[Value of Doppler echocardiography in the indications for correction of tricuspid valve insufficiency in the course of mitral valve implantation].
To assess the postoperative reversibility of functional tricuspid regurgitation (FTR) and its relation to preoperative pulmonary artery systolic pressure (PASP) 103 patients were studied by Doppler echocardiography (DE) in whom at the time of mitral valve replacement the correction of the FTR was not considered to be necessary by the surgeon. Moderate or severe FTR was found in 36% of patients preoperatively, and it diminished or disappeared early after operation if the preoperative PASP was more than 60 mmHg, while the improvement of FTR was found only in the half of patients with PASP less than 60 mmHg. Persistent FTR was still unchanged in 7 of 10 patients at 1 year follow-up. It is concluded that DE should be performed prior to mitral valve replacement and severe FTR found by DE should be surgically treated even in case of negative surgical findings if the PASP is less than 60 mmHg.
