UNLABELLED Left ventricular hypertrophy following volume overload is regarded as an example of cardiac remodeling without increased fibrosis accumulation. However, infarction is associated with increased fibrosis within the noninfarcted, hypertrophied myocardium, particularly in the subendocardial regions. It is conceivable to suppose that, as also occurs postinfarction, low coronary driving pr...

Aortocaval fistulas are most commonly the result of spontaneous rupture or erosion of an abdominal aortic aneurysm into the inferior vena cava (80-90%). The remaining 10-20% of aortocaval fistulas are usually the result of penetrating or iatrogenic trauma from gunshot or stab wounds. We report the case of a 19-year-old male, status post multiple gunshot wounds. To our knowledge, this is the fir...

Spontaneous aortocaval fistula is a rare complication of abdominal aortic aneurysms. We describe two cases of spontaneous aortocaval fistula. The first patient is a woman who was admitted with abdominal pain and pulsatile abdominal mass. Another patient was a man admitted with progressive abdominal pain and hypotension. Computed tomography (CT) scan in both patients showed an infrarenal aortic ...

A 67-year-old man was admitted with severe back pain and bilateral lower limb swelling. Enhanced computed tomography showed an infrarenal abdominal aortic aneurysm (92 × 75 mm(2)) and a short aortocaval fistula (7 mm). Immediately afterward, circulatory collapse occurred, and the patient was rushed to the operating theater. A much larger aortocaval fistula (22 × 35 mm(2)) than that demonstrated...

Background Besides cardiac load, the renin-angiotensin system (RAS) and aldosterone may regulate collagen accumulation during maturation or hypertrophic growth. The effect of cardiac volume overload on both left ventricular (LV) and right ventricular (RV) collagen and elastin and the possible role of the RAS in such changes have not yet been assessed. Methods and Results In the present study we...

INTRODUCTION We report a case of aortocaval fistula successfully treated by hybrid operation. CASE DESCRIPTION A 73-year-old female suffering from malignant lymphoma and painful leg edema was transferred to our institution. Computed tomography revealed an aortoiliac aneurysm. The inferior vena cava was compressed by displacement of the abdominal aortic aneurysm. The bilateral internal iliac a...

A 77-year-old Caucasian male with a history of hypertension presented with sudden onset of lower back pain, nausea, and vomiting. Initial vital signs included a pulse rate of 104 beats/minute, a blood pressure of 117/72 mm Hg, and pulse oximetry of 95% on room air. Abdominal examination revealed a midline pulsatile mass and bruit. The patient had bilateral lower extremity edema, which was worse...
