Forging a sustainable sky: Unveiling the pillars of aviation e-fuel production for carbon emission circularity.

In 2021, airplanes consumed nearly 250 million tons of fuel, equivalent to almost 10.75 exajoules. Anticipated growth in air travel suggests increasing fuel consumption.

A prospective, single-center, randomized study to assess whether automated coregistration of optical coherence tomography with angiography can reduce geographic miss.

Objective: We sought to evaluate whether automated coregistration of optical coherence tomography (OCT) with angiography reduces geographic miss (GM) during coronary stenting.

Background: Previous intravascular ultrasound or OCT studies have showed that residual disease at the stent edge or stent edge dissection was associated with stent thrombosis or edge restenosis. This has been termed GM.

Defining the learning curve for robotic-assisted endoscopic harvesting of the left internal mammary artery.

Objective: Robotic-assisted techniques are continuing to cement their role in coronary surgery, particularly in facilitating the endoscopic harvesting of the left internal mammary artery (LIMA), regardless of how the subsequent bypass grafting is performed. As more surgeons attempt to become trained in robotic-assisted procedures, we sought to better define the learning curve associated with robotic-assisted endoscopic LIMA harvest.

Methods: Between January 2011 and July 2012, a total of 77 patients underwent robotic-assisted minimally invasive direct coronary artery bypass surgery at our institution.

Does dual antiplatelet therapy affect blood loss and transfusion requirements in robotic-assisted coronary artery surgery?

Objective: Patients who present for coronary surgery often receive preoperative dual antiplatelet therapy with aspirin and a thienopyridine derivative (clopidogrel or prasugrel), especially after a recent acute coronary syndrome. Studies have shown that patients on aspirin and clopidogrel are at increased risk for perioperative bleeding and related events. We sought to examine the impact of dual antiplatelet therapy on bleeding and transfusion requirements in patients undergoing robotic-assisted minimally invasive coronary artery bypass grafting.

Does body mass index affect outcomes in robotic-assisted coronary artery bypass procedures?

Objective: Obese patients pose unique technical challenges for minimal-access cardiac surgery. We sought to examine the effect of body mass index on short-term outcomes in robotic-assisted coronary surgery.

Methods: From January 2010 to November 2011, a total of 110 consecutive patients underwent robotic-assisted coronary surgery at our institution.

Long-Term Survival After Minimal Invasive Direct Coronary Artery Bypass (MIDCAB) Surgery in Patients With Low Ejection Fraction.

Objective: : The long-term survival after minimal invasive direct coronary artery bypass (MIDCAB) surgery to any coronary territory in patients with ejection fraction of ≤30% was investigated for the first time in literature.

Methods: : Seventy-three patients with primary MIDCAB and 89 patients with reoperative MIDCAB were studied including preoperative risk factors, operative details, early postoperative complications, and survival up to 10 years postoperatively.

Results: : Despite the high-risk profile of the patients, the MIDCAB approach for targeted revascularization resulted in excellent short-term results.

Off-pump Coronary Bypass Surgery in Patients With Low Ejection Fraction: Is There a Long-Term Survival Advantage?

Objective: : Long-term survival after off-pump surgery in patients with low ejection fraction was investigated.

Methods: : Three hundred forty-six patients with ejection fraction 30% or less with isolated off-pump coronary artery bypass surgery (OPCAB) were compared with a propensity matched historical group operated on-pump (ONCAB) and with data from literature after percutaneous coronary intervention and OPCAB surgery.

Results: : The lower invasiveness of OPCAB contributed to a significantly better 30-day survival, shorter postoperative length of stay, and fewer in-hospital complications.

Minimally invasive direct coronary artery bypass as a primary strategy for reoperative myocardial revascularization.

Objective: : Conventional reoperative coronary artery bypass grafting is associated with risk of sternal re-entry, injury to patent grafts, and embolization from diseased grafts. Sternal sparing minimally invasive direct coronary artery bypass (MIDCAB) avoids such risks in cases where it is technically feasible. We sought to examine in-hospital outcomes of reoperative MIDCAB surgery.

Less invasive intracardiac surgery performed without aortic clamping.

Background: Aortic clamping and cardioplegia delivery add complexity to performing intracardiac procedures through a right minithoracotomy. Recent publications have shown excellent patient outcomes after mitral valve (MV) procedures undertaken through thoracotomy on the fibrillating heart. We reviewed our experience with this approach.
