One hundred-five patients (median age 14 months) in whom a PTFE prosthesis was used to create a systemic-pulmonary artery shunt were studied between 1978 and 1980. The prosthesis was mainly used to create a modified Blalock-Taussig anastomosis. Nine patients died in hospital (8.5%, 70% confidence limits: 5.7% to 12.3%). The clinical condition did not appear to be an incremental risk factor, while the young age and the underlying type of disease accounted for the hospital mortality to a large extent. All 96 survivals were available for follow-up information. One graft, which was damaged intraoperatively, occluded 3 months later. The remaining patients have a patent graft 3 months to 36 months (mean 24 months) postoperatively. In 6 patients the patency was assessed angiographically and no damages of the pulmonary artery were observed, therefore this type of palliation is advisable for any patient, particularly in the first year of life.

: Truncus arteriosus communis (TAC) is a rare congenital heart defect characterized by a single arterial trunk that supplies systemic, pulmonary, and coronary circulations. This defect, constituting approximately 1-4% of congenital heart diseases, poses significant challenges in prenatal diagnosis, management, and postnatal outcomes. : A retrospective analysis was conducted at the local tertiary referral center on cases of TAC diagnosed prenatally between 2019 and 2024.

Article Synopsis
- A study examined the relationship between post-operative ECG changes, diastolic blood pressure (DBP), and negative outcomes in patients who underwent Systemic to Pulmonary Artery shunt surgery.
- Patients' ECGs were classified into three grades based on repolarization abnormalities, with only a small percentage showing Grade 2 abnormalities.
- The analysis revealed no link between ECG changes or low DBP levels and adverse outcomes; however, high DBP levels above 34 mmHg appeared to increase the risk of complications in certain patients.

Background: Pulmonary Atresia, Ventricular Deptal Defect, and Major Aortopulmonary Collateral Arteries (PA-VSD-MAPCAs) is a congenital cyanotic heart defect with poor prognosis. Due to its complex and highly variable anatomy, the best treatment plan is not clear. We aimed (1) to investigate the survival of PA-VSD-MAPCAs patients according to the underlying original anatomy and treatment strategy, and (2) to evaluate life expectancy between patients with or without severe hypoplastic native pulmonary arteries (NPAs) after surgical versus non-surgical treatment.

Article Synopsis
- A Loeys-Dietz syndrome patient underwent mitral valve repair and replacement of the aortic root and valve, revealing a previously misdiagnosed Morgagni hernia during a preoperative CT scan.
- The Morgagni hernia was found to contain omentum and was compressing the right ventricle, complicating the patient’s condition.
- Intraoperative observations revealed abnormal blood flow back into the left ventricle, later attributed to major aorto-pulmonary collateral arteries, highlighting the need to consider these congenital features in diagnosis and surgical treatment.
