Percutaneous transluminal coronary angioplasty.

DR. Andreas Gruntzig and his colleagues are to be congratulated. In this issue of the Journal, they report on their experience with their first 50 patients undergoing percutaneous transluminal coronary angioplasty. The report provides evidence that in carefully selected and prepared patients, and in the hands of an experienced team, balloon angioplasty can effectively dilate highly stenotic coronary vessels and provide immediate improvement in myocardial perfusion and myocardial performance, as measured both subjectively and objectively. Moreover, this improvement can persist for six months or longer. Thus, percutaneous transluminal coronary angioplasty can be seriously considered as a promising new technic. . . .
