신생아에서 선천적 삼첨판 폐쇄부전은 자주 보고되지만 건삭파열에 의한 이차성 삼첨판 폐쇄부전은 아주 드물다. 환아는 생후 1일의 남아로 출생 직후부터 심한 호흡곤란, 청색증 및 산혈증이 관찰되었고, 무호흡과 함께 서맥이 빈번히 나타났다. 심초음파도 검사를 시행하여 폐동맥 판막을 통한 우심유출로 혈류가 관찰되지 않아서 폐동맥 폐쇄증으로 진단되었다. 수술 소견에서 폐동맥 및 폐동맥 판막의 기형은 전혀 없었고, 삼첨판의 전방 유두근 건삭파열이 새로이 확인되었다. 삼첨판 폐쇄부전은 건삭 형성술을 실시하여 성공적으로 교정하였으며, 술전 심초음파도에서 주폐 동맥에 폐혈류가 관찰되지 않았던 것은 심한 삼첨판 폐쇄부전 때문이었던 것으로 판단되었다.

Untreated severe tricuspid regurgitation (TR) is associated with poor outcomes. Functional TR occurs secondary to dilatation of the annulus and tethering of the leaflets. Ring annuloplasty alone can correct most cases, but is insufficient in cases of severe annular dilatation due to severe leaflet tethering. In such cases, a tricuspid edge-to-edge technique may be an option. However, stitching of the leaflet tips alone is likely to result in tearing of the leaflets. Approximation of the durable chordae tendineae is considered helpful for this problem. Herein, we present the case of a 39-year-old man who had undergone open-heart surgery for acute type A aortic dissection 13 months earlier. A right mini-thoracotomy approach with a beating-heart strategy was used, which did not require unnecessary pericardial adhesiolysis and dissection. This technique had the advantage of reducing the operation time and the risk of bleeding. To summarize, we present a case of tricuspid valve repair in a high-risk patient with severe leaflet tethering that was successfully managed using these methods.

Background: We evaluated the early clinical outcomes of tricuspid valve annuloplasty (TAP) with the Tri-Ad annuloplasty ring for functional tricuspid regurgitation (TR). Methods: From January 2015 to March 2017, 36 patients underwent TAP with a Tri-Ad ring for functional TR. To evaluate the early clinical outcomes of TAP with the Tri-Ad ring, we conducted a propensity score-matched analysis comparing the Tri-Ad and $MC^3$ tricuspid annuloplasty rings (n=34 in each group). The follow-up duration was $11.0{\pm}7.07$ months. Results: There was 1 case of operative mortality (2.8%) and no cases of late mortality. Postoperative complications occurred in 15 patients (41%), including acute kidney injury in 6 patients (16%), bleeding requiring reoperation in 4 patients (11%), and low cardiac output syndrome in 4 patients (11%). There were no ring-related complications, such as atrioventricular block or ring dehiscence. The TR grade decreased significantly (from $2.03{\pm}1.06$ to $1.18{\pm}0.92$, p<0.01), as did the systolic pulmonary artery pressure (from $43.53{\pm}13.84$ to $38.00{\pm}9.72mm\;Hg$, p=0.03). There were no cases of severe residual TR, but moderate TR was observed in 3 patients, all of whom had severe TR preoperatively. Severe preoperative TR was also associated with moderate in the univariate analysis (p<0.01). In the propensity score-matched analysis comparing the Tri-Ad and $MC^3$ rings, there was no significant difference in early clinical outcomes. Conclusion: TAP with the Tri-Ad ring corrected functional TR effectively and provided good early clinical and echocardiographic results without ring-related complications. However, severe preoperative TR was associated with moderate or severe residual TR in the immediate postoperative period. A follow-up study is necessary to confirm the stability of this procedure.

Since 1968 up to the end of October 1980, 448 valves were replaced in 354 patients in Seoul National University Hospital. There were 238 mitral, 38 aortic, 7 tricuspid, 45 aortic with mitral, 23 tricuspid with mitral, and 3 triple valve replacement aortic mitral and tricuspid cases. Annual increase of mitral valve replacement cases and decrease of operative maortality were remarkable. Recently operative mortality of mitral valve replacement is about 5%. Sex ratio of mitral valve replacement is almost equal and there were 12 cases of pediatric patients (5%) among 238 cases, and patients under the age of 20 years were 34 (14.3%). Mitral valve replacement was done for 199 single mitral, 38 double valve and one triple valve lesions. Among 238 mitral valve replacement paients left atrial thrombus in 23(9.7%), atrial fibrillation in 132 (55.5%), and reoperation after blind mitral commissurotomy in 12(5%) cases were noted. In recent cases bioprosthetic valves, mainly lonescu-shiley valve were utilized to overcome the difficulties of postoperative late complications in anticoagnuation, especially for the rural patients and pediatric cases, in addition to the hemodynamic advantages of lonesocu valve. Among 354 patients 16 cases were congenital heart anomaly related, 5 ventricular septal defect related aortic and 4 Ebstein related tribuspid valve replacement cases. There were 2 congenital anomaly related mitral valve replacements, one for congenital mitral insufficiency of 7 years old boy and one for corrected transposition of the great vessels associated with mitral insufficiency. Among total 354 valve replacements 49 operative deaths (13.3%) were noted and in 238 mitral valve replacement 24 operative deaths occurred (10.1%). In 39 patients among 354 total valve replacements late complications were found. In 238 mitral valve replacement cases late complications were noted in 26 patients, among whom 16 cases expired. Main late complications were thrombe-embolism, subacute becteerial endocarditis, arrythmia cerebral hemorrhage due to unsatisfactory anticoagulation, and congestive heart failure in the incipient period of valve replacement were also noted. In mitral valve replacement cases long-term survival rate was 83.2% who showed marked clinical improvement. Ther were no evidences of calcification during the 2 years follow-up period for the lonescu-valve replacement cases among 19 pediatric patients. In conclusion 238 cases of mitral valve replacement were done with 24 operative deaths and 26 late complication cases among whom 16 expired. The long term survival was 83.2% of the cases. In pediatric cases in place of coumadin anticoagulation Persantin **** 75 and aspirin were administered after valve replacement. In adult cases who have difficulaties with coumadin anticoagulation and for those even with bioprosthetic heart valve replacement who needs long-term or permanent anticoagulation persantin 75 and aspirin combination regimen were administered with antisfactory results.

Increased clinical interest, stimulated by newer diagnostic techniques, has made it apparent that Ebstein`s anomaly represents a spectrum of right heart abnormalities. In the usual case, the septal and posterior leaflets of the tricuspid valve are not attached to the true annulus, but are displaced distally into the ventricle. Also the degree of malattachment and the structural deformities of the cusps may vary greatly. Recently we experienced 6 cases of Ebstein`s anomaly who underwent corrective operation in our hospital. Five patients were operated by plication and annuloplasty techniques based on the construction of a monocusp valve by the use of the anterior leaflet. Remained one was operated on by tricuspid valve replacement using No 31 mm C-E tissue valve. There was no operative mortality and the postoperative courses were relatively good with marked symptom improvement.

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.
