Left ventricular noncompaction (LVNC) is believed to represent an arrest in the normal process of myocardial compaction, resulting in persistence of both hyper-trabeculation and intra-trabecular recess within the left ventricle. The clinical features of this disease are left ventricular dilatation and systolic dysfunction, which carry a high mortality. Most patients die in infancy, but some cases of LVNC in adults have been reported. To the best of our knowledge, only 4 cases of LVNC with valvular heart disease in adults have recently been operated. We describe a 51-year-old man with LVNC and severe aortic regurgitation and mild mitral regurgitation, who was successfully operated upon with aortic valve replacement using a tissue valve, and mitral valve plasty with bilateral papillary muscle relocation.

Purpose Of Review: Traditionally viewed as a passive player in circulation, the right ventricle (RV) has become a pivotal force in hemodynamics. RV failure (RVF) is a recognized complication of primary cardiac and pulmonary vascular disorders and is associated with a poor prognosis. Unlike treatments for left ventricular failure (LVF), strategies such as adrenoceptor signaling inhibition and renin-angiotensin system modulation have shown limited success in RVF.

Restenosis occurs commonly after aortic coarctation (CoA) repair, usually requiring treatment by balloon dilation. Its effect on physical exercise performance is not documented. A retrospective analysis of exercise testing and echocardiographic assessment was performed in children after CoA repair.

The acute response to therapeutic afterload reduction differs between heart failure with preserved (HFpEF) versus reduced ejection fraction (HFrEF), with larger left ventricular (LV) stroke work augmentation in HFrEF compared to HFpEF. This may (partially) explain the neutral effect of HFrEF-medication in HFpEF. It is unclear whether such differences in hemodynamic response persist and/or differentially trigger reverse remodeling in case of long-term afterload reduction.

The maximal oxygen uptake (V̇O) is typically higher in endurance-trained adolescents than in non-endurance-trained peers. However, the specific mechanisms contributing to this remain unclear, as well as the impact of training during this developmental stage. This study aims to compare V̇O and cardiovascular functions between 12-year-old endurance athletes and non-endurance-trained over a 14-month period.

Background: Low-volume hypertonic solutions, such as half-molar lactate (LAC), may be a potential treatment used for fluid resuscitation. This study aimed to evaluate the underlying cardiovascular effects and mechanisms of LAC infusion compared to sodium-matched hypertonic sodium chloride (SAL).
Methods: Eight healthy male participants were randomized in a controlled, single-blinded, crossover study.
