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.

As technology develops and becomes more user-friendly, planning of operations and patient-specific surgical guides and fixation plates should be performed by the surgeon. We present a protocol for 3D planning of orthognathic skeletal movements and 3D planning and printing of patient-specific fixation plates and surgical guides.
FAQs
Computer-aided design allows an implant model to incorporate the dimensions of a coronary vessel. Adjusting the digital geometry can help researchers examine how shape and fit relate to the intended device function. This design stage also provides a controlled basis for producing and comparing different implant configurations during laboratory development.
Selected biomaterials influence several properties of the finished device, including flexibility, strength, geometry, and potential interaction with surrounding tissue. Because these characteristics can affect how an implant performs and how it may be received biologically, material selection is a central research variable. Comparing materials helps investigators evaluate designs for both mechanical behavior and biocompatibility.
The pattern used to deposit material can be adjusted to control the implant’s geometry and structural behavior. These design changes may alter the balance between flexibility and strength, while also affecting potential tissue interaction. Studying different patterns therefore helps researchers identify configurations that support the intended coronary application and provide measurable differences in laboratory testing.
Development begins with a computer-aided design that can reflect vessel dimensions. Researchers then deposit selected biomaterials in precise patterns to create the planned geometry and structural characteristics. The resulting device can be examined through laboratory testing for performance and biocompatibility, allowing design and material choices to be assessed before considering broader cardiovascular applications.
Laboratory testing can provide information about device performance and biocompatibility. Performance assessment addresses whether the implant exhibits the intended structural or functional characteristics, while biocompatibility studies examine potential tissue interaction. Together, these evaluations help researchers compare designs, materials, and deposition patterns and determine which combinations merit further investigation in cardiovascular device research.
Their principal research value lies in exploring more individualized coronary devices, including patient-specific stents and vascular scaffolds. Designs can incorporate vessel dimensions, supporting investigation of how device geometry relates to a particular vascular context. In medicine, this approach is relevant to strategies for supporting, restoring, or improving blood flow in narrowed or damaged coronary vessels.
