Aortic Regurgitation (Insufficiency) Explained Clearly

IRA PARNESS, MD

Thanks and I am a new subscriber trying out what's available. Obviously, this is not targeted to specialists. But as a cardiologist, I found the material incorrect in some regards and/or incomplete in others. Etiology- Rheumatic aortic regurgitation is an uncommon cause nowadays, although obviously a possible etiology. Nowadays, the most likely cause in younger people is congenitally bicuspid aortic valve with or without aortic dilation (seen in some degree in ~ 50% of patients). BiAV is also the commonest congenital defect in man, estimated to affect at least 1% of the population, most in an asymptomatic fashion but can be associated with AR or AS, the latter due to pre-senile calcification in middle age. Approximately 25% of patients with BiAV diagnosed at a mean age of 35 y need Aortic valve replacement and/or Ascending aorta replacement in 20 year follow up. Dx: Echo; Cath while still used has been supplanted in many by cardiac MRI +/- CT angiography; if used, it is primarily to obtain hemodynamic info and coronary angiography prior to surgery. RX: Correct about negatives of beta blockers. Hydralazine and nitrates - not in common use anymore for this indication. The role of chronic vasodilator Rx of AR is of uncertain value, but if used, most use Ace-i or ARBs. Surgery needs to be recommended before overt LV decompensation in asymptomatic patients. There are official American College of Cardiology recommendations for valvar heart disease treatment available, if you wish to consult them. Overall, I think the site seems good for exposure to areas where one has little or no knowledge. I saw a Covid-19 update that brought me to this site. I would recommend having lectures critiqued by expert consultants in the respective fields for current accuracy prior to publication and listing the most recent update date for the student.
