Pseudoaneurysm of the mitral-aortic intervalvular fibrosa with fistulous communication to the left atrium causing congestive heart failure.

ABSTRACT: Pseudoaneurysms of the mitral-aortic intervalvular fibrosa can rupture and form fistulous communications between the left ventricle and left atrium. Pulmonary venous systolic flow reversal in such cases reflects elevated left atrial pressure due to shunting. This finding, particularly in the setting of endocarditis, is not specific for severe mitral regurgitation.

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.

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.).

Pseudoaneurysm of the mitral-aortic intervalvular fibrosa as a complication after minimally invasive mitral valve repair.

Project description:Pseudoaneurysm of the mitral-aortic intervalvular body is a rare condition, which has been reported as a result of endocarditis, chest trauma or cardiac surgery. We describe here the first case after minimally invasive mitral valve repair. Such a complication may be overlooked in the early postoperative echocardiographic study and may lead to fistula formation, compression of adjacent structures, infection, or rupture. Both computed tomography and echocardiography provide a detailed anatomy of the pseudoaneurysm and its communication with the left ventricular outflow tract.

Pseudoaneurysm of mitral-aortic intervalvular fibrosa in a child: Demonstration by MDCT and MRI.

Project description:Subaortic left ventricular outflow tract pseudoaneurysms are rare lesions that are associated with aortic valve diseases, infective endocarditis, trauma or surgery. We present dynamic multidetector computerized tomography and cine magnetic resonance imaging features of a case of subaortic aneurysm arising from interaortic-mitral valvular region in a child with past history of infective endocarditis.

A 16-Year Natural History of a Congenital Pseudoaneurysm of the Mitral-Aortic Intervalvular Fibrosa

Project description:Pseudoaneurysm of the mitral aortic intervalvular fibrosa is a rare condition most often reported as sequela of endocarditis and surgical trauma, with congenital cases being very uncommon. This case describes a congenital pseudoaneurysm of the mitral aortic intervalvular fibrosa and stable 16-year natural history. (Level of Difficulty: Intermediate.) Central Illustration

Pseudoaneurysm of the mitral-aortic intervalvular fibrosa: a rare case after percutaneous transluminal coronary angioplasty.

Project description:BackgroundPseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) is an uncommon but potentially life-threatening condition. The most common pathogenic factors of P-MAIVF are infective endocarditis and surgical valve operation. Here, we report a rare case of P-MAIVF which occurred one year after percutaneous transluminal coronary angioplasty (PTCA).Case presentationA 31-year-old man developed a P-MAIVF one year after PTCA. Transthoracic echocardiography (TTE) revealed a pseudoaneurysm between the aortic root and the left atrium. Three-dimensional transesophageal echocardiography (3D-TEE) clearly demonstrated the orifice of the pseudoaneurysm. This case was initially diagnosed by ultrasound, and the prognosis was good after surgical repair.ConclusionsWe report a rare case of P-MAIVF that occurred one year after PTCA.
