Histologic Examination of the Heart in the Forensic Autopsy.

Histologic examination of the myocardium, valves, and cardiac blood vessels is often as important as the gross examination. The diagnostic features and categories of heart disease are many and varied, possibly more than any other organ. We present a review of the histologic features of forensically important heart disease.

Clinical and pathologic findings of aortic dissection at autopsy: Review of 336 cases over nearly 6 decades.

Background: We aimed to characterize the clinical and pathologic findings of aortic dissection (AD) over a nearly 60-year period.

Methods: The Jesse E. Edwards Registry of Cardiovascular Disease database was queried for cardiac specimens from autopsies with AD as a diagnosis and compared 2 cohorts: early (1956-1992) and current (1993-2015).

Uhl's anomaly: perspective of fetal echocardiography and histopathological correlation.

We report a case of Uhl's anomaly imaged at 19 weeks of gestation by fetal echocardiography with pathological confirmation by anatomical gross heart specimen and tissue histology. Uhl's anomaly of the right ventricle is a rare cardiac disorder with isolated right ventricular enlargement with almost complete absence of the right ventricular myocardium.

Patho-Histological Findings of Annular Rupture Related to Left Ventricular Outflow Tract (LVOT) Calcification Following Transcatheter Aortic Valve Replacement (TAVR).

Peri-aortic hematoma has been recently described as a potentially life-threatening complication following transcatheter aortic valve replacement (TAVR). Patient- and procedure-related factors exist that predispose to peri-aortic hematoma formation, which can progress to myocardial rupture at the aortic root-myocardial junction. While conservative therapy with blood pressure control is the expectant management following peri-aortic hematoma formation, myocardial rupture can occur at the site of the aortic annulus.

Expression of cathepsin K and tartrate-resistant acid phosphatase is not confined to osteoclasts but is a general feature of multinucleated giant cells: systematic analysis.

Objective: Cathepsin K and tartrate-resistant acid phosphatase (TRAP) are two proteins expressed in osteoclastic giant cells. Recently we showed that lesional multinucleated giant cells (MNGs) in pulmonary granulomatosis with polyangiitis expressed these proteins. We aimed to clarify whether the expression of these two proteins has any specificity or is a general feature of MNGs associated with multiple types of granulomatous inflammation.

Sudden death due to spontaneous acute dissection of the left subclavian artery with rupture during postpartum period: a case report.

Subclavian artery dissection is usually associated with coexisting aortic disease. Isolated and spontaneous acute subclavian artery dissection is uncommon and rarely reported. In addition, no case of left subclavian artery dissection during pregnancy and early puerperium has been described.

Pathology of the aortic arch in hypoplastic left heart syndrome: surgical implications.

Aortic arch reconstruction plays an important role in the success of the Norwood procedure (NP) for hypoplastic left heart syndrome (HLHS). This study investigated the cardiac specimens to determine the etiology of distal aortic arch obstruction after the NP for HLHS and to locate coarctation of the aorta in HLHS untreated by surgery. This study examined 17 cardiac specimens: 9 that had NP and 8 not treated by surgery.

Sudden death with circumferential subepicardial fibrofatty replacement: left-sided arrhythmogenic ventricular cardiomyopathy.

We report 5 cases of sudden cardiac death, with similar cardiac findings. All 5 cases had circumferential left ventricular subepicardial fibrofatty replacement of the myocardium, similar to the histologic features of arrhythmogenic right ventricular cardiomyopathy (ARVC). In these cases, the findings were predominantly in the left ventricle with minimal or no involvement of the right ventricle.
