A giant left ventricular pseudoaneurysm diagnosed after double-valve replacement

A diagnostic coronary catheter injury to the subaortic region in a 41-year-old woman with rheumatic heart disease led to a pseudoaneurysm that later caused extrinsic left coronary compression. She subsequently underwent double-valve replacement, overlooking the pseudoaneurysm that enlarged to a giant size three months later following thrombolysis for mitral prosthesis thrombosis. A thrombolysis-induced large intracerebral hemorrhage posed a significant risk for reoperation, and mechanical prosthetic valves in the aortic and mitral positions allowed a catheter option only, through percutaneous transapical access. Interventional closure of the pseudoaneurysm is discussed in this unique report.

Giant left ventricular outflow tract pseudoaneurysm presenting as anterior mediastinal mass: diagnosis by MDCT

We report a case of giant left ventricular outflow tract pseudoaneurysm diagnosed by multidetector computed tomography cardiac angiography. This report highlights the importance of preoperative computed tomography in the evaluation of left ventricular outflow tract pseudoaneurysm which can be kept as a differential diagnosis for anterior mediastinal masses.

Current role of cardiac imaging to guide surgical correction of a giant left ventricular pseudoaneurysm

Article history: Received 25 June 2015 Accepted 27 June 2015 Available online 2 July 2015 showed no significant pericardial effusion. With the suspicious of a mechanical complication after STEMI, a cardiac magnetic resonance (cMR) was performed, confirming the presence of cardiac rupture located in the infero-lateral wall of the left ventricle evolving to a small Ps. The case was discussed at the heart-team meeting and, as the patient remained stable for days, surgery was initially declined. Our patient was subsequently discharged and referred to be

Giant Left Ventricular Pseudoaneurysm after Acute Myocardial Infarction Secondary to Cocaine Use

The patient is a 19-year-old male that reported a 7-year history of regular cocaine presenting at this moment with dyspnea after moderate exertion, orthopnea and paroxysmal nocturnal dyspnea for 30 days. The echocardiogram and the cardiac magnetic resonance imaging showed a giant left ventricle pseudoaneurysm secondary to the usage of cocaine and previous myocardial infarction. The combination of these situations made this patient a unique case. We showed that the surgical treatment may be an option.

A case of a giant left ventricular pseudoaneurysm

Cardiac pseudoaneurysm is a rare but potentially lethal complication of myocardial infarction. Clinical manifestations may be nonspecific or, in some cases, may even be silent. Therefore, high clinical suspicion should be maintained when a patient becomes unstable after a myocardial event. Efficient use of imaging examinations is crucial in providing an accurate diagnosis and, thereafter, timely and appropriate treatment. The authors report a case involving a giant left ventricular pseudoaneurysm that required both transthoracic echocardiography and magnetic resonance imaging to reach the correct diagnosis. The pathology, clinical presentation, diagnostic work-up and treatments of cardiac pseudoaneurysms are reviewed.

Giant Left Ventricular Pseudoaneurysm as a Complication After Mitral Valve Replacement Surgery

57-year-oldwomanpresentedwith seizure, exertional Ashortness of breath (New York Heart Association Class III) and angina-like chest pain. Her cardiac history revealed successful bioprostheticmitral valve replacement for endocarditis 1 year prior. Chest radiography detected a 9-cm mass overlying the left hilum with an incomplete right border (Fig 1A, arrows). On transthoracic echocardiography, there was a communication from the posterior mitral valve annulus with an apparent left ventricular (LV) pseudoaneurysm (PSA) measuring approximately 51 52 mm (Fig 1B). Visualized valves showed thickening of the mitral valve leaflets with adjacent high-density

A ballooning heart-giant left ventricular apical pseudoaneurysm presenting as congestive heart failure

Left ventricular (LV) pseudo aneurysm is a contained rupture of ventricular wall by adherent pericardium or scar tissue. We present a case of a 70 year-old male presented with exertional dyspnea for 2 months and found to have giant LV pseudo aneurysm on transthoracic echocardiogram, cardiac MRI and angiogram. To our knowledge such a large pseudo aneurysm involving LV apex and presenting as congestive heart failure is the first case in literature.

Giant left ventricular pseudoaneurysm following inferior wall myocardial infarction—A case report

Giant left ventricular pseudoaneurysm following an inferior wall myocardial infarction (MI) is a rare complication occurring in 0.1 % of cases but is associated with 50 % mortality (Hoey et al. J Emerg Med 28:431–5, 2005). It develops when the Left Ventricular (LV) free wall ruptures following a transmural Myocardial Infarction (MI) and is contained by the adherent pericardium or scar tissue. We describe the management of a patient who had suffered a recent undiagnosed inferior wall MI and then developed a giant left ventricular pseudoaneurysm.

