Transcatheter Aortic Valve Implantation (TAVI) versus Surgical Aortic Valve Replacement (SAVR): A Retrospective Analysis from a Tertiary Care Hospital

Some necessary changes made.

Background Since Pakistan is adapting to the technological advancements in the procedure, and shifting to TAVI, more studies are required to evaluate the safe and efficacy of the procedure. The data on the topic is scarce, and our study will aim to fill in the literature gap. Furthermore, by looking at the burden of cardiac diseases, a policy implementation could be put in place to guide prevention and treatment in the country. We aim to evaluate the efficacy of TAVI procedure and decide whether its a sustainable, cost effective enough of an option when compared to standard open heart surgery in the setting of low and middle income country Results Based on a cohort of 200 patients (100 in each group), a higher Postoperative Complication Rate was observed with SAVR compared with TAVI (39.0% vs 13.0%, respectively).Among SAVR patients the most common complications were postoperative bleeding (51.2%), infection (30.7%) and cardiac tamponade (17.9%).Patients who underwent TAVI had higher incidence of other postoperative complications which were vascular complications (53.8%) and need for pacemaker implantation (46.1%).On comparison the two groups did show significant differences in the mortality rate (SAVR G = 15.0%&TAVI G = 4.0%). Conclusions TAVI has Low Postoperative Complication Rate and Mortality Rate compared to SAVR .Our Data confirm that TAVI is a safer and more reliable procedure for Patients suffering from Aortic Stenosis.
