In elderly, high-risk surgical patients, sutureless aortic valve replacement (AVR) can often be an alternative to conventional AVR; shorter aortic cross-clamp and cardiopulmonary bypass times are the chief advantages. We compared the outcomes of sutureless AVR with those of conventional AVR in 70 elderly patients who underwent concomitant cardiac surgical procedures. We retrospectively analyzed the cases of 42 men and 28 women (mean age, 70.4 ± 10.3 yr; range, 34-93 yr) who underwent cardiac operations plus AVR with either a sutureless valve (group 1, n=38) or a conventional bioprosthetic or mechanical valve (group 2, n=32). Baseline patient characteristics were similar except for worse New York Heart Association functional status and the prevalence of diabetes mellitus in group 1. In group 1, the operative, cross-clamp, and cardiopulmonary bypass times were shorter (all =0.001), postoperative drainage amounts were lower (=0.009), hospital stays were shorter (=0.004), and less red blood cell transfusion was needed (=0.037). Echocardiograms before patients' discharge from the hospital showed lower peak and mean aortic gradients in group 1 (mean transvalvular gradient, 8.4 ± 2.8 vs 12.2 ± 5.2 mmHg; =0.012). We found that elderly, high-risk patients who underwent multiple cardiac surgical procedures and sutureless AVR had better hemodynamic outcomes and shorter ischemic times than did patients who underwent conventional AVR.

GI complications remain a significant concern after cardiac surgery under cardiopulmonary bypass. Higher-risk patients can be identified and treated prophylactically and in the postoperative period.

In patients with respiratory failure and impairment of the left ventricle, arteriovenous extracorporeal membrane oxygenation (ECMO) offers further therapeutic options. Systemic anticoagulation is mandatory and heparin is routinely administrated. However, repeated exposure to heparin may cause heparin-induced thrombocytopenia (HIT) and carries a risk of thrombotic mortality and morbidity. We present a patient who developed HIT during ECMO support and was treated successfully and safely by fondaparinux. Fondaparinux can be used for thromboembolic treatment or prophylaxis in a patient with HIT.

The outcomes of 3 different methods of repair of left ventricular pseudoaneurysm after myocardial infarction were analyzed retrospectively. The operations were carried out in 22 patients between 1985 and 2008. Repair procedures included primary closure with Teflon-pledgeted sutures, and Dacron or pericardial patches. Overall hospital mortality was 27.3% (2 patients had primary closure, 3 had a Dacron patch, and 1 had a pericardial patch). Mean postoperative bleeding was 885 mL (range, 200-4,800 mL). Mean preoperative and postoperative ejection fractions were 40% (30%-47%) and 48% (30%-65%), respectively. The overall incidence of arrhythmia was 36.4% (8 patients). The incidence of arrhythmia was lowest in the pericardial patch group, but this was not statistically significant. No significant differences in postoperative ejection fraction or hemorrhage were found among the study groups. Mean survival was 61.9 + or - 41.4 months in the 16 hospital survivors. Although the 3 techniques gave similar results, repair with an autologous pericardial patch may offer an advantage in terms of less postoperative arrhythmias.

Compartment syndrome is commonly seen following lower extremity ischemia. However, upper extremities' compartment syndrome, especially after any vascular surgical procedures, is infrequent. Herein we report a case of an acute forearm compartment syndrome that was developed after delayed brachial artery embolectomy.
