The distal radial approach (DRA) is suggested to have benefits over the conventional radial approach (CRA) in terms of local complications and comfort of both patient and operator. Therefore, we aimed to compare the feasibility and safety of DRA and CRA in a real life population. We conducted a prospective, observational multicentric trial, including all patients undergoing coronary procedures in September 2019. Patients with impalpable proximal or distal radial pulse were excluded. Thus, the choice of the approach is left to the operator discretion. The primary endpoints were cannulation failure and procedure failure. The secondary endpoints were time of puncture, local complications and radial occlusion assessed by Doppler performed one day after the procedure. We enrolled 177 patients divided into two groups: CRA (n = 95) and DRA (n = 82). Percutaneous intervention was achieved in 37% in CRA group and 34% in DRA group (p = 0.7). Cannulation time was not significantly different between the two sets (p = 0.16). Cannulation failure was significantly higher in DRA group (4.8% vs 2%, p < 0.0008). Successful catheterization was achieved in 98% for the CRA group and in 88% for the DRA group (p = 0.008). Radial artery occlusion, detected by ultrasonography, was found in 3 patients in the CRA group (3.1%) and nobody in the DRA group (p = 0.25). The median diameter of the radial artery diameter was higher in the DRA than the CRA group (2.2 mm vs 2.1 mm; p = 0.007). The distal radial approach is feasible and safe for coronary angiography and interventions, but needs a learning curve.

The present study is in line with the general estimates in the world. It has revealed a high case of mortality among the patients awaiting corrective surgery. These children need more facilities.

IntroductionThe objectives were to assess the left ventricular (LV) structure and function in regularly trained young athletes, using 2 D conventional echocardiographic (echo) methods and speckle tracking echocardiography (STE). An observational cross-sectional study.MethodsThirty-three footballers and 20 healthy untrained subjects were included in the study. The systolic and diastolic LV functions were evaluated by 2D conventional echo parameters, Doppler method and STE.ResultsAll the found values were within the normal range. The LV End Diastolic Diameter (LVED 37.24±2.08 mm/m2) and the LV Mass index (LVMi 97.93±15.58 g/m2) were significantly higher in young athletes as compared with controls. There was no difference regarding the LV systolic function assessed by conventional echo parameters in the 2 study groups. Regarding the diastolic function, the transmitral inflow velocities ratio was significantly higher in athletes (E/A = 2.10±0.49 versus 1.64±0.26, p< 0.001) but there was no difference in the filling pressure in the 2 groups. The STE demonstrated a different pattern of LV deformation in the different groups. A significant lower LV global longitudinal strain (GLS -20.68±2.05 versus -22.99±2.32 %, p<0.001) and higher radial and circumferential strains have been found in the young athletes as compared with controls. A significant relationship between the GLS values and LVED (r= 0.299, p = 0.03) and LVMi was also reported in athletes.ConclusionWhile conventional morphological and functional echocardiographic parameters failed to distinguish the adaptations in the athlete’s heart, deformation parameters showed a different pattern of LV mechanics in young footballers versus controls.

Objective The purpose of the present study is to describe our experience with patients who have a transmural myocardial infarction (MI) in the presence of a normal coronary artery. The clinical profile, demographic characteristics and outcomes of these patients are discussed. Methods Between January 2006 and August 2011, 21 patients who presented with a Q-wave myocardial infarction were found to have normal coronary arteries. The prevalence rate of this entity was 1.5% (21 out of 1,400 Q wave MI patients). These patients were characterized by their young age (the mean age=44.95± 14.86), male dominance (90.47%), and a high prevalence of smoking (85.71%). In this study, 4 patients have an evident spontaneous spasm shown on coronary angiography which disappeared after intracoronary injection of nitrates. Coagulation Disorders, such as activated protein C resistance (APC) resistance, protein C deficiency and antiphospholipid antibody syndrome were found in 4 of 12 patients who underwent systematic examination. One patient had a history of lung cancer which may be associated with a hypercoagulable state and may explain the occurrence of myocardial infarction with a normal coronary artery. The mean left ventricle ejection was 56. 5±12. The mean follow-up was 24±10 months. Six patients developed residual chest pain which was generally easily controlled by anti-spastic therapy and no patient had a major cardiovascular event.Conclusion Patients with Q-wave MI and with normal coronary arteries seem to have a good short and long-term prognosis especially when they are treated with an exclusive medical strategy.
