Abstract:
Objective To investigate the effect of operation mode,thickness,and number of implanted electrode leads on tricuspid regurgitation.Methods This was a single-center retrospective study.Patients who received their first cardiac implantable electronic device at the Second Affiliated Hospital of Harbin Medical University from January 2019 to January 2024 and were followed up within(10±4)months were continuously enrolled.General clinical data,preoperative and outpatient follow-up echocardiography,and other indicators were collected.According to the different operation modes,patients were divided into delivery sheath group,support wire group,and delivery sheath combined support wire group.Under the premise of only one electrode wire crossing the tricuspid valve,according to the different thicknesses of the electrode wire,they were divided into 3830 69 group(4.1 F),5076 58/Solia S60 group(7 F),and 6935M-65cm defibrillator group(9 F).The number of electrode wires was divided into 3830 69 subgroup and 6935M-65cm defibrillator subgroup under the premise of balanced operation mode and electrode material.The changes in tricuspid valve regurgitation were compared in each group.Results A total of 219 patients,aged(65.92±12.04)years,were enrolled.There was no difference in tricuspid valve regurgitation in the 6935M-65cm defibrillator subgroup before implantation(all P＞0.05).In the 3830 69 subgroup,there was a higher proportion of severe regurgitation in the two-electrode group before implantation(P=0.013).In comparison with the change in tricuspid valve regurgitation before electrode wire implantation and during follow-up,the regurgitation of the tricuspid valve in the 6935M-65cm defibrillator subgroup with≥2 electrodes was unexpectedly improved compared to that in the group with one electrode,and the regurgitation of the valve in the group with one electrode was more severe than that in the group with ≥ 2 electrodes implantation(P=0.019).Conclusions The operation mode and thickness of the implanted electrode lead did not cause significant differences in tricuspid valve regurgitation.Single implantation of a 6935M-65cm defibrillator electrode will lead to increased tricuspid regurgitation,and the effect brought by combination with physiological pacing will offset the adverse effects of electrode leads on the valve,providing directional evidence for future implantation strategy selection.
