Assessing how anesthesia and imaging affect aortic regurgitation evaluation

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to evaluate the effects of different imaging modalities, specifically trans-thoracic echocardiography (TTE) and trans-esophageal echocardiography (TEE), on the assessment of aortic regurgitation severity. Patients scheduled for cardiac surgery who will undergo TEE will be enrolled, and their aortic insufficiency grading will be compared between TTE performed before anesthesia and TEE performed after anesthesia induction. The study seeks to understand how anesthesia and positive pressure ventilation influence echocardiographic results.

Why it matters

Exclusion Criteria:

* Non sinus rhythm
* Mitral regurgitation more than mild.
* Pre-operative critical state (according to the definition of the EuroSCORE II)
* Presence of a prosthetic aortic valve
* Contra-indication to trans-esophageal echo

• Aspirin by itself after TAVR for pure aortic regurgitation

  In people with severe aortic regurgitation who have had TAVR and do not need long-term anticoagulation, this study tests whether aspirin alone for a year is safer and as effective as a short course of warfarin followed by aspirin.
