Aortic valve

A 70-year-old Caucasian man is brought to the emergency room by his
wife after an episode of syncope while working in his garden. His wife says that he
has always been physically active, but complained of increased fatigability lately. His past medical history is significant for diabetes mellitus type-2 and gout. His only current medication is glyburide. His blood pressure is 100/80 mmHg, and heart rate is 90/min. Physical examination is significant for a harsh crescendo-decrescendo type murmur that is heard at the base of the heart and radiates to the carotids. ECG reveals left ventricular hypertrophy and secondary ST segment and T wave changes. Echocardiography shows concentric left ventricular hypertrophy with severe calcification of the aortic valve. The aortic valve area is 0.78 cm2, and the trans-valvular gradient is 50 mmHg. Which of the following is the best statement about this patient’s condition?
