To evaluate whether right ventriculo-arterial coupling obtained by the estimation of the two-dimensional right ventricular (RV) longitudinal strain and of the pulmonary arterial systolic pressure (PASP) could improve prognostic stratification of chronic heart failure (CHF) outpatients. ⋯ Indexing RV function, assessed by speckle-tracking analysis, with an estimation of pulmonary systolic arterial pressure provides a parameter of ventricular arterial coupling that is independently associated with an increased risk of mortality.

Evaluating microcirculatory function in severely ill neonates is a relevant, unmet clinical need. Inappropriate peripheral microvascular vasodilatation is thought to contribute to cardiovascular alterations in preterm infants with acute respiratory distress syndrome (ARDS). We directly evaluated microcirculatory function in preterms with ARDS. ⋯ We demonstrate that it is possible to assess, non-invasively and quantitatively, vasodilator response of skin microcirculation to physiological stimuli in neonates. We also documented that microvascular vasodilation is impaired in preterms with ARDS.

Observational Study
Cardiopulmonary resuscitation of out-of-hospital traumatic cardiac arrest in Qatar: A nationwide population-based study.
Traumatic cardiac arrest studies have reported improved survival rates recently, ranging from 1.7-7.5%. This population-based nationwide study aims to describe the epidemiology, interventions and outcomes, and determine predictors of survival from out-of-hospital traumatic cardiac arrest (OHTCA) in Qatar. ⋯ The incidence of OHTCA was less than expected, with a low rate of survival. Thoracotomy was not associated with improved survival while Adrenaline administration lowered survival in OHTCA patients with majority blunt injuries. Interventions to enable early prehospital control of hemorrhage, blood transfusion, thoracostomy and surgery improved survival.

Review Meta Analysis
Aortic stenosis and non-cardiac surgery: A systematic review and meta-analysis.
Aortic stenosis (AS) poses a perioperative management dilemma to physicians looking after patients who require non-cardiac surgery. The objective of this review is to investigate mortality and adverse cardiovascular events in patients with and without AS who underwent non-cardiac surgery. ⋯ Patients with AS undergoing non-cardiac surgery have not been shown to be at increased risk of mortality, but have significantly higher rates of adverse cardiovascular events compared to patients without AS.

Meta Analysis Comparative Study
Tricuspid annuloplasty versus a conservative approach in patients with functional tricuspid regurgitation undergoing left-sided heart valve surgery: A study-level meta-analysis.
Tricuspid valve (TV) repair at the time of left-sided valve surgery is indicated in patients with either severe functional tricuspid regurgitation (TR) or mild-to-moderate TR with coexistent tricuspid annular dilation or right heart failure. We assessed the benefits of a concomitant TV repair strategy during left-sided surgical valve interventions, focusing on mortality and echocardiographic TR-related outcomes. ⋯ A concomitant TV repair strategy during left-sided valve surgery is associated with a reduction in cardiac-related mortality and improved echocardiographic TR outcomes at follow-up.
