A 10-day-old neonate with pulmonary consolidation was referred for echocardiography to rule out CHD. At first glance, the morphology appeared to be a bipartite right ventricle with normal tricuspid and pulmonary valves. In-depth analysis, however, of the images showed a double-chambered right ventricle, in which the inlet and outlet portions of the right ventricle were isolated from the apical component of the right ventricle, which itself communicated with the left ventricle through a ventricular septal defect. There was a normal pulmonary valve and tricuspid annulus.

Review
OBJECTIVES
There has been a recent increase in our understanding of mechanisms whereby the two sides of the heart interact and modulate each other that may be particularly relevant to patients in the ICU. For this review, our objectives are to examine the function of the left ventricle, consider some of the ways in which the function of the right ventricle differs from that of the left, and examine the effects of the left ventricle on the function of the right and vice versa.
DATA SOURCE
MEDLINE and PubMed.
CONCLUSIONS
There are fundamental differences between the function of the left and right ventricles, which relate to a significant extent to differences in their respective arterial loads. Although traditionally it has been usual to consider the function of the left and right ventricle in isolation, it is now recognized that this approach is flawed and as a result there is an increasing appreciation of the continual cross talk between the two sides of the heart in both the normal and diseased states. A more rational approach to the use of standard therapies frequently used in the cardiac ICU will come from a better understanding of these important fundamental concepts, and novel therapeutic concepts are already emerging from new data regarding biventricular interactions.

Review
Survivorship into adulthood of patients with congenital heart disease is due to improvements in prenatal detection, novel surgeries, and specialized adult congenital heart disease care. As patients survive further into adulthood, long-term complications of congenital and repaired physiology have been more clearly elucidated. The overall mortality of patients with adult congenital heart disease with heart failure is around 4%. Congenital malformations, palliations, residual defects, and resultant physiology impact the right ventricle. This relationship influences morbidity and mortality. For this discussion, focus on atrial septal defects, Ebstein anomaly, Tetralogy of Fallot, transposition of the great vessels, and single right ventricle physiology.

Review
Percutaneous mechanical circulatory support options include intra-aortic balloon pump, transvalvular axial flow pumps, left atrial to femoral artery pumping, and oxygenated right atrium to femoral artery circuits. Percutaneous mechanical circulatory support devices providing greater support have not proven superiority over the intra-aortic balloon pump. Novel counterpulsation devices target durability and ambulatory capability and direct unloading of left ventricle (LV) and right ventricle. Device innovations in transvalvular axial pumping include miniaturization of partial-support devices and development of larger self-expanding devices for near-complete LV support. Aortic entrainment pumping is a novel mode of blood displacement with potential benefits beyond reduced LV afterload.

OBJECTIVES
Double-outlet right ventricle is a form of ventriculoarterial connection. The definition formulated by the International Society for Nomenclature of Paediatric and Congenital Heart Disease is based on hearts with both arterial trunks supported in their greater part by a morphologically right ventricle. Bilateral infundibula and ventricular septal defects are highly debated criteria. This study examines the anatomic controversies surrounding double-outlet right ventricle. We show that hearts with double-outlet right ventricle can have atrioventricular-to-arterial valvular continuity. We emphasize the difference between the interventricular communication and the zone of deficient ventricular septation.
METHODS
The hearts examined were from the University of Florida in Gainesville; Johns Hopkins All Children's Hospital, St Petersburg, Fla; and Lurie Children's Hospital, Chicago, Ill. Each specimen had at least 75% of both arterial roots supported by the morphologically right ventricle, with a total of 100 hearts examined. The morphologic method was used to assess anatomic features, including arterial-atrioventricular valvular continuity, subarterial infundibular musculature, and the location of the hole between the ventricles.
RESULTS
Most hearts had fibrous continuity between one of the arterial valves and an atrioventricular valve, with bilateral infundibula in 23%, and intact ventricular septum in 5%.
CONCLUSIONS
Bilateral infundibula are not a defining feature of double-outlet right ventricle, representing only 23% of the specimens in our sample. The interventricular communication can have a posteroinferior muscular rim or extend to become perimembranous (58%). Double-outlet right ventricle can exist with an intact ventricular septum.
