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

ANSWER 1: C. A regurgitant volume > equal to 60 mL per beat is highly suggestive of severe AR and not 50 mL per beat (Table 56-1).
