Surgical Repair of Giant Dissecting Pulmonary Artery Aneurysm Associated with Atrial Septal Defect and Pulmonary Arterial Hypertension: A Case Report

Pulmonary artery aneurysm (PAA) and pulmonary artery dissection (PAD) are rare and potentially fatal conditions that may lead to pulmonary artery (PA) rupture and cardiac tamponade. PAA is often associated with other cardiac and congenital heart diseases, such as atrial septal defect (ASD). We report a case of a patient with ASD and a giant dissecting PAA who underwent surgical repair to prevent potentially fatal outcome and discuss the probable etiologies of this case. We present a rare case of a 50-year-old woman with a secundum ASD and severe pulmonary arterial hypertension (PAH) who developed a giant PAA of 114 mm with dissection. The PAA caused extrinsic compression of the left main coronary artery (LMCA), which was misdiagnosed as coronary artery disease (CAD) at local hospital. Right heart catheterization revealed PAH of 73 mmHg and she was referred to our center for further treatment. After 4 months of lowering PAH treatment, she underwent successful surgical repair of the PAA to release the compression of LMCA, as well as mechanical valve replacement, fenestrated ASD closure and tricuspid valvuloplasty. She had an uneventful recovery and showed significant improvement in pulmonary hemodynamics and clinical symptoms at one-year follow-up. PAA with dissection is a rare complication of ASD and PAH that can potentially be fatal. Patients with large or symptomatic PAA and PAD may require early surgical intervention, particularly if they experience compression of nearby structures or are at risk of rupture. It is crucial to promptly refer and consult with specialists and ensure optimal preoperative hemodynamic management to enhance patient outcomes.

Surgical management of a giant pulmonary artery aneurysm in a patient with ischaemic heart disease - a case report.

Association of Pulmonary Artery Aneurysm with Ischemic Heart Disease is uncommon, and its surgical management has been rarely described in the literature. Surgical intervention should be individualised according to the coexisting diseases and comorbidities to achieve optimal outcome. We report a case of a 76-year-old man with background history of coronary artery stenting due to ischaemic heart disease. The patient presented with features of coronary compression due to giant pulmonary artery aneurysm. He was operated with replacement of aneurysmal pulmonary trunk with 25 mm Hancock conduit.

A bilateral lung transplant and giant pulmonary artery aneurysm reconstruction with an aortic graft in a woman with pulmonary hypertension.

An aneurysm of the pulmonary artery is a rare but severe complication in patients suffering from pulmonary arterial hypertension. For these patients, a lung or heart-lung transplant is the only definitive therapy available. Our goal was to show a reconstruction strategy in a patient with a mismatch between the pulmonary artery and the donor aorta.

Surgical management of giant pulmonary artery aneurysms in patients with severe pulmonary arterial hypertension.

Giant aneurysm of the pulmonary artery (PAA) is an extremely rare condition that may develop in patients with pulmonary arterial hypertension (PAH) which may be complicated by rupture, dissection or intravascular thrombus formation. The aim of this study was to examine available literature with regard to surgical strategies in patients undergoing transplantation for PAH with PAA. These patients were traditionally considered for heart-lung transplantation but more recently, there have been reports of successful lung transplantation with reconstruction of the pulmonary artery. Unless there is a mandatory indication for heart-lung transplantation, patients with PAH and PAA can undergo lung transplantation and reconstruction of the pulmonary artery without compromising the outcome.

Management of Giant Pulmonary Artery Aneurysm with Quadricuspid Valve Stenosis

AbstractThe pulmonary artery aneurysm (PAA) is a rare disease with no well-defined guidelines about the diagnostic criteria and its management. In fact, the indications for surgical treatment and the type of surgical approach are not clear. However, in case of giant PAAs with hypertension and pulmonary valve abnormalities, surgery should be considered as an effective and safe approach to prevent dissections or ruptures. In this report, we describe a successful case of surgical repair, using a Bioconduit with a pericardial patch to recreate the pulmonary artery bifurcation in a 72-year-old male with aneurysm of the pulmonary artery (max diameter: 72 mm), associated with quadricuspid pulmonary valve stenosis and pulmonary hypertension. The procedure was uncomplicated and the follow-up computed tomography scan at 4 months showed correct positioning of the graft with no sign of contrast leakage.

