Congenital Quadricuspid Aortic Valve, a Rare Cause of Aortic Insufficiency in Adults: Case Report

OCLC Number/Unique Identifier: 7286350758

Quadricuspid aortic valve (QAV) is rare congenital malformation of the aortic valve with estimated prevalence of 0.013% to 0.043% [1-4]. QAV is most commonly associated with aortic insufficiency (AI), which is found in almost 75% of cases [5]. QAV can also be associated with other cardiac defects such as ventricular or atrial septal defects, patent ductus arteriosus, subaortic fibromuscular stenosis, malformation of the mitral valve, and coronary anomalies [3]. Up to 40% of all patients with QAV undergo aortic valve replacement surgery most commonly due to progressive AI in 88% of case [2,3,6]. Here we report a case from our institution of a woman with QAV with severe AI and anomalous origin of the right coronary artery.

Fetal Ductal Constriction due to Maternal Intake of Metamizole

Published on: 4th October, 2023

The prevalence of intra-uterine dysfunction of ductus arteriosus is unknown and the clinical consequences are poorly understood. We report a case of prenatal diagnosis of premature closure of the ductus arteriosus due to maternal intake of metamizole during pregnancy. Fetal echocardiography at 37 weeks of gestation revealed a right ventricular hypertrophy and suspected stenosis of the tricuspid valve. A cesarean section led to an excellent neonatal outcome. The aim of this report is to show echocardiographic abnormalities and outcomes of this rare phenomenom.
