Aortic Valve Replacement: Is Minimally Invasive Really Better? A Contemporary Systematic Review and Meta-Analysis.

In recent years, minimally invasive cardiac surgery has increased in prevalence. There has been significant debate regarding the optimal approach to isolated aortic valve replacement between conventional midline sternotomy and minimally invasive approaches. We performed a systematic review of the contemporary literature comparing minimally invasive to full sternotomy aortic valve replacement.

Mini-sternotomy versus full sternotomy for isolated aortic valve replacement: A single-center experience.

Background: Minimally invasive approaches to isolated aortic valve replacement (AVR) are well-described and widely utilized. While there are numerous proposed benefits, there is limited literature describing significant morbidity or mortality benefits for minimally invasive isolated AVR resulting in hesitancy in its universal adoption. In this retrospective study, we compare the 5-year outcomes of patients undergoing isolated AVR via full sternotomy (FS) or mini-sternotomy (MS).

Mycobacterium chimaera After Aortic Valve Replacement Causing Aortic Rupture and Prosthetic Valve Endocarditis.

A 20-year-old man with severe aortic insufficiency received a mechanical aortic valve replacement. Afterward he subsequently presented with an aortic root dissection, pseudoaneurysm, and prosthetic valve endocarditis requiring surgical reinterventions twice with a positive Mycobacterium chimaera tissue culture despite prolonged antimycobacterial therapy. This is the first reported clinical case of M chimaera in Western Canada and the first with M chimaera-associated aortic dissection and pseudoaneurysm.

Is there a problem with respect? Risk of neochordal rupture.

Purpose Of Review: In this review, we summarize the history of mitral valve repair, discuss the broad principles of neochord preparation and implantation, and highlight comparative outcomes between mitral valve repair strategies while focusing on the risk of neochordal rupture.

Recent Findings: There have been several recent studies comparing outcomes been leaflet-resection and nonresection, neochord-based mitral valve repair. Operative mortality was very low regardless of repair strategy; however, the rate of mitral valve reoperation is lower in those that undergo a neochord-based repair with overall lower mean mitral gradients postrepair.

Systematic review of contemporary outcomes of endovascular and open thoracoabdominal aortic aneurysm repair.

Objective: The purpose of the study was to provide a systematic review of the literature reporting the contemporary early outcomes after endovascular and open repair of thoracoabdominal aortic aneurysms (TAAAs).

Methods: MEDLINE and Embase were searched for studies from January 2006 to March 2018 that reported either endovascular (using branched or fenestrated endografts) or open repair of TAAA in at least 10 patients. Outcomes of interest included perioperative mortality, spinal cord injury (SCI), renal failure requiring dialysis, and stroke.

Myocardial Functional Decline During Prolonged Ex Situ Heart Perfusion.

Background: Myocardial function declines in a time-dependent fashion during ex situ heart perfusion. Cell death and metabolic alterations may contribute to this phenomenon, limiting the safe perfusion period and the potential of ex situ heart perfusion to expand the donor pool. Our aim was to investigate the etiology of myocardial functional decline in ex situ perfused hearts.

Risk of Ischemic Stroke and Peripheral Arterial Disease in Heterozygous Familial Hypercholesterolemia: A Meta-Analysis.

Heterozygous familial hypercholesterolemia (HeFH) is a common genetic disorder predisposing affected individuals to lifelong low-density lipoprotein cholesterol (LDL-C) elevation and coronary heart disease. However, whether HeFH increases the risk of peripheral arterial disease (PAD) and ischemic stroke is undetermined. We examined associations between HeFH and these outcomes in a comprehensive systematic review and meta-analysis.

Anxiety, depression, and health-related quality of life in heterozygous familial hypercholesterolemia: A systematic review and meta-analysis.

Background: Heterozygous familial hypercholesterolemia (FH) is a common genetic disease predisposing affected individuals to a high risk of cardiovascular disease. Yet, considerable uncertainty exists regarding its impact on psychosocial wellbeing.

Objectives: We performed a systematic review and meta-analysis of the association between FH and symptoms of anxiety and depression, and health-related quality of life (HRQL).

Estimating the prevalence of heterozygous familial hypercholesterolaemia: a systematic review and meta-analysis.

Objectives: Heterozygous familial hypercholesterolaemia (FH) confers a significant risk for premature cardiovascular disease (CVD). However, the estimated prevalence of FH varies substantially among studies. We aimed to provide a summary estimate of FH prevalence in the general population and assess variations in frequency across different sociodemographic characteristics.

Diagnosing Lung Cancers through Examination of Micro-RNA Biomarkers in Blood, Plasma, Serum and Sputum: A Review and Summary of Current Literature.

Lung cancer is the leading cause of cancer related morbidity and mortality worldwide. Currently, the vast majority of lung cancers are diagnosed at a late stage, when patients become symptomatic leading to dismal, less than 15% five-year survival rates. Evidence has demonstrated that screening computed tomography scans can be used to detect lung cancer, but these scans have high false positive rates.

Ethanol exposure during gastrulation alters neuronal morphology and behavior in zebrafish.

Ethanol (EtOH) exposure during development has been shown to lead to deficits in fine and gross motor control. In this study we used zebrafish embryos to determine the effects of EtOH treatment during gastrulation. We treated embryos in the gastrulation stage (5.
