Summary
This summary is machine-generated.Transcatheter aortic valve implantation (TAVI) waiting times exceed 2.5 months for half of patients, with a 5.8% mortality rate on the waiting list. Impaired renal function and low ejection fraction predict death before TAVI.
Area Of Science
- Cardiology
- Interventional Cardiology
- Healthcare Management
Background
- Growing demand for transcatheter aortic valve implantation (TAVI) strains healthcare capacity.
- Prolonged waiting times for TAVI procedures are a significant concern.
Purpose Of The Study
- To assess TAVI waiting times and mortality rates.
- To identify clinical factors predicting death among patients awaiting TAVI.
Main Methods
- Analysis of 1495 patients referred for TAVI across two French centers.
- Comparison of waiting times and outcomes between TAVI and non-TAVI centers.
Main Results
- Median waiting time was 79 days, longer in non-TAVI centers (105 days) vs. TAVI centers (64 days).
- Overall mortality on the waiting list was 5.8%, with most deaths cardiovascular.
- Impaired renal function and left ventricular ejection fraction <50% independently predicted death.
Conclusions
- Over half of patients wait more than 2.5 months for TAVI, with increasing delays.
- Approximately 1 in 20 patients die while awaiting TAVI, often within two months.
- Renal dysfunction and reduced ejection fraction are critical risk factors for pre-TAVI mortality.
