Heart Valve Repair

Heart valve repair is a surgical procedure used to correct problems with one or more of the heart's four valves: the aortic, mitral, pulmonary, and tricuspid valves. These valves play a crucial role in ensuring that blood flows in the correct direction through the heart chambers. When one of these valves becomes damaged or diseased, it can result in impaired blood flow and lead to a variety of serious complications, including heart failure, stroke, and other cardiovascular problems. Heart valve disease can involve either stenosis (narrowing) or regurgitation (leakage), both of which can affect heart function. Mitral valve prolapse (MVP) and aortic stenosis are some of the most common valve problems that require intervention. When the condition is severe and other treatments, such as medications, fail to manage the symptoms, heart valve repair is considered a viable treatment option. Unlike valve replacement, which involves removing the damaged valve, heart valve repair aims to restore the function of the existing valve, which tends to offer better long-term outcomes for the patient. This blog provides an in-depth overview of the causes, symptoms, diagnosis, treatment options, and lifestyle management for those who may require heart valve repair.

Causes Heart valve disease can occur due to several underlying conditions, either congenital or acquired, that affect the heart valve's ability to function properly. Some common causes include:

Mitral Valve Prolapse (MVP): A condition where the mitral valve's leaflets bulge into the left atrium, causing it to leak. MVP is a common cause of mitral regurgitation, leading to heart valve dysfunction.

Rheumatic Fever: An autoimmune response to a throat infection (usually caused by streptococcus bacteria) that can damage the heart valves. This is a major cause of valve disease, particularly in developing countries.

Aortic Stenosis: The aortic valve becomes stiff or calcified, which prevents it from opening fully. Over time, this leads to increased pressure in the left ventricle and can affect the heart's ability to pump blood effectively.

Infective Endocarditis: This is an infection of the inner lining of the heart, which can damage the valves, leading to valvular insufficiency or regurgitation. People with pre-existing heart valve defects or prosthetic valves are at higher risk for this infection.

Degenerative Changes: As people age, the heart valves may become thickened, calcified, or weakened, resulting in stenosis or regurgitation. This is commonly seen with the aortic and mitral valves.

Congenital Heart Defects: Some people are born with structural issues in the heart valves that may require repair as they grow older. Congenital defects may affect any of the four valves.
