Official title
The Role of Cardiopulmonary Stress Testing in Diagnostic Evaluation of Paradoxical Low Gradient Aortic Valve Stenosis
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Severe aortic stenosis is a condition with poor life expectancy once it becomes symptomatic. There are no prospective studies illustrating the utility of cardiopulmonary stress (CPX) testing in diagnosing and prognosticating patients with paradoxically low gradient and low flow severe aortic stenosis. We aim to prospectively investigate the utility of CPX in this patient population with the hypothesis that utilizing CPX parameters would better identify higher risk patients warranting further evaluation and possibly intervention sooner.
