Navigating upstream and downstream: Unleashing the prognostic potential of RVFWLS/PASP ratio in severe tricuspid regurgitation

The right ventricle (RV) has been the neglected sibling of the left ventricle (LV) for many years. While the LV has historically garnered most of the attention and research focus, in recent years there is a growing recognition of the pivotal role played by the right ventricle, and the interaction with tricuspid regurgitation (TR).
