In cardiology, DVD refers to Degenerative Valve Disease, a condition characterized by the thickening of the heart valves.
Understanding Degenerative Valve Disease (DVD)
DVD affects the valves within the heart, which are essential for ensuring unidirectional blood flow. Specifically, the heart has valves between the atria and the ventricles to prevent backflow. One such valve, the mitral valve, is situated between the left atrium and the left ventricle. When DVD occurs, these valves thicken, potentially leading to impaired valve function.
-
Thickening of Valves: The primary characteristic of DVD is the thickening of the cardiac valves, which impacts their ability to open and close properly.
-
Mitral Valve: The mitral valve, located between the left atrium and left ventricle, is a common site for DVD.
Impact on Heart Function
DVD can have various effects on heart function, depending on the severity and which valve is affected:
-
Regurgitation: Thickened valves may not close completely, leading to blood leaking backward.
-
Stenosis: In some cases, thickened valves may not open fully, obstructing blood flow.
Diagnosis and Management
Diagnosis of DVD typically involves:
-
Echocardiography: An ultrasound of the heart to visualize valve structure and function.
-
Physical Examination: Listening to the heart for murmurs indicative of valve problems.
Management strategies depend on the severity of the condition and may include:
-
Medication: To manage symptoms such as heart failure.
-
Surgery: Valve repair or replacement may be necessary in severe cases.
