Abstract:
Reperfusion injury is thought to occur during coronary recanalisation but rarely produces clinically significant effects other than arrhythmia. We report an unusual case of Ventricular Septal Defect (VSD) developing after successful disobliteration of the right coronary artery. In this case clinical, electrocardiographic and biochemical evidence of myocardial injury developed 6 hours after successful percutaneous recanalization of the infarct related artery. A rapidly developing VSD soon became apparent necessitating surgical intervention to repair the defect. Unfortunately the patient died soon after surgery.

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

During diastole, all four heart chambers relax. The atrioventricular (AV) valves open, and the semilunar valves close. This phase sees the lowest chamber pressures, promoting ventricular filling. Venous blood enters the heart through the...
