Cardiac MRI and Pulmonary MR Angiography of Sinus Venosus Defect and Partial Anomalous Pulmonary Venous Connection in Cause of Right Undiagnosed Ventricular Enlargement

Abstract

This article about cardiac MRI in adults with sinus venosus defect and PAPVC shows that cardiac MRI can reliably detect and quantify these lesions when other methods have not provided a complete diagnosis for the cause of right heart enlargement.

Sinus Venosus Atrial Septal Defect in Adults: Utility of Cardiovascular MRI in resolving this Diagnostic Dilemma

“…It can therefore, help obviate the need for cardiac catheterisation. Our observations with regards to the clinical utility of CMRI for SV-ASD are supported by the results of Kafka and Mohiaddin [15]. They recently reported on a series of 19 patients with SV-ASD who underwent CMRI.…”

“…In all cases, CMRI correctly identified the SV-ASD as well as any associated PAPVD. The authors concluded that CMRI can reliably detect and quantify these lesions when other methods have failed to provide a cause for right heart enlargement [15]. CMRI is also useful for follow-up after surgical repair of these lesions, where TTE windows are frequently suboptimal and also when there is discordance between clinical findings and TTE results.…”

Quantification of wall shear stress using a finite-element method in multidimensional phase-contrast MR data of the thoracic aorta

“…Several numerical procedures have recently been proposed to evaluate flow patterns, determine the wall shear stress (WSS) distribution, and calculate pressure difference maps (Oshinski et al, 1995;Tyszka et al, 2000;Ebbers et al, 2001;Barker et al, 2010;Bock et al, 2010;Bock et al, 2011). These methods have shown the potential of 2D and 3D CINE PC-MRI for assessing different cardiovascular diseases (Wigström et al, 1999;Weigang et al, 2008;Boussel et al, 2009;Kafka and Mohiaddin, 2009;Markl et al, 2010;Cecchi et al, 2011;Frydrychowicz et al, 2011;Francois et al, 2012;).…”

Évaluation de la fonction du ventricule droit par l’imagerie en coupes

“…Il n'est pas rare que l'examen IRM, demandé pour « suspicion de DVD » chez un patient avec cavités droites dilatées en échographie, fasse découvrir une communication interauriculaire (CIA) ou un retour veineux pulmonaire anormal (RVPA) [17]. C'est pourquoi il est de bonne règle de commencer l'examen IRM dans ce contexte par la mesure du rapport de débit Qp/Qs.…”
