Systolic time intervals as simple echocardiographic parameters of left ventricular systolic performance: correlation with ejection fraction and longitudinal two-dimensional strain

European Journal of Echocardiography (2010)

Patricia Réant Marina Dijos Erwan Donal Aude Mignot Philippe Ritter

AimsConventionally, the evaluation of left ventricular (LV) systolic function is based on ejection fraction assessment, which may be supplemented by other echocardiographic techniques, such as tissue Doppler imaging, 3D evaluation, and speckle tracking strains. However, these imaging modalities have a high technicity and are time-consuming, while being associated with reproducibility limitations. In this context, the usefulness of simpler measurements such as systolic time intervals (STI) by pulsed Doppler echocardiography must be emphasized.

Pacemaker Endocarditis: Clinical Features and Management of 60 Consecutive Cases

Pacing and Clinical Electrophysiology (2007)

Pierre‐Laurent Massoure Sylvain Reuter Stéphane Lafitte Julien Laborderie PIERRE BORDACHARD

The incidence of endocarditis related to pacemakers is increasing, while the diagnosis and management remain difficult. The objective of this study was to evaluate the clinical features and management of endocarditis after implantation of pacemakers (PM) or cardioverter defibrillators (ICD).We analyzed the hospital course of 60 consecutive patients (48 men, mean age 68 +/- 12 years) admitted to our center for PM (n = 59) or ICD (n = 1) endocarditis between 1998 and 2004.Fever (78%), asthenia (65%), and local symptoms (35%) were common. Positive cultures were obtained in 53 cases (Staphylococcus 89%). Sixteen patients (27%) had pulmonary embolism. Vegetations (mean size 15.2 +/- 8 mm, range 5 to 35 mm) were found in 54 cases (90%), with transthoracic echocardiography in 26 cases (43%), and transesophageal echocardiography (TEE) in 50 cases (89% of the 56 patients who had TEE). Devices were removed surgically (n = 20) or percutaneously (n = 37). In the surgical group, vegetations were larger (17.9 +/- 7 mm vs 13.2 +/- 7 mm, P = 0.01). After removal, 42 patients (70%) had a new PM. Mortality factors (6 deaths - follow up 3.4 +/- 2 years) were the number of vegetations and absence of extraction of the device (P < 0.02). Clinical features and management of the 37 patients with early onset endocarditis (within 1 year after implantation) did not differ from those with late onset.PM endocarditis was essentially staphylococcal. TEE was required for the diagnosis of vegetations. Complete removal of the device is required and associated with a favorable outcome.

Chronic atrial fibrillation ablation impact on endocrine and mechanical cardiac functions

European Heart Journal (2007)

F. Sacher J.-B. Corcuff Philippe Schraub V. Le Bouffos A. Georges

Assess the impact of persistent/permanent atrial fibrillation (AF) ablation on endocrine and mechanical cardiac functions.In all, 43 patients (40 males, 53 +/- 12 years) undergoing persistent/permanent AF ablation had atrial (ANP) and brain natriuretic peptide (BNP) measurements before day 1, 3, and 3 months after ablation. In the same period of time transthoracic echocardiography was performed. With a mean radiofrequency delivery of 98 +/- 29 min, sinus rhythm (SR) was restored in 30 patients (70%) without DC shock. ANP decreased significantly (P < 0.001) with restoration of SR and then increased until day 3 post ablation without reaching the level observed during AF. At 3 months, ANP was significantly lower than day 3 reaching normal value in 28 (65%) patients and being <7 pg/mL in 4 (9%). The BNP followed the same trend with normal BNP level in 23 (53%) patients at 3 months. Identifiable atrial filling waves on the pulsed Doppler transmitral recordings performed between day 2 and day 4 after the procedure were seen in 18 patients (42%). At 3 months, 39 (95%) of the patients with SR during echocardiography had a significant A wave.SR following persistent/permanent AF ablation is associated with a dramatic decrease in natriuretic peptides. At 3 months, despite relatively extensive atrial ablation, endocrine and mechanical cardiac functions are significantly improved.

[Effects of verapamil and nifedipine on blood pressure during rest and exertion and on left ventricular hypertrophy].

PubMed (1992)

Philippe Gosse Raymond Roudaut M Dallocchio

The effects of 6 months treatment with nifedipine 20 mg SR (N) or verapamil 240 mg SR (V) on rest and exercise BP and left ventricular mass (LVM) and function were evaluated in 31 essential hypertensive patients (mean age: 54, 19 males, 12 females), never treated with calcium antagonist. After a 15 days placebo run in, BP was measured at rest and during a maximal bicycle exercise test (stages: 30 watts, 3 min). 2D guided M mode echocardiography and pulsed Doppler allowed assessment of left ventricular mass (Devereux's formula) and function (fractional shortening FS, peak early (E) and late (A) velocities of LV filling). Patients were randomised to N (n = 18) or V (n = 13) and reassessed 6 months later. All echo-Doppler recordings were read blindly by 2 observers.rest BP was similarly reduced in both groups (V: 148 +/- 12/88 +/- 5 vs 162 +/- 10/101 +/- 7; N: 148 +/- 15/90 +/- 7 vs 170 +/- 14/101 +/- 8), as well as exercise maximal BP (V: 224 +/- 32/93 +/- 11 vs 243 +/- 21/104 +/- 11; N: 206 +/- 27/90 +/- 10 vs 231 +/- 17/97 +/- 8). The duration of exercise was significantly increased with V (15 +/- 5 min vs 12 +/- 4, p < 0.05) and insignificantly decreased with N (11 +/- 2 vs 12 +/- 3). Left ventricular mass was higher in V group at entry and was significantly more reduced with V (250 g +/- 74 vs 302 g +/- 92, p < 0.01) than with N (225 g +/- 54 vs 234 g +/- 69).(ABSTRACT TRUNCATED AT 250 WORDS)

[Thrombosis of valvular prostheses: the role of medical treatment].

Archives des maladies du coeur et des vaisseaux (2006)

Raymond Roudaut M E Lorient-Roudaut Sophie Lafitte Stéphanie Brette

Thromboses of valvular prostheses represent a rare but serious complication for mechanical valves, and are sometimes fatal. Obstructive thromboses present an immediate threat to life, while the more common, more insidious, non-obstructive thromboses are essentially manifested by thrombo-embolic events. These thromboses often occur at times of insufficient anticoagulation, especially during the first post-operative year and during treatment breaks for non-cardiac surgery, an increasingly common situation. The therapeutic management of an 'obstructive' thrombosis is above all surgical. However, fibrinolysis represents an effective alternative, although it does present a not insignificant risk of systemic embolism (in the order of 10 to 15%). The main indications for fibrinolysis are thromboses of right heart valves, and for left heart prostheses, patients in a very unstable haemodynamic state, remoteness from a cardiac surgery centre, any surgical contraindications, and cases where a large thrombus has been excluded by trans-oesophageal ultrasound. In cases of contraindications to both surgery and fibrinolysis, treatment with heparin might be proposed, but without any great hopes of completely unblocking the prosthesis. Treatment of a 'non-obstructive' thrombosis is primarily medical: optimising anticoagulation with intravenous heparin, or even the addition of aspirin. When the thrombus is large and mobile, surgery should be envisaged if medical treatment fails.