Pulmonary mucormycosis causing a mycotic pulmonary artery aneurysm

Mycotic pulmonary artery aneurysms requiring pneumonectomy are extremely rare. We present a severely breathless immunocompromised diabetic middle-aged female patient. CT pulmonary angiogram revealed a giant pulmonary artery aneurysm with impending rupture in the right lung. We did an emergency right pneumonectomy under cardiopulmonary bypass support. Histopathology report of the lung specimen confirmed mucormycosis. She received amphotericin B after the procedure. The patient had a prolonged postoperative hospital stay and succumbed to sepsis. Mycotic pulmonary artery aneurysm portends very high morbidity and mortality in immunocompromised patients.

Giant Pulmonary Artery Aneurysm in Bicuspid Pulmonary Valve: Does the Right Side Mimic the Left One?

Bicuspid pulmonary valve is a rare echocardiographic finding, particularly if not associated with other congenital heart diseases. We report the incidental case of a severe giant pulmonary arterial aneurysm associated to bicuspid pulmonary valve in an asymptomatic 79-year-old patient. Multimodality cardiac imaging was important for the correct diagnosis and to exclude any other potential complication. (Level of Difficulty: Beginner.)

Heart-lung transplantation for idiopathic pulmonary arterial hypertension and giant pulmonary artery aneurysm \u2013 case report

BackgoundIdiopathic pulmonary arterial hypertension (IPAH) is a rare condition that requires lung transplantation in patients’ refractory to medical therapy. Pulmonary artery aneurysm (PAA) is a documented complication of IPAH however, optimal management and timing of intervention for this rare entity is not well understood.Case reportWe report a case of a 51-year-old female who underwent heart-lung transplantation for IPAH and giant PAA. The extreme size of the PAA and underlying pathology encountered in this case precluded both lung transplantation and conventional aneurysm repair.ConclusionThis case demonstrates that heart-lung transplantation is a good surgical option for IPAH complicated by giant sized PAA and right heart failure.

A case of giant main pulmonary artery aneurysm associated with complicated congenital heart disease and simultaneous chronic pulmonary artery dissection

BackgroundPulmonary artery aneurysm (PAA), usually associated with congenital heart disease (CHD), is a very rare clinical condition. Pulmonary artery dissection (PAD) is considered the most life-threatening complication of PAA, and patients can progress from being asymptomatic to sudden death. We report the following case of PAA associated with complicated congenital heart disease and simultaneous chronic PAD. To our knowledge, few such complicated cases have ever been reported.Case presentationA 36-year-old male presented to our hospital with a 10-year history of heart fatigue after activities and aggravated for 2 years. Computed tomography angiography (CTA) and echocardiogram showed a giant main pulmonary artery aneurysm (14 cm) with complicated congenital heart disease (a small patent ductus arteriosus, ventricular septal defects, aortic coarctation). Chronic PAD, which was mistaken for a pulmonary valve before operation, was detected during surgery.ConclusionsPAA associated with complicated CHD and simultaneous PAD is very rare, and its clinical symptoms are varied. Radiologists and surgeons should pay attention to determining whether this patient simultaneously had PAD when PAA was detected on preoperative CTA imaging.

Succesfull management of a giant pulmonary artery aneurysm associated with severe congenital pulmonary valve stenosis in an adult patient

Pulmonary artery aneurysms are rare entities usually associated with congenital anomalies that increase blood flow/pressure in the pulmonary circulation, like left to right shunts and/or severe pulmonary valve pathologies. Clear re-commendations about their management are lacking. We report on a case of severe congenital pulmonary valve stenosis associated with a giant pulmonary artery aneurysm, secondary right ventricular outflow tract obstruction and right to left atrial shunt. We discuss the diagnostic pathway, therapeutic approach and patient evolution. The case report proves that a complete imaging of the heart and blood vessels is mandatory with severe pulmonary valve stenosis, in order to better describe its repercussions on the right ventricle and pulmonary circulation. They might be under detected by simple tran-sthoracic echocardiography but their presence has important therapeutic implications.

David's procedure for pulmonary artery aneurysm

Pulmonary artery aneurysm (PAA) is a rare entity with fatal complications. Its silent course contributes to large aneurysms with compression symptoms. We present a 39-year-old female idiopathic pulmonary arterial hypertension patient with a giant PAA causing severe pulmonary regurgitation (PR) and symptomatic left main coronary artery compression (LMCA). Since she had a failed LMCA stenting attempt, she underwent surgery. A valve-sparing David-like pulmonary trunk reconstruction and coronary artery bypass were performed. This case illustrates that David-like reconstruction procedure can be applied to the PAA with severe PR.
