A 33-year-old guy arrives at the office feeling tired and with a diminished capacity for exercise during the previous six months. The patient had a course of antibiotic treatment after receiving an infective endocarditis diagnosis last year in the context of intravenous drug usage. Since then, he has not taken narcotics. The patient doesn't take any drugs and doesn't have any other health issues. On auscultation, a heart murmur can be detected. The arterial pulse rises and falls quickly in both carotid arteries. A systolic-diastolic bruit is produced when the stethoscope partially compresses the femoral arteries. When this patient's heart is catheterized, which of the following sets of pressure results is most likely to be seen?

Eductional Objective: Aortic regurgitation generates a left ventricular end-diastolic volume rise and a compensatory increase in stroke volume. It also causes a fast drop in aortic pressure during diastole. Aortic diastolic pressure is decreased, aortic systolic pressure is raised, and left ventricular diastolic and systolic pressures are elevated as a result of these hemodynamic changes.
