Ablation of premature ventricular complexes (PVCs) originating from left ventricular outflow tract (LVOT)/left ventricular summit (LVS) is challenging with considerable rate of failure. Recently, in a novel approach to ablation of these arrythmias, application of radiofrequency energy to anatomically opposite sites of presumed origin of arrythmia, has been associated with moderate procedure success. Although late elimination of PVCs that are persistent following an ablation procedure has been previously reported, this observation has not been studied sufficiently. In this report, firstly, we present three cases of lately eliminated LVS PVCs, then, we discuss possible mechanism of this observation and conclude that after an initial failed attempt of anatomic ablation, operators may choose a period of watchful waiting before attempting a redo procedure.

The Anatolian Journal of Cardiology is an international monthly periodical on cardiology published on independent, unbiased, double-blinded and peerreview principles. The journal's publication language is English however titles of articles, abstracts and Keywords are also published in Turkish on the journal's web site.The Anatolian Journal of Cardiology aims to publish qualified and original clinical, experimental and basic research on cardiology at the international level. The journal's scope also covers editorial comments, reviews of innovations in medical education and practice, case reports, original images, scientific letters, educational articles, letters to the editor, articles on publication ethics, diagnostic puzzles, and issues in social cardiology.The target readership includes academic members, specialists, residents, and general practitioners working in the fields of adult cardiology, pediatric cardiology, cardiovascular surgery and internal medicine.

Interventional cardiologists encounter a wide range of lesions that cannot be angiographically distinguished from fixed atherosclerotic obstructive disease. In this case report, we document vasospasm at multiple sites in the coronary territory in a patient presenting with acute coronary syndrome. A 61-year-old woman was referred to our hospital with typical chest pain lasting approximately 1 h. After performing the left coronary artery angiography, a severe tubular stenosis was detected in circumflex (Cx) artery. Diffuse spasm was observed in the right coronary artery (RCA) and it resolved after intracoronary administration of nitroglycerin. After performing left system angiography again, severe stenosis in Cx artery was also completely resolved. Our finding is of clinical importance in that it is more likely to simulate a constant coronary stenosis than would have spasm occurred proximally. The clinical importance of our report is that a catheter-induced vasospasm (CIV) may simulate fixed coronary stenosis, not always osteally and in some instances at multiple sites. Awareness of this phenomenon and liberal use of nitroglycerin in any patient with discrete luminal narrowing, even when an ostial "lesion" is not present, can help to avoid misinterpreting CIV as an atherosclerotic lesion.

The purpose of this study is to investigate incidence of gastrointestinal symptoms and complications in patients who underwent high-power short-duration (HPSD), posterior left atrial wall isolation during atrial fibrillation ablation and thereafter have received gastrointestinal prophylactic regimen consisting of sucralfate, proton-pump inhibitor and colchicine. Patients were followed and assessed at baseline, up until 6th month following the procedures.Among 115 patients who were included, 5 patients (4.3%) reported gastrointestinal symptoms at follow-up. No complications were diagnosed during the follow-up. In conclusion, the HPSD along with prophylactic regimen has been associated with low incidence of gastrointestinal adverse events.
