In this episode, we review the types, presentation, physical exam, and management of aortic regurgitation (AR). What is the difference between types Ia, Ib, Ic, Id, II, and III aortic regurgitation? Why is the murmur of acute AR barely audible compared to the murmur of chronic AR? What are Corrigan's pulse, Muller's sign, Quincke's sign, and De Musset's sign? What is the Austin Flint murmur? Why should vasoconstrictors such as phenylephrine, beta blockers and intra-aortic balloon pumps be avoided in acute AR? , focusing on acute and chronic AR. Why does the LV end-diastolic diameter (LVEDD) and LV end-systolic diameter (LVESD) matter in asymptomatic severe AR? What are the LVEDD, LVESD, and LV ejection fraction thresholds that prompt referral for aortic valve replacement in patients with chronic AR who are asymptomatic? Tune in for answers to these questions.
