Abstract

Abstract Papillary fibroelastomas are rare primary tumours of cardiac origin accounting for approximately 10% of all primary cardiac neoplasms. Due to a high thromboembolic risk, surgical excision is the mainstay of treatment in these patients and median sternotomy the most widely used approach. We describe the case of a 43 year-old lady presenting with acute myocardial infarction secondary to aortic valve papillary fibroelastoma subsequently excised using a minimal access technique. From our experience mini-sternotomy offers excellent exposure and allows for safe resection in such cases, improving cosmesis without compromising either intra or post-operative outcome.

Abstract

Abstract Cor triatriatum is a rare congenital cardiac malformation and it usually refers to the left atrium. We report an unusual case of cor triatriatum in a 33 - year old woman presented with congestive heart failure caused by left ventricular systolic dysfunction.

32. Frozen Elephant Trunk: A technique which can be offered in complex pathology to fix the whole aorta in one setting

Abstract

Abstract We report a case of treating complex aortic pathology with the use of the Frozen Elephant Trunk technique in a patient with chronic type B aortic dissecting aneurysm associated with arch and ascending aorta dilatation, proximal aortic disease and coronary disease. The case was further complicated due to the involvement of the abdominal vessels and preexisting femoral to femoral crossover bypass. In addition the patient had a tracheostomy for laryngeal cancer. We emphasize the role of the Frozen Elephant Trunk to fix the whole aorta in one setting with special attention given to the changes taking place in vascular perfusion following correction and reconstitution of the true lumen.

33. Skeletonization of radial and gastroepiploic conduits in coronary artery bypass surgery

Abstract

Abstract The use of a skeletonized internal thoracic artery in coronary artery bypass graft surgery has been shown to confer certain advantages over a traditional pedicled technique, particularly in certain patient groups. Recent reports indicate that radial and gastroepiploic arteries can also be harvested using a skeletonized technique. The aim of this study is to systematically review the available evidence regarding the use of skeletonized radial and gastroepiploic arteries within coronary artery bypass surgery, focusing specifically on it's effect on conduit length and flow, levels of endothelial damage, graft patency and clinical outcome. Four electronic databases were systematically searched for studies reporting the utilisation of the skeletonization technique within coronary revascularisation surgery in humans. Reference lists of all identified studies were checked for any missing publications. There appears to be some evidence that skeletonization may improve angiographic patency, when compared with pedicled vessels in the short to mid-term. We have found no suggestion of increased complication rates or increased operating time. Skeletonization may increase the length of the conduit, and the number of sequential graft sites, but no clear clinical benefits are apparent. Our study suggests that there is not enough high quality or consistent evidence to currently advocate the application of this technique to radial or gastroepiploic conduits ahead of a traditional pedicled technique.

34. Debranching-first and proximal arch replacement for an innominate artery aneurysm: a case study.

Abstract

The aneurysms of the innominate artery represent a rare form of aneurysmal disease. Management in an early elective basis is recommended due to the risk of stroke and rupture. Treatment options include open surgery, which is the gold standard, and endovascular repair. We describe the debranching-first technique and proximal arch replacement for a huge innominate artery aneurysm and discuss the surgical strategy for cannulation, perfusion and organ protection.

Abstract

Postoperative hemorrhage is a common complication in cardiac surgery, and it is associated with a considerable increase in morbidity, mortality, and cost. Recombinant activated factor VII (rFVIIa) is an emerging hemostatic agent, increasingly used in cardiac surgery. This article systematically reviews the evidence regarding the efficacy, safety, and cost of rFVIIa in this setting. Although definitive evidence from randomized controlled trials is lacking, the use of rFVIIa in patients experiencing refractory postoperative hemorrhage seems promising and relatively safe. However further research is required to definitively establish its clinical utility in the postoperative cardiac patient.

Abstract

A solitary papilloma versus the usual multiple lesions of papillomatosis is extremely rare. Even more infrequent is a solitary papilloma of the trachea in an adult patient. In the present report, a case of a solitary papilloma in the distal trachea is presented. After two unsuccessful sessions of laser ablation, resection of the lower one-third of the trachea was performed through a right posterolateral thoracotomy. Postoperative histology results disclosed a malignant degeneration into squamous cell carcinoma. The patient had an excellent outcome after resection of the affected portion of the trachea. There was no evidence of recurrence after 20 months of follow-up.
