Optimization of right ventricular lead position in cardiac resynchronization therapy
Original language description
Background The benefit of biventricular pacing (BiV) may be substantially affected by optimal lead placement. Aim To evaluate the importance of right ventricular (RV) lead positioning on clinical outcome of BiV. Methods and results A total of 99 patientswith symptomatic heart failure and implantation of BiV system were included. Position of the left-ventricular (LV) lead was selected based on timing of local endocardial signal within the terminal portion of the QRS complex. RV lead was preferably positioned at the midseptum (n = 74, RVS group) where the earliest RV endocardial signal was recorded. A subgroup of patients had RV lead placed in the apex (n = 25, RVA group). NYHA class, maximum oxygen-uptake (VO2max), LV end-diastolic diameter (LVEDD, mm)and ejection fraction were assessed every third month. A trend towards greater improvement in NYHA class and significant increase in VO2max was present in the RVS group. Moreover, a significant decrease in LVEDD (ΔLVEDD) was observe
