Abstract

Left ventricular assist device (LVAD) implantation in patients with advanced heart failure due to hypertrophic or restrictive cardiomyopathy (HCM/RCM) presents technical and physiologic challenges. We conducted a systematic review of observational studies to evaluate the utilization and clinical outcomes associated with LVAD implantation in patients with HCM/RCM and compared these to patients with dilated or ischemic cardiomyopathy (DCM/ICM). We searched MEDLINE, EMBASE, and Scopus from inception through May 2019 and included appropriate studies describing the use of an LVAD in patients with HCM/RCM. We identified six studies with a total of 2,766 patients with HCM/RCM and advanced heart failure, among whom 338 patients (12.2%) underwent LVAD implantation. In patients listed for transplant, the rate of LVAD implantation was significantly lower in patients with HCM/RCM compared to that in patients with DCM/ICM (4.4% vs. 18.2%, p < 0.001). Adverse clinical outcomes were significantly higher in HCM/RCM than in DCM/ICM, including operative/short-term mortality (14.0% vs. 9.0%), right ventricular failure (50.0% vs. 21.0%), infection (15.5% vs. 11.2%), bleeding (40.2% vs. 12.5%), renal failure (15.0% vs. 5.1%), stroke (5.0% vs. 2.4%), and arrhythmias (18.0% vs. 7.7%) (all p values <0.001).
