“…5 Abundant information exists on the prevalence and degree of PA dilation in patients with PAH 2,3 ; however, little is known on the degree and direction of main PA diameter changes over time and particularly its prognostic implications in patients with PAH. We hypothesized that patients with PAH 6 have PA dilation that worsens with time and is associated with worse prognosis.…”

Background and objective A dilated pulmonary artery (PA) is a common finding in patients with pulmonary arterial hypertension (PAH). Little is known on the variations in PA size over time and whether these changes track with disease severity and/or predict long-term survival. Methods We included patients with PAH who had at least two computed tomography (CT) scans of the chest done on different visits. Both scans matched the use of i.v. contrast. Results Pairs of CT scans were compared in 113 PAH patients. During a median (interquartile range (IQR)) time difference between scans of 8 (IQR: 3.5–20.0) months, we noted an increase in main PA diameter of 0.5 ± 1.8 mm (mean ± SD) (P = 0.008). When CT scans were performed >12 months apart (n = 47), the main PA diameter increased or decreased by >1 mm in 40% and 13% of the patients, respectively. An increase in main PA diameter was associated with lower PA compliance, higher right ventricular (RV) systolic pressure, worse RV function and a decline in 6-min walk distance. During a median (IQR) follow-up of 33 (IQR: 4.5–47) months, 53 (46.9%) patients died. The change in PA diameter was a significant predictor of mortality (hazard ratio (HR) per mm increase: 1.33 (95% CI: 1.11–1.61), P = 0.002) when adjusted for difference in time and slice thickness between CT scans, age, gender, PAH aetiology and pulmonary vascular resistance. Conclusion In PAH patients, an increase in CT-derived main PA diameter over time is associated with progression in pulmonary pressures, RV dysfunction, a decline in functional capacity and higher mortality.

“…(1) Other rare causes include chronic inflammation of the PA, right heart endocarditis, amyloidosis, trauma, and severe atherosclerosis (3). Despite the frequent association between chronic obstructive pulmonary disease and pulmonary hypertension, PAD has rarely been reported in this group of patients (1). The presence of multiple arterial aneurysms reported on both the systemic and pulmonary vascular tree has been associated with congenital musculoskeletal abnormalities (4).…”

Pulmonary artery dissection (PAD) is a rare condition that is usually observed in cases with underlying pulmonary arterial hypertension. However, there are several factors related to the etiology of the disease. Presently described is a case of PAD that developed secondary to trauma. A 42-year-old man presented with left chest pain after a fall from a height. His past medical history and physical examination were unremarkable except for pain in the left hemithorax. He had no other complaints. All routine laboratory blood tests were normal. A radiological examination revealed left hilar enlargement and lower lobe PAD. Medical treatment was prescribed. The general condition of the patient was good and as there were no other symptoms, a conservative approach was pursued. In this case, there was pulmonary hypertension, and it is thought that the trauma led to PAD. This is extremely rare in the literature.

“…Few cases are reported in the literature, and most are discovered from autopsies. In most cases, PA dissection is a complication from chronic pulmonary hypertension leading to a PA aneurysm [ 1 – 3 ]. Other cases of reported PA dissection are caused by an extension of a chronic type A aortic dissection through a patent ductus arteriosus or such as a Takayasu’s arteritis complication without pulmonary arterial hypertension (PAH) [ 4 , 5 ].…”

Pulmonary artery dissection is a rare and lethal condition. Few cases are reported in the literature, and most are derived from autopsies. In most cases, pulmonary artery dissection is a complication of chronic pulmonary hypertension leading to pulmonary artery aneurysm but there are other causes. We describe a case of iatrogenic pulmonary artery dissection in an elderly patient with ostium secundum defect. In particular, we describe the role of cardiac magnetic resonance in making this diagnosis and guiding future therapeutic decisions.
