The purpose of this study is to compare the efficacy and safety of PV isolation with continued antiarrhythmic drug treatment (PVI+ADT) to PV isolation without continued ADT (PVI-ADT) in pa...
The purpose of this study is to determine whether catheter-based pulmonary vein isolation is superior to antiarrhythmic drugs as first line therapy in patients with symptomatic paroxysmal ...
Background: Circumferential pulmonary vein ablation (CPVA) has been safely and effectively performed for treating paroxysmal atrial fibrillation (PAF); however, its safety and efficacy, as...
The investigators prospectively investigate the differences between contact-force guided pulmonary vein isolation (PVI) and conventional pulmonary vein isolation in patients with paroxysma...
We conduct a randomized study comparing the safety and effectiveness of two interventional ablation techniques for treatment of paroxysmal atrial fibrillation: the segmental pulmonary vei...
Pulmonary vein isolation (PVI) is generally performed under analgosedation, but sedation protocols vary and no optimal protocol has been defined. We investigated procedural, respiratory and hemodynami...
The impact of left atrial (LA) size on isolation area (ISA) using a 28-mm second-generation cryoballoon (CB) in the acute phase after pulmonary vein isolation (PVI) and the differences of CB from cont...
We evaluated the safety and rhythm-control effectiveness in en bloc isolation of the left pulmonary vein (PV) and appendage conducted as part of the thoracoscopic procedure for bilateral PV isolation,...
A novel real-time lesion size index (LSI) that incorporates contact force (CF), time, and power has been developed for safe and effective catheter ablation. We evaluated the optimal LSI to eliminate g...
Rigid time-based dosing protocol(s) currently used in the clinic for cryoballoon ablation of atrial fibrillation may be inadequate to guide the circumferential and transmural cryothermal energy transf...
Narrowing of the PULMONARY VEIN.
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 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.
A short thick vein formed by union of the superior mesenteric vein and the splenic vein.
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.
