[Clinical experience of a percutaneous ventricular support for profound heart failure following acute myocardial infarction--a case report].
Percutaneous biventricular support with centrifugal pump was applied to a 59-year-old man with profound heart failure following acute myocardial infarction. Direct coronary angioplasty was performed under percutaneous cardiopulmonary support (PCPS). After angioplasty, he could not be weaned from PCPS under IABP. We used percutaneous left ventricular support (PLVS) with transseptal left atrial cannulation. PLVS could not maintain effective assist flow and he developed a cardiogenic shock again. PCPS was added to PLVS, and percutaneous biventricular support was started. Assist flow ranged 1.7-3.0 L/min in PLVS, and 1.7-2.0 L/min in PCPS, and total assist flow was 3.4 L/min. Pulsatile pressure was obtained by adding IABP. The patient was successfully weaned from PCPS in 26 hours and PLVS in 118 hours. Patient is alive and well one year after PLVS. Combination of PLVS and PCPS is an effective ventricular support system, being less invasive than conventional method with thoracotomy, and may be useful for profound heart failure.
