Background/Introduction A patent left internal mammary artery (LIMA) graft challenges the protective effects of cold blood cardioplegia in patients undergoing re-operative aortic valve replacement (AVR). Aims/Objectives This study presents the results of our approach to myocardial protection in a series of consecutive patients with previous coronary artery bypass (CAB) undergoing AVR.
Coarctation of aorta is strongly asssociated with bicuspid aortic valves. This is a risk factor for infective endocarditis. Aneurysm of a sinus of Valsalva is a rare defect with a prevalence of 0.09% and is associated in 10% of cases with bicuspid aortic valves and less frequently with coarctation of aorta and atrial septal defect. The association of coarctation of aorta with an atrial septal defect is rare. This is the first case reported in Puerto Rico of an adult patient with coarctation of aorta in association with a ruptured aneurysm of a sinus of Valsalva and an atrial septal defect. The patient is a 22 year old male with coarctation of aorta diagnosed since childhood, who was admitted at the Cardiovascular Center of Puerto Rico due to infective endocarditis secondary to teeth infection (caused by Streptococcus mitis) and signs of congestive heart failure. Upon evaluation with transthoracic and transesophageal echocardiograms, he was found to have coarctation of aorta in aortic isthmus, aortic root dilatation, bicuspid aortic valve with vegetation, severe aortic and tricuspid regurgitation, aneurysm of non coronary sinus of Valsalva with perforation to right atrium, biatrial enlargement and dilated right ventricle. Successful antibiotherapy of endocarditis was achieved. Afterwards, surgical replacement of aortic valve and ascending aorta and closure of non coronary sinus of Valsalva aneurysm was done. A secundum atrial septal defect was found and was also closed. Color photographic registration of the findings confirmed at surgery was obtained. Surgical correction of coarctation of aorta was postponed for a future time. The patient had a successful postsurgical recovery and was discharged home with anticoagulation treatment.
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.
