Autopsy | Johns Hopkins Medicine Ventricular fibrillation may present in the following ways and cause instantaneous/sudden death: Coronary arteries: Occlusion (atherosclerosis, thrombosis, embolus), structural abnormalities of the epicardial arteries, coronary artery dissection or aneurysm, Cardiomyopathies: Hypertrophic cardiomyopathy, dilated cardiomyopathy (genetic, myocarditis, toxic, peripartum, idiopathic), restrictive cardiomyopathy (idiopathic, amyloidosis, sarcoidosis, radiation fibrosis, metastasis, deposition disease/inborn errors of metabolism), Other cardiomyopathies: Arrhythmogenic right ventricular dysplasia, arrhythmogenic left ventricular dysplasia, left ventricular non-compaction, restrictive conditions (endomyocardial fibrosis, Loeffler endomyocarditis, endocardial fibroelastosis), Inflammatory: Myocarditis, pericarditis (bacterial, viral, Dressler syndrome), Valvular: Congenital abnormalities (bicuspid valve), rheumatic heart disease, Functional abnormalities: Long QT syndrome (LQTS), short QT syndrome (SQTS), catecholaminergic polymorphic ventricular tachycardia (CPVT), Brugada syndrome, Asian sudden unexplained nocturnal death syndrome (SUNDS). Pathology of Sudden Natural Death. An enlarged, globoid or flabby heart may indicate structural abnormalities such as hypertrophic or dilated cardiomyopathy, whereas a normally-sized but overly stiff heart is seen in restrictive cardiomyopathies. We avoid using tertiary references. HF0, or Hacker Fellowship Zero, is a start-up accelerator that provides 12-week residencies for batches of fellows from 10 different start-ups. The decedents past medical history and symptomatology before death may prove invaluable in interpreting the autopsy findings and in identifying a cause of death. Although many different types of hereditary and acquired diseases cause deaths in adults, natural deaths in children and young adults are more likely to be the result of congenital disorders, infections or malignancies. 2013 Aug. 108(8):1411-7. Natural death in the forensic setting: a study and approach to the autopsy. This photograph illustrates a type A aortic dissection with concomitant dissection of the pulmonary artery. Autopsy is a source of discovery that informs the way we think about disease systemically, says special issue co-editor Dr. Jeffrey E. Saffitz, the chair of the Another type of autopsy called a clinical or hospital autopsy, happens in a hospital setting with a pathologist and is requested by the family of the deceased to ascertain why their loved one may have passed away. Findings such as fingernail clubbing and splinter hemorrhages may be seen in chronic heart disease and bacterial endocarditis, respectively. Kotabagi RB, et al. (This may require interviewing emergency medical personnel or other first responders.). Firm, clotted material protruding out above the cut surface of the small- to medium-sized vessels can be seen with small pulmonary emboli; however, histologic conformation is required. The utility of postmortem microbiology has been debated, due to frequent contamination of postmortem cultures, use of antibiotics, and lack of agreement between antemortem and postmortem cultures. After the loss of blood pressure, the vessels tend to collapse and become difficult to see, even on cross-sectioning. [QxMD MEDLINE Link]. [14].

Before performing the autopsy, all attempts should be made to obtain and review a decedents past medical history in addition to any findings/information gathered by the death investigation team. Lymphohistiocytic myocarditis, trichrome stain. The square of tissue containing the SA node can be serially sectioned perpendicular terminal crest for embedding. [14], Special handling requirements for bodies and specimens from natural deaths are typically related to decreasing the transmission of infectious diseases. Philadelphia, Pa: Saunders/Elsevier; 2010. Other autopsy findings included pulmonary edema and ascites, as well as hypertensive changes in the lungs and early cardiac cirrhosis. In this section, evisceration techniques, dissection of the cardiac conduction system, and dissection in cases of suspected pulmonary embolism (PE) and deep vein thrombosis (DVT), pneumothorax, and gastroesophageal varices are briefly reviewed. The scapular soft tissue and galea should be examined for hemorrhages and contusions. [3, 15]. Is intestinal volvulus or herniation present? [QxMD MEDLINE Link].

