Insights
Continuous flow left ventricular assist device (cf-LVAD) implantation shows promising survival for advanced heart failure patients. This study details early outcomes, highlighting survival rates and common complications like bleeding.
Area of Science:
- Cardiology
- Medical Devices
- Surgical Innovation
Background:
- Continuous flow left ventricular assist devices (cf-LVAD) improve survival in end-stage heart failure (HF).
- This study presents clinical experience with the initial 50 cf-LVAD patients at a single center.
Purpose of the Study:
- To describe the clinical experience and outcomes of the first 50 patients receiving cf-LVAD implantation.
- To compare pre-implant characteristics and clinical outcomes between bridge to transplantation/candidacy (BTT/BTC) and destination therapy (DT) groups.
Main Methods:
- Retrospective analysis of 50 patients who underwent cf-LVAD implantation between 2012 and 2019.
- Categorization into BTT/BTC (n=28) and DT (n=20) groups.
- Comparison of pre-implant data and post-operative outcomes.
Main Results:
- No in-hospital mortality observed.
- 22% all-cause mortality during an average follow-up of 14 months.
- First-year survival: 86% (BTT/BTC) and 90% (DT).
- Major bleeding (44%) and rehospitalization (76%) were common complications, with gastrointestinal bleeding being frequent.
Conclusions:
- This study provides initial short-term clinical outcomes for cf-LVAD patients in Korea.
- Improved outcomes are anticipated with newer cf-LVAD technology and dedicated multidisciplinary teams for end-stage HF management.
Background/Aims:
The continuous flow left ventricular assist device (cf-LVAD) has improved the survival of chronic end-stage heart failure (HF) patients. Here we describe our clinical experience of the initial 50 LVAD patients from a single center.
Methods:
A total of 50 patients underwent LVAD implantation as bridge to transplantation (BTT; n = 28, 56%), bridge to candidacy (BTC; n = 2, 4%), or as destination therapy (DT; n = 20, 40%) from 2012 to 2019. Pre-implant characteristics and clinical outcomes were compared between BTT/BTC and DT.
Results:
The median age of patients was 67 years (range, 59 to 73). Men were more likely to receive LVAD (76% vs. 24%) than women. DT patients were older, had smaller body surface area, and worse laboratory profiles than BTT/BTC patients. There was no in-hospital mortality. During an average of 14 months (range, 8 to 23), the all-cause mortality was 22%. The first-year survival was 86 and 90% in BTT/BTC and DT groups, respectively. Hemorrhagic stroke was the most common cause (27%) of death. In the BTT/BTC group, 22 patients successfully underwent heart transplantation during median duration of 10 months (range, 7 to 14). The most common post-LVAD complication during the first year of LVAD implantation was major bleeding (44%). A significant proportion (76%) of patients experienced rehospitalization with gastrointestinal bleeding as the most common cause.
Conclusion:
We describe short-term clinical outcome of LVAD patients from a single center for the first time in Korea. With the newer generation LVAD and a dedicated team approach, improved clinical outcomes of LVAD for end-stage HF are expected.
