ABSTRACT The key diagnostic criterion for hypertrophic cardiomyopathy is the presence of otherwise unexplained hypertrophy. Current definitions of HCM rely on specific thresholds to establish a diagnosis, while guideline directed risk stratification algorithms take its magnitude into consideration.

ABSTRACT Purpose To develop a denoising technique for displacement encoding with stimulated echoes (DENSE) MRI that improves spatial resolution, efficiency, and accuracy, and enhances accessibility by implementing DENSE MRI at 0.55 T. Methods We developed a low‐rank denoising technique, which leverages multidimensional spiral cine DENSE MRI data for ...

ABSTRACT Purpose This study aimed to improve the analysis of the left ventricular (LV) blood pool hyperpolarized [1‐13C]pyruvate signal for a more reliable quantification of downstream metabolic outcome. Methods Hyperpolarized [1‐13C]pyruvate magnetic resonance spectroscopic images were acquired dynamically at 3 Tesla in 106 participants (NCT03685175).

Abstract Aims Patients with myocardial infarction with non‐obstructive coronary arteries (MINOCA) may be affected by coronary microvascular dysfunction with reduced stress perfusion. Changes in native T1 and T2 reflect changes in myocardial perfusion; therefore, the aim of our study was to investigate whether non‐contrast, adenosine stress native T1 ...

Non‐invasive pressure–volume loop analysis in left ventricular load manipulation
Abstract Background Clinical monitoring of patients with heart failure or cardiomyopathy is facilitated by detailed assessment of cardiac loading conditions. Specifically, alterations in preload and afterload may unmask pathology through effects on ventricular pressure–volume (PV) relations. Therefore, the aim was to assess non‐invasive PV loops during

Myocardial perfusion reserve is low in heart transplant patients and is related to exercise capacity
Abstract Aims Heart transplant (HTx) patients are known to be at risk of coronary microvascular dysfunction as well as having decreased exercise capacity. The aim of this study was to investigate if microvascular function in HTx patients differs from healthy controls and is related to objective measures of exercise capacity.
