Tirone Esperidiao David, OC OOnt FRCS (born November 20, 1944) is a Brazilian-born Canadian cardiac surgeon and professor of surgery at the University of Toronto. He is an attending cardiac surgeon at the Peter Munk Cardiac Centre, Toronto General Hospital. He is known for his 2007 development of a valve sparing aortic root replacement procedure to preserve the aortic valve in patients with aortic root aneurysms such as in Marfan syndrome; it is now known as the "David Operation". [1]
Born in Ribeirão Claro, Brazil, to a Syrian Jewish father and an Italian mother. [2] [3] he graduated from the Universidade Federal do Paraná as a medical doctor in 1968. He completed his surgical internship at SUNY Downstate Medical Center and his general surgery residency at Cleveland Clinic in Cleveland. In 1975, he came to Toronto to train in cardiovascular and thoracic surgery at the University of Toronto.
He joined the academic staff of Toronto General Hospital in July 1978. He was chief of cardiovascular surgery at Toronto Western Hospital from 1980 through 1989 and Toronto General Hospital from 1989 through 2011. In 2004, he was elected University Professor, the highest honour the University of Toronto bestows its professors. From 2004-2005, he served as president of the American Association for Thoracic Surgery. [4]
He has published extensively in peer reviewed journals, is the author of many chapters in surgical textbooks, and is the editor or co-editor of 5 surgical textbooks.
David has received numerous awards. In 1993 he was elected as a member of the Order of Ontario, and in 1996, he was made an Officer of the Order of Canada. [5]
He is also a member of the Canadian Marfan Association's Professional Advisory Board.
Marfan syndrome (MFS) is a multi-systemic genetic disorder that affects the connective tissue. Those with the condition tend to be tall and thin, with long arms, legs, fingers, and toes. They also typically have exceptionally flexible joints and abnormally curved spines. The most serious complications involve the heart and aorta, with an increased risk of mitral valve prolapse and aortic aneurysm. The lungs, eyes, bones, and the covering of the spinal cord are also commonly affected. The severity of the symptoms is variable.
Aortic dissection (AD) occurs when an injury to the innermost layer of the aorta allows blood to flow between the layers of the aortic wall, forcing the layers apart. In most cases, this is associated with a sudden onset of agonizing chest or back pain, often described as "tearing" in character. Vomiting, sweating, and lightheadedness may also occur. Damage to other organs may result from the decreased blood supply, such as stroke, lower extremity ischemia, or mesenteric ischemia. Aortic dissection can quickly lead to death from insufficient blood flow to the heart or complete rupture of the aorta.
Aneurysm of the aortic sinus, also known as the sinus of Valsalva, is a rare abnormality of the aorta, the largest artery in the body. The aorta normally has three small pouches that sit directly above the aortic valve, and an aneurysm of one of these sinuses is a thin-walled swelling. Aneurysms may affect the right (65–85%), non-coronary (10–30%), or rarely the left coronary sinus. These aneurysms may not cause any symptoms but if large can cause shortness of breath, palpitations or blackouts. Aortic sinus aneurysms can burst or rupture into adjacent cardiac chambers, which can lead to heart failure if untreated.
A thoracic aortic aneurysm is an aortic aneurysm that presents primarily in the thorax.
Aortic valve replacement is a cardiac surgery procedure whereby a failing aortic valve is replaced with an artificial heart valve. The aortic valve may need to be replaced because of aortic regurgitation, or if the valve is narrowed by stenosis.
The Toronto General Hospital (TGH) is a major teaching hospital in Toronto, Ontario, Canada and the flagship campus of University Health Network (UHN). It is located in the Discovery District of Downtown Toronto along University Avenue's Hospital Row; it is directly north of The Hospital for Sick Children, across Gerrard Street West, and east of Princess Margaret Cancer Centre and Mount Sinai Hospital. The hospital serves as a teaching hospital for the University of Toronto Faculty of Medicine. In 2019, the hospital was ranked first for research in Canada by Research Infosource for the ninth consecutive year.
Valve-sparing aortic root replacement is a cardiac surgery procedure which is used to treat Aortic aneurysms and to prevent Aortic dissection. It involves replacement of the aortic root without replacement of the aortic valve. Two similar procedures were developed, one by Sir Magdi Yacoub, and another by Tirone David.
The Bentall procedure is a type of cardiac surgery involving composite graft replacement of the aortic valve, aortic root, and ascending aorta, with re-implantation of the coronary arteries into the graft. This operation is used to treat combined disease of the aortic valve and ascending aorta, including lesions associated with Marfan syndrome. The Bentall procedure was first described in 1968 by Hugh Bentall and Antony De Bono. It is considered a standard for individuals who require aortic root replacement, and the vast majority of individuals who undergo the surgery receive mechanical valves.
Annuloaortic ectasia is characterized by pure aortic valve regurgitation and aneurysmal dilatation of the ascending aorta. Men are more likely than women to develop idiopathic annuloaortic ectasia, which usually manifests in the fourth or sixth decades of life. Additional factors that contribute to this condition include osteogenesis imperfecta, inflammatory aortic diseases, intrinsic valve disease, Loeys-Dietz syndrome, Marfan syndrome, and operated congenital heart disease.
