[Clinical practice guidelines of the Spanish Society of Cardiology on echocardiography].

Doppler echocardiography has become the technique of choice for the diagnosis and follow-up of most heart diseases its main advantages are that it is non-invasive, easy to use, readily available, rapid and has a high cost-benefict ratio. Multiple studies have demonstrated the accuracy of the technique in the diagnosis and severity quantification of the severity of different diseases. Nevertheless, its main limitation lies in the fact that results are operator dependent, and therefore correct training of the echocardiographer is mandatory. In addition, adequate infrastructure and appropriate equipment are a required guarantee quality of the study. Finally, the technique should be used for the indications, in which beneficial information can be yielded. The aim of the present article was to define and update these considerations to enhance the usefulness of echocardiography in clinical practice.

[Rupture of type A aortic dissection into right cardiac cavities].

We present three cases of communication between the false channel of an ascending aortic dissection and a right cardiac chamber in three patients that had previously been operated on for aortic valve replacement. In two cases there already was a degree of aortic dissection at the moment of surgery. Diagnosis was confirmed by transesophageal echocardiography and/or aortography. Two patients developed severe cardiac failure and underwent surgery, while the other one is surviving with medical treatment.

[The usefulness of transesophageal echocardiography in assessing mechanical mitral prostheses. A comparison with transthoracic echocardiography].

One hundred and sixty mechanical mitral prostheses were studied by transoesophageal echocardiography to ascertain the role of this technique in their functional assessment. All patients underwent transoesophageal echocardiogram, and, in 83, transthoracic Doppler-echocardiogram had already been performed immediately prior to transoesophageal echocardiogram. Prostheses presenting structural anomaly on bidimensional image and/or areas of regurgitation with predominantly turbulent flow on colour Doppler were considered to be dysfunctional. Of the 160 prostheses, 115 were considered normofunctional, and regurgitation was detected in 85 (94%) by transoesophageal echocardiogram and 10 (9%) by transthoracic echocardiogram; haemodynamic and/or surgical confirmation was obtained in 6 of these prostheses and all proved to be functioning normally. Of the 45 remaining prostheses considered to be dysfunctional, haemodynamic and/or surgical confirmation was obtained in 21 (the non-confirmed 24 were excluded from the study). Seventeen of the dysfunctional prostheses presented with areas of regurgitation of 3.9-24 cm2 (mean: 9.21 + 5.36); in one case, the degree of regurgitation with respect haemodynamic study was over-assessed; transthoracic echocardiogram detected only periprosthetic leaks in 38% of cases, with areas of regurgitation of 1.8-6.3 cm2 (mean: 1.87 + 2.02). The other 4 dysfunctional prostheses presented dysfunction due to thrombosis; all 4 were diagnosed by both transthoracic and transoesophageal echocardiogram. Transoesophageal echocardiogram detected 12 structural anomalies (1 vegetations, 4 thromboses and 7 dehiscencies), whereas transthoracic echocardiogram only detected these anomalies in five of the cases (1 vegetations and 4 thromboses). Transoesophageal echocardiography surpasses transthoracic echocardiography in the assessment of mechanical mitral prostheses and dysfunction diagnosis.(ABSTRACT TRUNCATED AT 250 WORDS)

[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.

Echocardiographic findings in pannus ingrowth on an omniscience mitral prosthesis.

Serial echocardiographic findings in a patient with an Omniscience mitral prosthesis presenting progressive perivalvular pannus ingrowth are described. The first echocardiographic study was carried out one year after prosthesis implantation and showed decreased prosthetic opening velocity. As prosthetic thrombosis was suspected, hemodynamic study was performed, which proved normal. The patient remained in functional grade II for a year and a half prior to the onset of progressive dyspnea and dizzy spells. Echocardiogram was thus repeated and revealed the presence of multiple dense echoes behind the prosthetic disc. Three months after this last study, the patient presented acute pulmonary edema and reduction of disc excursion and opening and closing velocities. Hemodynamic study suggested prosthetic obstruction. Surgery revealed the presence of perivalvular pannus trapping the prosthetic disc. The prosthesis was subsequently replaced by a Björk-Sorin. This case emphasizes the usefulness of echocardiography in the early detection of perivalvular pannus ingrowth revealing prosthetic mobility anomalies, even before hemodynamic changes occur.

[Bird breeder's lung in children].

A case of hypersensitivity pneumonitis due to pigeon-dropping antigens is reported in a 9 year old girl, and compared with other seven previous reports in children. The insidious nature of this disease, as well as the importance of detailed environmental information in children with unexplained respiratory disease are emphasized. In this case, lung function tests showed a classic restrictive ventilatory defect, and a serious obstructive ventilatory defect evidenced in the narrowing of the smaller airways, and a reduction in the forced expiratory flow at small lung volumes. Hypersensitivity pneumonitis is a lung disease that results from sensitization by inhalation of a variety of organic dusts. Patients usually have circulating antibodies against the etiologic agents. Most patients with this disease also have sensitized T-cells to these agents. Long-term exposure can lead to irreversible lung disease. The histopathologic features are chronic interstitial and alveolar inflammation frequently accompanied by a granulomatous response. The most common symptomatic features are fever, chills and dyspnea 4 to 8 hours after exposure. Antibody activity to antigens is detected in the serum of both symptomatic and asymptomatic breeder's lung. Cellular hypersensitivity to antigens is demonstrated "in vitro" with peripheral lymphocyte populations in almost all symptomatic patients.
