It was found that although self-fields have strong effect on the FEL resonance, their effects on the two-stream instability is much weaker. (c) 2010 American Institute

“Methods: Twenty consecutive Captisol concentration patients undergoing RFA for AFL late after ASD repair were included. Electrophysiological assessment included multipolar activation, entrainment, and electroanatomic mapping. Clinical, electrocardiograph, and Holter monitoring follow-up was conducted every 6 months.

Results: Mean age was 53 +/- 13 years. Time from surgical repair to RFA was 29 +/- 15 years. All patients had CTI-dependent AFL (20/20). There were 1.6 +/- 0.7 arrhythmias per patient; other arrhythmias included non-CTI-dependent AFL (14), focal atrial tachycardia (two), and atrioventricular nodal reentry tachycardia (two).

Acute success was obtained in 100%. Five patients with recurrent AFL (three CTI dependent, two non-CTI dependent) at 13 +/- 8 months had successful repeat RFA. At 3.2 +/- 1.6 years follow-up since the last procedure, 90% of patients with successful RFA for AFL remained free of their clinical arrhythmia. However, 30% of the original 20 patients had documented atrial fibrillation (AF) 2.1 +/- 1.6 years after the last procedure; five (25%) required AF intervention. One stroke (5%) occurred in the context of late AF.

Conclusion: RFA of AFL occurring late after surgical ASD repair has a low long-term risk www.selleckchem.com/products/AZD0530.html of recurrence, BIIB057 price although 25% of patients required two procedures. However, there is a high late incidence of AF (30%), with an additional 25% of patients requiring intervention for AF. (PACE 2011; 34:431-435).”
“It is now well known that

levels of sperm disomy correlate to levels of infertility (as well as other factors). The risk of perpetuating aneuploidy to the offspring of infertile males undergoing intracytoplasmic sperm injection (ICSI) has become a hotly debated issue in assisted reproduction; however, there remain barriers to the practical implementation of offering sperm disomy screening in a clinical setting. The major barrier is the operator time taken to analyze a statistically meaningful (sufficient) number of cells. The introduction of automated ‘spot counting’ software-hardware combinations presents a potential solution to this problem. In this preliminary validation study, we analyzed 10 patients, both manually and using a commercially available spot counter. Results show a statistically significant correlation between both approaches for scoring of sperm disomy, but no correlation is found when scoring for diploid sperm. The most likely explanation for the latter is an apparent overscoring of two closely associated sperm heads as a single diploid cell.
