This study was aimed to obtain the anatomical information on the location of ostia of left and right coronary artery in 3 weeks old and 6 months old hybrid swine. The each intercommissural distance of 6 months group was twice than 3 weeks old group. The largest sinus was right aortic sinus followed by left and posterior sinus. All left coronary artery ostia in left aortic sinus were located near the right aortic sinus as well as lower than the ostia of right one. Most of the right coronary artery ostia were located at the level of supravalvular ridge of right aortic sinus. In addition the right ostia had more variation than left ones. Comparing to the sites of 3 weeks old pigs, the sites of the right ostia in 6 months group were more variable. These data suggest that the locations of coronary ostia were different with the sites of human's, and changes of the location may be occurred during the growth.

The selection of an appropriate surgical technique for repair of aneurysm of the ascending aortia with aortic insufficiency is unsettled. The etiology of the disease process has been the best indicator for the type of repair. Placement of a supracoronary graft[seperate graft and valve] is a compromise if the coronary ostia are displaced cephalad by the aneurysm, where as insertion of a valved conduit is difficult and unnecessary if the coronary ostia are normally placed. A 53 year old female patient underwent primary repaiar of proximal dissected layer and aortic valve replacement with 24mm carbomedics, The operative findings consisted of a supravalvular intimal tear, cicumferential dissection, dilated aortic annulus and normal position of coronary ostia. She is good physical activity now llmonths posoperatively.

The surgical treatment of annuloaortic ectasia falls into two basic categories, depending on the management of the coronary artery ostia and the sinus of Valsalva. The conventional method, first suggested by Groves, Wheat and their associates, employs a supracoronary graft for the treatment of aneurysm and conventional valve replacement. A more radical approach, that of Bentall and DeBono, uses a valve conduit from the aortic annulus to the distal extent of the aneurysm. This latter technique requires reimplantation of the coronary artery ostia for reestablishment of coronary artery blood flow. Recently we experienced a case of annuloaortic ectasia to which we applied the Bentall operation with the good postoperative result, and now we report this with literature review.

The aneurysmal dilatation of ascending aorta with the aortic regurgitation presents typical surgical problems. Over the years, various surgical procedures had been used for the management of the dilated segment of sending aorta and the aortic regurgitation. The surgical technique Is still in the state of evolution. The one method is the super coronary replacement of the ascending aorta with vascular graft and replacement of the aortic valve with preservation of the coronary ostia as advocated by Miller and his colleague at Stanford University, so called conventional technique". The other is the replacement of aortic valve and the dilated segment of the ascending aorta using a composite graft and transplantation of the coronary ostia as described by Bentall and DeBono in 1968. The controversy appears to evolve around 3 technical problems. One is bleeding from the grafted area. Two is later development of the aneurysmal dilatation of the subcoronary aortic wall when non-composite graft is employed. Three is a management of the coronary arteries. The purpose of this article is to present our experience with 7 cases of annuloaortic ectasia in whom both of these surgical techniques at that employed and to review some of the problems that encountered during the management of these patients .

A case of Annuloaortic Ectasia associated with Marfan syndrome and mitral regurgitation is treated surgically by Bentall`s method and mitral annuloplasty. The Annuloaortic Ectasia is frequently accompanied with Marfan syndrome, its definition is simply explained as the following; the marked dilatation of the sinuses of Valsalva and the aortic annulus as well as the huge aneurysm of the ascending aorta. As the operative finding, the intimal tearing was shown as circular and the both coronary ostia were changed the position into high up. The patient was taken a corrective operation replacing the ascending aorta and aortic valve with a composite graft[St. Jude medical valve 29mm, woven Dacron tubular graft 31mm]. The both coronary ostia were reimplanted on the graft with 4-0 prolene by continuous suture. Mitral annuloplasty was performed. After the operation, the patient developed both spontaneous pneumothorax, he improved state by the closed thoracostomy. He has been doing well, postoperatively.

A case of Annuloaortic Ectasia associated with Marfan syndrome was treated by replacement of aorta and aortic valve with a valved conduit. A 26 years old man had suffered from palpitation and precordial pain. He had stigmata of Marfan`s syndrome. Aortogram and 2-D echocardiogram confirmed aneurysm of the ascending aorta with aortic insufficiency. Surgery was performed under the moderate hypothermia to 28oC. There was marked dilatation of the aortic annulus as well as sinus of Valsalva, with displacement of the coronary ostia. Aortic valve and aneurysm was replacement with 25mm, woven Dacron tubular graft, to which a 25mm, S.T. Jude Medical valve had been previously sutured. Right & left coronary ostia were anastomosed to the graft with the use of 3O Nylon pledget suture. The patient had a satisfactory post operation period with out specific complication.

심장 CT 혈관 조영 영상은 심혈관의 전체 해부학 구조를 3D 로 보여줄 뿐 아니라 병변의 정보를 제공하기 때문에 관상동맥 질환 진단 및 치료에 많이 사용되고 있다. 하지만 영상의 방대한 크기로 인해 수동으로 정보를 추출하는 데는 한계가 있어 자동으로 심혈관을 정확하게 추출하는 연구들이 활발히 진행되고 있다. 심혈관 자동 추출 알고리즘을 개발하는데 있어 심혈관의 시작점인 상행대동맥의 심문을 검출하는 방법은 필수적인 부분이다. 본 논문에서는 심혈관의 시작점인 심문을 분할하는 방법을 제안한다. 첫째, 상행대동맥의 크기와 위치를 고려한 허프변환으로 대동맥 초기영역을 검출한다. 둘째, 초기영역을 기반으로 탐색범위를 줄일 수 있도록 관심 볼륨 영역을 설정한다. 셋째, 지오데식 활성외곽선 모델을 기반으로 정제된 대동맥 영역을 검출한다. 마지막으로 검출된 대동맥 영역에서 심문을 분할한다. 제안방법의 평가를 위해 20 개의 심장 CT 혈관 조영 영상에서 전문가가 수동으로 표기한 시작점과 비교 분석하였다. 실험 결과 제안방법을 통해 시작점이 제대로 추출 됨을 확인할 수 있었다.

We have experienced two cases of ascending aorta aneurysm with aortic regurgitation in Marfan`s syndrome. There were abnormal findings in cardiovascular system associated with abnormalities of skeletal systems. They had total replacement of the ascending aorta and aortic valve with Bjork-Shiley`s aortic valve composite graft and reimplantation of coronary ostia on the graft. Their postoperative courses were uneventful and discharged with good clinical results for follow up.

Two young male patients were operated on for the Marfan syndrome complicating ascending aortic aneurysm and a moderate degree of aortic regurgitation. We replaced the ascending aorta and aortic valve with Bjork-Shiley aortic valve composite graft and implanted the coronary ostia in the sides of the graft directly. Postoperatively, the atrial fibrillation occurred in one case and the other had uneventful course. They showed improvement in activity at follow-up.

A 64 year-old male patient with annulo-annulo-aortic ectasia[AAE] due to cystic medial necrosis was successfully treated with Cabrol operation with Cabrol trick. The technique consist of implantation of a composite valve graft within the aneurysmal sac with reattachment of the coronary ostia using a separate, small tube graft and creation of a communication between the closed perigraft space and right atrium for bleeding control. The patient had a postoperative gastrointestinal bleeding but successful recovery was achieved eventually.
