coronary anomalies

Abraham Speedie, Cinosh Mathew, Rashmi Kerr, Rajneesh Calton
Coronary artery anomalies include anomalies of origin, termination, structure or course. Coronary artery fistulae (CAF) are classified as abnormalities of termination and are considered a major congenital anomaly. A coronary artery fistula involves a sizable communication between a coronary artery, bypassing the myocardial capillary bed and entering either a chamber of the heart (coronary-cameral fistula) or a great vessel. Bilateral coronary artery fistula, are a rare variant. We describe a bilateral CAF with angina and significant coronary artery disease requiring percutaneous coronary intervention...

OBJECTIVE: Relative ease of estimating of Ascending Aortic (AA) pressure non-invasively enables interpretation of age-related pressure waveform changes due to altered pulse wave propagation. AA flow velocity waveforms, measured invasively by ElectroMagnetic (EM) cuff/ catheter, and non-invasively by Cardiac Magnetic Resonance (CMR) also show characteristic aging changes attributable to aortic dilation and subtle impairment of Left Ventricular (LV) function. Conventional Doppler waveforms do not...

OBJECTIVES: To assess the natural history and outcome of fetal pulmonary stenosis [PS] detected at 14 to 16 weeks gestation. METHODS: This is a retrospective study, in the years 2004-2015, with serial follow up during pregnancy. Patients referred for complete early fetal ultrasound including all fetal systems and a fetal echocardiogram. Ninety seven percent of the women were low risk, and 3% had risk factors such as maternal type 1 diabetes mellitus, exposure to teratogenic drugs or anomalies in previous pregnancies or in other family members...

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is an extremely rare, potentially fatal, congenital anomaly with a high mortality rate in the first year of life. It occurs rarely in adulthood and may appear with malignant ventricular a rrhythmia or sudden death. We report a case of a 49-year-old woman with ALCAPA who presented with dyspnea on exertion. Management was coronary artery bypass grafting to the left anterior descending artery and obtuse marginal arteries, closure of the left main coronary artery ostium, and reestablishment of the dual coronary artery system...

A 47-year-old female presented to our hospital with symptoms of stable angina. Cardiac catheterization revealed a rare coronary artery anomaly of the left anterior descending (LAD) artery branching off the right coronary artery ostium. Furthermore, the anomalous LAD artery exhibited significant atherosclerotic obstruction. Our review of the literature found only nine such previously described cases. Due to the unique nature of coronary artery anomalies and their complications, we would like to contribute our case to the medical literature...

Certain congenital heart anomalies make patients more susceptible to arrhythmia development throughout their lives. This poses the question whether prophylactic arrhythmia surgery should be incorporated into reparative open heart procedures for congenital heart disease. There is currently no consensus on what constitutes a standard prophylactic procedure, owing to the questions that remain regarding lesions to be performed; energy sources to use; proximity of energy source or incisions to coronary arteries, sinoatrial node, atrioventricular node; circumstances for right atrial, left atrial, or biatrial appendectomy; and whether to perform a right, left, or biatrial maze procedure...

To assess management of non-syndromic dens evaginatus affecting permanent maxillary central incisor, we performed a systematic review and also present a case report. We searched PubMed via MEDLINE and the reference lists of included reports. Eligible studies were any type of clinical studies describing the management of non-syndromic dens evaginatus affecting the crown of a permanent maxillary central incisor. We included 31 studies corresponding to 34 relevant case reports. Therapeutic options were complete reduction of the talon cusp in a single appointment (56%), periodic and gradual reduction of the cusp (26%), abstention (13%) or extraction (5%)...

Congenital stenosis/atresia of a coronary artery is an exquisitely rare anomaly (Congenit Heart Dis, 2, 2007, 347) with increased risk of sudden death. Bilateral coronary obstruction is even more unusual but has been reported in conjunction with aortic valve disease, syphilis, and Takayasu's arteritis. To the best of our knowledge, obstruction of both coronaries in a pediatric patient has only been reported once (Ann Thorac Surg, 55, 1993, 1564). We present a patient with an intramural, anomalous aortic origin of the right coronary artery from the contralateral sinus (AAORCA) with near atresia of the left main coronary ostium...

