Continuous Heart Murmur-Two Cases of Rare Causes and Role of Imaging in Diagnosis

Janice JK Ip, Peter KT Hui, Sonia HY Lam and Stephen SC Cheung

 A continuous murmur is defined as a murmur that begins in systole, continues through the second heart sound and into part or all of diastole. Among a number of differential diagnoses, anomalous systemic arterial supply to the normal basal segments and Rupture of Sinus of Valsalva (RSOV) are two rare causes of continuous heart. These two entities, which are often overlooked clinically, may have potentially fatal complications. We herein present two cases of uncommon causes of continuous heart murmur; demonstrate the radiological features and corroborate the role of Electric Cardiogram-Gated Computed Tomography (ECG-gated CT) in diagnosis.
