[Cardiac surgery by the safe and easy insertion method with the J-shaped left ventricular vent catheter].

We experienced the safe and easy insertion method with the J-shaped left ventricular vent catheter. The catheter tip (about 15 cm) was vended in the J shape with the inner stainless steel introducer. This J-shaped catheter was inserted into the left atrium through the right upper pulmonary vein. Then this catheter was held vertically and only the outer silicone catheter was pushed into the left ventricle. In this method the catheter tip is turned to the front in the left atrium and inserted easily into the left ventricle along the anterior wall of the left atrium through the anterior margin of the mitral valve orifice.
