Long-term clinical and angiographic outcome of T-and protrusion technique with ultrathin strut drug eluting stents.

OBJECTIVES

Data about coronary bifurcations treated with ultrathin strut drug-eluting stents (DES) using T-and-protrusion (TAP) technique is limited.

METHODS

In this study, a total of 84 consecutive patients, who underwent bifurcation percutaneous coronary intervention (PCI) with TAP technique using Orsiro® DES (Biotronik, Berlin, Germany), were included. All pre- and post-procedural data, as well as 1- and 2-year follow-up angiograms, were analyzed. Primary endpoints were procedural success and target lesion failure (TLF); secondary endpoints were all-cause mortality and major adverse cardiac and cerebrovascular events (MACCE) during follow-up.

RESULTS

Procedural success was achieved in 100% of cases. TLF rate was higher in patients presented with acute coronary syndrome compared to the ones with chronic coronary syndrome (19% vs. 5%  = 0.09). All-cause mortality was 30% during follow-up, from which 26% was due to non-cardiovascular cause, and the MACCE rate was 46%.

CONCLUSIONS

Coronary bifurcations treated with ultrathin strut DES showed good short-term results and were associated with acceptable cardiovascular mortality. However, in these long-term patients, the rate of MACCE and non-cardiovascular death were rather high.
