Oxygen Reserve Index and Arterial Partial Pressure of Oxygen: Relationship in Open Heart Surgery.

Background: Mild to moderate hyperoxia is potentially beneficial to patients undergoing open heart surgery. Oxygen Reserve Index (ORI) is a novel parameter that correlates to arterial oxygen tension (PaO) in the hyperoxic range. This prospective study aimed to assess whether the relationship between ORI and PaO remains intact in the setting of open-heart surgery.

Upper mini sternotomy approach for pulmonary artery banding: A single centre experience.

Background: Pulmonary artery banding (PAB) remains a crucial technique in modern cardiac surgery. Left lateral thoracotomy, median sternotomy, and left anterior thoracotomy are well-known approaches. With significant scarce reports addressing the application of the upper mini sternotomy approach for PAB, this study aims to share experience and report outcomes of patients operated upon using this approach and its impact on facilitating the redo surgery.

Three-dimensional transesophageal echocardiography incremental value in a rare case of a bileaflet tricuspid valve.

Detailed assessment of the tricuspid valve using two-dimensional echocardiography is always challenging, as only two of three leaflets can be seen at a time. Three-dimensional echocardiography can provide the enface view of the tricuspid valve that allows simultaneous visualization of all of the three leaflets. In a 42-year-old male patient scheduled for pulmonary endarterectomy, 3DTEE showed that the tricuspid valve is bileaflet, with one septal and another lateral leaflet.
