Severe valve stenosis or regurgitation is a well-established indication for valve surgery due to the significant impact these conditions can have on cardiac function and overall health. When a valve becomes severely narrowed (stenosis) or leaky (regurgitation), it can lead to increased cardiac workload, heart failure symptoms, and serious complications if left untreated.

In the case of severe stenosis, the heart has to pump harder to move blood through the narrowed opening, which can lead to hypertrophy and eventually heart failure. Severe regurgitation can cause volume overload in the heart since blood flows backward into the heart chamber instead of progressing forward. Both scenarios can result in symptoms such as shortness of breath, fatigue, and chest pain, which may necessitate surgical intervention to repair or replace the affected valve to restore normal hemodynamics and improve the patient’s quality of life.

In contrast, mild valve regurgitation typically does not present with significant symptoms and is often monitored rather than surgically treated. Regular exercise habits and infrequent chest pain are not direct indicators for valve surgery; they do not reflect the severity of valve pathology that would warrant surgical intervention.
