EFFICACY OF TTK CHITRA MECHANICAL HEART VALVE VERSUS ST JUDE MECHANICAL HEART VALVE IN AORTIC VALVE REPLACEMENT

Background: For patients having aortic valve replacement (AVR), the St. Jude and TTK Chitra mechanical heart valves are both often utilised in daily practise. The effectiveness of these valves is still up for discussion, though. Therefore, the purpose of this study was to investigate the outcomes of patients who underwent AVR with a St. Jude mechanical valve (SJMV) or a Chitra heart valve prosthesis (CHVP). Methods: We performed a single-center prospective cohort study among patients undergoing isolated aortic valve replacement at the MMC Institute of Cardiology and Cardiothoracic Vascular Surgery in Chennai between January 2022 and June 2023. An aortic valve replacement was necessary in 60 patients in total. Thirty cases underwent AVR with the St. Jude valve and the remaining thirty cases were treated with the TTK Chitra valve. Data were collected and analysis was carried out using the Statistical Package for Social Sciences. Results: Group SJ had 90% of instances with RHD, whereas group C had 93.3% of cases with RHD. In groups SJ and C, calcified AV was observed in 33.3% and 40% of patients, respectively, and bicuspid AV in 26.7% and 23.3% of cases, respectively. Both group SJ and group Cs baseline cardiac parameters were determined to be comparable. Both at baseline and one month after surgery, the mean EF, LVSD, and LVDD in groups SJ and C were comparable. At one month after surgery, both groups mean gradient across the aortic valve was significantly lower than baseline. Groups SJ and C had mortality rates of 6.7% and 3.3%, respectively. Conclusion: Aortic valve replacement patients in low-resource countries can now explore cardiac surgery because to the TTK Chitra mechanical heart valve, which provides comparable results at around half the cost of an imported St. Jude mechanical heart valve with similar efficacy and safety.
