In combination with surgery, CRT proved to be an effective therapy in those patients who were subsequently implanted. The suggested method is simple, without significant adjunctive risks, and allows easier CRT implantation with stable thresholds.

However, limited access to the septal regions with the use of this method has to be remembered. Transseptal approach may be considered as an alternative to the transaortic route in patients with contraindication to the latter.

Buprenorphine, a partial µ-opiate–receptor agonist and a κ-opiate–receptor antagonist does not cause QTP or TdP. Buprenorphine is a useful and effective alternative to methadone in a select group of patients, including those with documented ventricular arrhythmias on methadone. Pacemakers or defibrillators should be reserved for patients who have failed buprenorphine or a reduced methadone dose.

This is irrespective of the type of CIED, pacemaker dependancy or multiple 24-h scanning sessions. Our protocol addresses early detection of potential complications and establishes a response system for potential device-related complications. Our observation suggests that routine DFTT/DSMT post-MRI may not be necessary.

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.

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 the region and the location of the focus vary among the methods.

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 permanent pacemaker support.

Isthmus-dependent atrial flutter was diagnosed in a patient with complete situs inversus 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.

In patients with dilated cardiomyopathy (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 balloon. For successful implant of LV lead, with no viable alternatives available, the tortuosity of the lateral and posterolateral branch were overcome by advancing and infl...

We conclude that the fluctuations in the measured R wave are the result of waxing and waning inflammation associated with sarcoid activity. The patient had a stable medical course throughout the time period studied, including stable immunosuppression and stable electrolytes. We believe this is an example of an important complication of ICD implants in patients with cardiac sarcoidosis and that frequent sensing evaluations are prudent in these patients.

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 interventricular septum despite the demonstration of an LBBB-type VT.

The implanted system was upgraded to biventricular pacing. Resynchronization therapy was associated with normalized septal motion and shortening of the interventricular delay and, within 2 months after initiation, resulted in markedly improved left ventricular ejection fraction and reduced ventricular volume.

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.

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 with VF or VT storm. The Purkinje potential was seen just before the myocardial ventricular wave during sinus rhythm that became more prominent and double components duri...

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 the aorta (NCC) where the local atrio-ventricular electrogram amplitude ratio was >1 during both the AT and sinus rhythm. The tailored approach targeting the NCC AT ...

sinus rhythm through three distinct connections, either encompassing a single route or via any combination of these connections. In one third, the earliest LA activation occurs outside BB. The knowledge of the propagation patterns may give insight into the pathophysiology of PAF and into refining ablation therapy.

Alterations in structure and function of atrial ion channels associated with aging provide the substrate for AF. In this review we provide an overview of current knowledge regarding these age-related changes in atria, focusing on intrinsic ion channel function, impulse initiation and conduction. Studies on the action potentials (APs) of atria have shown that the AP contour is altered with age and the dispersion of AP parameters is increased with age. However, studies using human tissues are not completely consistent with experimental animal studies, since specimens from humans have been obtained from hearts with concomitant cardiovascular diseases and/or that are under the influence of pharmacologic age...

The available implantable devices at present need the use of permanent endocavitary leads which may cause, in some instances, serious troubles to the patients (lead dislodgement, ventricular perforation, lead infections, etc.). A new implantable defibrillator provided by only a subcutaneous lead is at present under evaluation. Its potential indications, usefulness benefits, and problems represent an interesting field of investigation and discussion. This paper describes the conclusions recently reached by a panel of experts, with regard to the potential role of an implantable subcutaneous defibrillator in the prevention of sudden cardiac death.

Long term follow-up and the control angio-CT revealed no further late vascular complications. Therefore, use of a collagen based closure device for treating accidental iatrogenic subclavian artery injury can be a simple, successful alternative therapy when surgical direct vascular repair is not possible or not available.

He complained of severe chest pain during the procedure. Subtle ST segment elevation was noted in the high lateral territory (I & aVL). He had no risk factors for coronary artery disease. The event occurred prior to any ablation within the left atrium (LA). He was haemodynamically stable (159/95 mmHg) and a pericardial effusion was excluded with transthoracic echocardiography. A coronary angiogram showed focal occlusion within a distal branch of the 1st diagonal. We discuss possible mechanisms for this unusual complication.

