Exercise echocardiography in aortic stenosis with preserved ejection fraction.

Area of Science:

• Cardiology
• Cardiovascular Imaging
• Valvular Heart Disease

Background:

• Asymptomatic aortic stenosis management remains controversial, necessitating effective risk stratification.
• Multimodality imaging, particularly exercise stress echocardiography, is crucial for assessing these patients.
• Left ventricular ejection fraction preservation is common in moderate to severe aortic stenosis.

Purpose of the Study:

• To review the utility of exercise echocardiography in asymptomatic patients with moderate to severe aortic stenosis.
• To guide the timing of intervention and follow-up strategies based on exercise echocardiography findings.

Main Methods:

• Focus on exercise echocardiography protocols for asymptomatic aortic stenosis.
• Evaluation of key echocardiographic parameters during exercise stress.
• Review of multimodality imaging approaches in conjunction with exercise echocardiography.

Main Results:

• Exercise echocardiography provides valuable prognostic information in asymptomatic aortic stenosis.
• Specific exercise-induced parameters can identify patients at higher risk.
• This imaging modality aids in differentiating between stable and progressing disease.

Conclusions:

• Exercise echocardiography is a key tool for risk stratification in asymptomatic aortic stenosis.
• Its findings are instrumental in guiding the timing of surgical or interventional procedures.
• Optimized follow-up protocols can be established based on exercise echocardiography results.
