Feb 16, 2017 · Although it’s been a decade since he retired from cardiothoracic surgery, Cleveland Clinic CEO and President Toby Cosgrove, MD, says he is “still haunted to this day by some of the deaths on my operating table 20 or 30 years ago.” He adds: “For a cardiac surgeon, death is traditionally seen as failure.

In the early days of mitral valve surgery, Dr. Cosgrove was confronted with the relative inflexibility of the retractor then being used for exposing the right and left atria. Noting the adaptability of the retractor he was using for internal thoracic artery dissection (the Favaloro retractor), he combined its best features with features from a mitr...
When preparing to perform aortic valve replacement in a patient whose ascending aorta (the usual site for cannulation) was calcified and whose femoral arteries (the preferred alternative) were also calcified, Dr. Cosgrove improvised by cannulating the axillary artery, under the arm. He went on to do similar cannulation on 26 other patients with ext...
A basic element of mitral valve repair is reinforcement of the annulus — the outer ring that holds the leaflets — to maintain the circumferential structure of the damaged valve. This is challenging because the mitral annulus is saddle-shaped and bends and rolls with each beat of the heart. It also expands toward the posterior. A stiff or unevenly s...
Large-handled clamps that shut the aorta during cardiac surgery can also block the surgeon’s view. Dr. Cosgrove saw an opportunity to develop a clamp whose handle could be activated from a distance, away from the surgeon’s tiny working space. Inspired by the concept behind bicycle hand brakes, he designed a flexible clamp whose handle could lay out...
During cardiac surgery, venous blood is drained through a cannula out of the heart and into the extracorporeal oxygenator, or heart-lung machine. Ordinarily, the cannula needs to be large because blood is moved through it by a gravity-driven siphon effect, which also requires the heart-lung machine to be close to the ground. While a large cannula i...
One of Dr. Cosgrove’s most recent innovations reduces the risk of stroke caused by blood clots originating in the sac-like heart structure called the left atrial appendage (LAA). Blood tends to pool and clot in the LAA. The clots escape through the mouth of the LAA and can travel to the brain, causing neurological damage. Working with A. Marc Gilli...
Some of Dr. Cosgrove’s ideas were ahead of their time and were later brought to maturity by others. Most of his ideas were realized only after long periods of analyzing a particular problem and the lengthy, sometimes discouraging process of trial and error. “I can attest,” he wrote, “that new enterprise receives little support and much criticism.” ...
Dec 11, 2017 · Fred DeGrandis, who retired from the Clinic a couple of years ago, said that when Cosgrove heard that his mother was recovering from a cardiac procedure, he asked to take a look at her chart.
Before retiring from surgery in 2006, Dr. Cosgrove achieved one of the most distinguished and accomplished careers in the field of cardiac and thoracic surgery. He performed more than 22,000 operations and earned an international reputation for expertise in all areas of cardiac surgery, especially valve repair.
Delos “Toby” Cosgrove, MD, was 28 when he took charge of his first hospital — a 100-bed facility on the perimeter of a military base in Vietnam, prone to rocket attacks.
