Anatomical analysis of recurrent conduction after circumferential ablationEmail this article to a colleague.
Save this article to My Clippings.
Discuss or comment on this article.
Conclusions In the left antrum, there was a correlation between electrophysiologic (RoC) and anatomic (long segment) properties. The observation
in both antra that RoC often occurred in previously unablated areas suggested that, as an alternative to recovery of ablated
myocardium, a second mechanism of RoC was plausible: conduction via unablated myocardium, which was not immediately manifest.
These observations have compelled us to modify our circumferential lesion.

Activation mapping of focal atrial tachycardia: the impact of the method for estimating activation timeEmail this article to a colleague.
Save this article to My Clippings.
Discuss or comment on this article.
Conclusion The three methods of activation time determination, although highly correlated with one another, may generate foci of different
sizes and in different locations. However, the foci tend to cluster within relatively large areas of low-amplitude fractionated
electrograms. These findings suggest a sizeable atrial region with particular electrophysiological proprieties and raise the
possibility of an anatomical substrate of the tachycardia. During mapping, this region can be roughly delineated by all three
methods of activation time estimation. However, details concerning the activation pattern within ...

Conclusion In WPW syndrome patients, RF catheter ablation of AP results in an ‘immediate’ decrease in atrial vulnerability. Since inducibility
of AF becomes more difficult in this less vulnerable atrium, the AP itself may play an important role in the development of
AF.

Conclusion Compared to the other two procedures, patients with PVAI had the best survival rates at the end of 7 years. However, the observational
case-control design of this study incurs the potential for confounding due to non-randomized treatment selection, and creates
a major limitation in making valid generalization of the findings.

Conclusions One of the likely explanations may be that in the chain of events in HDC-KO mice on the one hand and in Streptozotocin-induced

This link may be a similar shift in the expression/function of certain K+ channel populations.

Conclusions: In swine with preserved ventricular conduction, in vivo pacing of the RVOT and LVA was associated with preserved, physiologically similar electrical activation sequences and LV
function relative to RAA pacing. In contrast, RVA pacing caused widespread electrical dyssynchrony of the LV and prolonged
activation durations, thereby impairing associated cardiac performance. Such insights into alternate site cardiac pacing,
which employed the combination of high-resolution electrical mapping with real-time hemodynamic assessments, may further increase
acute and long-term benefits in patients requiring...

and interruption of the inferior vena cava with azygos continuation. Under these unusual circumstances, Cartosound facilitates
interventional navigation within the right atrium and its adjacent structures and minimizes radiation exposure.

Conclusions Symptoms in PAF are predicted by changes in AF episode duration, ventricular rate during AF, preceding sinus heart rate, AV

Abstract Implantation of specifically designed left ventricular (LV) lead is a relatively complex procedure that depends on the anatomy

(DCM) tortuosity of the selected branch of coronary sinus (CS) leads to difficult or failed LV placement. A case study of
a 45-year-old woman with DCM requiring lead placement is presented here. To plan for proper LV lead positioning, CS angiography
was obtained through right femoral vein approach with preshaped long sheath (SJM, SL3) and occlusive balloo...

Abstract In this case report, we describe markedly fluctuating ventricular sensing through an implantable cardioverter defibrillator

an example of an important complication of ICD implants in patients with cardiac sarcoidosis and that frequent...

Abstract This case report describes a left bundle branch block (LBBB)-type ventricular tachycardia (VT) with a unique reentrant circuit
in a patient with cardiac sarcoidosis. The VT morphology and pace mapping supported an exit site of the VT from the basal
posterior right ventricle (RV) septum. Nonetheless, concealed entrainment was established by pacing from a septal left ventricular
(LV) site recording a diastolic potential, opposite site to the RV site. A point ablation at that LV site could successfully
terminate the VT, suggesting that a critical isthmus was located on the LV side of the interventricul...

of the interventricular delay and, within 2 months after initiation, resulted in markedly improved left ventricular ejection

Abstract Mechanical pressure applied to a Brockenbrough needle at the fossa ovalis is the standard transseptal puncture technique.
Circumstances where the fossa ovalis is thick or aneurysmal can make this method challenging. In this case, we illustrate
the use of a radiofrequency powered transseptal needle to cross the fossa ovalis.

Conclusions Lower systolic strain of LA was strongly associated with recurrence after catheter ablation. Thus, diverse adjunctive ablation
strategies should be considered to reduce recurrence in patients with lower systolic strain.

Conclusions Cryo of AFL can successfully be performed using the same application duration as used for RF ablation. Both acute and long-term
results are comparable to RF ablation. AFL recurrences occurred in only a minority of patients with resumption of CTI conduction.

Applications of computed tomography and magnetic resonance imaging in percutaneous ablation therapy for atrial fibrillationEmail this article to a colleague.

Discuss or comment on this article.
Abstract Percutaneous catheter ablation is an established therapy for symptomatic drug-refractory atrial fibrillation (AF). Accurate
delineation of relevant anatomy is critical but often challenging and limited in traditional technologies such as intra-procedural
fluoroscopy. There has been an increased interest in non-invasive three-dimensional imaging technologies, especially computed
tomography (CT) and magnetic resonance imaging (MRI), as useful tools for patients undergoing AF ablation. Here, we review
applications of CT and MRI before, during, and after AF ablation and highlight areas for future resear...

Conclusion Longer AF duration, older age and larger LA size are associated with fine AF amplitude. High F-wave amplitude predicts procedural
termination of arrhyhmia in patients with persistent AF and freedom from AF upon follow-up.

Discuss or comment on this article.
Conclusion SAH-induced cardiac changes can be attributed to adenosine triphosphate depletion through mitochondrial dysfunction. Pretreatment
of NAC to SAH on the other hand had a positive effect on these cardiac changes. But the exact mechanism by which NAC treatment
protects the cardiac muscle needs further investigation.

Conclusions Rotational angiography by RVP is able to delineate the LA-PV anatomy. There is a good correlation in the PV ostial diameters
as assessed by rotational angiography via RVP and CT imaging. Rotational angiography by RVP is feasible during AF ablation.

Catheter ablation of fatal ventricular tachyarrhythmias storm in acute coronary syndrome—role of Purkinje fiber networkEmail this article to a colleague.
Save this article to My Clippings.
Discuss or comment on this article.
Abstract Ventricular fibrillation (VF) or ventricular tachycardia (VT) storm is a life-threatening arrhythmia. Antiarrhythmic drugs
(AADs) are not necessarily effective to rescue life from such conditions. Catheter ablation (CA) targeting triggering premature
ventricular contractions (PVCs) of VF or VT that originates from Purkinje fiber network (PFN) is reported to be effective,
especially in idiopathic patients. However, in condition of acute coronary syndrome (ACS), the efficacy of CA is not well
understood. To clarify the usefulness of CA as an alternative way to AADs, we performed CA in four patients wi...

Abstract A 60-year-old woman was referred for catheter ablation of atrial fibrillation (AF). Atrial flutter and atrial tachycardia
(AT) also had been clinically documented. During the electrophysiological study, the clinical AT was induced by burst atrial
pacing during isoproterenol infusion and exhibited negative P waves in the inferior leads, positive P waves in leads I, aVL,
and aVR, and biphasic P waves in lead V1. The AT repeatedly and spontaneously accelerated to initiate AF by causing fibrillatory
conduction in the atria. Successful catheter ablation of the AT was achieved in the non-coronary cusp of ...
