Heart Failure in Humans Reduces Contractile Force in Myocardium from Both Ventricles [PDF]

open access: yes, 2020
This study measured how heart failure affects the contractile properties of the human myocardium from the left and right ventricles. The data showed that maximum force and maximum power were reduced by approximately 30% in multicellular preparations from

Twisted atrioventricular connections in double inlet right ventricle: evaluation by magnetic resonance imaging [PDF]

open access: yes, 2008
Twisted atrioventricular connections occur almost exclusively in the hearts with biventricular atrioventricular connections. Only one example of double inlet left ventricle has been illustrated in which the axes of the two atrioventricular valves crossed

Disorders of cardiac hemodynamic in attack period of bronchial asthma in children [PDF]

open access: yesMedičnì Perspektivi, 2016
By dopplerechocardiography method there was studied functional state of cardiac ventricles and character of hemodynamic disorders in 48 patients aged 5-17 years in attack period of moderately-severe and severe bronchial asthma.

Use of the Left Ventricular Internal Dimension at End-Diastole and the E-Point Septal Separation Ratio in the Prediction of the Left Ventricular Systolic Function in Patients with Midrange and Reduced Ejection Fractions: A Pilot Study

open access: yesJournal of Tehran University Heart Center, 2019
Background: The aim of this study was to investigate the ability of a new index, namely the left ventricular internal dimension at end-diastole/mitral valve E-point septal separation (LVIDd/EPSS), to predict the left ventricular (LV) systolic function ...

Kcne4 deletion sex- and age-specifically impairs cardiac repolarization in mice. [PDF]

open access: yes, 2015
Myocardial repolarization capacity varies with sex, age, and pathology; the molecular basis for this variation is incompletely understood. Here, we show that the transcript for KCNE4, a voltage-gated potassium (Kv) channel β subunit associated with human

The effects of repetitive electric cardiac stimulation in dogs with normal hearts, complete heart block and experimental cardiac arrest [PDF]

open access: yes, 1955
Direct cardiac stimulation was conducted in the open chest. In normal animals, auricular stimulation at frequencies faster than the spontaneous rate caused little change in vascular pressures or cardiac output.

A heart within the heart: double-chambered left ventricle [PDF]

open access: yesEuropean Heart Journal - Cardiovascular Imaging, 2008
We describe a rare congenital anomaly in a 49-year-old woman who presented with palpitations and slightly reduced exercise capacity. A double-chambered left ventricle was suspected on echocardiography and confirmed by cardiac computed tomography scanning, cardiac magnet resonance imaging, and invasive angiography.

CRISS - CROSS HEART (Report of four cases)

open access: yesMajalah Kardiologi Indonesia, 2013
Criss-cross heart is a rare congenital cardiac anomaly characterized by crossing of the inflow streams of the two ventricles. The anomaly seems to be due to abnormal twisting of the heart about its long axis and when the axis of the openings of the ...

Blood Flow Disturbance and Morphological Alterations Following the Right Atrial Ligation in the Chick Embryo

open access: yesFrontiers in Physiology, 2022
Collectively known as congenital heart defects (CHDs), cardiac abnormalities at birth are the most common forms of neonatal defects. Being principally responsible for the heart‘s pumping power, ventricles are particularly affected by developmental ...

Parasympathetic and sympathetic axons are bundled in the cardiac ventricles and undergo physiological reinnervation during heart regeneration

open access: yesiScience, 2023
Summary: Sympathetic innervation influences homeostasis, repair, and pathology in the cardiac ventricles; in contrast, parasympathetic innervation is considered to have minimal contribution and influence in the ventricles.
