摘要

Background Acquired coronary cameral fistula is an extremely rare condition that involves an abnormal communication between a coronary artery and a cardiac chamber. It usually occurs after chest trauma or cardiovascular interventions, such as percutaneous coronary intervention (PCI) and is associated with various outcomes, ranging from a stable status to haemodynamic instability. Acquired coronary cameral fistula frequently arises from the right coronary artery and drains generally into the right ventricle. Case summary We report the unusual case of a 56-year-old male patient referred to an invasive cardiology centre for a suspected left anterior descending (LAD) coronary–left ventricular (LV) fistula resulting from a primary PCI for an anterior ST-elevation myocardial infarction. Here, the confirmed LAD–LV fistula was successfully treated by retrograde PCI with covered stent implantation. Clinical and angiographic outcomes were favourable at 1-month follow-up. Discussion Coronary cameral fistula can be a severe complication of primary PCI. Various treatment strategies can be considered based on haemodynamic status and anatomical features. In the case described herein, the use of a retrograde approach led to permanent fistula closure and complete revascularization.
