Key Clinical Message Left‐atrial septal pouch (LASP) is a newly described anatomical variant caused by incomplete fusion of the septa primum and secundum. This case visualizes LASP as a potential nidus for blood stasis and cardiac embolism and highlights the need for consideration of TEE in the work up of cryptogenic stroke.

A large proportion of ischemic strokes have an undetermined cause and are considered “cryptogenic.” A left atrial septal pouch (LASP) develops due to incomplete fusion of the septa primum and secundum, forming a pocket at the interatrial septum. It can be a potential site of blood stasis with resultant thrombus formation. LASP has a higher prevalence among patients who present with cryptogenic stroke, but it is rare to visualize a thrombus in the LASP. We present a case of stroke with visualization of a LASP with …

Takotsubo cardiomyopathy (TCM), also known as stress cardiomyopathy, occurs in the setting of catecholamine surge from an acute stressor. This cardiomyopathy mimics acute myocardial infarction in the absence of coronary disease. The classic feature of TCM is regional wall motion abnormalities with characteristic ballooning of the left ventricle. The etiology of the stressor is often physical or emotional stress, however iatrogenic causes of TCM have been reported in the literature. In our review, we discuss medica…

As cardiac implantable electronic devices (CIED) become more prevalent, it is important to acknowledge potential electromagnetic interference (EMI) from other sources, such as internal and external electronic devices and procedures and its effect on these devices. EMI from other sources can potentially inhibit pacing and trigger shocks in permanent pacemakers (PPM) and implantable cardioverter defibrillators (ICD), respectively. This review analyzes potential EMI amongst CIED and left ventricular assist device, de…
