Cardiac Catheterization III: Left Heart Catheterization

Cardiac Catheterization III: Left Heart Catheterization

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...

Summary

This summary is machine-generated.

Percutaneous coronary intervention (PCI) near the left main trunk (LMT) may suppress premature ventricular contractions (PVCs) originating from the left ventricular (LV) summit. This rare case demonstrates long-term PVC suppression following PCI for a complex coronary artery occlusion.

Area of Science:

Cardiology
Interventional Cardiology
Electrophysiology

Background:

Premature ventricular contractions (PVCs) are a known complication of percutaneous coronary intervention (PCI).

Keywords:

left ventricular summit mechanical stress premature ventricular contraction
