Transcatheter Treatment of Valvular Heart Disease: A Review.

JAMA 2021 Jun;325(24):2480-2494

Bluhm Cardiovascular Institute and Departments of Medicine and Cardiology, Feinberg School of Medicine, Northwestern University, Chicago, Illinois.

Importance: More than 40 million people are living with either mitral or aortic valve disease worldwide, and more than 180 000 heart valve replacement surgeries are performed each year in the US. Transcatheter valve repair has emerged as an important therapeutic option for patients who are candidates for heart valve replacement.

Observations: All transcatheter valve therapies involve a multidisciplinary team of interventional cardiologists, cardiothoracic surgeons, radiologists, echocardiographers, nurses, and social workers, termed the heart team, to determine the optimal approach for managing each patient. Read More

[Percutaneous implantation of an aortic prosthetic valve on a degenerated mitral bioprosthesis. Report of one case].

Rev Med Chil 2021 Jan;149(1):137-141

Instituto Cardiovascular, Hospital Clínico San Carlos, Madrid, España.

Reintervention of a mitral degenerated bioprosthesis has a high surgical risk, especially in elderly patients with multiple comorbidities. We report a 74 years old female with two previous cardiac surgical procedures and a new structural mitral bioprosthesis deterioration with severe mitral regurgitation. Considering her high-surgical risk, a fully percutaneous treatment was performed with a balloon-expandable aortic valve in mitral position (valve-in-valve) through a transseptal approach with a favorable outcome.

Evaluation and Management of Aortic Stenosis in Chronic Kidney Disease: A Scientific Statement From the American Heart Association.

Circulation 2021 Jun 13;143(25):e1088-e1114. Epub 2021 May 13.

Aortic stenosis with concomitant chronic kidney disease (CKD) represents a clinical challenge. Aortic stenosis is more prevalent and progresses more rapidly and unpredictably in CKD, and the presence of CKD is associated with worse short-term and long-term outcomes after aortic valve replacement. Because patients with advanced CKD and end-stage kidney disease have been excluded from randomized trials, clinicians need to make complex management decisions in this population that are based on retrospective and observational evidence.
