Comparative Study
Neighbourhood income and cardiac rehabilitation access as determinants of nonattendance and noncompletion.
Despite known benefits of exercise-based cardiac rehabilitation (CR), attendance and completion rates remain low. Our objective was to review attendance and completion of CR overall and by level of neighbourhood income in Saskatoon, Canada and then determine the effect of opening a new CR facility in close proximity to low-income neighbourhoods. ⋯ High rates of nonattendance and noncompletion of CR were observed. Living in a low-income neighbourhood was associated with lower rates of attendance and completion. Expanding access to CR did not increase attendance or completion among patients of low-income neighbourhoods to a significant level.

Physical activity is associated with a lower prevalence of depressive symptoms in cardiac patients. However, the benefits of physical activity on depression perioperatively are unknown. We sought to identify independent parameters associated with depression in patients undergoing cardiac surgery. ⋯ Up to 40% of patients are depressed after cardiac surgery. Preoperative depression and postoperative stressful events were the strongest independent associations postoperatively. Physical inactivity was associated with preoperative depression and new depression 6 months postoperatively.

Not infrequently, chordae tendineae rupture, which was not recognized preoperatively using echocardiography, was found during mitral valve (MV) surgery in patients with severe mitral regurgitation (MR) diagnosed with MV prolapse. We evaluated the incidence and predictors of echocardiographically-unrecognized chordae tendineae rupture in patients with severe MR because of MV prolapse. ⋯ Unrecognized chordae tendineae rupture is a common unrecognized contributor to severe MR necessitating valve replacement in MV prolapse patients. Earlier recognition and more specific management might contribute to improved prognosis for such patients.

There is an ongoing debate whether the tricuspid valve (TV) should be repaired with a suture annuloplasty or a prosthetic ring. ⋯ A modified De Vega suture annuloplasty was effective at eliminating TR and producing right ventricular (RV) reverse remodelling at 5-year follow-up, although TR tends to increase with time.

The junction between the left brachiocephalic vein and the superior vena cava is a high-risk region during lead extraction. Venous laceration with hemodynamic collapse is the most feared complication arising in this region, but arteriovenous fistula formation after excimer laser extraction also has been reported. ⋯ A continuous murmur was heard near the extraction site and invasive angiography demonstrated a left internal mammary artery to the brachiocephalic vein fistula, which was coiled. A new continuous murmur after lead extraction is the hallmark of this rare complication.
