Non-infective endocarditis, also referred to as non-bacterial thrombotic endocarditis, represent a wide range of rare pathologies, often severe. This review gathered the data available in the literature, to decipher the major information collected on the pathophysiology, the diagnosis and the treatment of these heterogeneous diseases, often misdiagnosed. Characteristics of non-infective endocarditis are similar to infective endocarditis in terms of valvular lesions (mostly left-sided, with regurgitations and vegetations), and their complications (embolism)...

BACKGROUND: Isolated right Superior Vena Cava drainage into the left atrium in the absence of other cardiac anomalies is an extremely rare condition. The vein of Galen aneurysmal malformation is a congenital vascular malformation. It comprises 1% of all pediatric congenital anomalies. The association vein of Galen aneurysmal malformation, with congenital heart disease has been described. CASE PRESENTATION: We describe a 16-months old toddler presenting at 7-months of age with respiratory distress and cyanosis...

Our objective is to summarize our experience in the diagnosis and treatment of Lambl's excrescence (LE) on the aortic valve. Methods: The clinical data of 25 patients with LE admitted to our hospital from January 2010 to December 2014 were analyzed retrospectively. There were 17 males and 8 females, with the mean age of 55.7 ± 11.43 years (range: 30 to 70 years). Among the patients analyzed, eight also had cerebral embolism. All of the patients were diagnosed by transesophageal echocardiography (TEE). In seven cases, surgical treatment to remove the excrescence was successfully performed...

BACKGROUND: About one third of ischaemic strokes are classified as embolic strokes of undetermined source (ESUS). A silent atrial fibrillation (AF) may play a pathogenic role in these strokes and P wave dispersion (PWD), representing an electrocardiographic (ECG) predictor for paroxysmal AF, thereby a potential marker of covert cardioembolism, was found to be increased in cryptogenic stroke. Furthermore, current evidence links AF to inflammation: inflammatory markers, such as high-sensitive C-reactive protein (hsCRP), have been related to the development and persistence of AF, possibly by promoting atrial remodelling...

True ventricular aneurysm is a scarred wall that most commonly results after an unrevascularized ST elevation myocardial infarction. Patients usually present with heart failure, angina, ventricular arrhythmia, systemic embolization, or ventricular rupture. Diagnosis can be achieved via echocardiography, left ventricle angiogram, cardiac computed tomography, or cardiac magnetic resonance.

A 41-year-old woman was visiting Oxford, where she had a sudden cardiac arrest. Cardiopulmonary resuscitation was started by a bystander until the paramedics arrived, who found her in ventricular fibrillation, and delivered three shocks. After 28 min she had return of spontaneous circulation. Emergency coronary angiography revealed normal coronary arteries. Echocardiography followed by a cardiac MRI showed non-dilated left ventricles with no evidence of late gadolinium enhancement. She had a single-chamber implantable-cardioverter defibrillator (ICD)...

Pulmonary hypertension (PH) in adults with sickle cell disease (SCD) is associated with early mortality. Chronic thromboembolic pulmonary hypertension (CTEPH) is an important complication and contributor to PH in SCD, but likely underappreciated. Guidelines recommend ventilation-perfusion scintigraphy (V/Q) as imaging modality of choice to exclude CTEPH. Data on V/Q are limited in SCD. Objective: To compare the performance of V/Q with computed tomography pulmonary angiography (CTPA) and to report clinical outcomes associated with abnormal V/Q...

A 54-year-old Caucasian woman presented with an episode of loss of consciousness and dysphasia. MRI revealed a number of ischaemic foci indicating an embolic source. Echocardiography showed a mitral valve vegetation. After taking three sets of blood cultures, she was started on empirical treatment for infective endocarditis. The blood cultures remained negative and a presumed diagnosis of culture-negative endocarditis was entertained. However, despite the antibiotic therapy, the patient deteriorated further...

BACKGROUND: Cardiac chambers' sizes were previously studied by echocardiography, among patients with progressive kidney disease only. We aimed to explore the relations between all heart chambers' volumes as assessed by CT pulmonary angiography and renal function - throughout all ranges. METHODS: Using a novel technology of automatic four chamber volumetric analysis, we analyzed CT pulmonary angiographies of 744 consecutive patients (between January 1st and December 31st , 2014) without pulmonary embolism, and correlated the chambers' volumes indexed to body surface area, to the estimated glomerular filtration rates...

