Key result
Echocardiography monitoring during TAVR is linked to ~95% procedural success and minimal paravalvular leak.
Why the study?
To investigate the clinical value of echocardiography across preoperative assessment, intraoperative monitoring, and postoperative follow-up in patients with aortic valve disease undergoing TAVR.
Does echocardiography provide clinical value in the perioperative management of patients undergoing TAVR?
Observational (n=158)
Does echocardiography provide clinical value in the perioperative management of patients undergoing TAVR?
Echocardiography is valuable for preoperative assessment, intraoperative guidance, and postoperative follow-up in TAVR, showing good agreement with MSCT and aiding in reducing paravalvular leakage.
Supports echocardiography in TAVR perioperative care; leaves open need for RCTs to confirm benefit.
Objective: To investigate the clinical value of echocardiography in the preoperative assessment, intraoperative monitoring, and postoperative follow-up of patients with aortic valve disease (AVD) undergoing transcatheter aortic valve replacement (TAVR). Materials and Methods: This retrospective study included clinical data of 158 patients with AVD who underwent TAVR. Patients were divided into three groups based on the type of AVD. The perivalvular structure of the patient was evaluated preoperatively using echocardiography and compared with multi-slice computed tomography (MSCT) measurements. Echocardiography was used to dynamically monitor the entire surgical process. Each patient was followed up for 1 month. Results: The success rate of TAVR was 94.9%. Preoperative measurements of the paravalvular (PVL) structure indicated good agreement between transesophageal echocardiography (TEE) and MSCT. Real-time TEE was used to adjust the location of the artificial valve to reduce leakage before completing TAVR, and the final incidence of moderate and above PVL was 1.3%. Data obtained 1 month after TAVR revealed that both the structure and function of the patient’s heart underwent benign reverse remodeling compared with those before surgery. Conclusion: Echocardiography played an important role in the entire procedure and may provide a basis for evaluating the efficacy and prognosis of TAVR.

Lv et al. (2025) conducted an observational in Aortic valve disease (AVD) undergoing transcatheter aortic valve replacement (TAVR) (n=158). Echocardiography was evaluated on Success rate of TAVR. Echocardiography for assessment and monitoring during TAVR was associated with a 94.9% procedural success rate and a 1.3% incidence of moderate or greater paravalvular leakage.
