Abstract
Cine DENSE (Displacement Encoding with Stimulated Echoes) MRI offers high resolution circumferential, radial, and longitudinal strain assessment. Dyssynchrony assessment using midwall circumferential strain corresponds to the predominant physiologic orientation of myofibers, and its effectiveness for cardiac resynchronization therapy (CRT) patient selection has recently been demonstrated [1]. Current echocardiographic dyssynchrony measures are based on radial or longitudinal velocity/strain.
Highlights
Prophylactic implantation of a cardioverter/ defibrillator (ICD) has been shown to reduce mortality in patients with chronic myocardial infarction (CMI) and an increased risk for life threatening ventricular arrhythmia (VA)
We reported non-sustained ventricular tachycardias (NSVT) (n = 1), VF (n = 1) during dobutamine infusion, as well as overt heart failure (n = 2) and unstable angina (n = 1) related to adenosine stress cardiac magnetic resonance (CMR)
Compared to Whites, Hispanics were at a higher risk for diastolic dysfunction, Chinese ethnicity showed a relative protective effect after adjusting for all other risk factors
Summary
Prophylactic implantation of a cardioverter/ defibrillator (ICD) has been shown to reduce mortality in patients with chronic myocardial infarction (CMI) and an increased risk for life threatening ventricular arrhythmia (VA). Methods: In 11 patients (age 0.7 – 27 years) with complex congenital heart disease, surgical questions were directed towards palliative or corrective surgery but consensus about the optimum treatment strategy was not reached using standard diagnostic tools including echocardiography, catheterization and conventional magnetic resonance imaging (MRI). In these patients, three-dimensional printed cast and virtual computer models of the heart were made on the basis of high-resolution whole-heart and/or cineMRI.
