Key result
Aortic valve neocuspidization (Ozaki procedure) resulted in no postoperative aortic stenosis, 20.8% mild and 4.16% moderate aortic insufficiency, and a mean transvalvular gradient of 7.96 mmHg.
Why the study?
The study aimed to evaluate the importance and results of intraoperative TEE and postoperative TTE for aortic valve functions in patients undergoing the Ozaki procedure.
Does intraoperative TEE and postoperative TTE effectively evaluate early outcomes and hemodynamics in patients undergoing aortic valve neocuspidization?
Observational (n=50)
No
Does intraoperative TEE and postoperative TTE effectively evaluate early outcomes and hemodynamics in patients undergoing aortic valve neocuspidization?
Intraoperative TEE and postoperative TTE are essential for evaluating the early hemodynamic success of aortic valve neocuspidization, demonstrating significant reductions in transvalvular gradients and low rates of moderate aortic insufficiency.
Answers are grounded in this paper and cite their sources.
Supports early hemodynamic success of Ozaki procedure on TEE/TTE; leaves open durability and randomized comparisons.
Aim: This study aims to evaluate the importance and results of intraoperative transesophageal echocardiography (TEE) and postoperative transthoracic echocardiography (TTE) for aortic valve functions in patients undergoing aortic valve neocuspidization (Ozaki) procedure. Material and Methods: In this study, 50 patients with aortic insufficiency, aortic stenosis, or combined aortic pathology, who underwent aortic neocuspidization in our center between 1 January -1 October 2021 were prospectively evaluated with intraoperative TEE as well as preoperative and postoperative TTE. Results: None of the patients had aortic stenosis after surgery. Ten patients (%20,8) had mild, and 2 patients (%4,16) had moderate aortic insufficiency. Mean transvalvular aortic gradient was 7.96(3-16) mmHg, peak transvalvular aortic gradient was 17.04(8-30) mmHg. Peak aortic velocity was 1.66(08-2.6) m/s. Discussion: Intraoperative TEE and postoperative TTE can help evaluate early outcomes of aortic valve neocuspidization. TTE and TEE are necessary for intraoperative and postoperative management of hemodynamics of patients.

A 2022 study conducted an observational in Aortic valve pathologies (aortic stenosis, aortic insufficiency, or combined) (n=50). Aortic valve neocuspidization (Ozaki procedure) was evaluated on Postoperative aortic valve function (aortic stenosis, aortic insufficiency, transvalvular gradients). Aortic valve neocuspidization (Ozaki procedure) resulted in no postoperative aortic stenosis, 20.8% mild and 4.16% moderate aortic insufficiency, and a mean transvalvular gradient of 7.96 mmHg.
