Abstract
Title: Comparative study between the ”CardiaMed” (freely floating valve leaflets) vs. ”St.Jude Medical” (freely floating valve leaflets) in mitral valve replacement.
Objective: The purpose of this prospective study is to evaluate the early postoperative hemodynamic function and major clinical events in patients receiving CardiaMed prosthetic valve in comparison to SJM valve in the mitral valve position.
Patients and Methods: 60 patients underwent Mitral valve replacement and followed up from Sept 2013 and Sept 2015 in Ain Shams University hospital. They were divided into two group of 30 patients each, group I, received The CardiaMed valve and group II, received SJM valve. There was no Statistical differences between both groups regarding the demographic data( sex, age and BSA), preoperative clinical status and functional NYHA class, Cardiac assessment regarding left ventricle function and volumes and Mitral valve underlying pathology. Follow up was complete to all patients (100%) at discharge from hospital, 3 months and 6 months postoperative.
Results: By the end of the follow up, we had zero mortality in both groups. as well as There was no valve related co morbidity that necessitates re-surgery. such as valve thrombosis, thromboembolic event, neurological event nor valve endocarditis or prosthetic valve dysfunction. Early postoperative complication was seen, only 4 patients 13.3% in group I, one patient (3.3%) required re-exploration for bleeding, 1 patient(3.3%) rhythm disturbance and two patients (6.7%) had superficial wound infection. The PPG and MPG were slightly higher in group I (10.9±1.2 and 5.3±0.9) than in group II (10.2±2.3 and 5.2±1.3). There was no significant Statistical differences between both groups regarding the postoperative echo follow up data.
Conclusion: Cardiamed freely floating leaflet prosthetic has shown good hemodynamic characteristics. The prosthesis adequately corrects hemodynamic and is safe and no worse than other prostheses. while our recommendation is to avoid usage of the smaller size in comparison to SJM valve prosthesis as the higher incidence of higher PPG and smaller EOA and IEOA in the smaller valve sizes in comparison to SJM bileaflet mechanical valve. While the CardiaMed has advantages regarding the low thrombogenicity and ease in usage in redo surgeries.
