Left ventricular pseudoaneurysm as a complication of prosthetic mitral valve infective endocarditis.

ABSTRACT: We report a case of infective endocarditis complicated with left ventricular pseudoaneurysm originating from the posterior annulus of the prosthetic mitral valve in a 56-year-old woman. Despite prolonged antibiotic treatment, transesophageal echocardiography (TEE) showed partial detachment of the prosthesis from the posterior mitral annulus. Three-dimensional rotational computed tomography clearly demonstrated a pseudoaneurysm toward the posterolateral portion of the mitral prosthetic valve, which was not evident by TEE. Valve replacement and repair of the pseudoaneurysm were performed 83 days after initiation of antibiotic therapy. Left ventricular pseudoaneurysm is a rare but serious complication of mitral prosthetic valve endocarditis. It requires prompt diagnosis and early surgical intervention. .

Cardiac pseudoaneurysm as a complication of native mitral valve infective endocarditis.

Project description:BackgroundThe delayed development of a mitral valve annulus pseudoaneurysm is a rare and late complication of a native mitral abscess cavity.Case summaryCurrently, there are no documented cases of a pseudoaneurysm developing from an abscess cavity of the posterior annulus of the native mitral valve. We report a case of a patient who presented with worsening progressive shortness of breath that was found to be secondary to a pseudoaneurysm. This was detected by 2D echocardiogram and cardiac computed tomography angiography.DiscussionIn our case, the patient developed a late complication of a ventricular pseudoaneurysm originating from the mitral annular area of the abscess cavity. Per the surgical literature, one method to avoid the aforementioned complication is via cavity repair with a bovine patch.

Blood in, blood out: left ventricular pseudoaneurysm following mitral valve endocarditis.

Project description:A 76-year old male on warfarin due to atrial fibrillation was admitted with Staphylococcus aureus septicaemia. Echocardiography demonstrated mitral valve endocarditis, and shortly thereafter, he suffered an intracranial haemorrhage as a result of septic embolism. Four weeks later, cardiac magnetic resonance imaging revealed a newly formed pseudoaneurysm. A left ventricular pseudoaneurysm caused by infective endocarditis is very rare, but awareness of this unusual complication may allow surgery to prevent rupture.

Aorto-right pulmonary venous fistula after mitral valve replacement for prosthetic mitral valve infective endocarditis: a case report.

Project description:BackgroundAorto-cavitary fistula is a rare condition, and the most common underlying aetiology is infective endocarditis (IE) of the native or the prosthetic aortic valve. We report a case of aorto-right inferior pulmonary venous fistula following redo mitral valve replacement (MVR) for prosthetic mitral valve IE.Case summaryA 74-year-old woman underwent urgent redo MVR for prosthetic mitral valve IE. The post-operative course was complicated with heart failure and mediastinal haematoma compressing the left atrium. The haematoma was surgically removed and laceration of the left atrial wall was suture ligated; this was attributed to the surgical trauma dissection of the adhesive tissues. One-week post-operatively, a continuous murmur emerged, which prompted an evaluation of the left to right shunt. Transthoracic echocardiography revealed an echolucent area posterior to the aorta, with continuous flow on colour Doppler. Three-dimensional computed tomography showed a fistula between the aorta and the right inferior pulmonary vein. There was a high risk involved in surgical management; therefore, she was managed medically. Fortunately, the continuous murmur and echolucent space disappeared after 6 months. The fistula was considered to be obstructed by spontaneous thrombus formation in the narrowed segment of the fistula tract.DiscussionThe cause of fistula was attributed to possible surgical trauma in the presence of infection. The present case was unique, as it showed spontaneous healing of an aorto-cavitary fistula, which is very rare. The patient was alive with good health status, 6?years after the MVR.

Left atrial endocarditis as a rare complication of mitral valve endocarditis: a clinical case.

Project description:BackgroundInfective Endocarditis (IE) is considered as a multifaceted problem in every aspect from etiology and presentation to diagnosis and management. Early recognition of this disease and especially its complications, remain a critical task for the cardiologist. Atrial endocarditis is a rare and sometimes unrecognized complication of mitral valve endocarditis.Case presentationWe present a 48 year-old male patient who was admitted to our clinic because of recent onset of malaise, fever, jaundice and peripheral edema. Important physical findings were peripheral stigmata of IE in addition to holosystolic murmur over the left sternal border. Transthoracic and transesophageal echocardiophy revealed a severe eccentric MR due to a flailed posterior mitral valve caused by IE. The presence of atrial septal endocarditis caused by jet streaming was also observed. Blood culture was positive for streptococcus oralis and antibiotic therapy was immediately initiated. Considering the large burden of infective tissue, the patient was planned for an early surgical intervention. A minimally invasive resection of the atrial mass, direct closure of the defect, resection of the diseased portions of mitral leaflets and implantation of a biological mitral valve prosthesis was performed. Intra-operative and histological findings confirmed provisional diagnosis by echocardiography.ConclusionsTogether with comprehensive echocardiographic evaluation, attention should be placed on mural vegetations and excluded among all cases of mitral valve endocarditis, particularly those with severe eccentric regurgitant jets.

Prosthetic mitral valve Aspergillus fumigatus endocarditis.

Project description:Aspergillus endocarditis is a fatal source of valvular infection with a near 100 % mortality rate if pharmacotherapy and valve-replacement surgery are not initiated swiftly after diagnosis. Complicating its diagnosis is the low yield for growth on standard blood culture and time requirements for molecular diagnostic tools to return a result. Aspergillus endocarditis of the mitral valve presents as valvular vegetations that reduce the caliber of the mitral valve and can cause syncope as in the case of mitral stenosis with subsequent valve failure, left atrial enlargement, and prospective cardiovascular failure. Reports of the management of Aspergillus endocarditis after serial mitral valve replacement are not prominent in the literature. We report the case of a 41-year-old female with previous mitral valve prosthesis who received a second prosthetic mitral valve after a syncopal episode. Vegetations resembling thrombi were noted on transesophageal echocardiogram, diagnosed as Aspergillus fumigatus endocarditis, and successfully treated with antifungal therapy in conjunction with removal of her dysfunctional prosthesis.

Internal repair of left ventricular pseudoaneurysm late after mitral valve replacement.

Project description:Late left ventricular pseudoaneurysm is a rare complication after mitral valve replacement. Most investigators have recommended surgical repair to treat left ventricular pseudoaneurysm, since untreated left ventricular pseudoaneurysm have a high risk of rupture. Here, we report a case of a 57-year old man with left ventricular pseudoaneurysm. He had two prior mitral valve replacements 16 and 19 years ago, as well as mitral and aortic valve endocarditis causing mitral valve perivalvular leak and perforation of the aortic valve. The mitral and aortic valves were replaced with bovine pericardial valves. Left ventricular pseudoaneurysm was successfully repaired internally in our case because the internal wall at the level of the left ventricle was very fibrotic and matured.

Project description:We present the case of an adult patient with Kartagener's syndrome, multiple prior sternotomies, and recurrent prosthetic valve endocarditis, a scenario without clear guidelines to direct management. Ultimately, the team elected for medical management given the high mortality risk associated with surgery; the patient responded to antibiotic therapy.

Pseudoaneurysm of the left atrium following infective endocarditis.

Project description:Transthoracic echocardiogram of a 3-year-old child showed a hypoechoic cavity in the posterior wall of the left atrium communicating with the left ventricle through an orifice in the mitral annulus, suggestive of pseudoaneurysm (Ps), probably the result of infective endocarditis. Three-dimensional echocardiography was helpful to confirm the diagnosis and assess the anatomical relationship of the Ps.
