Roux-en-Y Gastric Bypass (RYGB) and Laparoscopic Sleeve Gastrectomy (LSG) induce significantly greater cardiac reverse remodelling (reduction in left ventricular mass and concentric remodelling) than Laparoscopic Adjustable Gastric Band (LAGB) in obese patients.

If you are considering bariatric surgery for obesity, the type of surgery matters for your heart health. Roux-en-Y Gastric Bypass (RYGB) and Sleeve Gastrectomy (LSG) are superior to Gastric Banding (LAGB) in reversing the structural changes in the heart caused by obesity. This benefit is driven by the greater reduction in visceral and epicardial fat, not just total weight loss. Discuss cardiac imaging and long-term heart health with your surgeon when choosing between these procedures.

GoodSupportsHIGH confidence
RYGB and LSG appear to result in greater decreases in visceral adiposity, and greater reverse LV remodelling with larger reductions in LVM, concentric remodelling and pericardial restraint than LAGB.

Why this rating

Multicentre study with CMR (gold standard for cardiac structure), but small sample size for LAGB (n=10) and non-randomized assignment of surgery type.
