Figure 1 shows the cardiac anatomy relevant for AF ablation when viewed from the anterior (Figure 1A), right lateral (Figure 1B), left lateral (Figure 1C), and posterior projections (Figure 1D, 1E).64 Viewed from the front, the right atrium (RA) is right and anterior, while the LA is situated to the left and mainly posteriorly, with the right pulmonary veins (PVs) adjacent to the intercaval area of the RA.65,66 Consequently, the plane of the atrial septum lies at an angle to the sagittal plane of the body. The front of the LA and the medial wall of the RA lie just behind the aortic root, separated only by the transverse pericardial sinus. The posterior wall of the LA is just in front of the tracheal bifurcation and the esophagus, with the fibrous pericardium separating the heart from these structures.","tracks":[{"project":"2_test","denotations":[{"id":"28506916-10571372-29307087","span":{"begin":372,"end":374},"obj":"10571372"},{"id":"28506916-10571372-29307087","span":{"begin":372,"end":374},"obj":"10571372"},{"id":"28506916-20025713-29307088","span":{"begin":583,"end":585},"obj":"20025713"},{"id":"28506916-20025713-29307088","span":{"begin":583,"end":585},"obj":"20025713"},{"id":"28506916-22334429-29307089","span":{"begin":586,"end":588},"obj":"22334429"},{"id":"28506916-22334429-29307089","span":{"begin":586,"end":588},"obj":"22334429"},{"id":"T85415","span":{"begin":372,"end":374},"obj":"10571372"},{"id":"T69249","span":{"begin":372,"end":374},"obj":"10571372"},{"id":"T69718","span":{"begin":583,"end":585},"obj":"20025713"},{"id":"T9358","span":{"begin":583,"end":585},"obj":"20025713"},{"id":"T59648","span":{"begin":586,"end":588},"obj":"22334429"},{"id":"T82620","span":{"begin":586,"end":588},"obj":"22334429"},{"id":"T89683","span":{"begin":372,"end":374},"obj":"10571372"},{"id":"T99549","span":{"begin":372,"end":374},"obj":"10571372"},{"id":"T63805","span":{"begin":583,"end":585},"obj":"20025713"},{"id":"T66640","span":{"begin":583,"end":585},"obj":"20025713"},{"id":"T4211","span":{"begin":586,"end":588},"obj":"22334429"},{"id":"T68838","span":{"begin":586,"end":588},"obj":"22334429"}],"attributes":[{"subj":"28506916-10571372-29307087","pred":"source","obj":"2_test"},{"subj":"28506916-10571372-29307087","pred":"source","obj":"2_test"},{"subj":"28506916-20025713-29307088","pred":"source","obj":"2_test"},{"subj":"28506916-20025713-29307088","pred":"source","obj":"2_test"},{"subj":"28506916-22334429-29307089","pred":"source","obj":"2_test"},{"subj":"28506916-22334429-29307089","pred":"source","obj":"2_test"},{"subj":"T85415","pred":"source","obj":"2_test"},{"subj":"T69249","pred":"source","obj":"2_test"},{"subj":"T69718","pred":"source","obj":"2_test"},{"subj":"T9358","pred":"source","obj":"2_test"},{"subj":"T59648","pred":"source","obj":"2_test"},{"subj":"T82620","pred":"source","obj":"2_test"},{"subj":"T89683","pred":"source","obj":"2_test"},{"subj":"T99549","pred":"source","obj":"2_test"},{"subj":"T63805","pred":"source","obj":"2_test"},{"subj":"T66640","pred":"source","obj":"2_test"},{"subj":"T4211","pred":"source","obj":"2_test"},{"subj":"T68838","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"2_test","color":"#cd93ec","default":true}]}]}}
