Impact of Transcatheter Device Closure of Atrial Septal Defect on Atrial Arrhythmias Propensity in Young Adults.

Atrial septal defect (ASD) is a condition that requires early intervention because of the consequences over the right-side heart. Chronic atrial stretching promotes atrial conduction delay and the imbalance of the conduction homogeneity, which lead to the propensity to atrial arrhythmias (AA). We aim to evaluate the impact of transcatheter closure of ASD on atrial vulnerability markers leading to late AA in young adults.

Dual-Chamber Stimulation with Single-Lead VDD Pacing System in Mustard Surgery.

Sinus node disease is a problem encountered in patients after the Mustard surgery, requiring a pacemaker implantation. The knowledge of the complexity anatomy is crucial because of the possible challenges associated with this procedure. We report a case of a 24-year-old woman presented with symptomatic bradycardia, in which a bicameral stimulation using a single-lead VDD pacing system was successfully performed.

[Treatment of childhood lithiasis using extracorporeal shock wave lithotripsy].

Objectives: We evaluated the efficiency of extracorporeal shock wave lithotripsy (ESWL) in the treatment of pediatric urolithiasis, analyzing results and complications in our series.

Methods/results: 20 patients (16 males and 4 females) with ages from 2 to 17 years were evaluated. Twelve patients presented left side lithiasis (60%).

[Extracorporeal shock-wave lithotripsy as treatment of lithiasis in horseshoe kidney].

Objectives: Horseshoe kidney is the most frequent renal congenital anomaly, with an estimated general population prevalence of 1/400-500. This entity may be asymptomatic for the entire lifetime, or produce symptoms from associated complications such as lithiasis, hydronephrosis, or recurrent infections. The incidence of lithiasis varies between 20% and 80% of the patients.
