Role of Transesophageal Echocardiography in Percutaneous Aortic Valve Replacement with the CoreValve Revalving System
Why the study?
Does transesophageal echocardiography (TEE) provide effective anatomical and functional guidance during percutaneous aortic valve replacement (PAVR) in nonsurgical patients with severe aortic stenosis?
Population
11 nonsurgical patients with severe aortic stenosis and NYHA class III-IV, aged 82 +/- 10 years, undergoing…

Implication
Supports TEE-guided PAVR in severe AS; leaves open generalizability and outcome impact beyond this case.
Structured PICO
Does transesophageal echocardiography (TEE) provide effective anatomical and functional guidance during percutaneous aortic valve replacement (PAVR) in nonsurgical patients with severe aortic stenosis?
P
Population
11 nonsurgical patients with severe aortic stenosis (AS) and NYHA class III-IV, aged 82 +/- 10 years, undergoing percutaneous aortic valve replacement (PAVR).
I
Intervention
Transesophageal echocardiography (TEE) used for initial assessment of native valve/aortic root, procedural guidance, and post-deployment assessment of valve function during percutaneous aortic valve replacement (PAVR).
O
Outcome
Changes in aortic valve (AV) area and left ventricular ejection fraction (LVEF) compared to pre-PAVR baseline, and immediate assessment of prosthetic position and function.surrogate
Transesophageal echocardiography provides critical anatomical and functional guidance, and facilitates the detection of complications during percutaneous aortic valve replacement.
