A survey was conducted to assess the knowledge and trends of use of the pulmonary artery catheter amongst intensive care practitioners in Australasia. A 31-item multiple choice questionnaire, identical to one previously trialled in studies in the United States and Europe, was distributed to all registered intensive care specialists and trainees working in intensive care units in Australasia. Fi...

in accordance with the article of Fletcher et a13 who systematically tested the accuracy of this catheter system in humans. He also found a consistent underestimation of the fiberoptic pulmonary artery catheter SvO2 values below 50% compared with direct spectophotometry and proposed two equations to adjust the catheter measurements: (1) Catheter=-11.68+1.1892XCOOX (2) Catheter=COOX-210.997 exp ...

Wedged catheter pressures (PC) were compared with those in the aorta, left atrium, and pulmonary artery before and after production of mitral stenosis, insufficiency, and pulmonary embolism. In general it was found that "PC" pressures follow closely changes in left atrial pressures even when pulmonary artery pressure changes in an opposite direction (for example, pulmonary embolism). However, p...

Objective. To report the experience of a percutaneous technique for retrieving fractured peripherally inserted central catheter (PICC) segments migrating into the heart or the pulmonary artery. Method. From April 2013 to July 2015, we performed percutaneous retrieval of fractured PICC segments migrating into the heart or the pulmonary artery in five cancer patients who had undergone chemotherap...

pulmonary arteriovenous malformations are rare clinical entities thai are associated with right to left shunts, and are often clinically presented by the triad of dyspnea, cyanosis, and digital clubbing. currently, transcatheter embolization of fistula is gaining increasing popularity as the superior therapeutic option. in certain situations, however, surgery is preferred. two cases of direct p...

We present the rare case of a patient with pulmonary hypertension in the context of the stiff left atrial syndrome after extensive catheter ablation, a unique constellation characterized by high pulmonary artery and pulmonary artery wedge pressures due to left atrial dysfunction but normal left ventricular end-diastolic pressure, normal mitral valve, and absence pulmonary vein stenosis. This pa...

A new performed, semi-rigid, polyethylene catheter, with built-in torque control, has been devised for entry to the pulmonary artery in complete transposition of the great arteries. It has been used 19 times in 17 patients: 18 times the pulmonary artery was entered from the right atrium (via the left atrium and ventricle) in a time between 40 s and 15 min (median 5 min); the patients' ages were...

Pulmonary artery rupture by a flow-directed balloon-tipped catheter is a rare complication if guidelines for insertion of catheters are strictly applied. It should be stressed that the need for a "confirmed" wedge pressure should be weighed against the very real risk of this potentially fatal complication. Users of this catheter should expect and anticipate distal migration of the catheter tip....
