The concept of cone creation to treat isolated tricuspid valve dysplasia and the case of a double-orifice tricuspid valve.

Objectives: Isolated tricuspid valve dysplasia is a rare disease characterized by a wide spectrum of possible anomalies. We describe the use of the Cone concept to treat a patient with a double-orifice tricuspid valve with massive regurgitation and severe deficit of coaptation.

Methods: Three adult patients with congenital non-Ebstein tricuspid valve anomaly characterized by severe coaptation deficiency underwent tricuspid valve repair applying the Cone technique.

Bentall Endocarditis by After COVID-19: The Finger Covers The Moon.

We report a case of endocarditis months after a Bentall procedure. This was caused by in an immunocompetent patient with a recent SARS-CoV-2 infection. The patient underwent a new Bentall procedure.

Staged approach for correction of anomalous venous return to the azygos vein.

Partial anomalous pulmonary venous return into the azygous vein is a rare pathological finding. We describe the case of a 28-year-old girl who had a successful staged approach to treat this rare congenital heart disease. To avoid potential connection of a systemic venous return to the left atrium, the proximal part of the azygous vein was occluded with a percutaneous approach, then the azygous vein flow was redirected into the left atrium with a surgical procedure.

Myocardial oxygen consumption during histidine-tryptophan-ketoglutarate cardioplegia in young human hearts.

Objectives: Energy demand and supply need to be balanced to preserve myocardial function during paediatric cardiac surgery. After a latent aerobic period, cardiac cells try to maintain energy production by anaerobic metabolism and by extracting oxygen from the given cardioplegic solution. Myocardial oxygen consumption (MVO2) changes gradually during the administration of cardioplegia.

[Anomalous origin of the right coronary artery from the pulmonary artery or coronary artery fistula: when the diagnosis is uncertain].

The anomalous origin of the right coronary artery from the pulmonary artery is a rare congenital coronary anomaly with a reported incidence of approximately 0.002%. Usually, the diagnosis is made by echocardiography leaving computed tomography or angiography only to diagnostic completion in doubtful cases or for interventional procedures.
