OBJECTIVE: Patients with type II diabetes (T2DM) are at 2-3 fold excess risk of heart failure. Its prevention and treatment are poor. Here we tested the hypothesis that spironolactone, perhaps by limiting myocardial fibrosis, and inorganic nitrate, which acutely affects myocardial dynamics, would improve cardiac structure and function beyond effects of blood pressure (BP) in these patients. DESIGN AND METHOD: 104 patients with or at risk of T2DM participated in a factorial design, double blind, randomised controlled trial (VaSera)...

REVIEW
Ray W Shepherd
PURPOSE OF REVIEW: Peripheral pulmonary lesions (PPL) are being diagnosed with increasing frequency, especially with the increased use of chest computed tomography (CT). Depending on the location and size, these lesions often present a diagnostic challenge in terms of the low yield of traditional bronchoscopic biopsy techniques or the risks of a percutaneous biopsy approach. RECENT FINDINGS: Over the last several years, several different image-guided bronchoscopy techniques have emerged, including virtual bronchoscopic navigation, electromagnetic navigation bronchoscopy, radial endobronchial ultrasound, and ultrathin bronchoscopy...

BACKGROUND AND OBJECTIVES: Compared with the thoracic and lumbar spine, transforaminal epidural injections and medial branch blocks in the cervical spine are associated with a higher incidence of neurological complications. Accidental breach of small periforaminal arteries has been implicated in many instances. In this observational study, using ultrasonography, we surveyed the incidence of periforaminal bloods vessels in the cervical spine. METHODS: Patients undergoing ultrasound-guided cervical medial branch blocks were scanned using color power and pulsed wave Doppler...

Accumulating evidence suggests that nonalcoholic fatty liver disease (NAFLD) is associated with left ventricular diastolic dysfunction (LVDD) in nondiabetic individuals. To date, there are very limited data on this topic in patients with type 2 diabetes and it remains uncertain whether NAFLD is independently associated with the presence of LVDD in this patient population. We performed a liver ultrasonography and trans-thoracic echocardiography (with speckle-tracking strain analysis) in 222 (156 men and 66 women) consecutive type 2 diabetic outpatients with no previous history of ischemic heart disease, chronic heart failure, valvular diseases and known hepatic diseases...

INTRODUCTION: Several studies have shown that the number of B-lines was related to the amount of extravascular lung water (EVLW). In our study, we aimed to demonstrate the magnitude of the incremental B-lines in shock patients with positive net fluid balance and the association with gas exchange impairment. MATERIALS AND METHODS: We performed trans-thoracic ultrasound at admission (T0) and at follow-up period (TFL) to demonstrate the change of B lines (ΔB-lines) after fluid therapy...

Trans-thoracic echocardiography (TTE) is an important non-invasive cardiac examination that provides structural and functional information. It is useful in the diagnosis of cardiac diseases and often guides the management and follow-up of patients with cardiovascular diseases (CVD). The study aimed to present an audit of the echocardiograms performed in an urban private hospital over a two-year period in order to define the pattern of cardiac diseases in our center. Echocardiogram reports of 168 consecutive patients performed between May 2011 and April 2013 at an organized private sector hospital in Lagos, south-west Nigeria were reviewed...

Emerging clinical data support the notion that RV dysfunction is critical to the pathogenesis of cardiovascular disease and heart failure(1-3). Moreover, the RV is significantly affected in pulmonary diseases such as pulmonary artery hypertension (PAH). In addition, the RV is remarkably sensitive to cardiac pathologies, including left ventricular (LV) dysfunction, valvular disease or RV infarction(4). To understand the role of RV in the pathogenesis of cardiac diseases, a reliable and noninvasive method to access the RV structurally and functionally is essential...

The cardiorenal syndrome (CRS) indicates how close the relationship is between heart and kidney during failure of these organs. At present, the classification of the syndrome includes five types of CRS: types I and II which are strictly related to initial heart failure (both acute and chronic), types III and IV which include initial kidney failure, and type V which includes several systemic diseases. Many pathophysiological pathways have been described illustrating how heart and kidney disease are involved in clinical conditions...

PURPOSE: Thoracic pulse wave velocity (PWV) variation due to modulated trans-mural pressure (TMP) may indicate mechanical properties of the aorta. Our aim was to measure beat-to-beat thoracic PWV and TMP to observe its normal variation during respiratory maneuvers. METHODS: We validated PWV measurements from a real-time velocity projection MRI scan in a pulsatile phantom. A volunteer study showed inter-scan repeatability of steady-state PWV, and observed PWV variation when performing Mueller and Valsalva maneuvers...

BACKGROUND: Point-of-care ultrasound (POC-US) use is increasingly common as equipment costs decrease and availability increases. Despite the utility of POC-US in trained hands, there are many situations wherein patients could benefit from the added safety of POC-US guidance, yet trained users are unavailable. We therefore hypothesized that currently available and economic 'off-the-shelf' technologies could facilitate remote mentoring of a nurse practitioner (NP) to assess for recurrent pneumothoraces (PTXs) after chest tube removal...

In this case report, we present an 86-year old patient with an intercostal pseudoaneurysm after transaortic transcatheter aortic valve implantation (TAVI). This new technique of a transaortic approach is considered a possible alternative to the more usual transfemoral, trans-subclavian or transapical access site, mainly in patients with extensive peripheral arterial disease. A mini-thoracotomy or mini-sternotomy is needed to access the ascending aorta. The patient presented with a painless but progressive pulsatile mass right parasternally, 3 months after the procedure...

REVIEW
M Gonzalez, H-B Ris, T Krueger, P-Y Jayet
The discovery of an anterior mediastinal mass requires careful management with specific consideration of the pathology. More than 50% of all mediastinal masses seen in adults are in the anterior mediastinum. The most frequent diagnoses are thymoma, lymphoma, teratoma and benign thyroid tumours. 60% of cases are malignant. Often the clinical and radiological findings do not allow a definitive diagnosis and a histological diagnosis is often required to select the optimal treatment modality. The choice of biopsy technique depends on the localization of the lesion, clinical factors, and the availability of special techniques and equipment...
