Of these, 35,396 patients had at least one episode of warfarin treatment interruption. In all, 8255 deaths or thromboembolic events occurred during treatment interruption showing an initial clustering of events during 0–90 days. The first 90-day interval of treatment interruption was associated with a markedly higher risk of death or thrombo-embolism (incidence rate ratio-IRR 2.5) vs the interval of 271–360 days. The authors concluded that in this patient population with AF, almost 3 out of 4 patients on warfarin treatment had one or more periods of treatment interruption. Interruption of warfarin therapy was associated with a significantly increased short-term risk of thrombo-embolism or death during the first 90 days of interruption (Raunso J et al, Eur Heart J 2012; 33: 1886–1892).Left Ventricular Dyssynchrony May Determine Outcome Following CRT in Patients with RBBB and Help in the Selection of CRT Candidates Echocardiography was performed in 561 cardiac resynchronization therapy (CRT) recipients (89 with RBBB & 472 with LBBB) before and 6 months after CRT. RBBB patients had a higher prevalence of male gender, ischemic heart disease, atrial fibrillation, and lower exercise capacity when compared with LBBB patients, despite smaller left ventricular (LV) volumes. In addition, the extent of both interventricular and LV dyssynchrony was less in RBBB patients. At 6 months, RBBB patients also showed limited LV reverse remodelling. LV dyssynchrony and mitral regurgitation were identified as independent predictors of all-cause mortality or heart failure hospitalization among RBBB patients. The authors concluded that RBBB patients referred for CRT exhibit interventricular and LV dyssynchrony, albeit less than their LBBB counterparts; preimplantation LV dyssynchrony may be an important determinant of death or heart failure hospitalization among CRT recipients with RBBB (Leong DP et al, Eur Heart J 2012; 33: 1934–1941)...
