[Surgical treatment of coronary artery to pulmonary artery fistula with a saccular aneurysm]. / Trattamento chirurgico di una grande fistola coronarica tra arteria discendente anteriore e arteria polmonare, di grosso aneurisma sacculare e di coronaropatia severa trivasale.

A 60-year-old man with hypercholesterolemia and hypertension presented with acute coronary syndrome (SCA). The ECG showed lateral ischemia (T-wave inversion in V4-V6, D1 and aVL) and echocardiography showed normal left ventricular wall motion. Coronary angiography showed critical atherosclerotic lesions in the distal part of the left circumflex artery (LCx, culprit lesion), chronic total occlusion of the right coronary artery (RCA), significant but not critical stenosis in the middle part of left anterior descending artery (LAD), and a coronary artery to pulmonary artery (PA) fistula originating from the proximal part of the LAD and emptying into the PA via a coronary saccular aneurysm (12 x 12 x 10 mm). A multidetector row computed tomography angiography (CTA) confirmed the coronary artery fistula, which was treated with surgical approach. The patient underwent aneurysmorrhaphy with CAF closure and coronary artery bypass grafting on the RCA and LCx. The postoperative course was uneventful and the patient was discharged on postoperative day 14. CTA was useful for understanding the spatial relation of the CAF and the connection with the PA.

Sinoatrial nodal artery fistula to bronchial arteries originating from the right coronary artery in the setting of chronic bronchiectasis and coronary artery disease.

We present a 67-year-old male with past medical history of hyperlipidemia, hypertension, and emphysema, and who was a former smoker, with dyspnea on exertion and chest pain.

[Pulmonary Artery Transection in Surgery for Coronary Artery Fistula].

Coronary artery fistula is a rare abnormality in the communication between a coronary artery and any of the cardiac chambers or major vessels. At present, there is no standard surgical treatment and the most appropriate method is selected on a case-by-case basis. We report one case of coronary artery fistulae in which pulmonary artery transection was required around the left main trunk (LMT). A 62-year-old man who had coronary artery fistulae with an aneurysm which increased from 12 mm to 16 mm in a two-year span. The fistula was located adjacent to the LMT. A complete aneurysm excision under cardiopulmonary bypass was performed, which required pulmonary artery transection. No postoperative complications occurred. Postoperative coronary computed tomography scan showed intact coronary arteries and complete aneurysm removal.

A Spitting-Cobra-Like Coronary-Pulmonary Artery Fistula in a Patient With Angina.

A 78-year-old woman with a history of hypertension, hyperlipidemia, and asthma was referred to her cardiologist for chest pain and dyspnea on exertion. After performing stress echocardiography, it was determined that closure of the fistula with coils was indicated. This case highlights that coronary fistula could be an unusual entity of angina, clinically improving after the occlusion procedure.

Thymoma with a feeding vessel from coincident coronary-pulmonary artery fistulas.

We report a rare case of a 68-year-old man with thymoma and coronary-pulmonary artery fistulas. The thymoma was 66 × 51 × 88 mm in size and accompanied by a feeding vessel originating from the coronary-pulmonary artery fistulas. We performed total thymectomy and resection of coronary-pulmonary artery fistulas at the same time, which has not been reported in the literature. The fistulas along with the left main trunk were successfully resected while temporarily transecting the main pulmonary artery. This strategy was a useful option for obtaining a good field of vision around the left main trunk behind the main pulmonary artery.

Severe obstructive sleep apnoea, aortic dissection and aortopulmonary fistula in a 56-year-old patient with syncope.

