Wed, 08 Feb 2012 09:32:45 +0100 Long‐Term Efficacy of Single Procedure Remote Magnetic Catheter Navigation for Ablation of Ischemic Ventricular Tachycardia: http://www.medworm.com/index.php?rid=5666903&cid=s_29168_7_f&fid=29168&url=http%3A%2F%2Fdx.doi.org%2F10.1111%252Fj.1540-8167.2011.02243.x Conclusion: RMN guided RF ablation of ischemic sustained VT is equally efficient compared with manual ablation in terms of acute and long‐term success rate. These results are achieved with a significantly reduced fluoroscopy time and shorter RF time.

Patients with depression should not be excluded from CRT, because they demonstrate a similar rate of response than the persons without depression and the responders are less likely to be depressed at 6 months.

Cautious management is required during AF ablation, especially in the patients with low LVEF.

These data support that the ICD shock itself has no worse impact on the outcome of ICD patients.

These changes provide important insights into the isolated effects of PH fundamental to a range of clinical conditions associated with AF.

The left posterior fascicle may be a bystander of the circuit of verapamil‐sensitive idiopathic left ventricular tachycardia. During ventricular tachycardia (VT), 3 sequences of potentials were seen at the left posterior septum: diastolic Purkinje potentials propagating from base to apex and presystolic left posterior fascicular potentials and systolic left ventricular (LV) myocardial potentials propagating in the reverse direction. Selective capture of the left posterior fascicle by the sinus beat did not affect the VT cycle length. Entrainment pacing revealed that the retrograde limb of the circuit was not the left posterior fascicle, but the LV myocardium.

Preoperative cardiac computerized tomography revealed a fistulous connection between the aortic root and the right atrium. Later, the patient underwent successful surgical closure of the fistula during the Cox Maze procedure. In this paper, we also discuss the clinical presentation, natural history, anatomy of the interatrial septum, and management of aorto‐cameral fistula.

It does not improve overall procedural success rate and procedural duration. Tissue cooling by CS blood flow is just one of the several challenges in MI ablation.

Optimal PV occlusion and few controlled repositionings facilitate PVI.

This supports current guideline recommendations for no antithrombotic therapy in these “truly low‐risk” patients.

Both atrioventricular (AV) and interventricular (VV) timing intervals have been suggested as potential methods to improve response rates. A variety of techniques have been described to determine the optimal AV and VV delays. Many of these methods have demonstrated acute hemodynamic benefits; however, multicenter data proving long‐term clinical benefit have been lacking. Echocardiography‐guided methods have been most commonly employed, but no technique has been shown to be superior. In fact, many of these techniques have poor reproducibility and are time‐consuming.

Men are more susceptible than women to low‐dose methadone‐associated QTc prolongation.

These changes may in part be responsible for the increased propensity to AF associated with systemic HT.

Methicillin‐resistance is common in this population. Currently, we would recommend vancomycin as first‐line empirical therapy. However, given that not all patients tolerate vancomycin, we believe that newer antimicrobial therapies should now be tested in clinical trials to establish their clinical effectiveness in treating patients with device infections.

Intraprocedural gaps are more likely to become bigger over time and persist, while new gaps also occur during follow‐up. Further studies are warranted to verify whether the presence and persistence of a peridevice gap is associated with increased risk of thromboembolic event in AF patients implanted with a WATCHMAN device.

Diagnosis was based on features of the HV interval assessed from a bipolar recording during mapping. The location of the arrhythmic focus was identified using simultaneous unipolar and bipolar recordings of the His electrogram. This case report highlights the use of 2 new criteria for the diagnosis and mapping of Hisian ectopy, and the successful use of cryothermia for the ablation of extrasystoles arising from the His bundle.

In 3 of the 4 patients AF was controlled after ablation without antiarrhythmic drug therapy and in the fourth patient AF was controlled with antiarrhythmic therapy after ASD  closure.

The most feared complication associated with atrial fibrillation (AF) is stroke, the risk of which increases with advanced age. Because of its complex anatomy and diminished blood flow during AF, the left atrial appendage (LAA) has been a common site of left atrial thrombi and presumed source of thromboembolism. Systemic anticoagulation to treat what may be largely a localized phenomenon is associated with significant complications. Newer anticoagulation agents hold great promise in facilitating dosing and eliminating drug and food interactions, but do not eliminate bleeding risk. These challenges have led to interest in mechanical exclusion of the LAA as a means of preventing thromboembolism in AF. Although surgery permits greater visualization and management of complications, the poten...

Late CVEs after RFA are more prevalent in older than younger patients with AF, and age >75 years old is the only independent predictor of late CVEs regardless of the rhythm, anticoagulation status, or the CHADS2 score (Congestive heart failure, Hypertension, Age ≥ 75 years, Diabetes mellitus and prior Stroke or transient ischemic attack).

A quarter of patients diagnosed needed more than 18 months of follow‐up. As consequence, when a strategy of prolonging monitoring is chosen, monitoring should be maintained even for several years until diagnosis is established.

These changes may in part be responsible for the increased propensity to AF associated with systemic HT.

Absence of LGE does not rule out the presence of small scars, and EAM with biopsy should be considered to increase the diagnostic yield.

AF termination retrospectively occurred on overlapping CFE/DF sites where DF was above the mean. However, prospective ablation of DF sites plus PVAI resulted in low AF termination rates, and did not improve 1 year success over PVAI alone.

Especially, the goal of keeping the patient in deep sedation while maintaining spontaneous ventilation and cardiovascular hemodynamic stability was accomplished. Endotracheal intubation or consultation of an anesthesiologist was not necessary in any patient.

CFAE ablation after PVAI was associated with a significantly higher elimination of those non‐PV triggers. This suggests that at least part of the beneficial effect achieved by CFAE ablation reflects elimination of non‐PV AF triggers.

Antithrombotic therapy using vitamin K antagonists (VKA) is currently prescribed for prevention of ischemic stroke in patients with AF. A narrow therapeutic range and frequent food and drug interactions underly the need for regular monitoring of anticoagulation intensity and impairs the utility and safety of VKA, stimulating a quest for alternative anticoagulant agents. Recently developed anticoagulants include the direct thrombin inhibitor, dabigatran, and the factor Xa inhibitors rivaroxaban, apixaban, edoxaban, to name those in the most advanced stages of clinical development. This review focuses on advances in the development of ...

Integration of the individual patient's surgical anatomy with the arrhythmia pattern on 12‐lead electrocardiogram can help both to narrow the potential arrhythmia diagnoses and to facilitate therapeutic decision making. This case highlights the differential diagnosis and management of such a patient. (J Cardiovasc Electrophysiol, Vol. pp. 1‐3) (Source: Journal of Cardiovascular Electrophysiology) Journal of Cardiovascular Electrophysiology journals http://www.medworm.com/rss/comments.php?id=4923147 Thu, 09 Jun 2011 23:00:00 +0100 4923147
