Abstract

The purpose of this study was to identify the morphologic characteristics and other risk factors that may predispose patients with mixed totally anomalous pulmonary venous connection to continuing high mortality after surgery. Fifty-seven consecutive patients aged 15 days to 18 years (median, 6 months) underwent rechanneling of mixed totally anomalous pulmonary venous connection. Twenty-three patients had "2+2" pattern (I category), 29 had "3+1" pattern (II category), and 5 patients had pulmonary venous connections of different combinations (III category). Obstructive patterns involving one or more pulmonary veins were present in 19 (33.3%) patients. Operative and late mortality rates were 19.3% and 4.3%, respectively. At a mean follow-up of 63.26 +/- 58.47 months, actuarial survival was 86.9% +/- 0.07% in category I, 86.2% +/- 0.06% in category II, and 20.0% +/- 0.18% in category III (log-rank, P = .001), respectively. At their last follow-up, all survivors (n = 43) had a Ross clinical heart failure score of 0 to 2. Patients with a "2+2" pattern of mixed totally anomalous pulmonary venous connection constitute the safe anatomic category for rechanneling, followed by the "3+1" variety.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
