Iatrogenic coronary dissections are rare but potentially serious. Their management is complex, particularly if the dissection occurs without an angioplasty guide in the arterial lumen. In this context, angiography alone is insufficient, and endocoronary imaging is essential (using optical coherence or IVUS) to guide angioplasty when necessary (guide in the true lumen, coverage of the tear). We report here the case of an iatrogenic dissection of the right coronary artery treated with OFDI guiding.

INTRODUCTION: Percutaneous coronary intervention (PCI) with drug-eluting stents (DES) in complex coronary artery disease (CAD) has been established as the standard of care, but stent-related events are not uncommon. Sirolimus-Coated Balloon (SCB)-based angioplasty is an emerging technology, although it needs to be thoroughly evaluated compared with DES in the complex PCI setting. This study aimed to investigate the safety and efficacy of SCB-based angioplasty compared with new-generation DES in complex PCI. METHODS: Net adverse cardiovascular events (NACE: all-cause death, target lesion revascularization, non-fatal myocardial infarction, and major bleedings according to BARC classification), as a primary study endpoint was compared between SCB and new-generation DES for complex coronary lesions. RESULTS: Among 1782 patients with complex CAD, 1076 were treated with a sirolimus-coated balloon (EASTBOURNE Registry) and 706 with new-generation DES (COMPLEX Registry). After propensity score matching, a total of 512 patients in both groups were analyzed. NACE occurred more significantly in the DES group during the 1-year follow-up (10.5% vs. 3.9%, p = 0.003), mainly due to a higher risk of bleeding (6.6% vs. 0.4%, p = 0.001). The Cox model adjusted for lesion length showed a significantly lower hazard of NACE (HR: 0.23, CI [0.10, 0.52], p < 0.001) and all-cause mortality (HR: 0.07, CI [0.01, 0.66], p = 0.020) in SCB compared to DES group. CONCLUSIONS: SCB angioplasty has an advantage over DES for the treatment of complex CAD regarding NACE, significantly reducing the incidence of major bleeding without increasing ischemic endpoints. SCB may be an alternative to DES in selected patients with complex coronary lesions.

BACKGROUND: In patients with in-stent restenosis (ISR) bioresorbable vascular scaffolds (BVS) provide similar results to drug-coated balloons (DCBs) but are inferior to drug-eluting stents (DES) at 1 year. However, the long-term efficacy of BVS in these patients remains unknown. OBJECTIVES: This study sought to assess the long-term safety and efficacy of BVS in patients with ISR. METHODS: RIBS VI (Restenosis Intrastent: Bioresorbable Vascular Scaffolds Treatment; NCT02672878) and RIBS VI Scoring (Restenosis Intrastent: Bioresorbable Vascular Scaffolds Treatment With Scoring Balloon; NTC03069066) are prospective multicenter studies designed to evaluate the results of BVS in patients with ISR (N = 220). The inclusion and exclusion criteria were identical to those used in the RIBS IV (ISR of DES) (Restenosis Intra-stent of Drug-eluting Stents: Drug-eluting Balloon vs Everolimus-eluting Stent; NCT01239940) and RIBS V (ISR of bare-metal stents) (Restenosis Intra-stent of Bare Metal Stents: Paclitaxel-eluting Balloon vs Everolimus-eluting Stent; NCT01239953) randomized trials (including 249 ISR patients treated with DCBs and 249 ISR patients treated with DES). A prespecified comparison of the long-term results obtained with these treatment modalities (ie, DES, DCBs, and BVS) was performed. RESULTS: Clinical follow-up at 3 years was obtained in all (100%) 718 patients. The 3-year target lesion revascularization rate after BVS was 14.1% (vs 12.9% after DCBs [not significant], and 5.2% after DES [HR: 2.80; 95% CI: 1.47-5.36; P = 0.001]). In a landmark analysis (>1 year), the target lesion revascularization rate after BVS was higher than after DES (adjusted HR: 3.41; 95% CI: 1.15-10.08) and DCBs (adjusted HR: 3.33; 95% CI: 1.14-9.70). Very late vessel thrombosis was also more frequent with BVS (BVS: 1.8%, DCBs: 0.4%, DES: 0%; P = 0.03). CONCLUSIONS: In patients with ISR, late clinical results of DES are superior to those obtained with DCBs and BVS. Beyond the first year, DCBs are safer and more effective than BVS.

