Background: Patients with hypoplastic left ventricles (LV) who undergo volume-loading procedures (recruitment, biventricular [BIV] repair) are at risk for adverse outcomes, including heart failure and death. We investigated pre-BIV LV shape as a predictor of outcome after BIV repair in patients with hypoplastic LVs.
Methods: Baseline and post-recruitment cardiac magnetic resonance imaging and computed tomography data were analyzed in patients with hypoplastic LV (<50 mL/m).
Article Synopsis
- Postoperative atrioventricular block requiring pacemaker (AVB/PM) affects 14% to 25% of patients undergoing complex biventricular repair for congenital heart disease, especially those with heterotaxy syndrome.
- This study explored the safety and effectiveness of intraoperative His bundle (HB) mapping to reduce the incidence of AVB/PM during these procedures.
- Results showed that mapping significantly lowered AVB/PM rates in certain groups, while also highlighting the need for ongoing advancements in mapping technology for those still at risk.
Article Synopsis
- The Fontan operation is a procedure for patients with a single ventricle heart condition, historically improved to enhance patient outcomes and minimize complications, but concerns exist regarding the proper sizing of extracardiac conduits.
- A study aimed to evaluate the effects of upsizing these conduits using advanced imaging and fluid dynamics to find optimal sizes for improving blood flow and reducing complications.
- Results showed that upsizing conduits led to significant reductions in power loss (16%-63%), pressure gradients (15%-35%), and variations in local flow dynamics, emphasizing the necessity of personalized treatment strategies for better hemodynamic outcomes.
Background: Rates of reintervention (RI) after patch-augmented reconstruction for hypoplastic aortic arch (HAA) remain moderately high. We analyzed mid-term outcomes of aortic arch reconstruction to define modifiable reintervention risk factors.
Methods: Excluding Damus-Kaye-Stansel anastomoses and previous arch repair, 338 patients underwent arch reconstruction between 2000 and 2021 at median age of 6 days (interquartile range [IQR], 4-13 days) and a median weight of 3.
Background: Late hypertension (HTN) after coarctation of the aorta (CoA) repair contributes to higher morbidity and mortality. An association between transverse aortic arch (TAA) hypoplasia and HTN has been found, but its relationship with surgical strategy is unclear. We studied the association between late HTN and initial surgical strategy pertaining to the TAA.
