Follow-up
The most recent clinical information was obtained by calling the patient or the referring cardiologists. The median clinical follow-up was 41 (20-64) months. The average number of echocardiographic studies at follow up for patients was 1.5, but we reported the last one in all cases but when TR moderate-or-more was recorded. In those cases, the first echocardiogram reporting recurrence was collected. The median echocardiographic time was 35(18-58). Follow-up ended in December 2016.
