Iatrogenic atrial septal defect after HotBalloon ablation of atrial fibrillation.

HotBalloon-based pulmonary vein isolation (HBPVI) has yielded encouraging clinical results in the treatment of atrial fibrillation (AF). Balloon ablation requires a larger sheath, which raises the concern for a persistent iatrogenic atrial septal defect (iASD). The present study aimed to investigate the incidence, clinical features, and the predictive factors of transthoracic echocardiography (TTE)-detectable iASD after HBPVI.

Pulmonary vein stenosis after HotBalloon pulmonary vein isolation of paroxysmal atrial fibrillation.

HotBalloon-based pulmonary vein isolation (HBPVI) has yielded encouraging clinical results in the treatment of paroxysmal atrial fibrillation (PAF). However, pulmonary vein (PV) stenosis remains a concern. The influence of longer application duration on PV stenosis has not yet been systematically evaluated.

Acute efficacy and clinical outcomes using HotBalloon for pulmonary vein isolation in patients with a left common pulmonary vein.

Introduction: HotBalloon material is compliant and the balloon size can be enlarged by increasing the intraballoon injection volume. HotBalloon-based pulmonary vein isolation (PVI) has demonstrated encouraging clinical results in the treatment of paroxysmal atrial fibrillation (PAF), however, the acute efficacy and clinical outcomes of the HotBalloon-based PVI have never been fully investigated in patients with a left common pulmonary vein (LCPV).

Methods And Results: One hundred fifty-three PAF patients underwent HotBalloon-based PVI.

Insights into guidewire related complication during HotBalloon ablation in patients with atrial fibrillation: What should we know?

A 78-year-old woman with drug-resistant persistent atrial fibrillation was referred for catheter ablation by HotBalloon. All pulmonary veins were successfully ablated by the HotBalloon. During the additional roof ablation by the HotBalloon, sudden hemoptysis developed.

The feasibility of a Box isolation strategy for non-paroxysmal atrial fibrillation in elderly patients.

Background: Catheter ablation of non-paroxysmal atrial fibrillation (non-PAF) is a therapeutic challenge especially in elderly patients. This study describes the feasibility of a posterior left atrium isolation as a substrate modification in addition to pulmonary vein isolation, the so-called Box isolation, for elderly patients with non-PAF.

Methods: Two hundred twenty-nine consecutive patients who underwent Box isolations for drug-refractory non-PAF were divided into two groups according to their age; younger group comprising 175 patients aged <75 years and elderly group comprising 54 patients aged ≥75 years.

Is It Necessary to Achieve a Complete Box Isolation in the Case of Frequent Esophageal Temperature Rises? Feasibility of Shifting to a Partial Box Isolation Strategy for Patients With Non-Paroxysmal Atrial Fibrillation.

Introduction: There are some cases with frequent luminal esophageal temperature (LET) rises despite titrating the radiofrequency energy while creating a linear lesion for the Box isolation of atrial fibrillation (AF). Little is known about the feasibility of redesigning the ablation lines for a modified Box isolation strategy to prevent fatal esophageal injury in those cases.

Methods And Results: Two hundred and seventeen patients who underwent a Box isolation of non-paroxysmal AF were evaluated.

Long-Term Results of Radiofrequency Hot Balloon Ablation in Patients With Paroxysmal Atrial Fibrillation: Safety and Rhythm Outcomes.

Introduction: Isolation of pulmonary veins (PVs) and the posterior left atrium (LA) can be safely performed by radiofrequency hot balloon (RHB)-based box isolation. However, data on long-term effects for the treatment of atrial fibrillation (AF) by the use of this method remain limited.

Methods And Results: We treated 238 patients with paroxysmal AF (194 male; age.

A case of repeated occlusion in the common iliac artery due to an unexpected stent deformation.

We report a case experiencing repeated common iliac artery (CIA) occlusion due to an unexpected stent deformation. A 74-year-old man with intermittent claudication had undergone balloon-expandable stenting for the left CIA. Six years after his first stent implantation, his left CIA was totally occluded inside the stent.

Efficacy of metal tip catheter for chronic total occlusion lesions in peripheral arterial disease.

We performed several techniques for chronic total occlusion (CTO) lesions in peripheral arterial disease (PAD). We evaluated the cases using the metal tip catheter (MT). We performed peripheral endovascular therapy (EVT) using MT in 31 cases 32 lesions of PAD from March 2007 to March 2011.

A case of limited cutaneous systemic sclerosis developing anti-mitochondria antibody positive primary biliary cirrhosis after acute myocardial infarction.

In this report, we present a 63-year-old woman who had limited cutaneous systemic sclerosis and subsequently developed typical primary biliary cirrhosis after an acute myocardial infarction. The patient initially developed Raynaud's phenomenon, and 4 years later visited the clinic in 1994 complaining of abdominal distress, xerostomia, and xerophthalmia. A diagnosis of limited cutaneous systemic sclerosis was based on Raynaud's phenomenon, sclerodactyly and anti-centromere antibodies.
