Between November 1986 and March 1987, 14 patients (11 men and three women, aged 48-84 years, mean 71.3 years) had percutaneous transluminal balloon dilatation of calcific aortic valve stenosis. Peak transvalvar pressure gradients were reduced from a mean of 81.4 mm Hg (25-122 mm Hg) to a mean of 44.8 mm Hg (range 19-63 mm Hg). Calculated valve opening area was increased from a mean of 0.48 (0.3-0.86) cm2 to 0.75 (0.6-1.16) cm2. All but one patient were in stage III or IV (New York Heart Association) and most improved by about one stage. There were no complications that could be ascribed to the procedure. Blood transfusion was not required.
1986年11月至1987年3月期间，14例患者（11例男性，3例女性，年龄48 - 84岁，平均71.3岁）接受了经皮腔内球囊扩张术治疗钙化性主动脉瓣狭窄。跨瓣峰值压力梯度从平均81.4 mmHg（25 - 122 mmHg）降至平均44.8 mmHg（范围19 - 63 mmHg）。计算得出的瓣膜开口面积从平均0.48（0.3 - 0.86）cm²增加至0.75（0.6 - 1.16）cm²。除1例患者外，所有患者均处于纽约心脏协会III期或IV期，且大多数患者改善了约一个阶段。未出现可归因于该手术的并发症。无需输血。