BACKGROUND: Debulking devices are often followed by a scoring or cutting balloon in percutaneous coronary intervention (PCI) for severely calcified lesions. However, there are limited data on balloon preparation after orbital atherectomy (OA) assessed using optical coherence tomography (OCT). AIM: We aimed to compare the effects of a novel scoring and cutting balloon on calcified coronary lesions with OCT. METHODS: We retrospectively examined 38 patients (38 lesions) who underwent PCI with a scoring or a cutting balloon after OA. All patients underwent pre-PCI, preballooning, postballooning, and post-PCI OCT imaging. We divided the patients into novel scoring-balloon (group A: n = 22) and cutting-balloon (group B: n = 16) groups and compared the OCT findings, including minimum lumen area (MLA) and expansion ratio (MLA divided by mean reference lumen area). RESULTS: The mean patient age was 76.1 ± 8.7 years; 71.5% were male. There were no significant differences in patient background between both groups. Regarding procedural characteristics, the maximum balloon pressure was significantly higher in group A (median 23 atm, interquartile range [IQR] 18-24 vs. 12 atm [IQR: 10-12], p < 0.01). Although a calcium score of 4 was more frequently observed in group A (86.4% vs. 62.5%, p = 0.12), post-PCI MLA was comparable between both groups (3.95 mm2 [IQR: 3.27-4.41] vs. 3.43 mm2 [IQR: 2.90-4.82], p = 0.63). Furthermore, the expansion ratio was significantly greater in group A (0.83 ± 0.20 vs. 0.68 ± 0.14, p < 0.01). CONCLUSION: Despite a higher calcium score, a larger expansion ratio was achieved in patients with a novel scoring balloon than in those with a cutting balloon after OA.

BACKGROUND: Evidence suggests that drug-coated balloons may benefit in-stent restenosis (ISR) treatment. However, the efficacy of new-generation sirolimus-coated balloon (SCB) compared with the latest generation drug-eluting stents (DESs) has not been studied in this setting. METHODS: All patients in the EASTBORNE (The All-Comers Sirolimus-Coated Balloon European Registry) and DEB-DRAGON (DEB vs Thin-DES in DES-ISR: Long Term Outcomes) registries undergoing percutaneous coronary intervention for DES-ISR were included in the study. The primary study end point was target lesion revascularization at 24 months. Secondary end points were major adverse cardiovascular events, all-cause death, myocardial infarction, and target vessel revascularization at 24 months. Our goal was to evaluate the efficacy and safety of SCB versus thin-struts DES in ISR at long-term follow-up. RESULTS: A total of 1545 patients with 1679 ISR lesions were included in the pooled analysis, of whom 621 (40.2%) patients with 621 lesions were treated with thin-strut DES and 924 (59.8%) patients with 1045 lesions were treated with SCB. The unmatched cohort showed no differences in the incidence of target lesion revascularization (10.8% versus 11.8%; P=0.568); however, there was a trend toward lower rates of myocardial infarction (7.4% versus 5.0%; P=0.062) and major adverse cardiovascular events (20.8% versus 17.1%; P=0.072) in the SCB group. After propensity score matching (n=335 patients per group), there were no significant differences in the rates of target lesion revascularization (11.6% versus 11.8%; P=0.329), target vessel revascularization (14.0% versus 13.1%; P=0.822), myocardial infarction (7.2% versus 4.5%; P=0.186), all-cause death (5.7% versus 4.2%; P=0.476), and major adverse cardiovascular event (21.5% versus 17.6%; P=0.242) between DES and SCB treatment. CONCLUSIONS: In patients with ISR, angioplasty with SCB compared with thin-struts DES is associated with comparable rates of target lesion revascularization, target vessel revascularization, myocardial infarction, all-cause death, and major adverse cardiovascular events at 2 years.

