Tomographic left ventricular volume determination in the presence of aneurysm by three-dimensional echocardiographic imaging. I: Asymmetric model hea…
1996
To improve the accuracy of measurements of left ventricular volume in the presence of an aneurysm, we used three-dimensional echocardiographic imaging to analyze the shape of left ventricles in 23 asymmetric model hearts with eccentric aneurysms of different sizes, shapes, and localizations. A standard 3.75 MHz ultrasound probe with a rotation motor device was used to obtain a three-dimensional data set. By rotating the probe stepwise 1 degree, 180 radial ultrasound pictures were digitized. On the basis of the three-dimensional data set, the following parameters were determined and compared with the dimensions of the model hearts obtained by direct measurement: total left ventricular volume…
Special Article - Exercise-induced right ventricular injury or arrhythmogenic cardiomyopathy (ACM): The bright side and the dark side of the moon.
2020
There is still debate on the range of normal physiologic changes of the right ventricle or ventricular (RV) function in athletes. Genetic links to arrhythmogenic cardiomyopathy (ACM) are well-established. There is no current consensus on the importance of extensive exercise and exercise-induced injury to the RV. During the intensive exercise of endurance sports, the cardiac structures adapt to athletic load over time. Some athletes develop RV cardiomyopathy possibly caused by genetic predisposition, whilst others develop arrhythmias from the RV. Endurance sports lead to increased volume and pressure load in both ventricles and increased myocardial mass. The extent of volume increase and cha…
Atrial fibrillation in highly trained endurance athletes — Description of a syndrome
2016
Atrial fibrillation (AF) is the most common heart arrhythmia, the risk of which typically increases with age. This condition is commonly associated with major cardiovascular diseases and structural heart damage, while it is rarely observed in healthy young people. However, increasing evidence indicates that paroxysmal AF can also onset in young or middle-aged and otherwise healthy endurance athletes (e.g., cyclists, runners and cross-country skiers). Here we review the topic of AF associated with strenuous endurance exercise (SEE), for example cycling, running and cross-country skiing, especially at a competitive level, and we propose the definition of a new syndrome based on the accumulati…
