Summary

이 프로토콜은 트랜스카테터 모성 판막 수리 중에 실시간 심초음파 지침을 수행하는 방법을 자세히 설명합니다. 기본 뷰와 필요한 측정은 절차의 각 단계에 대해 설명됩니다.

Abstract

대류 경피 성 경피 성 경피 성 지반 – 투 – 에지 재건은 높은 수술 위험이있는 환자에서 심한 증상 성모 역류에 대한 안전하고 잘 확립 된 치료법입니다. 불소 시경 검사 이외에 초음파 검사 지침은 금 본위제이며 표준화 된 기술을 사용하여 수행해야합니다.

이 문서는 보기, 측정뿐만 아니라 시술 중에 발생할 수있는 가능한 어려움을 강조하는 등 단계적 심초음파 가이드에 의해 재현 가능한 단계를 배치합니다.

이 문서에서는 절차의 각 단계에 대한 상세하고 연대순적인 심초음파 보기, 특히 2D와 3D 이미징 사이의 선호도를 제공합니다. 필요한 경우 펄스 웨이브, 연속 파 및 색상 도플러 측정이 설명됩니다. 또한 경피 적 가장자리 – 에지 수리 절차 중 승모 역류의 정량화에 대한 공식 권장 사항이 없기 때문에 승모 전단지를 파악한 후 및 장치 배포 후 심초음파 정량화에 대한 조언도 포함되어 있습니다. 또한, 이 기사는 절차 중 가능한 합병증을 예방하고 처리하기 위해 중요한 초음파 검사를 다룹니다.

트랜스카테터 모성 밸브 수리 중 초음파 검사가 필수적입니다. 구조화 된 접근 방식은 중재자와 이미저 간의 협력을 개선하고 안전하고 효과적인 절차에 필수적입니다.

Introduction

승모 역류(MR)는 유럽1에서판막 수술에 대한 두 번째로 빈번한 표시이다. 치료되지 않으면 심한 심부전과 삶의 질저하로이어질 수 있습니다2,3,4. 경피형 모성 판막 수리(PMVR)는 A2 및 P2 가리비5를연결하여 알피에리 스티치 수술 방법을 모방하여 승모 수리에 모방한 카테터 기반 기술이다. 높은 수술 위험이 있는 환자의 경우, 이 기술은 여러 레지스트리및 시험에서 가혹한 MR. 데이터의 치료를 위한 최소 침습적 접근법을 제공하며, 미트라클립 시술, 트랜스카테터 모성 판막 수리 요법은 효과적이고 안전한 방법6,7,8,9이다. 2019년에는 파스칼 트랜스카테터 밸브 수리 시스템이 시장에 도입되었습니다. 중증 MR10환자의 치료에 타당성 과 허용 가능한 안전을 보여 주었다. PMVR의 지속 시간과 성공은 개별 운영자의 기술과 경험11에따라 달라집니다. 형광법으로만 수행할 수 있는 경피성 경피성 발대치(TAVR)와 같은 다른 경피 기술과는 달리 PMVR은 심초음파지침(12,13)이필요하다.

이 문서에서는 측정, MR의 인트라프로치 수량화 제안 및 복막 합병증을 방지하기 위한 중요한 견해를 포함하여 PMVR 중 초음파 검사 접근법을 단계적으로 설명합니다.

Protocol

이 프로토콜은 우리 기관의 인간 연구 윤리 위원회의 지침을 따릅니다. 1. 개입 전 평가 경부 천자 전에 심근 절제를 제외합니다. 작은 심근 삼혈이 존재하는 경우, 오른쪽 심실(RV), 중간 식도 우심실 유출 뷰 및 긴 축(LAX) 뷰에 중점을 둔 4챔버(4Ch) 뷰에서 최대 단측 확장기 에코라이트 공간을 측정합니다. 좌측 상부 폐정맥(LUPV)에서 펄스파 도플러(PW)로 폐정맥 흐?…

Representative Results

경피 에지-에지 밸브 수리는 증상이 심한 MR으로 수술을 받을 자격이 없는 환자의 수술 용 판막 수리 또는 교체에 대한 대안입니다. MitraClip의 첫 번째 임상 응용 프로그램은 혈관 내 밸브 가장자리 – 투 – 에지 수리 연구 I (에베레스트 I)14 시험에서 조사되었다. 다른 많은 시험은 증상의 개선뿐만 아니라 병원 사망률및 부작용의 낮은 비율 (액세스 유럽 연합 (EU), TRAMI, 에베레스트 II…

Discussion

PMVR에 대한 에코 지침은 안전한 방법입니다. 에코카피오로 인한 합병증은 발생할 수 있지만 거의 심각한 손상으로 이어질 수 있습니다. 그럼에도 불구 하 고, 식도 병 변은 경도 에코 카르디그래피를 수행 한 후 가능. 이 부각은 내정간섭 의 짧은 기간으로 감소된다34. 반대로, 트랜스카테터 에지-투-에지 승모판 수리와 관련된 몇 가지 합병증이35,<sup class…
