11/1214. Right ventricular myocardial bridge in a patient with pulmonary hypertension--a case report.Myocardial bridge is a not uncommon finding in routine diagnostic coronary angiography or pathological examination of the heart. It is almost always confined to the left ventricle and the left anterior descending coronary artery. This report describes a patient with chronic lung disease, severe left ventricular dysfunction, and pulmonary hypertension in whom coronary angiography revealed bridging of the right ventricular branch of the right coronary artery.- - - - - - - - - - ranking = 1keywords = artery (Clic here for more details about this article) |
12/1214. Anomalous coronary artery, aortic dissection, and acute myocardial infarction.The combination of acute coronary occlusion and aortic dissection because of involvement of one or other coronary vessels in the dissection flap is uncommon. Furthermore, the occurrence of an anomalous coronary artery and its involvement in acute myocardial infarction is even more uncommon. We describe a patient with acute myocardial infarction in whom an acute aortic dissection involved the ostium of an anomalous circumflex artery.- - - - - - - - - - ranking = 3keywords = artery (Clic here for more details about this article) |
13/1214. cesarean section in a mother with uncorrected congenital coronary to pulmonary artery fistula.PURPOSE: We report a case of a 33 yr old woman with pulmonary hypertension secondary to uncorrected right coronary artery to pulmonary artery fistula who underwent two successful operative deliveries under general anesthesia. CLINICAL FEATURES: This woman underwent an emergency Caesarean section at 32 wk gestation because she presented in NYHA Class IV, heart failure and premature labour. She did not have antenatal follow-up. For her second pregnancy, she was managed from the first trimester of pregnancy by the cardiologist, obstetrician and anesthesiologist. She received oral furosemide and digoxin from eight weeks gestation. pregnancy was managed to term before she progressed to NYHA Class IV and cardiac failure at 37 wk gestation. She had a Caesarean section under general anesthesia. She received rapid sequence induction of anesthesia and tracheal intubation with 0.1 mg x kg(-1) etomidate, 2 mg x kg(-1) succinylcholine and maintenance with nitrous oxide 50% in oxygen, isoflurane 1% and 0.1 mg x kg(-1) vecuronium. fentanyl, 2 microg x kg(-1) helped to obtund the hypertensive response to intubation. analgesia was provided with 1 mg x kg(-1) morphine. Glyceryl trinitrate infusion, 10-30 microg x min(-1) was used in addition to the anti-heart failure therapy. End-tidal capnography, electrocardiogram, pulse oximetry, continuous arterial blood pressure and pulmonary arterial catheter provided hemodynamic monitoring. The lungs were mechanically ventilated for 24 hr postoperatively. She received anti-heart failure therapy which she continued after discharge. She was NYHA class II upon discharge. She defaulted from further follow-up. CONCLUSION: Although the literature advocates, in this situation, controlled vaginal delivery utilising epidural analgesia, we describe the successful outcome for operative delivery under general anesthesia in a patient with secondary pulmonary hypertension and heart failure.- - - - - - - - - - ranking = 3keywords = artery (Clic here for more details about this article) |
14/1214. Use of navigator-echo-gated MRI to diagnose a coronary shunt involving an anomalous origin of the right coronary artery from the pulmonary artery.Origin of the right coronary artery from the main pulmonary artery is an anomaly that can cause formation of a left-to-right coronary shunt, leading to myocardial ischemia and early onset of congestive heart failure. We describe a case in which magnetic resonance imaging was able to show the anomalous origin of the right coronary artery, and magnetic resonance phase velocity mapping was able to demonstrate the presence of a left-to-right shunt through the coronary artery by showing retrograde flow in the right coronary artery.- - - - - - - - - - ranking = 6.5keywords = artery (Clic here for more details about this article) |
15/1214. Dual anterior interventricular arteries.A patient with dual left anterior descending (R. interventricularis anterior of the left coronary artery) coronary artery is presented. A normally arising left anterior descending was hypoplastic, and an anomalous left anterior descending, which arose from the right sinus aorticus had a normal caliber. The anomalous left anterior descending artery traversed between the aorta and the pulmonary artery supplying most of the anterior myocardial wall of the left ventricle. This rare coronary anomaly can potentially have implications on percutaneous coronary interventions or on surgical revascularization procedures.- - - - - - - - - - ranking = 2keywords = artery (Clic here for more details about this article) |
16/1214. Catheter-based techniques for closure of coronary fistulae.This study details different methodologies of percutaneous closure of arteriosystemic and arteriovenous coronary fistula. Seven patients underwent transcatheter intervention of 10 fistulas, with 7 fistulas successfully closed: 6 with embolic coil devices and 1 with a covered stent obstructing the fistula ostium. The major complication encountered was one death as a result of device recoil into a major epicardial vessel. Percutaneous transcatheter closure of coronary fistulas appears to be simple, facile, and effective. However, device recoil into an undesired arterial segment, while irritating in a noncoronary arterial tree, may be catastrophic when occurring in an epicardial coronary artery.- - - - - - - - - - ranking = 0.5keywords = artery (Clic here for more details about this article) |
17/1214. Successful closure of coronary-bronchial artery fistula with vein graft-coated stent.A coronary-bronchial fistula and aneurysmal dilatation of the proximal part of the fistula was successfully closed using an autologous vein graft-coated stent (Palmaz-Schatz stent). This is the first report that demonstrates the feasibility of the vein-coated stent for the treatment of congenital disease.- - - - - - - - - - ranking = 2keywords = artery (Clic here for more details about this article) |
18/1214. Malignant ventricular arrhythmias revealing anomalous origin of the left coronary artery from the pulmonary artery in two adults.We report two cases of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA), revealed by malignant ventricular arrhythmias in adult patients. A two coronary system was re-established in both patients, and cryotherapy was performed on one of the patients who, in addition, presented ventricular aneurysm triggering ventricular tachycardia.- - - - - - - - - - ranking = 5keywords = artery (Clic here for more details about this article) |
19/1214. Intralobar pulmonary sequestration supplied by the right coronary artery.Bronchopulmonary sequestrations are malformations that are often congenital; they consist of isolated nonfunctioning lung segments having no communication with functional tracheobronchial elements of the surrounding lung. They are supplied by single or multiple branches from the distal thoracic or proximal abdominal aorta, or from the celiac, splenic, intercostal, subclavian, or pulmonary artery. Due to the absence of ventilation, the lung tissue can become chronically infected. We describe an intralobar pulmonary sequestration with arterial supply from the right coronary artery.- - - - - - - - - - ranking = 3.0032527680531keywords = artery, single (Clic here for more details about this article) |
20/1214. Anomalous origin of a coronary artery in a transplanted heart.Upon routine coronary angiography one year after surgery in a 62-year-old male recipient of a heart transplant, an abnormal origin of the left anterior descending coronary artery from the pulmonary artery was found in the donor heart. This very rare congenital anomaly had not been detected during harvesting and transplantation of the heart, and to our knowledge it has never been described before in a heart transplant patient. The donor was a 43-year-old male who died of a spontaneous intracranial bleeding. The recipient continues to enjoy a normal functional capacity and is free of anginal complaints, though there is evidence of ischaemia in the left anterior descending artery territory on exercise thallium-201 myocardial perfusion imaging.- - - - - - - - - - ranking = 3.5keywords = artery (Clic here for more details about this article) |
