1/11. High-output heart failure resulting from a remote traumatic aorto-caval fistula: diagnosis by echocardiography.

    Congestive heart failure (CHF) due to high output states is known to occur in a variety of systemic illnesses and in patients with arterial-venous fistulas. This paper reports the case of a 45-year-old man admitted to the emergency room with a diagnosis of new onset atrial fibrillation and CHF, whose past medical history was not significant except for a gunshot wound to his abdomen 22 years previously. The etiology of his CHF together with the cardiomegaly and hyperdynamic left ventricular systolic function was unknown. A subcostal view routinely done during transthoracic echocardiography revealed a severely dilated inferior vena cava and the presence of an aorto-caval fistula by color doppler. The patient underwent successful corrective repair with dramatic improvement in symptoms and resolution of the atrial fibrillation, and cardiac size returned to normal. This rare case emphasizes that patients with refractory CHF must be closely examined with particular attention to palpation and auscultation over all scars, irrespective of the duration since any traumatic or surgical event.

2/11. liver transplantation for hepatic arteriovenous malformation with high-output cardiac failure in hereditary hemorrhagic telangiectasia: hemodynamic study.

    We describe a case of orthotopic liver transplantation used as a therapeutic method to correct high output cardiac failure related to a liver arteriovenous fistula due to hereditary hemorrhagic telangiectasia. Detailed hemodynamic changes as they occurred during liver transplantation are described.

3/11. Perioperative management of biventricular failure after closure of a long-standing massive arteriovenous fistula.

    PURPOSE: To report the perioperative management of arteriovenous fistula (AVF) closure in a patient with high-output heart failure and pulmonary hypertension. CLINICAL FEATURES: In a 71-yr-old man, closure of a long-standing massive AVF between the right femoral artery and vein was performed. After closure of the AVF, his pulmonary artery pressure (PAP) increased from 52/21 mmHg to 68/26 mmHg, his cardiac index decreased from 5.27 L.min(-1).m(-2) to 3.18 L.min(-1).m(-2), and his pulmonary wedge pressure increased from 15 mmHg to 32 mmHg due to an acute increase in afterload. Co-administration of prostaglandin E and a phosphodiesterase III inhibitor improved the cardiac index and the PAP. CONCLUSIONS: Surgical closure of the fistula may not always lead to resolution of the high output cardiac failure. In this case, afterload management using arterial dilators (prostaglandin E1, phosphodiesterase III inhibitor), use of inotropic drugs (phosphodiesterase III inhibitor), and close attention to volume status was crucial for a successful outcome after surgical AVF closure.

4/11. High output cardiac failure caused by multiple giant cutaneous hemangiomas.

    A 59-year-old Chinese woman had multiple giant cutaneous cavernous hemangiomas on her right upper limb which resulted in high output heart failure because they presented as a large peripheral arteriovenous (A-V) fistula. Selective right subclavian arteriography showed extremely hypertrophic arteries of the patient's right arm with a tremendous blood supply to the soft tissues; neither superselective embolization nor surgery seemed applicable to this patient. The patient's heart failure was not satisfactorily controlled by conservative treatment.

5/11. High output heart failure 8 months after an acquired arteriovenous fistula.

    Congestive heart failure (CHF) due to hyperkinetic states can occur in systemic diseases and in arteriovenous fistulas. An 18 year old Turkish male patient complaining of dyspnea and palpitations, who had suffered a stab wound to his abdomen eight months earlier, was admitted to our clinic. auscultation revealed a systolodiastolic murmur over the entire abdomen. Chest x-rays demonstrated significant cardiomegaly. echocardiography revealed biatrial enlargement and significant mitral and tricuspid regurgitation accompanied by dilatation of the inferior vena cava. Right heart catheterization showed increased oxygen saturation at the inferior vena cava. A diagnosis of an aortocaval fistula was made by aortography. The symptoms subsided and valvular regurgitations ceased alter surgical correction. This rare case demonstrates the significance of routine physical examination and history of the patient.

6/11. Successful intervention for high-output cardiac failure caused by massive renal arteriovenous fistula-a case report.

    Renal arteriovenous fistula is a rare clinical entity that may produce high-output cardiac failure. This report describes the case of an 81-year-old woman in whom recurrent episodes of congestive heart failure developed over a relatively short time. A massive renal arteriovenous fistula was visualized by CT scan and arteriography. Successful embolization was performed under hemodynamic monitoring with complete resolution of the patient's symptoms.

7/11. arteriovenous fistula-associated high-output cardiac failure: a review of mechanisms.

    High-output cardiac failure can be a rare complication of high-output arteriovenous fistula. The authors present a case in which a hemodialysis patient with a high-flow arteriovenous fistula has cardiac failure that improves with fistula closure. The hemodynamic effects of a fistula are reviewed, and the hemodialysis literature regarding high-output cardiac failure is summarized. To gain insight into the problem of high-output cardiac failure, research efforts should focus on the prospective monitoring of high-access flows.

8/11. Remission of high-output heart failure after surgical repair of 30-month arteriovenous femoral fistula: case report.

    We present a 15-year-old male patient who was admitted to our hospital because of breathlessness and palpitations at minimal physical effort (new york Heart association class II). The patient had a history of an abdominal and left thigh firearm wound that was surgically treated 30 months earlier. auscultation over the left femoral groin region revealed a systolodiastolic murmur. X-ray examination of the chest demonstrated significant cardiomegaly. Transthoracic echocardiography revealed an enlargement of 4 cardiac chambers, as well as significant mitral and tricuspid regurgitation. Vascular ultrasound of the femoral artery and vein confirmed the diagnosis of a traumatic arteriovenous fistula. The patient underwent surgical correction of the fistula, after which the symptoms subsided rapidly. Follow-up echocardiography performed 2 months after surgical repair showed a substantial reduction of cardiac size and a nearly complete absence of valvular regurgitations. This case highlights the importance of the recognition of arteriovenous fistulas as a cause of unexpected heart failure and demonstrates that the condition may improve substantially and rapidly after fistula correction.

9/11. High-output heart failure caused by arteriovenous fistula long after nephrectomy.

    A 70-year-old Japanese woman was admitted to our hospital because of anasarca. At 32 years of age, she had undergone nephrectomy for renal tuberculosis. A continuous abdominal bruit was heard. The chest X-ray showed cardiomegaly and dilatation of the pulmonary artery. Abdominal three-dimensional computed tomography scanning clearly revealed an arteriovenous fistula. cardiac catheterization disclosed cardiac output of 9.2 l/min and a step-up of oxygen saturation at the renal vein level of the inferior vena cava. Surgical closure of the fistula promptly decreased her cardiac output and improved the heart failure. This is a rare case of an arteriovenous fistula developing long after nephrectomy and causing high-output heart failure.

10/11. Multiple coronary artery fistulae communicating through a sinusoid and emptying into the left ventricle.

    This case report describes the occurrence of multiple coronary artery fistulae emptying into the left ventricle and includes a small communication into the left atrium. The initial diagnosis of a coronary artery fistula was made by standard and nonstandard transthoracic two-dimensional echocardiogram and Doppler interrogation. Later, multiple coronary fistulae communicating through a sinusoid and draining into the left-sided chambers were confirmed by angiography.
