Baden-Baden, Köln, New York, Verlag Gerhard Witzstock, 1977, 8°, 100 pp., zahlr. Abbildungen. First Edition! Grüntzig developed the first successful balloon angioplasty for expanding lumens of narrowed arteries. "In percutaneous transluminal coronary angioplasty, a catheter system is introduced through a systemic artery under local anesthesia to dilate a stenotic artery by controlled inflation of a distensible balloon. "Over the past 18 months, we have used this technic in 50 patients. The technic was successful in 32 patients, reducing the stenosis from a mean of 84 to 34 per cent (P<0.001) and the coronary-pressure gradient from a mean of 58 to 19 mm Hg (P<0.001). Twenty-nine patients showed improvement in cardiac function during follow-up examination. Because of acute deterioration in clinical status, emergency bypass was later necessary in five patients; three showed electrocardiograpic evidence of infarcts. "Patients with single-vessel disease appear to be most suitable for the procedure, and a short history of pain indicates the presence of a soft (distensible) atheroma likely to respond to dilatation. We estimate that only about 10 to 15 per cent of candidates for bypass surgery have lesions suitable for this procedure. A prospective randomized trial will be necessary to evaluate its usefulness in comparison with surgical and medical management. " Abstract (N Engl J Med 301:61-68, 1979). "Prior to the 1979 paper Grüntzig published a preliminary, abbreviated paper on the method: "Perkutane Dilatation von Coronarstenosen - Beschreibung eines neuen Kathetersystems.
