Left atrial appendage aneurysm (LAAA) is a rare pathologic entity that can be congenital or, more frequently, acquired. Its complications include arrhythmias and thromboembolic events, palpitations, hiccups, chest pain, dyspnea, and myocardial infarction. LAAA can be isolated or associated with other congenital anomalies such as atrial septal defect, ventricular septal defect, anomalous renal artery, Noonan syndrome, and Hurler‐Scheie syndrome. We report a rare case of giant LAA with intra‐aneurysmal thrombus diagnosed by contrast‐enhanced echocardiography.
Rupture of aortic sinus aneurysms is a rare cardiac malformation that is commonly observed in the right coronary sinus but is rarely observed in the noncoronary sinus. Here, we report a case of aneurysm of the aortic sinus that ruptured into the left ventricular outflow tract and was diagnosed with left ventricular opacification. Left heart echocardiography can clearly demonstrate the structure of the heart and is one of the important diagnostic methods for diagnosing ruptured aortic sinus aneurysms. This observes the perfusion sequence of blood flow to clearly reveal the source, direction, and location of the ruptured aortic sinus aneurysm.
Os cistos sanguíneos no coração são frequentemente reconhecidos como benignos. Geralmente não causam sintomas clínicos e são frequentemente encontrados em bebês menores de dois meses. 1 Na maioria dos casos, os cistos sanguíneos estão nas válvulas cardíacas ou suas estruturas de suporte. 2 Os cistos cardíacos em adultos são extremamente raros, especialmente nas câmaras do coração. Aqui, relatamos um caso de doença cardíaca valvular complicada com um cisto sanguíneo no átrio direito. As ecocardiografias transtorácica, de contraste e esofágica foram utilizadas para examinar o paciente.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
