“…CMR enables accurate and reproducible measurements of ventricular volumes and pulmonary blood flow to be made in patients with congenital heart diseases (1,4,8,(19)(20)(21)(22)(23). For the last several years, an emphasis in CMR has been placed on PR overshadowing the study of RVOTO.…”

Purpose: To compare right ventricular (RV) size and function between patients with combined pulmonary regurgitation (PR) plus RV outflow tract (RVOT) obstruction (RVOTO) and patients with isolated PR. Materials and Methods:Consecutive individuals with significant PR (PR fraction !20%) after tetralogy of Fallot (TOF) repair who underwent cardiovascular magnetic resonance (CMR) were included. Patients with additional hemodynamic abnormalities (residual ventricular septal defect, extracardiac shunt, and/or more than mild regurgitation at a valve other than the pulmonary valve) were excluded. Significant RVOTO was defined as peak gradient across RVOT !30 mmHg.Results: Significant differences between patients with combined PRþRVOTO (n ¼ 9) and isolated PR (n ¼ 33) were observed in RV end-diastolic volume (138.6 6 25.1 vs. 167.0 6 34.6 mL/m 2 , P ¼ 0.02, respectively), RV endsystolic volume (65.0 6 9.6 vs. 92.7 6 26.2 mL/m 2 , P ¼ 0.003), and RV ejection fraction (RVEF) (52.8 6 3.7 vs. 45.0 6 6.4%, P ¼ 0.001). Both PR and peak RVOT gradient were independent predictors of RV size. Conclusion:Patients with combined PRþRVOTO had smaller RV volumes and higher RVEF when compared with patients with isolated PR. The confounding effect of RVOTO on RV size and function needs to be considered in CMR studies evaluating patients after TOF repair.

“…MRI offers important advantages over other imaging modalities in the study of congenital heart diseases: its high spatial and temporal resolution allow extremely accurate rendering of morphological and functional details, whereas its multiplanar capabilities and large field of view afford a panoramic view with unlimited access to thoracic and extrathoracic structures [11]. These properties, in particular, noninvasiveness and high reproducibility of parameters, make MRI ideal for the evaluation of congenital cardiovascular malformations, also in consideration of the progressive evolution of the characteristics of the study population [2,12].…”

“…La RM possiede alcuni significativi vantaggi rispetto alle altre metodiche d'imaging nella valutazione delle anomalie congenite cardiovascolari: fornisce il dettaglio morfologico e funzionale con estrema accuratezza, in virtù dell'elevata risoluzione spaziale e temporale delle sue sequenze, mentre la multiplanarità e l'ampio campo di vista le consentono una visione panoramica senza limiti di accesso alle strutture toraciche ed extratoraciche [11]. Queste caratteristiche, e in particolare la non invasività e l'elevata riproducibilità dei parametri, la rendono una metodica ideale per lo studio delle cardiopatie congenite, considerando la progressiva evoluzione delle caratteristiche della popolazione di studio [2,12].…”

The substantial advances in the medical and surgical treatment of congenital heart diseases have dramatically improved patients' life expectancy, as well as increased the number of those needing lifelong monitoring to identify complications and residual defects. Magnetic resonance imaging (MRI) is an ideal imaging modality for the follow-up of these young patients owing to its noninvasiveness, high reproducibility and morphological and functional accuracy. This paper describes the most appropriate MRI techniques and sequences for the study of cardiovascular heart diseases on the basis of an analysis of MRI studies carried out between January 2003 and June 2006 on 274 patients affected by all of the main congenital cardiovascular malformations, as well as a review of the literature. The advantages of MRI with respect to other imaging techniques, the problems encountered and the main clinical applications and indications of MRI, with special reference to the most common disease entities, are then discussed to define the role, the utility and the future perspectives of this imaging technique in the study of congenital heart diseases.

“…EKG gated, cine MRI imaging allows anatomic and functional data collection throughout the cardiac cycle. Its analysis is not encumbered by the geometric assumptions inherent in echocardiography [7][8][9][10]. Furthermore, phase contrast (velocity encoding) cardiac MRI data, validated by in vitro phantom data and in vivo cardiac catheterization studies, can provide information about blood flow, allowing accurate determination of valvular regurgitation and shunt volume (Qp:Qs determination) [10][11][12][13][14].…”

The incidence of congenital heart disease is approximately 4-6 per 1000 new births; however, the number of people living with congenital heart disease (CHD) is increasing, because of improved diagnosis, medical, and surgical management. While echocardiography continues to be the mainstay of non-invasive imaging, cardiac MRI (cMRI) and computed tomography (CT) have taken on increasing roles in the diagnosis of congenital heart disease in infants, children, and importantly, adults who may have limited echocardiographic windows, especially if post-operative. Cardiac MRI and multi-slice CT can complement the diagnostic information obtained by echocardiography and invasive cardiac catheterization. Post-operative imaging of CHD is especially enhanced by the spin echo MRI techniques, while gradient cine echo MRI imaging allows functional information that is not encumbered by geometric assumptions. Phase contrast (velocity encoding) cardiac MRI data can provide information about flow, allowing accurate determination of regurgitation and shunt volume. Gadolinium enhanced cMRI or three-dimensional reconstructed images from multi-slice CT angiography allow excellent delineation of vascular structures in complex heart disease. Coronary imaging, while possible with both modalities, appears more facile with fast CT imaging. This article reviews the literature to provide an assessment of the special techniques and considerations needed during the conduct of cardiac MRI/MRA and multi-slice CT examinations during the diagnosis of congenital heart disease in pediatric and adult patients.
