Rapid Occurrence of Giant Left Ventricular Pseudoaneurysm after Mitral Valve Replacement

ECHOCARDIOGRAPHY, Issue 10 2008
Sofiene Rekik M.D.
Left ventricular pseudoaneurysms are an uncommon and frightening complication after mitral valve replacement. We report the case of a 54-year old woman, having undergone a mitral valve replacement with uneventful postoperative course and normal echocardiographic predischarge control, who was readmitted to hospital, only 16 days later, for rapidly progressing dyspnea, and finally echocardiographically diagnosed to have a massive 8-cm long pseudoaneurysm communicating with the left ventricle through a narrow communication. The patient was proposed for emergency surgery but unfortunately died preoperatively. [source]

Real-Time Three-Dimensional Echocardiography in Diagnosis of Right Ventricular Pseudoaneurysm after Pacemaker Implantation

Right ventricular rupture is a critical cardiac complication associated with cardiac tamponade and death. Occasionally, the site of rupture may be contained by the parietal pericardium and thrombus, thus forming a pseudoaneurysm. Cases of traumatic pseudoaneurysm of the right ventricle have been reported. However, right ventricular pseudoaneurysm following pacemaker implantation has not been previously reported. This case demonstrates two right ventricular pseudoaneurysms following perforation of the right ventricular wall using real-time three-dimensional echocardiography (3DE) after pacemaker implantation although only one definite pseudoaneurysm was diagnosed by routine two-dimensional echocardiography (2DE). We also found that color Doppler 3DE enhanced visualization of the connections between the right ventricle and the pseudoaneurysm. Color Doppler 3DE allowed us to peel away the myocardial tissue and rotate the image to study the jets from different angles. In summary, real-time 3DE and color Doppler 3DE provided excellent visualization of the right ventricular pseudoaneurysm, flow between the ventricle and the pseudoaneurysm, and additional information to that obtained by 2DE.

Missed Diagnosis of Unruptured, Huge Left Ventricular Pseudoaneurysm

We report a case of a huge left ventricular pseudoaneurysm following myocardial infarction. Early after myocardial infarction, the pseudoaneurysm was missed during the cardiac examination. The patient underwent coronary bypass surgery with endoaneurysmorraphy of the pseudoaneurysm, and made a satisfactory recovery. (ECHOCARDIOGRAPHY, Volume 20, January 2003) [source]

Left Coronary Artery Arteriovenous Malformation Presenting as a Diastolic Murmur with Exercise Intolerance in a Child with a Suspected Familial Vascular Malformation Syndrome

CONGENITAL HEART DISEASE, Issue 3 2007
Valerie A. Schroeder MD
Abstract Objective., Intracardiac arteriovenous malformations are rare and may be associated with sudden death in adults. This case report describes an intracardiac left coronary arteriovenous malformation in a 7-year-old boy with a suspected familial cutaneous vascular malformation syndrome. The patient presented with a diastolic murmur, exercise intolerance, chest pain, and a left ventricular mass. Methods., The left ventricular mass was initially identified by echocardiography. Subsequently, a computed tomography scan revealed the vascular nature of the lesion. We hypothesized that the lesion represented either an arteriovenous malformation (AVM) or a hemangioma. These lesions are thought to cause coronary steal and myocardial dysfunction. Skin biopsies of the patient's cutaneous lesions revealed capillary hyperplasia, which was not consistent with either hemangioma or AVM. Thus, a surgical biopsy and partial resection of the mass was performed. Results., The surgical pathology of the cardiac mass was consistent with an AVM. Within 6 months following partial resection of the mass, the patient unexpectedly developed a left ventricular pseudoaneurysm at the resection site and required re-operation. Although a portion of the mass remains, both the patient's chest pain and exercise tolerance have improved subjectively. Conclusion., Patients with cutaneous vascular malformations and diastolic murmurs, as well as cardiac symptoms, should undergo echocardiography or alternative imaging modalities to screen for treatable pathological myocardial vascular malformations.

Left Ventricular Pseudoaneurysm Developing as a Late Complication of Coronary Artery Bypass Grafting with Apicoseptal Plication

ECHOCARDIOGRAPHY, Issue 8 2005
Ozcan Ozeke M.D.
Left ventricular pseudoaneurysm is a false aneurysm, which results from a left ventricle rupture contained by adherent pericardium or scar tissue. The most common etiology of left ventricular pseudoaneurysm is acute myocardial infarction but one-third of pseudoaneurysms develop following surgery. We present a case report of a patient who developed a false aneurysm of the left ventricle 2 months following surgical repair of a left ventricular aneurysm with a concomitant coronary bypass.
