The LeCompte maneuver is a technique used in open heart surgery, primarily on infants and children.The maneuver entails cutting the main pulmonary artery and moving it anterior to the aorta before reattaching the pulmonary artery during the following reconstruction of the great vessels.
The incidence of univentricular heart malformations is estimated at 0.1 to 0.4 per 1,000 live births. [3] In the neonatal period, these patients depend on an aortopulmonary shunt that is maintained medically with prostaglandin and then surgically with an initial cardiac shunt procedure.
Diagram of the human heart. Several adaptations of the Ross procedure have evolved, but the principle is essentially the same; to replace a diseased aortic valve with the person's own pulmonary valve (autograft), and replace the person's own pulmonary valve with a pulmonary valve from a cadaver (homograft) or a stentless xenograft.
A pulmonary consolidation is a region of normally compressible lung tissue that has filled with liquid instead of air. [1] The condition is marked by induration [2] (swelling or hardening of normally soft tissue) of a normally aerated lung. It is considered a radiologic sign.
Since the pulmonary resistance is proportional to the pressure driving the pulmonary flow (=), it follows that the pulmonary pressure decreases. This in turn means that the work per time (power) decreases because it is equal to the pressure gradient times the volumetric flow , which in this case is the cardiac output.
Cardiac surgery, or cardiovascular surgery, is a surgery on the heart or great vessels performed by cardiac surgeons.It is often used to treat complications of ischemic heart disease (for example, with coronary artery bypass grafting); to correct congenital heart disease; or to treat valvular heart disease from various causes, including endocarditis, rheumatic heart disease, [1] and ...
Diagram of a pulmonary artery catheter in position. The pulmonary wedge pressure (PWP) (also called pulmonary arterial wedge pressure (PAWP), pulmonary capillary wedge pressure (PCWP), pulmonary artery occlusion pressure (PAOP), or cross-sectional pressure) is the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch.

A hybrid cardiac surgical procedure in a narrow sense is defined as a procedure that combines a conventional, more invasive surgical part (including a skin incision) with an interventional part, using some sort of catheter-based procedure guided by fluoroscopy (or other, e.g., CT or MRI) imaging in a hybrid operating room (OR) without interruption.
