Predictors of clinical outcome after rotational atherectomy-facilitated percutaneous coronary intervention in hemodialysis patients.

Background: Percutaneous coronary intervention (PCI) in hemodialysis patients with severely calcified and diffused lesions is associated with extremely high rates of major adverse cardiovascular events (MACE), even when facilitated by rotational atherectomy (ROTA). Potential risk factors for MACE with ROTA-facilitated PCI in hemodialysis patients should be identified.

Methods: We retrospectively analyzed a consecutive cohort of patients from the Sapporo Cardiovascular Clinic database, who were on maintenance hemodialysis with severe calcified lesions and treated with ROTA-facilitated PCI.

Comparison of Drug-Eluting Stent and Plain Old Balloon Angioplasty After Rotational Atherectomy in Severe Calcified and Large Coronary.

Drug-eluting stent (DES) is well known to be effective in severely calcified lesion after rotational atherectomy (ROTA). However, there are still some situations when stents should be avoided and plain old balloon angioplasty (POBA) should be the preferred option. The present study aims to explore whether POBA is comparably effective to DES in large and calcified coronary pretreated by ROTA in clinical outcomes.

Reappraisal Value of a Modified Rotational Atherectomy Technique in Contemporary Coronary Angioplasty Era.

Objectives: To introduce a modified rotational atherectomy (RA) procedure and investigate the early and midterm outcomes of the RA-facilitating diversified percutaneous coronary intervention (PCI) in a large group of aged patients with higher cardiovascular risk.

Background: Previous studies about the outcomes of RA were limited with small sample size and low-risk population.

Methods: Between January 2013 and November 2015, 1169 consecutive patients treated with modified RA-facilitated PCI were retrospectively enrolled, including de novo calcified lesions and in-stent restenosis.

Treatment for in-stent restenosis requiring rotational atherectomy.

Objectives: This study aimed to evaluate the outcomes of patients with in-stent restenosis (ISR) who underwent rotablation (RA) followed by balloon angioplasty (BA), drug-eluting stent (DES) implantation, or drug-coated balloon (DCB) angioplasty.

Background: Interventional treatment of ISR is occasionally challenging. Despite the availability of various percutaneous treatments, the optimal solution remains unclear.

Estimation with Tc-99m tetrofosmin SPECT of salvaged myocardial mass after emergent reperfusion therapy in acute myocardial infarction.

Objectives: The purpose of this study was to validate a new quantitative index of salvaged myocardial mass calculated from Tc-99m tetrofosmin SPECT for evaluating the therapeutic effect of emergent reperfusion therapy in acute myocardial infarction (AMI).

Methods: Tc-99m tetrofosmin SPECT was performed before and after emergent percutaneous transluminal coronary angioplasty (PTCA) in eight patients with AMI. In the pre-PTCA study, Tc-99m tetrofosmin was injected before emergent PTCA.
