[Left ventricular pacemaker-lead implantation through left thoracotomy for cardiac resynchronization therapy].

: We performed direct implantation of a left ventricular pacemaker-lead through left thoracotomy for cardiac resynchronization therapy (CRT). We exposed the left ventricular free wall using a pericardium lifting method without hemodynamic deterioration or arrhythmia. Intraoperative ultrasonic cardiography is useful for determining a suitable implantation site for CRT.
