Preoperative coronary angiography is warranted in individuals 50 years of age and older, as well as in those younger than 50 years who have significant risk factors for CAD. This study sought to determine the outcome effect of concomitant tricuspid valve operation for regurgitation during pericardiectomy for constrictive pericarditis. This cohort study included 310 patients with mild or greater tricuspid valve regurgitation who underwent pericardiectomy for constrictive pericarditis from 2000 to 2016 at the Mayo Clinic in Rochester, Minnesota. Patients were divided into 2 treatment groups tricuspid valve operation (n= 68) and no tricuspid operation (n= 242). Survival analysis, proportional odds models, and landmark analysis were carried out to estimate the treatment effects of tricuspid valve operation. Tricuspid valve regurgitation was graded mild in 203 (65%) patients, moderate in 69 (22%), and severe in 38 (12%). Tricuspid valve operation included repair in 54 patients (17%) and replacement in 14 (5%). Mechanical circulatory support was used more commonly in the intervention group (15% vs 5%; P= .009), but rates of stroke (3% vs 2%; P= .210) and mortality (9% vs 6%; P= .trictive pericarditis. Operation appears protective against long-term mortality, residual tricuspid regurgitation, and right ventricular enlargement.Here we present an easy flow cytometry protocol to study the viability of Helicobacter pylori which also enables the detection of even low live bacteria densities. This protocol has potential utility for a fast and accurate assessment of experimental eradication methods against H. pylori.We report the development of ddPCR assays for single and simultaneous detection of the bacterial pathogens Flavobacterium psychrophilum and Yersinia ruckeri in water from land-based recirculation aquaculture systems (RAS), producing Atlantic salmon (Salmo salar) smolt. The method was tested
