Introduction:  In patients who underwent surgery to repair Tetralogy of Fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest. Hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. The aim of present study was to assess the effects of pulmonary valve replacement on rig...

Abstract Cardiac sympathetic activity plays a key role in supporting cardiac function both health and disease conditions, nuclear imaging has always represented the only way for non-invasive evaluation of functional integrity terminals, mainly through use radiopharmaceuticals that are analogues norepinephrine and, particular, with 123I-mIBG imaging. This technique demonstrates presence dysfunct...

Magnetic Resonance Spectroscopy is the only non invasive method, not involving exposure to radiation, that allows study of the cardiac metabolism, without the use of a tracer. In the past, most studies of cardiac metabolism were performed with spectroscopy, in different cardiac scenarios (ischemic cardiac diseases, heart failure, for example). This technique should be useful to evaluate and mon...

Otavio R. Coelho-Filho, MD, MPH Carsten Rickers, MD Raymond Y. Kwong, MD, MPH Michael Jerosch-Herold, PhD Contrast material–enhanced myocardial perfusion imaging by using cardiac magnetic resonance (MR) imaging has, during the past decade, evolved into an accurate technique for diagnosing coronary artery disease, with excellent prognostic value. Advantages such as high spatial resolution; absen...

Cardiovascular disease is a leading cause of morbidity and mortality globally. Early diagnostic markers are gaining popularity for better patient care disease outcomes. There is an increasing interest in noninvasive cardiac imaging biomarkers to diagnose subclinical cardiac disease. Feature tracking cardiac magnetic resonance imaging is a novel post-processing technique that is increasingly bei...

assessment of cardiac right‑ventricle functions plays an essential role in diagnosis of arrhythmogenic right ventricular dysplasia (arvd). among clinical tests, cardiac magnetic resonance imaging (mri) is now becoming the most valid imaging technique to diagnose arvd. fatty infiltration of the right ventricular free wall can be visible on cardiac mri. finding right‑ventricle functional paramete...

The clinical applications of cardiovascular magnetic resonance imaging with contrast enhancement are expanding. Besides the direct visualisation of viable and non-viable myocardium, this technique is increasingly used in a variety of cardiac disorders to determine the exact aetiology, guide proper treatment, and predict outcome and prognosis. In this review, we discuss the value of cardiovascul...

Because of the enormous economic and social impact of cardiovascular disease in the United States, there is a need for improved noninvasive diagnosis. Cardiac MR imaging is a versatile, comprehensive technique for assessing cardiac morphology and function. With an understanding of cardiac anatomy and physiology as well as MR physical principles, cardiac MR imaging can be performed and play an i...

A motion artifact suppression technique (MAST) has recently been developed that significantly reduces motion artifacts in conventional 2DFT imaging. The technique utilizes modifications of slice-select and read gradient waveforms to eliminate velocity, acceleration, and pulsatility phase shifts that occur between the 90 degrees pulse and data collection. T2-weighted cranial MAST images were rat...

introduction heart failure is the second most common cause of ascites after cirrhosis. there are cardiac and noncardiac etiologies of ascites, and the multimodality imaging approach is a rich tool to redefine the final diagnosis. case presentation we present a case-series where 3 patients were referred to our hospital for further hepatology assessment due to severe abdominal ascites and liver f...
