PURPOSE To establish Canadian guidelines for training in adult perioperative transesophageal echocardiography (TEE). METHODS Guidelines were established by the Canadian Perioperative Echocardiography Group with the support of the cardiovascular section of the Canadian Anesthesiologists' Society (CAS) in conjunction with the Canadian Society of(More)
OBJECTIVES Mitral annular calcification is associated with significant morbidity and mortality at the time of mitral valve surgery. However, few data are available describing the impact of mitral annular calcification on early and late outcomes following mitral valve repair in the current era. METHODS Between 2001 and 2011, 625 patients were referred for(More)
BACKGROUND Chronic thromboembolic pulmonary hypertension represents a unique form of pulmonary hypertension amenable to curative intervention with a pulmonary thromboendarterectomy (PTE). Canada's first successful and sustainable program for PTE surgery was established at the University of Ottawa Heart Institute in 1995. Inclusive results from similarly(More)
The sliding leaflet technique has been used in mitral valve repair in conjunction with posterior leaflet quadrangular resection to avoid left ventricular outflow tract obstruction secondary to systolic anterior motion of the anterior leaflet of the mitral valve. On occasion, despite the use of the sliding leaflet technique, reattachment of the edges of the(More)
Resectable retroperitoneal tumors with right atrial tumor thrombus extension have been excised previously using cardiopulmonary bypass and deep hypothermic circulatory arrest. We have used a technique involving clamping of the descending aorta with avoidance of deep hypothermic circulatory arrest in 6 patients. The approach provided a virtually bloodless(More)
BACKGROUND Percutaneous therapies to manage mitral regurgitation are emerging as an alternative to conventional operations, especially for patients with a high estimated perioperative risk. However, contemporary risk models may not accurately reflect outcomes at reference mitral valve centers. The purpose of this study was to describe perioperative(More)
Papillary fibroelastomas are rare, benign cardiac tumours that most commonly arise from cardiac valves, and often present with signs and symptoms of embolization. A patient presented initially with transient ischemic attacks. He was found to have a papillary fibroelastoma on his tricuspid valve, which was successfully resected. Nine years later, he(More)
BACKGROUND Repair of mitral regurgitation (MR) caused by prolapse has been well validated. Although favorable early and late results after repair have been reported, few data are available that mechanistically describe how a mitral repair fails beyond the mere need for mitral valve reoperation. We therefore sought to determine the modes of valve repair(More)
