Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

RV and LV ejection fraction assesment

Arm Description

assesment RV and LV ejection fraction after PVR measured by MRI

Outcomes

Primary Outcome Measures

determination of the quantity of diffuse myocardial fibrosis

5. Study Description

Brief Summary
Long term survival of patients with repaired tetralogy of Fallot is excellent (about 85% at 35 year-old). However these patients are exposed to residual pulmonary stenosis (PS) and/or pulmonary regurgitation (PR). It is well established that these lesions can lead to irreversible sequelae such as right ventricle dilatation and dysfunction. Pulmonary valve replacement technique was developed to avoid long term right ventricular dysfunction. Pulmonary valve replacement indications are based upon the presence of symptoms at exercise and/or morphological or functional parameters such as severe pulmonary regurgitation with right ventricle dilatation/dysfunction. The best timing of such intervention is still underdebate with the main aim of having the right balance between avoiding long term sequelae of PR or PS and being the latter possible to push ahead the need for new intervention. Recent publication showed that myocardial diffuse fibrosis can contribute to irreversible alteration of myocardial contractility. Quantification of diffuse fibrosis by magnetic resonance imaging is feasible and could help the physician to best determine the right timing for PVR in this population of patients. Cardiac function assessment at rest and during exercise is possible using MR and our centre has developed a program for cardiac exercise during MRI. This could help to detect infra clinic abnormality and to analyse myocardial adaptation during exercise.
