Anatomic variations of the cardiac valves and papillary muscles of the right heart.

摘要: This article reviews the right atrioventricular and pulmonary valves, along with their anatomic variations as well papillary muscles chordae tendineae of ventricle human heart. A brief anatomical background is given for every structure, a gross review embryological basis. Although normal morphology valve tricuspid, this not always case; its involve, firstly, number cusps accessory leaflets. Anatomic may occur in association other congenital anomalies syndromes. Also number, length shape are variable. can be clinical significance since play an important role contraction closure tricuspid so to prevent ventricular blood from passing back into atrium. The present cusps, stenosis or atresia, either isolated findings
