[Validity of some electrocardiographic criteria in left ventricular hypertrophy].

The aim of the study was the assessment of the sensitivity, specificity and accuracy of some ECG criteria of left ventricular hypertrophy (LVH). Left ventricular mass (LVM) measured on the M-mode echogram of the left ventricle was the reference standard. Ninety-four (94) unselected, consecutive clinical patients (34 women, 60 men, average age 47 years) underwent in the same day, ECG and echocardiogram. Exclusion criteria were the presence of ischemic heart disease, atrial fibrillation and Wolff-Parkinson-White syndrome. The ECG tracings were interpreted independently by 2 investigators following 5 independent criteria of LVH: 1) Sokolow-Lyon voltage criterion (SL); 2) a modified Romhilt-Estes point score (REM); 3) left atrial abnormality (LAA); 4) left ventricular strain; 5) a new voltage criterion RaVL + SV3 corrected by sex and age. The left ventricular M-mode echograms were recorded using a left parasternal approach and were interpreted independently by 2 investigators. LVM was measured using the "Penn convention" and taking the R wave peak as end-diastole. The prevalence of LVH (= LVM 215 g) in the study population was 47%. The following results were achieved (sensitivity, specificity, accuracy): SL: 68.2%, 84%, 76.6%; REM: 63.6%, 90%, 77.7%: LAA: 36.4%, 84%, 61.7%; strain 52.3%, 72%, 62.8%; RaVL + SV3: 54.5%, 82%, 69.1%. Our data suggest: 1) the high sensitivity, specificity and accuracy of Romhilt-Estes point score are confirmed; 2) the sensitivity of Sokolow-Lyon voltage criterion is reevaluated; 3) the most sensitive morphological criterion seems to be the left ventricular strain; 4) a new voltage criterion could be useful.

Angulated transverse tomographic sections to measure cardiac dimensions by magnetic resonance imaging: a comparison with 2D-echocardiography.

Magnetic resonance imaging (MRI) has shown low accuracy in measuring cardiac dimensions in normal subjects, when transverse tomographic sections are used in comparison with 2D-echocardiography. The rationale of this study was to compare cardiac dimensions in 19 volunteers based on angulated (30 degrees caudo-cranial) transverse tomographic sections both in MRI and 2D-echo. Since the planes investigated by both techniques are superimposable, highly significant correlated Ao, LA, IVS, LW, LV, and RV dimensions are observed. Standardized MRI tomography permits reduction of total examination time and assures repeatability. Thus, using the method reported here, cardiac dimensions in humans might be obtained accurately by MRI.

[Rhabdomyoma of the left atrium. A rare case of mitral valve congenital obstruction simulating hypoplastic left heart syndrome. Echocardiographic diagnosis].

The AA. describe the clinical, surgical and pathological features of a 13-days old infant with multiple cardiac rhabdomyomas diagnosed by two-dimensional echocardiography (2DE). The clinical picture simulated hypoplastic left heart syndrome (HLHS). 2DE showed a well developed left heart. The apical four chamber view disclosed a mass of echoes between the left atrium and ventricle, across the mitral valve. Another little mass of echoes was attached to the left surface of the ventricular septum. The other cardiac chambers and the great arteries were normal. These multiple intracardiac masses were interpreted as rhabdomyomas. The infant underwent an operation at the age of 21 days because of mitral valve obstruction and CHF. At surgery, a left atrial rhabdomyoma was found, that severely obstructed the mitral valve orifice. Although after resecting the tumour we felt that the obstruction was adequately relieved, the little patient died of pulmonary oedema one hour after surgery. At autopsy all the previously detected myomas were confirmed and a small additional one was discovered within the crista supraventricularis. Unexpectedly, the chordae tendineae of the mitral valve were extremely short. This anomaly, masked preoperatively by the rhabdomyoma, was probably the cause of the fatal postoperative mitral regurgitation.

[Hypertrophic obstructive cardiomyopathy associated with significant coronary artery stenosis. Apropos of 2 cases. Diagnostic and therapeutic considerations and review of the literature].

Hypertrophic obstructive cardiomyopathy (HOCM) is rarely associated with significant coronary artery stenosis. Differential diagnosis may be difficult because of similar symptoms; therefore we suggest coronary arteriography in all patients above 30 years of age having HOCM and angina associated. Obviously, in case the clinical diagnosis is coronary artery occlusive disease, left ventriculography is mandatory to rule out HOCM. Four medical treatment beta-blocking agents are the drugs of choice associated, if needed, with coronary dilators, avoiding nitrates. In case surgical treatment is selected, complete correction of all lesions is indicated.
