Abstract:
Objective To evaluate the immediate effect of percutaneous ventricular restoration (PVR) using the PARACHUTE system in ischemic cardiomyopathy patients with apical aneurysm.Methods The study included 25 patients who received PARACHUTE partitioning device (PVD) implantation in the Xiamen Cardiovascular Hospital between January 2015 to December 2016.Invasive left ventricular hemodynamic assessments as well as cardiac output and cardiac output index were analyzed.Results Twenty-five patients [mean age (65.4±11.9) years] suffered from left ventricular aneurysm and heart failure patients after anterior myocardial infarction were enrolled.Ventricular partitioning device implantation was successful in 24/25 (96.0%) patients.PVR was failed in 1 patient due to unable to land the PVD in a satisfactory location.After implantation, a significant increase in cardiac output [(3.83±0.72) L/min vs.(4.85±0.93) L/min, P<0.01] and cardiac index [(2.32±0.74) L/(min·m2) vs.(2.90±0.82) L/(min·m2), P<0.01] was found.Conclusions Our preliminary experience on percutaneous ventricular restoration using PARACHUTE system demonstrates its feasibility and safety with increase in cardiac output and cardiac index immediately following the device implantation.