Coronary artery dissection seen in a case of sudden death in a young woman. Pathology of Sudden Natural Death. Unexpected deaths may occur in previously healthy individuals and in those with known natural disease when the severity of the persons condition does not explain death. Other helpful information includes the following: Nodal vascular supply: Regarding the atrioventricular (AV) nodal artery, the right coronary artery (RCA) supply is greater than that of the left circumflex artery (LCx); the SA nodal artery is supplied by the RCA, Helpful stains: Masson trichrome, Movat pentachrome, Verhoeff-van Gieson. In cases that appear legitimately nonsuspicious and natural in nature, the indications can be thought of in two respects, as follows: Indications to perform a medicolegal death investigation and, Indications to perform an autopsy in an apparent natural death, The exact determinants in either situation may be somewhat dependent on the jurisdiction and/or medical examiner; however certain standards have been set.

Sudden death with circumferential subepicardial fibrofatty replacement: left-sided arrhythmogenic ventricular cardiomyopathy. Burton JL. The lung can be sectioned in coronal plane or serially sectioned in the horizontal plane. Are all organs present in normal anatomic position? This can happen during the course of a criminal investigation. After their removal, the lungs should be weighed individually. Pulmonary infarcts, usually due to systemic emboli, are more commonly seen in the lower lobes and in older individuals (who have a greater incidence of heart and lung disease, which decreases their ability to compensate for the hypoperfusion); the infarcts are raised, hyperemic, wedge-shaped areas arising at the periphery of the lung. Adolescents and young adults dying suddenly and unexpectedly from natural processes typically have some form of heart disease, of which hypertrophic cardiomyopathy is the most common. [5].

The first dissection in the abdomen is usually freeing up the large intestine. [8], Across all age groups, cardiac-related diseases play a significant role in both sudden and unexpected death. an estimate of when the death occurred, which becomes less accurate as time passes, body weight and other physical measurements, photographs to document bruises and other injuries. Determination of cause of death in natural deaths, particularly when the death occurred suddenly, unexpectedly, or in the young, is an important part of forensic autopsy A more specific alternate chemical method such as liquid chromatography-tandem mass spectrometry (LC-MS/MS) or gas chromatography-mass spectrometry (GC-MS) must be However, you can watch NBC's Hospitals can request autopsies when an individual dies under their care.

[15], Restrictive cardiomyopathy results from decreased myocardial compliance, typically secondary to fibrosis, but it can also be due to infiltrative processes such as amyloidosis or sarcoidosis, in addition to various deposition diseases; most causes of restrictive cardiomyopathy are secondaryhowever, rare cases of both familial and sporadic primary restrictive cardiomyopathy do occur; although the ventricular volume and ventricular wall thickness in restrictive cardiomyopathy is typically preserved or only slightly abnormal, the atria are frequently dilated; the diagnosis of a specific etiology is made by microscopic examination It can diagnose various health. Pathology of Sudden Natural Death. Myocardial hypertrophy can arise from a number of causes, both congenital and acquired; the weight of the heart is a better predictor of hypertrophy than is ventricular thickness. However, not all autopsies yield clear findings. The presence or absence of a note is not a substitute for a thorough investigation and autopsy; the note may have been removed from the scene before the arrival of investigators or, less commonly, the individual may die of a natural disease before carrying out their suicidal intentions, Review witness and family statements; it may be useful to speak with family members and witnesses yourself in order to better elicit a history of certain symptoms (eg, chest and arm pain) before death; a detailed medical history, however, is best obtained from the decedents physician rather than friends or relatives. 2010 May 10. [3, 6] Ancillary tests for microbiology and toxicology can be collected and sent immediately or stored for future use.
