Percutaneous ventricular assist device (PVAD) is a minimally invasive treatment which can replace the function of the failing heart. It provides circulatory support for patients with severe emergent cardiovascular diseases such as complex coronary artery disease, acute myocardial infarction complicated by cardiogenic shock, and acute decompensated chronic heart failure. PVAD has been developed since the rise of the Hemopump, to the prosperity of the Impella, and increasingly been used as a haemodynamic support to improve prognosis. This article will review the evolution and clinical application of PVAD.
