Background: Systemic light chain amyloidosis is a rare and debilitating disease, especially for which initially presented with digestive tract involvement. Myocardial amyloidosis is highly aggressive with generally poor prognosis and often resulted in missed diagnosis or misdiagnosis with routine examination tools. Multimodality imaging play an important role in diagnosing the amyloidosis effect on multiple organs.

The long-term hypercortisolemia of Cushing disease (CD) may lead to hemodynamic disorders by increasing subclinical cardiac and vascular dysfunction. The purpose of this observational cohort study was to assess the relationship between hemodynamic parameters evaluated via impedance cardiography (ICG) and echocardiographic parameters reflecting left ventricular function in 54 patients newly diagnosed with CD. The parameters assessed via ICG included stroke volume index (SI), cardiac index (CI), acceleration index (ACI), velocity index (VI), systemic vascular resistance index (SVRI), total artery compliance index (TACI).

Left ventricular (LV) thrombus is a serious complication of myocardial infarction (MI) that can lead to a fetal systemic embolism. Although coronary artery bypass graft surgery (CABG) after MI is widely performed, to our knowledge, there are no reports of LV thrombus in the early postoperative period. Here, we report a rare case of a 70-year-old man who underwent off-pump coronary artery bypass grafting (OPCAB) for unstable angina pectoris with reduced left ventricular ejection fraction (LVEF).

Department of Cardiovascular Surgery, Kanazawa University, Takaramachi 13-1, Kanazawa, 920-8641, Japan.
Background: Acute type A aortic dissection (A-AAD) with severe acute aortic regurgitation (AR) and coronary involvement is a potentially fatal condition that causes left ventricular volume overload and catastrophic acute myocardial infarction. We present the successful management of a patient using Impella 5.5 following cardiopulmonary arrest caused by A-AAD with severe acute AR and left main trunk (LMT) obstruction.

Department of Critical Care Medicine, the First Affiliated Hospital of Jinan University, Guangzhou 510632, Guangdong, China. Electronic address:
Previous studies demonstrated that dexmedetomidine (Dex) posttreatment aggravated myocardial dysfunction and reduced survival in septic mice. Yet, whether Dex elicits similar effects in septic patients as defined by Sepsis-3 remains unknown. This study sought to assess the effects of Dex-based sedation on mortality and cardiac dysfunction in septic patients defined by Sepsis-3 and to further reveal the mechanisms in septic rats.
