Abstract Background The anomalous origin of one pulmonary artery is a rare malformation, which so far has mainly been found as an anomalous origin from a different site of the aorta, accounting for 0.12% of all congenital heart diseases. This case report introduced a very rare case of the anomalous origin of one pulmonary artery which had never reported in the clinic. Case summary A 2-year-old boy with a 6-month history of shortness of breath and recurrent respiratory infection, was diagnosed left pulmonary artery (LPA) directly arising from the right ventricle by transthoracic echocardiography and multidetector computed tomography without a deletion in the region of 22q11. Eventually, the LPA was further conformed that arised from the right ventricle during the operation, and was corrected with a well clinical outcome. Discussion The surgical technique for repair of this anomalous LPA was not difficult in our case. However, the embryonic development of the present case still could not be completely explained by the current embryologic postulates since it was a new malformation that never reported. Due to its rarity, there is still much to learn about the origin and development of the pulmonary arteries that possibly develop prenatally.

The purpose of the study was to study the pulmonary vessels in patients with pulmonary hypertension using Computed Tomography scan (CT) This is a prospective ,analytical study. this study was conducted at Khartoum Hospital (Sudan); in the period between November 2020 - January 2021 a sample of (100) patients with clinically diagnosed as pulmonary hypertension was enrolled, their mean ages were (47.92 ± 19.03) years, the sample included both genders, (42) patients were females while (58) were males and their ages were ranged from (3 - 80) years old. (CTPA) scans were acquired, all patients were examined by using multislice (CT) scanner, the data collected by special designed sheet from findings and analyzed statistically by using an (SPSS) Statistics software package. The sample was directed to study the relationship of pulmonary hypertension with the presence of pulmonary vessels measurements; the patient's age and gender correlation with the pulmonary hypertension were investigated. The results find that the right and left main pulmonary arteries diameters changes were found to be significantly related to the presence of pulmonary hypertension, while there was no significant difference in the main pulmonary artery diameters measurements. The study concluded that CT for pulmonary artery plays an important role in the diagnostic evaluation of patients with pulmonary hypertension this due to it is easily accessible and excellent non-invasive method for the visualization and measurement of pulmonary artery and to know the possible cause of pulmonary hypertension.

ABSTRACT CONTEXT: Obstruction of the right ventricular outflow tract due to metastatic disease is rare. Clinical recognition of cardiac metastatic tumors is rare and continues to present a diagnostic and therapeutic challenge. CASE REPORT: We present the case of a patient who had severe respiratory insufficiency and whose clinical examinations revealed a giant tumor mass extending from the right ventricle to the pulmonary artery. We discuss the diagnostic and therapeutic options. CONCLUSION: In patients presenting with acute right heart failure, right ventricular masses should be kept in mind. Transthoracic echocardiography appears to be the most easily available, noninvasive, cost-effective and useful technique in making the differential diagnosis.

Pulmonary embolism was produced in 30 closed-chest 8-kg dogs with polystyrene spheres, glass beads, or blood clots of precise graded size. The sizes matched selectively the internal diameter of pulmonary arteries from lobar branches (5–6 mm) down to atrial arteries (0.17 mm). Emboli were injected into the right atrium until the pressure in the pulmonary artery rose 5–10 mm Hg. The number of emboli of a given size required to produce this incipient pulmonary hypertension was compared with the number of vessels of that same size as determined from the literature as well as by postmortem injection with Schlesinger mass. The number of emboli bore a constant relation to the number of vessels of that same size. With each size, the majority of vessels had to be occluded before pulmonary hypertension appeared. This was true even in the absence of anesthesia. The results support the thesis that mechanical blockade rather than vasoconstriction is the mechanism by which pulmonary hypertension is produced by emboli occluding pulmonary arterial (as opposed to arteriolar) vessels.

The relationship between instantaneous distending pressure and diameter of the pulmonary artery was studied in 18 living thoracotomized dogs. An electrical caliper with adequate recording characteristics was developed for instantaneous diameter measurement. Control observations were made over a range of pressures induced by rapid, right heart dextran-infusion and were compared with those obtained during norepinephrine administration. Results indicate: a) the pulse contours of the pulmonary artery pressure and diameter are essentially identical, indicating negligible inertance and viscous resistance of the vessel wall, b) the mean change in average radius during a cardiac cycle was ±7.8% ± 2.86 S.D. ± .32 S.E.M. (0.48%/cm H2O pulse pressure) under control conditions, c) the ratio of change in radius to pulse pressure, R/P, showed a significant decrease during norepinephrine administration when compared to control values within the same pressure range (P < .01) and d) the cross-sectional area of the main pulmonary artery exceeded that of the right and left combined.

AbstractWe describe the case of a 9-year-old girl demonstrating isolated absence of the coronary sinus with abnormal coronary venous drainage into the main pulmonary artery. Coronary angiography showed normal coronary arterial trees and contrast medium from both coronary arteries drained into the main pulmonary artery via an abnormal cardiac vein on the anterior wall of the right ventricle.
