Left ventricular outflow tract obstruction after transcatheter mitral valve replacement: a case report with a multifaceted approach.

An 83-year-old woman was admitted to our center because of heart failure. Transthoracic echocardiography revealed severe mitral annular calcification resulting in a double mitral valve lesion. After discussion by the heart team, transcatheter mitral valve replacement with Tendyne (Abbott Structural, Santa Clara, CA, USA) was performed.

Surgical management of tumor thrombus into the right atrium.

Renal cell carcinoma represents 3% of solid tumors. In 4-10% of patients, venous tumor thrombosis is present, and 1% reaches the right atrium. Other tumors can be associated with tumor thrombosis.

Usefulness of Self-Expanding Drainage Cannula in Venovenous Extracorporeal Membrane Oxygenation: Tips, Tricks, and Results of an Early Experience.

Inadequate venous drainage decreases the efficiency of extracorporeal membrane oxygenation (ECMO). Pump augmentation may even make it worse due to collapse of the venous system under negative pressures. Furthermore, recirculation is a phenomenon that occurs when oxygenated blood supplied through the infusion cannula is withdrawn directly through the drainage cannula without contributing to the oxygenation of the patient and also compromises the efficacy of the therapy.

Frailty, disability and comorbidity: different domains lead to different effects after surgical aortic valve replacement in elderly patients.

Objectives: Frailty syndrome predicts adverse outcomes after surgical aortic valve replacement. However, disability or comorbidity is frequently associated with preoperative frailty evaluation. The effects of these domains on early and late outcomes were analysed.

Use of self-expanding venous cannula in tricuspid reoperation.

Significant tricuspid regurgitation requiring surgical correction is associated with poor survival in patients undergoing tricuspid valve reoperations. Right chamber dilatation increases the risk of injury during resternotomy. The novel technique of peripheral cannulation using an expandable venous cannula for cardiopulmonary bypass can help to reduce the risk of complications and associated morbidity, thus enhancing the short-term outcomes.
