The article explores coronary blood flow in patients with Hypoplastic Left Heart Syndrome (HLHS) after Total Cavopulmonary Anastomosis (TCPC). The study found that while mean coronary blood flow in HLHS patients is slightly reduced compared to normal values, there is an increase in coronary blood flow during exercise for most patients. Additionally, the cross-sectional area of the native aorta showed a weak positive correlation with the increase in coronary blood flow during stress. This research sheds light on the long-term complications faced by HLHS patients surviving into early adulthood. [Extracted from the article]

This article discusses a multicenter study on Fontan patients, focusing on the prognostic value of cardiac magnetic resonance (CMR) imaging. The study included 502 Fontan patients from Germany and identified risk factors for adverse outcomes, such as dilated single ventricles and impaired systolic function. Elevated systemic-to-pulmonary collateral flow (SPC) was also found to be an independent risk factor for adverse events. The findings suggest the importance of further research into effective occlusion strategies for these collaterals. [Extracted from the article]
