Epidemiology, Pathophysiology, Diagnosis, and Principles of Management of Takotsubo Cardiomyopathy: A Review.

Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy, is a reversible syndrome commonly found among patients presenting for acute coronary syndromes, especially women. With the COVID-19 pandemic, the incidence of takotsubo cardiomyopathy was dramatically increased. However, this clinical cardiac entity remains underdiagnosed, largely due to the interplay with acute coronary syndrome.

Coronary artery aneurysm: A review.

Coronary artery aneurysm (CAA) is a clinical entity defined by a focal enlargement of the coronary artery exceeding the 1.5-fold diameter of the adjacent normal segment. Atherosclerosis is the main cause in adults and Kawasaki disease in children.

Management of myocardial infarction with Nonobstructive Coronary Arteries (MINOCA): a subset of acute coronary syndrome patients.

Myocardial infarction with non-obstructive coronary artery disease (MINOCA) represents a significant proportion (up to 15%) of acute myocardial infarction (AMI) population. MINOCA is diagnosed in patients who fullfilled the fourth universal definition of AMI in the absence of significant obstructive coronary artery disease on coronary angiography. MINOCA is a group of heterogeneous diseases with different pathophysiological mechanisms requiring multimodality imaging.

Surfing the clinical trials of mesenchymal stem cell therapy in ischemic cardiomyopathy.

While existing remedies failed to fully address the consequences of heart failure, stem cell therapy has been introduced as a promising approach. The present review is a comprehensive appraisal of the impacts of using mesenchymal stem cells (MSCs) in clinical trials mainly conducted on ischemic cardiomyopathy. The benefits of MSC therapy for dysfunctional myocardium are likely attributed to numerous secreted paracrine factors and immunomodulatory effects.

Impact of Coronary Artery Disease and Percutaneous Coronary Intervention on Transcatheter Aortic Valve Implantation.

Introduction: The prevalence of coronary artery disease (CAD) detected in preoperative work-up for transcatheter aortic valve implantation (TAVI) is high. Instead, the management of a concomitant CAD remains unclear. We evaluate the impact of CAD and percutaneous coronary intervention (PCI) on TAVI procedures.
