Cardiac Catheterization I: Pre-Procedure Overview01:28

Cardiac Catheterization I: Pre-Procedure Overview

1.6K
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Mitral Stenosis II: Clinical features and Diagnostic Tests

299
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Medical Devices

Background:

  • Symptomatic severe tricuspid regurgitation (TR) has a poor prognosis if left untreated.
  • Surgical repair or replacement for TR carries a very high risk for many patients.
  • Transcatheter interventions are emerging as less invasive alternatives for TR treatment.

Purpose of the Study:

  • To describe the step-by-step technique for transcatheter tricuspid repair using the MitraClip system.
  • To present the latest worldwide experience and results of tricuspid clipping procedures.
  • To highlight the use of echocardiographic and fluoroscopic guidance in the procedure.

Main Methods:

  • Utilizing the TriClip system, which involves the MitraClip NT device delivered via a specialized tricuspid steerable guide catheter.
  • Performing transcatheter tricuspid repair under combined echocardiographic and fluoroscopic guidance.
  • Reviewing data from over 300 worldwide transcatheter tricuspid repair procedures.

Main Results:

  • Transcatheter tricuspid repair with the MitraClip system has demonstrated promising initial results.
  • Over 300 procedures have been performed globally, indicating growing adoption.
  • The technique allows for a less invasive treatment option for high-risk patients.

Conclusions:

  • Transcatheter tricuspid repair is an emerging and promising option for severe TR in high-risk patients.
  • The MitraClip system, delivered via the TriClip system, is under investigation for this indication.
  • Further data on worldwide experience support the viability of tricuspid clipping.
