Right ventricular hematoma: A rare but potentially fatal complication of percutaneous coronary artery intervention.

Right ventricular hematoma secondary to coronary artery perforation during the percutaneous coronary intervention (PCI) is a rare complication. Nevertheless, with the growth of complex PCIs, including chronic total occlusion procedures, this complication may increase in frequency. We describe three cases of subepicardial right ventricular hematoma after complex right coronary artery PCI with different outcomes. Two cases were successfully managed with medication only. One case was managed with medication and pericardial drainage, unfortunately with a fatal outcome. All cases emphasize the need for awareness concerning this complication, which warrants prompt diagnosis and adequate therapy.
