William J. Stewart mainly investigates Internal medicine, Cardiology, Surgery, Mitral regurgitation and Mitral valve.
His Internal medicine and Doppler echocardiography, Aortic valve, Regurgitation, Valve replacement and Stroke volume investigations all form part of his Internal medicine research activities.
His study explores the link between Doppler echocardiography and topics such as Valvular regurgitation that cross with problems in Proximal isovelocity surface area, Flow convergence, Volume overload and Etiology.
His biological study spans a wide range of topics, including Severity of illness and Systole, Diastole.
His Surgery study combines topics from a wide range of disciplines, such as Stenosis and General surgery.
His biological study deals with issues like Ventricular pressure, which deal with fields such as Afterload, Ventricular hypertrophy, Left ventricular hypertrophy, Mitral valve replacement and Predictive value of tests.
His most cited work include:
- Recommendations for chamber quantification: a report from the American Society of Echocardiography's Guidelines and Standards Committee and the Chamber Quantification Writing Group, developed in conjunction with the European Association of Echocardiography, a branch of the European Society of Cardiology. (9277 citations)
- Recommendations for evaluation of the severity of native valvular regurgitation with two-dimensional and doppler echocardiography (3321 citations)
- Guidelines for performing a comprehensive transesophageal echocardiographic examination: recommendations from the American Society of Echocardiography and the Society of Cardiovascular Anesthesiologists. (551 citations)
What are the main themes of his work throughout his whole career to date?
The scientist’s investigation covers issues in Internal medicine, Cardiology, Surgery, Mitral regurgitation and Mitral valve.
All of his Internal medicine and Stenosis, Doppler echocardiography, Regurgitation, Valve replacement and Aortic valve investigations are sub-components of the entire Internal medicine study.
The study of Cardiology is intertwined with the study of Radiology in a number of ways.
The study incorporates disciplines such as Aortic valvuloplasty and Cardiopulmonary bypass in addition to Surgery.
The Mitral regurgitation study which covers Atrial fibrillation that intersects with Anesthesia.
His research in Mitral valve tackles topics such as Hemodynamics which are related to areas like Pulmonary vein.
He most often published in these fields:
- Internal medicine (78.66%)
- Cardiology (78.66%)
- Surgery (32.64%)

In recent papers he was focusing on the following fields of study:
William J. Stewart spends much of his time researching Cardiology, Internal medicine, Surgery, Stenosis and Valve replacement.
His study in Aortic valve replacement, Ejection fraction, Mitral regurgitation, Heart failure and Aortic valve falls under the purview of Cardiology.
William J. Stewart integrates many fields in his works, including Internal medicine and In patient.
He combines subjects such as Meta-analysis, Anesthesia, Cohort and Aortic valvuloplasty with his study of Surgery.
His work deals with themes such as Coronary artery disease, Randomized controlled trial, Cohort study and Cardiac catheterization, which intersect with Stenosis.
His Valve replacement study integrates concerns from other disciplines, such as Transcatheter aortic, Survival rate and Stroke.

William J. Stewart mostly deals with Cardiology, Internal medicine, Surgery, Valve replacement and Stenosis.
His Cardiology research is multidisciplinary, relying on both Doppler echocardiography and Magnetic resonance imaging.
In his study, William J. Stewart carries out multidisciplinary Internal medicine and Mass index research.
His Mitral regurgitation, Physical examination and Sedation study, which is part of a larger body of work in Surgery, is frequently linked to Certification, bridging the gap between disciplines.
His Valve replacement study combines topics in areas such as Conventional PCI, Aortic valve replacement, Transcatheter aortic, Coronary artery disease and Aortic valve stenosis.
His Stenosis research is multidisciplinary, incorporating perspectives in Ejection fraction, Aortic valve and Percutaneous coronary intervention.
