Numasawa Y, Sawano M, Ishii H, Kohsaka S, Kikuta Y, Matoba T, Amano T, Kozuma K. One-year outcomes of patients undergoing percutaneous coronary intervention with the revived directional coronary atherectomy catheter: Insights from the J-PCI OUTCOME registry. Catheter Cardiovasc Interv 2023; 102:1229-1237. [PMID: 37943854 DOI: 10.1002/ccd.30895] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Revised: 09/20/2023] [Accepted: 10/17/2023] [Indexed: 11/12/2023]
Abstract
OBJECTIVES We sought to investigate the 1-year outcomes, including all-cause and cardiovascular mortality, major adverse cardiovascular events (MACEs), and major bleeding, of patients undergoing percutaneous coronary intervention (PCI) with or without the revived directional coronary atherectomy (DCA) catheter in a Japanese nationwide registry. BACKGROUND Clinical data regarding the midterm outcomes of patients undergoing PCI with DCA are scarce in contemporary real-world practice. METHODS We analyzed the data of 74,764 patients who underwent PCI at 179 hospitals from January 2017 to December 2018. The baseline characteristics and 1-year outcomes of patients with stable coronary artery disease or unstable angina who underwent PCI with or without DCA were assessed. RESULTS Overall, 431 patients (0.6%) underwent PCI with DCA. Patients in the DCA group were younger and predominantly male, with fewer comorbidities than patients in the non-DCA group. Stentless PCI with DCA following additional drug-coated balloon (DCB) angioplasty was the dominant strategy in the DCA group (43.6%). One-year outcomes, including all-cause mortality (1.2% in the DCA group vs. 2.5% in the non-DCA group, respectively, p = 0.075), cardiovascular death (0.9% vs. 1.0%, p = 0.69), MACEs (1.9% vs. 1.8%, p = 0.96), and nonfatal major bleeding requiring readmission (1.2% vs. 1.4%, p = 0.62), were comparable between the two groups. In the DCA group, 1-year outcomes were comparable, regardless of whether the stent or DCB was used. CONCLUSIONS One-year clinical outcomes after PCI with DCA in patients with stable coronary artery disease or unstable angina are acceptable, regardless of stent use.

Abstract
OBJECTIVES We sought to provide clinical insights on the usage rate, indications, and in-hospital outcomes of the revived directional coronary atherectomy (DCA) catheter (Atherocut™) in a Japanese nationwide percutaneous coronary intervention (PCI) registry. BACKGROUND Debulking devices such as the revived DCA catheter have become increasingly important in the era of complex PCI. However, little is known about PCI outcomes using a novel DCA catheter in contemporary real-world practice. METHODS We analyzed 188,324 patients who underwent PCI in 1112 hospitals from January to December 2018. Baseline characteristics and in-hospital outcomes of patients with stable coronary artery disease or unstable angina who underwent PCI with or without the DCA were analyzed. RESULTS Overall, 1696 patients (0.9%) underwent PCI with the DCA during the study period, predominantly for left main trunk or proximal left anterior descending artery lesions under a transfemoral approach. Patients in the DCA group were younger and had fewer comorbidities such as hypertension, diabetes mellitus, and chronic kidney disease than patients in the non-DCA group. Stentless PCI using the DCA with drug-coated balloon angioplasty was a preferred treatment strategy in the DCA group (50.0%). Predefined in-hospital adverse outcomes, including mortality (0.2% vs. 0.3%, p = 0.446) and periprocedural complications (1.8% vs. 1.7%, p = 0.697), were comparable between the two groups, whereas the fluoroscopy time was longer and the total contrast volume was higher in the DCA group. CONCLUSIONS In Japan, PCI using the revived DCA catheter is safely performed with low complication rates in patients with stable coronary artery disease or unstable angina.

Clin Med Insights Case Rep 2022; 15:11795476221075497. [PMID: 35295408 PMCID: PMC8918956 DOI: 10.1177/11795476221075497] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Accepted: 12/23/2021] [Indexed: 11/15/2022] Open
Abstract
Background: Directional coronary atherectomy (DCA) revived in Japan since 2014. DCA is a special device to remove the atherosclerotic plaque of coronary artery in percutaneous coronary intervention (PCI). However, DCA procedure is recommended to perform by 8Fr system, which is one of the limitations of DCA. Case Series: Since transradial approach is the main access route for PCI, we considered how to perform DCA by TRA. The external diameter of 8Fr guiding catheter (GC) and 6Fr sheath are 2.70 and 2.67 mm. Then, if 6Fr sheath can be inserted without any resistance, 8Fr GC is considered to be insertable. We performed 5 cases of DCA by the transradial 8Fr sheathless GC approach, all cases were successful without discomfort associated with insertion and removal of the 8Fr GC. Conclusion: DCA by the transradial 8Fr sheathless GC approach might be one of options to avoid bleeding complication and serve more comfortable treatment for the patients.

