A 44-year-old female patient was admitted to our clinic with exertional angina. She has a family history of premature coronary artery disease as a conventional cardiac risk factor. Electrocardiogram revealed normal sinus rhythm. Since stress electrocardiogram was equivocal for ischemia, coronary angiography was scheduled. During coronary angiography, the diagnostic coronary catheter spontaneously engaged deeply into the small caliper intermediate coronary artery after the first contrast injection to the left main coronary artery. Following contrast injection resulted in rupture of the intermediate artery secondary to injection pressure (Figures 1 A–D). Extravasation of the contrast material was limited to the myocardium and did not pass into the pericardial space. Control echocardiography showed no wall motion abnormality or pericardial effusion. No cardiac biomarker elevation was observed during follow-up ho­wever the patient described chest pain compatible with acute pericarditis secondary to coronary accident. This diagnosis was also supported by electrocardiography (Figures 2 and 3). Since the patient was stable, no further intervention was scheduled and she was discharged without any sequel after a 3-day hospitalization.

Coronary artery rupture is an exceedingly rare complication during diagnostic coronary angiography and reported cases are mostly secondary to percutaneous coronary interventions. Presence of a small-calibre intermediate co­ronary artery which is coaxial to the left main coronary artery may deserve additional care to avoid deep engagement which may result in potentially catastrophic coronary artery rupture. Depending on the location and severity of the rupture, covered stent implantation, coil embolisation and surgery may be a treatment option. As we observed in our patient, for self-limiting ruptures in haemodynamically stable cases, a conservative strategy may be promising.
