{Abstract}: We report an extremely rare case of spontaneous closure of grade 1 coronary perforation by the snowplow phenomenon during the revascularization of a subtotal occlusion in the left anterior descending coronary artery. Coronary artery perforation is usually a nightmare during coronary intervention in the cardiac catheterization laboratory. While large coronary perforation requires the deployment of a covered stent, small perforations require heparin reversal, prolonged balloon inflation, deployment of small coils, or gel foam closure. The coronary segment with a small perforation was stented with a drug-eluting stent (DES), which might have resulted in the shifting of the fatty plaque toward the perforation and subsequently sealing the coronary perforation.