Impact of directional coronary atherectomy followed by drug-coated balloon strategy to avoid the complex stenting for bifurcation lesions. Heart Vessels 2022; 37:919-930. [PMID: 34981167 DOI: 10.1007/s00380-021-02000-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Accepted: 11/26/2021] [Indexed: 01/25/2023]
Abstract
Although the simple single stenting rather than complex double stenting is recommended on percutaneous coronary intervention (PCI) for bifurcation lesions, double stenting cannot always be avoided. We investigated the impact of directional coronary atherectomy (DCA), followed by drug-coated balloon (DCB) treatment to reduce the number of stents and avoid complex stenting in PCI for bifurcation lesions and short-term patency. DCA treatment without stents was attempted for 27 bifurcation lesions in 25 patients, of those, 26 bifurcation lesions in 24 patients were successfully treated and 3-month follow-up angiography and optical coherence tomography (OCT) were performed. Sixteen lesions (59.3%) were related to left main trunk distal bifurcations, and 7 (25.9%) were true bifurcation lesions. Among the true bifurcation lesions, 4 lesions (57.1%) needed 1 stent, and the other 3 lesions (42.9%) needed no stents. Among the non-true bifurcation lesions, 1 lesion (5.0%) needed bailout stent and other lesions (95.0%) needed no stents. According to DCA followed by DCB treatment, the angiographic mean diameter stenosis improved from 65.5 ± 15.0% to 7.8 ± 9.8%, and the mean plaque area in intravascular ultrasound improved from 80.4 ± 10.5% to 39.0 ± 11.5%, respectively. Angiographic and OCT late lumen loss values were 0.2 ± 0.6 mm and 1.4 ± 1.9 mm, respectively. No patient had in-hospital major adverse cardiac events (MACE) and 3-month MACE. In conclusion, compared with standard provisional side branch stenting strategy, DCA followed by DCB treatment might reduce the number of stents, avoid complex stenting for major bifurcation lesions and provide good short-term outcomes.

Abstract
AIMS To evaluate the vascular response after directional coronary atherectomy (DCA) for left main (LM) bifurcation lesion. METHODS This study was a retrospective, single-center study enrolling 31 patients who underwent stentless therapy using DCA followed by drug-coated balloon (DCB) angioplasty for LM bifurcation lesion. We compared intravascular ultrasound (IVUS) findings before and after DCA. RESULTS After DCA, the lumen and vessel areas significantly increased, whereas the plaque area (PA) and %PA were significantly reduced. When the lesions were divided into small vessel and large vessel groups using the median value of the vessel area, the maximum balloon pressure of the DCA catheter was greater in the large vessel group. Changes in the lumen and vessel areas were also significantly greater in the large vessel group. On the other hand, the changes in PA and %PA were similar between groups. CONCLUSIONS The main vascular responses associated with lumen enlargement after DCA were plaque reduction and vessel expansion. Contribution of vessel expansion to lumen enlargement was larger than the effect of plaque reduction in large vessel lesions.

Abstract
OBJECTIVES We sought to evaluate the efficacy of plaque debulking by directional coronary atherectomy (DCA) prior to second-generation drug-eluting stent (DES) implantation for bifurcated coronary lesions. BACKGROUND Percutaneous coronary intervention (PCI) for bifurcated lesions still remains complex and challenging in terms of restenosis or stent thrombosis regardless of whether simple or complex stenting is used. METHODS Patients with bifurcated lesions were enrolled in this prospective multicenter registry. Pre-second-generation DES plaque debulking with a novel DCA catheter (ATHEROCUT®, Nipro Co., Osaka, Japan) was conducted. All patients were scheduled to perform a follow up angiography (9-12 month coronary angiography or coronary computed tomography). The primary end point was target vessel failure (TVF) at follow up. Secondary end points were procedure-related events and major adverse cardiac events at 1 year. RESULTS A total of 77 patients with bifurcated lesions were enrolled. PCI with DCA was performed successfully in all cases without any major procedure-related event and only one case required complex stenting. The TVF rate at 9-12 month follow up was 3.9% (3 of 77) and those were all associated with revascularization of the target vessel. Restenosis was only observed at the ostium of the main-branch in three cases. No death, coronary artery bypass grafting, or myocardial infarction were reported for any patients within the first year. CONCLUSION DCA before second-generation DES implantation can possibly avoid complex stenting and provide a good mid-term outcome in patients with bifurcated lesions.

