Effects of a Cloud-Based Synchronous Telehealth Program on Valvular Regurgitation Regression: Retrospective Study

Area of Science:

• Cardiology
• Digital Health
• Medical Informatics

Background:

• Telemedicine is linked to improved cardiovascular outcomes.
• The impact of telemedicine on the regression of mitral regurgitation (MR) and tricuspid regurgitation (TR) is not well understood.

Purpose of the Study:

• To assess if telemedicine facilitates MR and TR regression compared to usual care.
• To determine if telemedicine is associated with improved patient survival.

Main Methods:

• Retrospective cohort study of patients with moderate or greater MR or TR (2010-2020).
• Telehealth group received remote monitoring of daily biometrics; non-telehealth group received usual care.
• Primary endpoint: regression of MR/TR from moderate or greater to less than moderate severity.

Main Results:

• Telehealth participation was robustly associated with MR regression (HR 2.20, P=.001).
• MR regression correlated with reverse cardiac remodeling (improved LVEF, reduced LV/LA dimensions).
• Telehealth was a univariable determinant for TR regression (P=.05).

Conclusions:

• Telemedicine significantly enhances the probability of MR regression.
• MR regression is associated with better survival and reverse cardiac remodeling.
• Findings suggest telemedicine integration into future cardiovascular care guidelines.
