BACKGROUND The objective of study was to determine pulmonary artery variations and other associated cardiac defects in patients with Tetralogy of Fallot. This cross-sectional, descriptive study was carried out at The Children's Hospital and the Institute of Child Health, Lahore, from January 2006 to December 2012. All patients with Tetralogy of Fallot, who underwent cardiac catheterization duri...

BACKGROUND Although catheter ablation has been used to target the critical isthmuses for re-entrant monomorphic ventricular tachycardia in tetralogy of Fallot, the anatomy and histology of these regions have not been fully characterized. Autopsy hearts with tetralogy of Fallot were evaluated to clarify the pathological substrate. METHODS AND RESULTS Twenty-seven hearts with the diagnosis of t...

Experience with the first 100 cases with tetralogy of Fallot subjected to intracardiae repair are presented. In this series there was an early hospital mortality of 12 per cent and 6 late deaths occurred. Eighty out of 82 survivors were available for follow-up and 33 of these underwent postoperative catheterization studies. The functional status of the survivors revealed excellent results in 89...

Anatomy Tetralogy of Fallot represents 10% of all congenital heart defects and is the most common form of cyanotic heart disease. A Danish scholar, Nicholas Steno, first described the defect in 1673, 200 years before Fallot. One hundred years later, numerous other reports were published from postmortem cardiac examinations. The French physician, Arthur Fallot, was the first to make an accurate ...

Results RV function measured by CMR was negatively correlated with peak systolic strain of mid RV free wall (P=0.038, Pearson r=-0.357) and also negatively correlated to both mean of strain (P=0.028, Pearson r=-0.376) and SR (P=0.035, Spearman’s rho=-0.362) of basal , mid and apical segments of RV. Conclusions Overall, in the assessment of RV function , echocardiographic measurement of strain a...

This paper studies hemodynamic changes after repairing congenital valvular heart disease. Two categories of Tetralogy Fallot (TOF) and (ASD Primum) were collected from the Nasiriyah Heart Center between January 2015 February 2022, with findings for 50 patients (28 TOF & 22 ASD Primum). The results showed that spo2 value before Surgery was low compared to its Surgery, which due existence ste...

Ventricular arrhythmias in patients after total surgical repair of tetralogy of Fallot have been associated with late sudden death. In this large multicenter retrospective study of 359 patients with postoperative tetralogy of Fallot, spontaneous ventricular premature complexes (VPCs) on 24. hour ambulatory electrocardiographic monitoring and laboratory-induced ventricular tachycardia (VT) by el...

IN RECENT YEARS the morphological features of the major portions of the atrioventricular (A-V) conduction system of human hearts that were afflicted with various congenital anomalies have been described.1-6 These reports have contrasted the anatomy of the A-V conduction system in examples of ventricular septal defect (VSD) and tetralogy of Fallot with that configuration found in defects of the ...

OBJECTIVE To evaluate short-term and medium-term results of intracardiac correction of tetralogy of fallot in the first year of life. METHODS From January 1996 to October 2004, 67 consecutive infants ranging in age from 1 to 11 months (mean: 7.2 months) and weighing from 4 to 10 kilograms (mean: 7.1 kilograms) underwent elective total correction of tetralogy of fallot. The surgery was accompl...

PURPOSE To test the potential of magnetic resonance imaging (MRI) in early detection of left ventricular (LV) dysfunction in patients with pulmonary regurgitation and normal LV ejection fraction after repair of tetralogy of Fallot. MATERIALS AND METHODS Patients (n = 18) with repaired tetralogy of Fallot and pulmonary regurgitation were prospectively recruited. Healthy volunteers (n = 10) wer...
