The PRASFIT-ACS study showed the antiplatelet effect 2-4 h after prasugrel loading. However, there is little information about the antiplatelet effect <2 h after prasugrel loading dose, especially in patients with acute coronary syndrome (ACS). There had not been any comparison between ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation ACS (NSTE-ACS). Fifty patients with ACS (15 with STEMI and 35 with NSTE-ACS) were enrolled. They received a 20-mg prasugrel loading dose followed by a maintenance dose of 3...

There is a growing interest in the optimizing care of acute coronary syndrome (ACS) in young patients, largely owing to their potential for longer life expectancy. Herein, we aimed to investigate the clinical characteristics and outcome of young ACS patients (e.g. under 60 year old) from a Japanese multicenter percutaneous coronary intervention (PCI) registry (KiCS-PCI). KiCS-PCI registered consecutive ACS patients from 15 institutions, and 1560 (24.0%) out of 6499 ACS-related PCI involved patients aged <60 years...

Transcatheter aortic valve implantation (TAVI) is an alternative therapeutic option for severe aortic stenosis. Aortic regurgitation (AR) is commonly observed after TAVI and increases the mortality rate. We hypothesized that the influence of significant AR, defined as that more severe than mild AR, on survival rate after TAVI might differ according to the baseline left ventricular ejection fraction (LVEF) and N-terminal pro-B-type natriuretic peptide (NT-pro BNP) level. We categorized 856 patients who underwent transfemoral TAVI into 2 groups according to their baseline LVEF (<40 and ≥40%) and NT-pro BNP levels (≤5000 and >5000 pg/mL)...

OCT is widely used for accurate coronary stent sizing; however, the impact of coronary tortuosity or guide wire weight on the accuracy of OCT in assessing coronary dimensions is not known. This study sought to determine whether guide wire properties impact on coronary diameter and length estimation by optical coherence tomography (OCT) in tortuous segments of coronary artery. OCT coronary diameters were determined in selected patients with tortuous arteries before and after removal of a supportive guide wire to obtain unobscured images...

Contrast-induced acute kidney injury (CI-AKI) is a common event after percutaneous coronary intervention (PCI). Presently, the main strategy to avoid CI-AKI lies in saline hydration, since to date none pharmacologic prophylaxis proved beneficial. Our aim was to determine if a low complexity mortality risk model is able to predict CI-AKI in patients undergoing PCI after ST elevation myocardial infarction (STEMI). We have included patients with STEMI submitted to primary PCI in a tertiary hospital. The definition of CI-AKI was a raise of 0...

Transcatheter aortic valve implantation is an established alternative and less invasive procedure to replace heart valves in symptomatic aortic stenosis patients; however, severe, life-threatening complications still exist. Coronary artery occlusion is a primary complication. We report a case of left main coronary artery occlusion after transcatheter aortic valve replacement, which was ameliorated using a double stent implantation technique.

We conducted propensity-score-matched comparisons of midterm angiographic follow-up outcomes of sirolimus- versus everolimus-eluting stents (SES, EES) after elective placements for de novo coronary stenosis in small vessels (SV) in patients with diabetes mellitus (DM), because the angiographic efficacy of EES over SES for those cohorts remained unclear. The study was a non-randomized, retrospective, lesion-based, multicenter study, examining lesions followed up angiographically within 550 days, extracted from the unified database of 6 institutes...

Prasugrel is a third-generation thienopyridine that achieves potent platelet inhibition with less pharmacological variability than other thienopyridines. However, clinical experience suggests that prasugrel may be associated with a higher risk of de novo and recurrent bleeding events compared with clopidogrel in Japanese patients undergoing percutaneous coronary intervention (PCI). In this review, we evaluate the risk of bleeding in Japanese patients treated with prasugrel at the doses (loading/maintenance doses: 20/3...

We aimed to clarify the relationships between angiographic lesion characteristics and values of fractional flow reserve (FFR) on intermediate coronary artery stenosis. The clinical meaning and assessment for "visual-functional mismatches," including regular-mismatches [defined as angiographic percent diameter stenosis (%DS) ≥50 % and FFR >0.80] and reverse-mismatches (defined as angiographic %DS <50 %, FFR ≤0.80) remains unresolved in contemporary practice. We retrospectively enrolled 140 consecutive patients who underwent coronary angiography and FFR measurement...

Few socioeconomic studies have so far reported on revascularization for stable ischemic heart disease in Japan. This study aimed to validate the sensitivity of the health-related quality of life (HRQOL) scale for determining the pathology and medical technology to be used and to validate the application of a cost-utility analysis model. We studied 32 patients who had undergone percutaneous coronary intervention (PCI) (mean age 67.9 ± 7.3 years). For HRQOL, utility and quality of life (QOL) were examined using the EuroQol 5 Dimension (EQ-5D) and EuroQol Visual Analogue Scale (EQ-VAS), respectively...

We present a safe and effective method of transcatheter aortic valve implantation using an artificial graft anastomosed to the common iliac artery. A 10-mm woven polyethylene terephthalate graft is anastomosed to the common iliac artery. A guide wire and an expandable sheath are inserted through the graft, and bleeding from the puncture site is controlled by three tourniquets circled around the graft. Using this technique, we can bring the graft outside of the retroperitoneal space, allowing easy manipulation of the guide-wire and sheath, unimpeded by the constraints of the deep and narrow retroperitoneal space...

A 79-year-old man developed severe bilateral ischemic symptoms in the lower limbs. Chest-abdominal-pelvic contrast computed tomography (CT) showed acute occlusion involving the abdominal aorta, and endovascular therapy (EVT) was used as emergency treatment. Two self-expandable stents placed in the thrombus area resulted in restoration of blood flow to the lower limbs, despite limited stent expansion, and movement of these limbs. Follow-up CT showed good stent expansion. The patient had a favorable recovery without additional surgery...

This report describes a case of subacute stent thrombosis (SAT) after drug-coated balloon (DCB). A 79-year-old male was investigated for stable angina. An in-stent restenosis (ISR) lesion was detected by coronary angiography. A skin reaction related to the anti-platelet agent thienopyridine was also observed at this time. Therefore, DCB was used to treat the ISR lesion under single anti-platelet therapy (aspirin). However, 3 days after percutaneous coronary intervention, SAT occurred. OCT did not reveal the underlying cause of SAT...

A 64-year-old male with intermittent claudication due to long chronic total occlusion of external iliac artery was successfully treated with a bi-directional approach. The retrograde guidewire was inserted into the ipsilateral internal iliac artery to the distal femoral artery through a collateral channel. The procedure was performed with a single guiding catheter through a single puncture of the left radial artery. Avoid puncture of the femoral artery may be less invasive with fewer bleeding complications.

We experienced a case in which a previously deployed stent was extracted during a percutaneous coronary intervention to the stent-jailed side branch by the transradial approach. The stent was dislodged in the radial artery, was fully expanded, and partially deformed, making it difficult to retrieve via the radial sheath. Using a handmade flared guiding catheter, the expanded deformed stent was successfully retrieved via a 6-Fr radial sheath.

The patient was a 91-year-old woman presenting with severe aortic valve stenosis. Pre-procedural computed tomography scan revealed a 45-mm abdominal aortic aneurysm (AAA). Transfemoral transcatheter aortic valve implantation (TF-TAVI) was performed after endovascular aortic repair (EVAR) of the AAA. The 23-mm Edwards Sapien XT system passed through the aortic stent graft smoothly. This is the first case report showing that successful TF-TAVI can be performed through a prior abdominal aortic stent graft. TF-TAVI after EVAR of AAA is a feasible option for patients with extremely poor access...
