Implication

Wedge pressure ≥30 mm Hg may identify recruitable collaterals during PTCA; leaves open its added value in prospective risk-stratification studies.

Does coronary wedge pressure predict the presence of recruitable collaterals in patients undergoing PTCA?

Population

49 patients undergoing percutaneous transluminal coronary angioplasty (PTCA) for a proximal coronary stenosis or occlusion (57 coronary arteries assessed)

Intervention

Measurement of coronary wedge pressure during a 30 sec or longer balloon occlusion

Comparator

Comparison between arteries with spontaneously visible collaterals, recruitable collaterals, and no collaterals

Outcome

Coronary wedge pressure in relation to the presence of spontaneously visible or recruitable collateralssurrogate

A coronary wedge pressure of 30 mm Hg or higher during balloon occlusion exclusively predicts the presence of coronary collaterals.

Limitations

Clinical impact remains to be investigated in long-term studies on large patient populations
