We present a 26-year-old woman who came to the emergency department with chest pain of 1 hour duration that started while she was exercising on the treadmill. At presentation, ECG showed sinus bradycardia. Initial troponin level was 0.05 ng/mL and her chest pain resolved within 3 hours of onset. Troponins were trended serially, which continued to rise and peaked at 28.77 ng/mL and so heparin drip was started. On the second day of admission, a coronary angiogram was performed along with intravascular ultrasound, which revealed type 3 spontaneous coronary artery dissection. No obstructive atherosclerotic disease was noted in any of the coronary vessels. No coronary intervention was performed. Patient was started on aspirin and clopidogrel. Patient was discharged home in stable condition and was followed outpatient, where she remained in excellent health condition at her first clinic visit., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2020.

Spontaneous coronary artery dissection (SCAD) is a rare cause of acute myocardial infarction, which should always be included in differential diagnoses of acute coronary syndrome among young patients without known atherosclerotic risk. Although, it is commonly observed in young women during postpartum period, there were cases reported in connective tissue disorders, eosinophilic arteritis, contraception use, cocaine abuse and repetitive chest trauma. We report a case of SCAD, presenting with acute ST-elevation myocardial infarction, which was successfully treated conservatively.

Anomalous right coronary artery from the pulmonary artery (ARCAPA) is a rare congenital coronary anomaly that has an incidence of 0.002%. We report a case of a previously healthy female who presented to our hospital with pneumonia and was incidentally discovered to have ARCAPA. This was initially diagnosed on echocardiography by the unusual echocardiographic finding of multiple color flow Doppler signals around the right ventricular free wall and apex which were subsequently confirmed by angiography to be due to extensive collateral circulation between the left and right coronary arteries. This represents an unusual echocardiographic manifestation of this very rare condition., (© 2013, Wiley Periodicals, Inc.)
