Vessel-level physiological data derived from pressure wire measurements are one of the important determinant factors in optimal revascularisation strategy for patients with multivessel disease (MVD). However, these may result complications and a prolonged procedure time.
We herein report a case of acute myocarditis possibly related to the second dose an mRNA-coronavirus disease 2019 vaccine in 45-year-old woman with no remarkable medical history. She had fever for one week following mRNA-1273 severe respiratory syndrome coronavirus 2 vaccine. One later, she presented chest pain and electrocardiogram changes. Her serum troponin levels were elevated upon admission. Echocardiography showed segmental wall motion abnormalities apex, apical portion anterior...
Abstract In patients with multivessel disease (MVD), functional information on lesions improves the prognostic capability of SYNTAX score. Quantitative flow ratio (QFR®) is an angiography‐derived fractional reserve (FFR) that does not require a pressure wire or pharmacological hyperemia. We aimed to investigate feasibility QFR‐based patient in Heart Teams' discussions determine optimal revascularization strategy for MVD. hypothesized there acceptable agreement between treatment...
Background The fractional flow reserve (FFR) derived from coronary computed tomography (CT) angiography (FFRCT) is a variable tool for disease diagnosis that non-invasively provides the value of FFR. It can add physiological information to CT (CCTA) and reduce unnecessary invasive (CAG). However, it cannot be analyzed in some cases, which also called "non-measurability." While FFRCT has become globally widespread, current data on non-measurability are lacking. This study aimed determine rate...
Percutaneous left atrial appendage closure (LAAC) is an effective therapy to prevent thromboembolic events among patients with fibrillation (AF). However, since the (LAA) contributes volume and serves as a buffer for increasing pressure, this procedure may impair atrium (LA) compliance, enlarge LA, deteriorate diastolic function. In study, we sought investigate change in index (LAVI) following LAAC its effect on prognosis.
Abstract Background Percutaneous left atrium appendage closure (LAAC) is an effective therapy to prevent thromboembolic events among patients with atrial fibrillation (AF) (Ref 1). However, since the (LAA) potentially serves as a part of (LA) volume and buffer for increasing LA pressure, this procedure may impair compliance 2). Purpose In study, we sought investigate effect LAAC on function. Methods/Results The OCEAN-LAAC registry ongoing, multicentre Japanese including who underwent in...
Abstract Background Non-calcified aortic stenosis (AS) is rare and associated with a high risk of transcatheter valve embolization migration (TVEM) because complex calcification important for stable anchoring the prosthesis. Therefore, implantation (TAVI) non-calcified AS not preferred. However, universally accepted strategy TAVI in such patients yet established. Case summary A 69-year-old woman symptomatic severe surgical was admitted to our institution TAVI. Pre-procedural computed...
Abstract Purpose The fractional flow reserve derived from coronary computed tomography angiography (FFR CT ) cannot be analyzed in some cases (non-measurability). Current data on non-measurability is lacking. This study aimed to examine the rate and factors associated with daily clinical practice. Methods retrospective observational included consecutive patients who underwent FFR analysis at our hospital. primary outcome was (defined as an inability perform quantitative rate. Factors were...
Abstract Background Wire-based fractional flow reserve (FFR) is currently the golden standard in a physiological assessment for intermediate coronary artery stenosis (CAS). However, clinical advantage of FFR has been limited by its invasiveness. In previous study with small number participants (334 patients), three-dimensional quantitative angiography (3D-QCA)-based vessel (vFFR) shown non-inferiority to wire-based diagnostic accuracy. There no reports regarding relationship between vFFR and...
