A male patient aged 73 years with a history of type 2 diabetes and hypertension was found to have a mid–right coronary artery (RCA) lesion on coronary angiography. As a result, the patient was wired with a workhorse 0.14” coronary guidewire, and a rapid exchange balloon (2.75 × 12 mm) was tracked to the lesion. When the balloon was inflated, 2 dilatations were noted (Figure, A). The patient developed proximal RCA dissection and sudden clinical and hemodynamic deterioration. As a result, the patient required stent placement with 2 overlapping stents using intravascular ultrasonography guidance. The erroneous inflation was probably due to improper gluing of the proximal end of the balloon to the shaft (Figure, B). Coronary balloon-related complications like rupture and entrapment have been described in the literature, but dilatation of the glued part of the balloon has not, to our knowledge, been reported.1,2
