0118: Right ventricular dysfunction in severe tricuspid regurgitation

Asymmetry of right ventricular enlargement in response to tricuspid regurgitation.

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 a...

General anesthesia with remifentanil for cesarean section in a parturient with severe mitral and tricuspid regurgitation

Valvular heart lesions have deleterious effects on hemodynamics in parturients during pregnancy. Cesarean section with an opioid-based general anesthesia is used to alleviate the adverse effects. We described a case of a 28-year-old primigravida at 37 weeks’ gestation with a diagnosis of severe mitral regurgitation, tricuspid regurgitation, and pulmonary hypertension in active labor. Cesarean s...

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...
