Evaluation of immediate and long-term results of intervention by echocardiography: Can restenosis be predicted?
Coronary artery revascularization with either coronary artery bypass surgery or percutaneous transluminal coronary angioplasty is an effective therapeutic procedure in the management of properly selected patients with coronary artery disease [1, 2]. For patient selection and assessment of procedure efficacy, a functional evaluation of stenosis is mandatory. As stated by Andreas Grüntzig at the dawn of the angioplasty era , “imaging postcatheteriz-ation permits evaluation of the physiologic significance of an observed lesion - to determine the potential effect of dilatation on perfusion distal to the lesion”. In addition, a preangioplasty imaging evaluation “provides a baseline for noninvasive post-angioplasty monitoring of the procedure success. As with the patient who has undergone bypass surgery, subjective symptoms are usually a good guide, but are not sufficient for the longitudinal evaluation of the procedure” .
