Case ReportsRheolytic percutaneous thrombectomy for acute pulmonary embolism in a pediatric patient.
Acute massive pulmonary embolism can have significant hemodynamic effects in both adults and children. We describe the case of a 10-year-old boy who developed cardiogenic shock after suffering a massive pulmonary embolism. A significant thrombus burden was removed using a catheter-based strategy of rheolytic thrombectomy, leading to stabilization of the patient.

Case ReportsDual mechanism platypnea-orthodeoxia syndrome from severe right coronary artery stenosis and a patent foramen ovale.
Platypnea-orthodeoxia is a rare clinical syndrome characterized by hypoxemia induced during upright posture. Multiple mechanisms have been proposed to explain this clinical entity, usually involving posture-provoked intracardiac or transpulmonary shunting. ⋯ We herein describe an unusual and novel case of platypnea-orthodeoxia caused by the physiologic interaction between a severe proximal right coronary artery stenosis and a large patent foramen ovale. Percutaneous stenting of the right coronary artery and transcatheter closure of the patent foramen ovale during the same setting resulted in complete resolution of the patient's symptoms.

EditorialInterventional stroke therapy: current state of the art and needs assessment.
The primary therapeutic strategy for ischemic stroke, as for MI patients, is early reperfusion. Improvement in stroke treatment will require dedicated stroke centers to emulate MI quality indicators such as minimizing the "door-to-balloon time". A critical element in achieving this goal will be organizing the existing multidisciplinary pool of carotid interventionalists to provide the endovascular component of the acute care for ischemic stroke patients.

Multicenter StudyInterruption of blood flow during compression and radial artery occlusion after transradial catheterization.
To analyze the possible relationship between compression after transradial catheterization and radial artery occlusion. ⋯ Flow-limiting compression is a frequent finding during conventional hemostasis after transradial catheterization. Absence of radial artery flow during compression represents a strong predictor of radial artery occlusion.
