The most common cause of myocardial rupture is a recent myocardial infarction, with the rupture typically occurring three to five days after infarction. [3] Other causes of rupture include cardiac trauma, endocarditis (infection of the heart), [4] [5] cardiac tumors, infiltrative diseases of the heart, [4] and aortic dissection. [citation needed]
In acute MR secondary to a mechanical defect in the heart (i.e., rupture of a papillary muscle or chordae tendineae), the treatment of choice is mitral valve surgery. If the patient is hypotensive prior to the surgical procedure, an intra-aortic balloon pump may be placed in order to improve perfusion of the organs and to decrease the degree of MR.
The role of these macrophages is the removal of necrotic myocytes. However, these cells are directly involved in the weakening of the tissue, leading to complications such as a ventricular free wall rupture, intraventricular septum rupture, or a papillary muscle rupture. At a gross anatomical level, this staged is marked by a yellow pallor.
Papillary muscle rupture can be caused by a myocardial infarction, and dysfunction can be caused by ischemia. Rarely, blunt chest trauma can be the cause of papillary muscle rupture, resulting from the sudden deceleration or compression of the heart. [4] Complications may lead to worsening of mitral regurgitation. [5]

A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops in one of the coronary arteries of the heart, causing infarction (tissue death) to the heart muscle. [1] The most common symptom is retrosternal chest pain or discomfort that classically radiates to the left shoulder, arm, or jaw. [1]
This is a shortened version of the thirteenth chapter of the ICD-9: Diseases of the Musculoskeletal System and Connective Tissue. It covers ICD codes 710 to 739 . The full chapter can be found on pages 395 to 415 of Volume 1, which contains all (sub)categories of the ICD-9.
