Congestive Heart Failure Caused by Aortocaval Fistula after Nephrectomy.

Aortocaval Fistula in Rat: A Unique Model of Volume-Overload Congestive Heart Failure and Cardiac Hypertrophy

Despite continuous progress in our understanding of the pathogenesis of congestive heart failure (CHF) and its management, mortality remains high. Therefore, development of reliable experimental models of CHF and cardiac hypertrophy is essential to better understand disease progression and allow new therapy development. The aortocaval fistula (ACF) model, first described in dogs almost a centur...

High-output heart failure resulting from chronic aortocaval fistula.

A 61-year-old man was admitted to the hospital complaining of bilateral leg edema and dyspnea lasting for 1 month and resistant to diuretic therapy.

A case of congestive heart failure caused by secondary hypocortisolism

Congestive heart failure caused by secondary hypocortisolism is rare but clinically significant, because its appropriate treatment is effective. Severe hyponatremia with indefinite complaint resembling depression or persisting fever despite antibiotics may be important for establishing this diagnosis.

Aortocaval Fistula

A 77-year-old Caucasian male with a history of hypertension presented with sudden onset of lower back pain, nausea, and vomiting.
