Master of the Masquerade: An Atypical Presentation of Acute Aortic Dissection.

Acute aortic dissection (AAD) is associated with unacceptably high mortality rate. As such, early diagnosis and aggressive management are essential in order to avoid life-threatening complications. Herein, we report an atypical presentation of AAD and clinical sequelae.

Toward Resiliency in the Joint Blood Supply Chain.

The Joint military community provides a wide array of medical support services to its personnel, including the transfusion of blood and blood products. Ensuring that blood remains available and safe for transfusion requires sophisticated logistical support, especially for the military community's provision of blood to medical operations around the globe. However, that supply chain may become brittle in future potential operating environments, such as large-scale combat operations where adversaries may contest the U.

Rapid Desensitization to Overcome Contrast Allergy Prior to Urgent Coronary Angiography.

Allergic reactions to contrast media are a frequently reported complication of coronary angiography. The majority of patients experience mild, self-limited episodes, but in rare cases patients may experience severe, persistent symptoms. A strategy of premedication with corticosteroids and anti-histamines and an optimal selection of contrast agent is almost always successful in averting contrast reactions, yet a select few patients will continue to have breakthrough events.

Improvements in Left Ventricular Diastolic Mechanics After Parachute Device Implantation in Patients With Ischemia Heart Failure: A Cardiac Computerized Tomographic Study.

Background: Percutaneous ventricular restoration therapy with the use of a left ventricle (LV)-partitioning Parachute device has emerged as a clinical treatment option for LV apical aneurysm after extensive anterior myocardial infarction (AMI). We assessed changes of diastolic mechanics and functional improvements following LV Parachute device implantation by means of cardiac computerized tomography (CCT).

Methods And Results: CCT data were obtained from 28 patients before and after LV Parachute device implantation.
