“…Similarly, there was no interference of the HeartMate II pump on the magnetic field with the ability to accurately track the MediGuide catheter tip (Figure 3), nor with the quality of electrograms observed on the ablation catheter. This finding is consistent with previous reports that have suggested no significant electromagnetic interference between the HeartMate II device and radiofrequency delivery; electroanatomic mapping with the CARTO system, which generates a magnetic field of 2.5–65 µT at frequencies of 2, 2.2, and 3 kHz (Biosense Webster; Johnson & Johnson, New Brunswick, NJ), or EnSite NAVx system (frequency 5.7 kHz; St. Jude Medical) 7, 8, 9, 10…”

“…8 Catheter ablation offers an opportunity to reduce or eliminate these events and has been shown to be feasible in single center studies. [9][10][11] However, the electrophysiological characteristics and outcomes associated with catheter ablation for VAs in patients with Heart Mate II (HM2) device (Thoratec) have not yet been evaluated in a multicenter series.…”

Background-Left ventricular assist devices (LVADs) are increasingly used as a bridge to cardiac transplantation or as destination therapy. Patients with LVADs are at high risk for ventricular arrhythmias. This study describes ventricular arrhythmia characteristics and ablation in patients implanted with a Heart Mate II device. Methods and Results-All patients with a Heart Mate II device who underwent ventricular arrhythmia catheter ablation at 9 tertiary centers were included. Thirty-four patients (30 male, age 58±10 years) underwent 39 ablation procedures. The underlying cardiomyopathy pathogenesis was ischemic in 21 and nonischemic in 13 patients with a mean left ventricular ejection fraction of 17%±5% before LVAD implantation. One hundred and ten ventricular tachycardias (VTs; cycle lengths, 230-740 ms, arrhythmic storm n=28) and 2 ventricular fibrillation triggers were targeted (25 transseptal, 14 retrograde aortic approaches). Nine patients required VT ablation <1 month after LVAD implantation because of intractable VT. Only 10/110 (9%) of the targeted VTs were related to the Heart Mate II cannula. During follow-up, 7 patients were transplanted and 10 died. Of the remaining 17 patients, 13 were arrhythmia-free at 25±15 months. In 1 patient with VT recurrence, change of turbine speed from 9400 to 9000 rpm extinguished VT. Conclusions-Catheter ablation of VT among LVAD recipients is feasible and reasonably safe even soon after LVAD implantation. Intrinsic myocardial scar, rather than the apical cannula, seems to be the dominant substrate.

“…Conversely, the incidence of heart failure hospitalization has reportedly increased due to AF, suggesting that the right side of the heart remains sensitive to the hemodynamic effects of AF. A small case series demonstrated an improvement in right heart failure after catheter ablation of AF in patients with LVADs [8]; therefore, rhythm control may be an important strategy for managing right heart failure for this group of patients. If it was difficult to control of our patient's right heart failure, we considered the catheter ablation of AF.…”

Background: Continuous-flow left ventricular assist devices (LVADs) improve survival and morbidity in patients with stage D heart failure. Management of LVADs for longer durations is necessary in some clinical settings, and a better understanding of the hemodynamics of patients using LVADs is warranted. Arrhythmia, including atrial (AA) and ventricular (VAs) arrhythmias, is a modifying factor of hemodynamics that is highly prevalent among patients with LVADs. However, the clinical impact of arrhythmias in various clinical settings in patients with LVAD, in which the hemodynamic load is likely to present as worsening of right heart failure, remains to be completely elucidated. Case presentation: We describe the case of a patient under sustained ventricular fibrillation for extraordinarily long duration who was stabilized using LVAD support and in whom newly developed atrial fibrillation led to a significant worsening of right heart failure while using an LVAD. Conclusion: This case demonstrates the substantial clinical impact of AAs in the management of right heart failure using an LVAD.
