A ‘non-invasively measured contractility descriptor’ which is commonly used for predicting clinical outcomes among patients with “Aortic Regurgitation (AR)”, the leaking aortic valve without performing any surgery has also been found to be a superior method for measuring and determining the survival after AR after the “Aortic Valve Replacement (AVR)”.
Findings of this 28 years long research conducted by Dr, Jeffrey S. Borer were presented at the 57th Annual Scientific Sessions of the ‘American College of Cardiology (ACC)’. Dr.Jeffrey S. Borer is Professor of Cardiovascular Medicine at the Howard Gilman Institute for Valvular Heart Diseases.
Dr. Jeffrey S. Borer summarized his research findings and said, “Preoperative Wall-Stress-Adjusted Ejection Fraction Change with Exercise Best Predicts Survival after Aortic Valve Replacement for Chronic Severe Aortic Regurgitation.”
Dr. Jeffrey S.Borer did develop specific measure of contractility in the year 1990. With the help of this development it was possible to predict successfully about the adverse cardiac outcomes of heart failure. It is one of the sub-normal ejection fractions at rest which is a commonly known risk predictor and causes sudden death. The risk prediction is more easy with this method among the AR patients who have not has valve surgery.”For several years, we have been using this measurement to identify the time at which valve surgery should be performed for AR”, says Dr. Borer.
