Case ReportsSuccessful resuscitation of a patient with critical aortic stenosis and cardiac arrest by peripheral cardiopulmonary support system.
Patients with critical aortic stenosis have an increased risk of complications during diagnostic cardiac catheterization, and those who arrest are particularly difficult to resuscitate. Recent advances in therapeutic techniques may change this unfavorable prognosis, as it is illustrated in the presented case. ⋯ Conventional cardiopulmonary resuscitation for 45 minutes failed to restore cardiac function and rhythm, which had degenerated to ventricular fibrillation, electromechanical dissociation, and asystole. Peripheral cardiopulmonary support system restored cardiac rhythm and blood pressure, with a subsequent successful aortic valve replacement.

ReviewUse of percutaneously inserted cardiopulmonary bypass in the cardiac catheterization laboratory.
A cardiopulmonary bypass system that can be percutaneously inserted is available. In addition to its use in stabilization of severely hemodynamically compromised patients, it has many uses in cardiology including use as an adjunct to high-risk interventional procedures. The purpose of this report is to communicate our experience with cardiopulmonary bypass in the Catheterization Laboratory and discuss technique, indications, and potential complications.

Case ReportsPlatypnea-orthodeoxia as a cause of unexplained hypoxemia in an 82-yr-old female.
We describe an 82-yr-old patient with platypnea-orthodeoxia without identifiable lung disease in whom the diagnosis was suspected because of clinical history, echocardiography, and orthostatic measurement of arterial blood gases. Recumbent and upright cardiac catheterization techniques confirmed the presence of orthostatic variation in the degree of right to left shunt across the fossa ovalis. This was successfully treated by surgical closure of the interatrial communication in the region of the fossa ovalis.

We report three patients who had intravascular catheter fragments removed using an easily made snare device fashioned from a 0.038 inch movable-core J-wire and a multi-purpose catheter. The device is easily manipulated and facilitates safe removal of embolized catheters.
