Purpose: The influence of MRI-conditional cardiac pacemakers on the quality and interpretability of images acquired in cardiac MRI (CMR) examinations was retrospectively investigated. Materials and methods: The subjects in this study were 12 patients (7 men and 5 women, mean age: 68.4 +/- 8.7 years) with MRI-conditional cardiac pacemakers who underwent CMR examinations at our institution between July 2013 and December 2014....
An Unlikely Cause of Atrial Fibrillation-Induced Cardiomyopathy: Phentermine, A Diet pill

Article Type: Case Report | First Published: April 19, 2015
We present a case of an unusual cause of atrial fibrillation-induced cardiomyopathy, which is a diet pill, known as phentermine. This medication used for weight loss and can function as a stimulant is intended for short-term use but when taken for an extensive period of time can become a significant risk factor for developing arrhythmias such as atrial fibrillation....

Takotsubo Cardiomyopathy (TCMP), also known as apical ballooning syndrome or stress induced cardiomyopathy, is characterized by left ventricular mid and/or apical wall motion abnormality in the absence of obstructive coronary artery disease. TCMP is a disorder of left ventricular myocardial contractility, and rarely associated with serious cardiac conduction abnormalities....

Functional Mitral Regurgitation Tenting Area is Directly Related to Non-Ischemic Cadiomyopathy

Article Type: Letter to the Editor | First Published: March 22, 2015
I have read with great interest the article by Kammoun et al., and I congratulate them for this paper. Functional mitral regurgitation (MR) is a very hard-to-treat illness, because it is not a disease itself but just the final result of an impaired and/or geometrically distorted left ventricle. Agricola et al. have described in a fie way the high impact played by the tethering mechanism of the posterior mitral complex in this kind of patients....

The aim of this study was to evaluate the improvement in hemodynamic, metabolic, and ventilatory response during exercise along with the improvement of anemia with EPO treatment in anemic hemodialysis patients. Methods: Thirty-seven hemodialysis patients with anemia (48.8 +/- 13.6 years) received EPO (1500 or 3000 unit, 3 times a week). Parameters measured prospectively before and after EPO treatment included hemoglobin, cardiac output by dye dilution method, echocardiography, and cardiopulmonar...
