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 demonstration begins with a brief overview of the anatomy of the region. The upper third of the nose is bony, and the bottom two-thirds are cartilaginous. Air entering the nares passes through the nasal vestibules and into the narrow passageway between the nasal septum...
FAQs
Electrodes positioned within the coronary sinus record electrical signals from a defined cardiac location. These recordings add information about cardiac electrical activity to an electrophysiology study and can support cardiac mapping. By comparing signals from this venous position with other cardiac measurements, clinicians can better characterize rhythm disorders and guide diagnostic or treatment decisions.
Depending on its configuration, the catheter can support electrical recording, pressure monitoring, or blood collection from the coronary sinus. Electrodes are used for signal acquisition, while ports can provide access for pressure assessment or sampling. This flexibility allows clinicians to examine cardiac function through several measurement types during an appropriate cardiac evaluation.
The coronary sinus provides access to the venous circulation associated with the heart muscle. Positioning electrodes or ports there allows measurements or samples to come from a defined cardiac location rather than from the general venous system. This targeted access can improve the relevance of information used for cardiac mapping, rhythm assessment, or hemodynamic evaluation.
Clinicians advance the thin, flexible catheter through the venous system while using imaging to guide its path. They then place its electrodes or ports within the coronary sinus so the intended recordings, pressure measurements, or blood samples can be obtained. Imaging-guided positioning connects the physical catheter location with the cardiac data being collected.
In electrophysiology studies, the catheter can provide electrical signals from the coronary sinus while clinicians evaluate cardiac rhythm. Its recordings contribute to cardiac mapping, which helps characterize the location or pattern of electrical activity relevant to rhythm disorders. The resulting information may support diagnosis and help guide treatment planning.
Access through the coronary sinus can support pressure monitoring and blood sampling from a defined cardiac venous location. These measurements contribute to hemodynamic assessment, meaning evaluation of pressure-related cardiac function, and the catheter may also be used in selected procedures requiring targeted access to cardiac veins. Its value depends on the clinical objective and required measurement.
