The aim of this study was to examine the use of saphenous vein grafts (SVGs) for retrograde crossing during chronic total occlusion (CTO) percutaneous coronary intervention (PCI).The use of SVGs for retrograde crossing during CTO PCI has received limited study.A total of 1,615 retrograde CTO PCIs performed between 2012 and 2019 at 25 centers were examined. Clinical, angiographic, and technical characteristics and procedural outcomes were compared among retrograde cases via SVGs (SVG group) versus other collateral vessels (non-SVG group).Retrograde CTO PCI via SVGs was performed in 189 cases (12%). Patients in the SVG group were older (mean age 70 ± 9 years vs. 64 ± 10 years; p 0.01) and had higher rates of prior myocardial infarction (62% vs. 51%; p 0.01) and prior PCI (81% vs. 70%; p 0.01). They were more likely to have moderate or severe calcification (81% vs. 65%; p 0.01) and moderate or severe tortuosity (53% vs. 44%; p = 0.02) and had similar J-CTO (Multicenter CTO Registry in Japan) scores (3.2 ± 1.0 vs. 3.1 ± 1.1; p = 0.13) but higher PROGRESS-CTO (Prospective Global Registry for the Study of Chronic Total Occlusion Intervention) scores (4.7 ± 1.7 vs. 3.1 ± 1.1; p 0.01). Technical (85% vs. 78%; p = 0.04) and procedural (81% vs. 74%; p = 0.04) success rates were higher in the SVG group, with no difference in in-hospital major adverse events (6.4% vs. 4.4%; p = 0.22). Contrast volume was lower in the SVG group (225 ml [173 to 325 ml] vs. 292 ml [202 to 400 ml]; p 0.01).Use of SVGs for retrograde crossing is associated with higher rates of technical and procedural success and similar rates of in-hospital major adverse cardiac events compared with retrograde CTO PCI via other collateral vessels.

The impact of peripheral artery disease (PAD) in patients undergoing chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study. We reviewed 3999 CTO PCIs performed in 3914 patients between 2012 and 2018 at 25 centers, 14% of whom had a history of PAD. We compared the clinical and angiographic characteristics and procedural outcomes of patients with versus without history of PAD. Patients with PAD were older (67 ± 9 vs 64 ± 10 years, P < .001) and had a higher prevalence of cardiovascular risk factors. They also had more complex lesions as illustrated by higher Japanese CTO score (2.7 ± 1.2 vs 2.4 ± 1.3, P < .001). In patients with PAD, the final crossing technique was less often antegrade wire escalation (40% vs 51%, P < .001) and more often the retrograde approach (23 vs 20%, P < .001) and antegrade dissection/reentry (20% vs 16%, P < .001). Technical success was similar between the 2 study groups (84% vs 87%, P = .127), but procedural success was lower for patients with PAD (81% vs 85%, P = .015). The incidence of in-hospital major adverse cardiac events was higher among patients with PAD (3% vs 2%, P = .046). In conclusion, patients with PAD undergoing CTO PCI have more comorbidities, more complex lesions, and lower procedural success.

Background The effect of perioperative bridging therapy on risks of ischemic cardiac events and major bleeding complications in patients on dual antiplatelet therapy (DAPT) following percutaneous coronary intervention (PCI) remains undefined. Methods We report on 60 consecutive patients between 2010 and 2017 who required cardiac (CS; n = 15) or non-cardiac (NCS; n = 45) surgeries following PCI at our institution. Short-acting intravenous (IV) antiplatelet (APT) bridging with eptifibatide, tirofiban and cangrelor were instituted after DAPT interruption. Results All patients were men with multiple atherosclerosis risk factors. An acute coronary syndrome indication (56.7%) was the most common PCI indication in the CS and NCS groups. Drug-eluting stents were used in 93.33% and 95.56% of the above groups, respectively. The median duration from PCI to CS and NCS were 11.17 and 18.25 months, respectively and 38.33% of all surgeries were performed within 6 months of the index PCI. Most patients were on background aspirin (83.33%) and clopidogrel (81.67%) and median duration of DAPT interruption was 7 days. Median duration of perioperative IV APT bridging was 3 days for CS and 5 days for NCS groups. In the CS group, two patients (13.33%) had non-fata myocardial infarction (MI), and four (26.67%) had clinically significant bleeding. No patients had perioperative stent thrombosis. In the NCS group, one patient (2.22%) had stent thrombosis; four (6.67%) had myocardial infarction, and five (11.11%) clinically significant bleeding. Conclusions Despite using IV APT as bridging therapy during perioperative DAPT interruption in post-PCI patients, postoperative cardiac events and bleeding complications can still occur.

Background The long-term outcome of Jetstream atherectomy (JA) with or without adjunctive drug coated balloons (DCB) in a real-world setting remains unknown. We report 16-month target lesion revascularization (TLR) rates on patients treated for femoropopliteal (FP) artery disease with JA in a single center by one operator. Methods From 1/1/12 to 8/24/16 a total of 311 procedures were performed with atherectomy by a single operator at a single center. Of these procedures, 75 met inclusion and exclusion criteria. This report evaluates the outcomes of these 75 patients treated at index and who were followed up to 16 months. The primary endpoint of the study was clinically driven TLR. Patients were stratified by the use of DCB (vs angioplasty (PTA)) post-JA. TLR was calculated by excluding bailout stenting as TLR. Survival analysis for TLR over time was plotted. Results 75 patients (49.3% male, mean age 68.0 years, 54.7% diabetes) with de novo or restenotic FP lesions whose symptoms were classified as Rutherford category I–V were enrolled. Adjunctive PTA was performed on 50 patients (26 de novo, 13 in-stent restenosis, 3 non-stent restenosis, 8 mixed lesions) and adjunctive DCB (LUTONIX® 24, IN.PACT® 1) on 25 patients (21 de novo, 1 in-stent restenosis, 2 non-stent restenosis, 1 mixed lesion) (p = 0.0249). There was no difference in the median treated length between the adjunctive PTA (15 cm) and DCB (10 cm) groups (p = 0.0530). The estimated freedom from TLR (fTLR) was significantly higher with atherectomy and adjunctive DCB compared to atherectomy with adjunctive PTA at 12 months (94.7% vs 68.0%, p = 0.002) and 16 months (94.4% vs 54%; p = 0.002). Conclusions In a single center cohort of JA reflecting real-world practice, JA with DCB had a superior TLR rate up to 16-month follow-up when compared to JA with PTA in treating all comers FP arterial disease.