INTRODUCTION: Pulmonary embolism (PE) presents with complex clinical manifestations ranging from asymptomatic to chest pain, hemoptysis, syncope, shock, or sudden death. To the authors' knowledge, itinerant chest pain has not been reported as sign or symptom of PE. CASE PRESENTATION: A 41-year-old woman presenting with left chest pain, no hemoptysis, or breathing difficulties. The chest pain was more severe on deep inspiration. Chest computed tomography (CT) and ultrasound imaging showed left pleural effusion...

A 59-year-old woman presented with a sudden onset of breathlessness and chest pain. An echocardiography and CT scan showed pulmonary embolism and infarction with a paradoxical thrombus visualised in both atria. For haemodynamically stable patients, the optimal management strategy is poorly defined. Three main strategies were considered: surgical thrombectomy, thrombolysis and anticoagulation. Surgery with reversal of anticoagulation may lead to further coagulation and increased risk of bleeding complications...

We established a rabbit model of acute massive pulmonary embolism with associated circulatory shock using autologous blood clots. Rabbits were randomly divided into sham operation group (S group), model group (M group, equal volume of saline, i.v. after shock), and sodium nitroprusside group (SNP group, sodium nitroprusside, i.v. after shock). SNP treatment significantly decreased mean pulmonary arterial pressure and increased mean arterial pressure and arterial partial pressure of oxygen (PaO2 ) and resulted in a partial reversal of the acute circulatory failure...

The appearance of right-sided mural infective endocarditis has rarely been reported. Here, we report the case of a 40-year-old male with a history of alcoholic liver disease who presented with a partial loss of consciousness and fever. Chest computed tomography scans showed multiple pulmonary infiltration sites and cavities. A repeat transthoracic echocardiogram detected a vegetation on the right ventricular surface of the interventricular septum middle segment, as well as pericardial effusion. Blood, pericardial fluid, sputum, and scalp effusion cultures were positive for methicillin-sensitive Staphylococcus aureus...

BACKGROUND: An anomalous muscle bundle crossing the right atrial cavity represents a pathological finding with unproved clinical significance. This congenital anomaly may be difficult to recognize via echocardiography and could be confused with other intra-cavitary lesions. METHODS: We report a case of a 53-year-old female presented to the cardio-vascular service with acute superior vena cava syndrome and sub-massive pulmonary embolism. RESULTS: The patient underwent venography confirming superior vena cava stenosis...

INTRODUCTION: Cardiac hydatid disease is uncommon and occurs in 0.5 to 2% of patients with hydatidosis. Isolated intrapericardial hydatid cystic disease is extremely rare. OBSERVATION: We report the case of a young woman with cardiac compression due to multiple primary intrapericardial hydatid cysts. Since 1 year, she had gradual general health deterioration including dyspnoea, sweats and weight loss of 8kg. A widening of the mediastinum was observed on chest X-ray...

Optimal risk stratification is essential in managing patients with an acute pulmonary embolism (PE). There are limited data evaluating the potential additive value of various methods of evaluation of right ventricular (RV) strain in PE. We retrospectively evaluated RV strain by computed tomography (CT), transthoracic echocardiography (TTE), electrocardiography (ECG), and troponin levels in consecutive hospitalized patients with acute PE (May 2007 to December 2014). Four-hundred and seventy-seven patients met inclusion criteria...

Hafiz B Mahboob, Bruce W Denney
Massive pulmonary embolism (PE) frequently leads to cardiac arrest (CA) which carries an extremely high mortality rate. Although available, randomized trials have not shown survival benefits from thrombolytic use. Thrombolytics however have been used successfully during resuscitation in clinical practice in multiple case reports and in retrospective studies. Recent resuscitation guidelines recommend using alteplase for PE related CA; however they do not offer a standardized treatment regimen. The most consistently applied approach is an intravenous bolus of 50 mg tissue plasminogen activator (t-PA) early during cardiopulmonary resuscitation (CPR)...
