We demonstrate the incremental value of live/real time three-dimensional transthoracic echocardiography (3DTTE) over the two-dimensional modality in the identification of all three cusps of the pulmonary valve in patients in whom only two leaflets could be detected by the latter technique. This was because of the ability of 3DTTE to view the cusps enface permitting assessment of relationship to one another and the surrounding cardiac structures. In addition, 3DTTE showed not only the potential errors that can occur in pulmonary valve cusp identification when the two-dimensional modality is used alone but also how some of these errors can be avoided by paying attention to the surrounding structures.

Transcatheter mitral valve repair with MitraClip® enabling single lung transplantation: A case report.

Department of Cardiology, CHU Mont-Godinne UCL Namur, Yvoir, Belgium.
Post-capillary hypertension resulting from mitral regurgitation is typically considered a contraindication for single lung transplantation due to heightened risks of primary graft dysfunction. This case report highlights a 66-year-old COPD patient with severe mitral regurgitation who was deemed ineligible for surgical mitral replacement. As an alternative, transcatheter mitral valve replacement was successfully performed, resulting in the normalization of pulmonary artery pressures.

Disorders of the pulmonic valve (PV) receive considerably less attention than other forms of valvular heart disease. Due to the dramatically improved survival of children with congenital heart disease over the last 5 decades, there has been a steady increase in the prevalence of adults with congenital heart disease, which necessitates that clinicians become familiar with the anatomy and the evaluation of right ventricular outflow tract and PV anomalies. A multimodality imaging approach using echocardiography, cardiac computed tomography, and magnetic resonance imaging is essential for a comprehensive evaluation of the anatomy and function of the right ventricular outflow tract, PV, and supravalvular region.

Coronary ectasia is a very rare phenomenon seen in Noonan syndrome with only a few documented case reports. We describe a 14-year-old with Noonan syndrome and tetralogy of Fallot with described coronary artery ectasia since infancy who presented for possible transcatheter pulmonary valve placement and was found to have severe ectasia of bilateral coronary arteries.

Background: An effective prognostic nomogram to predict the prognosis for supravalvular aortic stenosis (SVAS) patients is lacking.
Methods: A multi-center retrospective study of consecutive SVAS patients with surgery between 2002 and 2020 was conducted. Patients underwent McGoon repairs, Doty repairs, and other repairs.

Acute cardiovascular disorders are incriminated in up to 33% of maternal deaths, and the presence of sickle cell anemia (SCA) aggravates the risk of peripartum complications. Herein, we present a 24-year-old Caribbean woman with known SCA who developed a vaso-occlusive crisis at 36 weeks of gestation that required emergency Cesarean section. In the early postpartum period, she experienced fever with rapid onset of acute respiratory distress in the context of COVID-19 infection that required tracheal intubation and mechanical ventilatory support with broad-spectrum antibiotics and blood exchange transfusion.
