Prolapse of the aortic valve is the main cause of insufficiency of the aortic valve as a complication of ventricular septal defect. Aortic insufficiency gets worse by the progress of prolapse of aortic valve due to lack of support of the valve and the hemodynamic effect of blood flow through the ventricular septal defect. This produces typical clinical picture, that may be serious and threatening when it is untreated. Type and timing for the surgical treatment of the ventricular septal defect with aortic insufficiency is considered. Among 113 ventricular septal defect, 9 patients of ventricular septal defect with associated aortic insufficiency were experienced from June. 1983 to June 1988 at the Department of Thoracic and Cardiovascular Surgery, Chon-Buk University Hospital. Male was 6 patients and female was 3 patients. Ages were from 7 years to 24years. 5 patients were from 10 to 19 years age. 3 patients were below 10 years age. The ratio of pulmonary blood flow to systemic f low [Qp/Qs] was 1.53 and in pulmonary vascular resistance, normal or slight increase was 7 patients, moderate 1 patient, and severe 1 patient. Ventricular septal defect was subpulmonic in 5 patients and infracristal in 4 patients. Prolapse of right coronary cusp was 7 patients, right and non coronary cusp 1 patient and non coronary cusp 1 patient. Teflon patch closure of ventricular septal defect was undertaken in 3 patients and primary closure in 1 patient. Among the 4 patients of defect closure alone, one patient performed valve replacement 7 months later due to progressive regurgitation and cardiac failure and the result was good. The other 3 patients were good result. Closure of ventricular septal defect and aortic valvuloplasty performed in 4 patients. 2 patients of these required valve replacement for the sudden intractable cardiac failure and died due to low cardiac output. The cause of intractable cardiac failure was tearing of repaired valve at the fixed site. The other 2 patients were good result. Closure of ventricular septal defect and valve replacement performed in 1 patient with good result.

Background: Minimally invasive cardiac surgery has emerged as an alternative to conventional open surgery. This report reviews our experience with atrial septal defect using the da VinciTM surgical robot system. Materials and Methods: This retrospective study included 50 consecutive patients who underwent atrial septal defect repair using the da VinciTM surgical robot system between October 2007 and May 2011. Among these, 13 patients (26%) were approached through a totally endoscopic approach and the others by mini-thoracotomy. Nineteen patients had concomitant procedures including tricuspid annuloplasty (n=10), mitral valvuloplasty (n=9), and maze procedure (n=4). The mean follow-up duration was $16.9{\pm}10.4$ months. Results: No remnant interatrial shunt was detected by intraoperative or postoperative echocardiography. The atrial septal defects were mainly repaired by Gore-Tex patch closure (80%). There was no operative mortality or serious surgical complications. The aortic cross clamping time and cardiopulmonary bypass time were $74.1{\pm}32.2$ and $157.6{\pm}49.7$ minutes, respectively. The postoperative hospital stay was $5.5{\pm}3.3$ days. Conclusion: The atrial septal defect repair with concomitant procedures like mitral valve repair or tricuspid valve repair using the da VinciTM system is a feasible method. In addition, in selected patients, complete port access can be helpful for better cosmetic results and less musculoskeletal injury.

A 9-month-old, 11.3 kg, intact, male, mixed-breed dog was referred for treatment of cor triatriatum dexter (CTD); a 5-month-old, 1.9 kg, intact, male Maltese for pulmonic stenosis (PS); and a 3-year-old, 6.62 kg, intact, female West Highland white terrier for esophageal stricture with regurgitation. A balloon catheter intervention was performed in the dog with CTD, and subsequent color Doppler ultrasound and abdominal ultrasound showed normal blood flow across the perforated membrane dividing the right atrium and the disappearance of the severe ascites present before treatment. Balloon catheter intervention in the dog with PS reduced the blood flow through the stenosis from 5.82 m/s to 3.97 m/s. In the dog with esophageal stricture, balloon catheter intervention widened the esophagus and no subsequent regurgitation was observed. Balloon catheter intervention is an interventional radiology procedure that represents a definitive treatment option for various stenotic lesions in dogs, including CTD, PS, and esophageal stricture. Although interventional radiology procedures for these diseases have already been reported, details of procedures and successful outcome have not been reported in Korea.

