Impact of wait times on late postprocedural mortality after successful transcatheter aortic valve replacement.

ABSTRACT: Wait times are associated with mortality on waiting list for transcatheter aortic valve replacement (TAVR). Whether longer wait times are associated with long term mortality after successful TAVR remains unassessed. Consecutive patients successfully treated with elective TAVR in our center between January 2013 and August 2019 were included. The primary end point was one-year all-cause mortality. TAVR wait times were defined as the interval from referral date for valve replacement to the date of TAVR procedure. A total of 383 patients were included with a mean wait time of 144.2 ± 83.87 days. Death occurred in 55 patients (14.4%) at one year. Increased wait times were independently associated with a relative increase of 1-year mortality by 2% per week after referral (Adjusted Hazard Ratio 1.02 [1.002-1.04]; p = 0.02) for TAVR. Chronic kidney disease, left ventricular ejection fraction ≤ 30%, access site and STS score were other independent correlates of 1-year mortality. Our study shows that wait times are relatively long in routine practice and associated with increased 1-year mortality after successful TAVR. Such findings underscore the need of strategies to minimize delays in access to TAVR.

Project description:ImportanceReducing postprocedural stroke is important to improve the safety of transcatheter aortic valve replacement (TAVR).ObjectiveThis study evaluated the trends of stroke occurring within 30 days after the procedure during the first 5 years TAVR was used in the United States, the association of stroke with 30-day mortality, and the association of medical therapy with 30-day stroke risk.Design, setting, and participantsRetrospective cohort study including 101 430 patients who were treated with femoral and nonfemoral TAVR at 521 US hospitals in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapies Registry from November 9, 2011, through May 31, 2017. Thirty-day follow-up ended June 30, 2017.ExposuresTAVR.Main outcomes and measuresThe rates of 30-day transient ischemic attack and stroke were assessed. Association of stroke with 30-day mortality and association of antithrombotic medical therapies with postdischarge 30-day stroke were assessed with a Cox proportional hazards model and propensity-score matching, respectively.ResultsAmong 101 430 patients included in the study (median age, 83 years [interquartile range {IQR}, 76-87 years]; 47 797 women [47.1%]; and 85 147 patients [83.9%] treated via femoral access), 30-day postprocedure follow-up data was assessed in all patients. At day 30, there were 2290 patients (2.3%) with a stroke of any kind (95% CI, 2.2%-2.4%), and 373 patients (0.4%) with transient ischemic attacks (95% CI, 0.3%-0.4%) . During the study period, 30-day stroke rates were stable without an increasing or decreasing trend in all patients (P for trend = .22) and in the large femoral access subgroup (P trend = .47). Among cases of stroke within 30 days, 1119 strokes (48.9%) occurred within the first day and 1567 (68.4%) within 3 days following TAVR. The occurrence of stroke was associated with a significant increase in 30-day mortality: 383 patients (16.7%) of 2290 who had a stroke vs 3662 patients (3.7%) of 99 140 who did not have a stroke died (P < .001; risk-adjusted hazard ratio [HR], 6.1 [95% CI, 5.4-6.8]; P < .001). After propensity-score matching, 30-day stroke risk was not associated with whether patients in the femoral cohort were (0.55%) or were not (0.52%) treated with dual antiplatelet therapy at hospital discharge (HR, 1.04; 95% CI, 0.74-1.46) nor was it associated with whether patients in the nonfemoral cohort were (0.71%) or were not (0.69%) treated with dual antiplatelet therapy (HR, 1.02; 95% CI, 0.54-1.95). Similarly, 30-day stroke risk was not associated with whether patients in the femoral cohort were (0.57%) or were not (0.55) treated with oral anticoagulant therapy at hospital discharge (HR, 1.03; 95% CI, 0.73-1.46) nor was it associated with whether patients in the nonfemoral cohort were (0.75%) or were not (0.82%) treated with an oral anticoagulant (HR, 0.93; 95% CI, 0.47-1.83).Conclusions and relevanceBetween 2011 and 2017, the rate of 30-day stroke following transcatheter aortic valve replacement in a US registry population remained stable.
