Ray R, Salukhe T, Rubens M, Nicol E. An unusual case of ventricular ectopy in a military pilot. Aviat Space Environ Med 2014; 85:462–5.

Background: Congenital left ventricular diverticula are an uncommon cardiac malformation. Although they may be asymptomatic, their presence is important to note as they are associated with systemic embolization of mural thrombus, valvular regurgitation, heart failure, focal ventricular arrhythmias, and sudden death. Case Report: We describe a case of an asymptomatic pilot with a significant burden of ventricular ectopy. The diagnosis of a large left ventricular diverticulum was made by cardiac CT and confirmed by cardiac magnetic resonance imaging. No specific treatment was warranted; however, regular on-going follow up was required. Discussion: It is important to seek out a structural cause for frequent ventricular ectopy even in the absence of symptoms. Transthoracic echocardiography is not always able to delineate the entire left ventricular cavity and other imaging modalities such as ECG-gated cardiac CT or gated MRI may need to be used in conjunction to permit assessment for the presence of structural heart disease in the whole heart. Aircrew with a high burden of ectopy require regular follow-up for complications such as more malignant dysrhythmias or LV impairment. In some cases, pharmacological or even surgical treatment is warranted, which may have a significant bearing for the future licensing of aircrew.
