular (RV) volume overload in congenital heart disease and may improve after surgery. We herewith investigate the relation between exercise capacity, cardiac index, and RV volume overload due to tricuspid regurgitation (TR) in Ebstein's malformation and pulmonary regurgitation (PR) after repair of tetralogy of Fallot (rToF). METHODS We measu...
