The valvular heart disease surgery
The valvular heart disease surgery Valvular heart disease (VHD) encompasses a range of conditions where one or more of the heart’s valves malfunction, impairing normal blood flow and potentially leading to serious health issues. The heart’s valves—namely the mitral, aortic, tricuspid, and pulmonary valves—serve to regulate unidirectional blood flow. When these valves become stenotic (narrowed) or regurgitant (leaking), the heart must work harder to maintain adequate circulation, often resulting in symptoms such as fatigue, shortness of breath, chest pain, and in severe cases, heart failure.
Surgical intervention is often necessary when medical management fails to alleviate symptoms or prevent disease progression. Valvular heart disease surgery aims to repair or replace the damaged valve to restore proper cardiac function. The decision on whether to repair or replace a valve depends on the type and severity of the lesion, the patient’s overall health, and the likelihood of surgical success.

The valvular heart disease surgery Valve repair is generally preferred when feasible because it preserves the native valve, maintains natural tissue, and often results in better long-term outcomes. Techniques may include annuloplasty (reinforcing the valve annulus), leaflet repair, or chordae tendineae reconstruction. Repair procedures are particularly common for mitral and tricuspid valves and are associated with a lower risk of complications like blood clots or infection.

There are two main types of prosthetic valves: mechanical and biological. Mechanical valves are durable but require lifelong anticoagulation therapy to prevent blood clots. Biological valves, made from bovine or porcine tissue, tend to have a limited lifespan but usually do not require long-term anticoagulation, making them suitable for older patients or those with contraindications to blood thinners.
The surgical approach varies based on the specific valve involved and the patient’s condition. Traditionally, open-heart surgery via median sternotomy has been the standard approach, allowing direct access to the heart. Advances in minimally invasive techniques and transcatheter procedures have transformed valvular surgery, especially for high-risk patients. Transcatheter Aortic Valve Replacement (TAVR), for instance, provides a less invasive means of addressing severe aortic stenosis in patients unable to undergo open surgery.

The valvular heart disease surgery Preoperative assessment involves a comprehensive evaluation including echocardiography, cardiac catheterization, and assessment of the patient’s overall health to determine surgical risk. Postoperative care focuses on managing pain, preventing infection, and monitoring for complications such as bleeding, arrhythmias, or prosthetic valve dysfunction. Long-term follow-up includes regular imaging to assess valve function and early detection of potential issues.
In conclusion, valvular heart disease surgery has evolved considerably, offering effective solutions that significantly improve quality of life and survival rates. Whether through repair or replacement, timely surgical intervention can prevent irreversible heart damage and address symptoms effectively, emphasizing the importance of early diagnosis and appropriate management.
