What is the main purpose of a Ventricular Assist Device?

• A. reduces workload/afterload of heart and increase coronary perfusion
• B. replaces the heart permanently
• C. cures coronary artery disease
• D. eliminates need for medications

Answer: (A)

Ventricular Assist Devices deliver mechanical circulatory support by unloading the failing ventricle and providing forward blood flow, which lowers the heart’s workload and afterload while maintaining systemic perfusion. By taking pressure and volume off the ventricle, end-diastolic pressure and wall stress fall, reducing myocardial oxygen demand. The device pumps blood into the aorta, boosting systemic flow and improving organ perfusion, which in turn helps the heart (and the rest of the body) function better while awaiting recovery or a transplant. This isn’t a permanent heart replacement; it’s support used as a bridge to transplant or as destination therapy in some cases. It doesn’t cure coronary artery disease, which is the underlying issue in many heart failures. Medications remain important for managing blood pressure, fluid status, and anticoagulation with an implanted device.