BACKGROUND: There are limited data about determinant factors of target lesion failure (TLF) in lesions after percutaneous coronary intervention (PCI) using a drug-coated balloon (DCB) for de novo coronary artery lesions, including optical coherence tomography (OCT) findings. AIMS: The present study aims to investigate the associated factors of TLF in de novo coronary artery lesions with DCB treatment. METHODS: We retrospectively enrolled 328 de novo coronary artery lesions in 328 patients who had undergone PCI with a DCB. All lesions had been treated without a stent, and both pre- and post-PCI OCT had been carried out. Patients were divided into two groups, with or without TLF, which was defined as a composite of culprit lesion-related cardiac death, myocardial infarction, and target lesion revascularisation, and the associated factors of TLF were assessed. RESULTS: At the median follow-up period of 460 days, TLF events occurred in 31 patients (9.5%) and were associated with patients requiring haemodialysis (HD; 29.0% vs 10.8%), with a severely calcified lesion (median maximum calcium arc 215° vs 104°), and with the absence of OCT medial dissection (16.1% vs 60.9%) as opposed to those without TLF events. In Cox multivariable logistic regression analysis, HD (hazard ratio [HR]: 2.26, 95% confidence interval [CI]: 1.00-5.11; p=0.049), maximum calcium arc (per 90°, HR: 1.34, 95% CI: 1.05-1.72; p=0.02), and the absence of post-PCI medial dissection on OCT (HR: 8.24, 95% CI: 3.15-21.6; p<0.001) were independently associated with TLF. CONCLUSIONS: In de novo coronary artery lesions that received DCB treatment, factors associated with TLF were being on HD, the presence of a severely calcified lesion, and the absence of post-PCI medial dissection.

BACKGROUND: Randomized controlled trials (RCTs) examining the outcomes with limus drug-coated balloons (DCBs) vs paclitaxel DCBs were small and underpowered for clinical endpoints. OBJECTIVES: This study sought to compare the angiographic and clinical outcomes with limus DCBs vs paclitaxel DCBs for percutaneous coronary intervention (PCI). METHODS: An electronic search of Medline, EMBASE, and Cochrane databases was performed through January 2024 for RCTs comparing limus DCBs vs paclitaxel DCBs for PCI. The primary endpoint was clinically driven target lesion revascularization (TLR). The secondary endpoints were late angiographic findings. Summary estimates were constructed using a random effects model. RESULTS: Six RCTs with 821 patients were included; 446 patients received a limus DCB, and 375 patients received a paclitaxel DCB. There was no difference between limus DCBs and paclitaxel DCBs in the incidence of TLR at a mean of 13.4 months (10.3% vs 7.8%; risk ratio [RR]: 1.32; 95% CI: 0.84-2.08). Subgroup analysis suggested no significant interaction among studies for de novo coronary lesions vs in-stent restenosis (Pinteraction = 0.58). There were no differences in the risk of major adverse cardiovascular events, cardiac mortality, or target vessel myocardial infarction between groups. However, limus DCBs were associated with a higher risk of binary restenosis (RR: 1.89; 95% CI: 1.14-3.12), late lumen loss (mean difference = 0.16; 95% CI: 0.03-0.28), and a smaller minimum lumen diameter (mean difference = -0.12; 95% CI: -0.22 to -0.02) at late follow-up. In addition, late lumen enlargement occurred more frequently (50% vs 27.5%; RR: 0.59; 95% CI: 0.45-0.77) with paclitaxel DCBs. CONCLUSIONS: Among patients undergoing DCB-only PCI, there were no differences in the risk of clinically driven TLR and other clinical outcomes between limus DCBs and paclitaxel DCBs. However, paclitaxel DCBs were associated with better late angiographic outcomes. These findings support the need for future trials to establish the role of new-generation limus DCBs for PCI.

BACKGROUND: Drug-coated balloon (DCB) angioplasty seems a safe and effective option for specific de novo coronary lesions. However, the beneficial effect of intravascular ultrasound (IVUS)-guided DCB angioplasty in de novo lesions remains uncertain. OBJECTIVES: This study aimed to assess the benefits of IVUS guidance over angiography guidance during DCB angioplasty in de novo coronary lesions. METHODS: A total of 260 patients with high bleeding risk who had a de novo coronary lesion (reference vessel diameter 2.0-4.0 mm, and lesion length ≤15 mm) were randomly assigned to either an IVUS-guided or an angioplasty-guided DCB angioplasty group. The primary endpoint was in-segment late lumen loss (LLL) at 7 months after procedure. The secondary endpoint was target vessel failure at 6 months. RESULTS: A total of 2 patients in the angiography-guided group and 7 patients in the IVUS-guided group underwent bailout stent implantation (P = 0.172). The primary endpoint of 7-month LLL was 0.03 ± 0.52 mm with angiography guidance vs -0.10 ± 0.34 mm with IVUS guidance (mean difference 0.14 mm; 95% CI: 0.02-0.26; P = 0.025). IVUS guidance was also associated with a larger 7-month minimal lumen diameter (2.06 ± 0.62 mm vs 1.75 ± 0.63 mm; P < 0.001) and a smaller diameter stenosis (28.15% ± 13.88% vs 35.83% ± 17.69%; P = 0.001) compared with angiography guidance. Five target vessel failures occurred at 6 months, with 4 (3.1%) in the angiography-guided group and 1 (0.8%) in the IVUS-guided group (P = 0.370). CONCLUSIONS: This study demonstrated that IVUS-guided DCB angioplasty is associated with a lower LLL in patients with a de novo coronary lesion compared with angiography guidance.

