Early Aortic vaLve surgEry Versus wAtchful waitiNg Strategy in Severe Asymptomatic aOrtic reguRgitation

This study compares two strategies for treating severe asymptomatic aortic regurgitation — a "leaky" heart valve where blood flows backwards into the heart — in people who feel no symptoms yet. It compares early surgery to a watchful waiting approach with regular monitoring. You may be eligible if: - You are 18 or older - You have moderate-to-severe or severe aortic regurgitation (grade 3 or 4) with no symptoms - Your heart pumping function (LVEF) is above 50% - You have no current indication for surgery - You have at most mild-to-moderate disease in other heart valves You may NOT be eligible if: - You are under 18 - Your kidney function is severely reduced (creatinine clearance below 30 mL/min) - You have a contraindication to MRI (pacemaker, certain metal implants, cerebral aneurysm clip) - You are pregnant - You have permanent atrial fibrillation Talk to your doctor to see if this trial is right for you.
