RESUMO
Transesophageal echocardiography (TEE) has been extensively used historically for Transcatheter aortic valve implantation (TAVI) but focus is shifting from routine use of TEE and general anesthesia to "as needed" use. We evaluated patients who had TAVI in our institution from September 2012 to February 2017. Decision for implantation and use of TEE during procedure was made by the structural heart team on a case-to-case basis, based on FDA approved indications. Data including procedural details, length of stay and rehospitalizations were obtained from all patients. TAVI was performed on 178 patients during the study period of which 104 of 178 had TEE during TAVI. Baseline characteristics were fairly comparable in both groups. Similar proportion of self-expanding and balloon expanding valves were deployed. Patients in TEE group had longer overall procedure time (107 minute vs 83 minute, p = 0.0002) and longer length of stay (5.01days vs 2.49days, p < 0.0001). Echocardiographic study postprocedure showed similar incidence of paravalvular leak and similar gradients and velocities across aortic valve. Rates of 30-day readmissions were similar in both groups. In conclusion, in this single-center retrospective analysis-TAVI without the 'routine use' of TEE was comparable with those done with TEE guidance in terms of periprocedural complications and 30-day readmissions. Overall procedure length and length of stay was predictably higher in the TEE group.
