A Case of Coronary Artery Perforation Caused by Manual Cardiopulmonary Resuscitation in the Catheterization Laboratory.

Cardiopulmonary resuscitation (CPR) is essential for the survival of cardiac arrest patients, but it can cause severe traumatic complications. In the catheterization laboratory, various physical constraints complicate the appropriate performance of CPR. However, we are not aware of reports of CPR complications in this setting. Here, we report a case of coronary artery perforation (CAP) caused by manual CPR in the catheterization laboratory. The patient, a 68-year-old woman, initially underwent successful percutaneous coronary intervention (PCI) for unstable angina. Back in the ward, the patient experienced acute stent thrombosis, which resulted in cardiac arrest, and another PCI was performed under ongoing manual CPR. Although revascularization was successful, sudden CAP occurred, leading to cardiac tamponade. Despite extensive treatment efforts, the patient died 18 hours later.Initially, the compression site of CPR was on the midline of the sternum; however, the compression site shifted to the left, to just above the left anterior descending artery, by the time that CAP was detected via angiography. This corresponded to the area where rib fractures were observed upon computed tomography, suggesting the possibility of traumatic CAP due to manual CPR. The physical constraints in the catheterization laboratory can lead to an inappropriate CPR technique and severe traumatic complications.
