[Primary cardiac lymphoma. Report of a case].

Malignant non-Hodgkins lymphomas have a secondary cardiac localisation in 20% of cases. However, a cardiac primary site is rare (44 cases described up to now). A positive diagnosis is rarely made before death. There is great interest in echocardiography, a non-invasive method, to identify these tumours early. The prognosis remains nevertheless gloomy. We report the case of a child aged 8 years, admitted with a scenario of low output right cardiac insufficiency. Chest radiography identified cardiomegaly with a prominent right border, and the electrocardiograph showed right auricular hypertrophy. A tumour mass infiltrating the right atrium, the right ventricle and the lateral face of the left ventricle was discovered on trans-thoracic echocardiography. Investigation for tumour spread was negative. The patient died before operation in a state of extreme low output. The histology favoured a highly malignant non-Hodgkins lymphoma type B.

[Ruptures of the posterior wall of the left ventricle after mitral valve replacement: surgical repair and prevention].

We report two cases of type III rupture of the left ventricle posterior wall, situated midway between the mitral annulus and the posterior papillary muscle and occurring in immediate continuations of a mitral valvular replacement. The first case has occurred at the moment of the canulas removal in a 28 years old patient operated for mitral stenosis. The tear was repaired with horizontal mattress sutures through felt strips on the external surface of the heart. The immediate post operative course was marked by bleeding recurrence and cardiac failure which has led to death. In the second case, a 68 years old man was operated for degenerative mitral insufficiency. The rupture has occurred just before closing the chest. The repair was realized successfully by using an intra-ventricular patch. The chordae tendinae removal constitutes a factor predisposing to the left ventricle posterior wall rupture. The repair has to use an intra-ventricular patch. The prevention is based on the preservation of the continuity between the mitral annulus and papillary muscles by preserving the sub-valvular apparatus or by using synthetic chordae.

[Right atrial hemangioma presenting as pericardial tamponade. A case report].

Intracardiac haemangioma is a very rare benign primary cardiac tumour. A 40-year-old patient, with no notable history, presented with chest pain, accentuated by deep inspiration, associated with NYHA stage III dyspnoea. Physical examination revealed signs of right heart failure and electrocardiogram showed low voltage with diffuse repolarization disorders. Chez x-ray showed a cardiothoracic index CTI > 0.70, and enlarged right margins. A large pericardial effusion with a tumour mass filling the right atrial cavity was discovered on transthoracic echocardiography. Chest computed tomography demonstrated the tissue origin of the tumour and suggested extension to the inferior vena cava and hepatic veins. The patient was referred to a surgeon for tumour resection. Histological examination revealed intracardiac capillary haemangioma. Five month postoperative follow-up did not reveal any abnormalities.

[Double recurrence of myxoma of the left atrium. Apropos of a case].

Multiple recurrences of cardiac myxomas are rare and high-light the problem of re-operation. We report a case of double recurrence of left atrial myxoma and analyse the causes of recurrence. In our case, the first myxoma was inserted in the left inter-atrial septum, and the first recurrent tumor was inserted near the pulmonary vein, forming adhesion with the inter-atrial septum. The second recurrent tumor was inserted in the inter-atrial septum. The first operation resected the tumor, including part of the inter-atrial septum, and the sides of the septum were sutured. The two following operations used a patch for the septoplasty. This case is sporadic and not included in the high risk myxoma recurrence syndrome. Incomplete tumor resection is incriminated in one third of recurrences but seems unlikely in our case.
