Tanto as pr\u00f3teses biol\u00f3gicas quanto as mec\u00e2nicas t\u00eam limita\u00e7\u00f5es para o sucesso da gravidez.  Objetivos  Estudar o \u00edndice de sucesso da gravidez ap\u00f3s o implante de pr\u00f3tese valvar, e identificar as vari\u00e1veis relacionadas aos desfechos maternos.  M\u00e9todos  Estudo prospectivo de 78 gestantes com pr\u00f3tese de peric\u00e1rdio bovino (Grupo PB) e 50 com pr\u00f3tese mec\u00e2nica (Grupo PM) quanto ao \u00edndice de sucesso da gravidez, considerado na aus\u00eancia de complica\u00e7\u00f5es card\u00edacas, obst\u00e9tricas e\/ou fetais.  Resultados  O sucesso foi alcan\u00e7ado em 64 (50,0%) pacientes, e n\u00e3o foi diferente entre os grupos (PB 56,4% vs. PM 40,0% - p=0,103). O grupo PB teve maior frequ\u00eancia de eventos card\u00edacos e de disfun\u00e7\u00e3o de pr\u00f3tese (43,6% vs. 16,0% p&lt;0,001; 26,9% vs. 2,0% p&lt;0,001), contudo perdas fetais (14,1% vs. 24,0% p=0,165) e complica\u00e7\u00f5es obst\u00e9tricas (28,2% vs. 42% p=0,127) n\u00e3o foram diferentes entre os grupos. A insufici\u00eancia card\u00edaca (odds ratio 8,5; CI 95% [1,4; 50,7]; p=0,019), fibrila\u00e7\u00e3o atrial (odds ratio 16,7; CI 95% [5,7; 49,1]; p&lt;0,001) e disfun\u00e7\u00e3o da pr\u00f3tese biol\u00f3gica (odds ratio 12,6; CI 95% [3,0; 52,7]; p=0,001) anteriores \u00e0 gesta\u00e7\u00e3o foram as vari\u00e1veis de predi\u00e7\u00e3o de insucesso da gravidez.  Conclus\u00f5es  Mulheres com pr\u00f3teses valvares tiveram baixo \u00eaxito materno-fetal decorrentes de fatores complicadores da doen\u00e7a valvar, da limitada sobrevida estrutural das pr\u00f3teses biol\u00f3gicas e da inexist\u00eancia de anticoagulantes que assegurem uma gesta\u00e7\u00e3o. A escolha da pr\u00f3tese valvar para a gravidez, n\u00e3o deve ser isolada, mas deve fazer parte de uma doen\u00e7a card\u00edaca de evolu\u00e7\u00e3o complexa.<\/jats:p>","DOI":"10.36660\/abc.20240163","type":"journal-article","created":{"date-parts":[[2025,3,26]],"date-time":"2025-03-26T12:25:09Z","timestamp":1742991909000},"source":"Crossref","is-referenced-by-count":1,"title":["A Escolha da Pr\u00f3tese Valvar para o Sucesso da Gravidez.
