FIGURE.

Tricuspid regurgitation severity (1+ to 4+) by preoperative (Preop) transthoracic echocardiography (TTE), by intraoperative transesophageal echocardiography (TEE) before and after cardiopulmonary bypass (CPB), and predischarge (pre-DC) TTE in 115 patients with more than mild tricuspid regurgitation undergoing mitral valve repair for mitral regurgitation. Severity under general anesthesia (both pre-CPB and post-CPB) was significantly less than both preoperative and pre-DC levels (P<.001 in all).
