💡 Explanation
## **Core Concept**
The question pertains to the management of a patient with aortic stenosis who undergoes exercise testing according to the Bruce protocol, which is a standardized test used to assess cardiac function under stress. Aortic stenosis is a valvular heart disease characterized by the narrowing of the aortic valve opening, which can impede blood flow from the left ventricle to the aorta.
## **Why the Correct Answer is Right**
The patient's exercise test was stopped due to fatigue, and a regional pressure gradient of 60 mmHg across the aortic valve was noted. This significant gradient indicates severe aortic stenosis. The management of severe aortic stenosis often involves surgical intervention, such as aortic valve replacement (AVR), which can be done through surgical AVR or transcatheter aortic valve replacement (TAVR). The best management option for severe symptomatic aortic stenosis or severe asymptomatic aortic stenosis with evidence of valve-related complications is typically AVR.

- **Option B:** This option is not provided, so it cannot be evaluated.
- **Option D:** This option is not provided, so it cannot be evaluated.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that severe aortic stenosis is defined by a mean gradient ≥50 mmHg or a peak gradient ≥60 mmHg. Patients with severe aortic stenosis who are symptomatic or have left ventricular dysfunction are generally recommended for AVR. Exercise testing in patients with aortic stenosis can help unmask symptoms and guide management but should be performed with caution.
