Amyloidosis is a rare disease characterized by an extracellular accumulation of a protein polysaccharid complex (Amyloid). Cardiac involvement is considered as a major prognostic factor.We report the case of two women, hospitalized for heart failure. The diagnosis of cardiac amyloidosis was suggested by echocardiography: Left ventricular concentric hypertrophy and typical amyeloid infiltration with hyperechoic, shiny and granite-like aspect of the interventricular septum. The histological confirmation was obtained by gastric biopsy in the first case and biopsy of the salivary glands in the second revealing an amyloidosis AL. This cardiac amyloidosis was secondary to multiple myeloma: monoclonal Gammopathy with immunoglobulin Lambda in the first and Kappa in the second, and the presence of a plasmocyte infiltration in the sternal puncture.Amyloidosis is a rare pathology, the cardiac involvement is frequent in the type AL and can occur with or without clinical manifestations. Echocardiography should be systematic in patients with confirmed amyloidosis.

The goal of this study was to compare the clinical presentation and angiographic morphology of patients having an unstable angina pectoris. A total of 321 patients were consecutively studied and underwent cardiac catheterization, mean age 59 + 6 years. According to Braunwald classification, class III was predominant (58%) On coronary angiography, 148 patients had single vessel disease, double-vessel in 92 and triple-vessel in 64. Morphology of coronary artery lesions was classified according to Ambrose's classification, 100 patients had simple lesions (type I or IIA), 204 patients had complex lesions (type IIB, III, intracoronary thrombus or total occlusion). Thoracic rest pain (class III) or postinfarction angina (class C), were associated with the presence of complex lesions. This subgroup of high risk patients would benefit from either Glycoprotein IIb/IIIa blockers with an early revascularisation strategy.

Right heart emboli-in-transit have been echocardiographically documented in up to 4 to 23% of patient with acute pulmonary embolism. The most appropriate therapeutic approach still remains an unresolved problem because there are no prospective and randomized trials to definitively answer this question. Thrombolysis seems to be the more attractive alternative. We report a case of 44 years old man presented with a right atrial thrombus complicated by severe pulmonary embolism treated successfully by low molecular weight heparin.

Isolated congenital sick sinusal syndrome on non harmed heart is a rare affection. Its association with an atrio-ventricular block is exceptional. The authors report a case of a 19 year-old patient, with an early history of bradycardia, hospitalised for effort intolerance. His electrocardiogram reveals a high degree sino-atrial block replaced by a junctional rhythm at 30/mn. During Treadmill test, the sinusal acceleration is satisfactory and an effort atrio-ventricular block was present. He later had a definitive stimulation under DDDR. This report shows that the sinusal node, in the same way as the atrio-ventricular node may be injured by congenital dysimmunitary process. The coexistence of these two conductive troubles worsen the prognosis and should lead more often to the practice of definitive stimulation by the only mode DDDR.
