Incidental Asymptomatic Giant Hydatid Cyst of the Interventricular Septum Bulging Into the Right Ventricle

Hydatid disease is caused by the larvae of Echinococcus granulosus. Domestic animals like cats and dogs are the primary carriers of echinococcal organisms. This parasitosis is still endemic in some particular regions of the world. The cardiac hydatid cyst is an exceptional infection. We report a case of an asymptomatic giant cardiac hydatid cyst in the interventricular septum (IVS) protruding in the right ventricular diagnosed incidentally by scan tomography during acute pancreatitis emergency. Transthoracic echocardiography revealed a cystic mass in the IVS bulging into the right ventricle. The diagnosis was confirmed by a cardiac CT scan.

Reversible severe mitral regurgitation caused by systolic anterior motion of the mitral valve in the absence of left ventricular hypertrophy: A case report

A 67-year-old woman with exertional dyspnea was referred to our hospital. Transthoracic echocardiography revealed severe mitral regurgitation and significant left ventricular (LV) outflow tract obstruction due to prominent systolic anterior motion (SAM) of the mitral valve without LV hypertrophy. Oral bisoprolol remarkably attenuated SAM. Two- or three-dimensional echocardiographic analysis demonstrated the elongation of anterior and posterior mitral leaflets and interventricular septum (IVS) bulging due to narrow aorto-mitral angle. In the present case, elongation of mitral leaflet and hyperkinetic motion of left ventricle, and IVS bulging due to narrow aorto-mitral angle possibly play important roles in the development of SAM.<Learning objective: Mitral regurgitation due to systolic anterior motion (SAM) can be dramatically improved by beta-blocker therapy. Although the precise mechanism of SAM has not been fully elucidated, structural changes of mitral apparatus (elongation of mitral leaflet and papillary muscle displacement), and structural or functional features of left ventricle (hyperkinetic motion, small ventricle, interventricular septum bulging, narrow aorto-mitral angle) possibly play important roles in the development of SAM.>

Left ventricular apical hypoplasia: An unusual diagnosis

A 36-year-old woman was referred for medical evaluation prior to non-cardiac surgery. She was healthy and only complained of sporadic palpitations. The 12-lead electrocardiogram showed sinus rhythm and left bundle branch block. Transthoracic echocardiography revealed a normally functioning, slightly dilated left ventricle (LV), with the interventricular septum bulging toward the right ventricle (RV), which was elongated and wrapped around the LV (Figure 1; Supplementary material Videos S1 and S2). The papillary muscles were structurally abnormal and presented
