About the trial
What the trial wants to find out
This prospective, single-center observational study aims to evaluate the relationship between changes in aortic valve hemodynamics and pulmonary congestion in patients undergoing elective transfemoral transcatheter aortic valve implantation (TAVI) for severe symptomatic aortic stenosis. Pulmonary congestion will be assessed non-invasively using lung ultrasound, with particular emphasis on B-lines, at predefined time points before and after TAVI. Changes in aortic valve area and other echocardiographic parameters will be evaluated in relation to changes in lung ultrasound findings. The primary objective is to determine the association between improvement in aortic valve area following TAVI and changes in pulmonary congestion.
The group in the trial
- TAVI Cohort
Patients with severe symptomatic aortic stenosis undergoing elective transfemoral transcatheter aortic valve implantation (TAVI) as part of routine clinical care. Lung ultrasound and echocardiographic assessments will be performed at predefined time points to evaluate changes in pulmonary congestion and aortic valve hemodynamics.
Treatment: Transcatheter Aortic Valve Implantation (TAVI)
