The Horizon and History of Asia Pacific Heart Rhythm Society.

The Asia Pacific Heart Rhythm Society (APHRS) has grown very rapidly and efficiently after its founding in 2008. The success of our organization and rapid growth was due to the enthusiastic support by pioneer electrophysiologists and efforts by many physicians to cure heart rhythm disorders. With the experience of preceding arrhythmia symposia of inter-cities or international basis in the region, the organization could quickly grow to become APHRS. The mission of APHRS is to promote basic research and impro...

Reflections on the early invasive clinical cardiac electrophysiology era through fifty manuscripts: 1967-1992.

In 1967, researchers in The Netherlands and France independently reported a new technique, later called programmed electrical stimulation. The ability to reproducibly initiate and terminate arrhythmias heralded the beginning of invasive clinical cardiac electrophysiology as a medical discipline. Over the next fifty years, insights into the pathophysiologic basis of arrhythmias would transform the field into an interventional specialty with a tremendous armamentarium of procedures. In 2015, the variety and c...

Ablation of atrial fibrillation in patients with Brugada syndrome: A systematic review of the literature.

Supraventricular arrhythmias are common in Brugada syndrome (BS), and notoriously difficult to manage with medical therapy secondary to associated risks. Pulmonary vein isolation (PVI) is often utilized instead, but its outcomes in this population are not well-known. We aim to provide a holistic evaluation of interventional treatment for Atrial fibrillation (AF) in the BS population. Electronic databases Medline, Embase, Cinahl, Cochrane, and Scopus were systematically searched for publications between 01/0...

Implantable loop recorder in clinical practice.

The implantable loop recorder (ILR), also known as insertable cardiac monitor (ICM) is a subcutaneous device used for diagnosing heart rhythm disorders. These devices have been strongly improved and miniaturized during the last years showing several reliable features along with the availability of remote monitoring which improves the diagnostic timing and the follow-up strategy with a potential reduction of costs for health care. The recent advent of injectable ILRs makes the procedure even easier and more ...

The impact of catheter ablation for atrial fibrillation in heart failure.

Atrial fibrillation (AF) commonly co-exists with systolic heart failure (SHF) and its presence is associated with a worse prognosis. Despite this, a rhythm control approach using antiarrhythmic drugs (AADs) to reduce AF burden has demonstrated no prognostic benefit. Catheter ablation (AFA) is more effective than AADs at reducing AF burden. We performed a meta-analysis to evaluate the impact of AFA on outcomes in SHF. Electronic databases were systematically searched. We included only randomized controlled t...

Association of atrial fibrillation and gastroesophageal reflux disease: Natural and therapeutic linkage of the two common diseases.

Atrial fibrillation (AF) is a common arrhythmia and gastroesophageal reflux disease (GERD) is popular in Japan. The two common diseases share several predisposing factors such as lifestyle and senescence, and inflammation and oxidative stress play an important role in their development and progression. Incidental cases of AF treated successfully by proton pump inhibitor (PPI) applied for coexisting GERD have been sporadically reported. An increasing evidence indicates that GERD induces the initiation and th...

Utilization of cardiac resynchronization therapy in patients with heart failure in the Northern Region of New Zealand.

Cardiac resynchronization therapy (CRT) has been shown to improve morbidity and mortality for heart failure (HF) patients. Little is known about the trends in CRT use and outcomes of these patients in New Zealand.

Clinical outcomes of cardiac resynchronization therapy with and without a defibrillator in elderly patients with heart failure.

Evidence regarding the incremental benefit of cardiac resynchronization therapy (CRT) with a defibrillator (CRT-D) versus without (CRT-P) in elderly patients with heart failure is limited. We compared mortality and cardiac hospitalisation between CRT-D and CRT-P in the elderly.

True complete left bundle branch block reveals dyssynchrony evaluated by semiconductor single-photon emission computed tomography.

