Abstract Aims We aim to determine any additional benefit of virtual reality (VR) experience if compared to conventional cross-sectional imaging and standard 3D modelling when deciding on surgical strategy in patients with complex double outlet right ventricle (DORV). Methods and results We retrospectively selected ten consecutive patients with DORV and complex interventricular communications, who underwent biventricular repair. An arterial switch operation (ASO) was part of the repair in three of those. CT or cardiac MRI images were used to reconstruct patient-specific 3D anatomies, which were then presented using different visualisation modalities: 3D pdf, 3D printed models, and VR models. Two experienced paediatric cardiac surgeons, blinded to repair performed, reviewed each case evaluating the suitability of repair following assessment of each visualization modalities. In addition, they had to identify those who had ASO as part of the procedure. Answers of the two surgeons were compared to the actual operations performed. There was no mortality during the follow-up (mean = 2.5 years). Two patients required reoperations. After review of CT/CMR images, the evaluators identified the surgical strategy in accordance with the actual surgical plan in 75% of the cases. When using 3D pdf this reached only 70%. Accordance improved to 85% after revision of 3D printed models and to 95% after VR. Use of 3D printed models and VR facilitated the identification of patients who required ASO. Conclusion VR can enhance understanding of suitability for biventricular repair in patients with complex DORV if compared to cross-sectional images and other 3D modelling techniques.

Objective: To discuss the key anatomic features of double outlet right ventricle (DORV) assessed by preoperative echocardiography among patients treated with different types of biventricular repair. Methods: Surgical and echocardiographic databases were queried to identify patients who had undergone biventricular repair for DORV and had adequate preoperative echocardiographic imaging. All patients underwent pre- and postoperative echocardiography and clinical evaluation following discharge. Results: Two hundred sixty-two patients with DORV met the inclusion criteria of the study. The patients were divided into two groups—intraventricular tunnel repair (IVR) to the aorta (194 [74%] patients) or to the pulmonary artery with either concomitant arterial switch operation or double-root translocation (68 [26%] patients). Among 68 patients undergoing IVR to the pulmonary artery, 50 patients with transposition of the great arteries (TGA) type of DORV and 7 patients with remote ventricular septal defect (VSD) type underwent IVR plus arterial switch operation and 6 patients with TGA type and 5 patients with remote VSD type underwent IVR plus double-root translocation. There were three hospital deaths and one late death (overall operative mortality: 1.5%). Conclusion: Preoperative echocardiography provided crucial data to estimate the feasibility of intraventricular tunnel creation to either the aorta or the pulmonary artery and to guide the selection of either arterial switch or double-root translocation. Biventricular repair could be achieved with favorable outcomes in most patients with DORV.

AbstractA ventricular septal defect is, almost always, an integral part of double outlet right ventricle and has been classified into the subaortic, subpulmonary, doubly committed and non-committed varieties. This study was performed to correlate the cross-sectional imaging characteristics of such ventricular septal defect in double outlet right ventricles using pathological specimens. The extent and the orientation of the outlet septum were the most important in the differentiation of the four varieties of ventricular septal defect. In the subaortic variety, the outlet septum fused with the left anterior margin of the defect, this being marked by the anterior limb of the septomarginal trabeculation. In the subpulmonary variety, the outlet septum fused with the right posterior margin of the defect, this being the posterior limb of the septomarginal trabeculation. The outlet septum was vestigial in case with doubly committed defects. In those with non-committed defects, the defect was not shown in those images or sections which demonstrated the outlet septum.

The authors achieved biventricular repair in a 1-year-old boy having double outlet right ventricle and unusual straddling of the mitral valve. There was a substantial abnormal muscular bar present within the right ventricle, and some of the tendinous cords of the mitral valve were attached to this structure. Preoperative echocardiography was particularly informative in enabling the surgeon to arrange the optional operative procedures. The postoperative course was smooth and uneventful.
