The Sano Trial: Treatment Recommendations
I cannot provide treatment recommendations based on "the Sano trial" for managing heart failure or coronary artery disease, as the Sano shunt is a pediatric cardiac surgical procedure for hypoplastic left heart syndrome, not a treatment trial for adult heart failure or coronary artery disease 1.
What the Sano Shunt Actually Is
The Sano shunt is a surgical modification of the Norwood procedure used in infants with hypoplastic left heart syndrome 1. It involves:
- Construction of a right ventricle-to-pulmonary artery (RV-PA) conduit as an alternative source of pulmonary blood flow in newborns with single ventricle physiology 1
- Comparison to the modified Blalock-Taussig (mBT) shunt as an alternative surgical approach 1
Evidence on Ventricular Performance After Sano Shunt
The available evidence addresses concerns about ventriculotomy effects on single ventricle performance:
- No echocardiographic or clinical outcome studies showed poor ventricular performance after ventriculotomy for Sano shunt construction in the short- and medium-term 1
- One small autopsy study (n=11) suggested greater myocardial extracellular matrix remodeling in patients with RV-PA conduit, with potential implications for future ventricular dysfunction 1
- All existing studies are limited by small sample sizes, non-randomized design, retrospective nature, and failure to correlate echocardiographic indices with clinical outcomes 1
Critical Limitation
This is a congenital heart surgery question, not an adult heart failure or coronary disease management question. The evidence provided does not support treatment recommendations for adult cardiovascular conditions 1.
If you are seeking recommendations for adult heart failure or coronary artery disease management, please clarify the specific clinical scenario, as the guidelines provided address those conditions separately 2.