Conventional complete left bundle branch block (CLBBB) criteria sometimes result in a false-positive diagnosis that does not represent dyssynchrony. Recently, true CLBBB criteria have been proposed to detect responders to cardiac resynchronization therapy (CRT), although their correlation with severity of dyssynchrony or natural prognosis is unclear.

Coronary vein defibrillator coil placement in patients with high defibrillation thresholds.

Elevated defibrillation threshold (DFT) occurs in 2%-6% of patients undergoing implantable cardioverter defibrillator (ICD) implantation. Adding a defibrillation coil in the coronary sinus (CS) or its branches can result in substantial reductions in the mean DFT. However, data regarding acute success and long-term stability remain lacking. We report our experience with this bailout strategy.

SMART pass will prevent inappropriate operation of S-ICD.

Compared to screening ECG before implantation of a subcutaneous implantable cardioverter-defibrillator (S-ICD), selectable vectors without T-wave oversensing increase after S-ICD implantation. Newer algorithms have recently become available to reduce T-wave oversensing, such as SMART pass (SP). With this function, more selectable vectors are identified after S-ICD implantation. However, this improvement in eligibility utilizing SP has not yet been well validated. We aimed to clarify S-ICD eligibility before...

Novel method for the prediction of para-Hisian premature ventricular complexes from the electrocardiogram.

Catheter ablation of para-Hisian (PH) premature ventricular complexes (PVCs) has a high risk of heart block. This study aimed to find the electrocardiographic (ECG) predictors of PH-PVCs.

Updated results on catheter ablation of ventricular arrhythmias arising from the papillary muscles of the left ventricle.

Catheter ablation of ventricular arrhythmias (VAs) arising from the left ventricle`s (LV) papillary muscles (PM) is challenging. In this study we present results of catheter ablation using multiple energy sources and image-based approaches.

Midterm outcomes of catheter ablation for atrial fibrillation in patients with cardiac tamponade.

Cardiac tamponade is a serious complication of catheter ablation for atrial fibrillation (AF). However, the outcomes of catheter ablation in patients of cardiac tamponade are unknown.

Postmarketing surveillance on clinical use of edoxaban in patients with nonvalvular atrial fibrillation (ETNA-AF-Japan): Three-month interim analysis results.

Direct oral anticoagulants are the first-line drugs for anticoagulation therapy in nonvalvular atrial fibrillation (NVAF). However, a real-world, large-scale, clinical study on edoxaban has not been performed. Our ongoing postmarketing surveillance, ETNA-AF-Japan (doxaban reatment in routie clinical prctice in patients with non-valvular trial ibrillation; UMIN000017011), was designed to collect such data.

T wave oversensing in subcutaneous implantable cardioverter defibrillator secondary to hematoma formation: A potential cause of early postimplantation inappropriate shocks.

T wave oversensing (TWOS) is the most common cause of inappropriate shocks in subcutaneous cardioverter-defibrillators (S-ICD). We are presenting a patient with severe ischemic cardiomyopathy who received a S-ICD while on antiplatelets therapy. Pressure dressing was applied due to significant bleeding. On the first postoperative day, the device delivered 26 inappropriate shocks after removal of the pressure dressing. Interrogation revealed new TWOS, likely related to changes in the sensing vectors after hem...

Usefulness of lead repositioning from left to right sternal border for a patient with subcutaneous implantable cardioverter defibrillator showing high defibrillation threshold.

A 62-year-old man with Brugada syndrome underwent subcutaneous implantable cardioverter defibrillator implantation. The lead was positioned along the left sternal border and defibrillation threshold (DFT) testing was performed. However, ventricular fibrillation (VF) was not terminated with 65 J and 80 J shocks. Shock impedance was 82 ohms. We repositioned the lead to the right sternal border and performed DFT testing again, followed by the VF termination with a 65 J shock. Shock impedance was 59 ohms. ...

Simultaneous leadless pacemaker and subcutaneous implantable cardioverter-defibrillator implantation-When vascular options have run out.

