Variable size of aortic subvalvular pseudoaneurysm.

ABSTRACT: Aortic subvalvular pseudoaneurysms (PSA) are particularly subjected to strain and shear stress forces from blood flow and therefore their size can vary along the heart cycle. Here we describe a case of an aortic subvalvular PSA that shows significant variation in size between systolic and diastolic phase during retrospective ECG-triggered cardiac computed tomography angiography.

Mitral-Aortic Intervalvular Fibrosa Pseudoaneurysm.

Project description:Pseudoaneurysm of the mitral aortic intervalvular fibrosa (MAIVF-P) usually ensues as a complication of endocarditis or aortic valve surgery. When large, symptomatic or related to complications (rupture, compression of adjacent structures, embolic events, mitral regurgitation or heart failure) it warrants surgical excision. The natural course of uncomplicated/asymptomatic MAIVF-Ps is largely unknown since most patients are offered surgery. Increased surgical risk imposed by repeat operations in the majority of these patients is an important consideration and conservative treatment should not be excluded in selected cases. Herein we present two illustrative cases of MAIVF-P manifesting with significant arrhythmogenesis and complex endocarditis respectively. Both patients were managed conservatively. By briefly reviewing the existing literature, we discuss important diagnostic and therapeutic issues for MAIVF-Ps. To our knowledge complex ventricular arrhythmia has not been previously described as a prominent manifestation of MAIVF-P.

Surgical management of a giant ascending aortic pseudoaneurysm.

Project description:Aortic pseudoaneurysm is a rare, life-threatening complication after cardiac or aortic root surgery. When a pseudoaneurysm has eroded bony structures in the chest, the surgeon's challenge is to choose the safest approach for sternotomy. Herein, we report the case of a 74-year-old woman who presented with a giant pseudoaneurysm of the ascending aorta, 8 years after undergoing aortic valve replacement. The 8.9×5.8-cm formation arose in the anterior aortic sinus, extended to the retrosternal region, exerted mass effect on the main pulmonary artery, and eroded the bony structures of the sternum and medial upper chest. A new aortic valved tissue conduit was placed, and the coronary arteries were reimplanted. The patient recovered without neurologic sequelae. We discuss the characteristics of this case and explain our surgical decisions.

Unruptured Pseudoaneurysm of the Mitral Aortic Intervalvular Fibrosa.

Project description:A 38-year-old female with a history of primary mitral regurgitation experienced shortness of breath even at rest 4 months previously. Cardiac computed tomography showed a large unruptured aneurysm arising from the mitral-aortic intervalvular fibrosa adjacent to the anterior mitral leaflet. The patient passed away because the pseudoaneurysm ruptured into the pericardium. (Level of Difficulty: Beginner.).

Aortic calcification correlates with pseudoaneurysm or penetrating aortic ulcer of different etiologies.

Project description:Chronic risk factors for pseudoaneurysm (PSA) or penetrating aortic ulcer (PAU) have not been fully clarified. This study aims to evaluate the association of aortic calcification with PSA or PAU of different etiologies. Totally 77 pseudoaneurysms, 80 PAU, and 160 healthy controls (HCs) were retrospectively included, of which 30 were infected, 34 were immunological, and 93 were atherosclerotic etiologies. The aortic calcification status, position of aortic tears/ulcers, and risk factors for disease or acute aortic syndrome (AAS) were identified. Atherosclerotic patients aged more than 65 and infective patients aged more than 60 had significantly higher calcification scores. The immunological group had a lower level of calcification in the infrarenal aorta. For patients of infective or atherosclerotic etiology, 60% (18/30) and 60.22% (56/93) of the tears/ulcers occurred at the aortic parts with the highest level of calcification. Patients with longitudinal calcification exceeding 1/3 of the aortic arch had an increased risk of acquiring diseases (OR = 13.231). The presence of longitudinal calcification of the descending aorta or cross-sectional calcification of the infrarenal aorta increased the risks of acquiring diseases (OR = 8.484 and 8.804). After adjusting for age, longitudinal calcification of the descending aorta exceeding 1/3 length was found to be associated with AAS (OR = 4.662). Tears/ulcers of pseudoaneurysm and PAU were both generally found at the part of the aorta with most calcification. Distinct aorta calcification characteristics were observed for lesions of different etiologies. Longitudinal thoracic and cross-sectional infrarenal abdominal aortic calcification increased the risk of acquiring diseases, and descending aortic calcification was associated with symptomatic patients.

Mycobacterium chimaera Infection After Aortic Valve Replacement Presenting With Aortic Dissection and Pseudoaneurysm.

Project description:We present a case of Mycobacterium chimaera infection presenting with aortic dissection and pseudoaneuysm in a 22-year-old man with a past history of aortic valve replacement. Clinicians should consider M. chimaera infection in those presenting with aortic dissection as a late complication of cardiovascular surgery.

Brucella endocarditis of pseudoaneurysm of an aortic composite graft.

Project description:The occurrence of Brucella endocarditis following Bentall operation is a rare and life threatening condition, particularly when it is complicated by development of a pseudoaneurysm. Here we present a 40-year-old veterinarian with bicuspid aortic valve, who developed type A aortic root dissection and required Bentall operation. His past medical history was positive for an episode of treated brucellosis. Four months after the operation, he developed signs, symptoms and serological findings of brucellosis for the second time and was treated with antibiotics. Then after he was well untill about 14 days prior to his recent admission, when he again developed hip pain, fever, shortness of breath, profound fatigue and weakness. His transthoracic echocardiography was suggestive of endocarditis. A transesophageal echocardiogram revealed detachment of valve-conduit from the annulus and the mitral-aortic intervalvular fibrosa and the presence of a large aortic pseudoaneurysm with multiple vegetations attached to its Dacron walls. A huge pseudoaneurysm was detected at surgery and the whole valve-conduit was replaced with a 25 mm homograft. Blood and vegetation cultures turned to be positive for Brucella melitensis. Early echocardiographic diagnosis and prompt surgical intervention were helpful for survival of our patient who had aortic pseudoaneurysm complicated by Brucella endocarditis.

Endovascular treatment for traumatic thoracic aortic pseudoaneurysm: a case report.

Project description:Cases of an endovascular treatment for traumatic aortic injury are extremely rare. A prompt diagnosis of traumatic thoracic aortic pseudoaneurysm through a 3-dimensional computed tomographic angiography of aorta and emergency repair are mandatory to rescue the life-threatening condition. An endovascular treatment is a trend for traumatic aortic injury because of lower invasivity, morbidity and mortality. We reported a rare case of traumatic aortic injury with thoracic aortic pseudoaneurysm definitively diagnosed by the reconstructional computed tomographic angiography of aorta and successfully treated with endovascular stent-graft.

Giant aortic root pseudoaneurysm surrounding the left main coronary artery.

Project description:A 69-year-old patient underwent an urgent aortic valve replacement because of Streptococcus agalactiae endocarditis of his native aortic valve. Since a rapid progression of the former abscess cavity into an aortic root pseudoaneurysm with increasing paravalvular regurgitation during postoperative follow-up, reoperation was performed. In the preoperative transesophageal echocardiography (TEE) images the pseudoaneurysm completely surrounds the left coronary artery (LCA) without any signs of myocardial ischemia.
