Traumatic Atrial Septal Defect with Tricuspid Regurgitation Following Blunt Chest Trauma Presenting as Hypoxemia: A Case Report.

Introduction: Although myocardial injury is common after blunt chest trauma, tricuspid valve injury associated with traumatic atrial septal defect resulting in acute hypoxia is an infrequent event. We report an unusual case of blunt chest trauma referred to us for unexplained hypoxemia, emphasizing the unusual nature of injury and the importance of comprehensive cardiac evaluation in such cases.

Case Report: A 35-year-old male presented to the emergency department after falling from a tree from an approximate height of 15 feet.

Left ventricular diastolic function and cardiotoxic chemotherapy.

Background: Left ventricular ejection fraction falls when the myocardium has already lost a significant portion of its functional capacity. There are conflicting data on whether diastolic dysfunction precedes systolic dysfunction after cardiotoxic chemotherapy. We aimed to study systolic and diastolic dysfunction after cardiotoxic chemotherapy and whether diastolic dysfunction can predict subsequent risk of systolic dysfunction.
