transcatheter aortic valve implantation Archives

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Management of patients with cardiac amyloidosis and concomitant high-grade aortic stenosis is challenging. This article reports the case of a 79-year-old man with transcatheter aortic valve implantation (TAVI) complicated by low cardiac output during release of a Medtronic Evolut R 34 mm valve. After initiation of mechanical circulatory support, the TAVI valve was successfully implanted despite ongoing ventricular fibrillation. The ventricular fibrillation was successfully treated with injection of potassium into the aorta, with subsequent defibrillation and ventricular pacing. Moreover, pharmacological management of transient severe LV dysfunction and high-grade mitral regurgitation finally led to a favourable course.

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Transcatheter aortic valve replacement (TAVR) is currently a widely used option for patients with severe symptomatic aortic stenosis with high to low surgical risk. However, aortic regurgitation (AR) remains an “off-label” indication for TAVR, particularly for patients with mild or absent leaflet calcification or aortic annulus dimensions beyond the size of the bioprosthesis, which increase the risk of dislocation. With advances in transcatheter heart valve devices, the safety and efficacy of TAVR in treating patients with severe pure native AR has gained acceptance.

This article examines current evidence and clinical practice, and presents technological advancements in devices for AR.
