Dynamic cardiomyoplasty for long-term cardiac assist.

European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery

Chachques JC, Acar C, Portoghese M, Bensasson D, Guibourt P, Grare P, Jebara VA, Grandjean PA, Carpentier A.
PMID: 1485974
Eur J Cardiothorac Surg. 1992;6(12):642-7; discussion 647-8. doi: 10.1016/1010-7940(92)90188-4.

The principle of cardiomyoplasty is long-term electrostimulation of a latissimus dorsi muscle (LDM) wrapped around the failing heart. Technically, this procedure consists of placing the left LDM flap around the heart via a window created by partial resection of...

A case of pediatric cardiomyopathy with severely restrictive physiology.

Heart and vessels

Nishikawa T, Tanaka Y, Sasaki Y, Kawataki M, Miyazawa Y, Yasui S, Takarada M, Kasajima T.
PMID: 1487458
Heart Vessels. 1992;7(4):206-10. doi: 10.1007/BF01744606.

A rare case of a 6-year-old male with idiopathic familial cardiomyopathy manifesting severely restrictive physiology is reported. The patient showed congestive heart failure with dilatation of both atria with a normal ventricular cavity. A square-root configuration was revealed in...

The case for echocardiography in acute myocardial infarction.

Journal of the American Society of Echocardiography : official publication of the American Society of Echocardiography

Parisi AF.
PMID: 3078546
J Am Soc Echocardiogr. 1988 May-Jun;1(3):173-8. doi: 10.1016/s0894-7317(88)80072-5.

Acute myocardial infarction occurs after a period of profound myocardial ischemia. Ischemia of this degree immediately produces a regional contraction abnormality, which is readily detectable by echocardiography before the onset of necrosis. Echocardiography has been used both experimentally and...

Cardiac mechanics in the stage-16 chick embryo.

Journal of biomechanical engineering

Taber LA, Keller BB, Clark EB.
PMID: 1487893
J Biomech Eng. 1992 Nov;114(4):427-34. doi: 10.1115/1.2894091.

A theoretical model is presented for the tubular heart of the stage-16 chick embryo (2.3 days of a 21-day incubation period). The model is a thick-walled, pseudoelastic cylindrical shell composed of three isotropic layers: the endocardium, the cardiac jelly,...

Improved cardiac gating and ventilation timing in animal experiments.

Magnetic resonance in medicine

Pruski JC, Abduljalil A, Robitaille PM.
PMID: 1461116
Magn Reson Med. 1992 Oct;27(2):329-37. doi: 10.1002/mrm.1910270212.

In this work we present an improved solution for cardiac gating and ventilation timing in in vivo spectroscopic and imaging experiments. This approach makes use of a pulse conditioner to extract primary timing signals from noisy and fluctuating input...

Fomichev VI, Smirnov VV, Fedoseev AN, Zhukova NA.
PMID: 1490564
Gematol Transfuziol. 1992 Sep-Oct;37(9):19-21.

The myocardial contractile function and microcirculation were studied in 39 patients with angina of effort, III-IV FC before and after plasmosorption course treatment in the presence of drug therapy. A positive clinical effect was recorded in 86% of cases...

Effects of beta-adrenergic blockade on papillary muscle function and the beta-adrenergic receptor system in noninfarcted myocardium in compensated ischemic left ventricular dysfunction.


Warner AL, Bellah KL, Raya TE, Roeske WR, Goldman S.
PMID: 1330362
Circulation. 1992 Nov;86(5):1584-95. doi: 10.1161/01.cir.86.5.1584.

BACKGROUND: beta-Adrenergic receptor blockade has been reported to improve hemodynamics and beta-adrenergic receptor-adenylate cyclase function in idiopathic dilated cardiomyopathy. The purpose of this study was to determine the effects of beta-adrenergic receptor blockade on the beta-adrenergic receptor system and...

PMID: 1337808
Z Kardiol. 1992;81:23-31.

In heart failure, the sympathetic nervous system is activated. The increased release of norepinephrine from the heart and the elevated levels of circulating catecholamines produce a downregulation of myocardial beta 1-adrenoceptors. In ischemic cardiomyopathy and mitral valve disease, a...

Description of the deformation of the left ventricle by a kinematic model.

Journal of biomechanics

Arts T, Hunter WC, Douglas A, Muijtjens AM, Reneman RS.
PMID: 1400512
J Biomech. 1992 Oct;25(10):1119-27. doi: 10.1016/0021-9290(92)90068-c.

A model of left ventricular (LV) kinematics is essential to identify the fundamental physiological modes of LV deformation during a complete cardiac cycle as observed from the motion of a finite number of markers embedded in the LV wall....

Král J, Hradec J, Limanová J.
PMID: 1304451
Cor Vasa. 1992;34(2):108-14.

The paper examines the basic pathophysiologic mechanisms playing a role in the development of cardiovascular changes on thyroid hyper- and hypofunction. The haemodynamic changes typically associated with increased and decreased secretion of thyroid hormones are described and compared. Using...
