Optical coherence tomography —versus intravascular ultrasound-guided stent expansion in calcified lesions
AbstractOptical coherence tomography (OCT) has a higher resolution than intravascular ultrasound (IVUS) and enables a more precise evaluation of calcium severity. We investigated the impact of the imaging method (OCT versus IVUS) on stent expansion during intravascular imaging-guided percutaneous coronary intervention (PCI) in calcified lesions. In this single-center, retrospective, observational study, 145 lesions with moderate to severe calcification were divided into four groups: 40 IVUS-guided rotational atherectomy (RA), 38 IVUS-guided non-RA, 35 OCT-guided RA, and 32 OCT-guided non-RA. Lesions without pre-procedural ...

Prospective multicenter registry of hybrid coronary artery revascularization combined with non-saphenous vein graft surgical bypass and percutaneous coronary intervention using everolimus eluting metallic stents (PRIDE-METAL study)
This study aimed to investigate a 1-year clinical follow-up of a prospective multicenter registry of HCR combined with non-saphenous vein graft surgical bypass and PCI using everolimus-eluting metallic stents (the PRIDE-METAL study). From June 2016 to June 2018, a total of 54 patients with multivessel coronary disease from six Japanese institutes were enrolled in this study. The primary endpoint of the study was the occurrence of major adverse cardiovascular event (MACE; all-cause death, myocardial infarction, stroke, and repeat revascularization) at 1 year. Three patients declined before complete HCR, and two patients wer...

Balloon pulmonary angioplasty in chronic thromboembolic pulmonary hypertension
AbstractChronic thromboembolic pulmonary hypertension (CTEPH) is caused by chronic stenosis or obstruction of the pulmonary arteries due to thromboembolism. Although previous studies have shown untreated CTEPH has a poor prognosis, the establishment of gold-standard therapies including pulmonary endarterectomy, balloon pulmonary angioplasty (BPA), and medical therapy has improved hemodynamics and right ventricular function, leading to good long-term survival. BPA is an important therapy for patients with inoperable CTEPH, although the procedure is currently limited to specific institutions and operators. This review discus...

A serial optical frequency-domain imaging study of early and late vascular responses to bioresorbable-polymer sirolimus-eluting stents for the treatment of acute myocardial infarction and stable coronary artery disease patients: results of the MECHANISM-ULTIMASTER study
AbstractThe purpose of this study was to assess early and late vascular healing in response to bioresorbable-polymer sirolimus-eluting stents (BP-SESs) for the treatment of patients with ST-elevation myocardial infarction (STEMI) and stable coronary artery disease (CAD). A total of 106 patients with STEMI and 101 patients with stable-CAD were enrolled. Optical frequency-domain images were acquired at baseline, at 1- or 3-month follow-up, and at 12-month follow-up. In the STEMI and CAD cohorts, the percentage of uncovered struts (%US) was significantly and remarkably decreased during early two points and at 12-month (the ST...

Comparison of the cost in percutaneous coronary intervention between ST-segment elevation myocardial infarction vs. non-ST-segment elevation myocardial infarction
In conclusion, the total device cost for PCI was significantly higher in the culprit lesions of NSTEMI than in those of STEMI, whereas the procedure cost was significantly higher in the culprit lesions of STEMI than in those of NSTEMI. (Source: Cardiovascular Intervention and Therapeutics)

National survey of percutaneous coronary intervention during the COVID-19 pandemic in Japan: second report of the Japanese Association of Cardiovascular Intervention and Therapeutics
In conclusion, most institutions surveyed in Japan continued to perform primary PCI as usual for STEMI patients during the second and third waves of the COVID-19 pandemic. In addition, the COVID-19 screening tests were more frequently performed over time. (Source: Cardiovascular Intervention and Therapeutics)

Clinical implications of the invagination of an interwoven nitinol stent: a single-center retrospective analysis
AbstractStent invagination (SIV) sometimes occurs during interwoven nitinol stent (IWS) placement due to its complex deployment system. It may cause stent malapposition and reduce the minimum stent area. However, the clinical implications of SIV remain unclear. This retrospective single-center study sought to assess the clinical implications of IWS invagination in the femoropopliteal lesions in patients with peripheral arterial diseases. Thirty-two consecutive patients (23 men, mean age of 74  years, 34 limbs) with symptomatic femoropopliteal lesions who had received IWS implantation from January to July 2019 were enrolle...

Prasugrel switching from clopidogrel after percutaneous coronary intervention for acute coronary syndrome in Taiwanese patients: an analysis of safety and efficacy
AbstractThe recommended maintenance dose of prasugrel for East Asian populations (i.e., Japanese and Taiwanese) is 3.75  mg as part of dual antiplatelet therapy (DAPT) for the prevention of recurrent ischemia and stent thrombosis in acute coronary syndrome (ACS). This modified dosage regimen has been established in studies conducted in Japan; however, the efficacy and safety of switching from clopidogrel to prasugre l DAPT among Taiwanese patients remain to be explored. In this phase IV, multicenter, single-arm, open-label study, we evaluated the 4-week pharmacodynamic response, and the 48-week safety outcomes of prasugre...
