BACKGROUND Identification of the infarct-related artery (IRA) in patients with STEMI using coronary angiography (CA) is often based on the ECG and can be challenging in patients with severe multi-vessel disease. The current study aimed to determine how often percutaneous intervention (PCI) is performed in a coronary artery different from the artery supplying the territory of acute infarction on...

BACKGROUND Recent studies using stress-rest perfusion cardiovascular magnetic resonance (CMR) demonstrated a close correlation between myocardial ischemia and reduced fractional flow reserve (FFR). However, its diagnostic concordance may be reduced in patients with multivessel disease. We sought to evaluate the concordance of adenosine stress-rest perfusion CMR for predicting reduced FFR, and t...

BACKGROUND Cardiac catheterization is routinely used as a diagnostic tool in single ventricle patients with superior cavopulmonary connection. This physiology presents inherent challenges in applying the Fick principle to estimate flow. We sought to quantitatively define the error in oximetry-derived flow parameters using phase-contrast cardiac MRI (CMR) as a reference. METHODS AND RESULTS Th...

Introduction Interventional CMR has been undergoing rapid development because of the availability of MR compatible interventional catheters, and the increased performance of the MR systems themselves. Much of this development has benefited from the previous groundbreaking work in MRI guided surgical technologies ; however, intravascular techniques do not carry the requirement for an open access...

Background Cardiac Magnetic Resonance (CMR) provides superior assessment of right ventricle (RV) function and assessment of multiple physiologic parameters with high interand intraobserver reproducibility thus providing a noninvasive assessment of pulmonary arterial hypertension (PAH) by evaluating RV physiologic parameters. CMR also provides a unique noninvasive assessment of myocardial fibros...

Background Volume flow analysis is essential in the assessment of many cardiovascular diseases such as valvular regurgitation, intra-cardiac shunt, and complex congenital heart diseases. Clinically, CMR-based volume flow analysis is performed using 2D flow CMR. This requires user-dependent and time-consuming positioning of 2D planes in each vessel while the patient is still in the scanner. Prev...

Methods Performed stress CMR for 80 patients referred for ischemia assessment after Invasive Coronary angiogram. CMR examination included are Cine Cardiac function , Adenosine stress Perfusion, Rest Perfusion and late Gadolinium enhancement with appropriate sequences. Follow up done for these Patients for a period of one year after CMR study for occurrence of Major adverse cardiac events (MACE ...

Background First pass myocardial perfusion imaging by CMR may permit the detection of myocardial ischaemia with greater accuracy than single photon emission computed tomography (SPECT). Technical developments have led to improvements in myocardial perfusion CMR, particularly through accelerated data acquisition methods. These permit the acquisition of data at higher spatial resolution than conv...

Cardiovascular MR (CMR) has an emerging role in the noninvasive diagnostic assessment of heart failure (HF). Different imaging sequences allow for a detailed assessment of cardiac morphology, function, myocardial perfusion, tissue characterization, and blood flow measurement. This article reviews the key applications of CMR in HF, with special focus on how CMR may influence the diagnostic and t...

Background Training of cardiovascular magnetic resonance (CMR) is an important topic in times of growing acceptance of the method for accurate diagnosis and management of cardiovascular disease. However, off-site trainings are becoming less acceptable with increasing cost and time pressure. Here we introduce a novel CMR network, capable of partially remote CMR training and continuous remote exp...
