Congenital Coronary Anomaly

Background: Single coronary ostium concomitant with coronary artery fistula is a very rare congenital anomaly. Apart from that, the combination of a closed loop of the coronary artery has never been reported.Case presentation: Herein, we present a 7-year-old girl diagnosed as single left coronary ostium with a giant coronary trunk, coronary artery to right ventricle fistula, and coronary artery ring. The coronary fistula was surgically ligated with off-pump strategy and the patient discharged on postoperative day 5 and free of symptoms during the 3 years of follow-up.Conclusion: To our knowledge, the presented congenital coronary anomaly is the first to be reported in the literature with the name of congenital coronary artery ring with single left coronary ostium and fistula.

<p><b>Objectives:</b> Despite increasing recognition that off-pump coronary artery bypass surgery and sequential grafting strategy individually are associated with improved outcomes, concerns persist regarding the safety and efficacy of combining these 2 techniques. We compared in-hospital and midterm outcomes for off-pump multivessel sequential and conventional coronary artery bypass grafting.</p><p><b>Methods:</b> From September 1998 to September 2008, 689 consecutive patients received off-pump multivessel sequential coronary artery bypass grafting performed by a single surgeon. These patients were propensity matched to 689 patients who underwent off-pump coronary artery bypass grafting without sequential anastomoses. A retrospective analysis of prospectively collected perioperative data was performed. In addition, medical notes and charts of all the study patients were reviewed. The mean duration of follow-up was 5.1 � 2.0 years.</p><p><b>Results:</b> The major in-hospital clinical outcomes in the sequential and control groups were found to be similar. After adjusting for clinical covariates, sequential grafting was not an independent predictor of in-hospital adverse events (odds ratio [OR], 1.18; 95% confidence interval [CI], 0.86-1.50; <i>P</i> = .31), medium-term mortality (hazard ratio [HR], 1.26; 95% CI, 1.06-1.32; <i>P</i> = .92), and readmission to hospital (HR, 1.12; 95% CI, 0.96-1.20; <i>P</i> = .80). Sequential grafting was an independent predictor of receiving more than 3 distal anastomoses (OR, 7.46; 95% CI, 4.27-11.45; <i>P</i> < .0001). Risk-adjusted survival was 89% for sequential grafting patients and 88% for conventional grafting patients (<i>P</i> = .96) during the medium-term follow-up.</p><p><b>Conclusion:</b> Our analysis confirms the short- and midterm safety and efficacy of off-pump sequential coronary artery bypass grafting.</p>

Introduction Multivessel coronary artery bypass graft (CABG) with bilateral internal thoracic arteries (BITA) has only been uncommon and technically demanding. We describe our experience with BITA only CABGs requiring ≥ 4 anastomoses. Material and Methods The department's database was queried for patients undergoing isolated CABG with ≥ 4 anastomoses. The surgical technique included systematically a right internal thoracic artery (ITA) of left ITA Y graft. The multivariate model included variables with a p < 0.3 at univariate analysis. Results Between January 2006 and December 2009, 251 consecutive patients (71 ± 10 years) (on-pump: 130, off-pump: 121) had CABG with ≥ 4 anastomoses, representing 21% of total isolated CABGs for the same period; all patients received a totally arterial BITA only revascularization. Follow-up was 4.9 ± 1.6 years. Overall and cardiac cumulative survivals were 78 and 92%, respectively, at 5 years. The occurrence of any major postoperative complication was associated with overall and cardiac mortality (odds ratio [OR]: 3.6, 95% confidence interval [CI]: 1.3–9.9 and OR: 5.4, 95% CI: 1.3–21.9, respectively). Major sternal wound complication requiring surgical revision was not associated with impaired glucose control (n = 9; diabetics: 6/82, 7.3%; nondiabetics: 3/169, 1.8%, p = 0.06). Preoperative kidney failure was associated with incomplete revascularization (OR: 6.2; 95% CI: 1.2–33.5), that was unfailingly due to ungraftable right coronary artery targets. Discussion BITA only revascularization was a valuable and safe procedure, with favorable results in terms of morbidity and mortality at a 5 years' follow-up.

