Conventional versus minimally invasive extra-corporeal circulation in patients undergoing cardiac surgery: A randomized controlled trial (COMICS).

Introduction: The trial hypothesized that minimally invasive extra-corporeal circulation (MiECC) reduces the risk of serious adverse events (SAEs) after cardiac surgery operations requiring extra-corporeal circulation without circulatory arrest.

Methods: This is a multicentre, international randomized controlled trial across fourteen cardiac surgery centres including patients aged ≥18 and <85 years undergoing elective or urgent isolated coronary artery bypass grafting (CABG), isolated aortic valve replacement (AVR) surgery, or CABG + AVR surgery. Participants were randomized to MiECC or conventional extra-corporeal circulation (CECC), stratified by centre and operation.

Fix and pull technique for retrieval of intracoronary unexpanded-stent entrapment.

During left main (LM) bifurcation PCI using T and small protrusion (TAP) technique, after deployment of LM-left anterior descending (LAD) stent, left circumflex (LCx) stent was entangled at LM ostium with balloon and wire slippage. Ping-pong (dual) guide catheters were used to simultaneously fix the LM-LAD stent and snare the trapped stent. This technique proved effective in retrieving the lost stent and minimizing LM stent deformation.

Diagnostic accuracy of multi-slice computed tomography in identifying lesion characteristics in coronary total occlusion.

We performed this study to compare the sensitivity and specificity of multi-slice computed tomography (MSCT) to coronary angiography (CA) in detecting coronary total occlusion (CTO) lesion characteristics. Moreover, we analyzed the association between these characteristics and the risk of revascularization failure. Fifty patients with confirmed CTO diagnosis were tried for revascularization using the antegrade (all 50) or retrograde (in failed nine antegrade interventions) approaches.

Estimation of kidneys and urinary bladder doses based on the region of interest in fluorine-fluorodeoxyglucose positron emission tomography/computed tomography examination: a preliminary study.

Background: Kidneys and urinary bladder are common physiologic uptake sites of 18fluorine-fluorodeoxyglucose (F-FDG) causing increased exposure of low energy ionizing radiation to these organs. Accurate measurement of organ dose is vital as F-FDG is directly exposed to the organs. Organ dose from F-FDG PET is calculated according to the injected F-FDG activity with the application of dose coefficients established by International Commission on Radiological Protection (ICRP).

Autologous Diced Cartilage in Nasal Septoplasty.

Diced rib cartilage is an acceptable option in severe nasal deformities. We present our preliminary experience in KAMC in nasal septoplasties using the autologous diced costal cartilage. This is a retrospective study of the 22 cases who needed the autologous diced costal cartilage in our centre in 4 years.
