부승모판막(accessory mitral valve tissue)은 매우 드문 선천성 심장병이며, 좌심실 유출로 협착(left ventricular outflow tract obstruction)의 드문 원인 중의 하나이다. 심수축기시에 부승모판막이 낙하산처럼 펴지며 잡아당기고 있어서 앞승모판막첨(anterior mitral valve leaflet)이 좌심실 유출로 쪽으로 당겨지면서 유출로 협착을 유발한다. 저자들은 본 환자에서 심초음파 검사를 통해 대동맥판막하 협착(subaortic stenosis)의 진단 하에 수술을 하였으며, 수술 중 부승모판막을 화인하고 수술을 하였기에 증례 보고를 하는 바이다.

Double mitral valve orifice is an unusual congenital abnormality, and is rarely of clinical importance. That abnormality not produce hemodynamic deficits, but it has been associated with other congenital heart diseases, especially atrioventricular canal defects, and so it is surgically important condition. After the first report by M.S. Greenfield in 1876, there are only a few reported cases all over the world. We experienced two cases of double mitral valve orifice with atrioventricular canal defect. The small accessory mitral orifice was placed in anterior mitral leaflet as a hole type in both cases. The A-V canal defects are corrected with a one patch technique, but the accessory orifices are left unclosed because there were no mitral regurgitations through the orifice. On the 4th postoperative day, the patients have been performed echocardiography; both had no mitral regurgitation. Both of patients are now being follow-up and we find no specific problems. A small accessory mitral orifice may be left unclosed and rarely produce significant regurgitation, conclusively.

In a 3-year-old Samoyed, aortic bulging was found on radiography during a general check-up. On echocardiography, turbulent flow was found in left ventricular outflow tract (LVOT) with high velocity (6.1 m/s). A linear structure was attached to the interventricular septum and connected to the chordae tendineae reaching the papillary muscle. A part of the structure moved during cardiac cycle, similar to mitral motion. This dog was diagnosed with LVOT obstruction caused by accessory mitral valve tissue (AMVT). This is the first report of AMVT in veterinary medicine. AMVT should be considered as a possible cause of LVOT obstruction in dogs.

We report a case of double orifice mitral valve complicating a partial atrioventricular septal defect.The preoperative diagnosis was suggested by a characteristic angiographic and echocardiographic findings but the correct diagnosis of double orifice mitral valve itself was proven by open heart surgery. The smaller accessory mitral orifice was located in the left lateral leaflet and was left untouched. The A-V septal defect was closed with Gore-Tex patch and localized tricuspid annuloplasty was done using Gore-Tex tubular graft for correction of severe tricuspid regurgitation. The anterior mitral cleft left intact had mild mitral regurgitation on postoperative echocardiography.Postoperative course was uneventful and the patient was discharged 2 weeks later.

1993년 10월부터 1996년 2월까지 9명의 Wolfr-Parkinson-White증후군을 가진 환자에서 우회로의 외과적 절제술을 시행하였다. 수술적응례를 살펴보면 도자절제술이 실패한 경우가 6례, 우회로가 2개 있었던 경우와 도자절제술중 도자 말단부위가 부러졌던 경우가 1례씩 있었으며, 나머지 1례는 승모판막재치환술이 필요했던 경우이다. 수술사망은 없었으며 술후합병증은심낭삼출액과 창상감염이 각각 1례씩 있었다. 모든 환자에서 술후 심전도검사 및 전기생리검사를 통해 우회로가 완전 절제되었슴을 확인할 수 있었으며 추적 관찰기간중 인맥을 보인 환자는 없었다. 이상의 결과로 Wolfr-Parkinson-White증후군에서 우회로의 외과적 절제는 도자절제술이 실패한 경우, 우회로가 여러개 있는 경우, 그리고 동반된 심질환의 교정을 요하는 경우로 국한되며 수술적응례에서 외과적 절제술은 비교적 안전하고 효과적인 치료방법으로 사료된다.

Cortriatriatum is rare congenital heart disease characterized by the presence of a fibromuscular diaphragm that subdivides the left atrium into a proximal or "accessory" and a distal or "true" left atrial chamber. A 15 year old girl with cortriatriatum underwent surgical correction at the department of Thoracic and Cardiovascular Surgery, Soonchunhyang College in November, 1984. This case was preoperatively diagnosed as a single atrium with functional tricuspid regurgitation But on operation, we found that there were transverse septum in the left atrium through large ASD, low chamber receives the pulmonary veins, and the upper chamber gives rise to the left atrial appendage and leads to the mitral valve. And the anomalous membrane has no fenestrations. We excised completely the anomalous septum, reconstructed atrial septal defect with dacron patch and performed the tricuspid annuloplasty with DeVega method. Postoperative course was uneventful during follow up, during follow up.
