초록

배경: 판막성형술을 포함한 승모판막 수술에 있어서 충분한 승모판의 노출은 필수적이다. 최근 확장된 경중격 절개술은 수술 후 동결절동맥의 손상에 기인한 율동이상의 가능성에도 불구하고 특히 재수술이거나 좌심방 크기가 작을 때 유리한 술식으로 알려져 있다. 대상 및 방법: 저자등은 중격절개만 시행한 10례 (I 군)와 절개를 확장한 25례(II 군)를 대상으로 수술 전후의 조건 및 결과를 비교 분석하였다. 결과: 양 군의 나이, 성별, 그리고 수술 전후의 NYHA 기능적 분류, 좌심방 크기, 좌심실 기능의 변화는 차이가 없었다. II 군에서 과거 개심술을 시행 했던 환자의 재수술 빈도가 높았고 나중에 회복된 수술 후 조기 율동 이상이 3명의 환자에서 나타났으나, I군에서는 없었다. 결론: 따라서 확장된 경중격절개술은 수기상 동결절 동맥의 손상에 기인한 술 후 조기 이상 율동이 나타날 수 있으나 나중의 결과에는 차이가 없으므로 경중격절개술로 시야 확보가 불충분한 경우에 언제라도 적용할 수 있으리라 판단된다.

Background: Adequate exposure of the mitral valve is a prerequisite for mitral procedures including the repair. An extended transseptal approach in mitral valvular operations is known to have certain technical advantages in recent years because of the anatomic posterior location of the mitral valve, especially in reoperations and in the presence of the small atrium in spite of the possibility of arrhythmia due to injury of sinus nodal artery. Material and Method: We compared the preoperative status, operative, and postoperative factors among patients in two study groups, transseptal only (Group I, n=10) and extended transseptal approach(Group II, n=25). Result: There were no differences in age, sex, NYHA functional class, left atrial size, and left ventricular function. The incidence of the redo-operation was high and early postoperative arrhythmia, which was improved later, appeared in 3 patients in Group II, but not in Group I. Conclusion: We believe that atrial septal incision could be extended up to the atrial roof whenever exposure of the mitral valve during a transseptal approach is inadequate because the late results were similar.
