ABSTRACT null null Background null Mitral regurgitation (MR) quantification by proximal isovelocity surface area (PISA) method remains challenging. Using computer models, this study aims to evaluate the accuracy of different PISA methods and quantify their errors. null null null Methods null Five functional MR (FMR) computer models of different geometric and tethering abnormalities were created, validated and treated as phantom models, from which the reference values were directly obtained. Virt...

Abstract null null Background null Sports training triggers exercise-induced cardiac remodeling (EICR). Sprint- and endurance-trained master athletes are exposed to different hemodynamic stimuli accompanied by aging. We aimed to compare EICR types in light of the Morganroth hypothesis, frequency of abnormalities, and relationships between cardiac traits and age. null null null Methods null In our observational cross-sectional study, we performed echocardiographic examinations in 142 sprint-train...

BACKGROUND The relationship between myocardial work assessment using pressure-strain loops by echocardiography before cardiac resynchronization therapy (CRT) and response to CRT has been recently revealed. Among myocardial work parameters, the impact of left ventricular myocardial global wasted work (GWW) on response to CRT and outcome following CRT has been seldom studied. Hence, the authors evaluated the relationship between preprocedural GWW and outcome in a large prospective cohort of patien...

Background null Tricuspid valve regurgitation (TR) is a risk factor for morbidity and mortality in children with hypoplastic left heart syndrome (HLHS). Surgical tricuspid valve (TV) repair is common, but durable repair remains challenging. The aim of this study was to examine mechanisms of TR requiring surgery, features associated with unsuccessful repair, and TV changes after surgical repair. null null null Methods null Thirty-six patients with HLHS requiring TV repair (TVR) and 36 matched con...

BACKGROUND Transthoracic echocardiography (TTE) is increasingly utilized for guiding transcatheter closure of patent ductus arteriosus (PDA) in extremely low birth weight (ELBW) infants. The objectives of this study were to compare PDA size measurements by TTE with angiographic measurements and to describe TTE techniques used in guiding transcatheter PDA closure (TCPC) in ELBW infants. METHODS 125 consecutive ELBW infants (gestational age < 27-weeks, birth weight < 1kg) who underwent TCPC before...

BACKGROUND: Intraplaque neovascularization (IPN) in advanced lesions of the carotid artery has been linked to plaque progression and risk of rupture. Quantitative measurement of IPN may provide a more powerful tool for the detection of such "vulnerable" plaque than the current visual scoring grading method. The aim of this study was to develop a phantom platform of a neovascularized atherosclerotic plaque within a carotid artery to assess new methods of quantifying IPN. METHODS: Ninety-two synth...

Introduction null Defect size is an essential determinant of shunt severity in children with ventricular septal defect (VSD). Three-dimensional echocardiography (3DE) can better estimate VSD dimensions than two-dimensional echocardiography (2DE). We hypothesize that VSD area obtained by 3DE could better predict shunt severity than VSD diameters obtained from both 2DE and 3DE in children with isolated VSD. null null null Method null Children with isolated VSD were prospectively included. Patients...
