Percutaneous coronary interventions in highly calcified atherosclerotic lesions are challenging due to the high mechanical stiffness that significantly restricts stent expansion. Intravascular lithotripsy (IVL) is a novel vessel preparation technique with the potential to improve interventional outcomes by inducing microscopic and macroscopic cracks to enhance stent expansion. However, the exact mechanism of action for IVL is poorly understood, and it remains unclear whether the improvement in-stent expansion is caused by either the macro-cracks allowing the vessel to open or the micro-cracks altering the bulk material properties.

Background: Endovascular treatment (EVT) alone was not demonstrated to be non-inferior to intravenous alteplase bridging EVT in acute large vessel occlusion (LVO) stroke. Using cerebral ischemia/reperfusion (I/R) injury model, intravenous tenecteplase (TNK) was administrated after ischemia followed by reperfusion at various time points.
Objectives: To investigate whether intravenous TNK bridging EVT vs EVT alone could improve I/R injury, and this effect may be associated with the time from TNK to reperfusion.

An 80-year-old woman with a history of B-cell non-Hodgkin lymphoma presented to the emergency department with exertional dyspnea and lower limb edema. A transthoracic echocardiogram revealed a large extracardiac mass invading the right atrium. A diagnostic transcatheter endomyocardial biopsy guided by intracardiac echocardiography was performed.

We report a case of mesenteric ischemia after thoracic endovascular aortic repair (TEVAR) for chronic type B aortic dissection performed at a different institution. Computed tomography angiography findings indicated that the previous TEVAR had been deployed distally into the false lumen. To mitigate this, a large fenestration was created between the false lumen and true lumen.
