Anomolous coronary artery

Risk factors for infective endocarditis (IE) include congenital heart defects, poor dentition, immunosuppression, or recent instrumentation. The occupational hazard of a dog bite, combined with bicuspid aortic valve (BAV) led to IE. 16S ribosomal DNA was able to pinpoint the causative organism. A healthy 33-year-old postman presented in profound heart failure and sepsis due to aortic regurgitation and an aortic root abscess. He underwent emergency aortic valve replacement and was found to have a BAV and anomalous right coronary artery...

Therapeutic hypothermia is an accepted modality for improving neurologic outcome in patients who have sustained cardiac arrest with return of spontaneous circulation. Despite postresuscitative neuroprotection, it is uncommon to have patients who have undergone prolonged cardiopulmonary resuscitation to recover full neurologic function. An unusual case of sudden cardiac arrest in a young athlete with an anomolous right coronary artery is presented.

Two infants with anomolous origin of the left circumflex coronary artery from the pulmonary artery had to be operated on at ages 40 days and 30 days because of severe myocardial dysfunction. This illustrates that the clinical course of anomalous origin of the circumflex artery from the pulmonary artery may not always be as favorable as reported in the literature.

Optimal revascularization of the rare variant anomolous intracavitary left anterior descending coronary artery requires, by definition, entrance into the right ventricular cavity. We present a simple method to repair the ventriculotomy without risk of obliterating the left anterior descending coronary artery, septal perforators, or diagonal branches.

A case is presented of a 36-year old female who presented with signs of mitral regurgitation due to infective endocarditis. Investigation revealed an anomolous left coronary artery arising from pulmonary artery. She successfully underwent mitral valve replacement. Survival following mitral valve replacement and presentation with endocarditis have never been reported in this rare condition.
