Historical Aspects of Mechanical Circulatory Support

J. Timothy Baldwin; John T. Watson

Abstract

The mechanical circulatory support (MCS) devices of today trace their roots to ex-vivo studies in the 1930s, the clinical application for the heart-lung machine in the 1950s, and the advent of the National Institutes of Health Artificial Heart Program in the 1960s. Since then, MCS devices have evolved from large positive-displacement pumps with limited durability and large control consoles to battery-powered continuous-flow rotary pumps with compact smart controllers that are small enough to be implanted in infants. The progress made in these devices has occurred as a result of federal and private funding leading to various technological breakthroughs by talented and dedicated interdisciplinary teams of engineers, scientists, and clinicians. While the current devices provide a therapy for advanced stage heart failure patients to routinely live five years or longer with an MCS device with a better quality of life, adverse events such as strokes and infections are still common. Further progress on the devices with specific goals to overcome these issues is needed to benefit more heart failure patients and realize the full potential of MCS devices

Establishing the Concept

In the 1930s, Carrel and Lindbergh¹ developed an in vitro artificial heart-like apparatus for keeping organs alive outside the body. They removed the hearts, kidneys, ovaries, adrenal glands, thyroid glands, and spleens of small animals to watch them develop and function over the course of several days.² Acute animal studies in Russia and the United States followed in the 1940s. However, the meaningful origin of the modern era of mechanical circulation support (MCS) can be traced to the development of the heart-lung machine by Gibbon (Table 1.1) and its first successful clinical use in 1953.^3,4 The device was developed for cardiopulmonary bypass so that surgical cardiac procedures that require hours of circulatory support could be performed. The success of the device and the need for prolonged circulatory support for patients who could not be weaned from the heart-lung machine or whose hearts could recover with longer durations of support provided the initial impetus for developing devices that could provide long-term circulatory support. The optimism in the 1950s and 1960s that circulation could be successfully supported for extended periods by an artificial heart spurred its development by pioneers such as Kolff, Akutsu, DeBakey, Liotta, and Kantrowitz.⁵ In 1963, DeBakey and Lederberg testified before the US Congress on the need for an artificial heart in very different domains: for patients otherwise healthy except for their failed heart and for isolated travelers on long space journeys.⁶ These hearings coincided with the debate about the implications of the Russian Sputnik Program and unbridled national enthusiasm for taking on large technologic challenges such as the program to put the first man on the moon, which had begun just a few years earlier.
