We describe complex atrial baffling procedures in the setting of left isomerism with right-hand as opposed to left-handed ventricular topology. An appropriate understanding of the connections of the systemic and pulmonary veins, along with the internal atrial anatomy, as revealed using 3D printing, allowed for successful biventricular repair.

Background: Pulmonary autograft failure remains a cause of reoperation following the Ross procedure. The aim of this study is to describe our evolving approach to autograft reoperations. Methods: Retrospective study of all patients who underwent a pulmonary autograft reoperation following a Ross procedure between June 1997 and July 2022. Results: Two-hundred and thirty-five Ross procedures were performed. Thirty-six patients (15%) plus one referral underwent an autograft reoperation at a median of 7.8 years (IQR 4...

This study aimed to compare the clinical characteristics and courses of pediatric patients with cardiac tumors in nonoperative and operative groups to help guide treatment decisions. We reviewed the medical records of patients diagnosed with primary pediatric cardiac tumors at our institution between 2003 and 2020. Demographic data, clinical characteristics, and follow-up data between the operation and nonoperation groups were compared. A total of 56 patients were included in the study. Thirteen patients underwent surgery...

BACKGROUND: Nearly 1% or 1.3 million babies are born with congenital heart disease (CHD) globally each year - many of whom will require palliative or corrective heart surgery within the first few years of life. A detailed understanding of cardiac maturation can help to expand our knowledge on cardiac diseases that develop during gestation, identify age-appropriate cardiovascular drug therapies, and inform clinical care decisions related to surgical repair, myocardial preservation, or postoperative management...

Anatomic and physiologic assessment of surgical repair of scimitar syndrome can be challenging. We evaluated the first patient who underwent the Lugones procedure in 2012 using 4D flow magnetic resonance imaging. With this technology, we demonstrate that the reconstructed right pulmonary venous return drains into the left atrium with laminar flow, just as normal pulmonary veins do.

IMPORTANCE: Hypertension affects 6% of all children, and its prevalence is increasing. Childhood hypertension tracks into adulthood and is associated with subclinical cardiovascular disease; however, there is a lack of evidence linking childhood hypertension to cardiovascular outcomes, which may contribute to underdiagnosis and undertreatment. OBJECTIVE: To determine the long-term associated risk of major adverse cardiac events (MACE) among children diagnosed with hypertension...

Chylothorax in infants after surgery for congenital heart disease is associated with significant morbidity and mortality. Numerous management modalities applied alone or in various combinations have been utilized but definitive guidelines have not yet been established. We present two infants who developed refractory chylothorax after congenital heart surgery. We also reviewed evidence for the use of available treatment modalities. In our experience, the use of lymphangiography followed by pleurodesis by povidone-iodine was safe and our impression was that it may have played a decisive role in controlling the lymph leak...

A nine-year old boy presented following a chest x-ray for COVID-19 infection that showed cardiomegaly. Transthoracic echocardiogram revealed a large atrial septal defect, dilated right heart, and normal function. Surgical repair was performed eight weeks after his COVID diagnosis. After weaning from cardiopulmonary bypass, pulmonary artery pressures were 2/3 systemic and ectopy was seen, requiring inotropes, nitric oxide, lidocaine, and amiodarone. He was discharged on postoperative day (POD) 5. On POD 6, he presented with acute right foot ischemia...

Advancements in early diagnosis and paediatric cardiac surgery have improved the long-term survival of patients with congenital heart disease, necessitating a thorough assessment of their health-related quality of life (HRQoL). This study aimed to assess HRQoL in paediatric patients with coarctation of the aorta (CoA) (both as reported by patients and caregivers), and to evaluate associated factors. Patients aged 5-18 years diagnosed with CoA and their parents were enrolled at Bambino Gesù Children's Hospital between September 2016 and December 2017...

PURPOSE: Infection prevention and control (IPC) has a significant impact on the prognosis after pediatric cardiac surgery. This study aimed to provide surveillance data on the incidence and density of various infections during the COVID-19 epidemic and explore the influence of multi-drug resistant organisms (MDRO) on in-hospital prognosis after congenital heart disease surgery. METHODS: This single-center retrospective study included pediatric patients who underwent cardiac surgery between 2021 and 2022...

BACKGROUND: Sternal infection is one of the most challenging complications to manage after heart surgery. The aim of our study is to evaluate the effectiveness of a developed algorithm for preventing sternal infection in pediatric patients after surgery for congenital heart disease (CHD). METHODS: We conducted a single-center study examining the treatment of 478 children with CHD. Patients were divided into 2 groups, taking into account the application of a developed management algorithm...

Ebstein anomaly is a myopathy of the right ventricle characterized by failure of tricuspid valve delamination with accompanying tricuspid regurgitation. Its rarity, considerable anatomic variability, and frequent absence of symptoms can make the timing of surgery challenging. Contemporary tricuspid repair techniques can be performed with low mortality and bidirectional cavopulmonary anastomosis reduces the risk of operation when right ventricular function is poor. Here, we present a patient who presented late for surgery, failed high-risk conventional surgery and required heart transplantation...

Anomalous left coronary artery from the pulmonary artery (ALCAPA) is an uncommon life-threatening congenital heart defect that occurs mostly as an isolated lesion. It is very rarely associated with other cardiac abnormalities. In this report, we present a case of an infant who successfully underwent complete surgical repair of a rare triad of congenital heart defects, including ALCAPA, ventricular septal defect (VSD), and double aortic arch (DAA). To the best of our knowledge, this is only the second case of ALCAPA diagnosis associated with VSD and DAA that has been described in the literature...

Uhl's anomaly is a rare congenital syndrome characterized by the absence of right ventricular myocardium. The widely accepted pathological mechanism is intrauterine myocardial apoptosis. Uhl's syndrome carries a poor prognosis. In rare situations, patients with Uhl's anomaly reach adulthood. We will present a case of a 29-year-old patient with Uhl's syndrome treated at our center, highlighting the diagnostic, surgical, and postoperative challenges in management.
