International Registry for Mechanically Assisted Circulatory Support (IMACS)

IMACS logo The International Society for Heart and Lung Transplantation Registry for Mechanically Assisted Circulatory Support (IMACS) is an international registry intended to enroll and follow patients who receive durable mechanically assisted circulatory support devices (MCSD) in all countries and hospitals that wish to participate. Durable devices are defined as those devices that are capable of allowing patient discharge with the device in place. Devices are defined on a country by country basis. The registry will record pre-implant patient information, device information and will track the major post implant clinical events.

ISHLT has awarded a three year contract to the Division of Cardiothoracic Surgery at the University of Alabama at Birmingham (UAB) under the direction of Dr. James K. Kirklin. UAB will serve as the data coordinating and analysis center (DCAC). The programming for the web-based data entry system will be performed by the Transplant Informatics Institute (TII), in Richmond, Virginia under a subcontract to UAB. TII is a subsidiary of the United Network for Organ Sharing (UNOS), which is the contractor for the United States Government’s Organ Procurement and Transplantation Network.
