Proteasome inhibitors such as bortezomib and carfilzomib have been used effectively to treat patients who have certain hematologic malignancies. Proteasome activity is elevated in the heart, and potent inhibition results in accumulation of misfolded intracellular protein aggregates and apoptosis. Heart failure, conduction disturbances, and premature atherosclerosis have been associated with bortezomib therapy.

Among the rare extrapulmonary manifestations, cardiac involvement is most prevalent, in the forms of myocarditis, pericarditis, postcardiotomy syndrome, and prosthetic valve endocarditis. Mechanical circulatory support has proved to be a safe and effective bridge to myocardial recovery in patients with acute fulminant myocarditis; however, to our knowledge, this support has not been used in infectious myocarditis specifically related to Legionellosis.

Even though many clinicians consider them to be part of the normal aging process, evidence suggests an association between Lambl's excrescences and ischemic stroke, migrainous headaches, and acute coronary syndromes. As a thin filamentous structure, a Lambl's excrescence is better detected and characterized with transesophageal than with transthoracic echocardiography.

A 74-year-old woman with paroxysmal atrial fibrillation underwent left atrial appendage (LAA) exclusion with a LARIAT snare device. Transesophageal echocardiogram one month later demonstrated a left atrial thrombus at orifice of the completely occluded LAA that subsequently resolved with two months of anticoagulation. This case highlights that LAA ligation with LARIAT device continues to pose a risk for left atrial thrombosis in the immediate post-operative period.

The resultant endothelial damage and intraluminal spur formation can lead to iliac deep vein thrombosis and sudden-onset left-lower-extremity edema and pain. Patients typically present with May-Thurner syndrome in their 2nd to 4th decades of life.

The transseptal passage of emboli from the right to the left cardiac chambers appears to play an important role. The therapeutic options are medical therapy (anti-aggregation or anticoagulation), surgical closure, or transcatheter closure.

In contrast, Vibrio vulnificus is a well-known cause of septicaemia, especially in patients with cirrhosis. We present a patient with V.

Withdrawal of ciprofloxacin in our patient resulted in complete resolution of ciprofloxacin-associated pseudotumor, as evidenced by a normal neuro-ophthalmic examination and a cerebrospinal fluid opening pressure of 140 mmH20.
Case Presentation: A 22-year-old African American woman presented with a headache of two weeks duration, visual blurring and horizontal diplopia after starting ciprofloxacin for pyelonephritis.
