Effect of Adjuvant Chemotherapy on Left Ventricular Remodeling in Women with Newly Diagnosed Primary Breast Cancer: A Pilot Prospective Longitudinal Cardiac Magnetic Resonance Imaging Study.

Purpose: The aim of this study was to assess the left ventricular (LV) remodeling response to chemotherapy in low-cardiac-risk women with newly diagnosed nonmetastatic breast cancer. Cardiotoxic effects of chemotherapy are an increasing concern. To effectively interpret cardiac imaging studies performed for screening purposes in patients undergoing cancer therapy it is necessary to understand the normal changes in structure and function that may occur.

Severe and resistant hypertension in an older woman with claudication.

Coarctation of the aorta is an uncommon cause of treatment-resistant hypertension in adults. It is typically detected and treated in infancy or childhood with surgical or endovascular procedures. Most cases of recurrence of coarctation after repair occur in childhood or early adulthood; recurrence in older persons (>70 years) has rarely been reported.

Apical hypertrophic cardiomyopathy associated with chronic hypertension: diagnostic and management implications.

Apical hypertrophic cardiomyopathy (HCM) is a rare variant of HCM in the non-Japanese population (1% to 2%). Diagnostic dilemma occurs when this type of HCM is newly discovered in a patient previously diagnosed with left ventricular hypertrophy (LVH) secondary to hypertension. We describe an atypical presentation of an apical HCM in the setting of chronic hypertension (HTN) and review the literature of this rare variant of HCM.

Effect of in utero exposure of iodinated intravenous contrast on neonatal thyroid function.

Purpose: Administration of radioactive iodine to a pregnant woman for thyroid ablation has been shown to affect neonatal thyroid levels. Thus, there is a theoretical risk in affecting a neonate's thyroid level upon birth with prior administration of intravenous contrast containing iodine to a pregnant woman during a computed tomographic scan. However, there is no literature to support this theoretical risk.

Head and neck cancers: post-therapy changes in muscles with FDG PET-CT.

Background: FDG PET-CT plays a critical role in the management of head and neck cancer patients. After therapy, many patterns of altered physiologic FDG uptake have been recognized. In our institution, we noticed patterns of head and neck muscle uptake that were unique in the post-therapy scans of head and neck cancer patients.
