Fetal Cardiac Intervention: A Comprehensive Review of Current Evidence.

Fetal cardiac intervention consists of a novel and evolving technique for the intrauterine treatment of a subset of patients with congenital heart diseases, which aims to improve hemodynamics, reduce secondary damage, and achieve better postnatal outcomes. Nevertheless, the risks and benefits of this therapy remains subject to controversy. This review describes the rationale, selection criteria, and technical features for the most frequently performed fetal cardiac interventions.

Fetal cervical sarcoma: Comparison between virtual and real fetal bronchoscopy.

Fetal cervical tumors are a life-threatening condition if proper diagnosis and perinatal care are inadequate. The most common causes of fetal cervical masses are teratomas and lymphangiomas. Less common tumors may obstruct the fetal airway due to cervical compression.

Climate-informed forecasts reveal dramatic local habitat shifts and population uncertainty for northern boreal caribou.

Most research on boreal populations of woodland caribou (Rangifer tarandus caribou) has been conducted in areas of high anthropogenic disturbance. However, a large portion of the species' range overlaps relatively pristine areas primarily affected by natural disturbances, such as wildfire. Climate-driven habitat change is a key concern for the conservation of boreal-dependent species, where management decisions have yet to consider knowledge from multiple ecological domains integrated into a cohesive and spatially explicit forecast of species-specific habitat and demography.

Impact of Preoperative Cervical Length on Pregnancy Outcome in Twin-Twin Transfusion Syndrome.

Objective: To evaluate the impact of preoperative cervical length on pregnancy outcome in monochorionic diamniotic twin pregnancies complicated by twin-twin transfusion syndrome that underwent laser surgery or cord occlusion.

Materials And Methods: Retrospective study of 330 patients stratified by preoperative cervical length (≥25 mm, 16-24 mm,≤15 mm). Maternal characteristics, operative data, and pregnancy outcomes were compared between the cervical length groups as well as between the subgroups of patients with a cervical length≤15 mm according to management (expectant vs.

The heart after surviving twin-to-twin transfusion syndrome.

Background: The persistent changes in cardiac structure and function in children who survived twin-to-twin transfusion syndrome remain a matter of concern and controversy. Current fetal echocardiographic parameters and their postnatal evolution can help improve our understanding of the subject.

Objective: To describe the echocardiographic changes of monochorionic fetuses affected by twin-to-twin transfusion syndrome, the recipient and the donor, before and after laser photocoagulation and to determine their evolution in the third trimester and during their first year of life.