An end-stage renal failure patient who was planned for a left brachioaxillary arteriovenous graft required an implantable cardioverter-defibrillator for secondary prevention of ventricular tachycardia and a pacemaker for complete heart block but was found to have a right subclavian venous occlusion. Due to the lack of vascular access, we performed a successful subcutaneous implantable cardioverter-defibrillator (S-ICD) and leadless pacemaker implantation. There was no interaction between the devices at the ...

One stage atrioventricular nodal ablation and leadless pacemaker implantation for refractory atrial fibrillation.

Atrioventricular nodal (AVN) ablation and right ventricular (RV) pacing is recommended for refractory atrial fibrillation (AF) and tachycardia-bradycardia syndrome. Three AF patients (mean age 83, range 79-89 years) underwent AVN ablation and transvenous leadless pacemaker Micra implantations using the same venous access without anticoagulation interruption. Satisfactory pacing 0.59 (0.50-0.63) V at 0.24 ms and sensing 11.2 (6.3-15.6) mV were achieved within 1-3 deployments. There were no vascular complic...

Unique abdominal twiddler syndrome.

Twiddler syndrome is an uncommon complication that occurs by twisting of the generator and may cause torsion, dislodgement, and injury of the leads. We report a rare case of a twiddler syndrome associated with an abdominal permanent pacemaker. Abdominal twiddler syndrome may possess a unique mechanism, which may not be seen in chest twiddler syndrome.

Dangerous noodle: A case of swallowing syncope and a review of 122 cases from the literature.

Swallowing syncope is a rare medical condition. Even though it has been known as a neurally mediated syncope, the definitive mechanism of this condition remains unclear. We show in this study an additional case of swallowing syncope and review the 122 reported cases from the literature. A 47-year-old Japanese man had been suffering from recurrent syncopal attacks, when he fainted immediately after swallowing. Holter electrocardiogram monitoring demonstrated a sinus pause (maximum R-R interval of 3.8 second...

Increasing pace mapping properties in parahissian premature ventricular contraction. Novel insight from HD grid multipolar catheter.

A 23-year-old athlete with symptomatic low burden premature ventricular contraction (PVC) with left bundle branch block morphology and inferior axis morphology was sent to our department for RV mapping and PVC ablation. Exit zone of the PVC was easily and clearly defined by the bipoles A3-A4 achieving optimal and detailed pacemapping (Panels A-C) near the His bundle (yellow dots). The spatial conformation and the smooth shape of the catheter would definitely help everyday procedures in the setting of low bu...

Pulmonary vein reconnection mapping with Advisor HD Grid demonstrating local EGM which were not visible on Tacticath ablation catheter.

We present a case of redo atrial fibrillation (AF) ablation for pulmonary vein reconnection. In mapping of posterior wall of left upper pulmonary vein (LUPV) with HD grid, a new and unique multipolar mapping catheter, it demonstrated presence of local electrocardiogram signals (EGM). But during mapping with the Tacticath ablation catheter, these signals were not visible. Nevertheless, ablation at this point resulted in isolation of LUPV. The unique mapping technology offered by HD grid mapping catheter may ...

Transient complete heart block following catheter ablation of a left lateral accessory pathway.

A 16-year-old female with symptomatic Wolff-Parkinson-White (WPW) syndrome underwent catheter ablation of a left-sided lateral accessory pathway. The accessory pathway was eliminated with the first ablation lesion; however, the patient immediately developed complete heart block (CHB). At first, complete heart block was thought to be due to ablation of left atrial extension of the AV node, and pacemaker therapy was considered. However, careful ECG analysis revealed that the development of CHB was in fact due...

Removal of a Hickman catheter using a laser sheath.

A 31-year-old female with 10 years indwelled Hickman catheter for idiopathic pulmonary hypertension presented infectious findings. We decided to remove it but simple traction did not work. Although it was an off labeled use, we could remove it using a laser sheath and snare technique without any complication.
