Elhendy A, Schinkel AF, van Domburg RT, Bax JJ, Valkema R, Biagini E, Poldermans D
Purpose: The aim of this study was to ascertain whether stress myocardial perfusion imaging can independently predict long-term mortality. Methods: We studied 1,386 patients with known or suspected coronary artery disease by means of stress 99mTc-tetrofosmin myocardial perfusion tomography. The end point during follow-up was death from any cause. Mortality rates were compared with that in a reference population using calculated age- and gender-specific data in the general population. Results: Me... Abstract

The American journal of cardiology, Volume 98, Issue 3, 6 1 2006, Pages 309-313 Role of calcified spots detected by intravascular ultrasound in patients with ST-segment elevation acute myocardial infarction. van der Hoeven BL, Liem SS, Oemrawsingh PV, Dijkstra J, Jukema JW, Putter H, Atsma DE, van der Wall EE, Bax JJ, Reiber JC, Schalij MJ
Electron beam computed tomographic studies have demonstrated that the extent of intracoronary calcium is related to risk of coronary events. This study was performed to gain further insight into the distribution of focal calcifications and their relation to the site of plaque rupture within the culprit artery in consecutive patients (n = 60) with acute myocardial infarction (AMI) using intravascular ultrasound imaging. Calcifications in the culprit lesion and adjacent segments were classified an... Abstract

Journal of cardiovascular electrophysiology, Volume 17, Issue 6, 1 1 2006, Pages 586-593 Serial reevaluation for ARVD/C is indicated in patients presenting with left bundle branch block ventricular tachycardia and minor ECG abnormalities. Kiès P, Bootsma M, Bax JJ, Zeppenfeld K, van Erven L, Wijffels MC, van der Wall EE, Schalij MJ
Introduction: Diagnosis of arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is based on a set of criteria proposed by the International Task Force (TF) for Cardiomyopathies in 1994. To fulfill these criteria, presence of both electrocardiographic and anatomical abnormalities must be assessed with ECG and imaging techniques, respectively. This may be difficult in patients with early/mild forms of the disease as detectable structural abnormalities may still be absent. We evaluate... Abstract

Objective: The objective of our study was to validate using MDCT for the assessment of right ventricular (RV) function. MDCT with retrospective ECG gating was performed in 15 patients being evaluated for suspected cardiovascular disease. Echocardiography was performed for comparison. The MDCT images were reconstructed at 20 phase points over the cardiac cycle. The end-diastolic and end-systolic volumes of both ventricles were measured. Stroke volumes and ejection fractions were calculated from t... Abstract

European journal of echocardiography : the journal of the Working Group on Echocardiography of the European Society of Cardiology, Volume 8, Issue 3, 23 4 2006, Pages 229-231 Mobile right heart thrombus and massive pulmonary embolism. de Vrey EA, Bax JJ, Poldermans D, van der Wall EE, Holman ER
The current report describes a patient with pulmonary embolism, treated unsuccessfully with heparin. Transthoracic echocardiography revealed free-floating right heart thrombus. Migrating deep vein thrombus to the right heart was suspected. Transesophageal echocardiography confirmed origin of the thrombus in the inferior cava vein. Mortality rate of mobile right heart thrombus is over 40%, therefore urgent surgical embolectomy was performed with relief of symptoms. Abstract

The American journal of cardiology, Volume 98, Issue 2, 19 3 2006, Pages 230-235 Cardiac resynchronization therapy in patients with systolic left ventricular dysfunction and symptoms of mild heart failure secondary to ischemic or nonischemic cardiomyopathy. Bleeker GB, Schalij MJ, Holman ER, Steendijk P, van der Wall EE, Bax JJ
Cardiac resynchronization therapy (CRT) is beneficial in selected patients with moderate to severe heart failure (New York Heart Association [NYHA] classes III to IV). Patients with mildly symptomatic heart failure (NYHA class II) are currently not eligible for CRT and the potential beneficial effects in these patients have not been well studied. Fifty consecutive patients in NYHA class II heart failure and 50 consecutive patients in NYHA classes III to IV (control group) were prospectively incl... Abstract