We present a case of a 56-year-old patient with obstructive sleep apnoea (OSA) presenting with acute decompensated heart failure and signs of cardiogenic shock. Echocardiography and CT imaging led to the diagnosis of acute type A aortic dissection (AD) complicated by aortopulmonary fistula (APF). The patient underwent successful surgical repair with complicated postoperative course including pulseless electrical activity arrest. This case highlights the underappreciated role of untreated OSA as a risk factor for AD. Furthermore, it presents an opportunity to review APFs as a rare complication of AD. We discuss the available evidence linking OSA and AD, review currently reported cases of APF, briefly outline the haemodynamics of this acute left-to-right shunt and discuss management of this rare but deadly complication.

Percutaneous Hydrogel Coil Embolization of Aneurysms and Coronary Artery Fistulae in Congenital Heart Disease.

Patients with congenital heart disease frequently have aneurysms or coronary artery fistulae that necessitate treatment. Metal vascular coils have been a mainstay of treatment for these lesions. In 2002, coils coated or filled with expandable hydrogel were introduced to treat cerebral aneurysms; however, the literature on their use in patients with congenital heart disease is limited. We present 5 cases in which large vascular lesions in children or adolescents with congenital heart disease were successfully occluded with hydrogel coils.

Rare case of congenital coronary artery fistula coexistent and coalesced with aortopulmonary fistula.

Coronary artery fistula (CAF) is an uncommon congenital heart disease. Furthermore, aortopulmonary fistula is a rare congenital heart disease of adult onset. We report the case of a 79-year-old man who presented with chest pain. ECG-gated cardiac CT and coronary artery angiography revealed an anomalous vessel arising from the right coronary cusp and a CAF from the left coronary descending artery. These fistulas coalesced and drained into the same portion of the pulmonary artery. Haemodynamic studies revealed that the estimated systemic-to-pulmonary flow ratio was 1.18. The mean pulmonary pressure was 14 mm Hg. We decided against surgical intervention due to his advanced age and lack of heart failure symptoms. The patient did not have any worsening heart failure and chest pain on follow-up. This was a rare case of CAF coexistent and coalesced with an aortopulmonary fistula.

Congenital coronary artery-to-pulmonary fistula with giant aneurysmal dilatation and thrombus formation: a case report and review of literature.

BACKGROUND: Coronary artery-to-pulmonary artery fistula is a rare disorder characterized by abnormal vascular communication between the coronary artery and pulmonary artery. While most patients remain asymptomatic, some might exhibit symptoms of myocardial ischemia, congestive heart failure, or even sudden cardiac death if coronary aneurysm, thrombosis, infective carditis, or other congenital cardiac defects coexist. Case presentation We present a 66-year-old male complaining of angina pectoris with a history of hypertension and active smoking. He was diagnosed with a coronary aneurysm based on coronary computed tomography angiography. We subsequently identified a coronary artery-to-pulmonary artery fistula with giant aneurysmal dilation on coronary angiography. Ultimately we conducted surgery ligation and aneurysmorrhaphy. During surgery, we discovered newly formed thrombus within the aneurysmal cavity. Histological analysis of the aneurysmal wall supported the diagnosis of the congenital disorder. Our patient was successfully discharged and remained asymptomatic at two months of follow-up. CONCLUSION: We presented a rare and complex combination of congenital coronary artery-to pulmonary artery fistula, giant coronary aneurysmal dilatation, and thrombosis through multi-modality evaluations.

[Surgical Repair of Giant Coronary Artery Aneurysm Associated with Coronary-pulmonary Artery Fistulae;Report of a Case].

A 61-year-old woman was referred to our hospital with a complaint of chest compression. Coronary angiography revealed a giant coronary artery aneurysm, located in the middle of a coronary-pulmonary artery fistula originating from the right coronary artery. Another fistula was also shown between the left anterior descending artery and the pulmonary artery. Surgical correction was indicated due to the risks of the aneurysmal rupture and coronary events. Under cardiopulmonary bypass, suture-closure of the coronary artery aneurysm and ligations of the fistulae were carried. Postoperative coronary angiography showed no aneurysm or fistula, and she was discharged uneventfully on the 12th postoperative day.

