[Intraventricular transient obstruction related to bronchodilator treatment].

A 66-year-old woman with a previous history of chronic lung disease, without evidence of heart disease and without signs of left ventricular hypertrophy developed a dynamic intraventricular obstruction documented by a Doppler-derived gradient of 25 mmHg and by physical signs consisting of a brisk carotid pulse and a harsh systolic murmur while she was on treatment with theophylline and hexoprenaline. Both physical signs and Doppler-derived gradient disappeared after withdrawal of bronchodilator drugs.

[Myocardial damage caused by electrical cardioversion].

The possible myocardial injury induced by electrical cardioversion in the treatment of supraventricular arrhythmias was analyzed after 45 countershocks of 200 joules and after 6 of 600 joules (total accumulated energy). In all patients myocardial injury was evaluated by serial CK, CK-Mb, and myoglobin determinations and in 48 cases a cardiac gammagraphy with technetium pyrophosphate was also performed. Significant increases in total CK and myoglobin were observed in 2 (4%) patients treated with 200 joules and in 3 (50%) patients receiving 600 joules. CK-Mb was also increased in one patient receiving 200 joules (13.5 U/I) and in one patient treated with 600 joules (27.8 U/I). In all cases technetium gammagraphy was negative.

[Spontaneous echocardiographic contrast in the left ventricle related to aortic insufficiency].

A case of spontaneous echocardiographic contrast in the left ventricle of a patient with severe aortic insufficiency is presented. This contrast appeared through the mitral valve which opened mainly during tele-diastole. Pulsed Doppler showed the blood flow responsible was laminar and of normal velocity. The mechanism of spontaneous intraventricular contrast cannot be attributed to poor left ventricle function or to high-velocity turbulent flow. We believe that spontaneous contrast was triggered by the decrease in proto-diastolic mitral flow secondary to aortic insufficiency. Transient stagnation of blood in the left atrium might modify the echogenic characteristics of the blood which persist during the passage of the flow through the left ventricle.

[Electrical cardioversion after quinidine administration].

The aim of the present study was to investigate the influence of quinidine on the effectiveness of electrical cardioversion (CV) for the reversion of supraventricular arrhythmias, the amount of electrical energy necessary for the CV and the possible complications of electrical CV. Initially, 100 CV procedures were allocated to the control group (patients free from the action of any antiarrhythmic drug), and 50 CV to the quinidine group. Quinidine was given as dihydroquinidine C1H at a dose of 500 mg/12 hours since the day before CV. In the last group, 6 (12%) patients reverted to normal sinus rhythm before electrical CV. At the time of electrical CV (100 procedures in the control group and 44 in the quinidine group), the patients who received quinidine required a lower amount of electrical energy, and showed a lower incidence of atrial premature beats as compared with the control group (11.3% versus 28%, p less than 0.05). A similar proportion of patients reverted to sinus rhythm in both groups. We conclude that the administration of quinidine before electrical CV has the following advantages: 1) 12% of patients reverted to normal sinus rhythm before electrical CV; 2) quinidine reduced the amount of electrical energy necessary for the CV, and 3) quinidine reduced the incidence of atrial premature beats after electrical CV. On the other hand, quinidine had no influence on the incidence of ventricular arrhythmias after electrical CV.

[Coronarography using high-flow 5F catheters. Percutaneous technic using the femoral and brachial routes].

In order to validate 5F catheters for assessing ischemic heart disease either by the femoral and the right brachial approaches, we prospectively studied with these catheters 125 patients by means of left ventriculogram and coronary artery angiograms. Twenty-five patients were studied with pigtail and Amplatz catheters using the right brachial approach (group I) and 100 patients were studied by the femoral route with pigtail and Judkins catheters (group II). Results were compared to those obtained in a control group of 100 patients prospectively studied by the femoral route with 8F catheters (group III). The following parameters were analyzed: need to change the initially elected catheter diameter or/and artery approach; technical difficulty for obtaining left ventriculogram, left coronary artery, and right coronary artery angiograms; total time of X-ray exposure; quality image of left ventriculograms; incidence of arterial puncture related hematomas or total arterial occlusion; and duration of local compression after sheath removal. There were no differences between groups I and II except for the arterial compression time (p less than 0.0001), and the X-ray exposure time (p = 0.02); both were longer in patients studied by the brachial approach (group I). Whatever the route used, 5F showed a mild increased difficulty (brachial p = 0.001; femoral p = 0.01), and a mild decreased quality image for left coronary artery (brachial p = 0.006; femoral p less than 0.05). Among patients studied by the femoral route a reduction in mild hematomas (p less than 0.05) and in the arterial compression time (p less than 0.0001) were observed in those studied with 5F catheters.(ABSTRACT TRUNCATED AT 250 WORDS)

[The ergonovine test: an episode of hallucinations].

The ergonovine maleate provocation test for the diagnosis of coronary spasm is widely used in patients with rest angina. A patient who developed an episode of psychotomimetic symptoms after the administration of intravenous ergonovine is presented. This side effect of ergonovine maleate had not been previously reported.

[Function of the right ventricle in interauricular communication in adults].

This study was designed prospectively to analyze the influence of age and operation on right ventricular function in atrial septal defect; 17 patients were studied by means of radionuclide studies performed immediately before and approximately 6 months (5,8 +/- 2,3) after surgery. The pulmonary/systemic flow ratio (Qp/Qs) was determined by first pass technique, and right ventricular ejection fraction and peak filling rate were determined by equilibrium ventriculography. In addition, all patients had preoperative catheterization. According to age, patients were divided in group I (less than 35 years) and group II (greater than or equal to 35 years). Preoperatively, patients in group I, in comparison to group II, had better ejection fraction (48 +/- 8 vs 36 +/- 7; p less than 0.01), and better peak filling rate (3.7 +/- 0.9 vs 2.6 +/- 0.7; p less than 0.01), while Qp/Qs were not significantly different (2.5 +/- 0.8 vs 3.0 +/- 1.6) and pulmonary vascular resistances were less elevated (69 +/- 32 vs157 +/- 95 dynes/sec/cm-5; p less than 0.01). After surgery, right ventricular function did not significatively change in relation to preoperative data in both groups (ejection fraction: 44 +/- 13 and 34 +/- 5, respectively; peak filling rate: 3.3 +/- 1.4 and 2.1 +/- 0.6). We conclude that in atrial septal defect indexes of systolic and diastolic right ventricular function deteriorate with age, these changes being associated with a slight increase in pulmonary vascular resistance without changes of Qp/Qs; right ventricular dysfunction does not tend to improve postoperatively.
