Abstract Few studies have evaluated the effects of pulmonary arterial hypertension therapies on pericardial effusion. We evaluated hemodynamics, echocardiograms, and outcomes for 119 parenteral prostanoid‐treated patients. We discovered an increased frequency of pericardial effusions posttreatment, and that a moderate‐large pericardial effusion at initiation, but not at 1st follow‐up, was significantly associated with mortality.

This case illustrates a novel percutaneous treatment of a highly vascular thoracic tumor impinging on the left atrium and right pulmonary artery by delivery of coils and alcohol ablation via a circumflex coronary artery feeder branch. (Level of Difficulty: Advanced.)
