Data on the clinical outcomes comparing synthetic fluorocarbon polymer polytetrafluoroethylene- (PTFE, GraftMaster) and polyurethane- (Papyrus) covered stents (CSs) to seal coronary artery perforations (CAPs) are limited. We aimed to evaluate 30-day and 1-year clinical outcomes after PCI complicated by CAP and treated with CS. We assessed 106 consecutive patients with successful CAP sealing (122 CSs): GraftMaster (51 patients, 57 CSs) or Papyrus CS (55 patients, 65 CSs). The primary endpoint was the occurrence of major adverse cardiac events (MACE), defined as the composite of cardiac death, target lesion revascularisation (TLR), and myocardial infarction (MI). The mean age of subjects was 69 ± 9.6 years (53.8% males). No significant differences were identified between the GraftMaster and Papyrus groups at the 30-day follow-up for MACE, cardiac death, MI and stent thrombosis (ST), while significantly lower rate of TLR and TVR (p = 0.02) were confirmed in the Papyrus group. At one year, differences remained similar between stents for MACE, a trend towards a lower rate of TLR (p = 0.07), MI (p = 0.08), and ST (p = 0.08), and higher for cardiac death (p = 0.07) was observed in the Papyrus group. This real-life registry of CAP illustrated that the use of Papyrus CS is associated with lower rates of TLR and TVR at 30-day follow-up in comparison to the GraftMaster CSs and no significant differences between both assessed CS at one year of follow-up.

Background: Long-term outcomes of balloon aortic valvuloplasty (BAV) in patients with severe symptomatic aortic stenosis (AS) are poor, and this procedure needs to be repeated in selected cases. Aims:We aimed to investigate the safety and efficacy of repeated BAV (reBAV). Methods:We included consecutive patients who underwent reBAV in three Polish centers between 2010 and 2019. Baseline clinical, echocardiographic, procedural, and outcome data were analyzed.Results: Thirty-five patients (median age 81.5 years, 57.1% women) who underwent reBAV were enrolled. In 42.9% of the patients, index BAV was considered a palliative treatment, and in 54.3% a bridge to definitive treatment. Index BAV decreased peak aortic valve gradient (pAVG) from a median of 78.0 mm Hg to 46.0 mm Hg (P <0.001). After a mean of 255.8 days, reBAV was performed. In most cases (71.4%), the reason for reBAV was the worsening of heart failure symptoms and in 54.3% of patients, reBAV was still considered a palliative option. A decrease in pAVG max from a median of 73.0 mm Hg to 45.0 mm Hg (P <0.001), comparable to index BAV, was observed. The frequency of complications were numerically higher for repeated procedures. During the median (IQR) follow-up of 403.0 (152.0-787.0) days from the index procedure, 80.0% of the patients died.Conclusions: Acute hemodynamic results of reBAV are comparable to those achieved during index BAV. However, reBAV may carry an increased risk of complications. Moreover, mortality is high due to unfavorable risk profiles or delays in receiving definitive therapy.
