Comparative StudyThree-dimensional transoesophageal echocardiography for cardiac output in critically ill patients: A pilot study of ultrasound versus the thermodilution method.
Three-dimensional transoesophageal echocardiography (3D-TOE) is a new noninvasive tool for quantitative assessment of left ventricular (LV) volumes and ejection fraction. ⋯ Noninvasive estimation of CO by 3D-TOE is feasible in ICU patients. This new semi-automated modality is an additional promising tool for noninvasive haemodynamic assessment of ICU patients. However, the wide limits of agreement with thermodilution observed in this pilot study require further investigation in larger cohorts of patients.

Initial experience with the WATCHMAN™ left atrial appendage system for stroke prevention in atrial fibrillation: A single-centre registry.
Left atrial appendage (LAA) closure using the WATCHMAN™ device (WM) may be considered in patients with non-valvular atrial fibrillation (AF) and a high-risk of stroke who are ineligible for long-term oral anticoagulation (OAC). ⋯ When performed by an operator trained in the procedure, WM implantation appears to be safe and effective. This procedure may be considered in patients at high-risk of stroke who are ineligible for long-term OAC.

Localization of gaps during redo ablations of paroxysmal atrial fibrillation: Preferential patterns depending on the choice of cryoballoon ablation or radiofrequency ablation for the initial procedure.
Pulmonary vein (PV) isolation, using cryoballoon or radiofrequency ablation, is the cornerstone therapy for symptomatic paroxysmal atrial fibrillation (AF) refractory to antiarrhythmic drugs. One-third of the patients have recurrences, mainly due to PV reconnections. ⋯ During redo procedures, gap localization pattern is different for patients first ablated with cryoballoon or radiofrequency ablation, and right superior PV reconnections occur more frequently after radiofrequency ablation. Redo ablation of a previous cryoballoon ablation appears to be easier.

Comparison of prognoses of Staphylococcus aureus left-sided prosthetic endocarditis and prosthetic endocarditis caused by other pathogens.
Staphylococcus aureus prosthetic valve endocarditis (SAPIE) is a serious disease. ⋯ SAPIE is a very serious disease, with elevated in-hospital mortality resulting from sepsis-induced multiple organ dysfunction syndrome. Emergency surgery is recommended in these cases, when possible, before the occurrence of complications, especially severe sepsis.

Trends over the past 4 years in population characteristics, 30-day outcomes and 1-year survival in patients treated with transcatheter aortic valve implantation.
Transcatheter aortic valve implantation (TAVI) is recommended in patients with severe aortic stenosis that is either inoperable or at high-risk for surgical valve replacement. ⋯ Over the past 4 years, TAVI has been increasingly performed using a transfemoral approach. Treated patients are at lower-risk with less co-morbidity. Thirty-day mortality and complications remained unchanged, but length of stay after TAVI and 1-year mortality decreased dramatically.
