The Right Ventricle: Unforgettable With Imaging

The Right Ventricle: Unforgettable With Imaging.

T he right ventricle has been described as the “forgotten chamber,” and despite better awareness of its importance, current heart failure (HF) guidelines have taken little cognizance of the right ventricle. In part, this reflects the limitations of the evidence regarding the determinants of right ventricular (RV) dysfunction and its relation to outcomes in HF. This special issue of iJACC seeks ...

Imaging of the neglected cardiac chamber: the right ventricle.

Building the right ventricle.

Abnormal development of the arterial pole of the heart underlies a significant fraction of congenital heart defects. Critical steps in arterial pole development are formation of the myocardial outflow tract (or conotruncal region) and its subsequent division into separate left and right ventricular outlets. Division of the cylindrical outflow tract is a complex morphogenetic process driven by c...

Imaging Diagnosis of Right Ventricle Involvement in Chagas Cardiomyopathy

Right ventricle (RV) is considered a neglected chamber in cardiology and knowledge about its role in cardiac function was mostly focused on ventricular interdependence. However, progress on the understanding of myocardium diseases primarily involving the RV led to a better comprehension of its role in health and disease. In Chagas disease (CD), there is direct evidence from both basic and clini...

The Two-Chambered Right Ventricle

THE DIVISION of the right ventricle into two chambers by aberrant, hypertrophied muscular bands is a relatively rare congenital cardiac malformation. No reports have been found that describe the details of anatomic structure and hemodynamics in this anomaly, although Keith, Rowe, and Vlad' and Kjellberg et al.2 alluded to this malformation in their texts. Grant, Downey, and MacMahon3 described ...
