Double Outlet Right Ventricle: In-Depth Anatomic Review Using Three-Dimensional Cardiac CT Data

Area of Science:

• Cardiology
• Medical Imaging
• Pediatric Surgery

Background:

• Double outlet right ventricle (DORV) is a common congenital heart defect where both great arteries connect to the right ventricle.
• DORV presents diverse subtypes, mimicking other complex heart conditions, necessitating precise preoperative assessment.
• Surgical strategies vary significantly based on DORV subtypes and associated ventricular septal defects.

Purpose of the Study:

• To review major anatomic factors influencing surgical decision-making in DORV with ventricular septal defects.
• To highlight the utility of cardiac CT in characterizing DORV morphology.
• To describe surgical procedures and postoperative complications associated with DORV.

Main Methods:

• Comprehensive review of major anatomic factors in DORV with ventricular septal defects.
• Utilized three-dimensional cardiac CT data for detailed intracardiac morphologic assessment.
• Described surgical procedures and major postoperative complications.

Main Results:

• Cardiac CT offers high spatial and contrast resolution for accurate DORV characterization.
• Detailed assessment of intracardiac anatomy is crucial for selecting appropriate surgical strategies.
• Understanding DORV subtypes is key to managing surgical interventions and potential complications.

Conclusions:

• Cardiac CT is invaluable for preoperative assessment of DORV, enabling tailored surgical planning.
• Accurate characterization of DORV subtypes and intracardiac anatomy improves surgical outcomes.
• This review provides a comprehensive overview for clinicians managing DORV patients.
