The use of transcatheter aortic valve replacement (TAVR) in the United States has been increasing but with variability. We used a 100% sample of Medicare beneficiaries (MBs), from the Centers for Medicare and Medicaid Services database, who underwent TAVR by cardiologists between 2015 and 2019. We stratified data by geographic region, rural/urban a...

Introduction: Heart failure (HF) remains a significant cause of morbidity and mortality in the United States (US). Approximately 6.2 million adults in the United Status have HF and results in an estimated 13.4% of deaths annually. While the development of HF is linked to a variety of risk factors, the incidence and prevalence of methamphetamine-ass...

von Willebrand factor (vWF) aids coagulation at sites of vessel injury. Elevated vWF levels have been associated with an increased risk of ischemic heart disease (IHD); however, it is unclear whether vWF deficiency, seen in patients with von Willebrand disease (vWD), protects people against IHD. We determined and compared the prevalence and risk of...

Background: Nonbacterial thrombotic endocarditis is characterized by the presence of organized thrombi on cardiac valves, often associated with hypercoagulable states. There is a paucity of data regarding the predictors of mortality in patients with nonbacterial thrombotic endocarditis. Our primary aim was to identify predictors of in-hospital mor...
Article
IntroductionTakayasu's arteritis (TA) is an inflammatory condition that affects large vessels and frequently involves the aortic valve causing valve regurgitation. Surgical management is recommended for symptomatic severe aortic regurgitation (AR); however, the optimal surgical approach is yet unclear. This study aims to review surgical treatment o...

Background: Despite the advances in burn care, severe burns still impose significant morbidity and mortality. Severe burns are associated with an inflammatory response that ranges from alterations in vital signs to shock, multiorgan failure, and death. Mesenchymal stem cells (MSCs) are known for their anti-inflammatory and immunomodulatory effects...

Background Viral infections are pervasive and leading causes of myocarditis. Immune-suppression after chemotherapy increases opportunistic infections, but the incidence of virus-induced myocarditis is unknown. Objective An unbiased, blinded screening for RNA viruses was performed after chemotherapy with correlation to cardiac function. Methods Hi...
Article
Background/Introduction: More than moderate tricuspid regurgitation (TR) at baseline is associated with worse outcome in MitraClip patients. The presence of iatrogenic ASD (iASD) may cause right-sided volume overload and lead to adverse events. However, the real effects of iASD are not well-investigated in these patients who are vulnerable to right...
Article
Introduction: Chemotherapy for hematologic malignancies can cause severe cardiomyopathy. Chemotherapeutic agents also induce immune suppression increasing the risk of opportunistic infections. Hypothesis: We have hypothesized that immunosuppression after chemotherapy increases opportunistic viral infections, myocarditis and cardiomyopathy. Methods:...
