This study assessed clinical and angiographic restenosis following the deployment of the long coronary Wallstent. Between May 1995 and June 1997, 182 Wallstents were deployed in 162 vessels in this unit. Forty‐eight percent had an unstable coronary syndrome and 94% had AHA grade B or C lesions. The mean lesion length was 37 ± 20 mm and the mean stent length was 48 ± 20 mm. The procedural success rate was 99% and the primary success rate was 93%. Six in‐patients suffered subacute stent thrombosis, the majority being in the era of anticoagulation rather than antiplatelet regimes. Seventy‐three percent remained free of major adverse clinical events in the follow‐up period, but 41% had angiographic restenosis. The Wallstent can be deployed in complex lesions with a high primary success rate and an acceptably low restenosis rate. The optimal management of in‐stent restenosis remains to be defined. Cathet.
