A 70-year-old man presents with progressive fatigue and newonset syncope. On exam, he has a 3/6 mid-peaking systolic murmur at the base that radiates upward but also apically. The second heart sound is paradoxically split, and the murmur does not change with handgrip. The ECG is notable for LV hypertrophy. Cardiac catheterization is performed and two intravascular pressure transducers are placed, one in the LV and one in the ascending aorta. Which of the following hemodynamic tracings is most consistent with the patient’s diagnosis?

A. Tracing 1

B. Tracing 2

C. Tracing 3

D. Tracing 4

E. Tracing 5
