BACKGROUND Cardiac resynchronization therapy (CRT) by means of simultaneous biventricular pacing improves left ventricular systolic performance and synchrony in patients with heart failure and bundle-branch block. We used tissue tracking and 3D echocardiography to evaluate the impact of sequential CRT with individualized interventricular delay programming. METHODS AND RESULTS Twenty consecuti...
1 S 2012 EHRA/HRS expert consensus statement on cardiac resynchronization therapy in heart failure: implant and follow-up recommendations and management Developed in partnership with the European Heart Rhythm Association (EHRA), A registered branch of the European Society of Cardiology (ESC), and the Heart Rhythm Society; and in collaboration with the Heart Failure Society of America (HFSA), th...
A 74 year old man with dilated cardiomyopathy and right bundle branch block underwent implantation of a biventricular pacemaker for treatment of severe heart failure. When reviewed six weeks later his New York Heart Association functional class had improved from III to I. Using the Sonos 7500 Live 3D system, a real time transthoracic three dimensional echocardiogram was performed in the presenc...
OBJECTIVES We evaluated the use and the impact of echocardiography in patients receiving an initial diagnosis of congestive heart failure in Olmsted County, Minnesota, in 1991. BACKGROUND The American College of Cardiology/American Heart Association clinical practice guidelines recommend echocardiography in all patients with suspected congestive heart failure. No data are available on use and...
To analyze the cost efficiency of guidelines proposed by the European Society of Cardiology for investigation of patients in the community with suspected heart failure (HF). The guidelines recommend electrocardiography (ECG) and/or measurement of N-terminal pro B type natriuretic peptide (NTproBNP) prior to referral for echocardiography. Portable echocardiography is a new but validated techniqu...
BACKGROUND Resynchronization pacing is an effective symptomatic treatment for heart failure patients with prolongation of the QRS duration (QRSd). Dyssynchronous contraction of the left ventricle is also observed with normal QRSd. We set out to determine how electrical activation of the left ventricular (LV) free wall differed between patients with left bundle-branch block (LBBB) and normal QRS...
bifid cardiac apex is a rare anomaly of human hearts. we report of the case of a 34-year-old man with a previous history of ventricular septal defect (vsd) and subvalvular pulmonary stenosis. he had undergone pulmonary commissurotomy and vsd closure 22 years before he was referred to our center for evaluation of progressive dyspnea. transthoracic echocardiography revealed atrial septal defect (...
A 2-year-old girl was referred to the Harapan Kita National Heart Center due return of spontaneous circulation after cardiac arrest, bradyarrhythmia and repeated seizures with loss consciousness. She had been treated an epilepsy drug for 1 year. Electrocardiography during one episode showed complete heart block junctional escape rhythm QT interval prolongation, which then progressed torsades de...
Background Incidence of heart failure with preserved ejection fraction is increasing and putting the emphases on comprehensive evaluation of diastolic function. Furthermore, diastolic dysfunction even in the absence of heart failure has been shown to have prognostic significance. American Society of Echocardiography and European Association of Echocardiography (ASE/EAE) 2-level decision tree us...
