Apical hypertrophic cardiomyopathy (HCM) is an uncommon variant of HCM characterized by apical hypertrophy without the septal predominance seen in the majority of HCM cases. In 2% of patients, a concomitant left ventricular apical aneurysm is observed, which increases the risk of sudden death and adverse HCM‐related events. Multimodality imaging is helpful for appropriate identification of this particular morphologic pattern. Herein, we present a case of apical HCM with a left ventricular apical aneurysm, exemplifying the utility of a multimodality approach from resting electrocardiogram, transthoracic echocardiogram, left ventriculography, and cardiac magnetic resonance imaging, for proper risk stratification and treatment planning. 相似文献

Hypertrichosis is a condition in which hair is longer and denser than what is considered normal for an individual based on age, sex, ethnicity, and location on the body and can be classified based on its distribution (generalized vs localized), age of onset (congenital vs acquired), and type of hair (lanugo or vellus vs terminal). We describe a rare case of monozygotic female twins who presented for localized hypertrichosis of the intermammary cleft that developed during puberty. Endocrine examination was unremarkable. Discussion of various treatment modalities should be considered, because localized hypertrichosis may have a considerable psychosocial effect. 相似文献

Prosthetic valve infective endocarditis (IE) is one of the most serious postimplantation complications. Prosthetic aortic valve IE constitutes 1%–6% of all prosthetic valve IE cases. We present a dramatic echocardiographic case of prosthetic aortic valve IE leading to near‐complete valve dehiscence. Echocardiographic evidence of prosthetic aortic valve rocking motion is indicative of significant dehiscence. Aside from IE, other causes and risk factors for prosthetic aortic valve dehiscence include inflammatory and autoimmune vasculitides, concomitant ascending aorta aneurysm, and aortic root calcification. 相似文献
