A angina pectoris tamb\u00e9m pode ser uma manifesta\u00e7\u00e3o relevante, especialmente em casos nos quais ocorre compress\u00e3o extr\u00ednseca do tronco da art\u00e9ria coron\u00e1ria esquerda (TCE) pela art\u00e9ria pulmonar dilatada. Contudo, persistem lacunas significativas quanto \u00e0s estrat\u00e9gias diagn\u00f3sticas e terap\u00eauticas mais adequadas para a obstru\u00e7\u00e3o coronariana nesse contexto cl\u00ednico.  Objetivos  Avaliar a viabilidade e o impacto da angioplastia coronariana com stent no al\u00edvio dos sintomas em pacientes com HP associada \u00e0 compress\u00e3o extr\u00ednseca do TCE.  M\u00e9todos  Trata-se de um estudo descritivo que incluiu 12 pacientes com HP acompanhados no Ambulat\u00f3rio de Circula\u00e7\u00e3o Pulmonar do Instituto do Cora\u00e7\u00e3o do Hospital das Cl\u00ednicas da Faculdade de Medicina da Universidade de S\u00e3o Paulo. Todos foram submetidos a angioplastia coronariana com implante de stent visando ao tratamento da compress\u00e3o extr\u00ednseca do TCE.  Resultados  Foram analisados 12 pacientes, com idade m\u00e9dia de 47,9 anos, predominantemente com HP do grupo 1 e em uso de terapia espec\u00edfica. Todos apresentaram excelente resultado imediato da angioplastia, com al\u00edvio da angina ap\u00f3s 30 dias. Durante o seguimento m\u00e9dio de 33 meses, n\u00e3o foram observadas complica\u00e7\u00f5es relacionadas ao procedimento, mantendo-se o controle dos sintomas anginosos. Quatro pacientes evolu\u00edram a \u00f3bito em decorr\u00eancia da progress\u00e3o da insufici\u00eancia card\u00edaca.  Conclus\u00e3o  Os resultados observados refor\u00e7am a viabilidade da angioplastia coronariana como estrat\u00e9gia para o al\u00edvio sintom\u00e1tico da angina em pacientes com compress\u00e3o do TCE e HP. Estudos adicionais s\u00e3o necess\u00e1rios para avaliar o impacto dessa interven\u00e7\u00e3o em desfechos cl\u00ednicos robustos, bem como a relev\u00e2ncia do rastreamento em pacientes assintom\u00e1ticos.<\/jats:p>","DOI":"10.36660\/abc.20250002","type":"journal-article","created":{"date-parts":[[2025,8,1]],"date-time":"2025-08-01T19:24:37Z","timestamp":1754076277000},"source":"Crossref","is-referenced-by-count":2,"title":["Angioplastia
