Project description:Pulmonary artery (PA) aneurysm is a rare condition, frequently associated with pulmonary hypertension. However, the evolution and treatment of this pathology is still not clear. We report a case of a 45-year-old female patient with giant PA aneurysm associated with rheumatic mitral stenosis and severe pulmonary arterial hypertension. The patient had undergone balloon mitral valvotomy around 7 years back; aneurysm was first identified 3 years back during routine follow-up. The PA aneurysm size, however, had remained almost unchanged with associated severe pulmonary regurgitation. Surgical correction was advised but denied by the patient. To our knowledge, this is the first case report of such a large PA aneurysm in association with rheumatic heart disease. Although medical therapy for pulmonary hypertension was started, surgical correction of the aneurysm was advised in order to prevent the future complications.

Bilateral coronary-to-pulmonary artery fistulas associated with giant aneurysm in an elderly woman: Case report and literature review.

Project description:Coronary artery fistula is an abnormal vascular communication of coronary artery with cardiac chambers or any segment of the systemic or pulmonary circulation. The prevalence is 0.9% of all coronary anomalies. Coronary artery fistula arises from the right coronary artery in approximately 50.0% of patients, from left coronary artery in approximately 42.0% of patients, and from both in approximately 5.0% of patients. Low-pressure structures are the most common sites of drainage of the coronary fistulas. If a large left-to-right shunt exists, it can be associated with potential complications, such as arterial aneurysm. Here we report an extremely rare case of a 76-year-old woman with bilateral coronary-to-pulmonary artery fistulas associated with giant aneurysms, detected by coronary angiography and confirmed with coronary computed tomography.

Pericardiocentesis in Severe Pulmonary Arterial Hypertension Guided by a Pulmonary Artery Catheter.

Project description:Patients, often with underlying rheumatologic disease, may present with pericardial effusions in the setting of pulmonary hypertension (PHTN). Pericardial drainage in PHTN is associated with significant morbidity and mortality. We describe a patient with PHTN who developed cardiac tamponade that was managed safely and effectively with pulmonary artery catheter-guided pericardiocentesis.

A giant basilar artery perforator aneurysm.

Project description:Basilar artery perforator aneurysms (BAPA's) are a rare entity. Their natural history and treatment are unclear. We describe the largest BAPA reported thus far in literature in a 64-year-old Caucasian woman. This patient did not present with subarachnoid hemorrhage, but with left hemiparesis due to pontine ischemia. The aneurysm was initially misdiagnosed as a tumoral mass in a referring center. Angiography confirmed the presence of a BAPA and a flow diverter was successfully placed. This case shows us that a BAPA can mimic a tumoral mass and can cause ischemia due to mass effect without having ruptured. Both conservative and flow diverter placement seems viable treatment options. Individual patient characteristics and preferences should be considered in decision-making for treatment.
