Apical Left Ventricle to Ascending Aorta Conduit

In small infants, when an apical-aortic conduit is required, there may be inadequate space in which to work to attach the conduit to the descending aorta when working through a median sternotomy. Here the conduit is attached to the ascending aorta.

Sternotomy

main pulmonary artery ascending aorta

Figure 14-74. Through a median sternotomy, a small ascending aorta is seen. The procedure is performed with cardiopulmonary bypass, moderate hypothermia, aortic clamping, and cardioplegic arrest plus profound local cooling.

Blood Pressure Health

Your heart pumps blood throughout your body using a network of tubing called arteries and capillaries which return the blood back to your heart via your veins. Blood pressure is the force of the blood pushing against the walls of your arteries as your heart beats.Learn more...
