Complete drainage of the pulmonary veins into the right heart is one of the rarest and most severe congenital cardiac anomalies. The X-ray studies may suggest this diagnosis if pulmonary veins enter either coronary sinus or inferior vena cava. In the case reported, right heart catheterization and angiocardiography were used and the diagnosis of persisent left superior vena cava and partial dire...

the radiologic features of intralobar pulmonary sequestration (ilps) have been describe and include the identification of a feeding systemic artery with venous drainage through pulmonary veins. primary sequestration associated with typical hamartoma signs is really rare and has been described only once. we describe a patient with ilps whose radiographic findings were unusual for two reasons. fi...

BACKGROUND Radiofrequency ablation of tissues in pulmonary veins can eliminate paroxysmal atrial fibrillation. OBJECTIVE To explore the characteristics of normal pulmonary veins so as to provide more information relevant to radiofrequency ablation. METHODS 20 structurally normal heart specimens were examined grossly. Histological sections were made from 65 pulmonary veins. RESULTS The lon...

CONGENITAL STENOSIS of individual pulmonary veins as they join the left atrium is a rare cause of pulmonary venous and arterial hypertension. Cases have been reported by Reye,1 Ferencz and Dammann,2 Andrews,3 Bernstein and associates,4 and Edwards.5' 6 Emslie-Smith and associates7 reported a patient with membranous occlusion of the pulmonary veins associated with pulmonary hypertension. The pur...

Rev Esp Cardiol 2002;55(6):671-2 671 Congenital atresia of the pulmonary veins is a rare anomaly that is not associated with other heart disease. It has a poor prognosis and patients die secondary to pulmonary hypertension, recurrent hemoptysis, pulmonary edema, or congestive cardiac insufficiency. We present a 5-year-old male patient admitted to the hospital for asthenia, anorexia, hemoptoic v...

In this paper we intend to confine ourselves to the strictly surgical aspects of anomalies of the pulmonary veins in a series of 25 patients who were operated on in this clinic. Anomalies of the pulmonary veins are very often associated with communications between the systemic and the pulmonary circulation, such as atrial septal defect, patent ductus arteriosus, or ventricular septal defect. An...

We describe a simple and safe technique to position a bipolar radio-frequency ablation device around the pulmonary veins when performing pulmonary vein isolation. The technique consists of insertion of a rubber catheter with stylet, originally an introducer from a left vent catheter, behind the pulmonary veins, and subsequent placement of the lower jaw of the ablation clamp using a rubber cathe...

INTRODUCTION Recent studies demonstrated that atrial arrhythmias may be generated within pulmonary veins. The purpose of this study was to compare the endocardial activation times at effective and ineffective ablation sites during radiofrequency catheter ablation of arrhythmias initiated or generated within pulmonary veins. METHODS AND RESULTS Twenty-one of 28 patients without structural hear...

All of our cases of abnormal pulmonary venous connections collected to the middle of 1965 and verified at surgery or autopsy have been reviewed by means of diagrams and tabulations, using a specially devised code to facilitate the survey. The material consisted of 52 autopsy cases (half of them obtained after surgery) and the cases of 72 patients who survived operation. The postmortem group was...

Radiofrequency catheter ablation of pulmonary veins has emerged as an effective therapy for patients with symptomatic atrial fibrillation. Advances in real-time intracardiac echocardiography with 2D and Doppler color flow imaging have led to it integration in atrial fibrillation ablation procedures. It allows imaging of the left atrium and pulmonary veins, including identification of anatomic v...