Pulmonic stenosis (PS) is the most common congenital cardiac disease in dogs. Boxers and English bulldogs are among the most commonly affected breeds and also commonly associated with an aberrant coronary artery (CA). If an aberrant CA is suspected and balloon valvuloplasty indicated, an intra-operative angiography is recommended prior to the procedure. ECG-gated computed tomography (CT) can be used to screen for CA anomalies in a quick and minimally-invasive way (preventing side effects associated with selective catheter angiography) and allowing early planning of the procedure...

In the absence of other associated cardiac anomalies, single coronary artery (SCA) per se is a rare anomaly detected during coronary angiography or autopsy. Various types of SCA detected during coronary angiography have already been described. We herein report a type of SCA originating from the right sinus of Valsalva, with the right circumflex, left circumflex, and left anterior descending coronary arteries arising from the proximal part of the SCA in a 76-year-old female patient. She developed ventricular fibrillation during coronary angiography, which calls for caution while performing a coronary angiogram in such patients...

BACKGROUND: Kawasaki disease (KD) is the leading cause of acquired heart disease in children. Signal average electrocardiogram changes in patients during the acute phase of KD with coronary artery anomalies (CAA) include depolarization changes. We set out to determine if 12-lead-derived atrioventricular depolarization differences can identify CAA in patients with KD. METHODS: A blinded, retrospective case-control study of patients with KD was performed. Deep Q waves, corrected QT-intervals (QTc), spatial QRS-T angles, T-wave vector magnitudes (RMS-T), and a novel parameter for assessment of atrioventricular depolarization difference (the spatial PR angle) and a two dimensional PR angle were assessed...

We report a novel homozygous apolipoprotein A5 (APOA5) frameshift mutation (c.G425del-C, p.Arg143AlafsTer57) identified in a 12-year-old boy of Pakistani origin with severe hypertriglyceridemia (up to 35 mmol/L) and type V hyperlipoproteinemia. The patient did not respond to fibrate therapy, but his condition improved under a very low fat diet, although compliance was suboptimal. Heterozygous status was detected in both parents (consanguineous union) and one sibling, all showing moderate hypertriglyceridemia (between 5 and 10 mmol/L)...

Coronary artery aneurysm is a rare congenital or vascular inflammation-based anomaly for which the clinical course and optimal timing of treatment remain unclear. Here, we report a case of sudden death caused by a giant coronary artery aneurysm of the left anterior descending artery that presented with chest pain. This case suggests that urgent interventional or surgical repair is needed when a large coronary aneurysm presents with acute ischemic symptoms.

BACKGROUND: Congenital anomalies of the coronary arteries(CAs) are rare and are often diagnosed incidentally during a conventional coronaryangiography. Recently, the incidence of these congenital defects is on the rise particularly after the introduction of the electrocardiography (ECG) gated coronary computed tomographic angiography (CCTA). This innovative radiological screening modality has led to the most precise mapping of the course of the CAs on Computed Tomographic Scan. The aim of the study is to determine the prevalence and describe theCAscongenital anomalies and their variations in Kuwaiti population at a single institution experience...

BACKGROUND: Persistent left superior caval vein (PLSCV) is a rare, anatomically diverse developmental anomaly of systemic veins. Clinically asymptomatic PLSCVs are detected incidentally during medical procedures that utilize systemic veins, such as cardiac implantable electronic device (CIED) placement, and whose successful completion depends on favorable morphometric parameters of these vessels. The aim of this paper was to present topography and morphometry of PLSCV variations encountered during CIED implantation procedures...

Congenitally corrected transposition of the great arteries is a rare abnormality accounting for approximately 1% of clinically apparent congenital heart disease. Age at time of diagnosis and survival rate vary and depend on associated anomalies, including pulmonary stenosis, ventricular septal defect, atrial septal defect, atrioventricular block, and atrioventricular valve regurgitation. Reported cases of corrected transposition of the great arteries with single coronary ostium anomaly and atrial septal defect are very rare...
