Intraoperative Doppler color flow mapping for decision-making in valve repair for mitral regurgitation. Technique and results in 100 patients.

摘要: Mitral valve repair provides substantial advantages over mitral replacement in patients with severe regurgitation. However, because of the possibility persistent regurgitation, an intraoperative technique is needed to provide immediate and accurate assessment adequacy before closure chest. One hundred pure regurgitation were studied epicardial Doppler color flow mapping immediately after repair. Intraoperative severity showed good agreement preoperative left ventriculography standard precordial echocardiography surgery. Postrepair studies satisfactory surgical results 92 patients. remaining eight demonstrated unsatisfactory results: significant four, systolic anterior motion dynamic ventricular outflow tract obstruction three, a flail leaflet one. In six patients, further surgery was performed during same thoracotomy. two postrepair findings confirmed on within 5 days, reoperation required. provided "safety net" that ensured successful outcome all 100 by providing surgeon direct means assess success operation need for
