Dyspnea, Orthopnea, and Pedal Edema
A 67-year-old man with a history of hypertension presents with 3 months of increasing dyspnea, orthopnea, and lower extremity edema. His transthoracic echocardiogram is shown in Figures 56-1, 56-2 and 56-3.
QUESTION 1. All of the following would support a diagnosis of severe aortic regurgitation (AR) except:
A. Jet width > 65% left ventricular outflow tract (LVOT)
B. Regurgitant fraction > 50%
C. Regurgitant volume > 50 mL per beat
D. Holodiastolic flow reversal
E. None of the options
View Answer
