Comparative StudyComparison of reduction ascending aortoplasty and ascending aortic replacement for bicuspid valve related aortopathy in young adult patients undergoing aortic valve replacement--long-term follow-up.
We aimed to determine the long-term outcomes of reduction ascending aortoplasty and ascending aortic replacement. A secondary aim was to document our experience with the long-term "growth" of woven Dacron grafts. ⋯ We have demonstrated satisfactory long-term outcomes with both RAA and AAR in patients with BAV related aortopathy who have undergone the Ross procedure. We have noted a greater diameter reduction with AAR when compared with RAA over nine years. In this series, "growth" of the woven Dacron grafts occurred, however individual measures did not correlate with other studies.

Mitral valve repair offers superior long-term survival, freedom from cardiac morbidity, and quality of life in patients with severe mitral regurgitation compared to medical management and mitral valve replacement; it is the treatment of choice in these patients. Mitral valve repair is the only treatment that restores normal life expectancy to otherwise healthy patients with advanced degenerative mitral valve disease. This review focuses on indications, timing and techniques for mitral valve repair in degenerative disease, emphasising the importance of anatomy in surgical outcomes.

Simplified cerebral protection using unilateral antegrade cerebral perfusion and moderate hypothermic circulatory arrest.
Antegrade cerebral perfusion is one of the most reliable methods of organ protection during hypothermic circulatory arrest for aortic arch surgery. We used a simplified antegrade cerebral perfusion technique with low mortality and morbidity. ⋯ The mortality and neurological outcomes of aortic surgery using unilateral antegrade cerebral perfusion with moderate hypothermic circulatory arrest produced satisfactory results. Bilateral cannulation and deep hypothermia appear to be unnecessary in most cases. The coagulopathy from deep hypothermia is thereby avoided.
