The ultrathin strut biodegradable polymer sirolimus-eluting stent (Orsiro, O-SES) exhibits satisfactory clinical outcomes. However, no report to date has documented the intravascular status of artery repair after O-SES implantation. We examined 5 O-SES placed in 4 patients (age 65 ± 12 years, male 75%) presenting with stable angina pectoris due to de novo lesions in native coronary arteries. Coronary angioscopy was performed immediately after percutaneous coronary intervention and 1 year later. Angioscopic images were analyzed to determine the following: (1) dominant grade of neointimal coverage (NIC) over the stent; (2) maximum yellow plaque grade; and (3) existence of thrombus...

The use of cobalt-chromium everolimus-eluting stents (CoCr-EES) for ST-segment elevation myocardial infarction (STEMI) reduces the incidence of stent thrombosis compared with bare metal stents, and a substantial difference is apparent in the initial 2 weeks. However, vascular behavior during this early period remains unclear. This was a prospective study (MECHANISM-AMI-2W) to investigate early vascular responses in STEMI patients immediately after CoCr-EES implantation and at 2-week follow-up using frequency domain-optical coherence tomography (FD-OCT)...

We previously reported safety and usefulness of transradial iliac artery stenting using 6 Fr guiding sheath. However, radial artery occlusion was a major limitation of this procedure. We analyzed the safety and utility of slender transradial iliac artery stenting using a 4.5 Fr guiding sheath to prevent radial artery occlusion. We performed transradial iliac artery stenting in left radial artery, using a 4.5 Fr sheath incorporating a shaft length of 110 cm, for 34 lesions in 29 patients. Transradial intervention was attempted at the discretion of the operator...

The internal mammary artery (IMA) is the most durable conduit for bypassing the left anterior descending (LAD) coronary artery in patients undergoing coronary artery bypass graft surgery (CABG). However, little is known about how the IMA reacts histologically to stent implantation. From CVPath stent registry (1048 lesions, 614 cases), we obtained 4 stent lesions (2 bare metal stents, 2 drug-eluting stents) involving IMA grafts. The mean age of our patients was 63 years and the duration of stent implantation in the IMA ranged from 5 days to 5 years...

We aimed to compare the efficacy and safety of transcatheter aortic valve implantation (TAVI) using Edwards SAPIEN 3 (S3) valve and SAPIEN XT) in smaller anatomy. The new generation S3 TAVI device has been used worldwide; however, its efficacy and safety in smaller Asian anatomy remain unknown. Between February 2014 and March 2017, 166 consecutive patients (S3, 54; XT, 112) were treated with balloon-expandable TAVI in a single center and their outcomes were analyzed. Median patient age was 85 (range: 81-88) years and mean body surface area was 1...

The extension support guiding catheter has been used to perform complex percutaneous coronary intervention to increase back-up support for the guiding catheter or to ensure deep intubation for device delivery. However, because of its monorail design, advancement of the stent into the distal extension tubing segment is sometimes problematic. Although this problem is considered due to simple collision of the stent, operators have observed tangling between a monorail extension catheter and coronary guidewire in some patients...

Crossover stenting of femoral bifurcation raises the concern of jeopardizing the deep femoral artery (DFA) entry, thereby increasing future risk of limb-threatening ischemia and amputation. This retrospective multicenter study compared clinical outcomes of crossover stenting and non-crossover stenting for ostial superficial femoral artery (SFA) lesions. We reviewed 125 limbs in 103 patients with successful stent implantation for ostial SFA lesions and allocated them to two groups, based on whether the stent crossed over the DFA orifice (CO, n = 54) or not (NC, n = 71)...

We investigated the effect of low-density lipoprotein cholesterol (LDL-C) on the geometry of coronary bifurcation lesions. A total of 300 non-left main bifurcation lesions in 298 patients from J-REVERSE registry were classified according to statin treatment status at admission (NT, non-treated; ST, statin-treated) and were further subdivided based on LDL-C levels with a cutoff of 100 mg/dL (NT-high, n = 76 lesions; NT-low, n = 46; ST-high, n = 99 and ST-low, n = 79). In addition, a group with strict control of LDL-C (< 70 mg/dL) was defined (ST-SC; n = 19)...

We hypothesized that patients who had previous target-lesion revascularization (TLR) for DES restenosis in non-left main coronary artery (LMCA) lesions might have a higher risk for restenosis after subsequent DES implantation for a de novo unprotected LMCA lesion. Among 1809 patients enrolled in the Assessing Optimal Percutaneous Coronary Intervention for LMCA (AOI-LMCA) registry, which is a retrospective 6-centre registry of consecutive patients undergoing LMCA stenting in Japan, 251 patients with previous DES implantation for non-LMCA lesions were subdivided into the 2 groups with (N = 56) or without (N = 195) previous TLR in non-LMCA lesions...

Coronary chronic total occlusions (CTO) occur when there is complete, or near complete occlusion of a vessel, angiographically appreciated by the presence of a collateral circulation with late filling of the occluded vessel. With restoration of anterograde blood flow there is alteration in vascular wall stress which may influence distal vessel size. We sought to determine if the distal vessel size changes following revascularization of the CTO. We retrospectively reviewed patients who underwent successful CTO revascularization and who subsequently underwent repeat angiography...
