Another cause of cardiac tamponade: ruptured coronary artery aneurysm

Background: Coronary artery aneurysm can be defined as an abnormal dilatation of the coronaries. In recent years, the disease has been frequently encountered during surgical procedures such as percutaneous coronary intervention (PCI) and coronary computed tomography angiography (CCTA). Case presentation: We reported a case of cardiac tamponade due to spontaneous rupture of coronary artery aneurysm in a 53-year-old Chinese man, who had collapsed and died at home after returning from work. Autopsy revealed a cardiac tamponade with ruptured aneurysm of the left circumflex artery. Conclusion: This case highlights the need to consider ruptured coronary aneurysm as a differential diagnosis when cardiac tamponade is encountered during autopsy. © 2018, The Author(s).
