Intraoperative Transesophageal and Postoperative Transthoracic Echocardiographic Evaluation of a Mechanical Heart Valve Prosthesis Implanted at Aortic Position
2018, Journal of Cardiothoracic and Vascular AnesthesiaCitation Excerpt :The altered loading conditions and hemodilution in the post-CPB period produce variations in the stroke volume ejected across the prosthetic valve that significantly changes the Doppler velocities and pressure gradients. Hence, reliability of these flow-dependent parameters to represent the true prosthetic valve function has been questioned by different authors.16,17 In this study, the authors maintained a constancy of hemodynamic conditions during TEE examination in the post-CPB period.

2007, Journal of Thoracic and Cardiovascular SurgeryCitation Excerpt :We showed a low incidence of regurgitation through the valve in agreement with other authors,18,20 although this was no different from the regurgitation through the Toronto valve.23 Previous work has shown a slightly higher incidence of regurgitation through the Toronto valve.24-27 The incidence of paraprosthetic regurgitation was higher for the Cryolife O’Brien valve than for the Toronto valve, although this difference did not attain statistical significance.

2022, Seminars in Thoracic and Cardiovascular SurgeryCitation Excerpt :However, this report may also suggest that, even though stentless valves may be technically more challenging to implant and have longer perfusion and ischemic times, stentless valve surgery may achieve acceptable morbidity and mortality after ARR, compared to stented valve-graft conduits. Prior reports describe larger EOA, reduced transvalvular gradients, and enhanced regression of LV mass in patients with stentless valves compared to stented valves.36-39 However, some reports were unable to detect these short-term hemodynamic differences.18,35
