An assessment of the quality of optical coherence tomography image acquisition
AbstractOptical coherence tomography (OCT) provides excellent image resolution, however OCT optimal acquisition is essential but could be challenging owing to several factors. We sought to assess the quality of OCT pullbacks and identify the causes of suboptimal image acquisition. We evaluated 784 (404 pre-PCI; 380 post-PCI) coronary pullbacks from an anonymized OCT database from our Cardiovascular Imaging Core Laboratory. Imaging of the region-of-interest (ROI —lesion or stented segment plus references) was incomplete in 16.1% pullbacks, caused by pullback starting too proximal (63.7%), inappropriate pullback length...

Comment on “The relationship between atherogenic index of plasma and no‑reflow in patients with acute ST‑segment elevation myocardial infarction who underwent primary percutaneous coronary intervention”
AbstractWe read with great pleasure the interesting study evaluating “The relationship between atherogenic index of plasma (AIP) and no-reflow in patients with acute ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention” by Süleymanoğlu M et al. The most important problem in the study was that they miscalculated the ir patients' AIP values. As a result of this miscalculation, all patients seemed to be at high cardiac risk. When calculating AIP, the unit of both triglyceride (TG) and high-density lipoprotein (HDL) levels should be taken in mmol. In calculating ...

Predictive value of electrocardiography-gated myocardial perfusion imaging to new-onset heart failure in patients with chronic kidney disease: findings from the J-ACCESS 3 study
AbstractThe incidence of heart failure (HF) increases in patients with chronic kidney disease (CKD). Factors that could predict patients with CKD who are at high risk for developing HF should be identified. We analysed clinical parameters and stress/rest myocardial perfusion imaging (MPI) findings derived from 499 patients with CKD by the Japanese Assessment of Cardiac Events and Survival Study by Quantitative Gated SPECT 3 (J-ACCESS 3) to clarify predictors of new-onset HF. Forty-one patients with congestive HF in the J-ACCESS 3 database were followed up for three years. Multivariable Cox hazards models selected haemoglob...

Septal flash is a prevalent and early dyssynchrony marker in transcatheter aortic valve replacement-induced left bundle branch block
This study aims to (1) assess echocardiographic dyssynchrony in acute TAVR-induced LBBB (TAVR-LBBB), and (2) compare dyssynchrony parameters among different patient groups with LBBB. The study enrolled all TAVR-LBBB patients at Ghent University Hospital between 2013 and 2019. First, acute TAVR-LBBB dyssynchrony was assessed by: (1) septal flash (SF); (2) interventricular mechanical delay (IVMD; cut-off  ≥ 40 ms) and (3) presence of ‘classical dyssynchronous strain pattern’ assessed with speckle tracking. Secondly, acute TAVR-LBBB patients with SF (LBBBTAVR+SF) were compared to randomly sel...

A multi-vendor, multi-center study on reproducibility and comparability of fast strain-encoded cardiovascular magnetic resonance imaging
AbstractMyocardial strain is a convenient parameter to quantify left  ventricular (LV) function. Fast strain-encoding (fSENC) enables the acquisition of cardiovascular magnetic resonance images for strain-measurement within a few heartbeats during free-breathing. It is necessary to analyze inter-vendor agreement of techniques to determine strain, such as fSENC, in order to compare existing studies and plan multi-center studies. Therefore, the aim of this study was to investigate inter-vendor agreement and test-retest reproducibility of fSENC for three major MRI-vendors. fSENC-images were acquired three times in t...

Appropriate selection of echocardiographic guidance for transcatheter atrial septal defect closure
AbstractTransesophageal echocardiography (TEE) under general anesthesia (GA) or intracardiac echocardiography (ICE) under sedation is usually used for echocardiographic guidance during transcatheter atrial septal defect (ASD) closure. However, appropriate selection of guidance has not been fully established. Our study aimed to evaluate whether selection of guidance depending on anatomic ASD features and TEE tolerability under sedation contributes to procedure success. On the basis of anatomic ASD characteristics and TEE tolerability under sedation during the pre-procedural TEE, we selected either TEE, ICE, or combined TEE ...

Coronary artery volume index: a novel CCTA-derived predictor for cardiovascular events
AbstractCoronary computed tomography angiography (CCTA) provides critical prognostic information on plaque burden and stenosis severity of coronary arteries. We aimed to investigate the long-term prognostic value of coronary artery volume per myocardial mass as a potential new imaging parameter. Consecutive patients with suspected coronary artery disease (CAD) were included. Coronary artery volume index (CAVi) was defined as volume over myocardial mass. Additionally, obstructive CAD ( ≥ 70% stenosis) and segment severity score (SSS: sum of all segments scored according to lesion severity with 0 = no...

The association between epicardial adipose tissue thickness around the right ventricular free wall evaluated by transthoracic echocardiography and left atrial appendage function
AbstractEpicardial adipose tissue (EAT) is associated with the development of atrial fibrillation (AF). EAT thickness identified on transthoracic echocardiography (TTE). The relationship between EAT volume and left atrial appendage (LAA) function is not well-known. We aimed to investigate the associations between EAT thickness and LAA emptying flow velocity and LAA orifice area. This single-center retrospective study enrolled 202 patients who underwent both TTE and transesophageal echocardiography (TEE). EAT thickness was measured on TTE in parasternal long-axis view. We measured LAA orifice areas in 41 patients with 3-dim...
