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.
