ACC/AHA 2006 Guidelines for the Management of Patients With Valvular Heart Disease

To identify the characteristics, treatment, and outcomes of contemporary patients with valvular heart disease (VHD) in Europe, and to examine adherence to guidelines.

Infective Endocarditis in Adults: Diagnosis, Antimicrobial Therapy, and Management of Complications A Scientific Statement for Healthcare Professionals From the American Heart Association

Background—Despite advances in medical, surgical, and critical care interventions, infective endocarditis remains a disease that is associated with considerable morbidity and mortality. The continuing evolution of antimicrobial resistance among common pathogens that cause infective endocarditis creates additional therapeutic issues for physicians to manage in this potentially life-threatening illness. Methods and Results—This work represents the third iteration of an infective endocarditis “treatment” document developed by the American Heart Association under the auspices of the Committee on Rheumatic Fever, Endocarditis, and Kawasaki Disease, Council on Cardiovascular Disease of the Young. It updates recommendations for diagnosis, treatment, and management of complications of infective endocarditis. A multidisciplinary committee of experts drafted this document to assist physicians in the evolving care of patients with infective endocarditis in the new millennium. This extensive document is accompanied by an executive summary that covers the key points of the diagnosis, antimicrobial therapy, and management of infective endocarditis. For the first time, an evidence-based scoring system that is used by the American College of Cardiology and the American Heart Association was applied to treatment recommendations. Tables also have been included that provide input on the use of echocardiography during diagnosis and treatment of infective endocarditis, evaluation and treatment of culture-negative endocarditis, and short-term and long-term management of patients during and after completion of antimicrobial treatment. To assist physicians who care for children, pediatric dosing was added to each treatment regimen. Conclusions—The recommendations outlined in this update should assist physicians in all aspects of patient care in the diagnosis, medical and surgical treatment, and follow-up of infective endocarditis, as well as management of associated complications. Clinical variability and complexity in infective endocarditis, however, dictate that these guidelines be used to support and not supplant physician-directed decisions in individual patient management.

Replacement of aortic and mitral valves with a pulmonary autograft

Homograft replacement of the aortic valve.

Correction of pulmonary atresia with a homograft aortic valve.

Background Pulmonary autograft replacement of the diseased aortic valve has not been widely practiced due to concerns regarding late autograft competence and the consequences of creating pulmonary valve disease. To investigate this, the fate of the pioneering series of patients has been determined. Methods and Results The 131 hospital survivors of the pulmonary autograft operation at the National Heart Hospital from 1967 to 1984 were identified and their outcomes determined to 1994. Age at operation was 11 to 52 years, and 109 patients were male. Autograft implantation was orthotopic subcoronary (107), free-standing root (20), or Dacron mounted (2). In 113 patients, homografts replaced the native pulmonary valve. Ten and 20 years after operation, survival was 85% and 61%, freedom from autograft replacement was 88% and 75%, and freedom from replacement of pulmonary position homografts was 89% and 80%, respectively. Causes of deaths (53) included chronic heart failure (13), complications of reoperation (12), and endocarditis (7). Autograft regurgitation, the most common indication for reoperation, appeared primarily technical in nature, usually due to cusp prolapse. Degeneration was found in only 3 of 30 explanted autografts, and the young patients showed no increase in late valve failure. Homografts outperformed other valve replacements in the pulmonary position, but patients with orthotopic subcoronary and root autografts survived similarly. Conclusions The pulmonary autograft offers low rates of degeneration, endocarditis, and thromboembolism for a period lasting >20 years, particularly in the young, with reoperation mainly required for malpositioning of the autograft cusps. The capacity of the autograft to maintain viability with minimal degeneration is not matched by any other biological valve replacement.
