摘要:

AbstractThe idea of perfusing the distal coronary artery with arterial blood during balloon dilatation was implemented in early experimental coronary angioplasty but then abandoned. We pursued this concept in an animal model using a specially designed roller pump. The pump delivers blood from a femoral artery catheter through the central lumen of a balloon catheter occluding a coronary artery. Perfusion of large proximally occluded coronary arteries for at least 60 min was possible in 8 of 11 heparinized dogs. Hemolysis occurring in the pump system due to the small catheter lumen proved a minor problem. For a limited period of time, occluded coronary arteries can be adequately perfused with arterial blood by this percutaneous system that is readily applicable in any catheterization laboratory. Its use is conceivable not only for temporary treatment of acute complications during angioplasty but also for prolonged balloon dilatations of spastic or thrombosed coronary arteries.

摘要:

AbstractIn the period between October 1980 and December 1982 we evaluated the outcome of percutaneous transluminal graft and coronary angioplasty when a Judkins type guiding catheter (J gc) was initially used, but the lesion could not be passed and a subsequent attempt was made with the El Gamal guiding catheter (EG gc). Seven of twelve attempts to dilate stenotic coronary artery bypass grafts failed. The EC gc was tried in six, five were successfully dilated; one failed.Our initial attempts to dilate a stenosed right coronary artery failed in 16 of 68 attempts. The EG gc was attempted in 14. We successfully dilated ten, two dissections required emergency coronary artery bypass grafting (CABG); two failed. Our initial attempts to dilate a left anterior descending artery stenosis failed in 14 of 109 attempts. Six lesions were passed when the EG gc was tried. Five were successfully dilated, and one acute dissection required emeregency CABG; eight failed. The EG gc is useful for transluminal angioplasty of stenosed aortocoronary bypass grafts. It increased the success rate of right coronary artery dilatation from 76–91%, but was of limited use in dilatation of left anterior descending lesion

摘要:

AbstractAutomatic ambulatory blood pressure monitoring is a valid and reliable tool for intermittent noninvasive assessment of blood pressure over a 24‐hour period. However, reporting devices to retrieve data from the recording device are dedicated to one task and are expensive. Because of this, we have developed computer programs for a popular inexpensive microcomputer that retrieves data from the Del Mar Pressurometer III, an R‐wave gated automatic ambulatory blood pressure monitoring device. Furthermore, the derived data may be edited, computed to derive statistics, stored, retrieved, displayed, and reported in both numerical and graphical format. This same hardware is used for multiple other ta
