Coronary perforation is a rare but potentially lethal complication of percutaneous coronary intervention and it is associated with an increased risk of adverse outcomes. There are no standardized techniques to achieve prompt and effective perforation sealing and treatment is left to the operator's preference and expertise. We report a case of successful embolization of a distal coronary artery perforation using the "block and deliver" technique. The technique is relatively simple and safe, it was effective, and we are strongly convinced that it may be helpful to all interventional cardiologists in their daily practice.
