This year, we introduced a new standardized agreement format to align with current regulatory requirements and streamline data collaboration, the Joint Data Registry Agreement (JDRA). Three tailored JDRA versions have been developed for the HVS Aortic Valve Database, the HVS Aortic Kids Database, and the HVS Mitral Tricuspid Valve Database.

We are pleased to share that most participating centers have confirmed their involvement in the HVS databases, and the JDRA is currently under legal review at many sites. We sincerely thank all centers that are actively reviewing the agreement or who have already signed it.

We are thrilled to announce the approval of a third project within the HVS Mitral Tricuspid Valve Database:

#3 The Effect of Post-repair Mitral Valve Geometry and Function on the Incidence of Recurrent Mitral Regurgitation

Proposal overview:
This project aims to identify both qualitative and quantitative intraoperative post-repair transesophageal echocardiography (TOE) parameters associated with the risk of recurrent mitral regurgitation (rMR). A retrospective nested case-control (NCC) study will be conducted, focusing on patients who underwent surgical mitral valve repair for primary (degenerative) mitral valve disease. The study will assess the occurrence of rMR during early, mid-, and long-term postoperative follow-up, as identified through follow-up transthoracic echocardiography (TTE) and/or TOE.

Inclusion period:
2010 until 2024.

Initiator:
Meindert Palmen, MD, PhD, Nina Ajmone Marsan, MD, PhD, Anton Tomšič, MD, PhD, Bart JA Mertens MD, PhD, Robert J.M. Klautz, MD, PhD from Leiden University Medical Center.

Centers with expertise in these interventions are encouraged to participate.
