Diagnosis of myocardial infarction with nonobstructive coronary arteries in a young man in the setting of acute myocardial infarction after endoscopic retrograde cholangiopancreatography: A case report.

Background: Acute myocardial infarction (AMI) is characterized by chest pain as well as cardiac troponin I (cTnI) and electrocardiography (ECG) changes. Recently, clinical researchers have used the term "MINOCA" to indicate myocardial infarction with nonobstructive coronary arteries. To the best of our knowledge, no report has documented MINOCA in a young patient after choledocholithiasis by endoscopic retrograde cholangiopancreatography (ERCP).

Very long-term outcome of catheter ablation of post-incisional atrial tachycardia: Role of incisional and non-incisional scar.

Background: The arrhythmogenicity of right atrial (RA) incisional scar after cardiac surgery could result in atrial tachycardia (AT). Radiofrequency catheter ablation is effective in the treatment of such tachycardia. However, data regarding long-term outcomes are limited.

The characteristics of verapamil-sensitive idiopathic left ventricular tachycardia combined with a left accessory pathway and the effect of radiofrequency catheter ablation.

Aims: Verapamil-sensitive idiopathic left ventricular tachycardia (ILVT) combined with a left accessory pathway (AP) is a relatively rare condition. This study examines the characteristics of patients with this condition and the effect of radiofrequency catheter ablation (RFCA).

Methods And Results: Catheter ablation was performed on 140 ILVT patients at a single centre from January 2004 to December 2009.

Focal atrial tachycardia originating from the distal portion of the left atrial appendage: characteristics and long-term outcomes of radiofrequency ablation.

Aims: The characteristics and response to ablation therapy of focal atrial tachycardia (AT) originating from the distal portion of left atrial appendage (LAAd) are still not quite clear up to now. The goal of this study is to characterize electrocardiographic and electrophysiological features and radiofrequency ablation (RFA) outcomes in patients with focal AT originating from the LAAd.

Methods And Results: Fourteen patients (2.

Is selective ipsilateral PV isolation sufficient for focally triggered paroxysmal atrial fibrillation? Comparison of selective ipsilateral pulmonary vein isolation versus bilateral pulmonary vein isolation.

Introduction: Selective ipsilateral pulmonary vein isolation (SIPVI) has shown comparable efficacy in focal triggered atrial fibrillation (AF) versus isolation of all pulmonary veins (PVs), yet the sufficiency for such an ablation strategy to all patients is unclear. This study sought to identify a subgroup of patients for SIPVI and a subgroup of patients for bilateral PV isolation (BiPVI) with long-term success by comparing the clinical efficacy of SIPVI and BiPVI on PV-triggered AF.

Methods And Results: One hundred and forty-two patients (106 males; mean age 51 ± 13 years) with focal PV triggered paroxysmal AF (PAF) were studied.

Single dose of ibutilide for conversion of persistent atrial fibrillation after radiofrequency ablation.

Background: Patients with persistent or permanent atrial fibrillation (AF) often need direct current cardioversion after radiofrequency ablation. The aim of this study was to investigate the effectiveness and safety of ibutilide for cardioversion of persistent or permanent atrial fibrillation after radiofrequency ablation and the factors related to conversion.

Methods: Patients with persistent or permanent atrial fibrillation were treated with combined ablation strategy including circumferential pulmonary vein isolation, linear ablation and CAFÉ potential ablation.
