Hemodynamic Implications of Transcatheter Tricuspid Valve Repair in HFpEF Patients

Inclusion Criteria: * Severe tricuspid regurgitation with need for interventional treatment approach as decided by an interdisciplinary heart team. * Signs and symptoms of left-sided heart failure. * Left-ventricular ejection fraction ≥50% * Invasive evidence of elevated left-ventricular fillings pressures (pulmonary capillary wedge pressure \[PCWP\] or left-ventricular end-diastolic pressure ≥15 mmHg) Exclusion Criteria: * Concomitant relevant mitral valve regurgitation with need for concomitant interventional treatment * Moderate aortic stenosis. * Pregnancy * Contraindication to perform cardiac magnetic resonance imaging. * Conditions rendering patient unable to give informed consent to the study protocol.
