Transcatheter or Surgical Aortic-Valve Replacement in Intermediate-Risk Patients.
BACKGROUND Previous trials have shown that among high-risk patients with aortic stenosis, survival rates are similar with transcatheter aortic-valve replacement (TAVR) and surgical aortic-valveExpand

Abdominal obesity and the metabolic syndrome: contribution to global cardiometabolic risk.
There is currently substantial confusion between the conceptual definition of the metabolic syndrome and the clinical screening parameters and cut-off values proposed by various organizationsExpand

Paradoxical low-flow, low-gradient severe aortic stenosis despite preserved ejection fraction is associated with higher afterload and reduced survival.
BACKGROUND Recent studies and current clinical observations suggest that some patients with severe aortic stenosis on the basis of aortic valve area may paradoxically have a relatively low gradientExpand

Mechanisms, prevention, and treatment of atrial fibrillation after cardiac surgery.
Post-operative atrial fibrillation (POAF) is a frequent complication occurring in 30% to 50% of patients after cardiac surgery. It is associated with an increased risk of mortality and morbidity,Expand

Transcatheter Aortic‐Valve Replacement with a Balloon‐Expandable Valve in Low‐Risk Patients
BACKGROUND Among patients with aortic stenosis who are at intermediate or high risk for death with surgery, major outcomes are similar with transcatheter aortic‐valve replacement (TAVR) and surgicalExpand

Prosthesis-patient mismatch: definition, clinical impact, and prevention
Prosthesis-patient mismatch (PPM) is present when the effective orifice area of the inserted prosthetic valve is too small in relation to body size. Its main haemodynamic consequence is to generateExpand

Acute kidney injury following transcatheter aortic valve implantation: predictive factors, prognostic value, and comparison with surgical aortic valve replacement
Aims Very few data exist on the occurrence of acute kidney injury (AKI) associated with transcatheter aortic valve implantation (TAVI). The objectives of the present study were (i) to determine theExpand

Hemodynamic and clinical impact of prosthesis-patient mismatch in the aortic valve position and its prevention.
Prosthesis-patient mismatch is present when the effective orifice area of the inserted prosthetic valve is less than that of a normal human valve. This is a frequent problem in patients undergoingExpand

Reduced systemic arterial compliance impacts significantly on left ventricular afterload and function in aortic stenosis: implications for diagnosis and treatment.
OBJECTIVES We sought to determine to what extent systemic arterial compliance (SAC) might impact on afterload and left ventricular (LV) function in patients with aortic stenosis (AS). BACKGROUNDExpand

Prosthetic Heart Valves: Selection of the Optimal Prosthesis and Long-Term Management
The introduction of valve replacement surgery in the early 1960s has dramatically improved the outcome of patients with valvular heart disease. Approximately 90 000 valve substitutes are nowExpand
