MAJICMayo-Japan Investigation for Chronic Total Occlusion. A study which examined the frequency and timing of restenosis and reocclusion after treating chronic total coronary artery occlusions (CTOs) with balloon angioplasty and Wiktor stent implantation.
Patients undergoing balloon angioplasty showed 30% restenosis and 1% reocclusion the following day versus 2% restenosis and no reocclusion in stent patients the following day. The cumulative reocclusion rate was significantly lower in the stent group than in the balloon group at 6 months (2% versus 9%, P <.05).
