T he normal pericardium consists of 2 layers: a fibrous outer layer and a serous inner layer. The pericardial space is enclosed within these 2 layers and normally contains 20 to 50 mL of serous fluid. The pericardium serves a variety of functions. In addition to its mechanical effects on the heart (limiting distention, promoting chamber-coupling interaction, maintaining cardiac geometry, enabling frictionless movement, and serving as a barrier to infection), the pericardium has immunologic, vasomotor, paracrine, and fibrinolytic activities.
A 65-year-old patient underwent double coronary artery bypass grafting using the left internal thoracic artery on the left anterior descending coronary artery and nitinol alloy mesh [external Saphenous Vein Support (eSVS)]–covered saphenous vein graft to the right posterior descending coronary artery. Transit-time flow measurements (TTFMs) were obtained on meshed and bare parts of the vein graft. There was no difference in TTFM parameters (flow, pulsatility index, and diastolic fraction values) obtained from the eSVS mesh-covered and the uncovered parts of the venous graft. This observation confirms that eSVS mesh does not interfere with TTFM on venous coronary bypass conduits.
Background/Introduction In order to develop a new surgical program based on recently developed technologies, companies often require a minimal volume of operations. Sutureless aortic bioprostheses were recently introduced in order to make the operation simpler, faster and more user friendly. Aims/Objectives The aim of this study is to review our results with the Edwards Intuity Elite sutureless bioprosthetic aortic valve.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
