Heritable thoracic aortic disease is caused by dominantly inherited mutations in more than a dozen genes, including mutations that cause Loeys-Dietz syndrome. McGovern Medical School at UTHealth Houston convenes a regular conference that includes cardiothoracic and vascular surgeons, cardiologists, geneticists, radiologists, and pathologists to formulate multidisciplinary approaches for the management of complex heritable thoracic aortic disease cases. In this report, we highlight the unique management of individuals with distinct presentations of Loeys-Dietz syndrome owing to mutations.

Article Synopsis
  • The review discusses the pathobiology of acute myocardial infarction, highlighting the mechanisms behind ischemic and toxic injury in heart cells, with insights gained over the past seventy years from the author's extensive research experience.
  • It emphasizes the role of increased intracellular calcium and ATP depletion in the progression of cardiomyocyte injury, identifying oncosis as a key early stage of injury that can lead to irreversible cell damage.
  • The study also explores how different energy impairment levels in cardiomyocytes can result in varying types of cell death, including apoptosis and autophagy, and discusses ongoing efforts to translate these findings into treatments for heart conditions.

Fabry's disease, also known as Anderson-Fabry Disease (AFD), is caused by mutations in the α galactosidase A (α GalA) gene found on the X chromosome. This condition results in an accumulation of sphingolipids, including globotriaosylceramide (Gb3), in cells throughout the body. The main effects of Fabry disease typically involve heart, kidney, and nervous system complications.

Primary cardiac angiosarcoma is a rare, aggressive malignancy that commonly metastasizes to various organs. The presenting symptoms are typically nonspecific, so a comprehensive examination is required to confirm the diagnosis promptly. This case report describes the presentation of an older patient with a history of neoplasms.

The large spectrum of etiologies, severities, and histologic appearances of eosinophilic myocarditis (EoM) poses challenges to its diagnosis and management. Endomyocardial biopsy is the current gold standard for diagnosis. However, cardiovascular magnetic resonance imaging is becoming more frequently used to diagnose acute myocarditis because of enhanced sensitivity when compared to histopathologic examination, and its less invasive nature.
