Earlier studies have often required the absence of obstructive coronary artery disease (CAD) as criteria. However, it is probable that patients with tako-tsubo cardiomyopathy an incidental CAD because most are elderly. We assessed prevalence CAD.We reviewed angiograms 97 Japanese cardiomyopathy. A wrapped left anterior descending (LAD) was defined a LAD perfused at least one-quarter inferior wall ventricle in 30 degrees right oblique projection.Ten (10%) had definitively greater than 75%...
Abstract Aims We aimed to identify three-dimensional echocardiographic predictors of tricuspid regurgitation (TR) regression in patients with functional TR moderate or greater severity undergoing mitral valve transcatheter edge-to-edge repair optimize patient selection and improve clinical outcomes. Methods Results This retrospective study analyzed 61 (mean age 81.3±7.6 years; 55.7% males) who underwent repair. Two-dimensional transthoracic echocardiography was performed pre- 1-month...
Recent studies have demonstrated that stress-induced Tako-tsubo cardiomyopathy is likely to occur in elderly female patients.The purpose of this study was evaluate gender differences the clinical characteristics patients with cardiomyopathy.This consisted 102 cardiomyopathy. It characterized by akinesia/hypokinesia mid-to-distal portion left ventricular chamber, normokinesia/hyperkinesia basal an ejection fraction less than 50% on transthoracic echocardiography.There were 13 male and 89...
The aim of this study was to clarify the clinical outcomes patients with atrial functional mitral regurgitation (FMR) who underwent MitraClip procedure compared those conventional FMR and sinus rhythm (SR).
In 2008, the Guidelines for diagnosis and treatment of patients with vasospastic angina (coronary spastic angina) [[1]JCS Joint Working Group (JCS 2008): digest version.Circ J. 2010; 74: 1745-1762Crossref PubMed Scopus (231) Google Scholar] were developed by Japanese Circulation Society, revised version was published in 2013 [[2]JCS 2013): 2014; 78: 2779-2801Crossref Scholar]. Since then, new findings from various fields such as coronary microvascular dysfunction (CMD), biomarkers, imaging,...
The objective was to investigate the outcomes of concomitant venoarterial extracorporeal membrane oxygenation (ECMO) and left ventricular unloading with Impella (ECPELLA) compared ECMO alone treat patients affected by cardiogenic shock. Data from needing mechanical circulatory support 4 international centers were analyzed. Of 438 included, ECPELLA adopted in 319 (72.8%) 119 (27.2%) patients, respectively. Propensity score matching analysis identified 95 pairs. In matched cohort, 30-day...
Artificial intelligence quantitative CT (AI-QCT) determines coronary plaque morphology with high efficiency and accuracy. Yet, its performance to quantify lipid-rich remains unclear. This study investigated the of AI-QCT for detection low-density noncalcified (LD-NCP) using near-infrared spectroscopy-intravascular ultrasound (NIRS-IVUS).The INVICTUS Registry is a multi-center registry enrolling patients undergoing clinically indicated angiography IVUS, NIRS-IVUS, or optical coherence...
Postoperative atrial fibrillation (POAF) is a common complication of cardiac surgery and results in increased health-care utilization. This study identified new transthoracic echocardiographic predictors POAF using an index the total conduction time derived on tissue Doppler imaging (PA-TDI duration) patients undergoing off-pump coronary artery bypass grafting (OPCAB). A 88 isolated OPCAB were enrolled. They examined preoperatively echocardiography with evaluations monitored postoperatively...
Background: The serum lipoprotein (a) [Lp(a)] level is genetically determined and remains consistent during a person's life. Previous cohort studies have reported that subjects with high Lp(a) are at risk of cardiac events. Methods Results: This study consisted 410 patients who underwent primary percutaneous coronary intervention within 24h the onset acute myocardial infarction (AMI). was measured 1 week after AMI were divided into 2 groups based: group (>40mg/dl, n=95) low (≤40mg/dl,...
The present study was undertaken to assess the effect of L-glutamate on extended preservation heart ex vivo added a hypothermic preservative solution. Ten sheep hearts were removed after application cold crystalloid potassium cardioplegia. immersed in iced normal saline and right ventricular left intraventricular balloons connected transducers measure compliance. Thermistor probes placed interventricular septum. mounted retrograde perfusion apparatus via cannula brachiocephalic trunk an...
Abstract Aims We sought to find the morphological mechanisms of recurrent mitral regurgitation (MR) after MitraClip procedure using 3D transoesophageal echocardiography (TOE). Methods and results Of 478 consecutive patients treated with initial procedure, 41 who underwent repeat valve (MV) transcatheter or surgical intervention for MR were retrospectively reviewed. Using 3D-TOE, we investigated changes MV leading intervention. Aetiology at index was primary in 24 (59%) secondary 17 (41%)...
Abstract Introduction The aim of the present study was to investigate impact time interval from collapse return spontaneous circulation (CPA-ROSC) in cardiac arrest patients and types who will benefit therapeutic hypothermia. Methods Four hundred witnessed adult comatose survivors out-of-hospital etiology were enrolled study. favorable neurological outcome defined as category 1 or 2 on five-point Pittsburgh cerebral performance scale at hospital discharge. A matching process based propensity...
It is clinically important to recognize how the underweight or obese affects electrocardiogram (ECG). We assessed effects of body mass index (BMI) on QRS axis R-wave heights. From daily outpatient electrocardiograms with sinus rhythm, 203 were selected. The patients classified into four groups: (< 18.5 kg/m2), normal weight (18.5–24.9 overweight (25–29.9 kg/m2) and (≥ 30 kg/m2). With increasing BMI, shifted rightward leftward. There was a significant inverse correlation between BMI (r = −...
Objectives Mitral valve (MV) clip procedure requires interatrial trans-septal puncture to access the left atrium (LA). Iatrogenic atrial septal defect (iASD) is not uncommon and may remain for a while. However, haemodynamic echocardiographic determinants of persistent iASD are well investigated. We sought find after MV clip. Methods A total 131 patients with grades 3 4+ mitral regurgitation who underwent MitraClip completed invasive measurement, baseline, 1 month approximately 12 months...