A giant left ventricular pseudoaneurysm in Behçet's disease: a case report

Behçet's disease is a chronic autoimmune disease with vascular complications that are most frequently manifested as thromboembolism in veins and pseudoaneurysm in arteries. We report the case of a 13-year-old boy admitted for clinical and biological signs of rheumatic fever associated with chest pain. The clinical examination found heart sounds with a discrete systolic murmur of mitral regurgitation. The electrocardiogram showed a microvoltage with diffuse repolarisation disorder. Biologically, he had inflammatory syndrome. Transthoracic echocardiography showed circumferential pericardial effusion with anterosepto-apical hypokinesia of the left ventricle with systolic dysfunction, and a minimal mitral regurgitation. The patient was treated by corticotherapy and antibiotherapy. The outcome was marked by orogenital aphthous ulceration and decreased visual acuity related to intermediate uveitis. The retinal angiography showed a vasculitis. The late appearance of this symptom led to the right diagnosis of Behçet's syndrome. Transthoracic echocardiography showed a hypokinetic dilated cardiomyopathy left ventricular with septo apical and anterior akinesia and severe systolic dysfunction, with a defect of the inferior septal with a collar communicating the left ventricle with a giant pseudo aneurysm. Magnetic resonance imaging showed a giant pseudoaneurysm communicating with the left ventricle. The coronary computed tomography was normal. The patient had undergone surgical treatment for the pseudoaneurysm with good outcomes.

Surgical approach to giant pseudoaneurysm of the left ventricle

Left ventricular pseudoaneurysm is a rare, but lifethreatening complication occurring after acute myocardial infarction. Early diagnosis and surgery are critical for the patients’ recovery. An 80-year-old man was admitted to hospital with severe dyspnea. Coronary angiography and ventriculography showed a giant left ventricular pseudoaneurysm. Surgical approach to pseudoaneurysm was made through the mitral valve and directly from the aneurysmal sac. Defect was closed by Dacron patch. Postoperative period was uneventful and patient was discharged from hospital seven days after surgery.

Left ventricular pseudoaneurysm after surgery for infective endocarditis

A 46-year-old man had undergone aortic valve replacement for aortic regurgitation due to active infective endocarditis in 2006. He had been followed by transthoracic echocardiography revealing results within normal limits except for a subannular depressed scar. In 2010, a giant left ventricular pseudoaneurysm was detected on three-dimensional computed tomography. We performed surgery for patch closure of the pseudoaneurysm and redo aortic valve replacement.

Giant unruptured left ventricular pseudoaneurysm as a rare cause of heart failure after an unnoticed coronary ischaemic event

A 47-year-old male with a history of hypertension and smoking habit, but no known ischaemic heart disease was referred for a study of dyspnoea and asthenia in the last year. EKG ( Panel A ) showed ST elevation and Q waves in the inferior leads. Transthoracic echocardiography (TTE) revealed dilated left chambers ( Panel B ), a left ventricular (LV) ejection fraction of 27% and the presence of a giant LV apical pseudoaneurysm sealed …

An Unusual Case of a Giant Left Ventricular Pseudoaneurysm

Left ventricular pseudoaneurysm is one of the late mechanical complications of myocardial infarction, which also can be associated with cardiothoracic surgery, trauma, and, rarely, infective endocarditis. A giant pseudoaneurysm is a rare presentation. We report a patient with a giant left ventricular pseudoaneurysm probably following a silent myocardial infarction, who presented with congestive heart failure symptoms. Unfortunately, cardiac rupture and tamponade developed during diagnostic studies. The patient had surgical repair of the aneurysm and the mitral valve, but could not recover fully after surgery. We suggest urgent surgery whenever a giant left venricular pseudoaneurysm is diagnosed.

Endoscopic repair for left ventricular pseudoaneurysm with right minithoracotomy

Left ventricular pseudoaneurysm (LVPA) is a known serious complication of myocardial infarction or mitral valve replacement. As an alternative option, transmitral patch repair for LVPA has been reported. However, it is very difficult to complete the procedure for LVPA with a large defect. A 68-year old man with a history of inferior myocardial infarction had undergone mitral valve repair. At 4 months after surgery, the presence of a giant LVPA in the posteroinferior left ventricular wall was revealed. We performed transmitral patch repair through minithoracotomy under a three-dimensional videoscope. Since the intracardiac operation was performed under only camera vision, the perspective supplied by the three-dimensional videoscope was very useful. Endoscopic patch repair was a much less invasive procedure, and we could obtain a great intracardiac view. This technique can be an appropriate option for the treatment of LVPA after cardiac surgery.

