AB  - BACKGROUND: Competent lateral and posterolateral valves showed proximal 
      tortuosity that might hinder left ventricular (LV) lead implantation in cardiac 
      resynchronization therapy (CRT). CASE SUMMARY: A 57-year-old woman was diagnosed 
      as non-ischaemic cardiomyopathy, no other comorbidities, complaining of dyspnoea 
      [New York Heart Association (NYHA) class III], and on optimal medical therapy. 
      Electrocardiogram showed left bundle branch block with QRS duration 150 ms. The 
      patient was candidate for CRT. However, during LV lead implantation, a competent 
      posterolateral vein valve and proximal tortuosity hindered LV lead implantation 
      that was overcome by balloon-assisted tracking technique. At 9 months of 
      follow-up, the patient had NYHA class II, ejection fraction improved to 38%, and 
      all implanted leads were still in place. DISCUSSION: Balloon-assisted tracking 
      technique can be used to cross coronary sinus and smaller veins with competent 
      valves and coronary veins tortuosity.