The American journal of cardiology, Volume 98, Issue 1, 6 1 2006, Pages 111-115 Association of plasma N-terminal pro-B-type natriuretic peptide with postoperative cardiac events in patients undergoing surgery for abdominal aortic aneurysm or leg bypass. Feringa HH, Bax JJ, Elhendy A, de Jonge R, Lindemans J, Schouten O, van den Meiracker AH, Boersma E, Schinkel AF, Kertai MD, van Sambeek MR, Poldermans D
Postoperative cardiac events are related to myocardial ischemia and reduced left ventricular function. The utility of N-terminal-pro-B-type natriuretic peptide (NT-pro-BNP) for preoperative cardiac risk evaluation has not been evaluated. The objective of this study was to assess whether plasma NT-pro-BNP predicts postoperative cardiac events in patients who undergo major vascular surgery in addition to clinical and dobutamine stress echocardiographic data. One hundred seventy consecutive patient... Abstract

Coronary artery disease, Volume 17, Issue 3, 1 1 2006, Pages 255-259 Baseline plasma N-terminal pro-B-type natriuretic peptide is associated with the extent of stress-induced myocardial ischemia during dobutamine stress echocardiography.

Objective: To determine the relationship between baseline plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and the presence and extent of myocardial ischemia during dobutamine stress echocardiography (DSE). Methods: NT-proBNP was measured in 170 consecutive patients prior to DSE. Rest wall motion abnormalities (RWMAs) and new wall motion abnormalities (NWMAs) were scored using a 5-point, 17-segment model. Kruskal-Wallis tests were applied to study differences in NT-proBNP leve... Abstract

Westenberg JJ, Lamb HJ, van der Geest RJ, Bleeker GB, Holman ER, Schalij MJ, de Roos A, van der Wall EE, Reiber JH, Bax JJ
Objectives: This study sought to compare tissue Doppler imaging (TDI) with velocity-encoded (VE) magnetic resonance imaging (MRI) for left ventricular (LV) dyssynchrony assessment. Background: Cardiac resynchronization therapy (CRT) is proposed for patients with heart failure, depressed LV function, and a wide QRS complex. Selection is based mainly on electrocardiogram criteria, but recent data suggest that intraventricular dyssynchrony may be preferred for selection. An LV dyssynchrony can adeq... Abstract

Background: The aim of this study was to assess the accuracy of stress 99m technetium tetrofosmin myocardial perfusion imaging for the diagnosis of in stent stenosis (ISS). Methods: We studied 72 patients who underwent exercise or dobutamine stress 99m technetium tetrofosmin imaging, 0.9+/-0.5 years after percutaneous coronary interventions in which stents were deployed. Coronary angiography was performed within 3 months of the stress test. ISS was defined as > or =50% stenosis in a coronary... Abstract

Introduction: Recent cross-sectional studies have documented an association between acromegaly and regurgitant valvular heart disease. The aim of this study was to evaluate the change in prevalence of valvular heart disease in relation to the clinical activity, because the natural history of valvular changes in acromegaly is unknown. Patients and methods: Valvular regurgitation was assessed in 37 acromegalic patients (18 patients with active disease, and 19 with controlled disease) by convention... Abstract

The number of patients with chronic heart failure is increasing rapidly in the Western world. Despite the introduction of new pharmacologic therapies, the prognosis of these patients remains poor. Left ventricular (LV) dyssynchrony is a frequently observed feature in patients with heart failure, and is recognized as an important predictor of poor outcome if left untreated. The presence of LV dyssynchrony leads to inefficient LV contraction with a decreased cardiac output. Moreover, patients with... Abstract

Two patients recently underwent successful repeat left ventricular anterior aneurysmectomies at our institution. Both patients had undergone a linear repair at first operation. Over time severe heart failure relapsed and echocardiography revealed the recurrence of a voluminous antero-septo-apical aneurysm in both cases, associated with severe mitral regurgitation. Because of still preserved motion of at least three of the basal segments of the left ventricle, a repeat ventriculoplasty according... Abstract
