- Double orifice mitral valve in an asymptomatic adult with an unusual combination of congenital malformations: a case reportPublication . Proença, G; Freitas, A; Baptista, SB; Thomas, B; Fragata, J; Ferreira, RWe report a case of an asymptomatic adult patient, with several congenital malformations including an infrequent variant of double orifice mitral valve, postductal aortic coarctation, bicuspid aortic valve and an aneurysm of the right Valsalva sinus. The loss of support of the right coronary cusp of the aortic valve caused major aortic regurgitation. With the exception of the mitral valve, which was left untouched because it was neither stenotic nor regurgitant, all the other abnormalities were successfully corrected, in a two-step surgical approach.
- Hamartoma of the mitral valve with blood cysts: a rare tumor detected by echocardiographyPublication . Abreu, A; Galrinho, A; Sá, E; Ramos, S; Martins, A; Fragata, J; Ferreira, RA 16-year-old boy was submitted to a cardiac examination after an episode of faintness. A transthoracic echocardiogram was performed, which revealed a very mobile multicystic tumor attached to the mitral valve. A small solid mass adherent to the cysts was better defined by transesophageal echocardiography. The patient was submitted to cardiac surgery consisting of tumor resection and a mitral prosthesis implant. The surgery was successful. The tumor consisted of three bright red tense cysts with hematic content, each 1 to 2 cm in diameter. The cysts were coalescent and adherent to a solid mass attached to the posterior papillary muscle head. Histopathologic examination revealed a hamartoma with a cystic part composed of the proliferation of myofibroblast cells in a stroma with vessels, collagen, and elastin fibers. Valvular hamartoma with blood cysts is a very rare cardiac tumor both for its histopathology and its localization.
- Trombos intraventriculares com embolização sistémica: a propósito de dois casos clínicosPublication . Magno, P; Freitas, A; Cunha, P; Loureiro, J; Fragata, J; Ferreira, RA formação de trombos intraventriculares é um complicação frequente nos doentes com miocardiopatia dilatada e enfarte agudo do miocárdio, sendo o risco de embolização sistémica muito variável em função da patologia subjacente e características subjacentes dos trombos. Os autores descrevem dois casos clínicos relativos a dois doentes internados no mesmo dia com trombos intraventriculares, volumosos, protuberantes e muito móveis, no contexto de miocardiopatia dilatada e enfarte agudo do miocárdio, que embolizaram para os membros inferiores. Salientam a importância da ecocardiografia no diagnóstico, caracterização morfológica inicial e controlo evolutivo dos trombos intraventriculares, aspectos fundamentais na avaliação do risco embólico. Na ausência de recomendações específicas quanto às opções terapêuticas – anticoagulação, trombólise ou remoção cirúrgica, os autores sublinham a necessidade de avaliação individualizada, «caso a caso», tendo em conta o risco embólico, hemorrágico, e cirúrgico.
