Malignant cardiac tamponade: safety and efficacy of intrapericardial bleomycin instillation

Background Malignant cardiac tamponade is a life-threatening condition that requires prompt treatment and effective management to prevent recurrence. This paper describes safety and efficacy outcomes after intrapericardial instillation of bleomycin as well as possible predictors of survival. Methods We performed a 10-year retrospective, single-center study to evaluate the safety and efficacy of intrapericardial instillation of bleomycin in patients with suspected malignant cardiac tamponade. Results Intrapericardial instillation of bleomycin was performed in 31 cancer patients (9 men, 22 women) presenting with cardiac tamponade. Non-fatal complications occurred in 3 patients and relapse occurred in 1 patient. Overall survival was less than 10% at the end of the study. Median survival was 104 days (95% CI, 0-251 days). Survival was compared between different groups (defined by primary tumor, type of tumor, TNM stage and results of cytological analysis) with median survival being considerably higher when oncologic therapy was altered afterwards. Conclusions The use of intrapericardial bleomycin instillation following pericardiocentesis for malignant cardiac tamponade is a safe procedure with a high success rate. Survival rates depend on further oncological treatment options available.
