Summary

This study introduces a straightforward method using a dual-lumen pigtail catheter and single radial-arterial access to directly measure the transmitral gradient (TMG) and mitral valve area (MVA). This technique simplifies hemodynamic assessment in cardiac catheterization procedures.

Cardiac Catheterization II: Right Heart Catheterization

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...
