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.Consequences of Hybrid Procedure Addition to Robotic-Assisted Direct Coronary Artery Bypass

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.A case of a successful repair of a partially unroofed terminal segment featured in Annals of Thoracic Surgery

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.Innovations publishes left atrial appendage obliteration study by Drs. Chui, Kiaii and colleagues
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.

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 dissectionNew collaborative faculty literature featured in the Canadian Journal of Anesthesia

June 29, 2022
Sutureless aortic valve replacement (AVR) is a wide-spreading new technology that provides short clamping time and excellent hemodynamic outcomes. However, among its possible complications is the risk of paravalvular leak. Drs. Keita Sato, Chris Harle, Bob Kiaii, and their team, present the case of a 63-year-old woman who underwent minimally invasive right mini-thoracotomy AVR with Perceval S sutureless valve (LivaNova, London, UK). Intraoperative transesophageal echocardiography revealed severe paravalvular leak with stent distortion. Rescue balloon valvuloplasty was performed through the right femoral artery, and resulted in the resolution of the paravalvular leak. This case illustrates the utility and feasibility of balloon valvuloplasty in trouble-shooting sutureless aortic valve stent distortion, thus avoiding a repeat aortic cross-clamp and valve replacement.Safety, efficacy, and hemodynamic performance of a stented bovine pericardial aortic valve bioprosthesis: Two-year analysis.
