Response to Letter Regarding Article, “Ablation of Persistent Atrial Fibrillation Targeting Low-Voltage Areas With Selective Activation Characteristics” We thank Bartoletti et al for their comments on our novel approach for ablation of persistent atrial fibrillation (AF) targeting selective atrial low-voltage sites. Here we provide answers to their(More)
INTRODUCTION Irrigated tip radiofrequency (RF) catheter ablation is the most frequently used technology for pulmonary vein isolation (PVI). The purpose of this study was to compare the efficiency and the safety of 2 different open irrigated tip RF ablation catheters. METHODS AND RESULTS A total of 160 patients with symptomatic AF (29% persistent, 68%(More)
INTRODUCTION Pulmonary vein reconnection (PVR) is an important cause of AF recurrence after ablation. With the advent of force sensing catheters, catheter-tissue contact can be determined quantitatively. Since contact force (CF) plays a major role in determining the characteristics of RF lesion, we prospectively assessed the mechanisms of PVR with regard to(More)
Back-up support during percutaneous coronary interventions (PCI) is one of the keys for successful intervention. Extra back-up support guiding catheters, deep intubation, buddy wires, and other more complex techniques are usually used to improve this support. Left anterior descending (LAD) artery PCI through the left internal mammary artery (LIMA) are(More)
The subaxial spine has high risk of fatal damage by trauma and thereby requires more accurate and aggressive treatment. For the proper treatment and predicting the prognosis, the evaluation to reveal the risk factors for the prognosis is important. We analyzed the various factors contributing to the prognosis in distractive extension injuries of the(More)
Implantable cardioverter defibrillation has taken a predominant place in secondary and primary preventions of sudden rhythmic cardiac death in high-risk patients. However, in certain clinical situations, the implantation of definitive system should be postponed. The LifeVest, a portable external cardiac defibrillator system, has emerged as a novel(More)
A 72-year-old female renal transplant recipient was admitted with asthenia and low-grade fever. Two months earlier, she developed nodular pulmonary infiltrates (Figure 1), and microbiological examination of bronchoalveolar lavage fluid established the diagnosis of pulmonary nocardiosis. She had been taking ciprofloxacin and minocycline since that time.(More)
INTRODUCTION The circular irrigated decapolar nMARQ ablation catheter designed for treating atrial fibrillation (AF) has recently been recalled following two deaths due to esoatrial fistula. Injury to the esophagus has been previously reported in up to 50% of patients using 20-25 W unipolar radiofrequency (RF) energy. Low power of 15 W has been proposed to(More)
OBJECTIVE The objectives of the present study were to assess the efficacy and tolerability of perioperative paclitaxel/platinum-based chemotherapy and surgery in patients with stage IIIA clinical N2 (cN2) non-small cell lung cancer (NSCLC). METHODS Clinical N2 was defined as either >15 mm or >10 mm and multiple nodes on computed tomography (CT) scan.(More)
