Second annual report from the ISHLT Mechanically Assisted Circulatory Support Registry

Area of Science:

• Cardiology
• Medical Devices
• Public Health

Background:

• The International Registry Report provides a comprehensive overview of mechanical circulatory support device usage.
• Continuous flow pumps represent the predominant technology in global practice.

Purpose of the Study:

• To present the second annual report of the International Mechanical Circulatory Support (IMACS) registry.
• To analyze survival rates, adverse events, and update the risk model for patients with mechanical circulatory support devices.
• To highlight key risk factors influencing outcomes in a large, international patient cohort.

Main Methods:

• Data compilation from over 14,000 patients across 35 countries.
• Analysis of survival data at one and two years post-implantation.
• Identification and evaluation of risk factors, including congenital heart disease and biventricular support.

Main Results:

• One-year survival remains at 80%, and two-year survival at 70%.
• Congenital heart disease and biventricular support identified as the most significant risk factors.
• Continuous flow pumps are the dominant device type utilized globally.

Conclusions:

• The IMACS registry database is a valuable resource for understanding outcomes in mechanical circulatory support.
• The findings underscore the importance of identifying and managing risk factors for improved patient survival.
• The database is well-positioned for future in-depth analyses of novel trends and interventions.
