Background:
A 28-year-old man presented at hospital with persistent pain in his chest and left arm, a paced rhythm on electrocardiography and elevated levels of cardiac enzymes. He was known to have patent foramen ovale and a dual-chamber pacemaker, which had been implanted following electrophysiological ablation to treat supraventricular tachycardia 3 years previously. The patient did not have a history of cardiovascular risk factors, recent travel, immobilization or clinical features of infection, and he was not taking any medication.
Investigations:
Electrocardiography, cardiac enzyme studies, coronary angiography and transthoracic echocardiography.
Diagnosis:
Acute myocardial infarction, paradoxical coronary embolus and patent foramen ovale.
Management:
Coronary aspiration embolectomy and systemic anticoagulation.
