Our case illustrates a patient who suffered a pulmonary artery rupture despite previous total artificial heart implantation and replacement with orthotopic heart transplant. Pulmonary artery rupture during or following cardiac surgery has been reported to occur due to both pulmonary artery catheter use and surgical technique. Our case is the first to demonstrate the occurrence of this complicat...

A seven-week-old infant with aortic origin of the right pulmonary artery and patent ductus arteriosus is reported. During preoperative studies, a balloon catheter was used to occlude the ductus arteriosus in order to define the status of the pulmonary vascular bed. Corrective operation was performed by anastomosis of the anomalous right pulmonary artery to the main pulmonary trunk and ligation ...

The pulmonary vascular changes caused by distention of the pulmonary artery with the lumen fixed were compared to those produced by occlusive arterial distention. In 13 methane-anesthetized dogs, nonocclusive distention was produced by distention of a corrugated rubber cuff around a hollow metal cylinder affixed to the end of a cardiac catheter. In 10 other dogs, occlusive distention was produc...

Embolization of central catheter fragments is a rare but well-documented complication of indwelling vascular devices. We describe a unique case of a catheter fragment migrating through the pulmonary vasculature after indwelling reservoir catheter removal in a 42 year-old female with metastatic breast cancer. The catheter fragment was initially visualized in the right upper lobe pulmonary artery...

experience recently. In our case, a 48-year-old man with acute myocardial infarction had a 7F Swan-Ganz catheter placed in the pulmonary artery. Intracardiac knotting was discovered and the catheter was withdrawn slightly leaving the tip in the pulmonary artery. The second day, pericarditis was detected and on the fourth, a small left pleural effusion appeared on roentgenogram. To exclude a pos...

Two patients with respiratory failure had consistently reproducible findings on insertion of flow directed pulmonary artery catheters which led to the subsequent diagnosis of pulmonary embolus. Occlusion of the catheter tip and development of a rising "overwedge" tracing on deflation of the balloon may mean the catheter tip has become embedded in clot. When combined with the inability to obtain...

Pulmonary artery sarcoma is highly malignant and easily metastasizes to the systemic organs. Both the introduction of novel diagnostic procedures and the development of new treatment modalities are required to achieve long-term survival. Several studies have shown that platelet-derived growth factor receptor α (PDGFRα) gene amplification is frequently observed in pulmonary artery sarcoma. PDGFR...

Fifty-six combined right and left heart catheterizations in normal dogs and clogs with experimental mitral stenosis failed to show a significant positive correlation between pulmonary artery wedge pressure and pulmonary vein pressure when the latter was below approximately 17 mm. Hg. Evidence is presented which suggests that the wedged catheter outlets are totally occluded in many instances in ...
