The ‘Corridor’ procedure (Fig. The large variety of lesion sets, ablation techniques and energy sources already devised [Subsequently, the creation of a complete, contiguous ‘box’ lesion set around the orifices of the pulmonary veins connected with additional lines to prevent propagation to the left atrial appendage, the isthmus of the left atrium, coronary sinus and the right atrium (Fig. They hold the secret to appropriate functioning of the circulatory and cardiovascular system.As part of the pulmonary blood circulation they carry oxygenated blood back to the heart, rather than the veins of the systemic blood circulation which bring deoxygenated blood.An uncommon genetic defect of the pulmonary veins can cause them to drain into the pulmonary blood circulation in entire or in part, this is referred to as a total anomalous pulmonary venous connection, or partial anomalous pulmonary connection, respectively.Two primary pulmonary veins emerge from each lung hilum, getting blood from three or four bronchial veins each and draining into the left atrium. The pulmonary veins are the veins that transfer oxygenated blood from the lungs to the heart – it is a main function of the veins. The two pairs of cardiac veins join to form the common cardinal vein (sinos venosus).Configuration of the arterial and venous poles of the developing embryo at 22–23 days (middle of fourth week).

In other words, the pulmonary myocardium covering the pulmonary veins and the outer wall of the LAA joins the cardiac mass after the atrial septation stage, and thus is temporally separate from the development of the rest of the atrial mass, particularly the rest of the left atrium. ERS/ESTS/EACTS/ESTRO guidelines for the management of malignant pleural mesothelioma They are: right inferior left inferior right superior left superior The isthmus of the right atrium is continuous with and composed of the same type of myocardium as the rest of the right atrial wall. Essential lines for successful isolation of the LAA: (1) a complete box lesion encircling the pulmonary veins; (2) lesion at the base of the left atrial appendage, with or without excision; (3) connecting lesion; (4) left atrial isthmus lesion; (5) ablation lesion of the coronary sinus (cryoablation) plus or minus and (6) septal lesion.Essential lines for successful isolation of the LAA: (1) a complete box lesion encircling the pulmonary veins; (2) lesion at the base of the left atrial appendage, with or without excision; (3) connecting lesion; (4) left atrial isthmus lesion; (5) ablation lesion of the coronary sinus (cryoablation) plus or minus and (6) septal lesion.The genesis and perpetuation of AF are complex and multifactorial, involving genetic, signalling, developmental and remodelling processes, which are reflected in the variability of presentation and clinical course. [The posterior part of the left atrium incorporating the pulmonary vein ostia (LAA) exhibits distinct developmental, anatomical, histochemical and electrophysiological characteristics, as a result of being under distinctly different genetic and transcriptional influences from other areas of the atrial chambers. Technically, RFCA has several procedural variations, understanding the common features and challenges are important for both pre-RFCA and post-RFCA computed tomography ( CT ) evaluation. Only after development of the interatrial septum does the common pulmonary vein join the left atrium and becomes incorporated in its wall. Left atrial anatomy, atrial fibrillation burden, and P-wave duration-relationships and predictors for single-procedure success after pulmonary vein isolation Europace . The two left lobar veins may be united as a single pulmonary vein in about 25% of people; the two right veins may be united in about 3%.

This was associated with an unacceptably high rate of pacemaker dependency. Prevalence, age distribution, and gender of patients with atrial fibrillation. Background: Verification of pulmonary vein isolation (PVI) is challenging because of the coexistence of PV and far-field potentials in bipolar electrograms recorded at the left atrial-pulmonary vein (LA-PV) junction.
