Heart Valve Replacement

Heart valve replacement is a surgical procedure that replaces a damaged heart valve with a new one. The heart contains four valves – the aortic valve, mitral valve, pulmonary valve, and tricuspid valve – which ensure that blood flows in the correct direction through the heart and to the rest of the body. When one or more of these valves become damaged, they may no longer function properly, causing blood to flow backward, restrict normal blood flow, or lead to other complications.

The most common reasons for valve dysfunction are valvular heart disease (VHD), calcification, congenital valve defects, and conditions like endocarditis or rheumatic fever. If these conditions are severe, heart valve replacement may be necessary to prevent complications such as heart failure, stroke, or other severe symptoms.

Laparoscopic heart valve replacement is a minimally invasive technique that allows surgeons to replace damaged valves using small incisions, guided by a camera. This technique has revolutionized the way valve replacement surgery is performed, reducing recovery time, scarring, and complications, and offering an option for high-risk patients.

This procedure can replace damaged valves with either mechanical valves (made of durable materials) or biological valves (made from animal or human tissue). The decision to replace a valve with a mechanical or biological one depends on factors such as age, medical history, and lifestyle.

Heart valve disease occurs when one or more of the valves in the heart are no longer able to function properly. The reasons behind this valve dysfunction can vary widely, from degeneration over time to congenital defects.

Aortic stenosis is the narrowing of the aortic valve, often caused by calcification (calcium buildup) over time. This causes the valve to become stiff, which limits its ability to open properly, restricting blood flow from the heart to the rest of the body.

Mitral Regurgitation:

Mitral regurgitation occurs when the mitral valve does not close properly, allowing blood to leak backward into the left atrium. This can lead to heart failure and is often caused by mitral valve prolapse, where the valve bulges into the left atrium during contraction.
