Abstract:

The pulmonary veins, responsible for carrying oxygenated blood from the lung to the left atrium for gaseous exchange, often exhibit variations. Understanding and mapping these variations is crucial for diagnosing atrial fibrillations and pulmonary arteriovenous malformations. This study, aimed at reporting the variations in the number of pulmonary veins and drainage patterns, presents findings from the dissection of a female cadaver in our Department of Anatomy. Notably, we observed variations in the drainage pattern of pulmonary veins on the left atrium. On the right side of the left atrium,

AbstractAnomalous drainage of the right superior caval vein into the left atrium is a rare congenital anomaly that causes cyanosis and occult infection owing to right-to-left shunting. Transcatheter management of this anomaly is unique and rarely reported.

Abstract:

Objective: Using a newly acquired archive of previously prepared material, we sought to re-examine the origin of the pulmonary vein in the human heart, aiming to determine whether it originates from the systemic venous sinus (“sinus venosus”), or appears as a new structure draining to the left atrium. In addition, we examined the temporal sequence of incorporation of the initially solitary pulmonary vein to the stage at which four venous orifices opened to the left atrium. Methods: We studied 26 normal human embryos, ranging from 3.8 mm to 112 mm crown-rump length, and representing the period

Abstract:

Total anomalous pulmonary venous drainage (TAPVD) is caused by the absence of the congenital connection between the pulmonary vein and left atrium. This causes blood drainage into the right atrium, resulting in poor development of the left atrium and increasing the burden for the right atrium. It is accompanied by an atrial septal defect. TAPVD mostly is diagnosed during the fetal period and rarely is reported in adults. Atrial fibrillation (AF), a common arrhythmia, originates primarily from the joint of the pulmonary vein and left atrium, whereas AF originating from the right atrium has not

Abstract:

The purpose of this study was to increase accuracy and success rate of radiofrequency catheter ablation by analysis of left atrial volume change relative to left ventricular volume change and left atrial diameter change relative to left atrial volume change. 20 patients with normal heart rhythm were set as the control group, and 20 patients with diagnosed atrial fibrillation were set as the experimental group. The cardiac cycle was divided into 10 stages ranging from 0% to 90%, and left ventricular volume, left atrial volume, left atrial diameter, pulmonary vein diameter were measured for each

Abstract:

The paper presents a clinical case of a 38-year-old woman who had an anomalous confluence of the right pulmonary vein, both into the inferior vena cava and into the left atrium, which corresponds to be the "scimitar" syndrome. The abnormal pulmonary vein made several bends before draining into the left atrium, which is described in foreign literature as a "meandering pulmonary vein". To clarify the diagnosis, a CT scan of the chest with bolus contrast enhancement and a deep analysis of literature sources were performed.

Abstract:

ABSTRACT Partial anomalous pulmonary venous return (PAPVR) is a rare congenital condition, and dual-drainage connection PAPVR to the left atrium has been reported in a few cases in the literature; in which cases, percutaneous catheterization was successfully used in lieu of surgery. We, hereby, describe a 7-month-old boy with a functional single-ventricle physiology with dual drainage of the left upper pulmonary vein to the left atrium and the innominate vein. Appropriate recognition of this entity allowed safe occlusion of the anomalous draining vein.

SummaryWe present a case of anomalous origin of the left pulmonary artery from a left-sided brachiocephalic artery via an arterial duct in a patient with a right aortic arch. Associated intracardiac anomalies were a large perimembranous ventricular septal defect and the persistence of a small vertical vein, connecting the pulmonary veins normally incorporated into the left atrium to the brachiocephalic vein. Spontaneous closure of the arterial duct occurred in the first days of life and was responsible for the circulatory “isolation” of the left pulmonary artery. The clinical course, surgical

Direct access to the left atrium via a thoracoscopic or pericardial approach with a balloon-tipped cryoablation catheter might facilitate endocardial cryoablation on the beating heart. We investigated the ability of a novel cryoballoon to produce endocardial pulmonary vein ostial cryolesions on the beating heart in a large-animal model. Methods Six sheep underwent small left thoracotomy. A 10.5F catheter with a 23-mm cryoballoon was inserted direct

Abstract:

Atrial fibrillation is the most common sustained cardiac arrhythmia and is associated with considerable morbidity and mortality. Electrically isolating the pulmonary veins from the left atrium by catheter ablation is superior to antiarrhythmic drug therapy for maintaining sinus rhythm, but its success varies depending on multiple factors, including arrhythmic burden. Although procedural outcomes have improved over the years, further gains are limited by a seemingly zero-sum relationship between effectiveness and safety, which is largely a product of the available technologies.

Abstract:

Total anomalous pulmonary venous connection refers to a spectrum of cardiac anomalies where the pulmonary veins fail to return to the left atrium and the pulmonary venous blood returns through a systemic vein or directly to the right atrium. There is a wide anatomical variety of venous connections and degrees of pulmonary venous obstruction that affect the presentation, surgical repair, and outcomes. In this review, we explore the preoperative physiology, echocardiographic diagnosis, and approach to postoperative complications.

Catheter ablation has become a cornerstone treatment for atrial fibrillation (AF). Pulmonary vein isolation is the accepted approach for paroxysmal AF ablation, but it is less effective for persistent AF. The vein of Marshall (VOM) is located in the epicardial left atrium and can be a source of AF triggers as well as a tract for autonomic nerves. It directly communicates with the underlying myocardium, including the left atrial ridge and the posterior mitral isthmus.

Two principal hypotheses account for intracardiac shunting in reptiles. The ‘pressure shunting’ hypothesis proposes that there is no fuctional separation between the ventricular cava during systole. The ‘washout shunting’ hypothesis suggests that the cavum pulmonale is functionally separated from the rest of the ventricle during systole. The purpose of this study was to test the two principal hypotheses in a turtle, Pseudemys scripta, after inducing a right-to-left shunt by electrical stimulation of the vagus nerve.
