Many researchers have reported on the high prevalence of anxiety and depression during pregnancy as well as the influence on delivery outcomes during the past decade. Preterm birth and premature labor, bleeding, higher frequency of cesarean section (CS), low birth weight, preeclampsia, stillbirth, miscarriage, NICU hospitalization, and a low Apgar score are the most commonly referenced outcomes assessed. Clarifying the relationship between exposure and result may help us to understand the risk factors and guide us to future clinical and research practices.

Asynclitism, the most feared malposition of the fetal head during labor, still represents to date an unresolved field of interest, remaining one of the most common causes of prolonged or obstructed labor, dystocia, assisted delivery, and cesarean section. Traditionally asynclitism is diagnosed by vaginal examination, which is, however, burdened by a high grade of bias. On the contrary, the recent scientific evidence highly suggests the use of intrapartum ultrasonography, which would be more accurate and reliable when compared to the vaginal examination for malposition assessment.

Authors investigated the catecholaminergic neurotransmitters (chNs) quantitative modifications in pregnant uterine Lower Uterine Segment (LUS) during prolonged labor (PL) with the fetus in an occiput-posterior position (OPP), in occiput transverse position (OTP) and in fetal head asynclitism, all diagnosed by Intrapartum Ultrasonography (IU). The chNs neurotransmitters, particularly adrenaline (or epinephrine-A) and noradrenaline (or norepinephrine-N), were evaluated in LUS fragments sampled during CS of 34 patients undergoing urgent cesarean section (CS) in PL, compared to chNs fibers in the LUS of 36 women submitted to elective CS. All results were statistically analyzed to understand the differences in neurotransmitters morphological analysis by scanning electronic microscopy examination (SEM).

Background: Valve-in-valve transcatheter aortic valve implantation (TAVI) has emerged as a competent alternative for the treatment of degenerated bioprosthetic valves after surgical aortic valve replacement, or during TAVI procedure as a bailout option. Herein, we report a rare case of a self-expandable Medtronic Evolut R valve into a failing Medtronic CoreValve, with the use of modern pre-TAVI imaging screening, suggesting the proper procedural design steps for so complicated implantations.

Case Summary: A frail 78-year-old woman with a degenerated Medtronic Core Valve 26 mm bioprosthesis, implanted in 2011 due to severe aortic stenosis, was referred to our hospital due to worsening dyspnoea New York Heart Association III.

The growth of the available transcatheter treatment approaches for the mitral and tricuspid position was accompanied by important clinical trials and studies through the last years. The selection of appropriate candidates for transcatheter techniques requires significant insight into anatomical limitations of each patient undergoing clinical evaluation. Furthermore, technological characteristics of the available devices, and risks and benefits of each potential therapy, play the most important role in a physician's decision.
