ABSTRACT
Aims:
We sought to determine the impact of post-dilation (PD) on clinical outcomes in a large cohort of patients treated only with the Absorb Bioresorbable Vascular Scaffold (BVS).Methods andresults:
We evaluated all consecutive patients enrolled in the multicentre, single-arm ABSORB EXTEND study up to June 2013. The study allowed treatment of up to two coronaries (diameter 2.0 to 3.8 mm) and the use of overlapping (lesion length ²28 mm). Patients with severe lesion calcification/tortuosity were excluded. Aggressive lesion predilation (balloon to artery ratio of 0.9-1.0) was mandatory, and PD was left to the operators discretion. Patients were grouped according to whether PD was performed or not, and the one-year incidences of MACE and scaffold thrombosis were compared. A total of 768 patients were enrolled in the study; PD was performed in 526 (68.4%). There were no significant differences between the PD group and non-PD group in the majority of baseline characteristics, including the presence of mod-erate calcification and of B2/C lesions. Lesion length was similar (12.3±5.1 mm vs. 12.1±5.3 mm, p=0.6), as was RVD (2.6 mm for both groups, p=0.2). Residual in-scaffold stenosis (15.5±6.4% with PD, 15.0±6% without PD, p=0.3) and the need for bail-out scaffold/stent (4.2% with PD, 4.6% without PD, p=0.8) were comparable. Acute gain was higher in the non-PD group (1.14±0.3 mm vs. 1.21±0.4 mm, p=0.02). Clinical device success was 98.9% in both groups. At one year, there was no difference in MACE (5.4% in the PD group vs. 2.5% in the non-PD group, p=0.1). All individual components of TLR, death, and MI were similar as well as definite/probable scaffold thrombosis between the two groups...
