Abstract: Background—To use cardiovascular magnetic resonance to investigate left ventricular wall thickness and the presence of asymmetrical hypertrophy in young army recruits before and after a period of intense exercise training. Methods and Results—Using cardiovascular magnetic resonance, the left ventricular wall thickness was measured in all 17 segments and a normal range was calculated for each. The prevalence of asymmetrical wall thickening was assessed before and after training and defined by a ventricular wall thickness ≥13.0 mm that was >1.5× the thickness of the opposing myocardial segment. Five hundred forty-one men (mean age, 20±2 years) were recruited, 309 underwent repeat scanning. Considerable variation in wall thickness was observed across the ventricle with progressive thickening on moving from the apex to base (P<0.001) and in the basal and midcavity septum compared with the lateral wall (11.0±1.4 versus 10.1±1.3 mm; P<0.001). Twenty-three percent had a maximal wall thickness ≥13.0 mm, whereas t...

Primer on Pulsed Electrical Field Ablation: Understanding the Benefits and Limitations.
TL;DR: In this article, the key aspects that need to be considered for safe and effective PEF delivery are reviewed, and their impact on clinical feasibility is discussed, and the most important benefit of PEF appears to be the ability to kill cells through mechanisms that do not alter stromal proteins, sparing sensitive structures to improve safety, without sacrificing cardiomyocyte ablation efficacy.

TL;DR: In this article, the authors aimed to test whether pathological LVH, such as occurs in hypertrophic cardiomyopathy (HCM), hypertensive heart disease, or aortic stenosis, and physiological LVH in athletes, can be distinguished by means of left ventricular volume and geometric indices, derived from cardiovascular magnetic resonance imaging.

Reduction in Sample Size for Studies of Remodeling in Heart Failure by the Use of Cardiovascular Magnetic Resonance
TL;DR: The calculated sample sizes in patients with HF for CMR to detect a 10-ml change in end-diastolic volume and end-systolic volume were substantially smaller than recently published values for two-dimensional echocardiography (reduction of 81-97%).
