AIMS: Foramen ovale (FO) valve with a shape or motion abnormality is frequently detected during routine obstetric ultrasonic examinations. However, the hemodynamics mechanism of this entity remains unclear. The purpose of the study is to determine the relevance of interatrial communication restriction and resultant morphological modifications. MATERIALS AND METHODS: We reviewed the echocardiographic records of fetuses with isolated abnormal FO valve evaluated between January of 2010 and december of 2016...

Advances in prenatal imaging have improved the examination of the fetal cardiovascular system. Fetal echocardiography facilitates the prenatal diagnosis of congenital heart disease (CHD) and through sequential examination, allows assessment of fetal cardiac hemodynamics, predicting the evolution of anatomical and functional cardiovascular abnormalities in utero and during the transition to a postnatal circulation at delivery. This approach allows detailed diagnosis with prenatal counseling and enables planning to define perinatal management, selecting the fetuses at a risk of postnatal hemodynamic instability who are likely to require a specialized delivery plan...

BACKGROUND: Narrow pulse pressure has been demonstrated to indicate low central volume status. In critically ill patients, volume status can be qualitatively evaluated using Doppler velocimetry to assess hemodynamic changes in the carotid artery in response to autotransfusion with passive leg raise (PLR). Neither parameter has been prospectively evaluated in an obstetric population. The objective of this study was to determine if pulse pressure could predict the response to autotransfusion using carotid artery Doppler in healthy intrapartum women...

BACKGROUND: Bleeding from hemorrhagic shock can be immediately controlled by blocking the proximal part of the hemorrhagic point using either resuscitative thoracotomy for aortic cross-clamping or insertion of a large-caliber (10-14Fr) resuscitative endovascular balloon occlusion of the aorta (REBOA) device via the femoral artery. However, such methods are very invasive and have various complications. With recent progress in endovascular treatment, a low-profile REBOA device (7Fr) has been developed...

Several techniques have been proposed to prevent hypotension in obstetric patients. Ephedrine and phenylephrine are individually used to prevent maternal hypotension; however, each has its own drawbacks. Some researchers have reported that the infusion of combined ephedrine and phenylephrine immediately after spinal anesthesia for cesarean delivery reduces the incidence of maternal hypotension. Other studies have indicated that the combination is not superior to the infusion of an individual agent. The present study aimed to evaluate the effect of prophylactic infusion of ephedrine and phenylephrine before the induction of spinal anesthesia for cesarean section on maternal hemodynamic...

Optimal choice of delivery site after a diagnosis of congenital heart disease (CHD) improves neonatal mortality and morbidity. We report the CHU of Liège experience and review the international recommendations. Between 2011 and 2016, 54 fetuses were diagnosed with CHD in our service. Retrospectively we estimated the appropriateness of the site of delivery considering the postnatal outcome. We confronted our experience with the recent international recommendations for in utero transfer to a tertiary center...

Anesthesiologists are responsible for the safe and effective provision of analgesia for labor and anesthesia for cesarean delivery and other obstetric procedures. In addition, obstetric anesthesiologists often have a unique role as the intensivists of the obstetric suite. The anesthesiologist is frequently the clinician with the greatest experience in the acute bedside management of a hemodynamically unstable patient and expertise in life-saving interventions. This review will discuss (1) risks associated with neuraxial and general anesthesia for labor and delivery, and (2) clinical scenarios in which the obstetric anesthesiologist is commonly called upon to function as a "peridelivery intensivist...

Interventional radiologists are often called for emergent control of abnormal uterine bleeding. Bleeding, even heavy bleeding as a result of uterine fibroids is not a common emergent procedure; instead, pregnancy and pregnancy related conditions, trauma and malignancy associated with bleeding can be the source of many interventional radiology on call events or procedures. Postpartum hemorrhage (PPH) is the most common cause, and is defined as blood loss of 500mL after vaginal delivery or 1000mL after cesarean section...

Obstetric cortical renal necrosis is a serious complication that can lead to chronic renal failure and the need for chronic dialysis. The aim of renal cortical necrosis therapy is to restore hemodynamic stability, institute early dialytic therapy, and treat the underlying cause of the disease. Most cases of renal cortical necrosis do not recover a normal renal function despite intensive care. We describe the course of a patient who was diagnosed with acute renal cortical necrosis in pregnancy treated with hemodialysis for three years but then she recovered her renal function...

BACKGROUND: Prophylactic administrations of ondansetron or phenylephrine have been reported to provide a protective effect against hypotension in women undergoing cesarean delivery under spinal anesthesia (SA). The main hypothesis is that ondansetron improves the hemodynamic response, especially combined with phenylephrine infusion. METHODS: This prospective, double-blind, randomized, placebo-controlled study included 265 healthy pregnant women scheduled for elective cesarean delivery under SA...

Advances in cardiac surgical interventions in infancy and childhood have led to an increased number of women with congenital heart disease of childbearing age. For these women, individualized preconception counseling and pregnancy planning should be a vital component of their medical management, and presentation for obstetric care may even be an opportunity to re-establish cardiovascular care for patients who have been lost to follow-up. These patients have unique cardiovascular anatomy and physiology, which is dependent upon the surgical intervention they may have undergone during childhood or adolescence...

The use of intra-aortic balloon counter-pulsation for circulatory support in pregnant women with cardiac failure is limited to several case reports. Few publications have addressed the use of intra-aortic balloon counter-pulsation during delivery. We report a case using prophylactic intra-aortic balloon counter-pulsation during the management of a cesarean delivery in a patient with peripartum cardiomyopathy. A 28-year-old primigravid female at 37weeks of gestation was admitted with signs of worsening heart failure, and transthoracic echocardiography revealed a decreased left ventricular ejection fraction of 25%...
