Atrial myxoma is a rare and benign clinical entity. It remains common in women and mainly affects the left atrium. Its clinical picture is polymorphic. We report the case of a 53-year-old woman who consulted for dyspnea with cardiac failure\'s picture. The diagnosis of myxoma of the left atrium was made on echocardiography which also objectified the existence of mitral stenosis. The patient underwent surgical excision and mitral valve replacement with good postoperative outcomes.

Shone syndrome is a rare and complex congenital heart disease. It is characterized in its complete form, by a constellation of the four potentially obstructive lesions of the left heart side. Incomplete Shone\'s complex includes 2 or 3 of the characteristic lesions which, include a supravalvular mitral membrane, valvular mitral stenosis (MS) by a parachute mitral valve (PMV), subaortic stenosis and aortic coarctation (Coa). We describe here, the case of a 35-year-old man, hospitalized for chronic dyspnea and in whom, the diagnosis of incomplete Shone\'s complex is retained by echocardiographic analysis. Observed lesions include a parachute mitral valve responsible for mild regurgitation and moderate mitral stenosis, bicuspid aortic valve, and pseudo interruption of the aorta with dilatation of the ascending aorta and a patent ductus arteriosus. This case is the 2nd on 3942 patients in Drighil congenital heart disease registry.

Mitraclip corrects mitral regurgitation in a less invasive way than cardiac surgery. These procedures are becoming widespread with the emergence of new complications. We report a rare case of mitral stenosis associated with acute hemolytic anemia after mitraclip treatment in an 82-year-old patient. The cause of this stenosis in our case is linked to the placement of two clips and an increase gradient in post-procedure. The mechanism of hemolysis could be due to the persistence of mitral leaks resulting in strong collisions against the clip.