Left coronary ostial stenosis, which is associated with sudden death, occasionally occurs in individuals with Williams syndrome. However, surgical methods that provide reliable long-term revascularization remain unknown among infants and young children with coronary ostial stenosis. We describe the case of an 18-month-old boy with Williams syndrome who presented with cardiogenic shock due to left coronary ostial stenosis. We performed patch augmentation of the left coronary ostium using glutaraldehyde-treated autologous pericardium. At the last follow-up, the patient was well without any adverse events or myocardial ischemia.

Anterolateral Wall

Background Dyskinetic areas of the lateral and inferior left ventricular (LV) wall are frequently encountered in patients with coronary artery disease. In clinical practice, all of the techniques described for the restoration of shape and function of the LV require cardiopulmonary bypass. A new technique of LV external reshaping that aims to obtain a near-normal ventricular conical shape is described. This technique is performed during an off-pump coronary artery bypass graft (CABG) operation. It is used mainly on the inferior and lateral walls of the ventricle, but also on the anterolateral wall when warranted. This technique can be considered an alternative to classic aneurysmectomy in high-risk cases. Methods All patients underwent total arterial revascularization without aortic manipulation. Intraoperative transesophageal echocardiography was used in all cases to define the dilated akinetic/dyskinetic area. This area was effectively plicated using interrupted mattress sutures reinforced with Teflon felt or pericardial strips. This technique allows near normalization of the geometry of the ventricle and LV end-diastolic volume reduction. In cases of preexisting mitral regurgitation (MR), a reduction of the MR was observed after lateral wall restoration. From September 2002 to April 2005, the external reshaping technique was applied on 56 cases among 949 off-pump CABG cases (5.9%). A detailed transthoracic echocardiogram was obtained preoperatively. The mean ejection fraction of all enrolled patients was 31.2 ± 7%. The location of the plication was: lateral wall in 22, inferior wall in 16, and anterolateral wall in 18. The average number of coronary anastomoses was 2.6. Twelve patients were found to have 2–3 + MR. All patients were followed up during a period of 35 months. Results One patient died due to severe right ventricular dysfunction. Seven patients developed atrial fibrillation, and one had ventricular tachycardia. During the follow-up period, we observed a reduction of left ventricular end-diastolic diameter and a parallel augmentation of ejection fraction (mean 42.2 ± 4%). The ventricular cavity's architecture was normalized. Among the 12 patients with MR, an improvement of regurgitation was noted in 10 (from 2–3+ to 1–2+). One patient died during the follow-up period, and 1 patient required reoperation due to persistent severe MR. Conclusions The external reshaping of the LV during beating heart surgery is technically feasible, has promising results, and can be performed without major complications.

Abstract Background Isolated coronary arteriovenous fistulas are extremely rare, accounting for 0.08–0.4% of all congenital heart disease. Closure of the fistula is recommended in cases of large dimensions, relevant left–right shunt, or ischaemic events. Thrombosis of the coronary aneurysms may occur as a postoperative complication. Case summary We report a case of a coronary fistula between the circumflex artery and coronary sinus with giant aneurysm. After a failed percutaneous closure attempt, the patient was surgically treated without major postoperative complications. Despite therapeutic anticoagulation and antiplatelet therapy, she presented at clinical follow-up with thrombosis of the dilated coronary artery without signs or symptoms of ischaemia. Discussion Management of coronary artery fistula may be challenging in cases in which initial percutaneous closure is unsuccessful. This particular case also highlights the importance of close follow-up, despite optimal therapy, to detect potentially lethal complications related to the low flow in the dilated coronary aneurysm.

A 14-year-old boy was diagnosed with an anomalous left coronary artery coursing between the ascending aorta and the main pulmonary artery and associated with a single coronary ostium. Owing to the high risk of sudden cardiac death, surgery was performed although he was asymptomatic with no sign of myocardial ischemia. Reimplantation of an anomalous left coronary artery is generally considered difficult because an aortic cuff is unavailable for coronary anastomosis; however, we accomplished a successful direct reimplantation in this patient. This procedure offers another choice in the surgical treatment of anomalous left coronary artery.
