Most tachycardias in the pulmonary venous atrium are inaccessible by direct means and require either a retrograde approach or a transseptal approach for ablation. We present a case in which successful radiofrequency ablation of common atrioventricular nodal reentrant tachycardia was accomplished via a retrograde transaortic approach guided by nonfluoroscopic mapping with use of the NavX(™) mapping system. The patient was a 49-year-old woman who at the age of 4 years had undergone Mustard repair for complete dextrotransposition of the great arteries...

Adults who underwent complex atrial baffling as children via Mustard or Senning procedures are at heightened risk for atrial arrhythmias. Antiarrhythmic therapies are typically ineffective in this population. Accordingly, our team of pediatric and adult electrophysiologists investigated the effectiveness of early invasive transbaffle-access techniques to perform early radiofrequency ablation at the source of these clinically significant arrhythmias. For this retrospective study, we selected 11 adult survivors of atrial baffling (mean age, 34 ± 9 yr) who underwent clinically indicated electrophysiologic study after no more than one trial of antiarrhythmic therapy...

Pathologic perforating veins have become an interest to the venous specialist caring for patients with CEAP 4 to 6 disease. Historically, open perforator ligation and then subdermal endoscopic perforator ligation was described. These methods had clear shortcomings. More recently, thermal ablation techniques, including radiofrequency ablation and laser ablation, have been described. Ultrasound-guided sclerotherapy has also been used as a possible means to treat pathologic perforator veins. This report describes and summarizes the updated techniques to treat perforating veins in a challenging patient population...

OBJECTIVE: Endovenous heat-induced thrombosis (EHIT) is a well-documented phenomenon that follows endovenous ablation, but the treatment, surveillance, and risk factors for EHIT have yet to be comprehensively elucidated. We sought to identify characteristics that may put patients at higher risk for development of EHIT after radiofrequency ablation (RFA) for the treatment of symptomatic superficial venous insufficiency. METHODS: A retrospective review was performed of all consecutive patients undergoing treatment with RFA to the great saphenous vein by a single surgeon from July 2013 through October 2015...

Left ventricular diastolic dysfunction in hypertrophic cardiomyopathy (HC) increases susceptibility to atrial fibrillation. Although phenotypical characteristics of the hypertrophied left ventricle are clear, left atrial (LA) and pulmonary venous (PV) remodeling has rarely been investigated. This study aimed to identify differences in LA and PV remodeling between HC and hypertensive heart disease (HHD) using 3-dimensional computed tomography. Included were 33 consecutive patients with HC, 25 with HHD, and 29 without any co-morbidities who were referred for catheter ablation of atrial fibrillation...

Idiopathic epicardial ventricular tachycardias (VTs) account for 9% of idiopathic VTs. The recognition of this entity is important, as a minimally invasive ablation procedure performed exclusively through the coronary sinus branches may be considered, avoiding the potential risks associated with access to the left ventricular endocardium, the aortic root, and the pericardial space. The electrocardiographic features and therapeutic management of this rare form of tachycardia are discussed.

INTRODUCTION: Today, reconstructive surgeons offer an array of options to reconstruct the lip defects. Herein we present our experience of using free double-paddle peroneal flaps for extensive lip defect reconstruction. PATIENTS AND METHODS: From 1996 to 2014, 16 patients with extensive lip defects after tumor ablation were included. Free double-paddle peroneal flaps were used for reconstructions. In terms of flap design, one skin paddle superiorly placed on the lateral lower leg was used to reconstruct intraoral defects, whereas the other was inferiorly located and was used to reconstruct extraoral defects...

BACKGROUND: Catheter ablations have been traditionally performed with the use of fluoroscopic guidance, which exposes the patient and staff to the inherent risks of radiation. We have developed techniques to eliminate the use of fluoroscopy during cardiac ablations and have been performing completely fluoroless catheter ablations on our patients for over 5 years. METHODS: We present a retrospective analysis of the safety, efficacy, and feasibility data from 500 consecutive patients who underwent nonfluoroscopic catheter ablation, targeting a total of 639 arrhythmias, including atrioventricular reciprocating tachycardia (AVRT), atrioventricular nodal reentrant tachycardia (AVNRT), atrial tachycardia (AT), atrial fibrillation (AF), premature ventricular contractions (PVC), and ventricular tachycardia (VT)...

Incompetent superficial veins are the most common cause of lower extremity superficial venous reflux and varicose veins; however, incompetent or insufficient perforator veins are the most common cause of recurrent varicose veins after treatment, often unrecognized. Perforator vein insufficiency can result in pain, skin changes, and skin ulcers, and often merit intervention. Minimally invasive treatments have replaced traditional surgical treatments for incompetent perforator veins. Current minimally invasive treatment options include ultrasound guided sclerotherapy (USGS) and endovascular thermal ablation (EVTA) with either laser or radiofrequency energy sources...
