BackgroundAortoiliac occlusive disease, which is also referred to as Leriche syndrome, is a chronic atherosclerotic occlusive disease that occurs at the level of the aortic bifurcation. It is often thought to present with a triad of clinical symptoms: (1) intermittent lower extremity vascular claudication, (2) impotence, and (3) weak/absent femoral pulses.Case presentationWe report a case of a 47-year-old Caucasian woman who presented with an acute inferior ST-elevation myocardial infarction. During percutaneous transluminal angioplasty, our patient suddenly developed severe bilateral lower extremity pain, absent femoral pulses, and cool extremities. Distal aortogram revealed 95% stenosis with an apple core-like lesion in the mid-abdominal aorta. Stent placement resulted in improved blood flow to the distal aortic segment and resolution of symptoms.ConclusionsThe presence of significant peripheral vascular disease, significant cardiac risk factors, and/or difficulty accessing the femoral artery should caution a transfemoral approach during percutaneous transluminal angiography. This approach may precipitate aortoiliac occlusion and/or thromboembolism to the lower extremities. We encourage interventional cardiologists to (1) take extra caution when manipulating the wire and catheter and (2) strongly consider using a transradial approach in such patients.

A 52-year-old man, without previous disease, presented with dysphagia, dyspnoea, high fever and sore throat after peritonsillar abscesses drainage. Physical and complementary examinations were consistent with pericarditis, mediastinitis, pneumonia and pleuritis. Blood cultures grew Eikenella corrodens resistant to clindamycin and amikacin. We emphasize the pathogenic potential of Eikenella corrodens. To the best of our knowledge, this is the first reported case of this organism as a pathogen in intrathoracic infections after peritonsillar abscesses drainage.

We present the case of a 79-year-old patient who required an urgent mitral clip for treatment of recurring acute decompensated pulmonary edema as a result of severe mitral regurgitation. An augmented reality (AR) platform, Proximie, was used to virtually connect an interventional cardiologist based at the American University of Beirut Medical Center (AUBMC) with a medical device expert in Europe intraoperatively in order to successfully perform the life-saving procedure using a novel medical device. The Proximie SystemProximie is an augmented reality platform that enables clinicians to connect in real-time in order to share expertise and provide mentorship [2].A live video feed of the procedure is captured using a camera, a capture card and a laptop or tablet. A remote expert using a laptop or tablet with a Chrome browser can access the feed in real-time via the online Proximie platform (Figure 1). The technology is end-toend encrypted for security and fully HIPAA and GDPR compliant. Proximie's augmented reality toolbox can be employed by the remote user to annotate the live feed or virtually reach into the field to indicate structures or provide precise guidance in real-time. Crucially, these tools enable a remote mentor to provide mentorship both by voice and by demonstration.