The management of cardiac arrhythmias by cardiac pacing has increased greatly since the treatment of complete heart block with an external transcutaneous pacemaker in 1952, followed by the use of myocardial wires connected to an external pulse generation, by external transvenous pacing, and then by transvenous pacing with implantable components in thoracic wall.By now, the three bases of modern cardiac pacing for bradyarrhythmias had been established [1] an implantable device [2] the transvenous approach [3] the ability of the pacemaker to sense cardiac activity and modify its own function accordingly. In transvenous implantation of a pacemaker, any one of four vessels at the root of the neck is suitable for passage of the electrode - cephalic vein, external jugular vein, internal jugular vein, costo-axillary branch of the axillary vein. The new technique of direct puncture of the subclavian vein, either percutaneously or after skin incision only has been made, is invaluable & is used routinely. We have experienced one 25 years old patient who had rheumatic mitral stenosis & minimum aortic regurgitation with sinus bradycardia associated with premature atrial tachycardia & another 54 years old female patient who was suffered from sick sinus syndrome with sinus bradycardia & sinus arrest. The 1st patient was taken open mitral commissurotomy & aortic valvuloplasty and then was taken atrlal pace-maker implantation through If subclavian puncture method in post-op 14 days, and the second patient was taken atrial pacemaker implantation through If subclavian puncture method. Their postop course was in uneventful & were discharged, without complication. Their condition have been good to now.

배경: 소아 환자의 승모판막 질환에 대한 외과적 치료는 그 모양의 다양성과 동반된 선천성 심장 기형 등으로 인해 기술적, 임상적으로 어렵다. 본 연구는 선천성 승모판막 폐쇄부전증 환아에서 본원에서 시행한 승모판막 성형 수술의 결과를 평가하였다. 대상 및 방법: 1997년 4월부터 2007년 10월까지 승모판막 폐쇄부전증으로 승모판막 수술을 시행한 소아 환자 22명을 대상으로 후향적으로 분석하였다. 수술 당시 환아의 평균 연령은 5.4세였고, 이 중 12개월 미만의 영아는 4명이었다. 동반된 심기형으로는 심실 중격결손이 13예로 가장 많았고, 그 외에 심방 중격결손과 판막 상부 대동맥 판막 협착증(supravalvar aortic valve stenosis)이 각각 1예 있었으며, 승모판막 페쇄부전증만 단독으로 있는 경우는 7예가 있었다. 수술 전 승모판막 페쇄부전증의 정도는 II, III, IV가 각각 4예, 15예, 3예였고, 그 원인으로 판막 탈출증(leaflet prolapse)이 12예, 판막륜 확장(annular dilatation)이 4예, 제한된 판막 움직임(restrictive leaflet motion)이 5예 있었다. 수술 전후의 페쇄부전증 정도와 승모판막륜의 Z-value를 비교함으로써 그 결과를 평가하였다. 결과: 모든 환자에서 판막 성형술이 가능했고, 수술 후 조기 사망과 만기 사망 모두 얼었다. 19예에서 판막륜 축소술(reduction annuloplasty)을 시행하였고, 18예에서 건삭 축소술(shortening of chordae)이나 판막열 봉합술(cleft closure) 등의 판막 성형술(valvuloplasty)은 추가로 시행하였다. 수술 직후 승모판막 폐쇄부전증의 정도는 줄어들었고(0=10, I=5, II=5, III=2), 승모판막륜의 Z-value도 감소하였다($2.2{\pm}2.1$ vs $0.7{\pm}2.3$, p<0.01). 3.68년의 추적기간 동안 3명의 환아가 승모판막 폐쇄부전증으로 재수술을 받았고, 한명은 재성형술을, 나머지 2명은 승모판막 치환술을 받았으며, 퇴원 시 3명의 환아에서 수술 직 후 보다 폐쇄부전증이 좀 더 진행되었다. 결론: 소아의 승모판막 페쇄부전증에서 일차 수술방법으로 적극적인 승모판막 성형술은 효과적이고 믿을만한 방법이다. 좀 더 좋은 수술 결과를 얻기 위해서는 수술 전 환아의 승모판막의 모양과 기능을 면밀히 파악하고, 다양한 수술적 기법을 적용하는 노력이 필요하겠다.
