A 44-year-old fit and active female was referred by her general practitioner with palpitations, mostly occurring at rest. Electrocardiography performed in the community demonstrated sudden onset of an atrial tachycardia of 115 beats per min. When assessed in hospital, she was asymptomatic with a blood pressure of 110/62 and a regular pulse rate of 50 beats per min. Resting electrocardiography revealed sinus rhythm with poor R wave progression with no evidence of left ventricular hypertrophy or ischemia. A 24-h electrocardiography demonstrated four beats of atrial tachycardia.\nA transthoracic echocardiogram demonstrated a prominent coronary sinus, moderate mitral regurgitation, and a bicuspid aortic valve []. Transesophageal echocardiography showed normal biventricular systolic function, left atrial dilatation, mild to moderate mitral regurgitation, and tricuspid regurgitation. The aortic valve was bicuspid with trivial aortic regurgitation but no significant stenosis. The ascending aorta was dilated for her age and body surface area, with a maximum diameter of 4.0 cm. There was no evidence of aortic coarctation or dissection.\nSaline contrast echocardiography was performed via the left and right arms [], [], [] and []. This confirmed PLSVC with no obvious shunt. Cardiac magnetic resonance imaging (MRI) demonstrated bicuspid aortic valve with dilated aortic root. A PLSVC was seen draining into the coronary sinus and then the right atrium. A separate right-sided non-hypoplastic superior vena cava also emptied into the right atrium. It was noted that a left-sided IVC drained into the coronary sinus and right atrium. Three hepatic veins were seen emptying into a short right-sided IVC, again draining into the right atrium.
We present a case of a 54 years old male who initially presented with one month history of worsening epigastric pain and vomiting. He was referred to our care after an ultrasound and CT abdomen showing dilated common bile duct up to 13mm with no obvious intraductal obstruction. An incidental type 1 duplicated IVC was demonstrated on the CT abdomen (Figure and 2).\nNo intra-abdominal mass or lymphadenopathy were detected. Notably, he is a known BRCA2 mutation carrier. Both, his mother and sister had BRCA2-positive breast cancer. One of his great uncles also had male breast cancer. The patient was clinically jaundiced on presentation, with a bilirubin of 106. His other liver function tests were ALT at 465, GGT at 1032 and at ALP 271. His tumour markers CA-125 and CA-199 were 12 and 94 respectively.\nThe patient was subsequently found to be hypotensive and tachycardic with a new drop in haemoglobin from 100 to 72 during his stay. An urgent gastroscopy then revealed a 10mm punched-out ulcer with adherent clot at the ampulla. The lesion was partially obstructed and no active bleeding was seen. Histology on biopsy showed moderately differentiated adenocarcinoma. CT angiography was then performed. No active extravasation was seen and the gastroduodenal artery was empirically embolised with microcoils. An apparent cavitation at the medial aspect of the second part of duodenum was now identified on the CT imaging (Figure ). No metastasis was seen on staging CT imaging.\nA whipple procedure was performed. The duplicated right IVC was visualised intraoperatively with mobilisation of the uncinate process but appeared relatively normal. The left sided IVC was not encountered. No major complications were reported during his inpatient stay. Patient was discharged home and subsequently commenced on adjuvant therapy.
