Are malignant ventricular arrhythmias well tolerated in patients receiving long-term left ventricular assist devices?
Absence of right ventricular contraction during malignant ventricular arrhythmias is well tolerated in recipients of a left ventricular assist device. The diagnosis of malignant arrhythmia should be suspected if an unexplained decrease in left ventricular assist device flow occurs. Early electrical cardioversion is warranted to avoid both thrombus formation in the native heart and right ventricular myocardial injury from prolonged fibrillation.
The prophylactic use of G-CSF during induction of ALL is associated with improved long-term outcome and should be recommended especially in a setting of T-ALL and in 'young adults'. Our analysis provides the first direct evidence coming from prospective trials for the impact of primary G-CSF prophylaxis on disease-free survival of oncological patients.