Abstract
OBJECTIVES To evaluate the efficacy and safety of additional drug-coated balloon (DCB) angioplasty after directional coronary atherectomy (DCA) for coronary bifurcation lesions. BACKGROUND The optimal therapy for bifurcation lesions has not been established, even in the drug-eluting stent era. DCA possibly prevents plaque and carina shift in bifurcation lesions by plaque debulking; however, the efficacy of combined DCA and DCB (DCA/DCB) for bifurcation lesions remains unclear. METHODS This multicenter registry retrospectively recruited patients with bifurcation lesions who underwent DCA/DCB and follow-up angiogram at 6-15 months. The primary endpoint was the 12-month target vessel failure (TVF) rate. The secondary endpoints were procedure-related major complications, major cardiovascular events at 12 months, restenosis at 12 months, target lesion revascularization (TLR) at 12 months, and target vessel revascularization (TVR) at 12 months. RESULTS We enrolled 129 patients from 16 Japanese centers. One hundred and four lesions (80.6%) were located around the left main trunk bifurcations. No side branch compromise was found intraoperatively. Restenosis was observed in three patients (2.3%) at 12 months. TLR occurred in four patients (3.1%): 3 (2.3%) in the main vessel and 1 (0.8%) in the ostium of the side branch at 12 months. TVF incidence at 12 months was slightly higher in 14 patients (10.9%), and only two patients (1.6%) had symptomatic TVR. One patient (0.8%) had non-target vessel-related myocardial infarction. CONCLUSIONS Our data suggested that DCA/DCB provided good clinical outcomes and minimal side branch damage and could be an optimal non-stent percutaneous coronary intervention strategy for bifurcation lesions.

In vivo tissue characterization of human atherosclerotic plaques by optical coherence tomography: A directional coronary atherectomy study with histopathologic confirmation. Int J Cardiol 2018; 268:1-10.

Abstract
BACKGROUND The histopathological validation of optical coherence tomography (OCT) in visualizing atherosclerotic plaques has been reported only in ex vivo studies. We sought to evaluate the accuracy of OCT in tissue characterization in vivo. METHODS AND RESULTS A total of 25 patients with stable angina pectoris who underwent directional coronary atherectomy (DCA) were included in the investigation, whereby OCT was performed before and after a single debulking. The debulked region was determined on OCT and classified into fibrous tissue, lipid, calcification, thrombus, and macrophage accumulation, which were compared with histology. Changes in OCT signal intensity in the deeper intimal region after DCA were also visually evaluated. Fibrous tissues were detected in all cases, while thrombus was identified only in 1 case, by both OCT and histology. The sensitivity, specificity, positive and negative predictive values, and predictive accuracy for lipid detection by OCT were 88.9%, 75.0%, 66.7%, 92.3%, and 80.0%; those for calcification were 50.0%, 100%, 100%, 91.3%, and 92.0%; and those for macrophage accumulation were 85.7%, 88.9%, 75.0%, 94.1%, and 88.0%, respectively. The false positive diagnoses for lipid were mostly attributed to the extracellular matrix accumulation containing less collagen. The false negative diagnoses for calcification were explained by the presence of lipid around the calcification. The OCT signal intensity in the deeper intimal region substantially increased after DCA in all cases. CONCLUSIONS The current study showed excellent predictive accuracy of in vivo OCT in tissue characterization, whereas the limitations of OCT were highlighted by an over-detection of lipid, under-detection of calcification, and underestimation of the deeper intimal matrix.

Peeled Guidewire Coating with Debulked Plaque Obtained by Directional Coronary Atherectomy. Case Rep Cardiol 2017; 2017:2397183.

Abstract
Percutaneous directional coronary atherectomy (DCA) is a plaque debulking method performed in Japan, and recently a renewed DCA device has been launched. We present a case with a tight left anterior descending lesion undergoing percutaneous coronary intervention with application of DCA. After several sessions of DCA, white plaques accompanied by green, stringed materials were obtained from the device; some materials were considerably long (approximately 15 mm in length). A drug-eluting stent was subsequently implanted, and the procedure was completed successfully without any complications. The extracted plaques and artificial materials were pathologically examined, and no inflammatory changes were detected on plaques adjacent to the material. Assessing pathological findings and structure of the DCA catheter, the obtained artificial materials were considered as peeled guidewire, possibly resulting from the friction between the guidewire and metallic bearing in the housing of DCA catheter. Of note, this phenomenon has been recognized even in other DCA cases in which guidewires of the other kind are used. We report this phenomenon for the first time, warning of theoretically possible distal embolization of artificial materials caused by any debulking devices.
