Transit-time flow measurement parameters after protamine infusion in CABG surgeries.

Objective: The objective of this study is to evaluate protamine sulfate effects on graft's blood flow by comparing transit-time flow measurement (TTFM) values before and after protamine administration.

Methods: This is an observational study with data collected between years 2018 and 2020. Immediate graft patency was evaluated using TTFM.

A benchmark in the isolated tricuspid valve surgery is necessary.

Advances in surgical techniques, enabling correction of regurgitation, and preserving the tricuspid valve, are also factors that encourage early surgical indication and improve long-term outcomes.

The use of internal mammary vein in coronary artery surgery.

Arterial revascularization, and in particular, left internal mammary artery (LIMA), has shown to improve survival of patients with coronary artery disease. Complete revascularization often requires the use of other grafts and saphenous vein graft is still the most common conduit used. Several other types of grafts have been utilized during revascularization, including the radial artery and gastroepiploic artery.

Geometric reconstruction of a left ventricular aneurysm with coronary artery bypass graft.

Left ventricular aneurysm is a late mechanical complication of untreated acute myocardial infarction. It has become relatively rare since the development of percutaneous cardiac intervention.  Most aneurysms are located at the anterior ventricular wall, and are caused by total occlusion of the left anterior descending artery.
