Abstract
Introduction: Pulmonary hypertension (PH) is a common finding in patients with severe aortic stenosis (AS) which are evaluated for transcatheter aortic valve implantation (TAVI).
Aims and objectives: We evaluate whether PH and ECG synchronized CT scan parameters in patients with PH who underwent TAVI are of prognostic significance.
Methods: Patients who underwent TAVI between 2011-2021were included in the study. PH was defined as SPAP>40 mmHg by echocardiography. All patients underwent pre-procedure ECG synchronized CT scan. Clinical, echocardiographic, tomographic and laboratory data were collected retrospectively. Chambers’ volumes were calculated by Philips Portal software ® Pulmonary artery pulsatility was calculated as pulmonary artery (PA) systolic surface area (SA) divided by diastolic PA diastolic SA.
Results: 376 patients were included in the study. The mean age was 80.4±6.96; 56% were females and the mean survival 3.55±1.97 years. Patients with SPAP>40 mmHg had significantly higher mortality then those with SPAP ≤40 mmHg. However, no difference in mortality or number of hospitalization after the procedure. PA pulsatility, PA/aortic root diameter and right ventricle EF did not have significant effect on mortality.
Conclusion: SPAP> 40 mmHg is an independent predictor of mortality after TAVI procedure while ECG synchronized CT scan parameters and PA pulsatility are not.
