Combined spontaneous coronary artery dissection (SCAD) and Takotsubo syndrome (TTS): a case series

BackgroundSpontaneous Coronary Artery Dissection (SCAD) and Takotsubo Syndrome (TTS) are two different entities with several shared risk factors, but their management is different. They can co-exist in patients with chest pain which affects their management. We present two cases of combined SCAD and TTS in patients presented with chest pain.Case presentationCase 1: 80F admitted with typical chest pain and dynamic ECG changes on the background of known anxiety/depression and social stresses. Her coronary angiogram showed SCAD affecting distal LAD. The left ventriculogram (LV gram) showed apical ballooning consistent with Takotsubo Syndrome (TTS). Patient was discharged on aspirin as well as angiotensin receptor blocker (ARB).Case 2: 60F admitted with typical chest pain in the setting of emotional trauma on the background of known cardiovascular risk factors. She was found to have ST elevation in inferior leads with no reciprocal changes. Subsequently, coronary angiogram showed SCAD affecting mid-left anterior descending artery (LAD) with normal distal wrap around LAD. Her LV gram showed apical ballooning consistent with TTS. However, transthoracic echocardiogram showed akinetic left ventricular apex. She was discharged on aspirin as well as an ACE inhibitor and warfarin to prevent LV thrombus.ConclusionsSCAD and TTS can co-exist in patients with chest pain. It is important to identify SCAD in patients with TTS as it may affect their short as well as long-term management.
