Right coronary artery originating from left anterior descending artery: a case report

Right Coronary Artery (RCA) originating from left anterior descending artery is a very rare congenital coronary artery anomaly. A 66-year-old man presented with hypertension and complaints of exertional chest pain. The angiography was performed. Aortic root angiography showed no coronary ostium orginating from the right sinus of valsalva. Right coronary artery was vizualized as anomalously originating from the midportion of left anterior descending artery. Severe stenosis were seen in ostium of anomalous right coronary artery, in midportion of left anterior descending and in midportion of circumflex artery. The patient was referred for coronary artery bypass grafting. The patient underwent coronary artery bypass surgery for three vessels. He was discharged home on postoperative day 7 without any complication. His echocardiogram on follow-up visit revealed good biventricular function

Right coronary system grafts: alone or together with left system grafts--angiographic results.

The aim of this study is to compare the long-term graft patency between patients who had sequential or individual right posterior descending artery (RPDA) anastomosis.Two hundred and forty-two patients underwent coronary artery bypass grafting (CABG) between June 1994 and December 2003. They were examined retrospectively with respect to coronary angiograghic data. [Group 1] Individually right system grafts in RPDA position (n=139). [Group 2] RPDA anastomosis sequentially with left system (n=103). Patency rates for posterior descending arteries in each group were separately calculated for each vessel quality category.The mean interval from operation to angiography was 50.6+/-48.9 months in group 1 vs 57.5+/-39.2 months in group 2 respectively. The overall patency rate was 66.2% (92/139) in group 1 and 78.6% (81/103) in group 2 (p=0.04). When the RPDA has good run-off capacity, the patency rate was 69.1% in group 1 and 85.2% in group 2.When the RPDA has good run-off capacity, snake grafts show excellent results and right and left coronary systems could be anastomosed sequentially

Operative and early results of coronary artery bypass grafting in female patients in different body mass indexes

<p>Abstract</p> <p>Background</p> <p>Female gender has been reported to be an independent risk factor for coronary artery bypass grafting (CABG) in European System for Cardiac Risk Evaluation. The effect of the body size on the CABG outcome is less clear. There is ongoing debate about obesity as a risk factor for adverse outcomes after cardiovascular procedures. The goal of this retrospective study is to evaluate the in hospital and early postoperative outcomes in severe obese, obese and normal-slightly obese female patients after CABG.</p> <p>Methods</p> <p>In a four year period a total of 427 female patients underwent isolated CABG under cardiopulmonary bypass. The patients were allocated into three groups according to the Body Mass Index (BMI) as follows; group 1: severe obese patients; BMI > 35, group 2: obese patients; 30≤BMI≤35, group 3: normal-slightly obese patients; BMI < 30</p> <p>Results</p> <p>The patients in group 3 were older than the group1 and group 2 (65,6 ± 8,3 year vs 63,01 ± 8,0 and 63,57 ± 8,4 year p < 0,05). In group 1 diabetic patients were more than in group 2 and group 3 respectively (54,4% vs 43,4% and 40%, p < 0,05). Urgent operation was more in group 1 than in group 2 and 3 respectively (37,6% vs 17,2% and 21,2% p < 0,05). The patients in group 3 had significantly greater postoperative drainage at 24 h compared with values in group 1 and group 2 (647 ± 142 ml vs. 539 ± 169 ml and 582 ± 133 ml, p < 0,05). Mortality rate in group 1 was 0,8%, 0% in group 2 and 1,2% in group 3 respectively. Wound problem has occured in 41 patients (9,6%).The percentage of postoperative wound problems was higher in group 1 but did not show statiscially difference. Following discharge a total of 43 (10,1%) patients re-hospitalized within 30 days. Re-hospitalization rate was 16,1% in group1, 9,8% in group 2 and 6,5% in group 3 (p < 0,05).</p> <p>Conclusion</p> <p>This study may give an aspect for evaluations of the inhospital-early mortality and morbidity after CABG in female patients in different BMI. Severe obesity is not a risk factor in-hospital mortality in female patients. However, severe obese female patients appear to have more wound problems and re-hospitalization rate after CABG compared to obese and normal-slightly obese patients.</p
