It was reported that the procedure was to treat a heavily calcified, moderately tortuous, 100% stenosed, de novo, lesion in the left anterior descending (lad) artery.A 1.2x12mm mini trek balloon dilatation catheter (bdc) was advanced and inflated 2 to 3 times, but the balloon ruptured at 12 atmospheres due to the heavy calcification in the lesion.There was no adverse patient effect and no clinically significant delay in the procedure.Several other balloons (1.2x12mm, 2.0x15mm and 2.5x15mm) were used to successfully complete the procedure.No additional information was provided.
