Invasive assessment of aortic stenosis in contemporary practice

Area of Science:

• Cardiology
• Cardiovascular Imaging
• Interventional Cardiology

Background:

• Aortic stenosis diagnosis and management rely on accurate hemodynamic assessment.
• Echocardiography is the primary noninvasive tool, but limitations exist.
• Cardiac catheterization provides direct hemodynamic measurements.

Purpose of the Study:

• To review the role of cardiac catheterization in characterizing aortic stenosis.
• To discuss its clinical applications, limitations, and added value compared to echocardiography.
• To emphasize an integrative approach combining invasive and noninvasive evaluations.

Main Methods:

• Review of current literature on cardiac catheterization and echocardiography in aortic stenosis.
• Discussion of hemodynamic variables beyond transvalvular pressure gradients.
• Analysis of discrepancies between imaging and invasive measurements.

Main Results:

• Cardiac catheterization offers precise hemodynamic data, crucial for complex cases.
• Discrepancies between echocardiography and catheterization can arise and require careful interpretation.
• Hemodynamic assessment includes variables beyond simple pressure gradients.

Conclusions:

• Cardiac catheterization remains valuable for detailed aortic stenosis characterization.
• An integrative approach, combining echocardiography and catheterization, optimizes patient assessment.
• Understanding the interplay between modalities improves clinical decision-making for aortic stenosis.
