RESUMEN

Although the majority of coronary artery anomalies are found incidentally and not clinically significant, the interarterial course between the major vessels of the aberrant artery may be responsible for syncope, angina, arrhythmias or sudden death. There are only a few case reports describing the origination of all the coronary arteries from a single ostium. This anomaly occurs in only 0.024%-0.044% of the population. Left coronary artery originating from the right coronary is a rare coronary abnormality. Here we report a case of acute myocardial infarction in a patient with anomalous left coronary artery originating from the right coronary artery, as was confirmed by computerized tomography angiogram, which showed that only one single coronary artery stem originating from the right sinus of Valsalva trifurcated into a right coronary artery, left circumflex artery and a hypoplastic left anterior descending artery. Subsequent percutaneous coronary intervention (PCI) procedures were performed successfully. PCI procedures should be carried out with great caution in such cases, and this condition should be managed as a left main lesion.

RESUMEN

<p><b>OBJECTIVE</b>To assess the efficacy and safety of two arterial closure devices, Angioseal and Perclose, in patients undergoing coronary angiography and invasive interventions.</p><p><b>METHODS</b>From January 2001 to April 2011, 997 inpatients underwent coronary angiography and interventions with arterial closure using Perclose (486 cases) or Angioseal (511 cases). The time to ambulation and hemostasis, major vascular complications and deployment success rate with the two devices were compared.</p><p><b>RESULTS</b>The time to hemostasis was significantly shorter in Angioseal group than in Perclose group (3∓0.9 min vs 10.8∓4.8 min, P<0.001), but the time to ambulation was comparable between the two groups (6.4∓1.2 h vs 6.3∓0.7 h, P>0.05). The incidences of vascular complications showed no significant differences between the two groups (4.5% vs 3.7%, P>0.05), and none of the cases in either group developed femoral artery thrombosis or low limb embolism following the procedures. The deployment success rate was comparable between the two groups (97.8% vss 98.6%, P>0.05), and deployment failure was associated mainly with mishandling and design defect of the devices.</p><p><b>CONCLUSIONS</b>Angioseal and Perclose are both effective and safe for arterial closure with reduced hemostasis and ambulation time and low incidences of vascular complications. Angioseal appears to have better performance than Perclose in shortening the hemostasis time and is easier to handle.</p>
