Clinical significance of transesophageal echocardiography during patient selection for transcatheter aortic valve implantation without balloon predilation

Objective To compare the difference in transesophageal echocardiography (TEE) between patients undergoing transcatheter aortic valve implantation (TAVI) with balloon predilation (BPD) and those without BPD, and to evaluate the clinical significance ofTEE during patient selection for TAVI without BPD.Methods TEE data of 149 patients with severe aortic stenosis, who underwentTAVI from January 2016 to January 2019, were retrospectively analyzed. Three-dimensional TEE imaging was used to evaluate the aortic annulus and root, leaflet mobility, degree of calcification, valve area, etc. After TEE data were reviewed, clinical significance of TEEduring patient selection for TAVI without BPD was evaluated.Results The mean age of patients was (82.73±5.26) years. Totally 59 patients underwent TAVI without BPD. The mean aortic valve area was (0.61±0.15) cm2, and the mean aortic annular diameter was (22.14±2.31) mm. A total of 14 patients had peri-valve leakage after TAVI, including 5 patients without BPD . There was no significant difference in peri-valve leakage between the patients who underwent TAVI with BPD and those without BPD. In addition, no significantcomplications were found in other patients.Conclusion TEE is able to accurately measure the aortic structure and better select appropriate patients undergoing TAVI without BPD, which is of great significance for clinical treatment.