Giant left ventricular pseudoaneurysm presenting with hemoptysis

Left ventricular (LV) pseudoaneurysm is a late mechanical complication of myocardial infarction (MI). A giant LV pseudoaneurysm is a rare presentation. We report a case of a giant LV pseudoaneurysm in a post MI patient, who presented with hemoptysis. Hemoptysis is a rare clinical presentation of LV pseudoaneurysm. The patient had successful surgical repair of the aneurysm and had a favorable outcome in 9 mo' follow-up. The imaging modalities and surgical treatment of a pseudoaneurysm is discussed.

Giant left ventricular pseudoaneurysm following coronary artery bypass graft surgery

thrombosed (t), within the inferior pericardial space and the rupture of the left ventricular inferior wall (arrowheads). Figure 2: Late-enhancement T1-weighted (a) and T2-weighted (b) magnetic resonance images confirmed the presence of the pseudoaneurysm (p) with the enhancement of the surrounding thickened pericardial layers (arrowheads) and revealed a trans-mural haemorrhagic inferior myocardial infarction (arrow in a); T2-weighted images demonstrated the presence of oedema in adjacent myocardium (arrow in b), sign of acute re-infarction. A ‘fresh’ thrombus (t) was observed in the right portion of the pseudoaneurysm.

Surgical Treatment of a Giant Postero-Inferior Left Ventricular Pseudoaneurysm Causing Severe Mitral Insufficiency and Congestive Heart Failure

Left ventricular pseudoaneurysm caused by a transmural myocardial infarction is a fatal complication. Reliable diagnosis and on-time surgical intervention are significant for the patient's survival. A 70-year-old diabetic man with a two-month earlier history of successful stent implantation on the proximal right coronary artery because of total occlusion was admitted to our institution with symptoms of congestive heart failure. Transthoracic echocardiogram showed severely decreased overall LV systolic function and a large aneurismal sac attached to the inferior surface of the left ventricle, moderate tricuspid regurgitation and severe mitral insufficiency. On transesophageal echocardiography examination and cardiac magnetic resonance imaging, the aneurismal cavity appeared to be entirely surrounded by thrombi. During the operation, a left ventricular postero-inferior pseudoaneurysm was observed to extend to the mitral annulus. Purse string suturing was used to reduce left ventricular volume, and the hole was closed with a Dacron patch. The patient was weaned from the CPB without any difficulty. The patient's postoperative period was uneventful, and his physical condition appeared to be very healthy (NYHA class I-II) after the first year. Following a myocardial infarction, a careful preoperative examination and proper way to diagnose are essential on patients with nonspecific complains or asymptomatic. Despite the risk of high mortality, patients may survive when they are diagnosed and undergo surgery at the right time.

Successful Resection of a Giant Left Ventricular Pseudoaneurysm Developed Later after Mitral Valve Replacement

We present a case of successful surgical resection of a giant left ventricular (LV) pseudoaneurysm that developed 5 yr after mitral valve replacement (MVR). A 59-yr-old female was admitted with exertional chest pain radiating to left arm and back. 64-slice multidetector computed tomography (MDCT) revealed significant stenosis on the ostium of the first diagonal branch of the left anterior descending coronary artery and also a huge pseudoaneurysm compressing the right atrium and the inferior vena cava. She underwent resection of the pseudoaneurysm, and the pseudoaneurysm tunnel was repaired from the inside of LV cavity by removing the previously inserted prosthetic valve, followed by redo MVR together with coronary arterial bypass grafting (CABG) for a single-vessel disease. At the 6-month follow-up, the patient continued to do well without any complications.

"Mushroom cloud": a giant left ventricular pseudoaneurysm after a myocardial infarction due to myocardial bridging – a case report

Left ventricular pseudoaneurysm is an uncommon complication after transmural myocardial infarction, occurring when a free wall rupture is contained by adhesions of the overlying pericardium preventing acute tamponade. In this report, an unusual case of a 61 year-old male with a giant apical left ventricular pseudoaneurysm after an unnoticed myocardial infarction is presented. On coronary angiogram myocardial bridging of the distal left anterior descending artery was judged to be the infarct related lesion. The echocardiographic diagnosis allowed for a timely surgical intervention which resulted in the patient's full recovery.
