A 79-year-old female patient was admitted to the hospital due to intense chest pain. Emergency percutaneous coronary intervention (PCI) revealed an occlusion in the distal portion of the left circumflex artery (LCx). The patient suffered from cardiac rupture, an uncommon yet extremely perilous condition, within 30 minutes following the procedure. This was verified through a computed tomography angiography (CTA) scan and bedside echocardiography. The etiology of cardiac rupture remains elusive, yet potential factors such as the patient's age, gender, initial acute myocardial infarction (AMI), and single-vessel disease without collateral circulation may be linked to this occurrence. This case report emphasizes that occluded tiny distal coronary arteries can also induce cardiac rupture and that a sufficient level of suspicion for the diagnosis of cardiac rupture should be raised when adequate fluid resuscitation fails to alleviate hypotension. Additionally, contrast-enhanced spiral computed tomography (CESCT) is highly effective in revealing certain pathological features associated with cardiac rupture.