Small, discrete potentials resembling those of purkinje fiber were found at right ventricular apex, all these potentials showed early activation during tachycardia preceding the QRS onset of various degrees. Pace mapping helped to localize the presumed main distal insertion of the atrio-fascicular AP in a region where a damage of the His-purkinje system may ensue. This case report describes catheter ablation of an atriofascicular accessory pathway by targeting its distal (ventricular) insertion site.

Computed tomographic angiography revealed that coronary sinus ostium and part of the right atrial isthmus were located on the ventricular side of the valve ring due to the specific surgical approach in this condition. Based on the results of electroanatomic mapping and entrainment, the arrhythmia was found to be cavotricuspid isthmus dependent clockwise atrial flutter. Completion of the isthmus line required ablation lesions across the artificial valve. When these were delivered the arrhythmia terminated and isthmus block was achieved. Due to arrhythmia recurrence a redo procedure was performed which demonstrated conduction recovery in the ventricular part of the cavotr...

The results of this study reveal that protamine reactions present in a dramatic fashion often with profound hypotension. Although the incidence of protamine reactions in this setting is low (1.2%), they do occur. Electrophysiologists who use protamine need to be aware of this reaction and the appropriate therapeutic interventions.

Advanced age is also a potent risk factor for stroke in patients with AF, and the proportion of strokes attributable to AF increases exponentially with age. In addition, AF contributes incrementally to health care utilization and costs, and decrementally to survival and quality of life in older adults. Furthermore, the societal impact of AF will likely double over the next three decades due to the aging of the population. For these reasons, it is essential to develop more effective strategies for the prevention and treatment of AF in older individuals. Content Type Journal ArticleDOI 10.1007/s10840-008-...

She was free of cardiac medical history or medications. The resting ECG displayed an extended early repolarization in the inferior leads and all the precordial leads. Incessant ventricular fibrillations justified a treatment by intravenous amiodarone associated with general anaesthesia and mechanical ventilation without success on ventricular fibrillation. Because of a low heart rate intravenous isoproterenol infusion was initiated. Isoproterenol infusion was associated with heart rate acceleration and a decrease in J point elevation and the disappearance of ventricular fibrillation episodes.

After initial widening of the QRS complex, further widening was observed due to loss of His bundle capture. With the initial QRS widening, the stimulus-atrial interval and retrograde atrial activation sequence were almost unchanged, so the findings mimicked retrograde conduction over an accessory pathway. This may be a pitfall of the para-Hisian pacing technique.

In mammalian hearts, K+ channels are heterogeneously expressed across the ventricles resulting in ‘intrinsic’ DR that may worsen in long QT. DR was shown to be central to the arrhythmia phenotype of transgenic mice with LQT caused by loss of function of the dominant mouse K+ currents. Here, we investigated the arrhythmia phenotype of mice with targeted deletions of KCNE1 and KCNH2 genes which encode for minK/IsK and Merg1 (mouse homolog of human ERG) proteins resulting in loss of function of IKs and IKr, respectively. Both currents are important human K+ currents associated with LQT5 and LQT2. Loss of minK, a protein subuni...

Our results suggest that individual optimization and programming of V-V settings is necessary. The inability to predict optimal settings likely reflects the unique characteristics of each patient and supports the need for individualized programming of each device.

T-wave oversensing can often be resolved by certain programmable adjustments while accepting a small risk of undersensing ventricular fibrillation. The following case depicts a girl with LQT whose transvenous defibrillator repeatedly demonstrated T-wave oversensing despite optimizing various programmable features and a separate pace/sense lead. Utilization of an LV epicardial pace/sense lead with stable R-waves affirmed an unusual resolution of T-wave oversensing and avoidance of inappropriate shocks.

