Background: Analyses of the efficacy and safety of transcatheter aortic valve replacement (TAVR) in most countries have been based on outcomes obtained in accordance with national practice guidelines and monitoring protocols. The purpose of this study is to share our experience regarding the process for establishing guidelines and monitoring protocols for the use of TAVR in Korea, in the hopes that it may be helpful to others undergoing a similar process in their own country. Methods: The Korean guidelines for TAVR were established on June 1, 2015 in through a tri-party agreement involving the Department of Health and Welfare, the Korean Society of Thoracic and Cardiovascular Surgery and the Korean Society of Cardiology. We agreed to monitor the guidelines transparently and to exchange opinions regarding amendments or continuation of its contents after 3 years of monitoring. Results: The monitoring meetings were not held as regularly as agreed, and monitoring was also made difficult by insufficient and incomplete data. Nevertheless, during the meetings, measures to improve the monitoring process were discussed, and accordingly, an agreement was made to continue the monitoring process, with the aim of completing data collection by 2018. Conclusion: Compliance with guidelines is critical for assessing the efficacy and safety of TAVR. Moreover, the TAVR monitoring process must be properly conducted for an accurate evaluation to be made. Any country planning to introduce TAVR may encounter difficulties with regards to the optimal initiation strategy and subsequent monitoring. Nevertheless, continued efforts should be made to persuade the government and the corresponding medical societies to facilitate the optimal application of TAVR.

Shone complex is a rare congenital disorder that involves 4 obstructive lesions of the left heart, as follows: parachute mitral valve, supravalvular mitral ring, subaortic stenosis, and coarctation of the aorta. Incomplete forms with 2 or 3 of these lesions in adult patients have been rarely reported in the literature, meaning that insufficient general data exist concerning the surgical strategy and clinical follow-up. Herein, we report the case of a 31-year-old woman with a diagnosis of incomplete form of Shone complex with parachute mitral valve and coarctation of the aorta who underwent successful single-stage surgical repair.

배경: 선천성 이엽성 대동맥판막질환에 대한 성형술은 술 후 조기 성적에서는 매우 우수하다고 알려져 있으나 중기 및 장기 성적에 대해서는 논란이 되고 있는 실정이다. 대상 및 방법: 판막 성형술의 중기 성적을 알아보기 위해 1994년부터 2003년까지 선천성 이엽성 대동맥판막질환으로 판막성형술을 시행받은 22명의 환자들의 임상기록 및 심초음파 검사들을 후향적으로 분석하였다. 결과: 남자가 17명, 여자가 5명이었으며 평균 연령은 41$\pm$14세였다. 이엽성 판막의 폐쇄부전이 대부분(91%=20/22)의 환자에서 주 병변이었다. 수술 방법들로는 붙어 있는 공통 판막엽의 해리(release)가 19예(86%)에서 시행되었으며, 이탈된 판막엽에 대한 수술로는 채기 절제 및 일차봉합술이 11예(50%), 판엽줄임술(plication) 후 심막으로 보강한 것이 6예(27%), 판막엽만 줄인 3예(14%)가 있었다. 두꺼워진 판막엽을 깎은 것이(slicing) 12예(55%)에서 사용되었으며, 교련부위의 성형술은 8예(36%), 교련부위절개술이 6예(27%)에서 시행되어 평균 환자당 2.8개의 술식이 사용되었다. 수술 사망은 없었으며 모든 환자를 술 후 평균 38$\pm$17개월간 추적 관찰하였다. 추적기간 중 1명의 환자가 술 후 2개월에 성형술 봉합의 풀림에 의한 급성 대동맥판막 폐쇄부전으로 대동맥 판막 치환술을 받았다. 환자들의 기능적 상태는 (NYHA functional class)는 술 전 평균 1.9$\pm$0.6에서 술 후 1.2$\pm$0.5로 의미있게 개선되었으며(p<0.01), 심초음파 검사상 좌심실의 수축기말/이완기말 용적도 각각 45$\pm$9 mm, 67$\pm$10 mm에서 37$\pm$10 mm, 56$\pm$10 mm로 의미있게 줄어들었다(p<0.05). 대동맥 판막의 폐쇄부전 정도는 술 전 3.1$\pm$1.2에서 심폐기 이탈 직후에 0.9$\pm$0.7로 의미있게 줄었으나 추적 관찰 중 1.8$\pm$1.1로 증가하는 양상을 보였다. 중등도 이상의 폐쇄부전이 없이 생존할 확률은 술 후 1년에 89.7%, 3년에 89.7%, 4년에 39.9%로 나타나 중기 이후에 판막기능의 악화가 빨라지는 경향을 보였다. 결론: 선천성 이엽성 대동맥판막질환 성형술의 중기 성적은 임상적으로는 초기의 우수한 상태를 유지하였으나, 성형된 대동맥 판막의 장기적 내구성은 장담할 수 없었다.

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.