Ruptured aneurysm of coronary arteriovenous fistula without aneurysmal coronary artery.

BACKGROUND: Approximately 25% of coronary arteriovenous fistulas present aneurysmal dilatation; however, spontaneous rupture of the aneurysm is rare. Most coronary arteries branching the feeding arteries demonstrate aneurysmal formation, possibly because of shunt flow. CASE REPORT: A 48-year-old woman was referred to our institution for surgical management of ruptured aneurysm of coronary arteriovenous fistula. The aneurysm was located on the left-anterior aspect of the pulmonary artery trunk, communicating with both left and right coronary arteries through two small feeding arteries draining into the pulmonary artery trunk. Both left and right coronary arteries showed normal diameter. The feeding arteries were ligated externally, and fistulous openings were closed within the aneurysm. Postoperative course was uneventful. CONCLUSION: Aneurysm of coronary arteriovenous fistula can occur in patients without aneurysmal coronary artery. Although the association of ruptured aneurysm with coronary fistulas is relatively rare, it should be considered a potential cause of acute cardiac tamponade.

Surgical Repair of Congenital Coronary Artery Fistula With Giant Aneurysm.

A 67-year-old man with a 3-year history of dyspnea on exertion arrived to our institution with discontinuous palpitations and short breath. He was diagnosed with congenital coronary artery fistula (CAF). Angiography revealed 3 giant aneurysmal formations and coronary artery calcification. We report a case of successful repair of CAF with a giant coronary aneurysm by closing the orifice and resecting the aneurysm and reconstructing the left coronary artery. The surgical procedure included closure from within a vessel dilated by aneurysm and excision of the aneurysm. We were able to completely obliterate the fistula and preserve the normal blood flow through the coronary arteries post operation. The postoperative course was eventful, but the patient was discharged home. The patient was doing well at his 28-month follow-up visit.

Electrocardiographic findings of Wellens syndrome due to coronary artery-pulmonary artery fistula.

A coronary artery fistula (CAF) is an abnormal connection between a coronary artery and any of the four cardiac chambers, the large vessels, or other vascular structures. Wellens syndrome is an ST-segment elevation myocardial infarction equivalent. Although both Wellens syndrome and CAFs have been reported in the literature, they have rarely been reported in the same patient. We herein report a case clinically diagnosed as Wellens syndrome by electrocardiography (ECG) findings; coronary angiography subsequently showed a fistula originating from the left anterior descending artery and draining into the pulmonary artery. The ECG findings then returned to normal after the fistula had been closed by controlled-release coils. These events confirmed that the abnormal ECG findings of Wellens syndrome were due to the CAF.

[Coronary-pulmonary Artery Fistula Manifested by Cardiac Tamponade;Report of a Case].

Coronary-pulmonary artery fistula( CPAF) is a relatively rare congenital malformation. We successfully treated a patient who presented with cardiac tamponade due to ruptured CPAF. A 58-year-old woman was admitted to our hospital due to consciousness disorder. Enhanced computed tomography revealed hemopericardium, and she was diagnosed with cardiac tamponade due to a ruptured coronary artery aneurysm with fistula arising from the right coronary and entering the main pulmonary artery. Therefore, emergency operation was performed. Under cardiopulmonary bypass, the aneurysm was opened and the ostium of the fistula was closed with pledgetted mattress sutures. After ligating the tortuous CPAF, the aneurysmal wall was sutured. Postoperative course was uneventful, and she was discharged on postoperative day 16.

An unknown mass on the cardiac surface with huge coronary aneurysm and fistula: A case report.

Cardiac mass is rare in the clinic and can be primary or secondary. It is quite rare to find a mass only on the cardiac surface. Today we report a patient with a cardiac mass grown on the cardiac surface and also had a coronary aneurysm combined a coronary fistula, pathology examination showed that the mass was not a tumor but an aneurysm with thrombosis. This is the first time that a primary thrombus discovered on the surface of the heart.
