Does a pulmonary-artery-seeking catheter provide high success rates and safety in patients undergoing percutaneous selective pulmonary arteriography?
The use of a pigtail-designed pulmonary-artery-seeking catheter offers a high success rate (98.4%) and avoids myocardial perforation during percutaneous selective pulmonary arteriography.

May support selective pulmonary arteriography with dedicated catheter in experienced hands; leaves open comparative trials versus standard devices.
Selective catheterization of the main pulmonary artery via the percutaneous route using a pulmonary-artery-seeking catheter was successful in 98.4% of 122 consecutive pulmonary angiographic studies in 114 patients. Complications were comparable to those encountered in other studies. Myocardial perforation, a frequently reported complication, did not occur, a factor attributed to the "pigtail" design of the catheter. This catheter was found to offer a distinct advantage in performing percutaneous selective pulmonary arteriography.
