Bicuspid Aortic Valve: A Review of its Genetics and Clinical Significance.

Bicuspid Aortic Valve: A Review of its Genetics and Clinical Significance. J Heart Valve Dis. 2016 Sep;25(5):568-573 Authors: Wang L, Ming Wang L, Chen W, Chen X Abstract The aim of this review was to describe recent advancements in the understanding of bicuspid aortic valve (BAV). BAV is the most common congenital cardiac anomaly, and affects between 0.46% and 1.37% of the population. There is a male predominance of approximately 3:1.While isolated BAV is found in certain patients, it is often associated with other congenital cardiac lesions, including dilatation of the thoracic aorta, coarctation of the aorta and abnormalities of the coronary anatomy. In most cases, it remains undetected until the patient contracts infective endocarditis, or calcification occurs. Alternatively, the BAV may remain functional for the entirety of the subjects' life, or it may develop progressive calcification, stenosis and regurgitation, with or without infection. Additionally, BAV is associated with aortic aneurysm formation and aortic dissection. Because BAV is a disease of both the valve and the aorta, surgical decision-making is complicated and remains an important challenge to the surgeon. Although recent reports have improved the current knowledge of the disease, many questions remain unresolved. The present review summarizes the current knowledge regarding the genetic basis of BAV and highlights some of the recent findings that have shed a light on the complications...

In the article “Limb Remote Ischemic Preconditioning for Intestinal and Pulmonary Protection during Elective Open Infrarenal Abdominal Aortic Aneurysm Repair: A Randomized Controlled Trial” (Li C, Li YS, Xu M, Wen SH, Yao X, Wu Y, Huang CY, Huang WQ, Liu KX: Anesthesiology 2013; 118:842 –52), theP values in table 2 are systematically incorrect, given the descriptive statistics. The authors are unable to locate the primary data to recalculate theP values in these tables. The authors believe that the reported descriptive statistics, including tables 1 and 2, are correct, and that the reportedP values are in...

Conclusions Days alive and out of hospital is a feasibly measured patient-centered outcome that is associated with clinically sensible patient characteristics, surgical complexity, in-hospital complications, and longer-term outcomes. Days alive and out of hospital forms a novel patient-centered outcome for future clinical trials and observational studies for adult surgical patients.

AbstractBackgroundContemporary data on mitral valve (MV) surgery in patients with infective endocarditis (IE) are limited.MethodsThe National Inpatient Sample was queried to identify patients with IE who underwent MV surgery between 2003 and 2016. We assessed (a) temporal trends in the incidence of MV surgery for IE, (b) morbidity, mortality, and cost of MV repair vs replacement, and (c) predictors of in ‐hospital mortality.ResultsThe proportion of MV operations involving patients with IE increased from 5.4% in 2003 to 7.3%, and the proportion of MV repair among those undergoing surgery for IE increased from 15.2% to 25.0% (Ptrend

The American College of Surgeons' National Quality Improvement Program (NSQIP) database can be used to assess trends and outcomes of ruptured abdominal aortic aneurysm (rAAA) repair. The purpose of this study is to examine the morbidity and mortality for ruptured endovascular (rEVAR) and ruptured open (rOPEN) aneurysm repair compared with elective endovascular (EVAR) and elective open (OPEN) aneurysm repair.

AbstractPurpose of reviewThe purpose of this review was to evaluate the complexities and challenges associated with transcatheter mitral valve replacement and review the existing data.Recent findingsMany patients with mitral valve disease are not candidates for cardiac surgery and are in need of less invasive transcatheter therapies. The first transcatheter mitral valve replacement (TMVR) in a native valve was performed in 2012. However, the complexities and variability of the mitral valve anatomy and its relationship to neighboring structures have resulted in slower progress with this new therapy compared to the rapid upt...

AbstractMucopolysaccharidoses (MPS) are inborn errors of metabolism produced by a deficiency of one of the enzymes involved in the degradation of glycosaminoglycans (GAGs). Although taken separately, each type is rare. As a group, MPS are relatively frequent, with an overall estimated incidence of around 1 in 20,000 –25,000 births. Development of therapeutic options for MPS, including hematopoietic stem cell transplantation (HSCT) and enzyme replacement therapy (ERT), has modified the natural history of many MPS types. In spite of the improvement in some tissues and organs, significant challenges remain unsol ved, in...
