Clinical outcomes for intracoronary imaging strategies at different medical facilities in Japanese patients with coronary artery disease: the SAKURA imaging PCI Registry
AbstractThe relationships between intracoronary imaging modalities and outcomes among Japanese patients with coronary artery disease (CAD) based on the type of medical facility providing outpatient care remain unclear. In this multicenter prospective study (SAKURA PCI Registry), we aimed to investigate the clinical outcomes of patients with CAD who underwent percutaneous coronary intervention (PCI) between April 2015 and December 2018. In this registry, we investigated differences in patient characteristics, intracoronary imaging modalities, and clinical outcomes between two types of medical facilities. Of the 414 patients...

Porphyromonas gingivalis and left atrial appendage spontaneous echo contrast in atrial fibrillation ablation candidates
AbstractAtrial fibrillation (AF) is associated with a fivefold risk of stroke and thrombotic embolism, which are usually derived from the left atrial appendage (LAA). Spontaneous echo contrast (SEC) is known as a risk factor for thrombosis.Porphyromonas gingivalis (P.gingivalis) has some prothrombotic effects and plays a key role in periodontitis and oral-systemic disease connection. We aimed to clarify the relationship betweenP. gingivalis and LAA SEC among AF patients. A total of 569 AF ablation candidates were enrolled in the present study. LAA SEC was categorized into nondense SEC and dense SEC based on transesophageal...

Computed tomography perfusion in patients of stroke with left ventricular assist device
AbstractLeft ventricular assist devices (LVAD) are widely applied for patients with severe heart failure as a bridge to heart transplantation as well as destination therapy. Patients with implanted LVAD have an increased risk of cerebral thrombosis and computed tomographic perfusion (CTP) has the potential to be performed for early diagnosis and treatment of acute ischemic stroke (AIS), including interventional thrombectomy. Here, we report our series of CTP examination in patients having suspected AIS after LVAD implantation. We retrospectively investigated 33 contrast-enhanced CTPs from January 2017 to December 2018 whic...

Cilostazol-based triple versus potent P2Y12 inhibitor-based dual antiplatelet therapy in patients with acute myocardial infarction undergoing percutaneous coronary intervention
AbstractAlthough potent P2Y12 inhibitor-based dual antiplatelet therapy (DAPT) has replaced clopidogrel-based therapy as the standard treatment in patients with acute myocardial infarction (AMI), there is a concern about the risk of bleeding in East Asian patients. We compared the efficacy and safety of cilostazol-based triple antiplatelet therapy (TAT) with potent P2Y12 inhibitor-based DAPT in Korean patients. A total of 4152 AMI patients who underwent percutaneous coronary intervention (PCI) in the Korea Acute Myocardial Infarction Registry were analyzed retrospectively. Patients were divided into two groups: the TAT gro...

Efficacy and safety of left atrial appendage closure in non-valvular atrial fibrillation in patients over 75  years
AbstractPercutaneous left atrial appendage closure (LAAC) may decrease risks of stroke and bleeding in elderly patients with non-valvular atrial fibrillation (NVAF), but it is still lacking of evidence. The present study aimed at evaluating the efficacy and safety of LAAC in patients with NVAF over 75  years. 351 patients with NVAF who underwent LAAC were retrospectively analyzed on the LAAC procedure characteristics and the clinical follow-up according to age (age ≥ 75 years or <  75 years). Out of the 351 patients, LAA were successfully closed in 347 patients (98.9%), including 341 with Watchman (WM) devi...

Major cardiovascular and bleeding events with long-term use of aspirin in patients with prior cardiovascular diseases: 1-year follow-up results from the Management of Aspirin-induced Gastrointestinal Complications (MAGIC) study
This study was conducted to clarify CV and bleeding events in Japanese aspirin users with a history of CV diseases. This study was a prospective, nationwide, multicenter cooperative registry of Japanese patients with CV diseases at risk of thromboembolism who were taking aspirin (75–325 mg) for at least 1 year. We observed major CV and bleeding events during follow-up. Patients with history of ischemic stroke (IS), transient ischemic attack (TIA), coronary artery disease (CAD), atrial fibrillation (AF), and venous thromboembolism (VTE) were included and analyzed in this sutdy. CV events included IS, TIA, CAD, CV death,...

Left atrial remodeling index is a feasible predictor of poor prognosis in patients with acute ischemic stroke
This study aimed to elucidate whether combined assessment of LA functional and structural remodeling can predict LAA dysfunction and recurrent cerebrovascular events in patients with acute ischemic stroke. We performed transthoracic and transesophageal echocardiography in 196 patients within 7  days after acute ischemic stroke. Peak systolic LA strain was evaluated using 2D speckle tracking imaging. We defined the ratio of LA peak systolic strain to LA volume index (LAVI) as the LA remodeling index (LARI). All patients were prospectively followed for recurrent cerebrovascular events. We divided patients into four groups a...

Predictors of thrombus formation after percutaneous left atrial appendage closure using the WATCHMAN device
AbstractPercutaneous left atrial appendage (LAA) closure using the WATCHMAN device is a novel option for prevention of stroke associated with atrial fibrillation. However, device-related thrombus (DRT) formation is a concern after WATCHMAN implantation and the predictors of DRT still remain unclear. We aimed to clarify the predictors of DRT after WATCHMAN implantation by analyzing 78 patients (50 males, 72  ± 8 years, average CHA2DS2-VASc score of 4.3 + 1.8) who had undergone WATCHMAN implantation. WATCHMAN was successfully implanted in all patients and four (5%) developed DRT. Patients with DRT were more often fe...

Bioresorbable vascular scaffolds in coronary chronic total occlusions revascularization: safety assessment related to struts coverage and apposition in 6-month OCT follow-up
AbstractBeneficial properties of bioresorbable vascular scaffolds (BVS) regarding to vasomotility restoration and no caging of the vessel make them attractive devices in chronic total occlusions (CTO) revascularization. However, more evidence is needed attending to their use in this specific setting. We aim to determine feasibility and safety of BVS use in CTO revascularization attending to struts coverage and apposition, as well as re-stenosis and stent thrombosis (ST) rates. 29 BVS were deployed in 9 CTO lesions revascularization (mean J-CTO score ≥3) with an acute procedural success rate of 100%. Clinical and angiogra...

Stroke prevention following modified endoscopic ablation and appendectomy for atrial fibrillation
We reported the results of stroke prevention following modified endoscopic procedure for atrial fibrillation. 82 patients underwent modified endoscopic procedure for atrial fibrillation (AF), in whom 47 had paroxysmal, 28 had persistent, and 7 had long-standing atrial fibrillation. CHA2DS2VASC median score was 3 (range from 0 to 8). The procedure was performed on the beating heart, through 3 ports on the left chest wall. Pulmonary vein isolation and ablation of the left atrium were achieved by bipolar radiofrequency ablation. Left atrial appendage (LAA) was excluded by stapler. Brain CT, cardiac CT and 24-h Holter monitori...
