Two-dimensional speckle tracking imaging cardiac motion-based quantitative evaluation of global longitudinal strain among patients with coronary Heart Disease and functions of left ventricular ischemic myocardial segment
AbstractTo investigate two-dimensional speckle tracking imaging (2D-STI)-based quantitative evaluation of the influences of different levels of coronary artery stenosis on left ventricular functions and its clinical diagnostic values, 120 patients with coronary heart disease (CHD) were divided into control group (30 cases), mild stenosis group (30 cases), moderate stenosis group (30 cases), and severe stenosis group (30 cases) according to coronary angiography (CAG) results. They underwent routine ultrasound examination and 2D-STI examination. Receiver operating characteristic (ROC) curves were drawn to evaluate the sensit...

Assessment of left ventricular global longitudinal strain in patients with hypertrophic cardiomyopathy and coronary artery disease
AbstractImpaired left ventricular global longitudinal strain (GLS) and coronary artery disease (CAD) each confer adverse prognosis in hypertrophic cardiomyopathy (HCM). Despite their prevalence, data on GLS in co-existent HCM and CAD is lacking.  Ninety-six patients with HCM and CAD were retrospectively identified between 2005 and 2021, and analyzed using 2D speckle-tracking echocardiography. Obstructive and non-obstructive CAD patients were compared, multivariate linear regression tested associations between clinical and echocardiographic variables with GLS, and Receiver Operating Characteristic Curve assessed the utilit...

Aortic stenosis and right ventricular dysfunction
AbstractAt the present time, right ventricular function in patients with aortic stenosis is insufficiently taken into account in the decision-making process of aortic valve replacement. The aim of our study was to evaluate significance of right ventricular dysfunction in patients with severe aortic stenosis by modern 3D echocardiographic methods. This is prospective analysis of 68 patients with severe high and low-gradient aortic stenosis. We evaluated function of left and right ventricle on the basis of 3D reconstruction. Enddiastolic, endsystolic volumes, ejection fraction and stroke volumes of both chambers were assesse...

The current and future role of imaging of thoracic aortic disease: a North American society for cardiovascular imaging commentary on the 2022 AHA/ACC guidelines for the diagnosis and management of aortic disease
AbstractThe 2022 AHA/ACC Guidelines for the Diagnosis and Management of Aortic Disease introduced important updates for managing thoracic aorta aortic disease (TAD). In particular, the Guidelines underscore multimodality imaging's role in diagnosis, risk assessment, and monitoring of patients with TAD. This commentary aims to distill key imaging aspects from the Guidelines to provide a concise reference for the cardiovascular imaging community. Primary areas of focus include: (1) The importance of imagers in the multidisciplinary TAD care team, (2) Appropriate imaging techniques along with their strengths and weaknesses, (...

Cardiac scintigraphy and echocardiography assessment in the diagnosis of transthyretin cardiac amyloidosis
AbstractThe aim is to evaluate the diagnostic yield of echocardiography and [99mTc]Tc-DPD scintigraphy in the detection of amyloid cardiomyopathy (CM) and define potential prognostic echocardiographic parameters. 133 patients were retrospectively studied, from 2016 to 2021, with a mean age of 80.2  ± 7.5 years. The final diagnosis was established according to international consensus. Patients had a transthoracic echocardiogram (TTE) and [99mTc]Tc-DPD scintigraphy; RWT, E/e, LS, TAPSE, SAB, and IWT scores were calculated. All patients with ATTR-CM were classified into 3 prognostic stages and were compared with Perugin...

Development of artificial intelligence-based slow-motion echocardiography and clinical usefulness for evaluating regional wall motion abnormalities
In conclusion, we successfully developed slow-motion echocardiography using in-between echocardiographic image interpolation. Although the accuracy for detecting RWMAs did not show a significant improvement with this method, we observed enhanced image readability and interreader agreement. This AI-based approach holds promise in supporting physicians’ evaluations. (Source: The International Journal of Cardiovascular Imaging)

Renal and cardiovascular prognostic significance of echocardiographic early diastolic mitral annular velocity in IgA nephropathy
AbstractIn chronic kidney disease (CKD), as in IgA nephropathy (IgAN), cardiovascular (CV) mortality and morbidity are many times higher than in the general population, and diastolic dysfunction (LVDD) has prognostic significance as well. Tissue Doppler Echocardiography (TDI) is another method for measuring myocardial contractility and determining diastolic dysfunction. 79 IgAN patients (age 46  ± 11 years) with CKD stages 1–3 were investigated and followed for 70 ± 28.7 months. Doppler echocardiography was used to measure the E (early) and A (late) waves, as well as the E wave deceleration time (EDT) during ...

CCTA-based CABG SYNTAX Score: a tool to evaluate completeness of coronary segment revascularization after bypass surgery
AbstractTo describe the updated coronary computed tomographic angiography (CCTA)-based coronary artery bypass graft (CABG) anatomic SYNTAX Score (aSS) and assess its utility and reproducibility for assessing the completeness of revascularization after CABG.  The CCTA-CABG aSS is a visual assessment using CCTA post-CABG which quantifies the failure in effectively grafting stenotic coronary segments, and therefore assesses the completeness of surgical revascularization. It is calculated by subtracting the aSS of successfully anastomosed coronary segment s from the aSS of the native coronary tree. The inter-observer reproduc...

Significantly elevated hepatic extracellular volume in adult patients with a Fontan circulation and its correlation with impaired functional capacity
This study aimed to compare the liver ECV between Fontan patients and other congenital heart diseases with significant pulmonic regurgitation (PR) or tricuspid regurgitation (TR), and to evaluate the correlation between the liver ECV in adult Fontan patients and their functional capacity as well as clinical characteristics. Retrospective analysis of cardiovascular magnetic resonance imaging from patients with history of Fontan surgery between 2017 and 2021 were conducted. The clinical characteristics and liver ECV were evaluated and compared between patients and control group. Functional capacity was evaluated using a 6-mi...

Characterization of pulmonary arterial stiffness using cardiac MRI
AbstractPulmonary arterial stiffness (PAS) is a pathologic hallmark of all types of pulmonary hypertension (PH). Cardiac MRI (CMR), a gold-standard imaging modality for the evaluation of pulmonary flow, biventricular morphology and function has been historically reserved for the longitudinal clinical follow-up, PH phenotyping purposes, right ventricular evaluation, and research purposes. Over the last two decades, numerous indices combining invasive catheterization and non-invasive CMR have been utilized to phenotype the character and severity of PAS in different types of PH and to assess its clinically prognostic potentia...

Left ventricular fibrosis and CMR tissue characterization of papillary muscles in mitral valve prolapse patients
ConclusionsCMR imaging in MVP patients referred for surgery shows a dark-appearance of the PM with higher T1 and ECV values compared with healthy volunteers. The presence of a positive DB-LGE at the posteromedial PM by CMR may serve as a better predictor of biopsy-proven LV inferobasal fibrosis than conventional CMR techniques.

Cardiac MRI of characteristic motion findings in right bundle branch block
AbstractWhile there have been many descriptions of characteristic motion findings in left bundle branch block (LBBB), there are few published descriptions of such findings in right bundle branch block (RBBB).  The purpose of this study was to assess the frequency of particular regional motion findings in cardiac magnetic resonance imaging (CMR) studies of patients with RBBB, compared with normal subjects. We focused on three distinctive motion patterns that can be seen in RBBB during early systole: dela yed apex-ward motion of the RV base, “reverse septal flash”, and “basal bulge”. The presence and relative magnit...
