    [47] using multislice computed tomography analyzed the anatomical characteristics of three different endocardial lines in the left atrium anteromedial (AM), anterolateral (AL), and posterolateral (PL) from right superior, left superior, and left inferior PV, respectively.
    It is important to stress the fact that the CS at the level of the A-V sulcus, clearly is not intramural, and its striated myocardial muscle is integrated into the CS and not into the left atrium. Coakley et al., in various animal species and in three human hearts, found that some of the muscle fibers related to the CS and the oblique vein, resemble fibers of the sinus and A-V nodes.
    Video 5: an echocardiogram in apical four-chamber view showing a large myxoma in the right ventricle (causing obstruction of the blood flow across the tricuspid valve), a myxoma in the left ventricle, and another myxoma in the left atrium.
    For right sided PAPVC to SVC and sinus venosus ASD, patch baffling has been described between the right sided anomalous pulmonary veins and left atrium along with with an additional patch to augment SVC.9 Warden technique has also been suggested which involves SVC reimplantation into right atrial appendage along with patch baffling of SVC orifice.10,11 The idea is to eliminate the intra atrial communication without narrowing of pulmonary vein or SVC and avoiding any injury to sinus node.
    Inclusive and Exclusive Criteria: Patients who had valvular heart disease in combination with atrial fibrillation, aged between 18 and 70 years, had inner diameter of long-axial section of the left atrium not larger than 70 mm, and had LVEF not smaller than 45% were enrolled.
    Based in Israel, the company's TSP Crosser is an advanced transseptal puncture system with a built-in steering mechanism, which is indicated in procedures where access to the left atrium via transseptal technique is desired, including Mitral Valve Repair, Mitral Valve Replacement, Paravalvular leak closure, LAA Closure as well as EP Ablation treatments.
    In that group, 47% of the dogs (9/19) had an increased left atrium (LA/Ao>1.37) documented on the echocardiogram, i.e.
    Studies have reported about the compression related to the right atrium (1), the left atrium (2), and the right ventricle (3) caused by the aortic aneurysm.
    Through a median sternotomy, on moderately hypothermic cardiopulmonary bypass with aortic and bicaval cannulation, the left atrium was entered through a right atriotomy and transseptal incision.
    Multidetector computed tomography (MDCT) can help visualize the anatomy of the left atrium as well as the number, localization, and diameters of PVs (6-8).
    In a study, PTMC procedure gave a high rate of success, with 93.6% of the patients achieving MVA >1.5 cm2.19 The insignificant increase in the size of left atrium in a few cases can only be explained on the ground that echo is a subjective tool and even minimal changes in probe placement from different window sites in the same person some time can result into different size readings.
