Abstract In this single center case series with nine percent primary diversion, 86 of 94 patients alive and with complete follow-up at one year had a functioning anastomosis. Seventy-five of the initial 99 patients never had a stoma. Meaning: Highly selective fecal diversion in combination with proactive leakage management, low anastomoses can be preserved safely, and the majority of patients will be spared all disadvantages of a diverting stoma. In this single-centre case series, with a primary diversion rate of 9 per cent, 86 of 94 patients who were alive and had complete follow-up at 1 year had a functioning anastomosis. Seventy-five of the initial 99 patients never had a stoma. The results indicate that, with highly selective faecal diversion in combination with proactive leakage management, low anastomoses can be preserved safely, and the majority of patients will be spared the disadvantages of a diverting stoma.

Background: Radiofrequency current ablation (RFA) of ventricular tachycardia (VT) focuses on endocardial (endo) substrates. However, if endo RFA fails, an epi approach is a potential treatment option. We report a single centre experience of epi VT ablation. Patients and Methods: Between 06/2005 and 02/2008 42 pts (14 female, mean age 49 ± 18 years) underwent electroanatomical endo and epi mapping and ablation for intractable VT, syncope or VT storm with multiple ICD discharges. Pts with normal heart (n=7), ischemic cardiomyopathy (ICM; n=8), NICM (n=11), ARVD (n=8), LV-aneurysm (n=7) or sarcoidosis (n=1) were studied. Mean LV ejection fraction was 45±12%. 20/42 had had at least 1 previous ablation attempt for VT (range 1– 4 ablations). Acute success was defined as non-inducibility of the previously inducible VT. Chronic success was defined as recurrence of any VT. Results: Acute procedural success rate was 79% (30/38). In 4 pts VTs were not inducible during EPS. In 28/42 pts endo mapping revealed no pathologic potentials. In 23/38 pts and 7/38 the succesful RFC ablation site was epi and endo, respectively. In 9/38 pts endo ablation failed and VT could only be ablated from epi. Further 7/38 pts needed both endo and epi ablation. In In 4/8 failed ablations epi RFC ablation was impossible due to failed access to target site (adhesions; n=2), close vicinity of a coronary artery (n=1) or the phrenic nerve (n=1). Procedure duration was 263±97 min. Unfortunately, 1 pt died due to perforation of RV and 1 pt had severe hepatic bleeding after epi puncture. One pt died in cardiogenic shock 1 d after the procedure. In 2 pts a sterile pericarditis occurred which resolved without any further intervention. After a median follow-up of 293 days (1–929 days) 53% of pts were alive and free from any VT. Conclusion: In pts with failed endo RFC ablation for VT due to different etiologies epi RFC ablation was acutely successful in 61% of pts with a moderate chronic success rate. However, major complications occured in approximately 5% of pts. Epi mapping should be considered if endo pathologic potentials are absent or if endo ablation failed.

The aim – to investigate the dynamic changes of the structural and functional state of the heart and the persistence of cardiac rhythm disorders in patients with acute myocarditis with preserved left ventricular ejection fraction (LV EF) during 6 months of follow-up. Materials and methods. 54 patients with acute myocarditis and preserved LV EF (> 40 %) of the left ventricle (LV) were screened. The examination was performed twice: in the first month from the debut of myocarditis and in 6 months of follow-up. Results and discussion. According to data obtained by CMR, in the 1st month from the disease onset, the early contrast on T1-weighted images and/or the high intensity of the signal on T2 images were detected in all patients, with their percentage being 66.6 % and 62.9 % respectively, and late enhancement was observed in 14.8 % of cases. After 6 months of observation, edema and myocardial hyperemia were detected only in 7.4 and 9.2 % of cases, and fibrotic changes were in 37.0 % of patients, while 59.2 % of patients had no pathological changes on CMR at all. The average number of affected by inflammatory changes LV segments in the 1st month was 2.33±0.23, and after 6 months it decreased to 1.43±0.17 segments (р<0.01). The value of LV EF increased from 47.3±2.3 % in the 1st month to 56.2±2.5 % after 6 months (р<0.05) of follow-up, and detection of non-sustained ventricular tachycardia (NSVT) episodes decreased from 20.4 % cases in the 1st month to 7.4 % of cases after 6 months. According to the results of the correlation analysis, a strong direct correlation was established between the number of LV segments involved in the inflammatory process in the 1st month from the myocarditis onset (r=0.81, р<0.01) as also after 6 months (r=0.72; р<0.01) and the presence of NSVT episodes, that was also confirmed by determining the exact Fisher criterion (p=0.019), statistically reliable correlations of the same direction were also established between the presence of NSVT episodes and fibrotic changes on cardiac MRI. Conclusions. For patients with acute myocarditis with a preserved LV EF, the absence of severe violations of the LV contractile function is characterized by a small amount of inflammatory lesions of myocardium. Clinically significant cardiac rhythm disorders, in particular episodes of non-sustained ventricular tachycardia, can be observed in these patients in the absence of significant violations of the structural and functional heart state and are associated with a greater number of LV segments affected by inflammatory and fibrotic changes.

Abstract Funding Acknowledgements Research grant from Abbott Introduction We have recently described a novel evaluation of AF voltage which correlates better with MRI-DE defined scar than sinus rhythm voltage. We evaluated the clinical efficacy of additional voltage-based substrate modification in the Persistent AF patient cohort in a single centre case series. Methods 22 PsAF patients undergoing catheter ablation were recruited. Left atrial electroanatomical maps were created in AF before any ablation was performed in all patients. Mean peak to peak AF voltage mapping was undertaken using 8s segments of AF (&lt;0.35mV).  PVI was then performed in all patients after which, further ablation lesions were delivered on the underlying scar tissue (transection, box formation or homogenisation). Results Of the 22 patients currently under follow up, 16 patients are more than 12 months after their initial procedure. 11/16 patients have had no recurrence and no patient is currently on anti-arrhythmic medication. Conclusion From our series, 69% of PsAF patients remain arrhythmia free at one year follow up post blanking period with a single procedure. Ablation of low voltage areas appears to infer incremental benefit in the Persistent AF population.
