Regression of collateral function after recanalization of chronic total coronary occlusions: a serial assessment by intracoronary pressure and Doppler recordings.
BACKGROUND Collaterals can maintain myocardial function or preserve viability in chronic total coronary occlusions (CTOs). It is unknown whether and to what extent collaterals regress after successful recanalization of a CTO. METHODS AND RESULTS In 103 patients with successful recanalization of a CTO collateral function was assessed by intracoronary Doppler and pressure recordings before and ...

angioplasty by Gruentzig in 1977, this revascularization technique has been applied to an increasing number of patients and in different clinical scenarios. However, chronic total occlusions are still considered to be a challenge for the interventional cardiologist. It has been estimated that approximately 10% of all angioplasty procedures are currently undertaken for chronic total occlusions. ...
متن کاملCurrent percutaneous recanalization of coronary chronic total occlusion.
Although successful recanalization rates of coronary chronic total occlusions have remained suboptimal in percutaneous coronary interventions, evolving techniques, including the retrograde approach, have raised hopes for better outcomes. With the advent of antiplatelet therapy and drug-eluting stents, along with conventional antegrade approaches, further progress can be expected in the "last fr...
متن کاملFocal stenting versus "metal jacket" for long subintimal recanalization of the femoropopliteal artery.
SEE PAGE 472 L ong chronic total occlusions are a formidable challenge for endovascular recanalization. Patients with critical limb ischemia are at a greater risk of developing advanced disease along with chronic total occlusions requiring revascularization to avoid amputation (1). Over the years, different endovascular techniques have been used to cross long chronic total occlusions. Subintima...
متن کاملImmediate changes of collateral function after successful recanalization of chronic total coronary occlusions.
BACKGROUND Coronary collaterals are essential to maintain myocardial function in chronic total coronary occlusions (TCOs). The aim of the present study was to assess the collateral circulation in TCOs before coronary angioplasty and to determine the recruitable collateral perfusion after recanalization by use of intracoronary Doppler flow velocimetry. METHODS AND RESULTS In 21 patients with T...
