Abstract: Delineation and documentation of anatomy in the presence of significant mass pathology presents a diagnostic challenge. This often necessitates the implementation of more than one imaging modality in order to perform an adequate assessment. We present a three-year old boy with extensive distortion of mediastinal anatomy secondary to pleural metastases from a Wilms tumour. This limited the ability to accurately assess mediastinal anatomy and cardiac function at baseline. Reassessment following initiation of chemotherapy showed a significant reduction in size of metastases with complete resolution of the mediastinal distortion. 2018-07-01T00:00:00Z Prominent crista terminalis in a fetus /library/oar/handle/123456789/41985 Title: Prominent crista terminalis in a fetus Authors: Evong, Yolanda; Warren, Andrew E.; Mohsin, H. Abstract: Background: The crista terminalis is a normal cardiac structure located in the right atrium. It is not usually seen using standard view transthoracic echocardiography techniques, but on occasion, hypertrophy allows for easy visualization of this structure, which can be mistakenly labelled pathologic. Case: We report the first known case of a prominent crista terminalis detected in a fetus. Conclusions: This case confirms the presence of a prominent crista terminalis in a developing fetus, a variant which was exclusively described in the pediatric and adult populations until now. Although a prominent crista terminalis is a benign variant, the correct identification of this structure has important diagnostic implications. This report aims to increase familiarity with the appearance of a prominent crista terminalis on both fetal echocardiography and newborn transthoracic echocardiography in hopes that this will aid in the correct diagnosis of this variant in the future. 2018-07-01T00:00:00Z Back trauma resulting in commotio cordis /library/oar/handle/123456789/33932 Title: Back trauma resulting in commotio cordis Authors: Bugeja, Justine; Dimech, Thea; Borg, Charles; Meilak, Samuel; Sammut, Matthew; Grech, Victor E. Abstract: Commotio cordis (Latin: "agitation of the heart") is a dysrhythmia provoked by praecordial trauma during the early part of cardiac repolarisation. Recorded rhythms include ventricular tachycardia/fibrillation, bradyarrhythmias, idioventricular rhythm, complete heart block and asystole. The quoted fatality rate is 65% even with prompt CPR and defibrillation, and exceeds 80% in the absence of such interventions. Above a certain threshold of trauma/impact, structural cardiac damage may also occur (contusio cordis). 2018-04-01T00:00:00Z Anomalous origin of left coronary artery : an unusual case /library/oar/handle/123456789/33931 Title: Anomalous origin of left coronary artery : an unusual case Authors: Abbas, Umair; Cossor, Waseem Abstract: Anomalies of the coronary arteries are rare but are an important cause of sudden cardiac arrest in young athletes. Sudden cardiac arrest has been reported in patients with congenital anomalies of the coronary arteries. We present a rare case of sudden cardiac arrest caused by anomalous left main coronary artery originating high from the posterior aspect of left sinus of Valsalva with intramural retroaortic segment, associated with bicuspid aortic valve. 2018-04-01T00:00:00Z
