RESUMEN
OBJECTIVES: The aim of this study was to analyze our 10-year experience with the HVAD in a real-world scenario in a high-volume German heart center. METHODS: We retrospectively analyzed outcomes of adults (≥18 years) with terminal heart failure (HF), who underwent HVAD implantation for durable LVAD therapy in our center between October 2009 and March 2020. Primary and secondary end points were all-cause death after implantation and LVAD-associated complications, respectively. We focused the distinct analyses on risk profiles at the time of implantation and implant strategies, i.e., bridge-to-transplant (BTT) or destination therapy (DT). RESULTS: A total of 510 patients were included, with 229 and 281 individuals in Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) level 1 (45%) and 2 to 4, respectively. Median follow-up was 26 months (IQR: 5-54 months). Overall survival at 1, 3, and 5 years after HVAD implantation was 66% (95% CI; 61.7-70%), 49.4% (95% CI; 44.9-53.8%), and 37.4% (95% CI; 32.8-42%), not censored for LVAD exchange, LVAD explantation, or heart transplantation. INTERMACS level 1 and peri-operative temporary right heart assistance were independent risk factors for survival. Survival was best in BTT patients undergoing heart transplantation at any time during follow-up. The INTERMACS level at time of HVAD implantation did not affect survival after heart transplantation. Freedom from the combined end point of any device-associated severe complication and death was 44.5% (95% CI; 40-48.8%) at 1-year after implantation. CONCLUSION: The HVAD is a reliable pump for durable mechanical circulatory support even in high-risk patients. Still, heart transplantation outperforms durable MCS therapy for a superior long-term survival.

Many patients with congenital cardiac disease need a regular cardiologic follow-up (FU) even after successful primary treatment. Nevertheless, many of them are lost to FU. The present study verifies for the first time the outcome of adults with congenital cardiac disease lost to FU of a specialized institution for >5 years.
