Background. Chronic total occlusion (CTO) of coronary artery still represents one of the most challenging lesion subset in field of interventional cardiology. Considering the complexity and increased risk posed by the retrograde approach, it is most often performed after a failed antegrade approach. Methods. We present a series of cases dedicated to the retrograde approach as a special technique for the treatment of chronic total coronary artery occlusion. All cases have some special characteristics that are today part of a dedicated portfolio in every cath lab. Results. In our series of cases all of three percutaneous coronary interventions (PCI) with retrograde approach finished with successful recanalization of CTO with different strategy and supported with rotational atherectomy (RA) or intravascular ultrasound (IVUS). Conclusion. In cases where there is the presence of interventional collaterals, as well as when the anterograde approach is very difficult, the retrograde approach can increase the success rate of procedures. The retrograde approach requires a long learning curve as well as very skilled and experienced operators who are able to perform the procedure independently.

Postischemic myocardial dysfunction affects morbidity and mortality in patients with coronary artery disease. It is known that mechanical unloading of the left heart ventricle can positively influence postischemic myocardial dysfunction. In this respect we tested two miniaturised axial flow pumps, i.e. the 14-F and the 21-F Hemopump®. An experimental study was carried out on 30 open chest sheep where regional myocardial wall motion was followed using sonomicrometry in a preparation of transient coronary artery occlusion. Only the larger 21-F Hemopump® showed hemodynamically significant unloading of the left ventricle. Furthermore, as far as stunning is concerned, systolic wall thickening recovered better when this type of pump was used during reperfusion. Also postejection thickening, which is an indication of diastolic postischemic dysfunction, is reduced significantly in the postischemic area (ANOVA, p<0.05). Thus, the 21F Hemopump®, but not the 14F Hemopump®, provides adequate mechanical unloading in order to beneficially influence myocardial stunning.
