Efficacy of left atrial plication for atrial functional mitral regurgitation.

Objective: Atrial functional mitral regurgitation (AFMR) is caused by atrial fibrillation and left atrial enlargement. Our study aimed to evaluate the efficacy of left atrial plication (LAP) for AFMR.

Methods: Of 1164 mitral valve surgery patients at our hospital from January 2000 to May 2019, 22 patients underwent surgery for AFMR.

[Redo Right Ventricular Outflow Tract Reconstruction in Adult Patients with Congenital Heart Disease].

Between April 2005 and February 2019, 11 adult patients underwent redo reconstruction of the right ventricular outflow tract. The primary malformation was Fallot's tetralogy in 8, transposition of the great arteries in 2, and pulmonary atresia with intact ventricular septum in 1. Mean age at redo operation was 27.

Rapid detection of human cytomegalovirus UL97 and UL54 mutations for antiviral resistance in clinical specimens.

Drug-resistant cytomegalovirus appears during prolonged anti-cytomegalovirus therapy. Assays for human cytomegalovirus viral protein kinase (UL97) and viral DNA polymerase (UL54) gene mutations conferring drug resistance have been used rather than susceptibility assays to assess clinical specimens. In this study a sensitive system for genotype assay of UL97 and UL54 in clinical specimens with as few as six copies/µg of DNA was developed.
