Background: 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.
Case summary: 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.
Discussion: 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.
