Left Ventricular Outflow Tract Obstruction Unmasked by Nifedipine: A Therapeutic Pitfall in the Management of Chronic Aortic Regurgitation
Gian M. Novaro MD, L. Leonardo Rodriguez MD

This case report illustrates the aggravation of a clinically silent left ventricular outflow tract obstruction by the maintenance use of nifedipine in a patient with chronic severe aortic regurgitation, demonstrating a potential limitation of vasodilator therapy in the management of this patient population. Recognition of this clinical scenario and the importance of echocardiography in its detection is discussed.
