[The method of atriotomy, ventriculotomy and their repairs]

In this series, we describe the method of atriotomy, ventriculotomy and their repairs. Right atriotomy is needed for expose tricuspid valve, atrial and ventricular septal defect. Left atriotomy is needed for expose mitral valve disease and technique for, maze or pulmonary vein isolation. Left ventriculotomy is needed for resection of scar and/of thrombus of ventricular aneurysm, repair of ventricular septal rupture and endoaneurysmorrhphy. Recently, this method is also used to repair for ischemic mitral valve regurgitation. These techniques have already been described in many textbooks. Regarding atriotomy and ventriculotomy, the most important point is how to fully expose the tricuspid and mitral valves and others. The repair of ventriculotomy requires strips of teflon felt to strengthen the suture line and to enhance hemostasis. This method of repair is considered standard by many surgeons.
