OBJECTIVES: With the increasing use of multi-detector CT, the number of detected cases with coronary-to-pulmonary artery fistula (CPAF) has increased. Several previous studies reported severe cases of angina, but no appropriate tests to evaluate myocardial perfusion for patients with CPAF have been established. We evaluated the hemodynamic characteristics of CPAF using thallium-201 (Tl-201) single photon emission computed tomography (SPECT). MATERIALS AND METHODS: Tl-201 SPECT was performed in 17 patients with CPAF, but without evidence of coronary artery disease on coronary computed tomography angiography (CCTA) (age, 58...

Coronary-cameral fistulas are relatively rare communications arising within the coronary vasculature entering into one of the four cardiac chambers. This case highlights a striking angiographic example of coronary-cameral fistula occurring after septal myomectomy, a complication occurring somewhat frequently with typical spontaneous resolution.

PURPOSE: In some patients, both an electrophysiological examination (EPS) and a coronary angiography (CA) are necessary. It might be preferable to choose a combined approach of EPS and CA versus performing them consecutively. The purpose of this study is to evaluate the type and rate of adverse events between both approaches. METHODS: Patients were eligible if they underwent a CA and an EPS in a combined approach or in a time interval of at most 2 months. In all patients, clinical adverse events were recorded...

A 53-year-old diabetic male with sternal dehiscence presented with recurrent staphylococcus bacteremia 2years after coronary artery bypass grafting (CABG). He was found to have a giant right coronary artery (RCA) pseudoaneurysm and a coronary cameral fistula on imaging. Due to excessive surgical risk, the patient underwent percutaneous treatment with a 5mm Amplatzer vascular plug 4 (St. Jude Medical, St.Paul, MN). Post-procedure imaging showed successful cessation of flow into the pseudoaneurysm and follow-up CT scan demonstrated significant improvement in the size of the pseudoaneurysm...

Coronary to pulmonary artery fistulas (CPAFs) are abnormal communications between the coronary and pulmonary arteries. They are an uncommon congenital heart disease and usually remain asymptomatic until later in life. However, there is no consensus on their management. We present four adult patients who required surgery for coronary to pulmonary artery fistulas to illuminate this issue. The clinical presentations were variable depending on the anatomical features of coronary to pulmonary artery fistulas and the presence or absence of other cardiac diseases...

The transfemoral arterial approach is used to gain access for angiography, percutaneous coronary interventions, or various endovascular therapies. To decrease the risk of procedure-related vascular complications, it is recommended to puncture the common femoral artery in its middle segment. However, due to inadequate access or anatomical variability, various complications, including hematoma, pseudoaneurysm, arteriovenous fistula, thrombosis, or dissection, can occur after transfemoral arterial interventions...

An aorta-to-right atrium (RA) fistula is an anomalous communication between the ascending or descending thoracic aorta and the RA. In this report, we describe a case of an idiopathic aortic root-to-RA fistula occasionally found during a coronary angiography performed in a young patient admitted for acute chest pain with evidence of multivessel coronary artery disease. The anatomical peculiarity of this fistulous communication is that it gave origin to collateral vessels furnishing the inferolateral wall of the left ventricle...

Herein, we report the case of a 44-year-old female with end-stage renal disease on hemodialysis. She was admitted to our hospital to evaluate if she was eligible for a kidney transplant. Transthoracic echocardiography showed a markedly dilated coronary sinus and an unexpected finding of increased right ventriculoatrial gradient. A saline contrast echocardiography to confirm the presence of persistent left superior vena cava (PLSVC) was not performed because of arteriovenous fistula (FAV) for hemodialysis on the left forearm...

RATIONALE: Cases of coronary artery fistula having a connection with the cardiac cavity are rare. Here, we report a case in which 2 coronary arteries empty into the left ventricular cavity together. PATIENT CONCERNS: A 63-year-old woman who was diagnosed as having hypertension 20 years prior presented with dyspnea. DIAGNOSES: The coronary angiography revealed coronary artery fistula. INTERVENTIONS: Chest X-ray showed pulmonary edema...

Introduction. Coronary artery stents are an uncommon site for infection. Only a handful of case reports describe this condition, and Staphylococcus aureus is the most frequent pathogen. Although rare, coronary stent infections are associated with a high mortality rate. Case presentation. We describe the case of a 50-year-old man with a past medical history of seven prior meticillin-resistant S. aureus (MRSA) infections over the previous 12 months, who presented with fever and was found to have persistent MRSA bacteraemia...

Congenital coronary-pulmonary artery fistulas complicated by continuity to a systemic artery and aneurysm are extremely rare. A 78-year-old woman was admitted to our hospital with a complaint of chest discomfort. Coronary angiography showed a coronary aneurysm and coronary-pulmonary artery fistula arising from the left circumflex artery and entering into the right lower pulmonary artery. Computed tomography angiography revealed a left subclavian artery-pulmonary artery fistula communicating with the coronary-pulmonary artery fistula...

Coronary complications in patients with transposition of the great arteries (TGA) after an arterial switch operation (ASO) are relatively rare, but of all the possible postoperative adverse events, they are potentially the most dangerous. The fate of the coronary arteries, which are transplanted during the neonatal ASO, remains uncertain. There is also no consensus regarding their postoperative evaluation, especially in asymptomatic patients. The aim of this study was to present the early results of routinely performed coronary computed tomography angiography (CCTA) in asymptomatic adolescents and young adults with TGA after an ASO...

Coronary artery anomalies represent a disease spectrum from incidental to life-threatening. Anomalies of coronary artery origin and course are well-recognized in human medicine, but have received limited attention in veterinary medicine. Coronary artery anomalies are best described in the dog, hamster, and cow though reports also exist in the horse and pig. The most well-known anomaly in veterinary medicine is anomalous coronary artery origin with a prepulmonary course in dogs, which limits treatment of pulmonary valve stenosis...

Aims: The relationship between echocardiographic measures of left ventricular (LV) systolic function and reference-standard measures have not been assessed in children. The objective of this study was to assess the validity of echocardiographic indices of LV systolic function via direct comparison to a novel composite measure of contractility derived from pressure-volume loop (PVL) analysis. Methods and results: Children with normal loading conditions undergoing routine left heart catheterization were prospectively enrolled...

Pulmonary atresia with intact ventricular septum (PA/IVS) is a rare right-heart obstructive lesion with a wide anatomic and physiologic spectrum of disease, ranging from simple membranous pulmonary valve atresia with a fully developed right ventricle (RV) to a severely hypoplastic RV and ventriculocoronary (RV-coronary) fistulas. Affected neonates are dependent on prostaglandin for adequate pulmonary blood flow. Depending on the severity of disease, treatment options range from transcatheter pulmonary valve perforation and ultimate biventricular repair to staged single-ventricle palliation...

Coronary artery fistulas (CAFs) are found in 0.3-0.8% of patients who undergo coronary angiography. CAFs are defined as single or multiple, small or large direct communications that arise from one or more coronary arteries and enter into one of the four cardiac chambers or major vessels. We present two cases of multiple coronary artery fistulas arising from diagonal and left anterior descending (LAD) branches of left coronary artery draining into the left ventricle. In both the cases, No intervention was performed...
