Basal Interventricular Septal Aneurysm in Rheumatic Mitral Stenosis
نویسندگان
چکیده
even in that cases, the basal portion of the muscular IVS is spared. Our patient had a well defined aneurysm of the basal IVS which was contractile in nature. The mechanism behind the development of aneurysm in our case might be the eccentric jet of mitral stenosis constantly striking the basal IVS region. Aneurysmal deformity of the basal IVS secondary to impinging turbulent transprosthetic eccentric flow jet has also been previously reported. The aneurysmal deformity in our case may be congenital or idiopathic, but the previous echocardiographic records did not metion such a deformity. In summary, this is a rare case of a basal IVS aneurysm coexisting with and likely to be caused by eccentric jet of rheumatic mitral valve stenosis.

Echocardiographic mitral systolic motion in left ventricular aneurysm.
An abnormal, convex systolic anterior motion of the mitral valve, somewhat similar to that seen in idiopathic hypertrophic subaortic stenosis (hypertrophic obstructive cardiomyopathy) and occasionally in atrial septal defect, was found on the echocardiogram in 8 out of 9 patients with angiographically (7 patients) and/or clinically (2 patients) diagnosed left ventricular aneurysm secondary to m...
متن کاملAortic root dissection. Another cause of early systolic closure of the aortic valve.
An early systolic closure of the aortic valve was recorded in the echocardiogram in two patients with aortic root dissection. This sign, initially described in discrete subaortic stenosis and occasionally observed in mitral regurgitation and interventricular septal defect, has not so far been described in dissecting aneurysm of the aorta.
متن کاملLeft ventricular function in rheumatic mitral stenosis.
Haemodynamic factors contributing to clinical disability in patients with rheumatic mitral stenosis have been under discussion and investigation for decades. Prior to the development of left heart catheterization, a low cardiac output in the presence of little or no pulmonary hypertension was taken as evidence for a myocardial 'insufficiency'. With the use of left heart catheterization, it was ...
متن کاملMembranous subaortic stenosis complicated by aneurysm of the membranous septum and mitral valve prolapse.
The clinical, echocardiographic, and catheterization findings in a patient with discrete subaortic stenosis, aneurysm of the membranous interventricular septum, and mitral valve prolapse are presented. Echocardiography showed a subaortic membrane, abnormal aortic valve motion, accentuated systolic anterior motion of the membranous interventricular septum, and prolapsing mitral leaflets. Cardiac...
متن کاملContinuous murmur due to the combination of rheumatic mitral stenosis and a rare type of anomalous pulmonary venous drainage.
SUMMARY A patient is described in whom a continuous murmur was caused by the combination of rheumatic mitral stenosis and a rare form of partial anomalous pulmonary venous drainage. In this case, the left superior pulmonary vein drained into the left atrium and also into a large anomalous vein which then drained to the right atrium via the innominate vein and superior vena cava. At surgery, mit...
