About this study

The aim of PLUTO-II is to use biventricular pressure-volume (PV) loop measurements to improve the understanding of direct changes in cardiac and hemodynamic physiology induced by transcatheter aortic valve implantation (TAVI) or tricuspid edge-to-edge repair (TEER). These procedures evoke immediate changes in cardiac mechanoenergetics, ventricular-vascular interaction as well as ventricular (in)dependency. Within the context of PLUTO-II, patients will undergo biventricular PV-loop measurements before and after TAVI or TEER. In future, the application of perprocedural PV loop monitoring may tailor the daily individual decision making process during structural interventions in the catheterization laboratory.

Read the detailed description

Pressure-Volume (PV) loop monitoring is a tool allowing direct visualization of individual cardiac and hemodynamic physiology, including parameters reflecting cardiac mechanoenergetics (a derivative of the myocardial metabolic demand) as well as the ventricular-arterial coupling. The concepts of changing biventricular cardiac and hemodynamic physiology induced by structural heart interventions, including Transcatheter Aortic Valve Implantation (TAVI), Transcatheter Edge-to-Edge Mitral Repair (mitral TEER) and Transcatheter Edge-to-Edge Tricuspid Repair (tricuspid TEER) are largely based on hypotheses, computer simulations and non-invasive (echocardiographic) estimations. PVL monitoring has the potential to identify unique characteristics of TAVI, mitral TEER and tricuspid TEER from the perspective of changing baseline cardiovascular physiology, including (a change in) interference between both ventricles (i.e. the ventricular crosstalk). Perprocedural (biventricular) PV loop monitoring can be of direct clinical relevance by appreciating the ventricular tolerance of increased cardiac afterload induced by the particular intervention in individual patients. In future, real-time PV loop analysis can be adjunctive to the individual decision-making process during routine structural interventions.
