Iatrogenic coronary artery dissections (ICAD) are rare but potentially devastating complications during coronary angiography and percutaneous coronary interventions (PCI). Intima media complex separation may be produced either by the catheter tip or during PCI. Patient characteristics and procedure related risk factors are intimately linked to catheter induced ICAD over diagnostic angiography. Moreover, the increasing complexity of patients undergoing PCI, which frequently involves treatment of heavily calcified or occluded vessels, has increased the likelihood of dissections during PCI. A prompt recognition, along with a prompt management (either percutaneous, surgical or even careful watching), are key in preventing catastrophic consequences of ICAD, such as left ventricular dysfunction, cardiogenic shock, periprocedural myocardial infarction (MI) or cardiac death. This review aims to summarize the main updates concerning the pathophysiology, highlight key risk factors and suggest recommendations in management and treatment of ICAD.
