Value of stent boost imaging in decision making after coronary stenting.

BACKGROUND: Several studies reported the comparability of digital stent enhancement techniques (including stent boost imaging) in detecting suboptimal results of coronary stenting with Intra Vascular Ultrasound and optical coherence tomography. AIMS: to assess results of stent deployment and determine the incidence of suboptimal results requiring changing final decision using stent boost imaging. METHODS: This cross-sectional study included 120 patients eligible for PCI were recruited during a period of one year (January 2021 to 2022) using DES. RESULTS: Suboptimal results were found in 38% of the PCI cases with stents (angiography guided). Importantly it was found that improper lesion preparation in our practice could not help improving stent optimization. Also, angiography guided PCI has significant incidence of suboptimal results. Digital stent enhancement techniques like stent boost have significant and important value in better decision making. After adjusting for age and sex, six factors were identified as independent predictors for final decision change (stent length, LAD/RCA affection, proximal segment affection, calcification, and optical coherence tomography. CONCLUSION: This study has confirmed the utility of stent boost for the optimization of PCI in daily practice. Stent Boost is a simple and costless technique that provides an accurate assessment of a deployed stent without extending the procedure time and without more risk. It appears to be useful for the immediate evaluation of stent expansion and optimization of PCI by additional post-dilatation, when appropriate. Future studies are needed to determine whether Stent Boost data will correlate with adverse long-term clinical outcomes in patients undergoing PCI.

Incidence and Clinical Course of Limb Dysfunction Post Cardiac Catheterization　- A Systematic Review.

BACKGROUND: We systematically reviewed the available literature on limb dysfunction after transradial access (TRA) or transfemoral access (TFA) cardiac catheterization. Methods and Results: MEDLINE and EMBASE were searched for studies evaluating any transradial or transfemoral procedures and limb function outcomes. Data were extracted and results were narratively synthesized with similar treatment arms. The TRA group included 15 studies with 3,616 participants and of these 3 reported nerve damage with a combined incidence of 0.16% and 4 reported sensory loss, tingling and numbness with a pooled incidence of 1.61%. Pain after TRA was the most common form of limb dysfunction (7.77%) reported in 3 studies. The incidence of hand dysfunction defined as disability, grip strength change, power loss or neuropathy was low at 0.49%. Although radial artery occlusion (RAO) was not a primary endpoint for this review, it was observed in 3.57% of the participants in a total of 8 studies included. The TFA group included 4 studies with 15,903,894 participants; the rates of peripheral neuropathy were 0.004%, sensory neuropathy caused by local groin injury and retroperitoneal hematomas were 0.04% and 0.17%, respectively, and motor deficit caused by femoral and obturator nerve damage was 0.13%. CONCLUSIONS: Limb dysfunction post cardiac catheterization is rare, but patients may have nonspecific sensory and motor complaints that resolve over a period of time.

Clinical significance of Angiopoietin-1 in Behcet's disease patients with vascular involvement.

Behcet's disease (BD) is a chronic multisystem inflammatory disorder of unclear etiology. Vascular inflammation, endothelial dysfunction and angiogenesis may be in part responsible for the pathogenesis of BD. Angiopoietin-1 (Ang-1) is a recent angiogenic mediator. The aim of the present study was to assess Ang-1 in the plasma of BD patients as well as to analyze its association with clinical, and laboratory parameters of the disease. The present study included 47 BD patients and 30 age- and gender-matched healthy controls. Demographic, clinical, disease activity and severity were prospectively assessed. Plasma Ang-1 levels were measured using enzyme-linked immunosorbent assay. The plasma level of Ang-1 in BD patients was significantly lower than healthy controls (p = 0.005). Plasma Ang-1 level in patients with vascular affection was significantly lower than those without vascular affection (p = 0.045). Levels of Ang-1 showed a significant positive correlation with steroid dose. Patients who received cyclophosphamide or steroids showed a significant increase in plasma Ang-1 level. This was further confirmed by the results of the multivariate analysis. There was no significant association between plasma Ang-1 levels and other clinical manifestations or disease activity and severity. Plasma Ang-1 levels were diminished in our BD patients especially in patients with vascular involvement. Larger studies with further investigations of the precise role of Ang-1 in the pathogenesis of BD are needed and might lead to novel therapies for the clinical management of BD.
