The Impella mechanical circulatory support (MCS) system is a catheter-based continuous flow cardiac assist device that is widely used in the treatment of cardiogenic shock in medical and surgical cardiac intensive care units. As with all forms of MCS, device-related complications remain a major concern, the incidence of which can be mitigated by adhering to a few fundamental concepts in device management. The purpose of this review is to comprehensively describe our strategy for managing, repositioning, and weaning the Impella catheter.

Left atrial fibrous band is a rare clinical and echocardiographic finding characterized by the presence of a fibrous band attached to the mitral valve. Diagnosis is accomplished with transesophageal echocardiography (TEE), live 3D imaging, or cardiac MRI. Most patients are asymptomatic and incidental findings. However, in rare cases, an atrial fibrous band can produce symptoms such as dyspnea on exertion, fatigue, and lightheadedness secondary to mitral regurgitation (MR) which can lead to heart failure if unattended to. More serious complications such as cardioembolic phenomenon can occur. We herein report a case of a 55-year-old male with hypertension who presented with dyspnea on exertion and chest pain. Transthoracic echocardiography (TTE) showed mitral valve prolapse with moderate to severe mitral regurgitation. TEE showed an atrial fibrous band. Given the patient’s poor exercise tolerance, he was taken to surgery for a mitral annuloplasty.

Biologic therapy has revolutionized the management of chronic inflammatory diseases, including inflammatory bowel disease (IBD). Before the initiation of therapy, it is critical to rule out prior infection of chronic hepatitis B virus (HBV) and tuberculosis (TB). However, screening for human immunodeficiency virus (HIV) is not as routinely completed. We present a case of a 56-year-old male on ustekinumab for the management of Crohn's disease, found to have undiagnosed human immunodeficiency virus (HIV) with progression to acquired immunodeficiency syndrome (AIDS).
