	~~'''~~Crista Supraventricularis~~'''~~		== Crista Supraventricularis ==

	The '''~~Crista Supraventricularis~~''' is a ~~prominent~~ muscular ridge in the right ~~atrium~~ of the heart~~, extending~~ from the ~~front of the~~ atrium ~~and along~~ the right ~~side of the [[Atrioventricular orifice\|atrioventricular orifice]]. It is a significant anatomical feature of~~ the ~~[[Cardiovascular system\|cardiovascular system]]~~.		The '''crista supraventricularis''' is an important anatomical structure within the heart. It is a muscular ridge located in the right ventricle, separating the inflow tract from the outflow tract. This structure plays a crucial role in the proper functioning of the heart by directing blood flow from the right atrium to the right ventricle and then into the pulmonary artery.

	==Anatomy==		== Anatomy ==

	The ~~Crista Supraventricularis~~ is ~~a part of~~ the [[~~Right atrium\|right atrium~~]] and ~~is located in~~ the [[~~Heart\|heart~~]]. It is ~~a muscular ridge that separates~~ the ~~[[Tricuspid valve\|tricuspid valve]] from~~ the ~~[[Sinus venarum\|sinus venarum]], which is~~ the ~~part~~ of the right ~~atrium~~ that ~~receives~~ blood from the ~~[[Superior vena cava\|superior vena cava]]~~ and [[~~Inferior vena cava\|inferior vena cava~~]].		The crista supraventricularis is situated above the [[tricuspid valve]] and extends towards the [[pulmonary valve]]. It is part of the right ventricular outflow tract (RVOT) and is essential in maintaining the separation between the inflow and outflow tracts of the right ventricle. This separation ensures that blood flows efficiently from the right atrium through the tricuspid valve into the right ventricle, and then from the right ventricle through the pulmonary valve into the [[pulmonary artery]].

	~~==Function==~~		The primary function of the crista supraventricularis is to support the structural integrity of the right ventricle and to facilitate the proper routing of blood. By maintaining the separation between the inflow and outflow tracts, it helps prevent the mixing of oxygen-poor blood returning from the body with the oxygen-rich blood being pumped to the lungs.

	The primary function of the Crista Supraventricularis is to direct the flow of blood in the right atrium. It guides the blood from the superior and inferior vena cava towards the tricuspid valve, which then leads to the [[Right ventricle\|right ventricle]].		== Clinical Significance ==

	~~==Clinical Significance==~~		Abnormalities or defects in the crista supraventricularis can lead to various [[congenital heart defects]] or [[cardiac conditions]]. For instance, a prominent crista supraventricularis may be associated with [[right ventricular outflow tract obstruction]] (RVOTO), which can impede blood flow from the right ventricle to the pulmonary artery. Such conditions may require medical intervention or surgical correction to restore normal cardiac function.

	The Crista Supraventricularis is an important landmark in cardiac surgery, particularly in procedures involving the tricuspid valve or the right atrium. Its location and structure can also be affected by certain heart conditions, such as [[Congenital heart disease\|congenital heart disease]] and [[Cardiomyopathy\|cardiomyopathy]].		== Related Structures ==

'''Crista Supraventricularis'''

The '''Crista Supraventricularis''' is a prominent muscular ridge in the right atrium of the heart, extending from the front of the atrium and along the right side of the [[Atrioventricular orifice|atrioventricular orifice]]. It is a significant anatomical feature of the [[Cardiovascular system|cardiovascular system]].

==Anatomy==

The Crista Supraventricularis is a part of the [[Right atrium|right atrium]] and is located in the [[Heart|heart]]. It is a muscular ridge that separates the [[Tricuspid valve|tricuspid valve]] from the [[Sinus venarum|sinus venarum]], which is the part of the right atrium that receives blood from the [[Superior vena cava|superior vena cava]] and [[Inferior vena cava|inferior vena cava]].

==Function==

The primary function of the Crista Supraventricularis is to direct the flow of blood in the right atrium. It guides the blood from the superior and inferior vena cava towards the tricuspid valve, which then leads to the [[Right ventricle|right ventricle]].

==Clinical Significance==

The Crista Supraventricularis is an important landmark in cardiac surgery, particularly in procedures involving the tricuspid valve or the right atrium. Its location and structure can also be affected by certain heart conditions, such as [[Congenital heart disease|congenital heart disease]] and [[Cardiomyopathy|cardiomyopathy]].
