Abstract Background Aortocoronary arteriovenous fistula (ACAVF) due to iatrogenic bypass grafting to a cardiac vein is an exceedingly rare complication resulting from coronary artery bypass grafting (CABG) surgery. If not identified in a timely fashion, ACAVF has known significant clinical consequences related to left to right shunting and possible residual myocardial ischemia. Case presentation An 82-year-old male with a history of CABG, presented with dyspnea. Over the span of 2 years following CABG, the patient experienced progressive exertional dyspnea and peripheral edema. The patient was found to have a new cardiomyopathy with a severely reduced ejection fraction at 30–35%. The patient underwent diagnostic left heart catheterization, and an ACAVF was discovered between a saphenous vein graft and the coronary sinus. The patient underwent successful percutaneous coiling of the ACAVF with no residual flow. Follow-up echocardiography at 3 months revealed restoration of left ventricular systolic function to 50% and significant improvement in heart failure symptoms. Conclusions ACAVF is an exceedingly rare iatrogenic complication of CABG that may result in residual ischemia from the non-grafted myocardial territory and other sequelae relating to left to right shunting and a high-output state. Management for this pathology includes but is not limited to the use of percutaneous coiling, implantation of covered stents, graft removal and regrafting, and ligation.

Adrenergic Control

alpha-Adrenergic control of the oxygen delivery to the myocardium during exercise was investigated in eight conscious dogs instrumented for chronic measurements of coronary blood flow, left ventricular (LV) pressure, aortic blood pressure, and heart rate and sampling of arterial and coronary sinus blood. After alpha-adrenergic receptor blockade a standard exercise load elicited a significantly greater increase in heart rate, rate of change of LV pressure (LV dP/dt), LV dP/dt/P, and coronary blood flow than was elicited in the unblocked state. In contrast to the response pattern during control exercise, there was no significant change in coronary sinus oxygen tension (PO2), myocardial arteriovenous oxygen difference, and myocardial oxygen delivery-to-oxygen consumption ratio. It is concluded that the normal relationship between myocardial oxygen supply and oxygen demand is modified during exercise after alpha-adrenergic blockade, whereby oxygen delivery is better matched to oxygen consumption. These results indicate that the increase in coronary blood flow and oxygen delivery to the myocardium during normal exercise is limited by alpha-adrenergic vasoconstriction.

Osmotic Reflection Coefficient

Myocardial edema formation, which has been shown to compromise cardiac function, and increased epicardial transudation (pericardial effusion) have been shown to occur after elevation of myocardial venous and lymphatic outflow pressures. The purposes of this study were to estimate the hydraulic conductance and osmotic reflection coefficient for the epicardium and to determine the effect of coronary sinus hypertension and cardiac lymphatic obstruction on epicardial fluid flux (JV,e/Ae). A Plexiglas hemispheric capsule was attached to the left ventricular epicardial surface of anesthetized dogs. JV,e/Ae was determined over 30-min periods for three intracapsular pressures (-5, -15, and -25 mmHg) and two intracapsular solutions exerting colloid osmotic pressures of 7.0 and 2.0 mmHg. Hydraulic conductance was estimated to be 3.7 +/- 0.5 microliters.h-1.cm-2.mmHg-1. An osmotic reflection coefficient of 0.9 was calculated from the difference in JV,e/Ae of 16.5 +/- 8.4 microliters.h-1.cm-2 between the two solutions. Graded coronary sinus hypertension induced a linear increase in JV,e/Ae, which was significantly greater in dogs without cardiac lymphatic occlusion than in those with occlusion.

Left Ventricular Pacing

We report a case of a patient with an additional great cardiac vein, discovered during the implantation for car­diac resynchronization therapy (CRT). Anomalies of the coronary sinus and its tributaries may cause difficulties in appropriate implantation of the left ventricular lead but they can also be considered as alternatives for lead placement. Although unusual angiogram of the coronary venous system, a left ventricular pacing lead was successfully placed in the left marginal vein. To settle diagnostic doubts, multislice computed tomography was carried out.

Oxygen Balance

The effects of beta-adrenergic blockade upon myocardial blood flow and oxygen balance during exercise were evaluated in eight conscious dogs, instrumented for chronic measurements of coronary blood flow, left ventricular pressure, aortic blood pressure, heart rate, and sampling of arterial and coronary sinus venous blood. The administration of propranolol (1.5 mg/kg iv) produced a decrease in heart rate, peak left ventricular (LV) dP/dt, LV (dP/dt/P, and an increase in LV end-diastolic pressure during exercise. Mean coronary blood flow and myocardial oxygen consumption were lower after propranolol than at the same exercise intensity in control conditions. The oxygen delivery-to-oxygen consumption ratio and the coronary sinus oxygen content were also significantly lower. It is concluded that the relationship between myocardial oxygen supply and demand is modified during exercise after propranolol, so that a given level of myocardial oxygen consumption is achieved with a proportionally lower myocardial blood flow and a higher oxygen extraction.
