Hybrid Palliation for Hypoplastic Borderline Left Ventricle: One More Chance to Biventricular Repair. CHILDREN (BASEL, SWITZERLAND) 2023; 10:children10050859.

Abstract
Treatment options for hypoplastic borderline left ventricle (LV) are critically dependent on the development of the LV itself and include different types of univentricular palliation or biventricular repair performed at birth. Since hybrid palliation allows deferring major surgery to 4-6 months, in borderline cases, the decision can be postponed until the LV has expressed its growth potential. We aimed to evaluate anatomic modifications of borderline LV after hybrid palliation. We retrospectively reviewed data from 45 consecutive patients with hypoplastic LV who underwent hybrid palliation at birth between 2011 and 2015. Sixteen patients (mean weight 3.15 Kg) exhibited borderline LV and were considered for potential LV growth. After 5 months, five patients underwent univentricular palliation (Group 1), eight biventricular repairs (Group 2) and three died before surgery. Echocardiograms of Groups 1 and 2 were reviewed, comparing LV structures at birth and after 5 months. Although, at birth, all LV measurements were far below the normal limits, after 5 months, LV mass in Group 2 was almost normal, while in Group 1, no growth was evident. However, aortic root diameter and long axis ratio were significantly higher in Group 2 already at birth. Hybrid palliation can be positively considered as a "bridge-to-decision" for borderline LV. Echocardiography plays a key role in monitoring the growth of borderline LV.

Abstract
UNLABELLED Aims The aim of this study was to describe atrial septal defect morphology in hypoplastic left heart syndrome, to report the incidence of restrictiveness and its relationship with defect morphology, to correlate restriction with midterm outcome, and to describe our interventional approach to restrictive defect. Methods and results From 2011 to 2015, 31 neonates with hypoplastic left heart syndrome underwent hybrid procedure with pulmonary artery banding and ductal stenting at our Institution. Restrictive physiology of the atrial septal defect was based on Doppler gradient >6 mmHg through the defect and on clinical signs of pulmonary hypertension. The mean gradient was then measured invasively. Restrictive defect occurred in 11/27 patients (40%). The restrictive group showed three ostium secundum defects (27%) and eight complex morphologies (73%). Conversely, in the non-restrictive group, we observed 11 ostium secundum defects (69%) and five complex morphologies (31%). Early balloon atrioseptostomy was required in three cases. Late restriction occurred in eight patients and was dealt with balloon dilation, stenting, or atrioseptectomy. There was no significant difference between restrictive and non-restrictive groups in terms of early or 12-month survival. CONCLUSIONS Complex morphologies were more frequently related to restrictiveness. Stenting technique has a crucial role, as the procedure carries a significant risk for stent migration. Effective treatment of restrictive atrial septal defect is related to a better outcome, as it leads to equalisation of survival between patients with and those without restrictive atrial septal defect.

Abstract
Within the last few decades the pre-natal echocardiographic diagnosis of congenital heart defects has made substantial progresses, particularly for the identification of complex malformation. "Functionally" univentricular hearts categorize a huge variety of heart malformations. Since no one of the patients with these congenital heart defects can ever undergo a bi-ventricular type of repair, early recognition and decision-making from the neonatal period are required in order to allow for appropriate multiple-step diagnostic and treatment procedures, either of interventional cardiology and/or surgery, on the pathway of "univentricular" heart. In the literature strong disagreements exist about the potential impact of the pre-natal diagnosis on the early and late outcomes of complex congenital heart defects. This review of the recent reports has been undertaken to better understand the impact of pre-natal diagnosis in "functionally" univentricular hearts taking into consideration the following topics: pre-natal screening, outcomes and survival, general morbidity, neurologic and developmental consequences, pregnancy management and delivery planning, resources utilization and costs/benefits issues, ethical implications, parents counseling, and interruption of pregnancy versus treatment.
