ABSTRACT
Objective:
To evaluate incidence of postoperative ventricular arrhythmias in patients who received cardiac resynchronization therapy defibrillator (CRT-D ) with left ventricular quadripolar lead.Methods:
The patients received CRT-D who had complete follow-up data in Anhui Provincial Hospital from June 2013 to June 2016 were included and divided into quadripolar lead group and bipolar lead group according to the type of left ventricular lead. And ventricular arrhythmia (VA), implantable cardioverter-defibrillator (ICD) shocks treatment, antitachycardia pacing therapy (ATP), and other indicators of the two groups were compared. Prognosis of the two groups was assessed by re-hospitalization for heart failure and cardiac death.Results:
Of the 220 patients enrolled in the study, 58 patients were in quadripolar lead group and 162 in bipolar lead group, and there were no significant differences in baseline characteristics between the two groups. The VA episode per patient was not significantly different between the two groups [(0.60±2.38) VA per person vs (0.93±2.24) VA per person, P=0.055]; the quadripolar lead group had significantly lower burden of VA compared with bipolar lead group [(0.22±0.91) per person-year vs (0.46±1.13) per person-year, P=0.044]. Compared with bipolar lead group, there were significant reduction in both the ICD shocks per patient and the burden of ICD shocks in quadripolar lead group [(0.12±0.36) shocks per person vs (0.23±0.52) shocks per person, P=0.034] and [(0.04±0.17) per person-year vs (0.12±0.46) per person-year, P=0.029], respectively. There were no significant differences between the two groups in both the ATP per patient and the burden of ATP [(1.07±3.77) ATP per person vs (1.26±3.01) ATP per person, P=0.073] and [(0.38±1.39) per person-year vs (0.63±1.48) per person-year, P=0.058], respectively. And there were no significant differences between the two groups for the survival (P=0.496).Conclusion:
Compared with bipolar lead group, the burden of VA could be significantly reduced after CRT-D in the quadripolar lead group.Palavras-chave
