Abstract:
Objective Ventricular resynchronization might be achieved via minimally invasive left ventricular epicardial lead placement Method Six patients with congestive heart failure underwent minimally invasive left ventricular epicardial lead placement after failed coronary sinus cannulation were followed up for 1 year, cardiac function and LV lead threshold were evaluated. Results There were no inhospital deaths, intraoperative complications and diaphragm stimulation. Correct lead positioning was achieved in all 6 patients. LV lead thresholds remained unchanged [(1.2±0. 5)Vvs(l.l±0. 4) V , P = 0. 68 ] at 12 months follow-up. Improvements on 6 min walking test [ ( 327 ± 77) m vs (267 ± 68) m, P = 0.001], LVEF[(26.1 ±6.0)% vs (38.2 ± 4.7)% ,P = 0.004], and NYHA functional class were evidenced at 12 months follow-up. Conclusion Minimally invasive left ventricular epicardial lead placement is a safe and reliable technique and should be considered as an alternative option in case of difficult coronary venous anatomy and inability to position the lead for resynchronization therapy.
