With great interest I read the article ‘Reduced right ventricular ejection fraction in endurance athletes presenting with ventricular arrhythmias: a quantitative angiographic assessment’ by Ector et al. 1 Even if invasive methods are employed, a thorough evaluation of the morphology and functions of the right ventricle (RV) may be difficult due to the complex geometry and anatomy. Examination of RV geometry in athletes poses an additional puzzle because of the gross changes of both ventricular…

Reduced right ventricular ejection fraction in endurance athletes presenting with ventricular arrhythmias: a quantitative angiographic assessment.
TLDR
VA in high-level endurance athletes frequently originate from a mildly dysfunctional RV, raising the question whether endurance exercise not only acts as a trigger for these arrhythmias but also as promoter of the RV changes.
Right ventricular myocardial performance index and exercise capacity in athletes
TLDR
The right ventricular myocardial performance index showed a negative correlation with maximal oxygen consumption, which may reflect changes inright ventricular function and exercise capacity in athletes.
An echocardiographic study of right and left ventricular adaptation to physical exercise in elite female orienteers.
TLDR
This study suggests symmetrical cardiac enlargement with a concomitant increase in both the right and left ventricular wall, probably reflecting the increased haemodynamic loading in the female athletes.
Biventricular myocardial adaptation to different training protocols in competitive master athletes.
Additional predictive value of both left and right ventricular ejection fractions on long-term survival in idiopathic dilated cardiomyopathy.
TLDR
Right ventricular ejection fraction appears to be a complementary predictor of survival in idiopathic dilated cardiomyopathy, suggesting the importance of assessing right ventricular function in this disease.
Early improvement in left ventricular diastolic function after relief of chronic right ventricular pressure overload.
TLDR
To assess this, the Doppler indexes of left ventricular diastolic function and echocardiographic measures ofleft ventricular volume were analyzed in 22 patients before and within 1 week after pulmonary thromboendarterectomy for chronic thrombolic pulmonary hypertension.
