In Vivo Dynamic Coronary Arteries Blood Flow Imaging Based on Multi‐Cycle Phase Clustering Ultrafast Ultrasound

open access: yesAdvanced Science
Echocardiography is the most primary clinical modality for dynamic cardiac imaging. However, the vigorous motion of myocardial tissue inherently causes inevitable signal aliasing between blood flow and myocardial tissue in traditional Doppler ultrasound ...

Physiological and clinical consequences of relief of right ventricular outflow tract obstruction late after repair of congenital heart defects. [PDF]

open access: yes, 2006
BACKGROUND: Right ventricular outflow tract obstruction (RVOTO) is a common problem after repair of congenital heart disease. Percutaneous pulmonary valve implantation (PPVI) can treat this condition without consequent pulmonary regurgitation or ...

Prevalence of transthyretin cardiac amyloidosis in undifferentiated heart failure with preserved ejection fraction

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1176-1182, April 2025.
Abstract Aims Transthyretin amyloid cardiomyopathy (ATTR‐CM) is an increasinglyrecognized cause of heart failure with preserved ejection fraction (HFpEF), which may be diagnosed non‐invasively using 99mTc 3,3‐diphosphono‐1,2‐propanodicarboxylic acid (DPD) scintigraphy‐based diagnostic criteria.

RELIABILITY OF DOPPLER ECHOCARDIOGRAPHIC STROKE VOLUME MEASUREMENT [PDF]

open access: yes, 1992
To evaluate the accuracy and utility of the echocardiographic Doppler method of determining the stroke volume, the stroke volume was measured in 64 instances in 15 patients and compared to the simultaneous thermodilution stroke volume determinations ...

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Considerations for drug trials in hypertrophic cardiomyopathy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1095-1112, April 2025.
Abstract Hypertrophic cardiomyopathy (HCM) is a heterogeneous condition with potentially serious manifestations. Management has traditionally comprised therapies to palliate symptoms and implantable cardioverter‐defibrillators to prevent sudden cardiac death. The need for disease‐modifying therapies has been recognized for decades.

Tissue Doppler study in the diagnosis of functional disorders of the myocardium in patients with chronic heart failure

open access: yesRUDN Journal of Medicine, 2010
The article presents a comparative analysis of standard echocardiography and tissue Doppler method Rings atrioventricular valves in patients with chronic heart failure with a view to early diagnosis of functional disorders of the myocardium.

Assessment of left ventricular functions in patients with Sjogren's syndrome using tissue doppler echocardiography

open access: yes, 2013
Aim: In our study, we aimed to evaluate left ventricular function in patients with Sjogren syndrome (SS) using tissue Doppler echocardiography (TDE) and myocardial performance index (MPI) in addition to conventional echocardiographic ...

A phenomap of TTR amyloidosis to aid diagnostic screening

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1113-1118, April 2025.
Abstract Cardiac amyloidosis due to transthyretin (ATTR) remains an underdiagnosed cause of cardiomyopathy. As awareness of the disease grows and referrals for ATTR increase, clinicians are likely to encounter more atypical forms of the condition in clinical practice.
