Acute maternal hyperoxygenation to predict hypoxia and need for emergency intervention in fetuses with transposition of the great arteries: a pilot study.

Background: Newborns with transposition of the great arteries (TGA) are at risk of severe hypoxia from inadequate atrial mixing, closure of the arterial duct and/or pulmonary hypertension (PPHN). Acute maternal hyperoxygenation (AMH) might assist in identifying at-risk fetuses. We report pulmonary vasoreactivity to AMH in TGA fetuses and its relationship to early postnatal hypoxia and requirement for emergency balloon atrial septostomy (e-BAS).

Background: Patients with end-stage heart failure and low pulmonary capillary wedge pressure are referred to as cold and dry and represent an understudied minority in whom the benefit of left ventricular assist device (LVAD) therapy is unclear.
Methods: Adults receiving LVADs between 2006 and 2017 in the Interagency Registry for Mechanically Assisted Circulatory Support database were classified as cold and wet (pulmonary capillary wedge pressure >15 mm Hg) and cold and dry (pulmonary capillary wedge pressure ≤15 mm Hg) based on pre-LVAD hemodynamics obtained via right heart catheterization. The primary outcome was 1-year survival.
Utility of Simultaneous Left Atrial Strain-Volume Relationship During Passive Leg Lift to Identify Elevated Left Ventricular Filling Pressure-A Proof-of-Concept Study.

: The assessment of left ventricular (LV) filling pressure in heart failure (HF) poses a diagnostic challenge, as HF patients may have normal LV filling pressures at rest but often display elevated LV filling pressures during exercise. Rapid preload increase during passive leg lift (PLL) may unmask HF in such challenging scenarios. We explored the dynamic interplay between simultaneous left atrial (LA) function and volume using LA strain/volume loops during rest and PLL and compared its diagnostic performance with conventional echocardiographic surrogates to detect elevated LV filling pressure.

: The current classification of pulmonary hypertension (PH) distinguishes between pre-capillary (PAWP ≤ 15 mmHg) and post-capillary (PAWP > 15 mmHg) forms, with left heart disease, especially heart failure with preserved ejection fraction (HFpEF), being a common cause of PH. We investigated the suitability of an HFpEF diagnosis instead of PAWP in diagnosing PH associated with HFpEF. : In a retrospective, single-center analysis, we reviewed diagnoses from our database, focusing on patients initially diagnosed with idiopathic pulmonary arterial hypertension (IPAH) or PH associated with HFpEF (PH-HFpEF) based on their PAWP.

To assess the prenatal course and early postnatal outcomes of fetuses diagnosed with tricuspid atresia and to identify predictors of survival. This was a retrospective study of 25 fetuses diagnosed with tricuspid atresia in a single tertiary referral center, evaluating prenatal echocardiographic features and postnatal outcomes. A total of 4 of 29 initially diagnosed fetuses were excluded due to changes in diagnosis or loss to follow-up, leaving 25 fetuses for analysis.
