It is also used off-label to treat pericarditis, calcium pyrophosphate illness, and Behçet's syndrome. There are additional studies on the use of colchicine, which is accepted as the standard treatment for pericarditis in adults, post-pericardiotomy syndrome, post-operative and post-ablation atrial fibrillation, coronary artery disorders, prior to percutaneous coronary procedures, and myocarditis.

Subcutaneous use of treprostinil in pediatric pulmonary hypertension patients: A report of three cases.

Treprostinil was approved by the United States Food and Drug Administration for use in the treatment of pulmonary arterial hypertension in 2002. Intravenous or subcutaneous treprostinil is used in pulmonary arterial hypertension patients in the functional classes of II-IV to alleviate exercise-related symptoms, or in cases where epoprostenol treatment should be reduced due to side effects. In this article, we describe three pediatric cases of pulmonary arterial hypertension in whom subcutaneous treprostinil was used.

Coexistence of transposition of the great arteries, coarctation of the aorta, and bilateral pulmonary artery hypoplasia.

Transposition of the great arteries is the most common cyanotic CHD in newborns. This CHD, in which the aorta arises from the right ventricle and the pulmonary artery from the left ventricle, is often accompanied by one or several defects such as atrial septal defect or patent foramen ovale, ventricular septal defect and patent ductus arteriosus, which allow the transition between both parallel circulations. Rarely, the disease may be accompanied by left ventricular outflow tract obstruction (subpulmonary obstruction) and coarctation of the aorta.
