Abstract

Backgrounds: Transseptal left atrial approach is used in mitral valve surgery whenever adequate surgical exposure cannot be obtained. The probability of emergence of arrhytmias causes reluctancy to apply these methods. The changes of QT intervals in ECG may predict arrhytmias in most cases. Methods: We compared the changes in QT intervals between two groups in which transseptal and conventional left atrial approaches were used. Transseptal and conventional atriotomy groups were comprising of 16 and 19 patients respectively. Only the patients with sinus rhythm who were not using any of antiarrhymic agents were included in this study. QT intervals were revised by using Bazett formula and corrected QT dispersion values were calculated for each patients.Results: Most QT intervals were prolonged on the first postoperative day but these values returned to the baseline on the sixth day. There was not any significant difference between the two groups in accordance with the atrial and ventricular arrhytmia, using antiarrhymic drug and of rhytmic changes.Conclusions: In this study we did not find any difference in relation with corrected QT dispersion values between conventional and the transseptal approach in mitral valve surgery which we cannot obtain adequate exposure.

Özet

Amaç: Mitral kapak cerrahisinde yeterli cerrahi görüş sağlanamadığı durumlarda transseptal yaklaşım bir alternatif olarak kullanılmaktadır. Alternatif yaklaşımlarda postoperatif aritmilerin ortaya çıkabileceği düşüncesi, bu yöntemlerin tercih edilmemesine ve yeni arayışlara sebep olmuştur. Materyal ve Metod: Elektrokardiyografide QT intervallerinin değişkenliği aritmilerin oluşması yönünden öncü bir belirtidir. Transseptal ve konvansiyonel sol atriyotomi yaklaşımı kullandığımız iki grupta QT interval değişikliklerini karşılaştırdık. Transseptal ve konvansiyonel grup sırası ile 16 ve 19 hastadan oluşuyordu. Çalışmaya sadece sinus ritminde olan hastalar dahil edilmiş ve daha önce antiaritmik kullanan hastalar çalışmaya alınmadı. Elektrokardiyografideki QT süreleri Bazett formülü ile değiştirildikten sonra düzeltilmiş QT dispersiyonu (QTcd) her hasta için ayrı ayrı hesaplandı.Bulgular: Hastaların postoperatif ilk günde QT sürelerinde artış olduğu, fakat bu sürelerin postoperatif altıncı günde preoperatif değerlere geri döndüğü tespit edildi. İki grup arasında atriyal ve ventriküler aritmi, antiaritmik kullanımı, ritm değişiklikleri yönünden anlamlı farklılık bulunmadı.Sonuç: Yaptığımız çalışmada özellikle mitral kapak cerrahisinde yeterli görüş sağlanamayan durumlarda kullanılan bir yöntem olan transseptal yaklaşım ile konvansiyonel sol atriyotomi yapılan hastalarda düzeltilmiş QT dispersiyonu değerleri arasında bir fark ortaya çıkmamıştır.
