The efficacy of the remote monitoring system following transcatheter aortic valve replacement.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has become a cornerstone in the management of aortic valve disease. However, delayed complications after hospital discharge and readmission remain in an issue following TAVR. We aimed to evaluate the impact of remote monitoring systems on clinical outcomes after TAVR.

METHODS: All patients who underwent TAVR from September 2014 through January 2019 were included retrospectively. Additionally, all patients, clinically indicated for TAVR from 9/1/2018 through 8/30/2021, were screened, and patients who agreed were prospectively enrolled. Medtronic Care Management Service (MCMS) was used to monitor patients following TAVR after discharge (Medtronic, Minneapolis, MN).

RESULTS: A total of 1078 patients were included. Among them, 843 (78.2 %) patients were discharged with MCMS (MCMS group) and 235 (21.8 %) patients were discharged without (non-MCMS group). Overall, the mean age was 81.5 years, and mean STS-PROM was 5.53 %. Baseline conduction defect was observed in 427 (39.6 %). Peripheral artery disease was more common in the MCMS group while a history of myocardial infarction was more likely seen in the non-MCMS group. After propensity-score matching, length of hospital stays was significantly shorter in the MCMS group (1.42 days vs. 1.82 days in the non-MCMS group, p < 0.001). Readmission rates and new permanent pacemaker insertion rates were similar between the two groups. All-cause mortality, 30-day and 90-day mortality were comparable between the groups.

CONCLUSIONS: MCMS was easily applicable to a clinical practice and may reduce length of hospital stays in patients undergoing TAVR without increasing readmission or mortality.
