“…The quality of the prosthetic valve itself has probably a great deal to do with the improvements that the patients experienced. In vitro and in vivo studies, both invasive and non-invasive, have revealed that the CarboMedics prosthesis has an excellent hemodynamic performance, similar to that of the St. Jude Medical prosthesis [21,22], the first generation bileaftet valve. Although reports of structural deterioration have been described for the St. Jude Medical prosthesis [23,24], however, the worldwide experience with the St. Jude Medical valve is significantly higher and has longer follow-up than with the CarboMedics valve, so only time will tell how the CarboMedics valve will fair in the long run.…”

With the premise of better structural design, easy rotatability and less valve-related complications CarboMedics cardiac prosthesis (CarboMedics, Inc., Austin, Texas) was launched in 1986. We reviewed our experience with 165 implants in a group of mostly rheumatic heart disease patients with a follow-up period of at least seven years and a maximum of ten years. There was no hospital mortality, significant morbidity or thromboembolism and no patient to date has experienced any valve-related event. We conclude that the clinical performance is quite satisfactory and it improves the quality of life in patients with cardiac valve prostheses. We find the rotatability feature is particularly useful especially in situations where the entire mitral apparatus is preserved during mitral valve replacement.

“…33,34 However, several in vivo and in vitro studies showed the discrepancy between the prosthesis size and the hemodynamic profile of the Carbomedics prosthesis. 35,36 Authors found a weak inverse correlation between prosthesis size and transprosthetic gradients and EOA. Probably, overestimation of Doppler examination and underestimation of EOA by the manufacturer may be the reasons for the discrepancy between clinical and instrumental data.…”

Early outcomes of patient-prosthesis mismatch following aortic valve replacement

Introduction: Patient-prosthesis mismatch (PPM) has been associated with numerous short- and long-term adverse events. This study aimed to evaluate the effect of PPM on early postoperative results after aortic valve replacement (AVR) in daily practice. Methods: In this single-centre retrospective study, 150 non-consecutive patients from March 2019 to January 2020 with clinically indicated AVR with/without concomitant surgery were analysed. The study protocol included operative mortality, complication rate, and pre- and postoperative echocardiographic data. PPM was considered severe with indexed effective orifice area at <0.65 cm2/m2, moderate at 0.65–0.85 cm2/m2 and none at >0.85 cm2/m2. Results: Moderate PPM was observed in 16 patients (10.6%). No patient had severe PPM. PPM was not related to early mortality ( r = 0.40, p = 0.630), intra- ( r = −0.076, p = 0.352) and postoperative ( r = −0.0134, p = 0.102) events. Conclusion: In this study, moderate PPM was a frequent finding after AVR, whereas severe PPM was not observed. PPM did not affect the early results after AVR. A long-term follow-up study in a large patient population is required to assess the actual influence of residual PPM.

“…Compared with the earlier ball-and-cage and tilting disc prostheses, the lower-profile bileaflet mechanical valve designs result in improved flow characteristics, lower transvalvular pressure gradients, less blood flow turbulence, improved hemodynamics at a given annular diameter, a larger orifice area, and fewer thromboembolic complications [8,9]. Thus, their advantages are especially important in patients who require a smaller prosthesis.…”

Are all bileaflet mechanical valves equal?

Bileaflet mechanical valves are a valuable option for patients undergoing valve replacement surgery. All of the bileaflet designs provide good hemodynamic performance with long-term durability. However, some designs may provide better hemodynamic profiles in smaller valve sizes. Furthermore, newer models may have a more favorable thromboembolic profile. Nonetheless, the risk of anticoagulant-related complications with mechanical valves must be weighed against the risks of structural deterioration and reoperation of bioprostheses. Ultimately, the choice of prosthesis should be made after careful discussion with the patient, referring cardiologist, and cardiac surgeon.
