Three-dimensional echocardiography of the athlete's heart: a comparison with cardiac magnetic resonance imaging

The Role of Cardiovascular Magnetic Resonance Imaging in Athletic Individuals-A Narrative Review

Cardiovascular magnetic resonance imaging (MRI) is an advanced cardiac imaging modality that is often required when evaluating athletic individuals. Unrestricted imaging planes, excellent spatial resolution, and a lack of ionising radiation are some of the benefits of this modality. Cardiac MRI has been established as the gold standard imaging modality for morphological assessment, volumetric analysis, and tissue characterisation. Cardiac MRI without any doubt is an excellent diagnostic tool when evaluating athletes with symptoms or those individuals exhibiting equivocal findings at screening. It is also useful for athletes who fall within the grey zone and is especially important among athletes with a suspected or confirmed diagnosis. Cardiac MRI plays a strategic role when adopting a shared decision-making model in athletes with heart disease, tailoring and personalising medical care to the condition and the athlete's wishes. The aim of this review is to provide a comprehensive yet practical overview of the role of cardiac MRI when evaluating athletes in clinic.

Echocardiography in the cardiac assessment of young athletes: a 2025 guideline from the British Society of Echocardiography (endorsed by Cardiac Risk in the Young)

Sudden cardiac death in a young physically active individual or athlete is a rare but tragic event. Pre-participation screening and follow-up investigations are utilised to reduce the risk and occurrence of these events. Echocardiography plays a key role in the cardiac diagnostic pathway and aims to identify underlying inherited or congenital structural cardiac conditions. In 2013 the British Society of Echocardiography and Cardiac Risk in the Young produced a joint guidance document to support echocardiographers in this setting. The document was subsequently updated in 2018, and it is now timely to provide a further update to the guideline drawing on the advances in our knowledge alongside the developments in ultrasound technology within this nuanced area of sports cardiology.

Association of age at first sexual intercourse and lifetime number of sexual partners with cardiovascular diseases: a bi-directional Mendelian randomization study

Background

Limited studies have explored the association between sexual factors [age at first sexual intercourse (AFS) and lifetime number of sexual partners (LNSP)] and cardiovascular diseases (CVDs), leaving the causality inconclusive.

Methods

We performed a bi-directional Mendelian randomization (MR) study to investigate the causality between sexual factors and CVDs, including coronary artery disease, myocardial infarction, atrial fibrillation (AF), heart failure (HF), and ischemic stroke (IS). Single-nucleotide polymorphisms (SNPs) for sexual factors were extracted from the UK Biobank. Statistics for each CVD were derived from two different databases. MR estimates were calculated per outcome database and were combined through meta-analysis. Several complementary sensitivity analyses were also performed.

Results

The primary analysis suggested that AFS was causally associated with the risk of CVDs; the odds ratios (ORs) ranged from 0.686 [95% confidence interval (CI), 0.611-0.770] for HF to 0.798 (95% CI, 0.719-0.886) for AF. However, the association between AFS and IS (OR, 0.844; 95% CI, 0.632-1.126) was not consistent in the meta-analysis after excluding SNPs related to confounders. Moreover, non-significant associations were found between LNSP and CVDs. Reverse direction MR analysis showed that CVDs were not associated with sexual factors.

Conclusions

Genetic evidence suggested that AFS was causally associated with the risk of CVDs except for IS, whereas non-significant association of LNSP with CVDs was detected. Further investigation into AFS could be warranted in preventing the progression of CVDs.

Echocardiography Imaging of the Right Ventricle: Focus on Three-Dimensional Echocardiography

Right ventricular function strongly predicts cardiac death and adverse cardiac events in patients with cardiac diseases. However, the accurate right ventricular assessment by two-dimensional echocardiography is limited due to its complex anatomy, shape, and load dependence. Advances in cardiac imaging and three-dimensional echocardiography provided more reliable information on right ventricular volumes and function without geometrical assumptions. Furthermore, the pathophysiology of right ventricular dysfunction and tricuspid regurgitation is frequently connected. Three-dimensional echocardiography allows a more in-depth structural and functional evaluation of the tricuspid valve. Understanding the anatomy and pathophysiology of the right side of the heart may help in diagnosing and managing the disease by using reliable imaging tools. The present review describes the challenging echocardiographic assessment of the right ventricle and tricuspid valve apparatus in clinical practice with a focus on three-dimensional echocardiography.
