Successful combined operation for mitral stenosis and atrial fibrillation

Radiofrequency modified maze in patients with atrial fibrillation undergoing concomitant cardiac surgery

“…Excellent results have been described for the surgical treatment of chronic AF associated with organic heart disease at the expense, however, of considerable prolongation of time required for cardiac arrest and cardiopulmonary bypass. 4,16 In an attempt to reduce procedure time and to simplify the surgical procedure, modifications of the original maze procedure 8 have been developed, including the use of cryoablation and changes in atriotomies 17 and application of RF energy alone 18 or with cryoablation. 19 Treatment of AF by application of contiguous RF-induced lesions in the atria are based on the concept of preventing functional re-entrant circuits 18,20 or to eliminate anatomically determined circuits.…”

Surgery for atrial fibrillation using radiofrequency catheter ablation

“…Excellent results have been described for the surgical treatment of chronic AF associated with organic heart disease at the expense, however, of extensive atrial incisions and suturing and greater blood loss, as well as longer cardiac arrest. 11,12 In an attempt to reduce the procedure time and to simplify the surgical technique, modifications of the original maze procedure have been developed, 13 including the application of RF energy. 14 Heat propagation is based on resistive and passive mechanisms.…”

"Cox/Maze-III-Operation" als chirurgische Therapie des chronischen Vorhofflimmerns während Mitralklappen- und ASD-II-Operation

“…der Patienten. Diese Ergebnisse gehen mit den in der Literatur veröffentlichten Daten einher, obwohl die Anzahl der kombinierten Herzoperationen dieser Art noch gering ist (2,8,12,16,18). In der vorliegenden Studie konnten wir bei 15 von 16 Patienten (94 %) im mittleren Nachbeobachtungszeitraum von 14 Monaten (1-24 Monaten) einen stabilen SR erzielen.…”
