Cardiac Catheterization Summary
This catheterization reveals severe multi-vessel coronary artery disease requiring urgent revascularization, most critically a 70% left main stenosis and 90% left circumflex stenosis.
Critical Abnormal Findings
Left Main (LM) - MOST CRITICAL
- 70% mid-to-distal calcific stenosis - This is life-threatening and typically mandates CABG over PCI
Left Circumflex (LCX) - SEVERE
- Aneurysmal ostium with disease
- 90% stenosis - Severe flow-limiting lesion
Left Anterior Descending (LAD) - MODERATE
- Moderate diffuse calcific disease throughout
- 50% mid-vessel stenosis
- D1 branch: small with moderate disease
- D2 branch: medium caliber with mild-to-moderate diffuse disease
Right Coronary Artery (RCA) - MODERATE
- Large dominant vessel
- Moderate diffuse calcific disease throughout
- 50% mid-vessel stenosis
Hemodynamics
- LVEDP = 11 mm Hg (normal: <12 mm Hg, borderline elevated)
- Right dominant system
Clinical Significance
The combination of 70% left main disease with 90% LCX stenosis places this patient at extremely high risk for sudden cardiac death and requires immediate cardiothoracic surgery consultation 1. The extensive calcific burden throughout all vessels indicates advanced atherosclerotic disease with likely need for complete revascularization rather than staged intervention.
The borderline elevated LVEDP suggests early diastolic dysfunction but preserved systolic function, though formal ventriculography findings are not reported here.
