What are adverse effects of the Senning and Mustard repairs?
Although short-term survival from the procedures rose to 95%, long-term survival was complicated by SVC and pulmonary vein stenosis, baffle leak, tricuspid regurgitation, right ventricular failure, and arrhythmia.
Coronal view of the same case. Typically in transposition, systemic deoxygenated blood flows toward the tricuspid valve, enters the right ventricle, and then is sent out through the transposed aorta; oxygenated blood enters the left atrium, enters the left ventricle, and then is sent out the main pulmonary artery. The systemic and pulmonary circulations are separate.
With the Senning repair, systemic deoxygenated blood flow is redirected to the mitral valve --> left ventricle --> main pulmonary artery.
