Abstract:

Introduction: dextrocardia - is a congenital heart disease, in which the heart is located in right half of chest. Incidence of ischemic heart disease in patients with dextrocardia is unknown, but some authors write that it is the same as in the general population. Guiding principles of endovascular treatment of chronic total occlusion (CTO) of coronary arteries, consider dualcatheter angiography to be an obligatory option for successful recanalization.

Aim: was to estimate possibilities of DRON-access and various radial accesses in treatment of multivessel disease in a patient with dextrocardia, severe comorbidity, and single vascular access.

Material and methods: we present case report of a 63-year-old female patient, who previously had ischemic stroke with tleft-sided hemiplegia; she was examined before surgery for instability of the prosthesis of right hip joint. Coronary angiography through traditional radial access revealed multivessel lesions of coronary arteries: chronic total occlusion (CTO) of right coronary artery, stenosis of the left anterior descending artery (LAD) in proximal and distal third; eccentric circumflex artery (Cx) stenosis. Further examination revealed: severe spastic paralysis of left hand, occlusion of left common femoral artery, chronic osteomyelitis of right leg with suppuration.

Medical consilium decided to perform staged endovascular revascularization of the myocardium.

For this purpose, to provide access for double-catheter recanalization of CTO and subsequent interventions, DRON-access (Distal radial and Radial One-handed accesses for interventions iN chronic occlusions of coronary arteries) and various radial accesses were used.

Results: at the first stage, using DRON-access, we performed double-catheter angiography and CTO recanalization of right coronary artery (RCA) with stenting. At the second stage, through traditional radial access, we performed angioplasty and stenting of LAD at two levels. After 3 months, control coronary angiography was performed through distal radial access: implanted stents had no signs of restenosis, there was no progression of atherosclerotic process. Patient was discharged to prepare for correction of instability of right hip joint prosthesis.

Conclusions: patients with severe and variable comorbidities require not only a multidisciplinary approach, but also, in various of clinical situations, need personalized approach. The use of DRON-access may allow operators to perform endovascular intervention using double-catheter angiography even in patients with single vascular access, which meets modern criteria for providing care for chronic coronary artery occlusions.

Abstract:

Revascularization strategy definition in acute coronary syndrome in patients with multivessel coronary artery disease is a significant problem of modern intervention cardiology Aim: was to evaluate effectiveness of special PC programs «Sapphire 2015 - Right dominance» and «Sapphire 2015 - Left dominance» designed to the revascularization strategy definition ir acute coronary syndrome patients.

Materials and methods: revascularization strategy of 50 acute coronary syndrome patients was analyzed. In all cases the revascularization strategy was defined by the group of intervention cardiologists with the help of independent experts and special PC programs «Sapphire 2015 - Right dominance» and «Sapphire 2015 - Left dominance». Experts-, physicians-, and soft- based revascularization strategies were compared among themselves.

Results: complete coincidence between expert-based and soft-based revascularization strategies was registered in 66% patients and the incomplete coincidence - in 32% patients. Complete mismatch between expert-based and soft-based revascularization strategies was registered in 2% patients. The complete coincidence between physicians-based and soft-based revascularization strategies was registered in 42% patients and the incomplete coincidence - ir 52% patients. Complete mismatch between physicians-based and soft-based revascularization strategies was registered in 6% patients

Conclusion: as well as experts, special PC programs «Sapphire 2015 - Right dominance» and «Sapphire 2015 - Left dominance» provide success in the revascularization strategy definition 1г acute coronary syndrome patients with multivessel coronary artery disease.
