INTRODUCTION: The Bentall procedure is a cardiac surgery involving graft replacement of the aortic valve, aortic root and ascending aorta. Graft infection after Bentall's procedure (BGI) is infrequent but severe, and often difficult to diagnose and treat. PATIENTS AND METHODS: A retrospective cohort study was performed using the Bordeaux endocarditis database of adult patients admitted to the Bordeaux University Medical Hospital for BGI between 2008 and 2014. Published case reports were identified in the literature...

Hypovolemia is known to be a predisposing factor of decompression illness (DCI) while diving. The typical clinically impressive neurological symptoms of DCI may distract from other symptoms such as an incipient hypovolemic shock. We report the case of a 61-year-old male Caucasian, who presented with an increasing central and peripheral neural failure syndrome and massive hypovolemia after two risky dives. Computed tomography (CT) scans of the chest and Magnetic resonance imaging scans of the head revealed multiple cerebral and pulmonary thromboembolisms...

While the etiology of ischemic stroke is heterogeneous, approximately 20%-40% of all stroke cases result from cardiac or aortic origin. Transesophageal echocardiography (TEE) has become the reference standard modality for the detection of potential sources of cerebral embolism. Because of the advances in computed tomographic (CT) technology, cardiac CT can be used in the evaluation of potential cardioembolic sources. During the past decade, cardiac CT has been tested and compared with TEE for the diagnosis of cardioembolic sources...

AIMS: Evaluation of eccentric mitral regurgitation (MR) remains extremely difficult and the role played by its etiology, functional or degenerative, is not well understood. This study aimed to demonstrate the value of three-dimensional transesophageal echocardiography (3DTEE) in the evaluation of eccentric MR identifying geometric differences in the vena contracta area between functional and degenerative etiologies. METHODS AND RESULTS: We studied 61 patients with eccentric MR (30 functional and 31 degenerative)...

Acute aortic dissection is rare among young patients in the absence of connective tissue disorders. One of the risk factors associated with aortic dissection among young patients is amphetamine use. We report a case of a 37-year-old female with a past medical history of hypertension presenting with syncope and altered mental status who was found to have an acute DeBakey Type I aortic dissection after ingestion of 3,4-methylenedioxymethamphetamine (MDMA), commonly known as ecstasy. This is the second case in the literature describing aortic dissection in relation to MDMA use...

An 84-year-old man presented 5 years following bioprosthetic mitral valve replacement with three months of worsening dyspnea on exertion. A new mitral stenosis murmur was noted on physical examination, and an electrocardiogram revealed newly recognized atrial fibrillation. Severe mitral stenosis (mean gradient = 13 mmHg) was confirmed by transthoracic echocardiography. Transesophageal echocardiography revealed markedly thickened mitral bioprosthetic leaflets with limited mobility, and a massive left atrial thrombus (> 4 cm in diameter) (see Figures 1A-D, and video files 1-4)...

Contrast echocardiography using agitated saline injected into the antecubital vein is the most common method used for the diagnosis of patent foramen ovale. We describe a case whereby the presence of a persistent eustachian valve and a "negative contrast sign" during contrast transesophageal echocardiography raised suspicion of a false-negative result. Femoral vein injection of contrast successfully demonstrated a patent foramen ovale. Femoral vein injection should be considered if this scenario is recognized because the eustachian valve directs blood preferentially from the inferior vena cava toward the interatrial septum and this route may prove to be more reliable...

BACKGROUND AND PURPOSE: Up to 50% of ischaemic strokes in young adults are classified as cryptogenic despite extensive work-up. We sought to evaluate the prevalence of non-obstructive carotid atherosclerosis (NOCA) and its association with patent foramen ovale (PFO) in young adults with cryptogenic stroke (CS). METHODS: Patients aged 18-54 years, consecutively treated for first-ever CS in an academic stroke service, were included. NOCA was assessed using carotid ultrasound examination and was defined as carotid plaque with <50% stenosis...

BACKGROUND: Left atrial appendage flow velocity (LAAFV) and presence of spontaneous echo contrast (SEC) have been reported to be predictors of thromboembolism in atrial fibrillation (AF) patients. Galectin-3 is a biomarker reflecting pro-inflammatory status, whose role in AF has recently drawn attention, particularly in persistent AF population. AIM: In this study we aimed to investigate the association between serum galectin-3 levels and echocardiographic predictors of thromboembolism in persistent AF patients...

Dyspnea and hypoxemia are common postoperative problems after pneumonectomy. One of the rarer causes of respiratory distress after right pneumonectomy is the development of a significant right-to-left shunt across a patent foramen ovale (PFO), which can evolve at a variable interval of time after the operation. We report here our experience with a patient who underwent right pneumonectomy, followed by several complications, and who presented severe dyspnea 7 months later, after the closure of a right thoracostomy...

A 50-year-old man was admitted with fever and chill sensation 6 months ago. Transthoracic echocardiography (TTE) showed left and right coronary cusp prolapses and a thickened tissue of the aortic curtain. Congestive heart failure due to active infective aortic valve endocarditis was diagnosed, and he underwent aortic valve replacement. The aortic annulus was reconstructed using a glutaraldehydetreated autologous pericardium. Six months after surgery, TTE showed severe aortic regurgitation and saccular change in the aortic annulus...

BACKGROUND: Mitral valve repair (MVr) in rheumatic heart disease (RHD) remains challenging. The present authors' surgical experience of MVr in 56 patients with RHD operated in between January 2011 and September 2014 is reported. METHODS: Among the patients (mean age 32 ± 11 years), 11 were in NYHA functional class II, 32 in class III, and seven in class IV. An adequate or oversized autologous pericardial patch was sutured to extend the coaptating edge of both the anterior leaflet (in 18 patients) and the posterior leaflet (in 30 patients)...

Atrial fibrillation (AF) is a major cause of stroke. The restoration of sinus rhythm through cardioversion, either chemical or electrical is a common practice. Interestingly, there is an incremental increase from the baseline risk for embolisation in the immediate post-cardioversion period, with most events occurring within 10 days from cardioversion. Especially patients with recent onset AF show the lowest rates of antithrombotic therapy, while having a high stroke risk. Despite the increased risk for embolisation, anticoagulation in patients undergoing cardioversion of atrial fibrillation is often inadequate...

Atrial fibrillation (AF) is well known for being a major risk factor of thromboembolic stroke. We could recently demonstrate an association of monocyte-platelet aggregates (MPAs) with the degree of thrombogenicity in patients with AF. This study investigated platelet activation markers, as potential biomarkers for the presence of left atrial (LA) thrombus in patients with AF. One hundred and eight patients with symptomatic AF underwent transesophageal echocardiography (TEE) before scheduled cardioversion or pulmonary vein isolation...

Asymmetric dimethylarginine (ADMA) and L-homoarginine (hArg) are L-arginine (Arg) metabolites derived from different pathways. Protein arginine N-methyltransferase (PRMT) and subsequent proteolysis of proteins containing methylarginine residues release ADMA. Arginine:glycine amidinotransferase (AGAT) converts Arg to hArg and guanidinoacetate (GAA). While high concentrations of ADMA and low concentrations of hArg in the blood have been established as cardiovascular risk markers, the cardiovascular relevance of GAA is still unexplored...
