Evaluation of Papillary Muscle Function Using Cardiovascular Magnetic Resonance Imaging in Mitral Valve Prolapse
Abnormal traction and excursion of the papillary muscle (PM) can be observed in patients with mitral valve prolapse (MVP) and can adversely affect the electrophysiologic stability of the underlying myocardium….
Hakki’s Formula for Measurement of Aortic Valve Area by Magnetic Resonance Imaging
Hakki’s formula (simplified Gorlin formula) can be used during cardiac catheterization to calculate the stenosed cardiac valve areas and can also be adapted to magnetic resonance imaging (MRI) to measure…
Usefulness of Short-Term Variability of QT Intervals as a Predictor for Electrical Remodeling and Proarrhythmia in Patients With Nonischemic Heart Failure
The high incidence of sudden cardiac death in heart failure (HF) reflects electrophysiologic changes in response to myocardial failure. We previously showed that short-term variability of QT intervals (STV QT…
Prosthesis–Patient Mismatch After Transcatheter Aortic Valve Implantation With the Medtronic CoreValve System in Patients With Aortic Stenosis
A prosthesis–patient mismatch (PPM) is present when the prosthetic valve is too small in relation to the patient’s body size. The purpose of the present study was to investigate the…
Spectrum and Clinical Significance of Systolic Function and Myocardial Fibrosis Assessed by Cardiovascular Magnetic Resonance in Hypertrophic Cardiomyopathy
In hypertrophic cardiomyopathy (HCM), the clinical significance attributable to the broad range of left ventricular (LV) systolic function, assessed as the ejection fraction (EF), is incompletely resolved. We evaluated the…
Do Calcium Channel Blockers Increase the Diagnosis of Heart Failure in Patients With Hypertension?
Calcium channel blockers (CCBs) are widely used to control hypertension. Previous work suggested that their use could increase heart failure (HF), which is 1 of the consequences of uncontrolled hypertension….
Is Detection of Hibernating Myocardium Necessary in Deciding Revascularization in Systolic Heart Failure?
Although the prognosis of systolic heart failure, also called heart failure with reduced ejection fraction, has improved with advances in therapy, the prognosis remains poor in patients who become refractory…
Relation of Baseline High-Sensitivity C-Reactive Protein Level to Cardiovascular Outcomes With Rosuvastatin in the Justification for Use of Statins in Prevention: An Intervention Trial Evaluating Rosuvastatin (JUPITER)
In the Justification for Use of statins in Prevention: an Intervention Trial Evaluating Rosuvastatin (JUPITER), random allocation of rosuvastatin compared to placebo among primary prevention patients with a low-density lipoprotein…
Predictive Value of Total Atrial Conduction Time Estimated With Tissue Doppler Imaging for the Development of New-Onset Atrial Fibrillation After Acute Myocardial Infarction
Patients who develop new-onset atrial fibrillation (AF) after acute myocardial infarction (AMI) show an increased risk for adverse events and mortality during follow-up. Recently, a novel noninvasive echocardiographic method has…
