  • ATS 인공판막을 이용하여 심장판막 치환수술을 시행받은 100명의 연속적인 환자를 대상으로 조기 성적 과 외래 추적 결과를 분석하였다. 또한 수술 후 시행한 도플러 심에코 검사 결과를 통하여 이 판막의 혈역학 적 특성을 살펴보았다. 환자들의 평균 연령은 48.6세였으며 총 124개의 판막이 치환되었다. (승모판막 71, 대 동맥판막 46, 삼첨판막 7) 가장 많이 사용된 크기는 승모판막에서는 27 mm(40.8%), 29 mm(35.2%)였고 대동 맥판막에서는 23 mm(30.4%), 21 mm(28.3%)였다. 수술후 조기 사망은 1례도 없었고 총 950 patientmonths의 외래추적이 이루어졌다(추적율=99%). 만기 사망도 없었으며 혈전-색전증이나 판막의 구조적 결합에 의한 합병증은 발생하지 않았다. 2명의 환자가 각각 Valsava동의 파열과 심내막염에 의한 대동맥 인공판막 dehi nce로 재수술을 받았고 고혈압을 가지고 있던 환자 1명에서 두개내 출혈이 발생하였다. 도플러 에코검사 결과 판막 전후의 최대 및 평균 압력차는 승모판막의 경우 각각 평균 6.9 mmHg, 2.6 mmHg였고 대동맥판막의 경우 26.4 mmHg, 14.2mmHg였으며 승모판막의 평균 개구부 면적은 2.7 cm2였다. 27-mm이상 크기\ulcorner 승모판막에서는 판막크기에 따른 압력차나 개구부 면적의 차이가 없었으나 대동맥판막에 서는 판막크기의 감소와 압력차의 증가간에 유의한 상관관계가 있었다. 19-mm와 21-mm 대동맥판막의 경우 는 최대 및 평균 압력차가 각각 52.2 mmHg, 26.9 mmHg 및 27.1 mmHg, 13.3 mmHg였다. 상기 연구결과로써 ATS 인공판막의 조기 임상 성적은 만족스러운 것으로 결론지을 수 있으며 혈역학적 특성은 기존의 동일 유형 판막들과 비교하여 더 우수하다고 할 수는 없으나 차이가 없는 것으로 판단된다.

  • 활동성 심내막염의 외과적 치료시기에 대해서는 아직 논란의 여지가 있지만 최근에는 조기 수술에 대한 좋은 보고들이 있다. 이에 저자들은 활동성 심내막염에 대한 수술 결과를 수술 전 항생제 사용기간에 따라 분석해 보았다. 대상 및 방법 : 1995년 3월부터 2001년 10월까지 활동성 심내막염으로 삼성서울병원 흉부외과에서 수술 받은 환자 51명에 대해서 후향적으로 분석을 하였다 남녀 성비는 39 : 12였고, 평균 연령은 44.5$\pm$17.8세(범위 13~74세)였다. 감염된 판막은 승모판막이 17례(33.3%), 대동맥판막이 15례(29.4%), 승모판막 및 대동맥 판막이 12례(23.5%), 삼첨판막이 5례(9.8%)였다. 그 중 인공판막 심내막염이 10례(19.6%)였다. 감염 균주는 포도상구균이 19례(37.3%), 연쇄상구균이 17례(33.3%), 장내구균이 3례(5.9%), 진균이 3례(5.9%), 기타균이 5례(9.8%), 균주가 동정되지 않은 경우가 6례(11.8%)였으며, 4례(7.8%)에서는 2가지 균주가 동정되었다. 이 환자들을 수술 전 항생제 사용기간에 따라 2군으로(A : 7일 이하, B : 8일 이상) 나누어 두 군간의 수술 성적을 비교하였다. 결과 : A군은 16명이었으며 B군은 35명이었다. 판막륜 재건을 A군에서는 10례(62.5%), B군에서 10례(28.6%)로 통계적으로 유의한 차이가 있었다(p < 0.05). 수술 후 조기 사망은 B에서 1례 있었다. 2명을 제외한 49명(96.1%)의 환자에서 추적관찰이 이루어졌으며, 평균 추적관찰 기간은 28.7 $\pm$ 23.6개월로 재발은 A군에서 1례, B군에서 2례 있었다. 만기 사망은 B군에서 3례에서 있었다. 재발률과 생존율 모두 두 군에서 통계적으로 유의한 차이가 없었다. 결론 : 활동성 심내막염에서 조기 수술하는 경우도 수술 전항생제를 충분히 사용한 경우와 비슷한 좋은 결과를 보여 활동성 심내막염의 조기 외과적 치료가 효과적으로 감염을 제거할 수 있다고 사료된다.

