How To Do It

Abstract

We describe our experience of a novel ‘two-window’ technique designed to assist in totally 3D-endoscopic mitral valve repair. A 10-mm trocar for a 3D-endoscope was inserted through the 4th intercostal space in the mid-axillary line. A main small incision (3 cm, 4th intercostal space) without rib spreading, and a second 1 cm incision (1–2 intercostal spaces above,) were made in the anterior axillary line. Soft tissue retractors were applied on both ports. A left atrial retractor, a left ventricular vent, and right-hand instruments were inserted through the main working port. A flexible aortic cross-clamp, an antegrade cardioplegia line, and left-hand instruments were inserted through the second port. Our two-window technique is safe, effective, and reproducible for totally endoscopic mitral valve repair.
