OBJECTIVES: We sought to determine differences in baseline characteristics and clinical outcomes in a consecutive series of patients undergoing arterial switch operation (ASO), assessing the effect of coronary anatomy on postoperative mortality, both overall and adjusted for surgical era. METHODS: From January 2000 to May 2015, 283 consecutive patients underwent ASO for transposition of the great arteries. A total of 103 patients (36.4%) had an associated ventricular septal defect and 23 (8...

Aims: Anomalous origin of a coronary artery from the opposite sinus (ACAOS) has been associated with adverse cardiac events in the young. It remains unknown whether this holds true for middle-aged patients with uncorrected ACAOS as well. We assessed the outcome in middle-aged patients with newly diagnosed ACAOS by coronary computed tomography angiography (CCTA) compared with a matched cohort. Methods and results: We retrospectively identified 68 consecutive patients with ACAOS documented by CCTA...

Objective Coronary artery dilations (CDs), a subgroup of coronary artery anomalies (CAAs), are relatively rare but important cardiac pathologies. They are considered to be linked to coronary atherosclerosis in most cases. Methods The demographic data, multi-slice computed tomographic coronary angiography data, coronary calcium score, and ascending aortic diameter (AAD) of 1538 patients were reviewed. In total, 197 (12.8%) patients (166 men, 31 women; age 15 - 84 years; mean 55.78 ± 12.32 years) with CAAs were identified, and 81 (5...

Persistent left superior vena cava (PLSVC) draining into coronary sinus is typically detected incidentally during transcatheter interventions utilizing left subclavian venous approach. In our experience, we have encountered this anomaly on a few occasions and in all these cases we successfully implanted leads in the right ventricle (RV) by shaping the stylet into a 'U-shaped' or 'pigtail shaped' curve. Herein, we report a case of an adult male who underwent successful dual chamber pacemaker implantation via PLSVC through left axillary venous approach...

A 77-year-old male presented with angina pectoris. On coronary angiography, the left anterior descending artery(LAD) was obstructed after branching the second septal branch. Three-dimensional (3D) images constructed with 64-slice computed tomography (CT) showed type I dual LAD. The short LAD, which had been erroneously recognized as a septal branch on coronary angiography, ran on the anterior interventricular sulcus (AIVS) where it then terminated. The long LAD, which was obstructed at its origin, ran on the left ventricular side of the AIVS, and entered the distal part of the AIVS...

Subrata Kar, Richard R Webel
Spontaneous coronary artery pseudoaneurysm (PSA, false aneurysm) is an extremely rare occurrence with the precise incidence unknown. It is defined as an outwardly bulging monolayer or double layer within the coronary artery that lacks all 3 layers (intima, media, and adventitia) of the arterial wall. Coronary PSA commonly occurs from arterial dissection or perforation induced by catheter intervention, infection, pregnancy, or trauma. Traumatic dissection or perforation of the coronary artery after a percutaneous coronary intervention (PCI) remains the most common cause...

The aim of this review was to describe recent advancements in the understanding of bicuspid aortic valve (BAV). BAV is the most common congenital cardiac anomaly, and affects between 0.46% and 1.37% of the population. There is a male predominance of approximately 3:1.While isolated BAV is found in certain patients, it is often associated with other congenital cardiac lesions, including dilatation of the thoracic aorta, coarctation of the aorta and abnormalities of the coronary anatomy. In most cases, it remains undetected until the patient contracts infective endocarditis, or calcification occurs...

BACKGROUND: Isolated coronary artery anomalies are usually clinically silent and mostly detected incidentally during angiography or autopsy. However, few of them may be implicated in cases of sudden cardiac death even in the absence of additional heart abnormalities. Prior knowledge of such variants and anomalies is necessary for planning various interventional procedures. Multiple detector computed tomography coronary angiography has proved a very useful non-invasive modality in this field given its superiority over conventional coronary angiography in providing detailed coronary artery anatomy...

The evaluation of the vast majority of children with anomalous aortic origin of a coronary artery (AAOCA) and/or myocardial bridges is performed with non-invasive testing. However, a subset of these patients may benefit from invasive testing for risk stratification. All patients included in the Coronary Anomalies Program (CAP) at Texas Children's Hospital who underwent cardiac catheterization were included. Techniques included selective coronary angiograms (SCA), intravascular ultrasound (IVUS), and fractional flow reserve (FFR) measurements with provocative testing using adenosine and/or dobutamine infusions...

