Papillary muscle - Wikipedia
The papillary muscles are muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves (also known as the mitral and tricuspid valves) via the chordae tendineae and contract to prevent inversion or prolapse of these valves on …

2023年7月24日 · The papillary muscles of the heart are pillar-like muscles seen within the cavity of the ventricles, attached to their walls. They have an integral role in proper cardiac valvular function. They arise from the inner walls of the left and right ventricle and attach to mitral and tricuspid valve leaflets respectively via chordae tendinae.
Papillary Muscle Rupture - StatPearls - NCBI Bookshelf
2023年5月22日 · Papillary muscle rupture is a rare and potentially fatal complication that typically follows a myocardial infarction or occurs secondary to infective endocarditis. Acute rupture frequently results in severe mitral valve regurgitation, acute life-threatening cardiogenic shock, and pulmonary edema.
Papillary muscle - Function, Rupture and Pictures
2012年6月19日 · The Papillary muscles located in the left and right ventricles start contracting shortly prior to the ventricular systole. The contraction is maintained all through, which prevents backflow (regurgitation) of the blood of the ventricles into the atrial cavities.
Papillary muscles | Radiology Reference Article - Radiopaedia.org
2021年8月2日 · The papillary muscles are thick bands and ridges of endocardial-lined myocardium that project into the lumen of the cardiac ventricles. They essentially represent dominant ventricular trabeculae which attach to the cusps of the atrioventricular valves via the chordae tendineae.
Heart ventricles: Anatomy, function and clinical aspects - Kenhub
2023年8月3日 · Contraction of the papillary muscles precedes ventricular contraction. It results in the apposition of the tricuspid leaflets, thus occluding the valve orifice and preventing backflow of blood during ventricular contraction.
Papillary Muscles | Atlas of Human Cardiac Anatomy
The three papillary muscles of the right ventricle have highly variable anatomy with the anterior papillary muscle usually being the most prominent. The anterior and septal papillary muscles are connected by the moderator band.
