Quality of life and exercise performance in unoperated children with anomalous aortic origin of a coronary artery from the opposite sinus of valsalva.

Background: Anomalous aortic origin of a coronary artery is a congenital cardiac condition that can be associated with increased risk of sudden death. To date, quality of life and exercise performance have not been evaluated in patients with this condition who do not undergo surgical repair.

Methods: We carried out a cross-sectional analysis of patients with unoperated anomalous aortic origin of a coronary artery at our institution from 1 January, 2000 to 31 January, 2016.

Pulmonary emboli associated with isolated lower-extremity venous malformation: a case report.

Pulmonary thromboembolism is a relatively rare entity in the pediatric population; however, it should always be part of the differential diagnosis in patients with the appropriate clinical presentation. We report the case of a 13-year-old girl with a history of a lower-extremity venous malformation status post sclerotherapy 2 years prior but otherwise healthy who presented with painless hemoptysis. She was found to have multiple bilateral pulmonary emboli on computed tomographic angiography of the chest.
