Identifying patients likely to be readmitted after transcatheter aortic valve replacement

Area of Science:

• Cardiology
• Healthcare Management

Background:

• Hospital readmission after transcatheter aortic valve replacement (TAVR) significantly increases healthcare costs.
• Readmission rates post-TAVR can reach 17.4% at 30 days and 53.2% at 1 year.

Purpose of the Study:

• To identify key patient and procedural predictors of hospital readmission following TAVR.
• To highlight the common causes of readmission and inform prevention strategies.

Main Methods:

• Review of existing literature on TAVR readmissions.
• Analysis of patient demographics, comorbidities, procedural details, and post-TAVR complications as predictors.

Main Results:

• Common predictors include non-transfemoral access, kidney impairment, chronic lung disease, left ventricular dysfunction, atrial fibrillation, bleeding, and prolonged hospitalization.
• Novel predictors identified are new pacemaker implantation and severity of paravalvular and tricuspid regurgitation.
• Non-cardiac causes are more frequent for early readmissions, while cardiac causes, particularly heart failure, are associated with higher mortality.

Conclusions:

• Routine calculation and consideration of readmission risk by heart teams are recommended.
• Holistic approaches addressing non-cardiac readmission causes are necessary for effective prevention.
• Understanding common predictors and causes should guide proactive initiatives to reduce TAVR readmissions.
