[Role of intraoperative transesophageal echocardiography in repair of mitral valve (our experience)].
BACKGROUND
Intraoperative transesophageal echocardiography (TEE) is a useful tool during valvular, great vessels and CABG surgery. In several large studies TEE has been shown to have higer sensitivity than TTE for native valve (94-100% vs. 44-63%) and prosthetic valves (75% vs 25%) both have high specificity (91-98%). TEE has got its value, particularly when surgeon intends to repair diseased valves, which are favorable operations due to its better survival rate, better ventricular function and fewer tromboembolic events. Most commonly valve repairs performed in patients with mitral and tricuspid valve diseases although reparative procedures have been described for all valve positions.


OBJECTIVE
Our aim is to define how important is TEE during mitral valve repairing operations.


METHODS
At our institution, during five years period (between may 1999. and may 2004.) 29 patients have been operated with mitral valve repairing and monitored by TEE intraoperatively. They all went through preoperative preparations at the Clinic for Heart diseases and rheumatism, as well as Cardiology dept. of Cardiac surgery clinic KCU Sarajevo. We were following ASE/SCE guidelines for intraoperative examination during four different intraoperative mitral valve surgery stages, using Siemens ultrasound machine Sonoline Versa Plus with TEE multiplane probe type MPT-4.


RESULTS
For 20 pts. (71%) mitral valve repairing has been performed solely, in 9 (29%) pts. combined mitral and tricuspide valves repairing. In two cases (6,9%) after not satisfied repairing cardiac surgeon had to replaced native (previously repaired) mitral valve with mechanical prosthesis. 7 pts. (24%) got Carpantier rings and others 22 (76%) have been operated with pericardium patch.


CONCLUSIONS
IOP TEE proved to be very useful in determination of the nature, severity and egzact anatomic location (scaloping) of the mitral and other valves disorders, in assessment of the urgency and feasibility of valves reparation and in plaining of the surgical procedures. In the case of poor surgical valve reparations, intraoperative TEE is the first method of choice in monitoring the process of valve reparation and in estimating the time for valve replacement.
