[Aortic valve complications associated with subarterial infundibular ventricular septal defect. Echocardiograpic follow-up].

INTRODUCTION AND OBJECTIVES: Interventricular fibromuscular septal defects of the outlet tract are subarterial infundibular ventricular septal defects (VSDs). This anatomical situation predisposes to aortic cusp prolapse (AoP) and/or regurgitation (AoR). METHODS: In order to determinate the frequency of VSDs and the presence or development of aortic valve alterations detected by two-dimensional echocardiography, we studied 35 patients with VSDs. The defect area and presence, severity, and evolution of AoP and/or AoR were evaluated. Ten anatomic specimens were studied to verify the echocardiographic correlation. RESULTS: Subarterial infundibular defect was present in 6.9% of all ventricular septal defects. The average age at time of diagnosis was 5,8 years. VSDs diameter and gradient did not change during follow-up. At time of diagnosis, 30 patients (87%) did not have AoR, but during an average follow-up of 8 years, 11 (32%) developed it. By the end of the study, 46% had AoR. When the time to progression of AoR was compared in the group that developed it versus the group that did not, the median values were similar in both groups. There was a greater tendency to development and/or progression of regurgitation in small VSDs. The echo-anatomic correlation was precise. CONCLUSIONS: Aortic valve damage was a frequent finding in VSD. Most cases did not progress to more severe AoR. Small VSDs developed more severe regurgitation in less time. Surgery must be considered when AoR is detected. Regular evaluation by echocardiography is important in follow-up.

Echocardiographic Evaluation of Patients with Primary Pulmonary Hypertension Before and After Atrial Septostomy.

OBJECTIVES: To characterize the early changes in right ventricular [right ventricle (RV)] geometry and function, as assessed by two-dimensional (2-D) and Doppler echocardiography, after balloon-dilation atrial septostomy (BDAS) in patients with severe primary pulmonary hypertension (PPH). BACKGROUND: Survival in PPH is to a great extent dependent on the functional status of the RV. BDAS recently has been shown to improve functional class and hemodynamics in patients with PPH nonresponsive to conventional vasodilator treatment. METHODS: Ten patients with severe PPH who underwent BDAS were studied with transthoracic and transesophageal 2-D and Doppler echocardiography. RV dimensions were measured in the apical four-chamber view. Continuous-wave Doppler echocardiography was used to obtain peak velocity of tricuspid regurgitation. Transesophageal echocardiography (TEE) primarily was used for the follow-up of the atrial septal defects (ASDs). RESULTS: In the early post-BDAS studies, right atrial and ventricular dimensions significantly decreased in all patients (P < 0.05). Global right ventricular wall motion (RVWM) also improved. RV percent change in area after septostomy inversely correlated with the changes in RV systolic area (r = -0.75; P < 0.05) and also with the baseline (preprocedure) values of RV percent change in area (r = -0.77; P < 0.05). Neither RV wall thickness nor the degree of tricuspid regurgitation were modified significantly after the procedure. CONCLUSIONS: BDAS in the setting of severe PPH results in moderate and salutary changes in geometry and function of the RV as assessed by 2-D echocardiography. These changes mainly appear to be the result of the decompression effect of atrial septostomy.

[Dynamic echocardiography in coronary risk stratification].

The prognostic value of some coronary risk factors related to Stress/Echocardiography was analyzed. The most important prognostic factors during an abnormal study are: presence and time of beginning, severity and extension of the myocardial ischemic changes.

[Usefulness and limitations of three-dimensional echocardiography].

Three-dimensional echocardiography (3D) has had a great development in the last few years. Its application has expanded to all groups of heart pathology, from congenital to degenerative. In a very short time it will become an important tool in the daily work of the cardiologist. 3D represents the noninvasive macroscopic pathology anatomy equivalent.

[Non-invasive hemodynamics].

At the present time it is possible to obtain a great amount of hemodynamic information in noninvasive form, by means of the use of the diverse modalities of the Doppler/Echocardiography, in any type of cardiopathy. Some topics related to their clinical utility are analyzed.

[Echocardiographic diagnosis of obstructive intermittent dysfunction of a mitral disc prosthetic valve].

Echocardiographic findings in six patients with obstructive intermittent dysfunction of mechanical disc prosthetic mitral valve (OIPD) are described. All with a clinical picture of gradual installation and progressive dyspnea of several weeks of evolution. TTE with Bd recordings were performed in all of them with "oriented" M mode from apical 4/C view. The findings were compared with a control group of 14 patients with normal prosthetic valves. In the group of OIDP, all patients displayed a variable delay in the opening of the prosthetic disc, registered as a "protodiastolic step" in M mode. In three patients, the dysfunction was due to a thrombus. In two, due to pannus. Three were operated. One with thrombolysis. In two, the treatment consisted of heparin and increased oral anticoagulation. None die during the acute handling of the intermittent dysfunction. Two patients died: one seven months later due to cardiac failure and the other a year later due to prosthetic rethrombosis. In patients with mechanical prosthetic valve in mitral valve position and progressive dyspnea, the presence of a variable delay in the opening of the prosthesis is diagnostic of OIDP and requires urgent handling with thrombolysis or surgery.
