Elective versus urgent in-hospital transcatheter aortic valve implantation.

Background: Transcatheter aortic valve implantation (TAVI) is maturing as a treatment option and is now often undertaken during an unscheduled index hospital admission. The aim of this study was to look at procedural and mid-term outcomes of patients undergoing elective versus urgent in-hospital transcatheter aortic valve implantation.
Methods: We identified a total of 1,157 patients who underwent TAVI between November 2007 and November 2019 at the Sussex Cardiac Centre in the UK. We compared the demographics, procedural outcomes, 30-day and 1-year mortality between elective and urgent patients. Emergency and salvage TAVI cases were excluded.
Results: Of the 1,157 patients who underwent the procedure, 975 (84.3%) had elective while 182 (15.7%) had urgent TAVI. Predominant aortic stenosis was more frequent in elective patients (91.7% vs. 77.4%); p < .01), while predominant aortic regurgitation was seen more commonly in the urgent group (11.5% vs. 4.2%; p < .01). Implantation success was similar between the elective (99.1%) and urgent group (99.4%). In-hospital (1.65% vs. 1.3%: p .11), 30 day (3.5% vs. 3.3%: p .81) and 1 year (10.9% vs. 11%; p .81) mortality rates were similar in the elective and urgent groups, respectively.
Conclusions: In contemporary practice, urgent TAVI undertaken on the index admission can be performed at similar risk to elective outpatient TAVI.
