Aortic regurgitation may be acute (occurring primarily after bacterial endocarditis or aortic dissection) or chronic (due to congenital bicuspid valve or rheumatic fever) and may be caused by valvular disease or an abnormality of the aorta. In most cases, acute AR leads to rapid deterioration of LV function with subsequent pulmonary edema and cardiac decompensation. Frequently, chronic AR may remain compensated for a long period of time, becoming symptomatic only when left heart failure develops. Auscultation reveals an S3 and a high-pitched, decrescendo early diastolic murmur. Another characteristic diagnostic finding is widened pulse pressure. Echocardiography is the most important diagnostic tool, both for confirming the diagnosis and determining the severity of disease. In asymptomatic patients, conservative treatment consists of symptom management and physical activity as tolerated. However, symptomatic patients or those with severely reduced LV function should undergo surgical aortic valve replacement #aorticregurgitation #pathologyusmle #aorticregurgitationpathology #cardiologyvideos #usmlelectures #usmlevideos usmlestep1videos #usmlestep1lectures
