“…The overall incidence of pulmonary artery abnormalities in our population was found to be 18.92%, which is comparable to the data collected by Sharma (Sharma et al 1989). Bacha noted pulmonary artery abnormalities in 20% cases (Bacha & Kreutzer 2001).…”

BackgroundThe 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 during this period, were included. Standard cine-angiograms were done to record the pulmonary artery sizes and associated cardiac defects.DescriptionA total of 576 patients with Tetralogy of Fallot were catheterized. Pulmonary Artery abnormalities were present in 109 (18.92%) patients. The commonest abnormality was isolated Left Pulmonary Artery stenosis (n = 60, 10.4%) followed by supra-valvular stenosis (n = 9, 1.6%). Left Pulmonary Artery was absent in seven patients(1.2%), while 1 patient (0.2%) had both absent right and left Pulmonary Arteries with segmental branch pulmonary arteries originating directly from Main Pulmonary Artery. Associated cardiac lesions included right aortic arch in 72 (12.5%), additional muscular Ventricular Septal Defect in 31 (5.4%), Patent Ductus Arteriosus in 31 (5.4%), bilateral Superior Vena Cava 36(6.2%), Atrial Septal Defect 4(0.7%) and Major Aortopulmonary Collateral Arteries in 75(13%) patients. Significant coronary artery abnormalities were present in 28(4.9%) children.ConclusionPulmonary artery abnormalities were present in 18.92% of patients with Tetralogy of Fallot. Isolated Left Pulmonary Artery origin stenosis was the most common abnormality. Significant associated cardiac lesions including Patent Ductus Arteriosus , additional muscular Ventricular Septal Defect, coronary artery abnormalities, bilateral Superior Vena Cava, Atrial Septal Defect and Major Aortopulmonary Collateral Arteries were present in one-third of the patients.

“…The prevalence of this lesion in patients with pulmonary atresia is similar to that reported in smaller series [7,9,12] and in autopsy series [4], but it is much larger than that reported by some others [3]. The prevalence of proximal pulmonary artery stenosis in patients with TOF and critical or severe PS is, however, quite small in our series, in contrast to previous smaller series [5,7,13].…”

“…Children with small ratios are poor candidates for complete repair because of the inability of the small pulmonary arteries to adequately handle the increased blood flow after complete repair. 6,12,13) The present results indicate PSAR is a promising index that can be used to estimate the postoperative success in some cases. The findings of this study have showed that if the PSAR value is less than 0.75, then the PA index and oxygen saturation are lower compared to when the PSAR value is greater than 0.75.…”

SUMMARYThe objective of this study was to determine a reliable, alternative ratio to the pulmonary artery (PA) index, which will help to estimate the adequacy of postoperative pulmonary blood flow in patients with tetralogy of Fallot.We propose the pulmonary segmental artery ratio (PSAR), which is an angiographic measure for the quantitative standardization of the total number of pulmonary segmental arteries in a patient. The expected value of the PSAR is 1 and it is constant after the 16 th week of intrauterine life. Retrospective analysis of the PSAR and PA index calculations in patients with tetralogy of Fallot was conducted. Sixty-one patients were assigned to a moderate or low risk group according to their PSAR; the low risk group included 31 patients whose PSAR was between 0.75-1 (group 1) while the moderate risk group included 30 patients whose PSAR was between 0.50-0.75 (group 2). High risk patients whose PSAR was less than 0.50 were excluded from the study. Postoperative peak right ventricular pressure, the pulmonary artery to systemic pressure ratio, and peripheral arterial oxygen saturation preoperatively after cardiopulmonary bypass were analyzed separately in groups 1 and 2. Postoperative peak right ventricular pressure was lower in group 1 than group 2, while the pulmonary artery to systemic pressure ratio and peripheral arterial oxygen saturation were higher in group 1 than group 2 (P < 0.01).Based on the present findings, it is concluded that PSAR is not as reliable as the Nakata index. However, in cases in which the PSAR and PA index are not correlated, PSAR may be helpful for determining the adequacy of postoperative pulmonary blood flow and postoperative outcomes of patients with hypoplastic pulmonary arteries.
