title: Carcinoid heart disease: two cases of left heart involvement diagnosed by transthoracic and transoesophageal echocardiography.
abstract: We report two observations of significant left heart involvement in patients with the carcinoid syndrome assessed by transthoracic and transoesophageal echocardiography. Echocardiographic lesions of this kind have only been reported twice. In the present cases, there was mitral involvement with mitral regurgitation in one case and a mitro-aortic involvement with mitral and aortic regurgitation in the other. The mechanism of left heart lesions is unclear since in both cases no right-to-left cardiac shunt was present, as attested by colour Doppler and saline contrast transoesophageal echocardiography. The location of the primary tumour was unknown in one case and ileal in the other; no pulmonary metastasis was detected. The use of transoesophageal echocardiography might make it possible to detect left-sided cardiac lesions more frequently since they were found in anatomical series, in 30% of patients with carcinoid syndrome.
