Contribution Of Mitral Valve Atrioventricular Plane Displacement To The Stroke Volume In Patients With Severe Mitral Regurgitation
Introduction: Longitudinal shortening measured as atrioventricular plane displacement (AVPD) represents a piston-like movement of the base of the ventricles toward the apex during the cardiac cycle. Prior studies using echocardiography and cardiac magnetic resonance imaging demonstrated AVPD to account for a large part of the left ventricular (LV) stroke volume (SV) in athletes, healthy controls, and heart failure patients. We sought to validate the use of cardiac computed tomography (CCT) to measure the AVPD and subsequently explore the contribution of the AVPD towards overall LV SV in patients with functional and primary...

Cardiac Magnetic Resonance Imaging Findings Predict Major Adverse Events in Apical Hypertrophic Cardiomyopathy
Conclusions:Within our population of apical HCM patients, the extent of LGE and the presence of an apical aneurysm identified by cardiac MRI were both significant predictors of major adverse clinical events.

Quantitative Analysis of Right Ventricular (RV) Function With Echocardiography in Chronic Heart Failure With No or Mild RV Dysfunction: Comparison With Cardiac Magnetic Resonance Imaging
Conclusions— Echocardiographic RV performance parameters (tricuspid annular plane systolic excursion, systolic longitudinal velocity, tissue strain, and 2D strain) correlated with the MRI-calculated RVEF and overall predicted it. In particular, RV 2D strain and tissue strain were good markers for RV longitudinal motions. These echocardiographic parameters are easily obtained and may give important information about RV function for evaluation and prognostic stratification of patients with heart failure.

Interstitial Fibrosis, Functional Status, and Outcomes in Heart Failure With Preserved Ejection Fraction: Insights From a Prospective Cardiac Magnetic Resonance Imaging Study Magnetic Resonance Imaging
Conclusions— We demonstrate that MOLLI-ECV in HFpEF accurately reflects histological ECV, correlates with markers of disease severity, and is associated with outcome among cardiac magnetic resonance parameters but not after adjustment for important clinical and invasive hemodynamic parameters. Nevertheless, MOLLI-ECV has the potential of becoming an important biomarker in HFpEF.

Pericardial, But Not Hepatic, Fat by CT Is Associated With CV Outcomes and Structure: The Multi-Ethnic Study of Atherosclerosis
Conclusions Pericardial fat is associated with poorer CVD prognosis and LV remodeling, independent of insulin resistance, inflammation, and CT measures of hepatic fat.

MRI findings in patients with acute coronary syndrome and unobstructed coronary arteries.
CONCLUSION: Our study emphasizes the diagnostic utility of timely MRI in patients with ACS and unobstructed coronary arteries. We found a high prevalence of TTS patients, who had poorer outcomes compared with patients with a final diagnosis of AMI or myocarditis. PMID: 30582569 [PubMed - as supplied by publisher]

Comparison of direct stenting with conventional strategy on myocardial impairments in ST-segment elevation myocardial infarction: a cardiac magnetic resonance imaging study
AbstractDirect stenting (DS) without pre-dilatation of the culprit lesion might improve myocardial perfusion and prognosis in patients undergoing percutaneous coronary intervention for ST-elevation myocardial infarction (STEMI); however, some studies report conflicting results. We investigated whether DS provides incremental myocardial benefits over conventional stenting (CS) in STEMI patients based on cardiac magnetic resonance imaging (CMR) measures. Reperfused patients who underwent CMR examinations within 1  week of STEMI onset were selected from a multicenter CMR registry of STEMI (NCT: 03768453). Patients were strat...
