Long-Term Safety and Procedural Performance of an Interatrial Shunt for Heart Failure According to Ejection Fraction.
BACKGROUND Long-term device durability and phenotype-specific safety outcomes after interatrial shunting require further characterization. OBJECTIVES This study aimed to evaluate the procedural success, device durability, and heart failure (HF) phenotype-specific safety outcomes of an interatrial shunt in the RELIEVE...
