The Short-Term Results of Our Percutaneous Mitral Balloon Valvuloplasty Cases

Abstract

The aim of our study is to evaluate the short term results of percutaneous mitral balloon valvuloplasyi (PMBV) cases of our clinic. Percutaneous mitral balloon valvuloplasty was performed 62 patients (52 female, 10 male, mean age: 32.6±9.6) whose echocardiography showed mitral stenosis and no severe valve calcification. The differences observed between the haemodynamic parameters before and after the valvuloplasty are; the mitral valve area increasedfrom J.J±{).2 cm2 to 2.1±{).J cm2, mean mitral gradient decreasedfrom 19.2±15.4 mmHg to 3.2±4.4 mmHg, mean left atrium pressure decreased from 25.3±15.5 mmHg to J0.3-±f5.5 mmHg and the mean pulmonary arterial pressure decreased from 35.0±12.4 mmHg to 23.0±8.2 mmHg. The changes in all parameters were statistically significant. Complications occured are asfollows; mild mitral regurgitation (1-2°/4) in 5 patients (8%), cerebral embolus in 1 patient (1.6%), left atrial rupture with cardiac tamponade in 2 patients (3.2%). One of these 2 cases was operated under urgent conditions and commisurotomy and drenage was pe,formed. The next case was treated by pericardiosynthesis. in one case valvuloplasty was not succesfull. The mean increase·in patients mitral valve area was 1 cm2• Mean mitral gradient, left atrium and pulmonary arterial pressure were signi.ficantly decreased. As result, PMBV is an effective treatment technique which is reliable, easy to pe,form with low complication rate in carefully selected mitral stenosis patients.
