ABSTRACT
Aspergillus endocarditis is a fatal source of valvular infection with a near 100 % mortality rate if pharmacotherapy and valve-replacement surgery are not initiated swiftly after diagnosis. Complicating its diagnosis is the low yield for growth on standard blood culture and time requirements for molecular diagnostic tools to return a result. Aspergillus endocarditis of the mitral valve presents as valvular vegetations that reduce the caliber of the mitral valve and can cause syncope as in the case of mitral stenosis with subsequent valve failure, left atrial enlargement, and prospective cardiovascular failure. Reports of the management of Aspergillus endocarditis after serial mitral valve replacement are not prominent in the literature. We report the case of a 41-year-old female with previous mitral valve prosthesis who received a second prosthetic mitral valve after a syncopal episode. Vegetations resembling thrombi were noted on transesophageal echocardiogram, diagnosed as Aspergillus fumigatus endocarditis, and successfully treated with antifungal therapy in conjunction with removal of her dysfunctional prosthesis.
ABSTRACT
A 53-year-old diabetic male with sternal dehiscence presented with recurrent staphylococcus bacteremia 2years after coronary artery bypass grafting (CABG). He was found to have a giant right coronary artery (RCA) pseudoaneurysm and a coronary cameral fistula on imaging. Due to excessive surgical risk, the patient underwent percutaneous treatment with a 5mm Amplatzer vascular plug 4 (St. Jude Medical, St.Paul, MN). Post-procedure imaging showed successful cessation of flow into the pseudoaneurysm and follow-up CT scan demonstrated significant improvement in the size of the pseudoaneurysm.

OBJECTIVE: To assess the effect of cardiorespiratory fitness on the association between the initiation of statin therapy and incident diabetes. PATIENTS AND METHODS: In a prospective observational study, we studied 6519 generally healthy men and 2334 women with two preventive health examinations from December 15, 1998 through December 18, 2013 which included measurement of fitness levels, statin therapy, risk factors for diabetes, and incident diabetes. RESULTS: 93 cases of incident diabetes occurred during an average follow-up of 3.0 years. After multivariable adjustment, an increased odds of incident diabetes with statin use was observed in those patients with impaired fasting glucose at baseline (odds ratio [OR]: 2.15, [95% CI:1.26 to 3.67]), but not among individuals with normal glucose levels (OR:1.85, [95% CI: 0.76 to 4.52]). Cardiorespiratory fitness attenuated but did not eliminate the increased risk of incident diabetes with statin use. CONCLUSION: In a population of relatively healthy patients, statin use was not associated with incident diabetes in patients with normal fasting glucose at baseline. However, it was associated with incident diabetes in those patients with impaired fasting glucose at baseline, though this risk was substantially reduced by increasing fitness. In addition, increasing cardiorespiratory fitness was inversely associated with incident diabetes whether or not a patient was treated with a statin.
