    Cardiac and Renal Directorate, Barts and the London NHS Trust, 3rd Floor QEII Block, St Bartholomew's Hospital, West Smithfield, London EC1A 7BE, UK.
    The optimum day for discharge after coronary artery bypass graft (CABG) surgery has been subject to some debate yet there has been a steady increase in the number of patients discharged within 5 days of surgery. Delayed discharges may result in the under use of surgical capacity and impact upon patient outcomes. The author conducted a retrospective; correlational study of 333 patients to investigate the variables associated with delayed discharge after CABG. Read More

    Minimally invasive coronary artery bypass grafting in high-risk patients. Late follow-up with assessment of left internal mammary artery graft patency and flow by exercise transthoracic Doppler echocardiography.
    Cardiovasc Surg 2003 Oct;11(5):389-95
    Department of Thoracic and Cardiovascular Surgery, Heinrich-Heine-University, Duesseldorf, Germany.
    Unlabelled: Patients with significant risk factors are at increased risk of higher mortality and morbidity (9-16%) after CABG-procedures with cardiopulmonary bypass (CPB). When catheter interventions are not applicable and conventional CABG with CPB are considered to have an unacceptable perioperative risk, these patients (n=35) were scheduled for minimally invasive coronary artery bypass grafting (MIDCAB).

    Patients And Methods: The risks leading to exclusion of conventional CABG procedures were: extremely impaired LV-function (EF<20%), severe pulmonary diseases, malignant carcinoma, compromised coagulation system, age >80 years with impaired physical constitution, redo-procedures after complicated initial operation, symptomatic descending thoracic aortic aneurysm, ongoing long-term intensive care treatment with unclear prognosis.

    The quality of care for patients with abdominal aortic aneurysms.
    Cardiovasc Surg 2003 Oct;11(5):331-6
    University of Michigan Medical Center, Section of Vascular Surgery, 2210 Taubman Health Care Center, 1500 E. Medical Center Drive, Ann Arbor, MI 48109-0329, USA.
    Abdominal aortic aneurysm (AAA) repair is a complex surgical procedure and is commonly performed in a variety of practice settings across the United States. The quality of surgical care is neither ideal nor uniform across medical centers with documented variation in both utilization and outcomes. Recent data document that screening, though effective in reducing AAA-related deaths, may have only small contributions to population mortality. Read More

    The safety of fibrin sealants.
    Cardiovasc Surg 2003 Aug;11 Suppl 1:23-8
    Global Drug Surveillance, Aventis Behring GmbH, PO Box 1230, D-35002 Marburg, Germany.
    Fibrin sealants are prepared from fibrinogen, thrombin and sometimes also factor XIII that have been purified from human plasma. Bovine aprotinin is also included in some preparations. Each of these components has the potential to carry blood-borne pathogens, albeit at a very low frequency. Read More

    Fibrin sealants in supporting surgical techniques: The importance of individual components.
    Cardiovasc Surg 2003 Aug;11 Suppl 1:17-21
    Department of Vascular Surgery, Knappschafts Hospital, Osterfeldstrasse 157, D-35392 Bottrop, Germany.
    Fibrin sealants have many different uses across a broad range of surgeries, where they have proved successful in controlling bleeding, providing suture support and tissue sealing. The action of all fibrin sealants depends on the thrombin-catalyzed formation of a fibrin clot. However, neither the purity nor the concentration of the main components of fibrin sealants (thrombin and fibrinogen) is uniform across all commercial products and this will affect performance. Read More

    Fibrin sealants in supporting surgical techniques: strength in factor XIII.
    Cardiovasc Surg 2003 Aug;11 Suppl 1:13-6
    Wound Healing, Aventis Behring, King of Prussia, PA 19406-0901, USA.
    Factor XIII has a well-established role in natural coagulation and clot stabilization. It is often added back to fibrin sealants that are used in a wide range of surgical settings to achieve successful hemostasis, tissue adhesion and wound healing. Factor XIII is the final enzyme to be activated in the blood coagulation cascade. Read More

    Fibrin sealants in clinical practice.
    Cardiovasc Surg 2003 Aug;11 Suppl 1:5-11
    Duke University Medical Center, Rm 1112, Green Zone, DUMC 3457, Trent Drive, Durham, NC 27710, USA.
    Fibrin sealants are used in a wide range of surgeries, primarily as hemostatic agents, but also to assist tissue sealing and wound healing. While all fibrin sealants contain fibrinogen and thrombin, they differ in their final composition. This affects the properties of the resulting fibrin clot and may influence their use in different surgical procedures. Read More

    Aortoventriculoplasty in a patient with complex left ventricular outflow tract obstruction, mitral valve stenosis and aneurysm of the ascending aorta.
    Cardiovasc Surg 2003 Aug;11(4):313-5
    Department of Cardiovascular Surgery, Acibadem Hospital, Tekin Sok. No. 8, Accibadem, Istanbul 81020, Turkey.
    We describe a new method of aortoventriculoplasty in a patient with calcified mitral stenosis, aortic valvular stenosis, severe left ventricular outflow tract obstruction, and aneurysm of the ascending aorta. This complex pathology was successfully treated with replacement of both the valves and a tubular dacron graft. The proximal end of the dacron tube was tailored as a patch for the repair of the ventricular septum and the aortic root, and the distal end was anastomosed to the distal ascending aorta. Read More

    The frequency of pleural effusions after Bellovac drainage following coronary bypass grafting.
    Cardiovasc Surg 2003 Aug;11(4):309-12
    Blackpool Victoria Hospital, The Department of Cardiothoracic Surgery, Whinney Heys Road, Blackpool FY3 8NR, UK.
    Background: A common postoperative complication after CABG with internal mammary artery (IMA) harvest is the evolution of a pleural effusion. Our aim was to see if the intra-operative insertion of a Bellovac drain to the pleural cavity, with drainage continuing for 4-days post operation, eliminates the complication of pleural effusion.

    Methods: Using our computerised audit database, 500 consecutive patients were identified who had undergone CABG including at least one internal mammary graft by a single consultant at Blackpool Victoria Hospital. Read More
