INTRODUCTION Segmental ostial ablation to isolate pulmonary veins is guided by pulmonary vein potentials. The aim of this prospective randomized study was to compare the utility of unipolar plus bipolar electrograms versus only bipolar electrograms as a guide for segmental ablation to isolate the pulmonary veins in patients with atrial fibrillation. METHODS AND RESULTS Isolation of the left s...
Pulmonary vein stenosis is a fascinating yet frustrating and difficult to manage condition with an exceptionally high mortality rate. Until recently, the disease was seen almost exclusively in young children with or without various forms of congenital heart disease. Pulmonary vein stenosis is a relatively rare condition. In most published series from large centers, there has been an average of ...
a2-year-old cachectic cross-breed gelding was admitted toveterinary teaching hospital of university of tehran followingthe onset of a marked respiratory distress, coughing and ventraledema. clinical examinations indicated harsh respiratory andexpiratory sounds as well as jugular vein distention. therespiratory and heart rates were 35/min and 60 bpm, respectively.agrade iii/iv pansystolic murmur...
Introduction Atrial fibrillation ablation is an increasingly frequent procedure performed in the electrophysiology laboratory. Pulmonary vein foci account for more than 90% of triggers for atrial fibrillation, most commonly treated with complete pulmonary vein isolation most of the time. Non–pulmonary vein triggers are the drivers of atrial fibrillation in a subgroup of patients. This patient h...
We describe a rare case of cyanosis following the Fontan operation with right-to-left shunting at the venous level, that is, an azygos venous to pulmonary venous connection. Few cases with partial anomalous pulmonary venous connection to azygos vein have been reported; however, there have been no reports describing the connection from azygos vein to pulmonary vein, which results in desaturation...
Scimitar vein is the partial anomalous pulmonary venous connection usually draining lower pulmonary lobe to the inferior vena cava or right atrium. We present a scimitar vein anomaly in a 34-year-old woman with the uncommon association of a secundum type of atrial septal defect and atretic right upper pulmonary vein. She presented with increasing dyspnea for 2 months, however, she was asymptoma...
Anomalous Pulmonary venous connection is drainage of one or more pulmonary veins outside left atrium. Venous Connection most common on Left side upper vein drains directly into innominate to ultimately drain right Right Partial can be Superior Vena Cava, Atrium, Innominate rarely Inferior Cava.
abstract horseshoe lung is a congenital pulmonary malformation that is usually associated with scimitar syndrome. this malformation consists of fusion of both pulmonary lobes from the posterobasal segments. the fusion appears in the retrocardiac area, in front of the esophagus and thoracic aorta. pleural separation of pulmonary lobes distinguishes pseudohorseshoe appearance from a true horsesho...
