RESUMEN
AIM: Radial artery spasm is common during transradial procedures and is the most common cause of procedural failure. The objectives of this study were to assess whether the routine administration of sedation at the beginning of transradial coronary angiography with the use of hydrophilic-coated and smaller sheaths/catheters would reduce the incidence of radial artery spasm. PATIENTS AND METHODS: Patients undergoing transradial coronary angiography were prospectively randomized to receive midazolam during the procedure or no sedative treatment. The primary endpoint was angiographically confirmed radial artery spasm. Stenosis of the radial artery was measured with a computer-assisted quantification method. RESULTS: In all, 150 patients were randomized into a treatment group and a control group. Spasm occurred in 15 patients of the treatment group (20 %) versus 16 in the control group (21.3 %). There were no differences between the two groups regarding the incidence of spasm and the distribution of spasm severity (p > 0.05). No significant differences were observed between the two groups in terms of 30-day mortality or repeat hospitalization for any cause (p > 0.05). CONCLUSION: Routine use of midazolam could not reduce the occurrence of radial artery spasm during transradial coronary angiography.

AIM: The Ceraflex atrial septal defect occluder is an alternative device to the Amplatzer septal occluder with some structural innovations including flexible connection, increased flexibility, and minimized amount of implant material. We evaluated the efficiency and safety of the Ceraflex septal occluder device in percutaneous closure of secundum atrial septal defects. PATIENTS AND METHODS: This was a prospective, nonrandomized, multicenter study of patients undergoing transcatheter closure for an atrial septal defect with the Ceraflex and the Amplatzer septal occluder devices. A clinical evaluation and follow-up transthoracic echocardiography were performed at 1, 6, and 12 months. RESULTS: Between 2010 and 2014, 125 patients underwent atrial septal defect closure with the Ceraflex septal occluder (n = 58) and the Amplatzer septal occluder (n = 67) under transesophageal echocardiography guidance. Patient characteristics, the stretched size of the defect, device size, and fluoroscopy time were similar between the groups. The immediate and follow-up complete occlusion rates for both groups were 100%. There was no device embolization, procedure-related stroke, or pericardial effusion. CONCLUSIONS: The Ceraflex septal occluder is a safe and efficient device for closure of secundum atrial septal defects with no procedural complications. The Ceraflex has similar outcomes when compared with the Amplatzer septal occluder device. The advantage of the Ceraflex septal occluder device is that it can be deployed without the tension of the delivery catheter.

BACKGROUND: Prosthetic valve thrombosis (PVT) is serious complication of valvular replacement surgery, and increased levels of anticardiolipin antibodies (aCL) are associated with thrombosis. The aim of this study was to evaluate the role of aCL in the development of PVT. PATIENTS AND METHODS: We studied the aCL IgM and IgG levels in 114 patients with PVT and 80 healthy patients with prosthetic valves without PVT or a history of thrombosis. All patients underwent detailed transthoracic, transesophageal echocardiographic and clinical examinations. Blood samples were obtained after transesophageal echocardiography. Tests were repeated 12 weeks apart in patients with aCL IgM or IgG positivity. RESULTS: The mean age, sex, presence of atrial fibrillation and cardiovascular risk factors, elapsed time after surgery, and prosthetic valve type and location were similar between patients with PVT and those without. Ineffective anticoagulation was significantly higher among patients with PVT (p < 0.001). The aCL IgM values were significantly higher and positive (> 40 MPL) in the PVT group compared with the control group (10.58 ± 15.90 MPL to 3.70 ± 2.30 MPL, p < 0.001; 7.0 to 0 %, p = 0.016, respectively). The aCL IgG values were significantly higher and positive (> 40 GPL) in the PVT group compared with the control group (12.04 ± 17.58 GPL to 3.83 ± 2.56 GPL, p < 0.001 and 7.9 to 0 %, p = 0.01, respectively). According to international consensus documents, 16 patients had antiphospholipid syndrome. Ineffective anticoagulation and aCL IgM and IgG positivity were independent predictors of PVT in logistic regression analysis (multivariate r(2)= 0.648; p < 0.001, OR= 21.405, 95 %CI= 8.201-55.872; p = 0.008, OR= 1.322, % 95CI= 1.076-1.626; p = 0.005, OR= 1.288, 95 %CI= 1.079-1.538). CONCLUSION: Since the presence of aCL IgM and IgG positivity may cause a tendency toward PVT, these values should be examined in all patients with PVT.

We present the cases of two adult patients with cor triatriatum due to left atrial membrane with atrioventricular septal defect and right atrial membrane. Two-dimensional and real-time three-dimensional transthoracic echocardiography were performed. These noninvasive modalities provided a comprehensive anatomic and hemodynamic evaluation of the anomaly.

We report on a 37-year-old patient who suffered from myocardial stunning after exposure to carbon monoxide, despite having normal coronary arteries. As myocardial ischaemia may be asymptomatic in these patients, close monitoring with serial electrocardiography and of serum cardiac enzymes and troponins is recommended.
