Hemodynamic Implications of Transcatheter Tricuspid Valve Repair in HFpEF Patients

Not Applicable

• Conditions: Congestive Heart Failure; Tricuspid Regurgitation

• Registration Number: NCT04782908
• Lead Sponsor: Heart Center Leipzig - University Hospital

Brief Summary

The aim of the study is to investigate the pathophysiological implications of transcatheter tricuspid valve edge-to-edge repair in patient with heart failure and preserved ejection fraction and severe tricuspid regurgitation. Changes in right- and left-ventricular function as well as the interventricular dependence will be analysed on a multimodal basis including pressure-volume loop analysis and cardiac magnetic resonance imaging.

Primary Outcome Measures

Name	Time	Method
Periprocedural change in enddiastolic pressure volume relationship of the left ventricle	Periprocedural.	Change in the ratio of pressure to volume of the left ventricle before and after TTVR. Measurement will take place during TTVR with patient in general anesthesia. Measures will be made using a commercially available conductance catheter. Data analysis will be performed offline using a dedicated software.

Secondary Outcome Measures

Name	Time	Method
Change in the ratio of isovolumetric relaxation constant "Tau" and duration of diastole of the left ventricle.	Periprocedural.	Measurement will take place during TTVR with patient in general anesthesia. Measures will be made using a commercially available conductance catheter. Data analysis will be performed offline using a dedicated software.
Change in dPdtmin	Periprocedural.	Measurement will take place during TTVR with patient in general anesthesia. Measures will be made using a commercially available conductance catheter. Data analysis will be performed offline using a dedicated software.
Change in the estimated left ventricular end diastolic volume at 10 mmHg as estimated by the left ventricular pressure volume relationship (LVEDPVR)	Periprocedural.	Measurement will take place during TTVR with patient in general anesthesia. Measures will be made using a commercially available conductance catheter. Data analysis will be performed offline using a dedicated software.
Change in the early diastolic filling pattern as assessed by MRI.	Baseline and 1-month follow-up following TTVR.	All patients will receive MRI before and 1-month after TTVR on a 1.5 tesla scanner.
