Perioperative implications of Coronary–cameral fistula

Coronary–cameral fistulas (CCFs) are mostly congenital in origin and rarely acquired. Clinical symptoms are decided by the hemodynamic significance of the coronary fistula. Even in asymptomatic patients, it is essential to know about coronary CCF particularly if the patient is to undergo cardiac surgery with cardioplegic cardiac arrest. Incidental finding of coronary CCF should never be ignored. Intraoperative myocardial protection and methods used are significantly influenced by such fistula.

Ipsilateral foot drop after aortobifemoral bypass

Peripheral nerves can be injured by a direct result of the anesthetic technique of regional anesthesia or it can be contributed/compounded by poor perioperative positioning and padding, tourniquets, and the nature of surgery and diseases affecting the microvasculature of nerves. We present a case of perioperative peripheral nerve injuries which could not be explained by anesthesia technique nor surgery per se.

A curious case of raised gradient across mitral bioprosthetic valve

High Doppler valve gradient is generally suggestive of valve thrombosis. However, it should be corroborated with the finding of restricted leaflet movement to confirm the diagnosis. In the present case, abnormally high gradient was not associated with limited leaflet movements or any valve thrombus.
