A 63-year-old mand with permanent atrial fibrillation through five years presents to the emergency room with dyspnea and an ECG showing pre-excited afib. The ECG was initially perceived as afib with bundle branch block and treated with digoxin. After that, treatment with amiodaron was given; also without success.

A novel algorithm for classification of interatrial communications within the oval fossa in the newborn.

Background: An interatrial communication is present in most neonates. The majority are considered the "normal" patency of the oval foramen, while a minority are abnormal atrial septal defects. Differentiation between the two with transthoracic echocardiography may be challenging, and no generally accepted method of classification is presently available.

Repeatability and Reproducibility of Neonatal Echocardiography: The Copenhagen Baby Heart Study.

Background: The Copenhagen Baby Heart Study (CBHS) is a population-based cohort study of neonates (N = 25,000), including echocardiography. Echocardiography in neonates is mainly focused on congenital heart disease (CHD), whereas general aspects of cardiac dimensions and function in neonates without CHD remain to be further addressed.

Purpose: This study was conducted to assess the reliability of neonatal echocardiography and validity of echocardiographic methods used in the CBHS.
