Mid wall fibrosis on CMR with late gadolinium enhancement may predict prognosis for LVAD and transplantation risk in patients with newly diagnosed dilated cardiomyopathy-preliminary observations from a high-volume transplant centre.

Background: Patients with newly diagnosed dilated cardiomyopathy (DCM) and advanced heart failure have a very high morbidity and mortality with an unpredictable clinical course. We investigated the role of cardiovascular magnetic resonance (CMR) imaging using late gadolinium enhancement (LGE) in this cohort of high-risk patients. We hypothesized that LGE has high prognostic value in primary DCM patients referred for possible transplantation/left ventricular assist device (LVAD) consideration.

Is there an alternative explanation to post-myocardial infarction emergence of mitral regurgitation? A CMR-LGE observational study.

Background And Aim Of The Study: Post-myocardial infarction (MI) mitral regurgitation (MR) is thought to be due to a passive, rather than active, remodeling of the mitral valve apparatus and its relationship with other cardiac structures that contribute to MR. Standard contrast-enhanced magnetic resonance (CMR) late gadolinium enhancement (LGE) may be sensitive to non-myocardial pathology involving the mitral valve leaflets. It was hypothesized that the presence of mitral valve enhancement (MVE) on LGE imaging in post-MI patients would be associated with an increased incidence of MR.

Left Ventricular Energy Model Predicts Adverse Events in Women With Suspected Myocardial Ischemia: Results From The NHLBI-Sponsored Women's Ischemia Syndrome Evaluation (WISE) Study.

Objectives: To assess the prognostic value of a left ventricular energy-model in women with suspected myocardial ischemia.

Background: The prognostic value of internal energy utilization (IEU) of the left ventricle in women with suspected myocardial ischemia is unknown.

Methods: Women (n=227, mean age 59±12 years, range 31-86), with symptoms of myocardial ischemia, underwent myocardial perfusion imaging (MPI) assessment for regional perfusion defects along with measurement of ventricular volumes separately by gated Single Photon Emission Computed Tomography (SPECT) (n= 207) and magnetic resonance imaging (MRI) (n=203).

Anginal symptoms, coronary artery disease, and adverse outcomes in Black and White women: the NHLBI-sponsored Women's Ischemia Syndrome Evaluation (WISE) study.

Background: Black women are less likely to be evaluated and treated for anginal symptoms, despite a higher premature cardiac mortality rate compared to white women. Our objective was to compare angina symptoms in black versus white women regarding (1) angina symptoms characterization; (2) relationship with obstructive coronary artery disease (CAD); and (3) relationship with subsequent mortality.

Methods: A cohort of 466 women (69 black and 397 white) undergoing coronary angiography for suspected ischemia and without prior history of CAD completed symptom checklists.
