1 Surgical management of the straddling mitral valve in the biventricular heart 
Ryo Aeba, MD, Toshiyuki Katogi, MD, Shigeyuki Takeuchi, MD, Shiaki Kawada, MD  The Annals of Thoracic Surgery  Volume 69, Issue 1, Pages (January 2000) DOI: /S (99)

2 Fig 1 Schematic illustration as seen through the right ventricle in a patient with transposition of the great arteries {S,D,D}, a ventricular septal defect, and left ventricular outflow tract obstruction (patient 2). The ventricular septal defect was immediately below the aortic valve. Note the omitted suture line at the papillary muscle of the straddling mitral valve (left). After the completion of the baffle placement, the support mechanism of the straddling mitral valve was secured between the ventricular septum and the baffle (right). The cranial half of the baffle has been removed, showing the aortic valve. The Annals of Thoracic Surgery  , DOI: ( /S (99) )

3 Fig 2 Schematic illustration as seen through the right ventricle in a patient with transposition of the great arteries {S,D,D}, a ventricular septal defect, and left ventricular outflow tract obstruction (patient 1), showing the aortic valve. Note the large papillary muscle on the right ventricular aspect of the ventricular septum near the crest, and the associated abnormal insertion of the tricuspid valve into the conal septum. It was determined that a biventricular repair would lead to left ventricular outflow obstruction as well as atrioventricular valve dysfunction. A univentricular repair was performed.
