The Mechanical Heart: Clinical Reality or Science-Fiction?

Despite improvements in almost every facet of cardiovascular disease, the prevalence of congestive heart failure continues to rise. Traditionally, the only option for the management of end-stage heart disease was cardiac transplantation. In order to support potential candidates until a suitable donor organ can be found, various technologies have been introduced and the field of “mechanical circulatory support” has blossomed. The early versions of the “mechanical heart” were designed to support patients for days to weeks and necessitated large, morbid operations.

Advances in engineering, biocompatible interfaces and battery technology has resulted in the widespread use of a variety of approved devices both as a bridge to cardiac transplantation as well as “destination” or permanent therapy for non-transplant candidates. The number of Canadian medical centers providing long term mechanical circulatory support has significantly increased in the past 5 years. The introduction of “next generation” devices brings the promise of smaller surgery, better outcomes and longer durability. We anticipate that these devices will offer upwards of 5 years of good quality life in end-stage heart failure patients, many of whom face a median survival measured in months. In Canada, mechanical circulatory support has blossomed in the past 5 years. We anticipate that newer technology, increased experience and importantly, sustainable funding, will allow this therapy to be offered to all Canadians in need.