BACKGROUND: Calcified lesions are one of the most challenging cases for PCI, where optimal angiographic results and satisfying outcomes are hard to achieve. METHODS: We evaluated the baseline clinical, procedures characteristics and outcomes of patients with severe coronary artery calcification (CAC) who underwent coronary intravascular lithotripsy (IVL) and rotational atherectomy (RA). RESULTS: Respectively 152 and 238 patients who underwent IVL and RA are enrolled from January 2023 to November 2023. Regarding demographic characteristics, the gender proportion, medical history of PCI and smoke history among groups reach statistical significance. Left anterior descending and right coronary artery were the main vessels treated in both groups. The 2.5 and 3.0 mm IVL balloons and 1.5 mm burr were the most commonly used. 99.3% cases were successfully implanted drug-eluting stents after IVL balloon pre-treatment, which was higher than in the group treated with RA. During hospitalization, there were no serious adverse events in the IVL group, but there were two adverse events in the RA group. Procedural complications were higher in the RA group than the IVL group (5.5% vs. 0.7%, P = 0.027). CONCLUSIONS: IVL appears to be safe and effective for the treatment of severe CAC lesions compared to RA.

BACKGROUND: With advancements in chronic total coronary occlusion (CTO) recanalization techniques and concepts, the success rate of recanalization has been steadily increasing. However, the current data are too limited to draw any reliable conclusions about the efficacy and safety of drug-coated balloons (DCBs) in CTO percutaneous coronary intervention (PCI). Herein, we conducted a meta-analysis to confirm the efficacy of DCB in CTO PCI. METHODS: We systematically searched PubMed, Web of Science and Embase from inception to July 25, 2023. The primary outcome was major advent cardiovascular events (MACE), including cardiac death, nonfatal myocardial infarction (MI), target lesion revascularization (TLR), and target vessel revascularization (TVR). The follow-up angiographic endpoints were late lumen enlargement (LLE), reocclusion and restenosis. RESULTS: Five studies with a total of 511 patients were included in the meta-analysis. Across studies, patients were predominantly male (72.9-85.7%) and over fifty years old. The summary estimate rate of MACE was 13.0% (95% CI 10.1%-15.9%, I2 = 0%, p = 0.428). The summary estimate rates of cardiac death and MI were 2.2% (95% CI 0.7%-3.7%, I2 = 0%, p = 0.873) and 1.2% (95% CI -0.2-2.6%, I2 = 13.7%, p = 0.314), respectively. Finally, the pooled incidences of TLR and TVR were 10.1% (95% CI 5.7%-14.5%, I2 = 51.7%, p = 0.082) and 7.1% (95% CI 3.0%-11.2%, I2 = 57.6%, p = 0.070), respectively. Finally, the summary estimate rates of LLE, reocclusion and restenosis were 59.4% (95% CI 53.5-65.3%, I2 = 0%, p = 0.742), 3.3% (95% CI 1.1-5.4%, I2 = 0%, p = 0.865) and 17.5% (95% CI 12.9-22.0%, I2 = 0%, p = 0.623), respectively. CONCLUSION: Accordingly, DCB has the potential to be used as a treatment for CTO in suitable patients.

