We developed a percutaneous left ventricular assist system (PLVAS) using a centrifugal pump. PLVAS is the transseptal left atrial-femoral artery bypass to unload the left ventricle using a centrifugal pump. This PLVAS can be implanted through the inguinal vessels under fluoroscopy and also in 2 cases additional transesophageal echocardiogram guiding was performed. This PLVAS was applied to 6 patients with profound heart failure and refractory cardiogenic shock. The implantation of PLVAS required 30-60 minutes. The PLVAS assist flow was maintained at 3.0-4.0l/min. One patient with acute myocardial infarction survived and has been doing well for more than 1 year. The complications directly related to this procedure were minimal. PLVAS appears to be useful for patients with severe heart failure and may be useful as a short-time support or bridge to other more aggressive forms of life support.
