Ventricular tachycardia and preload deficiency post LVAD - The importance of integrated assessment.

Ventricular tachycardia (VT) is common in LVAD recipients, and although often well tolerated, may result in symptoms and ICD therapies, and therefore require further evaluation and treatment. However, preload deficiency may also contribute to the development of ventricular tachycardia after LVAD implantation by provoking inflow cannula related VT. In this report, three cases are described where ventricular tachycardia was evaluated by integrated assessment utilizing echo and the HeartWare HVAD console, and successfully treated by modification of LV loading conditions.
