The purpose of this document is to make the output International Working Group for Intravascular Optical Coherence Tomography (IWG-IVOCT) Standardization and Validation available medical scientific communities, through a peer-reviewed publication, in interest improving diagnosis treatment patients with atherosclerosis, including coronary artery disease. optical coherence tomography (IVOCT) catheter-based modality that acquires images at resolution ∼10 μm, enabling visualization blood vessel...
Background:Stent underexpansion remains a concern as cause of drug-eluting stent (DES) failure. Although coronary calcification is considered to be contributing factor in underexpansion, previous intravascular ultrasound studies have failed demonstrate this relationship. We investigated whether expansion could predicted by assessed optical coherence tomography (OCT).Methods and Results:We enrolled 51 de novo native artery lesions treated single 2nd-generation DES (3 types). Prior deployment,...
The precise mechanism of tako-tsubo-like left ventricular (LV) dysfunction remains unclear, although recent studies have shown that activation sympathetic tone might be involved. However, local release catecholamines from cardiac efferent neurons in patients with LV poorly understood. purpose this study was to investigate evidence the hearts dysfunction.Five consecutive were studied. After confirming apical ballooning and a normal coronary angiogram, sampling blood for measurement plasma...
To investigate whether the ratio of early transmitral flow velocity (E) to diastolic mitral annular (E') predict prognosis in patients with non-valvular atrial fibrillation.230 fibrillation were enrolled and studied. According E/E' value, divided into groups lower (group A <or= 15) higher B > E/E'.During follow up (average 245 days), 21 (9.1%) deaths documented. All cause death (15/90 (16.7%) v 6/140 (4.3%)), cardiac (10 (11.1%) 2 (1.4%)) congestive heart failure (16 (17.8%) 8 (5.7%)) more...
Although left ventricular diastolic function has been shown to deteriorate with advancing age, its gender-specific change is unknown. The aim of this study was investigate age- and changes in tissue Doppler-derived index, E'.A total 1333 healthy individual without known heart disease or hypertension (mean 55 years; range, 10 89) were enrolled studied. Peak early mitral annular velocity (E') peak late (A') recorded measured. As an index the relaxation, E' used. filling pressure, E/E'...
Optical coherence tomography (OCT) can delineate calcified plaque without artefacts. The aim of this study was to evaluate the ability OCT quantify in ex vivo human coronary arteries.Ninety-one segments from 33 consecutive cadavers were examined. By intravascular ultrasound (IVUS), 32 superficial plaques, defined as leading edge acoustic shadowing appears within most shallow 50% plus media thickness, selected and compared with corresponding histological examinations. area calcification...
Background: The clinical impact of stent edge dissection, tissue protrusion, and incomplete apposition (ISA) after implantation, detectable only on optical coherence tomography (OCT), is still unknown because the natural course has not been investigated. Methods Results: All consecutive patients with angina pectoris in whom both intravascular ultrasound (IVUS) OCT were performed immediately stenting at follow-up included present study. history OCT-detected ISA during was A total 36 39...
Previous studies showed that patients with takotsubo cardiomyopathy had a higher long-term mortality rate than the general population and incidence of in-hospital complications was in without right ventricular (RV) involvement. This study performed to investigate prognostic impact RV involvement cardiomyopathy. The clinical data 113 (72.7 ± 11.4 years old, 84 females) were studied retrospectively. divided into two groups according presence (biventricular group, n = 21, 18.6%) or absence...
Abstract Takotsubo syndrome (TTS) is a complex and still poorly recognized heart disease with wide spectrum of possible clinical presentations. Despite its reversibility, it associated serious adverse in-hospital events high complication rates during follow-up. Multimodality imaging helpful for establishing the diagnosis, guiding therapy, stratifying prognosis TTS patients in both acute post-acute phase. Echocardiography plays key role, particularly care setting, allowing assessment left...
With aging of the population, economic burden associated with heart failure (HF) is expected to increase. However, little known about hospitalization costs HF in Japan. Methods and Results: In this cross-sectional study, using data from The Japanese Registry All Cardiac Vascular Diseases (JROAD) JROAD-Diagnosis Procedure Combination databases between 2012 2014, we evaluated for acute cardiovascular diseases (CVDs), including HF. A total $1,187 million/year (44% CVDs) was spent on patients We...
