Endovascular Treatment of Complicated Popliteal Aneurysms Using the Novel "Trap and Fix" Technique.

Herein, we present 2 patients with lower limb ischemia caused by complicated popliteal aneurysms with thrombosis and distal embolization, compromising blood flow to the foot. In both cases, covered stents were first implanted guided by intravascular ultrasound and computed tomography angiography, respectively. After "trapping" the thrombi, mechanical thrombectomy or further stent implantations were performed, "fixing" the remaining lesions and preventing embolization.

Cryoballoon vs radiofrequency ablation of atrial fibrillation: insights from the Veterans Healthcare System.

Purpose: Catheter ablation is considered the mainstay treatment for drug-refractory atrial fibrillation (AF). The aims of our study were to compare the efficacy and safety of the most two currently approved approaches (point-by-point radiofrequency ablation (RFA), either with contact force (CF) or without contact force (nCF) catheters, and cryoballoon ablation (CBA)) in the Veterans Healthcare System.

Methods: We performed a retrospective study of patients who underwent ablation for treatment of AF at the veterans affairs healthcare system between 2013 and 2018.

Association of sexually-transmitted infection and African-American race with Streptococcus agalactiae colonization in pregnancy.

Background: Group B Streptococcus (GBS) remains a significant cause of neonatal infection, but the maternal risk factors for GBS colonization remain poorly defined. We hypothesized that there may be an association between antibiotic exposure during pregnancy and GBS colonization and/or the presence of inducible clindamycin resistance (iCLI-R) in GBS isolates from GBS-colonized pregnant women.

Methods: A retrospective cohort study was performed at Louisiana State University Health Sciences Center - Shreveport including demographic and clinical data from 1513 pregnant women who were screened for GBS between July 1, 2009 and December 31, 2010.

Management of tachyarrhythmia during pregnancy.

Maternal tachyarrhythmia is a common complication during pregnancy due to hormonal changes that enhance pre-existing arrhythmias or induce new arrhythmias in the presence of congenital heart defects in pregnant females. Presence of tachyarrhythmia during pregnancy poses risk to the mother and fetus, calling for proper treatment with medications. Use of antiarrhythmic drugs in cases of maternal tachyarrhythmia must give due consideration of potential teratogenic side effects.