Reducing the risk of ischemic stroke is one of the cornerstones in the medical management of atrial fibrillation. Oral vitamin K antagonists such as warfarin are highly effective in preventing atrial fibrillation-related thromboembolism, but can be challenging to manage and are associated with increased bleeding risk. Aspirin therapy has modest efficacy in reducing stroke risk, but is much less effective than warfarin. To help guide the choice of optimal antithrombotic therapy, risk stratification for stroke in atrial fibrillation may be helpful, although most elderly patients derive a net benefit from w...

There is little research specifically focused on this topic in the elderly but five of the seven randomized controlled trials comparing pharmacologic rate control to pharmacologic rhythm control enrolled patients who can be considered “elderly”. Collectively, these studies showed that the rate control approach was favored for the outcomes of mortality, hospitalization and cost. With respect to stroke and systemic thromboembolism, no clear advantage accrues to either approach and the major therapeutic intervention for stroke prevention is anticoagulation. Rhythm control may be better for relief of symptoms in those who are highly symptomatic but symptoms are u...

At the time of the procedure, the patient presented moderate signs of heart failure and tachycardia-induced cardiomyopathy. During electroanatomical mapping we identified a focal atrial tachycardia with origin in the donor right atrium and bi-directional atrio-atrial conduction. After successful focal ablation the patient had two alternating atrial activation patterns, representing the recipient and the donor heart sinus rhythm. Two months after the ablation heart failure symptoms were in regress, and the patient was still in sinus rhythm. Content Type Journal ArticleCategory CASE REPORTDOI 10.1007/s1084...

Different transseptal approaches into the anterior chamber receiving the left atrial appendage and posterior chamber receiving the PVs, were achieved in two sessions. PVI of the left PVs and right superior PV was challenging via the anterior chamber, whereas PVI of the right inferior PV was challenging via the posterior chamber because of the disturbance of the membrane. Therefore, an intentional transseptal catheterization into the more appropriate chamber may be necessary for PVI in a cor triatriatum sinister.

Those two cases demonstrated that subsequent pregnancies might result in deterioration of VAs even though they exhibit no symptoms of heart failure. Those findings may clinically impact the decision making when women with a history of peripartum cardiomyopathy desire to become pregnant again. The VA foci in both cases were determined or suggested to be in the epicardium of the ventricular outflow tract from the results of the catheter ablation and electrophysiological study. Therefore, catheter ablation of those VAs may be feasible but challenging. Content Type Journal ArticleCategory CASE REPORTDOI 10.1007/s10840-008-9325-zAuthors Takumi Yamada...

Since atrial fibrillation is predominantly a disease of maturity, the majority of studies examining quality of life in this patient population have been conducted in older adults people (aged ≥65 years). Almost all studies have demonstrated poorer quality of life among patients with atrial fibrillation compared to age-matched general populations. Rate-control and rhythm-control strategies in highly symptomatic patients have revealed significant improvements in quality of life following the interventions, presumably as a result of the immediate relief of symptoms. Further, randomised controlled trials of rate- versus rhythm-control strategies have shown that some a...

Repeated cardioversions terminated the VT with immediate resumption after one sinus beat. Pacing neither terminated the VT nor demonstrated transient entrainment. Echocardiographically guided electroanatomic mapping revealed a centrifugal activation from the septal mid-apical region of the left ventricle on the septal portion of the posterior papillary muscle where a high frequency potential was observed within the local ventricular electrogram. Irrigated radiofrequency current at this site eliminated the VT. This case suggested that papillary muscles may be a target for catheter ablation of electrical storms after myocar...

To ensure safety, prior TEE may be necessary for the patients with planned catheter ablation for AF.

The purpose of our study was to determine the incidence and the predictive factors of post-ablation atrial fibrillation. One hundred and forty eight consecutive patients underwent cavotricuspid isthmus ablation for the treatment of typical atrial flutter between January 2004 and December 2005 in our electrophysiological department. Complete cavotricuspid isthmus block was successfully obtained in 96.6% of the patients. At the end of the electrophysiological study a sustained atrial fibrillation was inducible in 20 patients (13.5%). During an average follow-up of 21.3 ± 8.2 m...