  • We analysed 60 consecutive patients who got Senning operation for transposition of the great arteries [TGA] with or without ventricular septal defects [VSD]. There were 41 simple TGA [group I] and 19 TGA with VSD [Group II], the operative mortality was 20 % [in group I 4.9 %, group II 52.6 %]. Among the survivors [n=48], the mean follow-up period was 7 years [range, 1 year to 13.5 years] and the actuarial survival rate at 13 years were 95 % in group I and 42 % in group II. Preoperative high left ventricular pressure and high pulmonary arterial pressure affected the surviving [p<0.01]. There occurred various type of arrhythmia like junctional rhythm, first degree atrioventricular [AV] block, sick sinus syndrome and complete AV block, and we inserted 2 permanent pacemakers for these patients. The incidence of arrhythmia were 28.2 % [11/39] in group I and 55.6 % [5/9] in group II, and the actuarial freedom from arrhythmia at 13 years after operation was 66 % [71 % in group I, 44 % in group II]. Increased aortic cross clamping time had affected the development of arrhythmia [p<0.05] which meant the complexity of the operation. The total incidence of left ventricular outflow tract obstruction [LVOTO] was 31.3 % [15/48], but only 3 patients [6.25 %] showed the significant gradient requiring reoperation. The pulmonary venous pathway obstruction [PVO] were found in 3 patients, all in group I, and among them only one required the reoperation. The estimated freedom from PVO was 89 % at 13 years [87 % in group I, 100 % in group II], but we couldn`t find any significant systemic venous obstruction in our series. There occurred 27.1 % [13/48] mild degree tricuspid valve regurgitation without necessary surgical correction. We experienced 14.6 % [7/48] reoperation rate: 3 residual VSD, 3 LVOTO, 1 PVO, 3 atrial baffle leakage. For this high incidence of complication rate after Senning operation and high mortality in TGA with VSD, We do not use this kind of surgical modality any more and do the Jatene operation for all the TGA patients since several years ago.

  • Seventy-three patients with isolated total anomalous pulmonary venous connection the patients associated with other major cardiac anomalies such as single ventricle, DORV[Double Outlet Right Ventricle and large VSD[Ventricular Septal Defect were excluded were underwent surgical repair from January 1980 through October 1993. There were 45 boys and 28 girls. The mean age at operation was 19.9 months[range 6 days to 24 years and mean body weight was 7.1kg[range 2.6kg to 45kg . The anomalous locations of connection were supracardiac in 38, cardiac in 21, infracardiac in 5, and mixed in 9. In 38 patients[52% , the venous drainage was obstructed. The obstruction ratios according to the connection type were as follows: 53%[28/38 in supracardiac, 52%[11/21 in cardiac, 100%[5/5 in infracardiac, 22%[2/9 in mixed type. The associated cardiac anomalies were persistent left SVC[2 , tricuspid valve regurgitation[3 , cor triatriatum[1 , and mitral cleft[1 . And associated noncardiac anomalies were imperforate anus[1 and Neil Weightman syndrome[1 . The operative mortality was 23%. The causes of death were pulmonary hypertensive crisis, perioperative myocardial failure, pneumonia with sepsis, arrhythmia and etc. The statistically significant factors in postoperative mortality were the pulmonary venous obstruction and age [p<0.01 . The operative mortality was high in groups of age under 1 month and pulmonary venous obstruction. The mean follow-up was 27.1 months. There were two late deaths. The first patient was three months old boy with supracardiac type and severe obstructive symptoms. The postoperative echocardiography was showed anastomotic stenosis and reoperations were performed twice but the patients expired due to pneumonia and sepsis. The second patient was three month old boy with supracardiac type and total correction was done and was doing well postoperatively. Eight years later, he expired suddenly due to arrhythmia. But all the other patients were in NYHA Fc I and received no medications. The 5-year survival rate excluding early expired patients is 97.1 $\pm$ 0.03 %. In conclusion, although the operative mortality of total anomalous pulmonary venous connection was relatively high compared to other major cardiac anomalies, we could expect excellent long-term results by early surgical correction.

