In the 30 patients, 26 (86.7%) patients had a predominantly indirect hyperbilirubinemia, suggesting a likely presence of PFA\u2010induced hemolysis. The liver enzyme contents post ablation were normal in all patients and no signs of hemolytic anemia and renal function injury were detected. The impact factors associated with indrect hyperbilirubinemia were also analyzed and higher number of applications tented to produce PFA\u2010induced hemolysis. More than 86.5 applications seem to have a better sensivity and specificity to predict hemolysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Intravascular hemolysis can occur after utilizing novel hexaspline catheter, but the severity of hemolysis was mild and temporary.
