Abstract
Summary
V
alve replacement still remains the mainstay surgical therapeutic option for patients with valvular heart disease. Unfortunately, to date, no prosthetic valve meets the criteria of the ideal valve that mimics a normal native valve, and each of the currently available prosthetic valves has inherent limitations.
Both CardiaMed valve and CarboMedics valve are bileaflet mechanical valve prosthesis of different designs. The CarboMedics is one of the most frequently implanted mechanical heart valve prosthesis worldwide. It has an extremely durable design with excellent hemodynamic function. The CardiaMed valve has multiple design features that is claimed to promote effective hemodynamics.
This study aims to compare the early postoperative hemodynamic function and major clinical events in patients receiving CarboMedics valve & CardiaMed valve in Aortic position.
In this study, sixty patients of aortic valve disease patients who were scheduled for elective AVR at Ain Shams University Hospitals. These patients were randomly assigned into 2 groups: Group A: 30 patients received CarboMedics bileaflet mechanical valve; Group B: 30 patients received CardiaMed bileaflet mechanical valve. Exclusion criteria were: Patients in congestive heart failure, Preoperative infective endocarditis, coexistent condition with significant mortality, Emergency operation ,Redo-operation and patients with associated coronary disease.
Preoperative variables include age, gender, body surface area, NYHA class and echocardiographic data.
Intraoperative variables include valve size used, pacemaker usage, cardiopulmonary bypass and aortic cross clamp times.
Postoperative variables include, ICU time, hospital stay, postoperative complications and echocardiography with valve function assessments.
Results: There were no hospital mortalities in either group. There were 10 female patients in group A and 9 female in group B. The age distribution was 48.6±15.2 years for group A and 45.5±15.56 years for group B. The BSA was 1.76±0.18 and 1.73±0.17 respectively. There was no statistical significance between the two groups regarding demographic data, clinical presentation and preoperative risk factors. Preoperative echocardiographic assessment showed no significant statistical difference (P>0.05) between the two groups regarding EDD, ESD, EF, LAD, PASP, or aortic valve pathology.
There was no significant difference in the aortic cross clamp time, total bypass time. The total ICU stay and Total hospital stay were 2.1±2.5 days and 7.5±1.6 days respectively in group A while in the group B they were 2.01±0.5 days and 8.2±2.4 days respectively with no statistical significance between the two groups.
