There is a growing interest in using point-of-care transesophageal echocardiography (TEE) during cardiac arrest. TEE is effective at identifying the etiology of sudden cardiovascular collapse and guiding management during the resuscitation. ⋯ ECPR requires percutaneous vascular access for the implantation of veno-arterial extracorporeal membrane oxygenation circuit. We present a case of prolonged cardiac arrest in which rescue TEE was pivotal in narrowing the differential diagnosis, monitoring of mechanical chest compression performance, and guiding cannulation for ECPR.

Case Reports
Bicuspid aortic valve with right-sided aortic arch aneurysm and Kommerell's diverticulum.
Bicuspid aortic valve (BAV) is a common congenital cardiac malformation, frequently combined with ascending aorta dilation. However, isolated abnormalities of the aortic arch are less frequent in BAV patients. Here, we present a rare case of BAV combined with right-sided aortic arch aneurysm, aberrant left subclavian artery, and Kommerell's diverticulum, diagnosed by echocardiography and computed tomography angiography. The patient was followed-up regularly because of the life-threatening risks of aortic arch aneurysms.

Lung ultrasound (LUS) at the point-of-care is a new method that is increasingly used in neonatology. The aim of this study was to determine the utility of the addition of LUS prior to the interhospital transport of neonates with respiratory failure. ⋯ LUS may be a reliable imaging technique for differentiating the causes of respiratory failure before neonatal transport. Use of LUS may optimize the care of infants during transport.

Splenosis is an unusual condition representing auto-transplantation of splenic tissue following splenic trauma or surgery. When detected on imaging studies, the splenosis deposits are usually misinterpreted as pathological masses. ⋯ Ultrasound practitioners should be aware of this condition when an unusual abdominal or pelvic mass is encountered in a patient with a history of splenic trauma or surgery. CEUS is ideally suited to confirming the diagnosis.
