# Left ventricular inferior wall congenital diverticula in athletes: a case series and review of the literature

## TL;DR

This case series describes two athletes with rare heart wall anomalies and discusses their diagnosis and management.

## Contribution

The study presents a novel case series of congenital left ventricular diverticula in athletes and emphasizes the need for tailored diagnostic and management strategies.

## Key findings

- Two athletes were diagnosed with left ventricular diverticula through multimodal imaging.
- Periodic follow-up without therapy was sufficient for these cases.
- No specific guidelines exist for managing such anomalies in athletes.

## Abstract

Congenital left ventricular diverticula (LVDs) and aneurysms (LVAs) are rare, developmental, cardiac anomalies, which are often asymptomatic. Sometimes they can cause life-threatening complications like arrhythmias, syncope, embolic events, ventricular wall rupture, valvular regurgitation, congestive heart failure, and various symptoms. Diagnosis is usually made after exclusion of acquired causes, from cardiac or non-cardiac disorders. Specific guidelines for LVD/LVA management are not available and treatment options are guided by different case-by-case clinical presentation and possible complications.

We present a series of two patients with occasional diagnosis of diverticula of the inferior basal left ventricular wall in the context of cardiological evaluations for competitive sport certificate. Symptoms were present at clinical evaluation only in Patient 1, together with electrocardiogram (ECG) abnormality. We performed transthoracic echocardiography as a first-line examination and secondly, we confirmed the diverticula by cardiac magnetic resonance. A maximal stress test and 24 h ECG Holter were also performed.

In our case, in light of the clinical-instrumental findings, periodic medical and echocardiographic follow-up without therapy was established, together with the resumption of sports activities.

Nowadays, no specific recommendations exist in athletes and no studies are available on how regular sport practice can influence natural history of LVD/LVA. The current case series highlights the importance of risk stratification for cardiac events, of a multimodal imaging approach in diagnostic procedure and of a tailored treatment strategy.
