Surgical exposure by median sternotomy or posterolateral thoracotomy for giant thoracic aortic aneurysms may not be adequate. In these cases, sternotomy-thoracotomy offers better access for the entire thoracic aorta. A sixty-nine-year-old man presented a sudden...
A seventy-year-old man was referred for management of a saccular aneurysm of the distal aortic arch. His history was relevant for smoking, hypertension and hypercholesterolemia. He initially presented with a...
Aortic root remodelling with external subaortic annuloplasty (CAVIAAR procedure) enables physiological movements of the aortic cusps within three symmetrically reconstructed neosinuses, thus preserving root expansibility with the interleaflet triangles (1)....
Aortic root remodeling with external subaortic annuloplasty (CAVIAAR procedure) enables physiological movements of the aortic cusps within three symmetrically reconstructed neosinuses, thus preserving root expansibility with the interleaflet triangles (1)....
Valve sparing root replacement requires meticulous surgical techniques to restore aortic valve function. Several methods have been used to assess aortic valve competency post reconstruction, including visual inspection, water injection,...
The Bentall procedure is a cardiac surgical operation involving composite graft replacement of the aortic valve, aortic root, and ascending aorta, with reimplantation of the coronary arteries into the graft....
An important goal in modern cardiovascular and thoracic surgery is reducing surgical trauma to achieve faster recovery for patients. More surgeons are comfortable with aortic valve replacement via upper hemi-sternotomy...
This video demonstrates one way to arrest the heart in a mini-access aortic root replacement procedure. The method described is suitable for patients with aortic regurgitation. The 5 cm incision...
Redo median sternotomy, total arch replacement, and the frozen elephant trunk procedures for chronic aortic dissection comprise a complex operation. In this video, Professor Yan first explains his operative approach....
An eighty-four-year-old woman presented with acute type A aortic dissection and blood in the pericardial sac. The dissection was contained by the visceral pericardial layer (i.e. the last line of...
This video demonstrates how the surgical team managed to save an elderly woman who presented initially with tamponade and contained aortic rupture, but subsequently developed frank aortic rupture. The patient...
The visceral pericardium covers the heart and the great vessels. It is mentioned in embryology textbooks, but it is rarely described in surgical textbooks. It is a distinct layer that...
The visceral pericardium is a defined layer of connective tissue that covers the heart and the great vessels. It provides additional strength to the ascending aorta and can be regarded...
