A new stenting technique for bifurcation lesions a nine‐patient case series

Abstract

This study describes and reports preliminary outcomes using kissing T-stenting and small protrusion (K-TAP), a novel modification of traditional T-stenting and small protrusion (TAP). Nine patients who were treated with K-TAP between May 2008 and February 2012 at two hospitals were retrospectively included in this study. The primary endpoints were angiographic success, procedural success, and the composite 30-day and long-term occurrences of major adverse cardiac events (MACEs), which consisted of death, coronary artery bypass graft surgery, repeated percutaneous coronary intervention of the target vessel, and non-Q-wave and Q-wave myocardial infarctions. Data were obtained from the review of institutional databases, folder auditing, a telephone survey of the patients, and the review of angiograms. Angiographic success and procedural success were achieved in all patients. The mean fluoroscopy time for the total procedure was 24.1 min (range 20-28). No complications occurred during the procedures. The MACE rate during the mean follow-up period of 102 weeks (range 22-196 weeks) was 0%. K-TAP, a new coronary bifurcation stenting method, has favorable angiographic and procedural success rates and a low early post-procedure MACE rate. Further studies are needed to evaluate the clinical efficacy of the K-TAP method.
