OBJECTIVES: Axillary artery cannulation is commonly used in thoracic aortic surgery, often utilizing a sidearm graft. Although our institutional preference is femoral cannulation, we use axillary cannulation in select cases with a 'dirty' aorta on computed tomography scan or intraoperative transoesophageal echocardiography. Since 2011, we have routinely used an open Seldinger-guided approach for axillary cannulation. Here, we report our experience with open Seldinger-guided technique, evaluating its safety and efficacy...

AIMS: Patients with chronic kidney disease (CKD) have an excess of cardiovascular morbidity and mortality, with heart failure (HF) being particularly frequent. Reduced left ventricular ejection fraction (LVEF) defines left ventricular (LV) systolic dysfunction and is associated with poor prognosis. However, CKD patients may have HF symptoms with preserved LVEF. In this subgroup of patients, two-dimensional speckle tracking echocardiography can detect LV systolic dysfunction by analysing LV myocardial deformation...

After myocardial infarction (MI), the heart is difficult to repair because of great loss of cardiomyoctyes and lack of cardiac regeneration. Novel drug candidates that aim at reducing pathological remodeling and stimulating cardiac regeneration are highly desirable. In this study, we identified if and how a novel porcupine inhibitor CGX1321 influenced MI and cardiac regeneration. Permanent ligation of left anterior descending (LAD) coronary artery was performed in mice to induce MI injury. Cardiac function was measured by echocardiography, infarct size was examined by TTC staining...

Functional mitral regurgitation (MR;FMR) is the most common type of MR and its development is associated with increased morbidity and mortality. Leaflet tethering with apical shift of the papillary muscle due to adverse left ventricular remodeling and loss of normal leaflet coaptation is the principal mechanism of FMR. Echocardiography plays a central role in the assessment of the FMR. The development of 3D echocardiography has allowed for assessment of the geometric changes of mitral valve morphology and spatial relationship with the left ventricle that accompanies FMR...

Aims: We hypothesized that the absence of a decrease in minimal left ventricular (LV) pressure during exercise would be associated with impaired LV apical back rotation during exercise. Methods and results: A total of 21 patients (59 ± 10 years) underwent invasive LV pressure measurements and simultaneous echocardiography at rest and during submaximal supine bicycle exercise. Patients were classified according to the changes in minimal LV pressure from rest to maximal exercise (Δminimal LVP); Group 1 (n = 8) had a decrease in minimal LV pressure with exercise, whereas Group 2 (n = 13) had an increase in minimal LV pressure...
