percutaneous balloon pericardiotomy and window creation for treating recurrent massive pericardial effusion in patients with cancer: a case series and literature review

Cancer is the second leading cause of death worldwide, and pericardial effusion is relatively common in these patients. what constitutes the best therapeutic method for treating pericardial effusion in patients with cancer is controversial. recent decades have witnessed the introduction of percutaneous balloon pericardiotomy, an effective and less-invasive method with lower recurrence rates than pericardiocentesis for draining pericardial effusion in patients with cancer who have a poor prognosis.we herein describe 2 patients with a history of metastatic melanoma and metastatic breast cancer, presenting with symptomatic massive pericardial effusions. the patients had experienced 2 episodes of cardiac tamponade in the preceding 4 to 5 months, treated via surgical drainage. in their current episode, they were both successfully treated via percutaneous balloon pericardiotomy, and there was no recurrence of significant pericardial effusion reported during the follow-up.
