Novel adaptive mechanisms in hibernating animals may provide clues to mitigate cardiac injury

Novel adaptations discovered in hibernating animals may reveal ways to mitigate injuries associated with strokes, heart attacks and organ transplants, according to researchers at the University of Alaska Fairbanks and Duke University.

Cardiac surgery patients who received omega-3 supplementation experience reduced hospital stays

A new meta-analysis published in Clinical Nutrition found that cardiac surgery patients who received omega-3 polyunsaturated fatty acids (compared to placebo) in advance of surgery experienced reduced postoperative cardiac arrhythmias and significantly reduced the length of hospital stay by up to 2.4 days. The results are based on 11 RCT's with 1038 patients.

Study evaluates effectiveness of robotic approach over manual ablation in treating heart arrhythmia

Whether ablation of the highest-risk heart arrhythmia is best handled by a robot or the hands of an electrophysiologist should be answered by an international comparison of the two.

Common genetic variant in HO-1 gene linked to AKI risk following cardiac surgery

Testing for a common genetic variant may help reveal which patients face an increased risk of developing kidney damage following heart surgery. The findings, which come from a study appearing in an upcoming issue of the Journal of the American Society of Nephrology, may help investigators develop therapeutic strategies to mitigate this damage.

Japanese surgeons develop new technique to relieve airway obstruction in children

Several pediatric medical conditions, such as congenital heart disease, vascular compression, and congenital softening of the cartilage lining the trachea or bronchi, can compromise the airway and cause breathing difficulty.

RDAVR system improves survival of patients with severe aortic stenosis

When replacing a defective aortic valve with a new one, restoring function is the first priority. However, variables such as durability, length of surgery, duration of heart stoppage, size of the surgical incision, postoperative pain, and complications are other important considerations.

Study shows women undergoing TAVR have longer-term survival rate compared to men

Data from one of the largest national registries of transcatheter aortic valve replacement (TAVR) patients shows that although women are more likely to experience vascular complications in the hospital, their one-year survival rate is more favorable than men.

Study finds no gender-based differences on use of anticoagulation medications in TAVR patients

A study on the impact of using different anticoagulation medications on men and women who have undergone a transcatheter aortic valve replacement (TAVR) found no difference in early vascular complications or mortality.

Study shows short-term statin treatment does not benefit heart surgery patients

Giving daily doses of statins for a few days before and after heart surgery does not prevent heart muscle damage or the development of atrial fibrillation (AF), according to an international clinical trial led by the University of Oxford and funded by the British Heart Foundation.

Older adults experience greater survival rates after lung cancer surgery

Patients aged 65 years and older are living longer after lung cancer surgery, and with older people representing a rapidly growing proportion of patients diagnosed with lung cancer, this improved survival is especially significant, according to an article posted online today by The Annals of Thoracic Surgery.

Review focuses on autologous cell therapy that can be applied to cardiac surgery

The combination of cell and gene therapy is rapidly raising clinical interest, although their combination has been under investigation for several decades. This is mainly due to the availability and feasibility of clinically relevant gene delivery options. This review focuses on cell therapies for heart failure and their use combined with cardiac surgery as well as with gene therapy.

Two common approaches to post-operative AF equally safe, effective

Cleveland Clinic researchers, as part of the Cardiothoracic Surgical Trials Network, have found that two common approaches to post-operative atrial fibrillation - rhythm control and rate control - are equally safe and effective.

Patients undergoing mini-MVR have similar outcomes compared with conventional surgery

Patients undergoing minimally invasive mitral valve repair or replacement (mini-MVR) have similar outcomes as patients undergoing conventional surgery and also experience shorter hospital stays and fewer blood transfusions, according to an article posted online today by The Annals of Thoracic Surgery.
