“Objective: To determine if achieving bidirectional MI conduction block (MIB) during circumferential pulmonary

vein ablation (CPVA) plus left atrial linear ablation (LALA) affects development of AT.

Methods: Sixty consecutive patients with persistent (n = 25) or paroxysmal (n = 35) AF undergoing CPVA plus LALA at the MI and LA roof were evaluated in a prospective, nonrandomized study.

Results: PVI was achieved in all patients. Bidirectional MI block was achieved in 50 of 60 patients (83%). During 18 +/- 5 months follow-up, 12 patients (20%) click here developed recurrent AF and 15 (25%) developed AT. Patients in whom MIB was not achieved at initial ablation had four times higher risk of developing AT (P = 0.008, 95% confidence interval 1.43-11.48) versus patients with MIB. In 12 patients with AT undergoing repeat ablation, 22 ATs were identified, with reentry involving the MI in nine, the LA roof in six, and the ridge between the LA appendage and left PVs in seven. In patients with MIB at initial ablation, recovery of MI conduction was seen in eight of 13 undergoing repeat ablation.

Conclusions: AT occurring after CPVA plus LALA is often due to incomplete MI ablation, but may also occur at Selleckchem LY2603618 the LA roof, and ridge between the LA appendage and left PVs. Failure to achieve MI block

increases the risk of developing AT. Resumption of MI conduction may also be a mechanism for AT recurrence. (PACE 2010; 460-468).”
“An anonymous on-line survey was sent to 234 intraocular Collamer lens (ICL) (Staar Surgical) AL3818 inhibitor surgeons in 21 countries to determine how many of their ICL cases had been complicated by endophthalmitis between January 1998 and December 2006. A second questionnaire about the infection

details and treatment outcome was sent to those who reported cases of endophthalmitis. Ninety-five (40%) surgeons responded to the survey. They had implanted 17954 ICLs during the study period. Three surgeons reported 1 case of endophthalmitis each, a rate of 0.0167% (95%) confidence interval 0 to 0.036%) or approximately 1 case of endophthalmitis per 6000 ICL implantations. Follow-up details were available in 2 cases. Staphylococcus epidermidis was cultured in both cases, and both were treated without loss of vision. Endophthalmitis may be less common after ICL implantation than after cataract surgery. Further studies are required to define the rate and prognosis for endophthalmitis after ICL implantation to assist in accurate preoperative patient counseling.”
“Objective: We aimed to compare the effects of 2 different antiplatelet agents on platelet activity in patients receiving atorvastatin after coronary artery bypass grafting (CABG).
