Cardiac Magnetic Resonance and the Need for Routine Cardiac Catheterization in Single Ventricle Patients Prior to Fontan: A Comparison of 3 Groups

This study investigated whether cardiac magnetic resonance (CMR) and echocardiography (echo) can replace catheterization (cath) for routine evaluation prior to Fontan and under what circumstances CMR and cath are used together. Routine cath prior to Fontan has been utilized for years; noninvasive methods, however, may be sufficient. This study reviews clinical data in 119 consecutive patients investigating 3 groups: those who underwent CMR alone...
