Transjugular transcatheter edge-to-edge mitral valve repair in a patient with functional mitral regurgitation: a case report.

Eur Heart J Case Rep

January 2025

Department of Cardiovascular Medicine, Sendai Kousei Hospital, 1-20 Tsutsumidori-amamiya, Aoba Ward, Sendai, Miyagi 9810914, Japan.

Article Synopsis
  • The transcatheter edge-to-edge mitral valve repair (M-TEER) using the MitraClip system is usually done via the transfemoral approach, but the transjugular approach can be a viable alternative when the former isn't possible.
  • A 57-year-old man with heart failure and severe functional mitral regurgitation could not undergo the transfemoral approach due to an occluded inferior vena cava, leading to the decision to use the transjugular technique instead.
  • The procedure was successful with no complications, significantly reducing the patient's mitral regurgitation, and he showed sustained improvement a year later.

Article Synopsis
  • Interventions for heart conditions using transcatheter techniques can sometimes create an unintended atrial septal defect (IASD), leading to uncertain clinical outcomes.
  • An 84-year-old female with heart failure and mitral regurgitation underwent TEER treatment, which resulted in both mitral stenosis and an increasing IASD, negatively affecting her cardiac output.
  • Successfully closing the IASD improved her blood pressure and overall condition, suggesting that IASD closure may be beneficial for certain patients after such heart interventions, but careful assessment is necessary.

Background: Mitral annular calcification with valve dysfunction remains a challenging syndrome. Operative risk is high, and available transcatheter therapies are limited.

Methods: This study describes our initial experience with a novel procedure to address large mitral annuli when no surgical or trial-based transcatheter mitral valve replacement device is available.

Background: Atrial fibrillation (AF) is a common arrhythmia in patients with atrial septal defect (ASD). Cryoballoon ablation (CA) is a safe and efficient method for pulmonary vein (PV) isolation in the treatment of AF. Achieving left atrial access may be difficult in patients with atrial septal occluders (ASO) or surgical repair of ASD.

Transcatheter mitral valve-in-valve implantation is a preferred treatment for degenerating mitral bioprosthetic valves in high-risk surgical patients. A balloon-expandable transcatheter heart valve delivered through a postero-inferior transseptal puncture is deployed within the prosthesis over a guidewire secured in the left ventricle. Patients with aneurysmal left atrium and altered angulation between the planes of atrial septum and mitral prosthesis have unstable position of the guidewire that flips out of the left ventricle into the left atrium when the valve delivery system is advanced.
