Recurrent coronary stent thromboses and myocardial infarctions.

Although stent thrombosis is a recognized complication of coronary intervention, recurrent stent thrombosis is rarely reported. We present a patient who suffered 3 ST-segment elevation myocardial infarctions associated with repeated stent thromboses within a month and a half. Although a potentially mechanical cause of thrombosis was identified in the only baremetal stent implanted in this case, no predisposing factors were seen for the 2 drug-eluting stents (DES).

Single coronary artery with the absence of a left anterior descending artery.

Anomalous origin of coronary arteries is discovered incidentally during coronary arteriography or at autopsy, and awareness among angiographers is required. We describe a case with a rare combination of a single coronary artery originating from the right sinus of Valsalva associated with an absent left anterior descending artery and a secundum-type atrial septal defect.

Intraoperative transesophageal echocardiography with a special focus on a patient undergoing advanced robotic-assisted procedures.

Intraoperative echocardiography (IOE) has earned a major role in surgical decision-making and helps the cardiac surgeon decide and proceed with appropriate intervention based on the visualized pathology. With the advent of minimally invasive surgical techniques and robotic-assisted operations, more emphasis and dependence has been placed on IOE. We describe our experience with IOE during mitral valve repair at our center, which is one of the pioneer centers for these telemanipulation techniques.
