Specific Aim: This prospective randomized study aims to compare the impact of three different catheter ablation approaches on long-term procedure outcome in terms of arrhythmia recurrence ...
In this prospective randomized study, we aim to compare the rate of PV reconnection following PVAI performed at different energy settings (30 Watts vs 40 Watts) where dormant PV conduction...
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...
Investigator initiated, randomized controlled trial of two radiofrequency (RF)ablation protocols currently performed in the electrophysiology lab, but have not been studied prospectively t...
Consecutive patients with paroxysmal AFib scheduled to undergo pulmonary vein isolation either with radiofrequency (RF) or cryoballoon will be included. Left atrial appendage emptying flow...
The objective of this study was to evaluate the long-term efficacy of FIRM ablation with PVAI vs PVAI plus posterior wall isolation (PWI) and non-PV trigger ablation in persistent (PeAF) and long-stan...
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,...
The Duration of the Amplified Sinus-P-Wave Identifies Presence of Left Atrial Low Voltage Substrate and Predicts Outcome After Pulmonary Vein Isolation in Patients With Persistent Atrial Fibrillation.
Left atrial (LA) low-voltage substrate (LVS) potentially slows intra-atrial conduction, which might identify patients at risk for arrhythmia recurrence following pulmonary vein isolation (PVI).
Catheter ablation strategies for non-paroxysmal atrial fibrillation (NPAF) are in varied forms. The mechanisms that circumferential pulmonary vein isolation (CPVI) alone could achieve success in some ...
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 compression of ILIAC VEIN that results in a decreased flow in the vein and in the left LOWER EXTREMITY due to a vascular malformation. It may result in left leg EDEMA, pain, iliofemoral DEEP VENOUS THROMBOSIS and POSTTHROMBOTIC SYNDROME. Compression of the left common ILIAC VEIN by the right common ILIAC ARTERY against the underlying fifth LUMBAR VERTEBRA is the typical underlying malformation.
Narrowing of the PULMONARY VEIN.
