Axillary Artery Pseudoaneurysm Following Percutaneous Transaxillary Access For Impella Device Placement During Percutaneous Coronary Intervention, Anas A. Alharbi, Fahad S. Alqahtani, Peter Farjo, Jason A. Moreland

Internal Medicine Faculty Publications

Percutaneous transaxillary access is currently considered an acceptable alternative to transfemoral approach for large-bore access, especially in the setting of hostile iliofemoral arteries. Few published reports exist concerning complications of upper extremity access. We describe development of an axillary artery pseudoaneurysm and its management following transaxillary access. (Level of Difficulty: Advanced.)

Regulation Of Myofilament Contractile Function In Human Donor And Failing Hearts, Kerry S. Mcdonald, Laurin M. Hanft, Joel C. Robinett, Maya Guglin, Kenneth S. Campbell

Internal Medicine Faculty Publications

Heart failure (HF) often includes changes in myocardial contractile function. This study addressed the myofibrillar basis for contractile dysfunction in failing human myocardium. Regulation of contractile properties was measured in cardiac myocyte preparations isolated from frozen, left ventricular mid-wall biopsies of donor (n = 7) and failing human hearts (n = 8). Permeabilized cardiac myocyte preparations were attached between a force transducer and a position motor, and both the Ca²⁺ dependence and sarcomere length (SL) dependence of force, rate of force, loaded shortening, and power output were measured at 15 ± 1°C. The myocyte preparation size was …

Background

Chagas disease, caused by the parasite Trypanosoma cruzi, once considered a disease confined to Mexico, Central America, and South America, is now an emerging global public health problem. An estimated 300 000 immigrants in the United States are chronically infected with T. cruzi. However, awareness of Chagas disease among the medical community in the United States is poor.

Methods

We review our experience managing 60 patients with Chagas disease in hospitals throughout the New York City metropolitan area and describe screening, clinical manifestations, EKG findings, imaging, and treatment.

Results

The most common country of origin of our patients …
