The company said the HeartLight System is a visually guided laser balloon technology for controlled and consistent pulmonary vein
isolation (PVI) treatment of AF.
Wilkoff also notes that high blood pressure and kidney disease can contribute to poor pulmonary vein
health, including the formation of blood clots in your pulmonary veins
Commonly, the surgical portion of the hybrid approach is prior to the transvenous portion in a staged approach, thereby, in principle, allowing the electrophysiologist to confirm epicardial linear lesions and pulmonary vein
isolation (PVI); in addition to decreasing the burden of additional endocardial lesion sets needed to be applied by the electrophysiologist to achieve procedural end-points.
Variation in systemic and pulmonary vein
anomalies anatomic pattern and clinical presentation can present a diagnostic dilemma which can have significant implications on its course and outcome.
An anomalous right pulmonary vein
draining into the systemic venous circulation either below or above the diaphragm most commonly to the inferior vena cava, occasionally into the hepatic vein, portal vein, azygos vein, coronary sinus or the right atrium.
4%) cases had right pulmonary vein
draining into right atrium.
Entrainment mapping at the anterior wall of LA by a pulmonary vein

isolation (PVI) using radiofrequency ablation is a well-known and accepted option for the treatment of drug resistant paroxysmal atrial fibrillation (PAF) (January et al, 2014).
Their topics include indications for catheter and surgical ablation, equipment options, pre-procedure preparation, intracardiac ultrasound, the magnetic resonance imaging definition of the atrial substrate, interpreting circular mapping catheter recordings, circumferential ablation with pulmonary vein
isolation guided by lasso catheter, limited ablation for persistent atrial fibrillation using pre-procedure reverse remodeling, and charting long-term success and the challenge of monitoring outcomes.
Catheter ablation is an effective treatment for atrial fibrillation (AF); the cornerstone of this procedure is durable and effective pulmonary vein
Although PAPVR is often asymptomatic, its recognition may be important because the variability of pulmonary vein
drainage to the left atrium may lead to a left-to-right shunt, can be significant in affecting the success of catheter ablation in patients with atrial fibrillation, and should be considered in the preoperative evaluation of patients with lung cancer .
During the two-hour surgery, the tumour proved to have swung to the lower pulmonary vein
