Abstract
The incidence of hemopericardium following percutaneous mitral valvuloplasty is reported at 1-3%, being related to either trans-septal puncture, or left ventricular perforation with guide wires or balloons. We report a case of percutaneous mitral valvuloplasty for a middle-aged man with moderately severe rheumatic mitral stenosis. The procedure was performed through a right femoral vein approach, employing the multitrack technique, utilizing 2 balloons (20 and 18 mm). Inadvertently, the procedure was complicated by cardiac tamponade. Despite immediate diagnosis and prompt pericardiocentesis, hemodynamic stability was not maintained. Echocardiography revealed a mass in the posterior pericardial sac. The patient was arrested in asystole, and rigorously resuscitated during transfer to the operating room. Exploration revealed a tear in the left ventricular apex that was adequately sutured. In a few days, the patient gradually regained adequate consciousness, and was ultimately discharged. Post-procedural echocardiography revealed a mitral valve area of 1.9 cm(2), with no mitral regurgitation.
