RT Journal Article A1 Balaji, Seshadri A1 Rychik, Jack A1 Moore, Jeremy P. T1 Fontan Junctional Rhythm—Innocent Bystander or Silent Killer? JF JAMA Cardiology JO JAMA Cardiol YR 2024 DO 10.1001/jamacardio.2024.0689 SN 2380-6583 AB The Fontan operation for single-ventricle hearts alleviates cyanosis but creates a hemodynamically fragile circulation. Without a right ventricle, pulmonary flow is driven by venous pressure, making it the limiting factor for cardiac output. Furthermore, the obligatory rise in central venous pressure leads to hepatic and splanchnic congestion. Consequently, long-term consequences include Fontan failure (FF) and hepatic congestion resulting in Fontan-associated liver disease (FALD).
