Cardiac Surgery

Cardiothoracic surgery includes coronary artery bypass surgery (CABG), heart valve repair or replacement, left ventricular assist device (LVAD) placement, heart transplant, assisting in minimally invasive transcatheter valve structural heart procedures such as TAVR, left atrial appendage (LAA) occlusion, septal myectomy, surgical ablation for arrhythmias, and reconstruction of the heart in congenial heart disease cases.

How did the pig heart transplant patient die? A preventable infection may be to blame

The genetically modified pig heart appears to have been infected with a porcine virus, according to the surgeon who performed the initial transplant. 

Carotid endarterectomy (CEA) is not associated with a significant reduction in the risk of dementia, according to a new analysis published in the European Journal of Vascular & Endovascular Surgery.[1] However, the study’s authors noted, it did still lead to considerable improvements in stroke risk.

Carotid endarterectomy does not reduce long-term dementia risk

However, researchers noted, there was still a clear improvement in stroke risk.

COVID-19 vaccines improve outcomes for heart transplant patients

“In light of more infectious COVID-19 variants and ongoing high rates of transmission, COVID-19 vaccination for all orthotopic heart transplant recipients is of paramount importance,” the authors concluded.

Penn State researchers receive more than $3 million to develop new-look artificial heart

The group will be working to develop a wireless artificial heart that can last at least 10 years. 

VIDEO: TAVR durability outperforms surgical valves

Michael J. Reardon, MD, professor of cardiothoracic surgery and Allison Family Distinguished chair of cardiovascular research at Houston Methodist DeBakey Heart and Vascular Center, presented pooled data at ACC.22 from the CoreValve SURTAVI trials that found transcatheter aortic valve replacement (TAVR) was more durable than surgical aortic valve replacement (SAVR) devices.
