Left heart catheterization including intraprocedural injection(s) for left ventriculography, imaging supervision and interpretation, when performed

Left heart catheterization is a diagnostic procedure that involves the insertion of a catheter into the left side of the heart to assess its function and structure. This procedure typically begins with the cleansing of the skin over a selected artery, such as the brachial, axillary, or femoral artery, followed by the administration of a local anesthetic to minimize discomfort. A needle is then used to puncture the artery, and a sheath is placed to facilitate the introduction of a guidewire. Under radiological supervision, the guidewire is carefully threaded retrograde through the artery and into the aorta, ultimately reaching the left side of the heart, which includes the left ventricle and left atrium. A catheter is then advanced over the guidewire, which is subsequently removed. During the procedure, the aortic valve, left ventricle, mitral valve, and left atrium are inspected for any abnormalities. Additionally, left ventricular and atrial pressures are measured, and pressure gradients across the aortic and mitral valves are assessed to evaluate cardiac function. Contrast media may be injected to obtain a left ventriculogram, which provides detailed imaging of the left ventricle's structure and function. In some cases, a separately reportable angiogram of the aorta may also be performed to visualize the aorta's condition. Upon completion of the procedure, the catheter is withdrawn, and compression is applied to the arterial puncture site to prevent bleeding, followed by the application of a compression dressing. The results of the left heart catheterization and ventriculogram are thoroughly reviewed, and a written report detailing the findings is generated for further evaluation and management.
