1/15. Diagnosis of a left coronary artery to right ventricular fistula with progression to spontaneous closure.Coronary artery fistulas in structurally normal hearts are rare. The natural history of these lesions depends on their size and can cause congestive heart failure, infective endocarditis, ischemia, or accelerated atherosclerosis. These fistulas are usually closed either in the catheterization laboratory or surgically. This case demonstrates the prenatal diagnosis of a left coronary to right ventricular fistula and documents its natural history to spontaneous closure by 1 year of age. This may help confirm the rationale of observation rather than closure of small fistulas in selected cases of patients without symptoms.- - - - - - - - - - ranking = 1keywords = catheterization (Clic here for more details about this article) |
2/15. Aortic dissection complicated with aorto-right atrium fistula.Aorto-right atrium fistula associated with aortic dissection is a very rare complication. Here report a case of successful surgical repair of ascending aortic dissection complicated with aorto-right atrium fistula. A 65-year-old man was presented with sudden chest pain and dyspnea. Fifteen years ago, he had aortic valve replacement. An aortic dissection with fistula to the right atrium was diagnosed by echocardiography and cardiac catheterization. At operation, dense adhesion of the aortic root due to the previous cardiac operation was confirmed, and this was suggested as the cause for this rare complication.- - - - - - - - - - ranking = 1keywords = catheterization (Clic here for more details about this article) |
3/15. Percutaneous closure of coronary pulmonary arterial fistula using catheterization laboratory trash.We report a case of coronary pulmonary arterial fistula that was successfully occluded by packing the fistula with thrombogenic floppy tips of used percutaneous transluminal coronary angioplasty guidewires instead of conventional steel coils.- - - - - - - - - - ranking = 4keywords = catheterization (Clic here for more details about this article) |
4/15. Delayed presentation of injury to the sinus of valsalva with aortic regurgitation resulting from penetrating cardiac wounds.A 39-year-old man had attempted to commit suicide using a small knife to penetrate the anterior chest wall. An emergency operation was performed successfully to repair the penetrating cardiac injury of the right ventricular outflow tract without using cardiopulmonary bypass. Two years after the operation, he was complained of dyspnea and a continuous murmur was detected. echocardiography and cardiac catheterization revealed aorto-right ventricular fistula in the sinus of valsalva with aortic regurgitation. In operation, the healed laceration of the right coronary cusp and the fistula between aorta and right ventricle were identified. The fistula was closed using a Dacron patch and the aortic valve was replaced with a mechanical valve. Long-term follow-up of penetrating thoracic injuries is important for detecting underlying intracardiac lesions.- - - - - - - - - - ranking = 1keywords = catheterization (Clic here for more details about this article) |
5/15. myocardial ischemia and congestive heart failure from a left main to coronary sinus fistula.A coronary artery fistula (CAF) is a rare congenital anomaly first reported by Krause in 1865. It is defined as a direct communication between the coronary artery and any surrounding cardiac chamber or vascular structure, which bypasses the myocardial capillary bed. The incidence of small CAFs in an adult population, undergoing cardiac catheterization at the Cleveland Clinic, was 0.13%. In the same series, the incidence of large or multiple fistulas was less than that of small fistulas and was present in 0.05% of all patients screened. The natural history of CAF in adults remains undefined, as does the best approach to managing these patients with recommendations for early closure as well as conservative management found in the medical literature. We present a patient initially diagnosed with a clinically silent CAF who presents 10 years later with symptoms and many of the classic findings of a CAF. An alternative model for the management of CAF in adults is discussed.- - - - - - - - - - ranking = 1keywords = catheterization (Clic here for more details about this article) |
