Advances in aortic stenosis diagnosis and treatment are improving patient outcomes. Symptomatic patients benefit from surgery, while asymptomatic individuals typically do not require intervention.

Area of Science:

  • Cardiology
  • Valvular Heart Disease

Background:

  • Aortic stenosis is increasingly caused by bicuspid valves and calcification in the elderly, replacing rheumatic causes.
  • Prognosis is linked to symptoms: angina (3-5 years survival), syncope (3 years), and heart failure (12-24 months).

Purpose of the Study:

  • To review recent advances in the understanding, diagnosis, and treatment of aortic stenosis.
  • To highlight the prognostic significance of symptoms and current treatment indications.

Main Methods:

  • Noninvasive diagnosis has improved with two-dimensional and Doppler echocardiography, estimating valve area and pressure gradients.
  • Cardiac catheterization remains essential for coronary artery anatomy assessment before surgery.
  • Catheter balloon valvuloplasty is a new treatment option showing early promise.

Main Results:

  • Echocardiography provides accurate noninvasive assessment of aortic stenosis severity.
  • Symptomatic patients generally require surgical intervention, irrespective of left ventricular function.
  • Catheter balloon valvuloplasty offers a less invasive option with preliminary positive results.

Conclusions:

  • Aortic stenosis management has evolved with improved diagnostic tools and therapeutic options.
  • Timely surgical intervention is crucial for symptomatic patients.
  • Catheter balloon valvuloplasty is a promising, albeit still evaluated, treatment modality.
