Management of Fetal Supraventricular Tachycardia: Case Series from a Tertiary Perinatal Cardiac Center.

Background: Fetal supraventricular tachycardia is a relatively uncommon cardiac rhythm abnormality which is often associated with adverse perinatal outcomes if untreated. Although there are several treatment modalities and protocols in use globally, there is no consensus as to the most effective antiarrhythmic to manage this condition.

Aim: This study aimed to evaluate perinatal outcomes following prenatal maternal therapy for fetal supraventricular tachycardia.

Longitudinal assessment of ventricular strain, tricuspid and mitral annular plane systolic excursion (TAPSE and MAPSE) in fetuses from pregnancies complicated by diabetes mellitus.

Objectives: To evaluate fetal cardiac function using myocardial deformation analyses, tricuspid annular plane systolic excursion (TAPSE), mitral annular plane systolic excursion (MAPSE) and diastolic function parameters in pregnancies complicated by maternal diabetes mellitus.

Methods: Myocardial deformation using velocity vector imaging (VVI), TAPSE, MAPSE and diastolic function was measured in 126 women with uncomplicated singleton pregnancies and 50 women with diabetes mellitus. Women underwent ultrasound scans every four weeks from recruitment (18-28 weeks gestational age) until delivery.

Global longitudinal reference ranges for fetal myocardial deformation in the second half of pregnancy.

Purpose: To construct longitudinal fetal reference ranges for global longitudinal myocardial deformation (strain and strain rate) of the left and right ventricles in the second half of pregnancy.

Methods: A prospective, observational, longitudinal study of 120 women with uncomplicated singleton pregnancies. The participants underwent ultrasonographic scans every 4 weeks from enrolment (18-28 weeks) until delivery.

Longitudinal Reference Ranges for Tricuspid Annular Plane Systolic Excursion and Mitral Annular Plane Systolic Excursion in Normally Grown Fetuses.

Objectives: The aim of this study was to construct reference ranges for fetal tricuspid annular plane systolic excursion (TAPSE) and mitral annular plane systolic excursion (MAPSE) using conventional M-mode ultrasound (US) in the second half of pregnancy.

Methods: Participants underwent US scans every 4 weeks from 18 weeks' gestation until delivery. The TAPSE and MAPSE were measured by conventional M-mode US at each examination.

Secondary repair of Ebstein's anomaly with atrioventricular septal defect using the cone technique.

A nine-year-old boy with incomplete atrioventricular septal defect (AVSD) and Ebstein's anomaly had undergone a closure of primum atrial septal defect and repair of right and left AV valves at four years of age. He presented with severe regurgitation of the right AV valve. He underwent further surgery, and a cone reconstruction of the right AV valve was performed.

Use of β-blockade and levosimendan for separation from extracorporeal life support in an infant with postoperative diastolic dysfunction.

Diastolic dysfunction is common in infants and neonates with left ventricular (LV) outflow tract obstruction and may lead to low-cardiac output in the postoperative period. We present a management strategy for severe postrepair diastolic dysfunction in an infant with critical congenital aortic stenosis and LV hypertrophy, employing β-blockade and levosimendan.
