Cardiac Catheterization III: Left Heart Catheterization

240
Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...

Cardiac Catheterization II: Right Heart Catheterization

191
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Area of Science:

  • Cardiology
  • Electrophysiology
  • Medical Devices

Background:

  • Left bundle branch area pacing (LBBAP) traditionally uses lumen-less pacing leads (LLL) with fixed helix.
  • This study investigates an alternative approach using stylet-driven leads (SDL) with an extendable helix design.

Purpose of the Study:

  • To evaluate the safety and feasibility of LBBAP using SDL in a multicenter patient population.
  • To assess implant success, complications, and pacing characteristics of SDL-LBBAP.

Main Methods:

  • A prospective registry study enrolled 353 patients undergoing LBBAP for bradycardia or heart failure.
  • LBBAP was performed using SDL (Solia S60) via a dedicated delivery sheath (Selectra3D).
  • Data on implant success, complications, and pacing parameters were collected at implant and follow-up.

Main Results:

  • LBBAP with SDL was successful in 94% of patients (334/353), with high success rates across centers.
  • Pacing response was identified as LBBAP in 73% of cases.
  • Low and stable pacing thresholds were observed, with minimal lead revisions (1.4%) and few complications (e.g., septal perforations in 2%).

Conclusions:

  • Stylet-driven leads are a safe and feasible option for LBBAP.
  • The technique offers high implant success, low complication rates, and stable pacing parameters.
  • SDL-LBBAP is a viable alternative for both low and high-volume centers.
