The Rocking Right Ventricle Paradigm

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...

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 ...

Where is the right ventricle?

To cite: Oylumlu M, Dogan A, Ercan S, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2013-202760 DESCRIPTION A 20-year-old man with no history of known cardiac disease was admitted with dyspnoea on exertion during a few weeks. His effort capacity was class I. At physical examination, his blood pressure was 120/ 70 mmHg and pulse 80 bpm. His physical exami...

Left Ventricle: Role of the Pericardium and the Right Ventricle

IN CHRONIC CARDIAC DISEASE, the left ventricular diastolic pressure does not provide a reliable guide to the diastolic left ventricular volume,' and measurement of chamber volume, shape and wall thickness are necessary to identify changes in the myocardial stress-strain relation.' Under acute conditions, the stiffness of the left ventricular chamber progressively increases as passive diastolic ...
