Agenesia de cava superior associada a bloqueio atrioventricular de 3º grau Agenesis of the right superior vena cava associated with total heart block

Brazilian Journal of Cardiovascular Surgery, 2008
A persistência de veia cava superior esquerda com ausência da veia cava superior é uma anomalia rara, principalmente quando associada a bloqueio atrioventricular de 3º grau.

Mitochondrial Ca2+ uniporter haploinsufficiency leads to sexually dimorphic redox imbalance and metabolic remodelling in the mouse brain

The Journal of Physiology, EarlyView.
Abstract figure legend The genetic inactivation of one Mcu allele leads to sex‐specific changes in neuronal function in adult mice, that is, the firing of action potentials and the relationship between cytosolic and mitochondrial Ca2+ levels. The ability to produce NAD(P)H by stimulated neural tissue is largely preserved in male mice but delayed in ...

Changes in the dimensions of the venae cavae

, 1959
In 11 dogs a variable resistance gauge, a bonded strain gauge, or mutual inductance coils were installed on the venae cavae under aseptic surgical conditions so that dimensional changes in unexposed veins could be measured directly.

The isolated working guinea pig heart: A functional and electrophysiological characterisation

Experimental Physiology, Volume 111, Issue 7, Page 3137-3151, 1 July 2026.
Abstract Small animal isolated perfused hearts have been used for over 150 years for the study of cardiac physiology and pharmacology. The guinea pig heart represents the smallest mammalian heart that replicates key features of the human heart – for example, with respect to cardiac action potential duration, ion channel expression, excitation ...

Circumference of the venae cavae in computer tomography in patients with and without tricupid regurgitation

, 2017
Die Trikuspidalklappeninsuffizienz (TI) hat eine zunehmende Prävalenz und kann mit einer erhöhten Mortalität einhergehen. Sie kann primär auftreten, ist aber überwiegend sekundäre Folge einer Erkrankung des linken Herzens.

Venae cavae flow pattern in cats: as studied with high-speed cinefluorographic technique

, 1960
Movements of Lipiodol droplets were studied in the venae cavae of cats by high-speed cinefluorography at 260 frames/sec. Oscilloscopic tracings of simultaneous cardiac events were recorded on the same movie film.
