The Difficult Clinical Decision Of Thrombolytic Therapy For Submassive Pulmonary Embolism In A Community Hospital., Qian Zhang, Jonathan Vayalumkal, John Ricely, Daniel L. Gray, Ahmad Raza

Abington Jefferson Health Papers

Submassive or intermediate-risk pulmonary embolism (PE) occurs when an acute PE episode is associated with radiographic evidence of right heart strain without hemodynamic instability. Further risk stratification is important in determining whether systemic thrombolytic therapy should be administered when weighing the risks and benefits. It includes the risk of death from acute PE versus the risk of bleeding. This decision could be further complicated in institutions where there is a lack of complete therapeutic options, which increases the importance of the expertise of a pulmonologist or an intensivist to decide whether rescue reperfusion is needed. We describe the case of …

Atrioventricular septal defects (AVSD) are a severe congenital heart defect present in individuals with Down syndrome (DS) at a > 2000-fold increased prevalence compared to the general population. This study aimed to identify risk-associated genes and pathways and to examine a potential polygenic contribution to AVSD in DS. We analyzed a total cohort of 702 individuals with DS with or without AVSD, with genomic data from whole exome sequencing, whole genome sequencing, and/or array-based imputation. We utilized sequence kernel association testing and polygenic risk score (PRS) methods to examine rare and common variants. Our findings suggest that the Notch pathway, particularly …

Transcutaneous Energy Transmission: Can We Do It Now?, Yuriy Pya

The VAD Journal

The percutaneous driveline used in contemporary LVADs presents a continuous risk of infection for the duration of support. Minimizing infection in durable mechanical circulatory support systems requires total implantation of all components and energy transfer by means other than percutaneous drivelines. A novel coplanar energy transfer (CET) system, similar to the original transcutaneous energy transfer (TET) design, is unique by incorporating two large rings with coil-within-the-coil topology to ensure strong resonance power. The CET system consists of an internal integrated controller, a battery coupled with an internal thoracic coil ring, and the LVAD pump. External equipment includes a power transmission …

A growing body of evidence shows that altering the inflammatory response by alternative macrophage polarization is protective against complications related to acute myocardial infarction (MI). We have previously shown that oral azithromycin (AZM), initiated prior to MI, reduces inflammation and its negative sequelae on the myocardium. Here, we investigated the immunomodulatory role of a liposomal AZM formulation (L-AZM) in a clinically relevant model to enhance its therapeutic potency and avoid off-target effects. L-AZM (40 or 10 mg/kg, IV) was administered immediately post-MI and compared to free AZM (F-AZM). L-AZM reduced cardiac toxicity and associated mortality by 50% in mice. We …

Angiotensin Inhibition And Gastrointestinal Bleeding Prevention In Patients With Left Ventricular Assist Devices, Phillip A. Weeks

The VAD Journal

Gastrointestinal bleeding remains a common complication in advanced heart failure patients following implantation of continuous-flow left ventricular assist devices. While the cause is likely multifactorial, development of arterial venous malformations in the gastrointestinal mucosa are a key factor. Inhibition of angiotensin II activity has been postulated to disrupt the signaling that promotes angiogenesis in these patients. We aim to review the theoretical basis for angiotensin receptor blockade, which has been proposed and explore the published evidence regarding this therapy and gastrointestinal bleeding in LVAD patients.

Metals are essential cofactors that play a crucial role in heart function at the cell and tissue level. Information regarding the role of metals in the pericardial fluid and its ionome in ischemic heart disease (IHD) is limited. We aimed to determine the association of elements in pericardial fluid and serum samples of IHD patients and their correlation with systolic and diastolic function. IHD patients have been studied with systolic and diastolic dysfunction categorized on the basis of echocardiographic parameters. We measured concentrations of sixteen elements in the pericardial fluid and serum of 46 patients obtained during open heart surgery …

Electrophilic aldehyde (4-hydroxynonenal; 4-HNE), formed after lipid peroxidation, is a mediator of mitochondrial dysfunction and implicated in both the pathogenesis and the progression of cardiovascular disease. Manganese superoxide dismutase (MnSOD), a nuclear-encoded antioxidant enzyme, catalyzes the dismutation of superoxide radicals (O2^•-) in mitochondria. To study the role of MnSOD in the myocardium, we generated a cardiomyocyte-specific SOD2 (SOD2Δ) deficient mouse strain. Unlike global SOD2 knockout mice, SOD2Δ mice reached adolescence; however, they die at ~4 months of age due to heart failure. Ultrastructural analysis of SOD2Δ hearts revealed altered mitochondrial architecture, with prominent disruption of the …
