A ventricular septal defect arises when the superior part of the interventricular septum, which separates the right and left ventricles of the heart, fails to fully develop. The right ventricle pumps blood to the lungs to get oxygen, while the left ventricle pumps blood to the rest of the body to provide oxygen to tissues.
Rupture of the interventricular septum will cause a ventricular septal defect. Rupture of a papillary muscle will cause acute mitral regurgitation. [citation needed] The rupture will most often occur near the edge of the necrotic myocardium where it abuts healthy (but hyperemic) myocardium where the inflammatory response is at its greatest.
Management is a mixture of medical (eg pain relief, respiratory support, chest drainage and antibiotics), non-medical (physiotherapy and rehabilitation) and surgical (fixation of rib fractures if appropriate and operative treatment of cardiac, lung, airway, diaphragm and oesophageal injuries).
A blunt cardiac injury is an injury to the heart as the result of blunt trauma, typically to the anterior chest wall.It can result in a variety of specific injuries to the heart, the most common of which is a myocardial contusion, which is a term for a bruise (contusion) to the heart after an injury.

Also called compression-rupture lacerations, type 1 are the most common type and usually occur in a central location of the lung. [1] They tend to be large, ranging in size from 2–8 cm. [ 19 ] The shearing stress in type 2 results when the lower chest is suddenly compressed and the lower lung is suddenly moved across the vertebral bodies.
Atrioventricular septal defect (AVSD) or atrioventricular canal defect (AVCD), also known as "common atrioventricular canal" or "endocardial cushion defect" (ECD), is characterized by a deficiency of the atrioventricular septum of the heart that creates connections between all four of its chambers. It is a very specific combination of 3 defects:
A pneumatocele is a cavity in the lung parenchyma filled with air that may result from pulmonary trauma during mechanical ventilation. [1] Gas-filled, or air-filled lesions in bone are known as pneumocysts. [2] When a pneumocyst is found in a bone it is called an intraosseous pneumocyst, or a vertebral pneumocyst when found in a vertebra. [3]
Diaphragmatic rupture (also called diaphragmatic injury or tear) is a tear of the diaphragm, the muscle across the bottom of the ribcage that plays a crucial role in breathing. Most commonly, acquired diaphragmatic tears result from physical trauma .
