“…Most reports to date on PAA include a limited number of patients due to the rarity of this entity; it is estimated that there are about 250 aortic aneurysms for every PAA and a large series of 109 571 postmortem exams revealed only eight cases of PAAs. 5,23 However, patients with PAAs require close follow-up to avoid fatal outcomes.…”

Background Pulmonary artery aneurysms (PAAs) are a rare but potentially lethal cardiovascular pathology. PAAs tend to develop in young patients with no gender discrepancy; they are most often associated with congenital heart disorders but also with systemic infections, vasculitis, pulmonary arterial hypertension, chronic pulmonary embolism, and malignancies. Dissection and rupture carry significant morbidity and mortality, thus patients require careful management, especially those with associated pulmonary hypertension. Given the rarity of this condition, physicians have yet to establish standard treatment guidelines. Most studies published to date are case reports with one or two patients; here, we describe our experience with six cases of large PAAs treated surgically at our institution. Methods We identified and retrospectively analyzed clinical data for patients who underwent surgery for PAAs between 2009 and 2017. Results The average age at surgery was 59.73 years, five patients were females, and 83.3% had baseline hypertension. Systolic murmurs were the most common clinical finding. The average aneurysmal size was 65.0 mm. We repaired the PAA with a woven Dacron graft (22‐26 mm) in four patients. We performed concomitant pulmonary valve procedures on five patients: four replacements and one repair. Mean pump and cross‐clamp times were 108.5 and 65 minutes. Operative and 30‐day mortality was 0%. Average length of stay was 10.5 days. Conclusions Postoperative mortality was 0%; all patients showed improvement of symptoms after surgery. These findings confirm that PAA repair has an acceptable risk profile in select patients.

“…About half of the cases are associated with congenital heart diseases, such as patent ductus arteriosus, atrial septal defects, and ventricular septal defects that cause volume and pressure overloading in the right cardiac cavities [ 3 ]. This pathology can also occur due to inflammatory changes in the artery walls resulting from mycosis and syphilis, Behcet's disease, and trauma [ 4 , 5 ]. Isolated aneurysms may be existing with no known pathologies, but they are a very rare entity.…”

Introduction Pulmonary artery aneurysms are a rare entity. Etiologies of these findings are multiple, but they are exceptionally associated with Fallot's Tetralogy. In this study, we present an unusual case of an important aneurysm of the left pulmonary artery associated with Fallot's Tetralogy disease. Case Presentation A 30-year-old woman has been admitted for dyspnea and cyanosis. The data which had been obtained from echocardiography, cardiac catheterization, and angio-magnetic resonance imaging (MRI) suggested the existence of an important aneurysm of the left pulmonary artery associated with a regular Fallot's disease with a pulmonic stenosis. We have noticed the presence of a small restrictive patent ductus arteriosus (PDA). Therefore, the patient was referred to surgical correction. Conclusion Pulmonary artery aneurysms associated with Fallot's Tetralogy are rarely reported. The natural history of these rare arterial aneurysms has to be clarified.

Pulmonary Artery Aneurysm Associated with Bicuspid Pulmonary Valve

A 73-year-old Japanese man was admitted with an asymptomatic pulmonary artery aneurysm. However, chest X-ray and contrast-enhanced thoracic computed tomography revealed a protrusion at the second left branch that in fact was a pulmonary artery aneurysm with a diameter of 50 mm. Transesophageal echocardiography showed a bicuspid pulmonary valve, and cardiac catheterization revealed pulmonary stenosis with a pressure gradient of 45 mmHg, but no other heart diseases were noted. An extremely rare pulmonary artery aneurysm associated with an isolated bicuspid pulmonary valve was diagnosed.
