Heart Valve Replacement

Heart valve replacement addresses one of the more serious forms of heart disease — when a valve no longer opens or closes properly, forcing the heart to work harder and, over time, risking heart failure if left untreated. Modern valve replacement techniques have made this a far less invasive procedure than it once was for many patients.

Why valves fail

Heart valves can become damaged through several causes: age-related calcification and stiffening, congenital defects present from birth, infection (endocarditis), or as a consequence of rheumatic fever earlier in life. The result is either a valve that doesn't open fully (stenosis) or one that doesn't close completely, allowing blood to leak backward (regurgitation).

Two approaches to replacement

Traditional open-heart surgery

The valve is replaced through an incision in the chest, with the heart temporarily stopped and blood circulated by a heart-lung machine. This remains the standard approach for many patients, particularly when multiple valves or other cardiac issues need addressing at the same time.

Minimally invasive and catheter-based replacement

For certain patients, particularly those with aortic valve disease, a newer technique delivers the replacement valve via catheter — often through the femoral artery — without opening the chest. This generally means a shorter hospital stay and faster recovery, though it isn't suitable for everyone; your cardiologist will assess based on valve type, overall anatomy, and surgical risk.

Mechanical versus biological valves

Replacement valves come in two main types, each with real trade-offs:

1. Mechanical valves are extremely durable and rarely need replacing again, but require lifelong blood-thinning medication
2. Biological (tissue) valves don't require long-term blood thinners but typically wear out after 10–20 years, which matters more for younger patients who may eventually need a second procedure

This decision is made jointly with your cardiac team based on age, lifestyle, and other health factors.

Recovery timeline

Open-heart valve replacement typically involves a hospital stay of five to seven days, followed by six to eight weeks of restricted activity and a structured cardiac rehabilitation program. Catheter-based replacement often allows discharge within two to three days and a notably faster return to normal activity.

Talking through your options

Valve disease often progresses gradually, which means there's usually time to properly understand your options rather than rush a decision. Our cardiology specialists can review your echocardiogram results with you, explain which replacement approach fits your specific case, and provide a clear cost breakdown before you commit to a hospital or surgeon.
