Also found in: Acronyms.

uni·ven·tric·u·lar heart

an anomaly in which all blood flows through one ventricle or in which the arterioventricular valves are committed to empty into only one chamber in the ventricular mass.

[5] The ventricular interdependence is lost in univentricular hearts, resulting in abnormal systolic and diastolic function of a single ventricle, and is more likely to fail under the stress of surgery and anaesthesia, [6-8] for which the myocardial depressant drugs should be avoided.
In particular, 153 patients harboured defects determining increased volume overload (i.e., defects characterized by left-to-right shunt, such as ventricular septal defect, patent ductus arteriosus, truncus arteriosus, atrial septal defect, and atrioventricular septal defects); 62 patients had heart defects with pressure overload involving the left ventricle (i.e., aortic stenosis and aortic coarctation) or the right ventricle (i.e., tetralogy of Fallot and pulmonary stenosis); and 15 patients were affected with complex cyanotic CHD (i.e., univentricular heart and transposition of the great arteries).
(i) Primary heart transplantation (newborn HTx for HLHS or Ebstein's anomaly) (ii) Eisenmenger syndrome with simple CHD with left to right shunting (acyanotic) (iii) Tetralogy of Fallot (repaired or palliated), and other complex CHD (cyanotic) (iv) Univentricular heart with and without Fontan circulation (v) Systemic right ventricle (CCTGA or TGA after atrial switch operation) HTx: heart transplantation; HLHS: hypoplastic left heart syndrome; CHD: congenital heart disease; CCTGA: congenitally corrected transposition of the great arteries; TGA: transposition of the great arteries.
"The symptoms for a univentricular heart condition include being blue around the mouth and the nails; 40 per cent of our pediatric cardiac patients suffer from this condition, which is a high percentage," said the Consultant.
However, among those with transposition of the great arteries, univentricular heart, or Ebstein anomaly, the prevalence of atrial arrhythmia was 25%-30%.

Sophie was born with a rare univentricular heart. In November, she underwent a five-hour operation in Glasgow's Yorkhill Hospital.
Elevated low-shear blood viscosity is associated with decreased pulmonary blood flow in children with univentricular heart defects.
To that end, they have launched a charity, Jason's Univentricular Heart Transplant Foundation - as requested by Jason himself, from his hospital bed.
