RESUMEN
BACKGROUND: Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) have been shown to improve the clinical outcomes of percutaneous coronary interventions (PCIs) in selected subsets of patients. AIM: The aim was to investigate whether the use of OCT or IVUS during a PCI with rotational atherectomy (RA-PCI) will increase the odds for successful revascularization, defined as thrombolysis in myocardial infarction (TIMI) 3 flow. METHODS: Data were obtained from the national registry of PCIs (ORPKI) maintained by the Association of Cardiovascular Interventions (AISN) of the Polish Cardiac Society. The dataset includes PCIs spanning from January 2014 to December 2021. RESULTS: A total of 6522 RA-PCIs were analyzed, out of which 708 (10.9%) were guided by IVUS and 86 (1.3%) by OCT. The postprocedural TIMI 3 flow was achieved significantly more often in RA-PCIs guided by intravascular imaging (98.7% vs. 96.6%, p < 0.0001). Multivariable analysis revealed that using IVUS and OCT was independently associated with an increased chance of achieving postprocedural TIMI 3 flow by 67% (odds ratio (OR), 1.67; 95% confidence interval (CI): 1.40-1.99; p < 0.0001) and 66% (OR, 1.66; 95% CI: 1.09-2.54; p = 0.02), respectively. Other factors associated with successful revascularization were as follows: previous PCI (OR, 1.72; p < 0.0001) and coronary artery bypass grafting (OR, 1.09; p = 0.002), hypertension (OR, 1.14; p < 0.0001), fractional flow reserve assessment during angiogram (OR, 1.47; p < 0.0001), bifurcation PCI (OR, 3.06; p < 0.0001), and stent implantation (OR, 19.6, p < 0.0001). CONCLUSIONS: PCIs with rotational atherectomy guided by intravascular imaging modalities (IVUS or OCT) are associated with a higher procedural success rate compared to angio-guided procedures.
RESUMEN
The optimal and the most effective treatment of pulmonary embolism is still a matter of concern and each day sees a new set of challenges for the world of medicine. The progress, has been made in recent years, improved quality of life and caused much better treatment results. This is difficult issue in patients, receiving anticoagulant therapy, because they require an individual approach and adjustability to the therapeutic possibilities. The benefits of long-term anticoagulant therapy, which decreases relapses of idiopathic venous thromboembolism and diminishes risk of thromboembolic complications, should be taking under consideration. It is still a matter of dispute the time of carrying out of treatment, especially after the first life idiopathic episode of pulmonary embolism. The purpose of this paper is an overview and a summary of the foregoing achievements concerned the standards of idiopathic pulmonary embolism treatment, expecting benefits flowing with using new oral anticoagulants, as an alternative to known for decades Vitamin K antagonist drugs. A lot of information about new oral anticoagulants speaks in favor of their use, but unknown safety of the drugs caused searching the best strategy of pulmonary embolism treatment all the time.
