RESUMO
Distal radial artery access (DRA) is recommended as the preferred approach over the traditional proximal radial artery access (TRA) for coronary procedures; however, there are limited randomized controlled trials (RCTs) that compared the 2. We conducted an updated meta-analysis of all RCTs from inception to July 26, 2021, that compared DRA versus TRA in patients who underwent coronary procedures. The statistical analysis was performed using a random effect model to calculate risk ratios (RRs) with 95% confidence intervals (CIs). A total of 5 RCTs were included with a total of 1,005 patients. A pooled analysis of the data showed that the rate of successful cannulation was similar between the 2 arms (RR 0.85, 95% CI 0.68 to 1.07, p = 0.16, I2 = 94%). The rate of radial artery spasm significantly favored the DRA arm as compared with TRA (RR 0.51, 95% CI 0.34 to 0.75, p = 0.0007, I2 = 0%). Significantly more patients from the DRA arm required alternative arterial access. Moreover, the DRA group had an insignificantly decreased rates of radial artery occlusion (RR 0.24, 95% CI 0.05 to 1.20, p = 0.08, I2 = 46%) and early discharge after transradial stenting of coronary arteries access-site hematomas (RR 0.52, 95% CI 0.18 to 1.149, p = 0.22, I2 = 0%). The mean time for hemostasis was significantly shorter in the DRA arm (mean difference -6.64, 95% CI -10.37 to -2.90, p = 0.0005, I2 = 88%). In conclusion, DRA should be considered as a viable, effective, and safe arterial access method for patients who underwent coronary procedures.

INTRODUCTION: Primary cardiac tumors are rarely seen in the general population and only a subset are classified as cardiac papillary fibroelastoma. CASE PRESENTATION: A 59-year-old female that presented for unresponsiveness and cardiac arrest required 4 rounds of cardiopulmonary resuscitation and intubation. Laboratory investigations showed uncompensated respiratory acidosis, hyperkalemia, and elevated troponins. A chest computed tomography angiogram illustrated an acute right pulmonary embolism and a right atrial filling defect. Furthermore, an echocardiogram demonstrated a normal ejection fraction and a large, pedunculated, mobile, and non-valvular echodensity that was attached to the right atrium endocardium. Therefore, the patient was started on a heparin infusion and catheter-directed thrombolysis; however, the mass persisted. A surgical excision was performed, and a 40 mm was removed. The patient was diagnosed with a papillary fibroelastoma based on the clinical symptoms, imaging, and histological findings. CONCLUSION: This patient's papillary fibroelastoma had multiple rare features including right atrial origin, large size, non-valvular location, and developed symptoms. Although this disease can be initially fatal, the patients typically have a favorable prognosis after a successful excision.

OBJECTIVES: This study aimed to evaluate the efficacy and safety of personalized genotype-guided selection of antiplatelet therapy versus standard of care in patients undergoing percutaneous coronary intervention (PCI). BACKGROUND: Clopidogrel is the most frequently used P2Y12 receptor antagonist in patients with coronary artery disease. However, genetic variations of clopidogrel are associated with inter-individual response variability which could limit its efficacy. METHODS: Electronic databases were searched for all randomized clinical trials (RCTs) evaluating genotype-guided therapy versus standard of care in patients undergoing stent implantation. Aggregated risk ratios (RRs) and 95% CIs were calculated using a random-effects model. RESULTS: We included 6 RCTs with a total of 2,371 patients. When compared with standard of care, the use of genotype-guided therapy did not significantly reduce major adverse cardiovascular events (MACE) (RR 0.67; 95% CI: 0.35-1.27; P = 0.22). However, MACE was significantly reduced in the subset of trials which enrolled only acute coronary syndromes (ACS) (P < 0.01). In addition, there was a significant reduction in myocardial infarction in the genotype-guided group (RR 0.44; 95% CI: 0.28-0.70; P < 0.01; I2 = 0%). Other clinical outcomes were not significantly different: cardiovascular mortality (RR 0.68; 95% CI: 0.27-1.74; P = 0.42), stroke (RR 0.62; 95% CI: 0.23-1.65; P = 0.34), stent thrombosis (RR 0.37; 95% CI: 0.13-1.06; P = 0.06), and bleeding (RR 0.68; 95% CI: 0.43-1.06; P = 0.09). CONCLUSION: In patients undergoing stent implantation, MACE with genotype-guided therapy was not significantly reduced; however, there was a signal towards reduction of MACE in ACS patients, as well as a lower rate of MI, though this will require further confirmation in adequately powered trials.
