Abstract Balloon imprint during angioplasty is often seen, but not at all inflations. We prospectively studied 235 consecutive patients undergoing 282 PTCAs during a 4‐month period, who were divided into two groups: those with balloon imprint during inflation (159 patients, 190 lesions; 67%) and those without (76 patients, 92 lesions; 33%). Clinical and lesion characteristics and immediate outcome were compared. Patients undergoing urgent PTCA had less balloon imprint than those undergoing nonurgent PTCA (14.2% vs. 28.3%; P < 0.005). Although not reaching statistical significance, younger patients and diabetic patients tended toward less balloon imprint ( P < 0.06). Patients with observed imprint had less visible thrombus at lesion site (31.1% vs. 42.4%; P < 0.05), and a tendency without statistical significance toward more dissections but less acute closure was observed ( P < 0.07). In addition, more stents were implanted in the imprint group (79.5% vs. 66.3%; P < 0.02). Patients needing pressure > 6 atm to break the imprint had more eccentric lesions (68% vs. 27.1%; P < 0.000) and more dissections (13.9% vs. 5.1%; P < 0.03) than those needing lower pressure. Patient and lesion characteristics may determine the appearance of balloon imprint at PTCA, which in turn influences the procedure and its immediate outcome.
