Retraction of: Exercise pulmonary hypertension by the mPAP/CO slope in primary mitral regurgitation

This is a retraction of: Sebastiaan Dhont, Jan Stassen, Lieven Herbots, Sarah Hoedemakers, Youri Bekhuis, Ruta Jasaityte, Sarah Stroobants, Thibault Petit, Elise Bakelants, Maarten Falter, Sara Moura Ferreira, Guido Claessen, Petra Nijst, Pieter M Vandervoort, Philippe B Bertrand, Jan Verwerft, Exercise pulmonary hypertension by the mPAP/CO slope in primary mitral regurgitation, European Heart Journal - Cardiovascular Imaging, Volume 25, Issue 4, April 2024, Pages 530–538, https://doi.org/10.1093/ehjci/jead313

After careful deliberation, this paper is being retracted by the authors and the journal. Significant errors were identified by the authors in the outcome data collection and statistical analysis of a secondary outcome endpoint. Correction of all errors showed that the overall conclusions of the manuscript — mPAP/CO slope as an independent predictor of outcome— were not affected. However, the extent of the required corrections to the original manuscript is substantial. Therefore, the authors and the journal have mutually agreed that retraction is the most appropriate course of action.

The authors sincerely apologize for any inconvenience caused to readers, reviewers, and the broader scientific community.
