Rotablation in the treatment of high-risk patients with heavily calcified left-main coronary lesions.

Objective: Heavily calcified left-main coronary diseases (LMCA) remain a formidable challenge for percutaneous interventions (PCI). This study was to investigate the safety and efficacy of using rotational atherectomy (RA) in treating such lesions in actual practice.

Methods: From February 2004 to March 2012, all consecutive patients who received RA for heavily-calcified LMCA lesions in our cath lab were enrolled.

The use and clinical outcomes of rotablation in challenging cases in the drug-eluting stent era.

Background: Rotational atherectomy (RA) has been advocated in the bare metal stent (BMS) era but is underused now due to technique demands and nonsuperior outcomes. The aim of this study was to evaluate the procedural and clinical outcomes of patients with very complex, severely calcified coronary lesions treated by RA and drug-eluting stents (DESs) in our current percutaneous coronary intervention (PCI) practice in a region where RA use has been limited by lack of insurance reimbursement.

Methods: From March 2004 to November 2010, all consecutive patients who required RA treatment for severely calcified de novo lesions of native coronary arteries followed by DES implantation were queried from the cath lab database and recruited.

The short-/intermediate-term changes in novel vascular inflammatory markers after angioplasty plus stenting in patients with symptomatic advanced systemic arterial diseases.

Studies on cell adhesion molecules and high-sensitivity C-reactive protein (hs-CRP) in systemic arterial diseases are limited in numbers and some results not consistent. It also remains undefined whether, for how long and to what extent these markers are perturbed after angioplasty. Patients with systemic arterial diseases admitted for percutaneous transluminal angioplasty (PTA) by standard procedures and techniques were prospectively studied.
