[Endovascular treatment for chronic coronary occlusions in patients with coronary heart disease]
Insights
Endovascular treatment successfully restored blood flow in 72.1% of patients with chronic coronary occlusions. Physician experience and occlusion characteristics significantly impact success rates for this safe and effective procedure.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Vascular Surgery
Background:
- Chronic coronary occlusions (CCOs) represent a significant challenge in managing coronary heart disease (CHD).
- Endovascular techniques offer a minimally invasive approach to revascularize these complex lesions.
Purpose of the Study:
- To evaluate the angiographic outcomes of endovascular treatment for CCOs in patients with CHD.
- To identify factors influencing the success of recanalization procedures.
Main Methods:
- A cohort of 854 patients with CHD and CCOs underwent attempted endovascular recanalization between 2009 and 2013.
- Data collected included patient demographics, occlusion characteristics (duration, morphology, TIMI grade), and procedural success rates.
Main Results:
- Successful recanalization was achieved in 616 (72.1%) patients.
- Recanalization failure occurred in 238 (27.9%) patients.
- Factors such as occlusion duration, morphological characteristics, and operator experience were found to influence procedural success.
Conclusions:
- Endovascular recanalization of CCOs is a highly effective and relatively safe therapeutic option.
- Optimizing procedural success requires careful consideration of occlusion complexity and operator expertise.
Objective:
To analyze the angiographic results of endovascular treatment for chronic coronary occlusions in patients with coronary heart disease.
Material And Methods:
In 2009 to 2013 attempted endovascu-ar recanalization of chronic coronary occlusions in 854 patients with coronary heart disease. The patients' age ranged from3 6 to 68 years (mean 52 years). The estimated du-ation of occlusion was m1 onth to more than 3 years. There were 193 (22.6%) females and 661 (77.4%) males. 462 (54.1%) patients had a history of myocardial infarction. 738 (86.4%) and 116 (13.6%) patients had true (TIMI grade 0) and functional (TIMI grade i1 occlusions, respectively. Multi- and univascular lesions were found in 683 (79.9%) and 171 (20.1%) patients, respectively. Silent occlusions with preserved myocardial contractility were identified in 165 (19.3%) patients. RRESULTS:Blood flow could be successfully restored in 616 (72.1%) patients. Recanalization of chronic coronary occlusion failed in 238 (27.9%) patients. CCONCLUSION:Recanalization of chronic coronary occlusions is a highly effective and relatively safe technique. The efficiency of the procedure largely depends on the duration of occlusion, its X-ray morphological characteristics, and the experience of a physician.

These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...
