purpose: compaison of excyclotorsion induced by horizontal transposition of vertical rectus muscles versus vertical transposition of horizontal rectus muscles in rabbit eyes. methods: in this exprimental study, group 1 underwent full tendon nasal transposition of the superior rectus and full tendon temporal transposition of the inferior rectus (10 adult rabbits); group 2 underwent superior tran...

Cardiac surgery has been a vibrant field since the early pioneering procedures were attempted, became successful, and eventually reproducible. From the successful closure of a patent ductus arteriosus in 1938 and the Blalock-Taussig shunt, discovery and innovation have been the hallmarks of cardiac surgery. Dr John Gibbon’s first clinical use of the heart lung machine in 1953 opened the door to...

A sinus of Valsalva aneurysm (SOVA) is an uncommon cardiac anomaly occurring in less than 1% of patients undergoing open cardiac surgical procedures (1). Approximately 65-85% of SOVAs originate from the right sinus of Valsalva, while SOVAs originating from noncoronary (10-30%) and left sinuses (<5%) are less common (2). It may be congenital or acquired in origin and may rupture into any of the ...

The coronary sinus (CS) is an important vascular structure that allows for access into the coronary veins in multiple interventional cardiology procedures, including catheter ablation of arrhythmias, pacemaker implantation and retrograde cardioplegia. The success of these procedures is facilitated by the knowledge of the CS anatomy, in particular the recognition of its variants and anomalies. T...

Chylothorax due to goiter is an exceptional compressive complication; compressive goiter usually causes narrowing of the trachea and compression of the esophagus or jugular vein. Because of anatomical relationship, right-side chylothorax is caused by a very large and low-lying goiter. In those cases usually the surgical approach is a sternotomy instead of transcervical thyroidectomy, that is as...

About 19 000 cardiac surgical procedures are carried out annually in the United Kingdom, 4000 being for congenital defects (UK Cardiac Surgical Register: Society of Thoracic and Cardiovacular Surgeons of Great Britain and Ireland, 1983). Most of these procedures use the median sternotomy incision for access to the heart and great vessels. Epigastric incisional hernias may occur as a complicatio...

Background Nowadays, the use of cardiopulmonary bypass (CPB) followed by systemic hypothermia is common in cardiac surgery procedures. CPB causes a systemic inflammatory response syndrome (SIRS) that is markedly expressed in congenital caridiosurgical surgery programe resulting with deleterious consequences. Those effects are mediated through cytokines and others mediators of acute inflammatory...

Background: The development of neonatal cardiology and cardiac surgery, as well as the earlier diagnosis of congenital defects, arrhythmias, and cardiac conduction disorders, contributed to the systematic increase of the number of children and young adults undergoing electrophysiological procedures, as well as to the reduction of the age at which these procedures are performed. Children requiri...

Percutaneous branch pulmonary artery (PA) stenting can be challenging, especially in patients with stenosis of the right ventricular (RV) outflow tract or tortuous PA branches. In these cases, a hybrid procedure deploying PA stent(s) during cardiac surgery provides an alternative to relieve branch PA stenosis. The Mayo Clinic Congenital Cardiac surgical database was used to identify all patient...
