February 12, 2018 Canadian Journal of Cardiology recently published a report by Dr. Chu and colleagues examining the increased adoption of FET techniques over traditional methods for treating complex aortic arch disease.
September 21, 2017 Aneurysms of the distal aortic arch and proximal descending thoracic aorta remain challenging to treat. Whereas thoracic endovascular aortic repair (TEVAR) with arch debranching has provided a more minimally invasive option for patients with such aneurysms, recurrent type Ia endoleaks can be difficult or impossible to treat with further endovascular intervention. We report the successful use of a hybrid arch and frozen elephant trunk graft for the treatment of a patient with a recurrent type Ia endoleak after TEVAR and arch debranching.
May 01, 2017 Drs. Michael Chu, Bob Kiaii, and colleagues in the Department of Surgery, Cardiac Division, investigate robotic-assisted direct coronary artery bypass (RADCAB) transfusion rate to determine whether performing the minimal invasive coronary surgery with percutaneous coronary intervention in one stage would increase the incidence of blood transfusion, morbidity, and length of stay.
October 20, 2016 We report the initial North American transcatheter aortic valve implantation (TAVI) experience with the Engager device. Transapical TAVI was performed in 4 patients (mean age 80 +/- 6 years, Society of Thoracic Surgeons score 5 +/- 1%). The valve was anatomically oriented and successfully implanted in all patients.
September 10, 2016 Conventional epicardial excision is believed to be the most effective method of surgically obliterating the left atrial appendage (LAA), although incomplete resection and residual LAA volume may undermine its effectiveness. We sought to compare the impact of conventional epicardial excision with a novel LAA pericardial patch exclusion on residual LAA volume (2016 Aug 26. [Epub ahead of print] PMID: 27571564 )
May 31, 2016 In 2014, the Canadian Cardiovascular Society (CCS) published a position statement on the management of thoracic aortic disease addressing size thresholds for surgery, imaging modalities, medical therapy, and genetics. It did not address issues related to surgical intervention. This joint Position Statement on behalf of the CCS, Canadian Society of Cardiac Surgeons, and the Canadian Society for Vascular Surgery provides recommendations about thoracic aortic disease interventions, including: aortic valve repair, perfusion strategies for arch repair, extended arch hybrid reconstruction for acute type A dissection, endovascular management of arch and descending aortic aneurysms, and type B dissection

October 13, 2015 Drs. Hegazy and Granton and colleagues, publish study that aims to develop a focused TEE examination tailored for the Emergency Dept and to evaluate TEE skill acquisition and retention by TEE-naïve Emergency Physicians following a focused 4-h curriculum.
September 24, 2015 The heart team at LHSC is the first in North America to implant Medtronic’s Engager Valve in a transcatheter aortic valve implantation (TAVI) procedure. The procedure was performed in February, less than one year after the team was the first in North America to implant another second generation TAVI device.
April 03, 2018 Cardiac surgeons and anesthetists team up for large study (over 200 patients were enrolled from March 2004 to November 2015), to assess graft and stent patency at 6 months, rate of bleeding, intensive care unit and hospital stay, rate of reintervention, and long-term clinical follow-up.
April 03, 2018 Transcatheter aortic valve implantation (TAVI) is the treatment of choice for inoperable and high-risk patients with severe aortic stenosis. Our objectives were to elucidate potential differences in clinical outcomes and safety between balloon-expandable versus self-expandable transcatheter heart valves (THV).
April 03, 2018 Coronary obstruction remains a challenging complication of transcatheter aortic valve replacement; however, a new self-expanding transapical prosthesis may reduce this risk. The purpose of this study was to evaluate the early 1-year outcomes of patients with low coronary heights who received the Acurate TA bioprosthesis (Symetis, Ecublens, Switzerland).
April 03, 2018 Drs. Al-Amodi, St-Amand, Chu, and colleagues, describe a technique of combined transcatheter aortic valve replacement (TAVR), off-pump single coronary artery bypass, and percutaneous coronary intervention (PCI) in a high-risk patient presenting with unstable angina and severe heart failure.
