and the esophagus: implications for left atrial catheter ablation," Circulation, vol.
The striated muscle fibers that form the body of the CS musculature have endocardium on their inner surface, epicardium on their external surface, and bear no anatomic relationship to the left atrium

For bilateral PAPVC, in one patient atrial septal defect was enlarged and coronary sinus was unroofed and single autologous patch was used to reroute the pulmonary veins and coronary sinus into left atrium
. However, in second patient right pulmonary vein was rerouted by two pericardial patches and left pulmonary vein draining into vertical vein was rerouted by side to side anastomosis between vertical vein and left atrial appendage.
The observation group included 36 males and 29 females; and their average age was (55.8+-6.4) years; atrial fibrillation has lasted (5.5+-2.2) year), which was determined as long-standing persistent; the diameter of the left atrium
was (57.4+-7.0) mm, and the left ventricular ejection fraction (LVEF) was (60.4%+-5.0%).
Left heart treatment company Transseptal Solutions Ltd revealed on Thursday the receipt of the US FDA's 510(k) clearance for the TSP Crosser Transseptal Access System for the precise and efficient access to the left atrium
for transcatheter left atrium
In this study, we considered 1.37 as the cut-off for increased left atrium
(PRADA et al., 2012).
Parasternal long axis and four-chamber images in the echocardiography showed aortic dissection and compression of the left atrium
and the left ventricle caused due to an aneurysm when the patient was evaluated for the first time (Figure 1a).
The left atrium
was dilated and almost completely occupied by the mass, which partially obstructed the mitral orifice during diastole.
Therefore, detailed knowledge of pulmonary venous anatomy and relationships between the PVs and the left atrium
is highly necessary for mapping and ablation treatment (3).

He noted that the patient was in need of an operation for a year ago by a specialist team, as the subsequent analysis showed that there is a large thrombus within the left atrium
constantly moving with each heartbeat and with a risk of separation of this thrombosis and going to the brain causing a large clot, pointing to carrying out an urgent operation to extract the thrombus from the inside of the left atrium
and changing mitral and aortic valves, adding now the patient is in a stable condition and can go out home within a few days.
