This case report demonstrate concurrent of two rare complications of true silent inferior STEMI in the poorly controlled diabetic patient with de-novo heart failure, mimicking congenital VSD.This complication of myocardial infarction often have catastrophic manifestations and the presence of this complications of MI with smooth course is very scarce

The clinical manifestation of coronavirus disease 2019 (COVID-19) overlap with other disorders especially cardiovascular diseases (CVD). We report a 58 years old female presented with syncope episodes and dyspnea on exertion with the left atrial mass, candidate for surgical removal and mitral valve replacement. Nearly 3 months later, she developed dyspnea, fever, and a sore throat cause to admit her with suspected COVID-19. During diagnostic evaluation, a larger LA mass detected that seemed to be COVID-19 induced organized thrombus with prosthetic mitral valve malfunction. the mass resected and immunohistochemistry revealed liposarcoma. The unusual early recurrence of liposarcoma and misdiagnosis with COVID-19 induced thrombosis are the hallmark of the present case.

Background: Transverse sinus (TS) is located anterior to the left atrium (LA) and almost posterior to the aortic root. Pericardial fat pad in transverse sinus adjacent to LAA is a rare condition that may resemble LAA thrombosis especially in suspected cases. Case presentation: A 60 years old woman with history of dyspnea on exertion and severe mitral stenosis was planned for percutaneous transvenous mitral commissurotomy (PTMC). In TEE imaging mass-like lesion near LAA was seen and was first thought to be LAA thrombosis. After more TEE angulations and 3D TEE the diagnosis of transverse sinus fat pad (TSFP) was confirmed. Conclusion: Along-side 2D imaging, 3D TEE we can better delineate the complex structure of LA and LAA.
