Korea VHD Echo Study: Real-World Practice of Aortic, Mitral, and Tricuspid Valves

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a multicenter, retrospective observational study using echocardiography and EMR data from 2010 to 2020 to describe real-world burden, progression, and treatment pathways for moderate to severe native valvular heart disease. Adults with at least two echocardiograms will be included, while those with congenital disease or prior valve surgery at baseline are excluded. The analysis will focus on severity at baseline, rate of progression, time to interventions (such as surgery or transcatheter procedures), and referral patterns across tertiary centers in Korea.