  • Cardiovascular beriberi is caused by thiamine deficiency and usually presents as high cardiac output failure associated with predominantly right-sided heart failure and rapid recovery after treatment with thiamine. Because of its rarity in developed countries, the diagnosis can often be delayed and missed. We recently experienced a case of cardiovascular beriberi with pulmonary hypertension which successfully treated with thiamine infusion. A 50-year-old man with chronic heavy alcoholics was refered to our department for dyspnea with mental change. Echocardiography showed marked right ventricular (RV) dilatation and flattening of the interventricular septum with a D-shaped deformation of the left ventricle. Moderate tricuspid valve regurgitation was found and estimated RV systolic pressure was 52 mm Hg. Because of his confused mentality and history of chronic alcohol intake, neurological disorder due to thiamine deficiency was suspected and intravenous thiamine was administered and he continuously received a daily dose of 100 mg of thiamine. Follow up echocardiography showed marked reduction of RV dilatation and improvement of a D-shaped deformation of the left ventricle. He finally diagnosed as cardiovascular beriberi on the basis of dramatic response to intravenous thiamine. Thiamine deficiency can cause reversible pulmonary hypertension, and can still be encountered in the clinical setting. Thus high index of suspicion is critically needed for diagnosis.

  • From April 1977 to March 1991, 44 patients have undergone excision of intracardiac myx-omas, 36 cases were located in the left atrium[81.6%], 3 cases in the right atrium[6.6%], 2 cases in the right ventricle[4.5%], 3 cases in the left ventricle[6.6%], There were 32 female and 12 male. The mean age of patients was 39.6$\pm$12.3 years[ranged 11 to 67 years]. The major preoperative symptoms included exertional dyspnea in 35[79.6%], palpitation in 23[52.3%], syncopal episodes in 9[20.4%], and signs of systemic illness; low-grade fever, weight loss, arthralgia, headache and so on. The diagnosis was made by echocardiography alone in 7[15.9%], and by combination of angiography and echocardiography in 37[84.1%]. The weight of the tumor ranged from 15 to 115gm[mean weight, 47.6$\pm$27.6gm], and the volum of the tumor was 129.1cm3[$\pm$149.0]. Follow-up time ranged from 0.6 to 9 years[mean follow-up, 65$\pm$3.22 years]. There were no early and late deaths during the follow-up period. Tumor recurred in one patient with left atrial myxoma 8 years later, who underwent successful reoperation. Postoperative complications occurred in 12 patients: episodes of sup-raventricular arrhythmia in 7, convulsion in 2, wound problem in 2, tricuspid valve regurgitation in 1, massive bleeding in 1, and intubation granuloma in one. In conclusion, surgical excision of the myxoma can be considered curative with excellent long-term result.

  • A 25-month-old boy was referred to the hospital due to large head detected on routine physical examination. At visit, dysmorphic facial appearances, including broad nose, prominent forehead, and coarse face, were noted. Nasal obstruction with nasal voice, prominent adenoids, and bilateral middle ear effusions were detected. His abdomen was distended, and liver and spleen were palpated about 3 finger and 2 finger breadths, respectively. He was operated for bilateral inguinal hernias. The motion of both elbow joints was mildly limited on supination and pronation. Urinary level of glycosaminoglycan was elevated and the enzyme activity of iduronate sulfatase in leukocytes was decreased. The mutational analysis of the gene iduronate 2-sulfatase (IDS) revealed c.263G>A (p.Arg88His) mutation. His developmental scale showed delayed development and there was cardiac valvular involvement (tricuspid regurgitation and mitral valve prolapse). After the diagnosis of Hunter syndrome, enzyme replacement therapy started on a weekly basis without progression of any clinical features. Here we report a case of early diagnosed Hunter syndrome detected by large head on routine examination. Thus, it is important to associate Hunter syndrome in the patient with large head especially, if there is the history of bilateral inguinal hernia and prominent adenoids to increase the possibility of early diagnosis and treatment.

  • An anatomical understanding of the atrial myocardium is crucial for surgeons and interventionists who treat atrial arrhythmias. We reviewed the anatomy of the inter-nodal and intra-atrial conduction systems. The anterior inter-nodal route (#1) arises from the sinus node and runs through the ventral wall of the atrial chambers. The major branch of route #1 approaches the atrioventricular node from the anterior aspect. Other branches of route #1 are Bachmann's bundle and a vestibular branch around the tricuspid valve. The middle inter-nodal route (#2) begins with a broad span of fibers at the sinus venarum and extends to the superior limbus of the oval fossa. The major branch of route #2 joins with the branch of route #1 at the anterior part of the atrioventricular node. The posterior inter-nodal route (#3) is at the terminal crest and gives rise to many branches at the pectinate muscles of the right atrium and then approaches the posterior atrioventricular node after joining with the vestibular branch of route #1. The branches of the left part of Bachmann's bundle and the branches of the second inter-nodal route form a thin myocardial network at the posterior wall of the left atrium. These anatomical structures could be categorized into major routes and side branches. There are 9 or more anatomical circles in the atrial chambers that could be structural sites for macro re-entry. The implications of normal and abnormal structures of the myocardium for the pathogenesis and treatment of atrial arrhythmias are discussed.