The technique for successful surgical correction of an anomalous origin of the right coronary artery from the opposite aortic cusp with an aberrant course between the aorta and pulmonary artery is illustrated in a symptomatic 62-year-old woman. The intramural course of the right coronary artery traversed the tip of the commissure between the anterior and posterior leaflets, and its repair entailed unroofing of the intramural segment from inside the aortic intima. This technique required resuspension of the overlying commissure to maintain optimal aortic valve leaflet coaptation and prevent aortic insufficiency...

A 36-year-old woman was seen with complaints of exertional chest pain and shortness of breath. Her medical history included atrial fibrillation and diabetes. Physical examination was unremarkable except for an irregular cardiac rhythm. Myocardial perfusion imaging revealed the presence of a large area of infarction involving the entire anterior and apical walls and part of the anteroseptal wall with minimal periinfarct ischemia. Computed tomography coronary angiogram revealed an anomalous left main coronary artery arising from the main pulmonary artery...

The anomalous origin of the entire coronary system from the right coronary sinus is a very rare anomaly. Here a patient with this rare anomaly, who developed acute coronary syndrome, requiring revascularization, is presented and treated successfully. His coronary angiographic findings are also discussed. We would like to highlight the rarity of the origin of all 3 coronary arteries from a single coronary trunk. The case also highlights the importance of using Amplantzer AR1 guiding catheter for such anatomical variations arising in the right coronary cusp...

Dual left anterior descending coronary artery is a rare congenital anomaly with 4 subtypes. Double left anterior descending coronary artery originating from the left main stem and the right coronary artery (type IV dual left anterior descending artery) has been reported to occur in 0.01% to 0.7% of patients undergoing cardiac catheterization. We report a case of a 49-year-old woman who was found to have this anomaly during coronary angiography. The patient had been complaining of chest pain that mimics angina pectoris and exercise tolerance test was positive for myocardial ischemia...

Double right coronary artery (RCA) is an extremely rare coronary artery anomaly. We here report an atherosclerotic double RCA which appeared after primary percutaneous intervention performed to treat a 34-year-old male presenting with acute inferior myocardial infarction, cardiogenic shock and complete heart block. This is an unusual case as double RCA had been hidden by total atherosclerotic occlusion of the proximal part of the RCA and complete restoration of patency led complete heart block back to normal sinus rhythm...

A single coronary artery is one of the most rarely seen coronary artery anomalies. In addition, the specific subtype (Lipton RII-A) that our patient presented is one of the least common, and its clinical presentation as myocardial infarction and cardiac arrest has not been described in the literature. The case shows that although it is essential to exclude a malignant interarterial course of the vessel, cardiac arrest is a possible clinical presentation produced by myocardial ischemia in the context of acute myocardial infarction and should be managed according to clinical practice guidelines...

A dual left anterior descending (LAD) artery is an infrequent anomaly of the coronary circulation with rare variations that may cause symptoms. We report a 60-year-old man who underwent multiple percutaneous cardiac catheterizations with stent placements and presented with recurrent angina pectoris. Coronary computed tomographic angiography demonstrated a dual LAD with the long and short LADs originating from the right coronary artery and the left main coronary artery, respectively.

BACKGROUND: Coronary artery microfistulas are a rare anomaly; their association with hypertrophic cardiomyopathy is even rarer and can lead to serious cardiac complications owing to coronary steal phenomena such as angina pectoris, myocardial infarction, congestive heart failure, ventricular and supraventricular arrhythmias, syncope, and sudden death. CASE PRESENTATION: A 32-year-old Indian woman presented to our institute with severe angina on exertion and multiple episodes of pre-syncope...

Fragmentation of QRS complex (QRSf) is an easily evaluable, non-invasive electrocardiographic parameter that represents depolarization anomalies and that has been associated to several adverse outcomes such as sudden death, fibrosis, arrhythmic burden and worse prognosis in different conditions, including coronary artery disease (CAD). We present the case of a 69-year old male referred for study with symptoms of chronic stable angina. His electrocardiogram showed sinus rhythm, absence of Q waves, but the presence of QRSf in the inferior leads and V4-V6...
