A Wireless, Wearable Carotid Doppler Ultrasound Aids Diagnosis and Monitoring of Pericardial Tamponade: A Case Report

open access: yesCritical Care Explorations, 2023
BACKGROUND:. Pericardial tamponade can often be diagnosed through clinical findings and echocardiography; however, the diagnosis can be aided by demonstrating the hemodynamic consequences of the effusion. We describe the use of a wearable carotid Doppler

Changes in left atrial deformation in hypertrophic cardiomyopathy: Evaluation by vector velocity imaging. [PDF]

open access: yes, 2012
OBJECTIVES: Hypertrophic cardiomyopathy (HCM) represents a generalized myopathic process affecting both ventricular and atrial myocardium. We assessed the global and regional left atrial (LA) function and its relation to left ventricular (LV) mechanics ...

Isovolumic relaxation strain imaging is an accurate and sensitive approach for detection of active diastolic dysfunction: A preclinical study

open access: yesAnimal Models and Experimental Medicine, EarlyView.
A modified approach was developed to accurately identify the isovolumetric relaxation time (IVRT) using an apical three‐chamber view. Compared with conventional echocardiography, isovolumic relaxation strain imaging (IVSI) helps to detect the earlier alternations of diastolic function in transverse aortic constriction (TAC) mice.

A case of hypertrophic cardiomyopathy combined with muscular ventricular septal defect and abnormal origin of right coronary artery

open access: yesBMC Cardiovascular Disorders, 2019
Background Hypertrophic cardiomyopathy (HCM) is a myocardial disease. However, the coexistence of HCM with muscular ventricular septal defect (VSD), especially those with both incomplete spontaneous closure and coronary abnormal origin, is relatively ...

Cardiac imaging in athlete’s heart: current status and future prospects

open access: yesCardiovascular Ultrasound, 2023
Background Physical activity contributes to changes in cardiac morphology, which are known as “athlete’s heart”. Therefore, these modifications can be characterized using different imaging modalities such as echocardiography, including Doppler (flow ...

Techniques for Identification of Left Ventricular Asynchrony for Cardiac Resynchronization Therapy in Heart Failure [PDF]

open access: yes, 2005
The most recent treatment option of medically refractory heart failure includes cardiac resynchronization therapy (CRT) by biventricular pacing in selected patients in NYHA functional class III or IV heart failure. The widely used marker to indicate left

Doppler Echocardiography [PDF]

open access: yesCirculation, 1973
A range-gated pulsed Doppler flowmeter has recently been developed that measures the average velocity of blood flow within a small tear-drop shaped (4 mm by 2 mm) sample volume. Unlike the continuous wave Doppler, the distance from the transducer face to the sampling site can be continuously varied by a range adjustment knob.

Age and gender effects on echocardiographic and histopathological cardiac phenotypes in healthy adult mice

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This study investigated the impact of age and sex on cardiac phenotypes in healthy adult C57BL/6J mice using echocardiography and histopathological analyses. Findings revealed that female mice demonstrated more pronounced global cardiac chamber dilation during aging.

Two-dimensional and Doppler echocardiographic findings of congenital coronary artery fistula

open access: yesThe Turkish Journal of Pediatrics, 1992
Three patients with coronary artery fistula confirmed by coronary angiography and surgery were studied using two-dimensional and Doppler echocardiography. Two of these patients had left coronary artery-right ventricle fistula.
