“…So far, most studies have focused on a single type of AF (e.g., paroxysmal/persistent or permanent AF) and were often conducted in the setting of a clinical trial (15)(16)(17)(18)(19). The prevalence and prognostic implications of a history of AF at ICD implantation remain unclear.…”

“…19,21,22 This death rate is consistent with the severity of heart disease in our population, which had a median LV ejection fraction of 0.25, a history of heart failure in 62%, and atrial fibrillation in 29%, all markers of increased risk of death from heart failure. [21][22][23][24][25] In addition, spontaneous ventricular arrhythmias are associated with increased rates of death and heart failure even in patients with ICDs, suggesting that they are a marker for deteriorating ventricular function. 2 It is interesting that of the 24 patients who died within 6 months, 19 (79%) had failed ablation and had recurrent episodes of VT.…”

Background-Recurrent ventricular tachycardia (VT) is an important cause of mortality and morbidity late after myocardial infarction. With frequent use of implantable cardioverter-defibrillators, these VTs are often poorly defined and not tolerated for mapping, factors previously viewed as relative contraindications to ablation. This observational multicenter study assessed the outcome of VT ablation with a saline-irrigated catheter combined with an electroanatomic mapping system. Methods and Results-Two hundred thirty-one patients (median LV ejection fraction, 0.25; heart failure in 62%) with recurrent episodes of monomorphic VT (median, 11 in the preceding 6 months) caused by prior myocardial infarction were enrolled. All inducible monomorphic VTs with a rate approximating or slower than any spontaneous VTs were targeted for ablation guided by electroanatomic mapping during sinus rhythm and/or VT. Patients were not excluded for multiple VTs (median, 3 per patient) or unmappable VT (present in 69% of patients). Ablation abolished all inducible VTs in 49% of patients. The primary end point of freedom from recurrent incessant VT or intermittent VT after 6 months of follow-up was achieved for 123 patients (53%). In 142 patients with implantable cardioverter-defibrillators before and after ablation for intermittent VT who survived 6 months, VT episodes were reduced from a median of 11.5 to 0 (PϽ0.0001). The 1-year mortality rate was 18%, with 72.5% of deaths attributed to ventricular arrhythmias or heart failure. The procedure mortality rate was 3%, with no strokes. Conclusions-Catheter ablation is a reasonable option to reduce episodes of recurrent VT in patients with prior myocardial infarction, even when multiple and/or unmappable VTs are present. This population remains at high risk for death, warranting surveillance and further study. (Circulation. 2008;118:2773-2782.)

“…AF is the most common arrhythmia in patients and is a major cause of congestive heart failure [5]. For instance, AF is present in 10-15% of patients with congestive heart failure and is highly prevalent in functional class IV patients [6,7]. AF also causes stroke and is a predictor of mortality [4].…”

Evaluation of a new epicardial cryoablation system for the treatment of Cardiac Tachyarrhythmias

Background: With the recent reports of success, there is now increasing use of cryoablation as a standalone, minimally invasive procedure to treat various cardiac arrhythmias. With increased use, a need for new devices and treatment strategies to deliver improved outcomes has emerged. In this study we investigated the performance of a new super critical nitrogen (SCN) epicardial cryoprobe for the targeted ablation of cardiac tissue. We hypothesized that the SCN technology would enable the rapid, effective delivery of ultra-cold temperatures thereby enabling more effective ablation.
