https://www.selleckchem.com/products/Mizoribine.html Congenital long QT syndrome (LQTS) is a rare cardiac condition characterized by abnormality of either sodium or potassium ion channels resulting in prolongation of QT interval and thereby predisposing to life-threatening arrhythmia. Once the syndrome is diagnosed, measures should be taken to avoid sudden cardiac death. We present a rare case of LQTS associated with patent ductus arteriosus in a child, and a unique approach was used in managing both conditions.Total anomalous pulmonary venous drainage (TAPVD) encompasses a wide spectrum of anatomical variants. The infradiaphragmatic type is almost always obstructive owing to the interposition of intrahepatic resistances; since almost invariable, the vertical vein inserts on the portal venous system. On correction of this variant, the vertical vein might not be ligated to avoid postoperative pulmonary hypertension. We hereby describe an unusual case of infradiaphragmatic TAPVD, with a vertical vein connected to ductus venosus. Since vertical vein was not ligated, it realized an unrestrictive pathway between the left atrium and the suprahepatic veins which resulted in persistent chylous peritoneal drainage. The patient successfully underwent catheter occlusion of the vertical vein which led to complete resolution of the clinical picture.Atrial flutter is uncommon in young patients with uncorrected atrial septal defect (ASD). Although rare, it has been reported in the younger population following device closure of ASD/patent foramen ovale. We describe a case of persistent atypical atrial flutter following device closure of ASD in a young man and discuss the management strategy given the various underlying dilemmas.Pulmonary arterial hypertension (PAH) is a chronic, progressive, multifactorial disease. Currently, combination therapy is an attractive option for PAH management because three pathways (endothelin, nitric oxide, and prostacyclin) are involved in this diseas
