Single ventricle Symptoms and Complications

What is Symptoms of Single ventricle?
In early years, the single ventricle patients have signs of congenital heart disease, such as cyanosis, tachycardia, or slow weight gain in the neonatal or early infancy. More blood to the lungs of patients, early often found nothing. Without treatment, patients with single ventricle of the natural short-lived. Toronto Children's Hospital, according to statistics, 182 cases of death in 117 cases (64%), 50% died after birth, within 1 month, 74% died in the first 6 months. Moodie, such as analysis of 83 cases treated without surgery and has spent the majority of patients in infancy, since the date of diagnosis, 50% of A-type patients with an average of 14 years died. C-type patients worse prognosis, 50% died in 4 years. Whether the pulmonary valve stenosis, the length does not affect life expectancy. The main cause of death was congestive heart failure and arrhythmias, or sudden death, such as unexplained.

Medical examination found symptoms that reduced pulmonary blood flow can be seen from cyanosis and clubbed fingers (toes). Abnormal increase in pulmonary blood flow in chronic congestive heart failure was the growth and development are poor, suffering from weight loss. Congestive heart failure or right atrioventricular valve stenosis without atrial septal defect, the jugular vein engorgement. Such as the right of severe atrioventricular valve insufficiency, the jugular vein and liver have systolic pulse. Showing heart pulse dispersion, as many patients with aortic partial is relative frontal, can palpable perceived closure of aortic valve in the left sternal edge.

Auscultation the first heart sound can be enhanced when the second heart sound is also strong and single, could be heard most of the patients and more loud systolic murmur, grade from pulmonary valve stenosis or subaortic stenosis. Number of patients with pulmonary blood flow in the apical area can hear the left atrioventricular valve stenosis relative diastolic murmur produced.

What are the complications of Single ventricle?
Single ventricle complications include other congenital heart defects, common is pulmonary valve stenosis and atrial septal defect, respectively found in 51% and 27% of patients; coronary malformations can also be combined; the location of conduction system abnormalities and variability, in one out Oral rooms and those rooms - rooms and ventricle - the main artery of the inconsistencies in the relationship between the (left loop) of the patients was abnormal before the atrioventricular node, and in the absence of export chamber of patients, atrioventricular nodal location uncertainty can be positive after the place lateral or anterior; chamber when exports to the left forward position, the total conduction beam debut around the pulmonary valve downstream of the front, closer to the pulmonary valve attachment; if exports to the chamber and the former was the right place, the conduction bundle is located in pulmonary valve under the rear ring; chamber in the absence of exports, and ventricular conduction bundle is located in the rear body.
