Spasm of healthy native coronary arteries is rare but a serious cause of perioperative ischaemia after coronary bypass surgery. The authors report five characteristic cases. In each case, the spasm presented with giant ST elevation and haemodynamic changes. In one case, further coronary bypass surgery was required. In three cases, symptomatic treatment of the hypotension associated with diltiazem completely cured the problem. One case was complicated by a small myocardial infarction. There were no fatalities. Previously reported cases often describe very heavy therapeutic protocols, justified by the high risks of this condition. Due to the fact that it is not possible to identify a target-population, simple prophylactic treatment with diltiazem seems to be justified in patients undergoing coronary artery bypass surgery.

This study evaluated the extent to which obturation materials bypass fractured endodontic instruments positioned in the middle and apical thirds of severely curved simulated root canals using different obturation techniques. Sixty resin blocks with simulated root canals were used, each with a 50° curvature, a 6.5 mm radius of curvature, and a length of 16.

Its simplicity and robust weight loss outcomes have contributed to its increasing popularity. While traditionally performed as an inpatient procedure, recent trends towards ambulatory surgery have prompted interest in outpatient SADI.

The unique structure and location of the internal thoracic artery make it an ideal conduit for coronary artery bypass grafting surgery and autologous breast reconstruction. Variants with different characteristics have the potential to impact surgical success. This report presents a female body donor with a novel bilateral variation of the internal thoracic artery.

Objective: Cardiopulmonary bypass (CPB) via the right axillary artery (RAA) has become an alternative perfusion strategy, especially in complex aortic procedures. This study delineates our technique and outcome with direct axillary cannulation utilizing the Seldinger technique, which we adopted as the standard perfusion strategy in the sternum-sparing minimally invasive total coronary revascularization via left anterior thoracotomy (TCRAT) using CPB.
Methods: From November 2019 to December 2023, a total of 413 consecutive patients underwent nonemergent isolated coronary artery bypass grafting (CABG) via left anterior minithoracotomy on CPB with peripheral cannulation via the RAA and cardioplegic cardiac arrest, using this technique as a default strategy in the daily routine.
