Intraoperative radiofrequency microbipolar coagulation to replace incisions of maze III procedure for correcting atrial fibrillation in patients with rheumatic valvular disease

Abstract

Thus, our modification considerably shortened the time taken for creating the maze in comparison to the Cox's maze procedure and was effective in restoring normal sinus rhythm in 80% of the patients.

Current Perspectives: Rheumatic Atrial Fibrillation

“…37,38 Although initial studies had shown insufficient rates of sinus rhythm restoration (59%) for the Maze procedure in AF associated with rheumatic valve disease, 39 subsequent studies by other investigators have shown comparable conversion rates with acceptable operative risk to that of nonvalvular AF. 36 Patwardhan et al 40 41 have also had similar experience with radiofrequency maze during mitral valve surgery, with a longer follow up of 3 years wherein 77% of patients remained in sinus rhythm. The outcome of surgical maze for atrial fibrillation is similar in rheumatic and non-rheumatic atrial fibrillation in terms of sinus rhythm achievement and restoration of left-atrial function.…”

Intraoperative Hochfrequenzstromablation zur Therapie von Vorhofflimmern Die Berlin-Modifikation

“…Im Vergleich zur Standardtechnik sind keine multiplen Inzisionen im linken Atrium erforderlich, des Weiteren wird eine signifikante Verlängerung der Aortenklemmzeit vermieden. Die angewandte Methode ist eine von zahlreichen Modifikationen der intraoperativen Hochfrequenzstromablation, welche in jüngster Zeit entwickelt wurden [8][9][10][11][12][13][14][15][16]. Wir beobachteten einen relativ hohen Anteil an früh postoperativem Vorhofflimmern.…”

“…Die intraoperative Hochfrequenzstromablation ist ein neuartiges chirurgisches Prinzip zur Behandlung von Vorhofflimmern in Kombination mit Standardherzoperationen [8][9][10][11][12][13][14][15][16]. Es basiert auf dem von James Cox [1] entwickelten und eingeführten Entwurf der MazeOperation.…”

“…Die Applikation von Hochfrequenzstrom ersetzt hierbei die Inzisionen und Nähte der StandardMaze-Technik. Es gibt eine Vielzahl von Modifikationen hinsichtlich der für die Ablation verwendeten chirurgischen Sonden, entsprechend der Art der Applikation (endokardial oder epikardial) und der Anordnung der Maze-Linien [8][9][10][11][12][13][14][15][16].…”

From MAZE to ICE: new concepts and new technologies for surgical ablation of atrial fibrillation

“…Some of these concepts aimed at the partial or complete reproduction of the Maze III lesion line concept while others introduced new treatment strategies based on the growing pathophysiological understanding of atrial fibrillation. [5][6][7] Subsequently, new energy sources such as microwave, cryoenergy, and highly focused ultrasound were introduced to facilitate lesion induction in the atria during cardiac surgery. Recently, Khargi and co-workers published a meta-analysis of a large number of studies reporting the results of surgical ablation of atrial fibrillation using various energy sources for ablation compared with the results of the classical Maze procedure.…”
