Patient discussion about AV

Q. I developed an AV Fistula after a heart catherization procedure. I am bleeding through the tissues in left arm I am on coumadin, but currently have a lower than usual INR. Corrective surgery was scheduled for yesterday, but had to be delayed. I am concerned that I have a large amount of blood (dark red) bleeding though the tissues right under the skin in my left arm. Should I seek immediate medical attention? The bleeding is over approximately a 3 and 1/2" area on my left arm. Came about in a period of a few minutes.

A. well, you are on blood thinners. i wouldn't take the chance. i mean- i'm not sure i follow what is happening over there. it could be a severe problem or nothing. i would let a doctor check it out. the worse thing that could happen is you wasting a day at the hospital, on the other end of that scenario- you can end up dead. i would go with the first one.

Repeat echocardiography at one month of age showed only modest changes--both twins had mild right atrial dilation, mild to moderate right ventricular dilation with moderate hypertrophy and good qualitative systolic function, normal left ventricular size, and systolic function, mild central and right atrioventricular valve regurgitation, and no evidence of a persistent PDA.
The length of right atrioventricular (AV) valve and left cusp of left atrioventricular valve (AV) were longer in chick embryos belonging to control group as compared to those in experimental group but this was not statistically significant.
Intracardiac defects comprised a single atrioventricular valve with a severely hypoplastic ventricle and severe subvalvar pulmonary stenosis (see Figure 3).

Many risk factors associated with poor clinical outcomes in Fontan operation have been identified in clinical studies [611], which typically include high pulmonary vascular resistance, low ventricular ejection fraction, increased ventricular diastolic stiffness, and atrioventricular valve regurgitation.
Two-thirds of patients with DCM, especially those over 55 years of age, have persistently low arterial pressure, ventricular arrhythmias and/or atrioventricular valve incompetence and die within 5 years of their first symptom.
At 12 weeks after presentation, results of an echocardiogram revealed persistent right atrioventricular valve regurgitation, moderate ascites, and dilation of hepatic veins.
