RESUMO
Right ventricle organized thrombus is a rare pathological condition diagnosed in patients with a risk factor. The most common are right ventricle (RV) failure, autoimmune disease (Behcet disease), hypercoagulable disorder, anaemia, RV pacing leads, pulmonary artery catheters, RV infarction, and ventricular arrhythmogenic cardiomyopathy. The literature describes the impact of iron-deficiency anaemia on thrombosis. We described surgical extirpation of the organized right ventricle outflow tract (RVOT) thrombus in a patient with iron-deficiency anaemia.

RESUMO
INTRODUCTION: According to Carpentier classification, group III of mitral insufficiency is caused by the restrictive motion of the mitral valve. A rheumatic process and a coronary disease are the main causes. It is very important to examine the valve precisely, to define deformities and aetiology in order to make such a valve functional. In rheumatic disease, fibrosis and degeneration deform the entire mitral apparatus. A surgical principle is to re-establish mobility and pliability of the apparatus taking care of the functional anatomy at the same time. Cusp enlargement, chordal mobilization and ring remodelling arejust some of the numerous surgical techniques that could be performed in these patients. CASE OUTLINE: A 55-year-old female patient was admitted to hospital with severe mitral regurgitation. She belonged to NYHA, functional stage 2. Echocardiography revealed that both cusps, mostly posterior, were of reduced size and mobility, resulting in grade 3 regurgitation. We performed posterior cusp enlargement by using autologous pericardium treated in 0.6% of glutaraldehyde solution. Annulus remodelling was done using size 27 flexible Duran ring. Control echocardiography found trivial regurgitation. The patient was discharged on 12th postoperative day in sinus rhythm. CONCLUSION: Surgical reconstruction of the rheumatic mitral valve back to the functional state is a demanding procedure, which, however, provides certain benefit for the successfully treated patient.
