This retrospective multicenter study examined late surgical outcomes for children from low and middle income countries with double outlet right ventricle (DORV). DORV was defined as both great arteries arising entirely or mostly from the right ventricle. A total of 81 consecutive DORV repairs were performed between 1996 and 2022. Six subtypes of DORV were divided into two overall groups: (i) DORV-committed ventricular septal defect (VSD) and (ii) DORV-noncommitted (nc) VSD. Four Fontan patients were excluded, and three patients were lost to follow up. Overall perioperative mortality was 7.4 percent. Overall, 1--year survival was 86 percent. Early mortality was similar in both groups. There was a trend toward satisfactory outcome of biventricular repair for simple DORV with committed VSD compared with complex DORV with ncVSD.

In this study, the authors aimed to analyze the one-year outcome after aortic valve (AV) repair versus surgical AV replacement (SAVR) in patients with aortic regurgitation (AR) using data from the German Aortic Valve Registry (GARY). A total of 8,076 AR patients were included in the analysis. The AV was repaired in 2,327 patients (29 percent) and 5,749 patients (71 percent) underwent SAVR. Patients were matched to correct for baseline differences in both study groups. After adjusting for baseline differences, the one-year survival rate was 97.7 percent (95 percent CI, 97.0 percent to 98.5 percent) in the AV repair cohort versus 96.4 percent (95 percent CI, 95.9 percent to 96.9 percent) SAVR cohort (log-rank P < 0.001). Cox regression analysis showed a significant age independent advantage of AV repair compared with SAVR (hazard ratio, 0.68; 95 percent CI, 0.51-0.90; P < 0.0001) on one-year survival. Furthermore, cardiac event-free survival at one year was 85.7 percent (95 percent CI, 483.8 percent to 87.7 percent) in the AV repair group versus 81.7 percent (95 percent CI, 80.7 percent to 82.9 percent) in the SAVR group (log-rank P < 0.001). There was no difference in the need for AV reintervention when comparing both the AV repair and SAVR cohorts (P = 0.59). The authors concluded that AV repair surgery, if technically feasible, is associated with higher superior one-year survival and one-year cardiac event-free survival than SAVR.

This annual report from The Society of Thoracic Surgeons Adult Cardiac Surgery Database summarizes key research; trends in patient characteristics; surgeon case volume; surgical techniques including minimally invasive and robotic approaches, repair and replacement, prosthesis, and conduit choice; and concomitant atrial fibrillation surgery in isolated coronary bypass, aortic, mitral, and tricuspid valve surgery between 2015 and 2022.

This study addressed midterm outcomes with the hemispherical aortic annuloplasty reconstructive technology (HAART) ring used for aortic valve repair (AVr). Seventy-one patients had AVr using the HAART ring—53 had a trileaflet valve and 18 had a bicuspid valve. Their median age was 54 years old and 79 percent were male. Many patients needed concomitant interventions such as arch repair (77 percent) or a root procedure (46 percent). At a mean follow up time of 3.9 ± 1.1 years, freedom from reoperation was 96 percent. Eleven patients had moderate or higher aortic insufficiency (AI) during surveillance, and all of these patients had a trileaflet valve. Three patients suffered ring dehiscence. The authors recommend caution when using the subannular approach for stabilization in patients with trileaflet aortic valves.
