Pulmonary vein antrum isolation by radiofrequency ablation has become a preferred treatment for atrial fibrillation. The aim of our research is to study the anatomy of the PVantrum and its related structures with special emphasis on the esophageal relation to the various components of the antrum, as thermal injury is a common complication.

Most hemodialysis patients start renal replacement therapy with a central venous catheter (CVC). The left internal jugular vein (LIJV) is the second-choice vein for CVC positioning, after the right IJ...
A knowledge of pulmonary vein anatomy variants allows an appropriate preoperative radiological assessment and safe surgical management of vascular anomalies in patients undergoing major lung resection...
Congenital right pulmonary artery to left atrium fistula is rare cause of cyanosis. It is an abnormal fistulous connection between right pulmonary artery and left atrium representing a direct communic...
The significance of inducibility of atrial fibrillation (AF) after pulmonary vein isolation (PVI) in patients with AF remains disputable and polarizing. Therefore, we investigated the prognostic value...
A pulmonary artery sling is formed when the left pulmonary artery originates from the right pulmonary artery and encircles the distal trachea, coursing between the trachea and esophagus to reach the h...
This is a prospective, single center, safety and feasibility trial to evaluate the transplantation of the left atrium and pulmonary veins in patients with pulmonary vein stenosis. Consente...
As the left atrium is in close vicinity to the esophagus, radiofrequency ablation in the left atrium may damage the esophagus and create esophageal perforations and esophageal left atrial ...
The aim of the study is to evaluate the accuracy and reproducibility of the left atrium (LA) anatomy and function in different populations and in patients with atrial fibrillation who have...
This study is a prospective, multicenter, randomized controlled study to evaluate the safety and effectiveness of the LARIAT System to percutaneously isolate and ligate the Left Atrial App...
Atrial fibrillation (AF) is a common heart rhythm disorder which can significantly affect a patient's quality of life. Abnormal electrical activity from the 4 veins that drain into the le...
A malformation of the heart in which the embryonic common PULMONARY VEIN was not incorporated into the LEFT ATRIUM leaving behind a perforated fibromuscular membrane bisecting the left atrium, a three-atrium heart. The opening between the two left atrium sections determines the degree of obstruction to pulmonary venous return, pulmonary venous and pulmonary arterial hypertension.
Placement of a balloon-tipped catheter into the pulmonary artery through the antecubital, subclavian, and sometimes the femoral vein. It is used to measure pulmonary artery pressure and pulmonary artery wedge pressure which reflects left atrial pressure and left ventricular end-diastolic pressure. The catheter is threaded into the right atrium, the balloon is inflated and the catheter follows the blood flow through the tricuspid valve into the right ventricle and out into the pulmonary artery.
An anomalous pulmonary venous return in which the right PULMONARY VEIN is not connected to the LEFT ATRIUM but to the INFERIOR VENA CAVA. Scimitar syndrome is named for the crescent- or Turkish sword-like shadow in the chest radiography and is often associated with hypoplasia of the right lung and right pulmonary artery, and dextroposition of the heart.
A short vein that collects about two thirds of the venous blood from the MYOCARDIUM and drains into the RIGHT ATRIUM. Coronary sinus, normally located between the LEFT ATRIUM and LEFT VENTRICLE on the posterior surface of the heart, can serve as an anatomical reference for cardiac procedures.
Diversion of the flow of blood from the pulmonary veins directly to the aorta, avoiding the left atrium and the left ventricle (Dorland, 27th ed). This is a temporary procedure usually performed to assist other surgical procedures.
Barrett’s esophagus is a condition in which the tissue lining the esophagus—the muscular tube that carries food and liquids from the mouth to the stomach—is replaced by tissue that is similar to the intestinal lining. This process is ca...
