mitral valve repair
Surgical reconstruction of the mitral valve to restore normal function while preserving the native valve structure.
anastomosis
A surgical connection between two blood vessels, grafts, or hollow organs.
annuloplasty
Surgical repair of a heart valve annulus to restore normal valve function.
aortic annulus
Fibrous ring at the base of the aorta where the aortic valve leaflets attach; critical for valve sizing and function.
aortic dissection
Tear in the aortic wall creating a false lumen between arterial layers. Requires emergency surgical intervention in Type...
aortic insufficiency
Backward flow of blood from the aorta into the left ventricle due to incompetent aortic valve closure.
aortic regurgitation
Backward flow through the aortic valve during diastole causing left ventricular volume overload.
aortic root aneurysm
Pathological dilatation of the aortic root involving the sinuses of Valsalva and often requiring complex surgical repair...
aortic root replacement
Surgical replacement of the aortic root including the aortic valve and ascending aorta.
aortic stenosis
Narrowing of the aortic valve opening that restricts blood flow from the left ventricle to the aorta.
aortic valve replacement
Surgical procedure to replace a diseased aortic valve with a mechanical or biological prosthesis.
Aortic Valve Sparing Root Replacement
Surgical technique that preserves the native aortic valve while replacing the aortic root and sinuses of Valsalva.
aortocaval fistula
Abnormal communication between the aorta and inferior vena cava, often iatrogenic during cardiac surgery.
Aortopulmonary Window
Rare congenital heart defect characterized by an abnormal communication between the ascending aorta and pulmonary artery...
aortotomy
Surgical incision into the aorta to access the aortic valve or repair aortic pathology.
arterial graft
Artery used as conduit for coronary bypass, typically internal mammary or radial artery, offering superior long-term pat...
arterial switch operation
Surgical procedure to correct transposition of great arteries by switching the positions of the aorta and pulmonary arte...
autograft
Transplanted tissue taken from the same individual, commonly used for valve replacement in cardiac surgery.
Bentall procedure
Composite aortic root replacement including valve, root, and coronary artery reimplantation for complex aortic pathology...
bicuspid aortic valve
Congenital heart defect where the aortic valve has two leaflets instead of the normal three.
BIMA
Use of both internal mammary arteries as arterial conduits in coronary artery bypass surgery.
CABG
Coronary artery bypass grafting; surgical creation of alternative pathways around blocked coronary arteries.
cannulation
The placement of tubes (cannulas) into blood vessels or cardiac chambers to establish cardiopulmonary bypass or provide...
cardiac tamponade
Life-threatening condition where pericardial fluid compresses the heart and impairs filling.
cardioplegia
Solution used to arrest the heart and protect the myocardium during cardiac surgery.
