Cardiovascular Magnetic Resonance in patients with repaired Tetralogy of Fallot: the goal standard in preoperative assessment and follow up of injectable pulmonary valve implantation
نویسندگان
چکیده
Background Severe pulmonary regurgitation, progressive dilatation and dysfunction of the right ventricle are the most frequent reason of late morbidity post Fallot repair. Pulmonary valve replacement is often indicated in these patients. BioIntegral Injectable pulmonary valve (IPV) is an innovative less invasive technique, often done off cardiopulmonary bypass (CPB). Cardiovascular Magnetic Resonance (CMR) is fundamental tool to assess patient suitability for IPV insertion and in the clinical follow up.

Right ventricular Hemodynamic Alteration after Pulmonary Valve Replacement in Children with Congenital Heart Disease
Introduction: In patients who underwent surgery to repair Tetralogy of Fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest. Hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. The aim of present study was to assess the effects of pulmonary valve replacement on rig...

Background Total correction of Tetralogy of Fallot (TOF) anomaly in early childhood has been practiced in many centers with good results, but in some of patients after few years sever Pulmonary valve insufficiency occurred. Materials and Methods At a cross- sectional study from January 2015 to January 2016, 10 patients who had history of primary repair of TOF with free pulmonary insufficiency (...

Surgical management of tetralogy of Fallot (TOF) results in anatomic and functional abnormalities in the majority of patients. Although right ventricular volume load due to severe pulmonary regurgitation can be tolerated for many years, there is now evidence that the compensatory mechanisms of the right ventricular myocardium ultimately fail and that if the volume load is not eliminated or redu...

Background Although surgery have improved the prognosis for patients who repaired tetralogy of Fallot (TOF); late ventricular dysfunction, scar and fibrosis remains a problem which weakens the prognosis. Late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) also shows this scar tissue and fibrosis. In these patients decreasing in the right ventricular (RV) ejection fraction ...
متن کاملCorrelation between RVOT sizing and RV function and volumes in patients with repaired tetralogy of Fallot undergoing routine CMR follow-up: is there a better candidate for percutaneous pulmonary valve implantation?
Background CMR is the established non-invasive tool for routine RV functional and morphological assessment in repaired tetralogy of Fallot (rTOF) patients. 3D anatomical data of the RVOT are routinely performed to better address indications for Pulmonary Valve Replacement (PVR), either surgical or percutaneous. The aim of this crosssectional analysis is to improve the ability of CMR to identify...
