All patients underwent pre-procedural cardiac computer tomography evaluation to delineate the left atrium and pulmonary vein anatomy.
Echocardiogram revealed situs ambiguous, levocardia, interrupted inferior vena cava (IVC), dilated coronary sinus with Left superior vena cava (LSVC), all Pulmonary veins draining via an ascending vein to right superior vena cava (RSVC), dilated RA + RV and Rt to Lt shunting across unrestricted ASD.
Left pulmonary veins were seen draining into left atrium and similar venous drain from right side was found to be absent (fig.
Surgical correction of PAPVC varies according to the type of underlying anomaly, however the basic principle remains the segregtion of systemic and pulmonary circulation either by communicating the anomalous pulmonary vein to the left atrium directly or indirectly rerouting through baffle into left atrium.
Atrial tachycardia after circumferential pulmonary vein ablation of atrial fibrillation: Mechanistic insights, results of catheter ablation, and risk factors for recurrence.
Pulmonary vein isolation (PVI) has become an accepted treatment for paroxysmal AF over the last 15 years following the discovery by Haissaguerre et al, (1998), that paroxysmal AF was the result of triggered and ectopic electrical activity arising from the pulmonary veins that bring blood back from the lungs to the left atrium of the heart.
In total, 3775 patients were included in 4 retrospective studies (n = 845), 5 prospective nonrandomized studies (n = 283), and two prospective randomized studies (n = 2650): the ADVICE trial (Adenosine Following Pulmonary Vein Isolation to Target Dormant Conduction Elimination, n = 534) and the UNDER-ATP trial (UNmasking Dormant Electrical Reconduction by Adenosine Triphosphate, n = 2113), which will be analyzed separately [9-11].
After that common pulmonary vein arises from the left atrium and grows toward the lung, it develops a connection with the pulmonary vascular bed, with disappearing of the primitive connections with systemic veins.
The interlobular septal thickening, bronchial wall thickening, and ground glass opacities likely reflect both pulmonary vein hypertension and engorged lymphatics.
Once they've gotten from the right to the left side of the heart, they use a radiofrequency catheter at the origin of those pulmonary veins and they burn the tissue at the entrance of the pulmonary vein.
The likely explanation lies in the fact that electrophysiologists at the Austin center routinely extended their pulmonary vein antrum isolation to the posterior wall and performed empiric isolation of the superior vena cava in all patients.
