In medical terms, DVR stands for Double Valve Replacement.
Based on surgical definitions, Double Valve Replacement (DVR) is a specific type of cardiac surgery. It is a surgical procedure performed on the heart that involves replacing two cardiac valves simultaneously. As highlighted in medical descriptions, it is considered a complex procedure that requires a highly experienced surgical team and a great deal of expertise.
Why is Double Valve Replacement Necessary?
The human heart has four main valves: the aortic, mitral, pulmonary, and tricuspid valves. These valves act like one-way doors, ensuring blood flows through the heart in the correct direction. When two of these valves become damaged or diseased – perhaps due to conditions like stenosis (narrowing) or regurgitation (leaking) – they may not function properly, affecting the heart's ability to pump blood efficiently. In such cases, replacing the damaged valves becomes necessary to restore normal heart function.
Common DVR Valve Combinations
While DVR can involve any two of the four heart valves, some combinations are more frequently encountered than others:
- Mitral Valve and Aortic Valve: This is one of the most common combinations for DVR.
- Aortic Valve and Tricuspid Valve: Another possible pairing depending on the patient's specific condition.
- Mitral Valve and Tricuspid Valve: Can also be required in certain scenarios.
The need for a Double Valve Replacement is determined through thorough medical evaluation, including imaging tests like echocardiograms, to assess the severity of valve damage.
This procedure is a significant surgical intervention aimed at improving heart function and alleviating symptoms caused by severe double valve disease.
