Surgical correction of ALCAPA is highly recommended, regardless of age or the degree of intercoronary collateralization. This protocol presents a technique for the direct re-implantation of adult-type ALCAPA into the aorta to re-establish the dual-coronary perfusion. Whenever feasible, direct re-implantation is preferred to other surgical correction techniques.

The following protocol describes the methodology for the acquisition and analysis of echocardiographic images used to obtain the Left Atrial Volume (LAV), Aorta (Ao) diameter, and Pulmonary Artery (PA) diameter in mice. This technique is a non-invasive, non-terminal procedure that allows assessment of the cardiopulmonary function.

We describe a method for creating a reliable model of cerebral venous hypertension in the adult mouse. This model has been widely described and tested in the rat. This new counterpart in the mice opens the possibility of using genetic modified animals and thereby broadens the applications of the model.

The protocol provides a detailed introduction to the experience of using the right heart catheterization method to detect pulmonary artery pressure in rats, which will help to obtain accurate data more efficiently and improve the success rate of the experiment. This method also improves the reproducibility of experiments across different laboratories.
FAQs
Accurate alignment helps preserve a continuous, unobstructed channel for blood flow. Maintaining the vessel’s lumen diameter limits narrowing at the connection, while controlled suturing supports the joined segments without placing excessive tension on the repair. These factors directly influence pulmonary perfusion and help the reconstructed pathway function efficiently within the pulmonary vascular system.
Excessive tension can compromise the integrity and geometry of the connection between pulmonary artery segments or between an artery and a graft. By joining the ends without undue stretch, surgeons support a stable pathway and reduce the likelihood that the repair will restrict flow. Preserving this continuity is important for delivering blood to the lungs.
Joining native pulmonary artery segments reconnects the patient’s existing vessel pathway, whereas a vascular graft supplies an additional conduit when direct reconnection is not suitable or when reconstruction requires replacement. In either approach, the connection must preserve lumen size and continuous flow. The selected configuration depends on the vascular defect and the surgical reconstruction.
A successful connection restores or improves the route by which blood reaches the lungs. Better pulmonary perfusion increases access to the pulmonary vascular system, where blood participates in oxygen exchange. The benefit therefore extends beyond the repaired vessel itself: reducing obstruction can help maintain circulation between the heart and lungs and support more effective respiratory gas exchange.
The essential priorities are to bring the vessel ends or graft into proper alignment, maintain the intended lumen diameter, and secure the junction with sutures while limiting tension. These steps create a continuous vascular pathway rather than a sharply narrowed or distorted connection. The procedure’s success is assessed by whether pulmonary blood flow can proceed through the reconstructed segment.
This reconstruction may be selected when congenital abnormalities disrupt the pulmonary artery pathway, or when damage or narrowing compromises the vessel. Reconnecting or rebuilding the affected segment can restore passage for blood from the heart to the lungs. Its purpose is to improve pulmonary perfusion and reduce obstruction within the pulmonary vascular circulation.
In pulmonary artery transplantation and other complex cardiothoracic procedures, the technique provides a means of connecting required vascular segments so circulation can continue through the operative reconstruction. Its value lies in integrating the artery or graft into the pulmonary vascular pathway while preserving lumen continuity. This supports blood delivery to the lungs after major surgical modification.
Effective function is reflected by a continuous pathway that permits blood to move through the reconstructed pulmonary artery without a significant obstructive effect. Preserved lumen diameter and appropriate vessel alignment support pulmonary perfusion, while reduced obstruction helps maintain circulation toward the lungs. These outcomes are biologically important because pulmonary blood flow contributes to efficient oxygen exchange.