6/15. Coronary artery fistula presenting as bacterial endocarditis.Coronary artery fistula is often considered to be a benign and rare congenital anomaly. It is usually an incidental finding encountered during routine cardiac catheterization. We report a case of a patient presenting with endocarditis involving a large coronary artery fistula connecting an aneurysmal circumflex coronary artery to the coronary sinus. The diagnosis was initially made by echocardiography and confirmed by cardiac catheterization. In addition, we briefly discuss the literature on management of this coronary anomaly.- - - - - - - - - - ranking = 2keywords = catheterization (Clic here for more details about this article) |
7/15. A case of sinus of valsalva-right ventricle fistula without a typical aneurysm, and a single origin of the coronary arteries.Few previous reports have described a sinus of valsalva fistula without an aneurysm in Japanese patients. A single origin of the coronary arteries is a rare coronary anomaly. We describe a 75-year-old woman with a single origin of the coronary arteries and a sinus of valsalva fistula without a typical aneurysm. echocardiography showed turbulent flow from the right coronary sinus of valsalva to the right ventricle throughout the cardiac cycle. aortography confirmed the presence of a right coronary sinus of valsalva-right ventricle shunt jet. echocardiography and aortography demonstrated that there was no deformity of the sinus of valsalva. cardiac catheterization revealed that the left-to-right shunt rate was 29% and the Qp/Qs was 1.41. aortography and coronary angiography did not identify a right coronary artery originating from the right sinus of valsalva. coronary angiography revealed that the right coronary artery arose from the proximal part of the left anterior descending artery and did not detect significant organic stenosis of the coronary artery. She was diagnosed as having a sinus of valsalva to right ventricle fistula without an aneurysm, and a single origin of the coronary arteries.- - - - - - - - - - ranking = 1keywords = catheterization (Clic here for more details about this article) |
8/15. A rare case of pulmonary hypertension. As a result of arteriovenous fistula after cardiac surgery.A 19 year-old woman who underwent corrective surgery for an atrial septal defect (ASD) and ventricular septal defect (VSD) 12 years previously presented with pulmonary hypertension. cardiac catheterization showed a fistula between the right subclavian artery and vena jugularis interna. In this case, a rare example of secondary pulmonary hypertension due to acquired arteriovenous fistula after cardiac surgery is presented.- - - - - - - - - - ranking = 1keywords = catheterization (Clic here for more details about this article) |
9/15. Venobronchial fistula: an unusual complication of long-term central venous access.A venobronchial fistula developed between the azygous vein and the upper aspect of the right main bronchus 12 months after completion of the treatment of a stage IIIB non-small-cell lung cancer in a 54-year-old man. The fistula contained the tip of the catheter placed for chemotherapy perfusion. The reported case presented risk factors previously identified for such a complication. In addition, some clinical particularities were present, suggesting new potent risk factors and some preventive means for safe long-term central venous catheterization.- - - - - - - - - - ranking = 1keywords = catheterization (Clic here for more details about this article) |
10/15. rupture of an aortic dissection into the right atrium in a patient with a previous aortic valve replacement: a case report.We report the case of a 73-year-old man with a history of previous aortic valve replacement in 1990 and rupture of an aortic dissection into the right atrium. The patient was admitted to the emergency room because of chest pain, stopped not long after. The electrocardiogram did not show any signs of ischemia and myocardial enzymes were not increased. Transthoracic echocardiography revealed aortic root dilation (maximum diameter 60 mm) extended to the aortic arch, and the presence of a flow from the ascending aorta to the right atrium (evocative of a fistula between the two chambers). The aortic valvular prosthesis function was good. Transesophageal echocardiography confirmed an aorta-right atrium fistula. cardiac catheterization did not show any luminal obstructions in the coronary arteries; there was a small shunt from the aorta to the right atrium. The ascending aorta and the aortic root were replaced with a Dacron graft. Right and left sinuses were reimplanted to the graft. The fistula was repaired with 4-0 pledgeted Prolene sutures. The surgeon's diagnosis was "type A aortic dissection in a patient with an ascending aorta aneurysm and an old ascending aorta-right atrium fistula".- - - - - - - - - - ranking = 1keywords = catheterization (Clic here for more details about this article) |
