Ask Dr. Z

Should this be 93451 (right heart cath) or 93453 (left and right heart cath)?

Patient with CM. Consult report indicates: Severe reduction in LV systolic function & CAD. Considering LVAD while pt waits for heart tx.

Arterial & venous access. Patient given Nipride.

Final diagnosis HFrEF w/severe elevation left heart pressures w/mild elevation right heart filling pressures. Severe elevation Pulmonary arterial pressures with mild elevation PVR. Compensated right heart function (RAP: PAWP 0.27, PAPi 4.7). Improvement in cardiac output and decrease in filling pressures and pulmonary arterial pressures with afterload/preload reduction.

Left heart filling pressures were severely elevated (PAWP 33 with V wave to 57 and pre-A wave 24); the elevation in pre-A/diastolic PAWP pressures in the absence of mitral stenosis is consistent with marked elevation in LV diastolic pressures. Pulmonary arterial pressures were severely elevated (PA 71/29/46) while femoral arterial pressures were 115/65/81, thus 62% systemic. Cardiac output was low (CI 1.8 L/min/m2) by measured Fick. Pulmonary vascular resistance was mildly elevated (PVR 3.6 WU).
