A 3-week-old female white Bengal Tiger cub (Panthera tigris tigris) presented with acute onset tachypnoea, cyanosis and hypothermia. The cub was severely hypoxaemic with a mixed acid-base disturbance. Echocardiography revealed severe pulmonic stenosis, right ventricular hypertrophy, high membranous ventricular septal defect and an overriding aorta. Additionally, an atrial septal defect was foun...

Received: Revised: Accepted: October 18, 2014 February 01, 2015 February 02, 2015 A 5-year-old, 5.4 kg, intact female mixed-breed dog presented with acute respiratory distress. Echocardiography showed pulmonary valvular stenosis with narrowing valvular annulus, ventricular septal defect, overriding aorta and the right ventricular hypertrophy. Other concurrent abnormality included sternal deform...

A two week old girl with tetralogy of Fallot and atrioventricular septal defect underwent palliation, for severe hypoxaemia, by balloon dilatation to the right ventricular outflow tract. This procedure was repeated once over the next eight months without complications. Serial right ventricular angiograms showed growth of the hypoplastic pulmonary ring ("annulus"), trunk, and arteries. Balloon d...

Microdeletion of 22q11 is responsible for DiGeorge syndrome, velocardiofacial syndrome, congenital conotruncal heart defects, and related disorders. We report our experiences on prenatal diagnosis by fluorescence in situ hybridization (FISH) for 22q11 deletion in two fetuses with tetralogy of Fallot. Karyotyping and FISH of the parents revealed that one fetus inherited the disease from maternal...

cy. Aortography was the most reliable method for identification of the AP window when a ventricular septal defect was associated. Associated features included a right aortic arch with mirror image branching in the first case and tetralogy of Fallot with muscular subaortic stenosis in the third case. In the case with the tetralogy of Fallot, the effects of pulmonary stenosis were masked by the l...

The optimal management of patients with tetralogy of Fallot has to consider the individual intra-cardiac anatomy as the most important variable, together with the age and the body weight of the patient. In any case the potential advantages of a primary early repair should be weighted against the experience and expertise of the individual centre and/or surgical team in dealing with tetralogy of ...

A patient with tetralogy of Fallot who developed cyanosis and tachypnea during spontaneous attacks of paroxysmal atrial tachycardia had an increase in right-to-left shunting with a fall in arterial oxygen saturation from 96 to 43%. Duplication of the fast heart rate by atropine and atrial pacing reproduced these hemodynamic changes, while slowing the rate with propranolol reversed this effect. ...

PATIENT Male, 0 FINAL DIAGNOSIS: Tetralogy of Fallot Symptoms: - MEDICATION - Clinical Procedure: - Specialty: Cardiology. OBJECTIVE Unusual or unexpected effect of treatment. BACKGROUND Tetralogy of Fallot (ToF) is the most common form of cyanotic congenital defect. Adult subjects with results of repair of tetralogy of Fallot may present post-surgical consequences that limit their physic...

A hemodynamic model has been developed for the patient with tetralogy of Fallot based on electrical circuit analog and oxygen balance equations. A computer program has been written for the model in the Fortran IV computer language. With the computer model it has been possible to simulate the physiologic conditions during exercise, squatting and hypoxic episodes in tetralogy of Fallot. In additi...