BACKGROUND: Percutaneous coronary intervention (PCI) with primary stenting, which stands for stent implantation regardless of obtaining satisfactory results with balloon angioplasty, has superseded conventional plain old balloon angioplasty with provisional stenting. With drug-coated balloon (DCB), primary DCB angioplasty with provisional stenting has shown non-inferiority to primary stenting for de novo coronary small vessel disease. However, the long-term efficacy and safety of such a strategy to the primary stenting on clinical endpoints in de novo lesions without vessel diameter restrictions remain uncertain. STUDY DESIGN: The REC-CAGEFREE I is an investigator-initiated, multicenter, randomized, open-label trial aimed to enroll 2270 patients with acute or chronic coronary syndrome from 43 interventional cardiology centers in China to evaluate the non-inferiority of primary paclitaxel-coated balloons angioplasty to primary stenting for the treatment of de novo, non-complex lesions without vessel diameter restrictions. Patients who fulfill all the inclusion and exclusion criteria and have achieved a successful lesion pre-dilatation will be randomly assigned to the two arms in a 1:1 ratio. Protocol-guided DCB angioplasty and bailout stenting after unsatisfactory angioplasty are mandatory in the primary DCB angioplasty group. The second-generation sirolimus-eluting stent will be used as a bailout stent in the primary DCB angioplasty group and the treatment device in the primary stenting group. The primary endpoint is the incidence of Device-oriented Composite Endpoint (DoCE) within 24 months after randomization, including cardiac death, target vessel myocardial infarction, and clinically and physiologically indicated target lesion revascularization. DISCUSSION: The ongoing REC-CAGEFREE I trial is the first randomized trial with a clinical endpoint to assess the efficacy and safety of primary DCB angioplasty for the treatment of de novo, non-complex lesions without vessel diameter restrictions. If non-inferiority is shown, PCI with primary DCB angioplasty could be an alternative treatment option to primary stenting. TRIAL REGISTRATION: Registered on clinicaltrial.gov (NCT04561739).

INTRODUCTION: In-stent restenosis (ISR) is seen in up to 20% of cases and is the primary cause of percutaneous coronary intervention (PCI) failure. With the use of re-stenting with a drug-eluting stent (DES), plain old balloon angioplasty (BA) use is decreasing. We aim to compare the efficacy and safety profile of DES over BA in the management of ISR. METHODS: Electronic databases were searched to identify all randomized controlled trials (RCTs) comparing DES to BA for coronary ISR. The mantel-Haenszel method with a random effects model was used to calculate pooled risk ratios (RR). RESULTS: Four trials comprising 912 patients (543 in DES and 369 in the BA group) were included in the final study. The mean follow-up was 45 months. DES was found to be superior with a lower requirement of target vessel revascularization (TVR) (RR: 0.45, 95% CI: 0.31-0.64, p-value <0.0001), and target lesion revascularization (TLR) (RR: 0.59, 95%CI: 0.44-0.78, p-value 0.0002) compared to BA. However, all-cause mortality, cardiovascular mortality, incidence of myocardial infarction (MI), and target lesion thrombosis were not different between the two intervention arms. CONCLUSION: DES was found to be superior to BA for the management of coronary ISR with a reduction in the risk of TLR and TVR. No difference in mortality, risk of MI, or target lesion thrombosis was observed between the two interventions.

BACKGROUND: The treatment of in-stent restenosis (ISR) after drug-eluting stent (DES) implantation remains challenging in current clinical practice. AIMS: The study was conducted to investigate a novel biolimus-coated balloon (BCB) for the treatment of coronary DES-ISR compared with the best-investigated paclitaxel-coated balloon (PCB). METHODS: This was a prospective, multicentre, randomised, non-inferiority trial comparing a novel BCB with a clinically proven PCB for coronary DES-ISR. The primary endpoint was in-segment late lumen loss (LLL) at 9 months assessed by an independent core laboratory. Baseline and follow-up optical coherence tomography were performed in a prespecified subgroup of patients. RESULTS: A total of 280 patients at 17 centres were randomised to treatment with a BCB (n=140) versus a PCB (n=140). At 9 months, LLL in the BCB group was 0.23±0.37 mm compared to 0.25±0.35 mm in the PCB group; the mean difference between the groups was -0.02 (95% confidence interval [CI]: -0.12 to 0.07) mm; p-value for non-inferiority<0.0001. Similar clinical outcomes were also observed for both groups at 12 months. In the optical coherence tomography substudy, the neointimal area at 9 months was 2.32±1.04 mm2 in the BCB group compared to 2.37±0.93 mm2 in the PCB group; the mean difference between the groups was -0.09 (95% CI: -0.94 to 0.76) mm2; p=non-significant. CONCLUSIONS: This head-to-head comparison of a novel BCB shows similar angiographic outcomes in the treatment of coronary DES-ISR compared with a clinically proven PCB.
