CARDIOVASCULAR Advanced management solutions for calcified lesions In an ageing and comorbid population with a high incidence of severely calcified coronary and peripheral lesions, advanced debulking techniques are frequently necessary in order to offer optimal interventional and endovascular treatment results Grigorios Korosoglou MD Sorin Giusca MD PhD Department of Cardiology, Vascular Medicine and Pneumology, GRN Hospital Weinheim, Weinheim, Germany Martin Andrassy MD Fuerst-Stirum Hospital, Cardiology & Vascular Medicine, Bruchsal, Germany The incidence of coronary, peripheral artery (CAD and PAD) and cerebrovascular diseases is rising in the western world, within an ageing population with comorbidities such as diabetes mellitus, renal failure and obesity. Despite advances in pharmacological treatment, many patients with CAD and PAD require invasive treatment to reduce the symptoms of angina or claudication, salvage myocardial or peripheral muscle, and prevent cardiac death or amputation with subsequent disability in those presenting with acute coronary syndromes (ACS) or critical limb ischaemia (CLI), respectively. For both CAD and PAD, endovascular techniques are widely accepted as first-choice treatment options in most patients. This is attributed to significant technological advances over the last decades. However, in patients with severely calcified or/and chronically totally occluded (CTO) coronary or peripheral lesions, antegrade wire passage may be difficult due to the presence of severe calcification in the area of the proximal cap of the occlusion. In 6 HHE 2019 | hospitalhealthcare.com addition, even in cases of successful antegrade or retrograde wire passage, standard interventional treatment options, such as balloon angioplasty, drug-coated balloon (DCB) angioplasty and stent placement may fail. In such cases, advanced techniques may become necessary for tackling such complex and calcified lesions. Advanced age, diabetes mellitus and renal disease, especially chronic haemodialysis, have all been associated with increased coronary and peripheral artery calcification, increasing the need for advanced endovascular techniques beyond balloon angioplasty and stent placement in such patients. Complex and calcified coronary lesions Despite modern coronary drug-eluting stent (DES) technologies, calcified coronary lesions remain a great challenge in interventional cardiology. Thus, severe and especially concentric calcification is associated with inadequate balloon expansion and recoil after balloon angioplasty and with failure to deliver a stent or with
