BACKGROUND Pulmonary vein (PV) isolation is an established treatment strategy for paroxysmal atrial fibrillation (PAF). However, the recurrence rate of PAF is 8% to 37%, despite repeated procedures, and the catheter ablation strategy for PAF with non-PV foci is unclear. OBJECTIVE The purpose of this study was to assess the PAF ablation strategy for non-PV(More)
BACKGROUND Data regarding long-term mortality and factors influencing appropriate therapies in Japanese patients with implantable cardioverter defibrillators (ICD), who satisfy the Multicenter Automatic Defibrillator Implantation Trial II (MADIT II) criteria for primary prevention, remain scarce. METHODS A total of 118 consecutive patients who underwent(More)
BACKGROUND Catheter ablation can reduce episodes of ventricular tachycardia (VT) after myocardial infarction (MI). However, the optimal endpoint of the ablation procedure remains unclear. METHODS Fifty-one consecutive patients who received catheter ablation for VT after MI were included. The procedures targeted the isthmus of all the induced, sustained(More)
A case illustrating the value of aggressive respiratory training in improving the prognosis of lung cancer complicated by low pulmonary function is reported. Preoperative and postoperative respiratory training enabled the patient with chronic respiratory failure to survive a lengthy operation and eventually breathe without assistance. The patient has(More)
BACKGROUND The causative organism in cardiovascular implantable electronic device (CIED) infection is usually diagnosed with the cultures from blood, removed leads, and/or infected pocket material. The cultured organism, however, is sometimes different among these samples. METHODS Two hundred sixty patients with CIED infection, who underwent lead(More)
Idiopathic left ventricular aneurysms and diverticula (LVA/Ds) are rare cardiac malformations that can be detected using certain imaging techniques. Although most patients with these malformations are clinically asymptomatic, some patients exhibit cardiac arrhythmias and other clinical manifestations. In electrophysiological studies, it is often difficult(More)
BACKGROUND Lead extraction using laser sheaths is performed mainly for cardiac implantable electronic device (CIED) infections. However, there are few reports concerning the management of CIED infections in Japan. METHODS AND RESULTS Lead extraction procedures were performed in 183 patients targeting 450 leads (atrial leads: 170, ventricular: 181,(More)
BACKGROUND The clinical efficacy of catheter ablation (CA) for paroxysmal atrial fibrillation (PAF) in patients with sick sinus syndrome (SSS) and the mechanism and predictors of recurrence are not yet completely elucidated. METHODSANDRESULTS Of 963 consecutive patients who underwent PAF ablation during the study period, a total of 108 patients with SSS(More)
