Application of excimer laser coronary atherectomy
guided by optical coherence tomography in the treatment of a severe calcified coronary lesion.
Percutaneous directional coronary atherectomy
(DCA) had been utilized dating back to late 1980s as an adjunctive procedure during percutaneous coronary intervention (PCI) for the reduction of plaque volume, especially for bifurcation or ostium lesions [1, 2].
Three patients were refused surgery and 22 patients did not meet the criteria for coronary atherectomy
during CABG then they are excluded.
This had been used in coronary atherectomy
for some time and has an indication in the periphery as well.
Exclusion criteria: 1) obviously combined with liver and kidney dysfunctions, tumors, or other diseases such as myocarditis, heart failure and left ventricu- lar ejection fraction Less than 30 Percent that may elevate creatine kinase-MB isoenzyme (CK-MB) activities and car- diac troponin I (cTnI) levels; 2) without combined diseases but with elevated preoperative baseline cTnI levels and CKMB activities; 3) Application of rotational ablation or directional coronary atherectomy
; 4) intraoperative serious blood vessel compli- cations and main branch obliteration, below grade 2 Thrombolysis in Myocardial Infarction (TIMI) confirmed by postoperative angiography; 5) pa- tients who were allergic to trimetazidine.7 All the included patients have signed the informed consent forms.
The study population consisted of 26 consecutive male patients with stable angina pectoris (Canadian Cardiovascular Society Class 2) underwent elective coronary atherectomy
Similar findings on the lack of association between CRP and angiographic restenosis have also been reported in 75 patients treated with directional coronary atherectomy
(20), in a report from Dibra et al.
Our CVX-300(R) excimer laser is the only system approved by the FDA for multiple cardiovascular procedures, including coronary atherectomy
, the treatment of in-stent restenosis prior to radiation therapy, and the removal of problematic pacemaker and defibrillator leads.
