Introduction: Ebstein´s anomaly is a rare congenital cardiac malformation. This seen as part of a generalized disturbance in the development right ventricle and, some cases, left ventricle. Case presentation: We present two adult women with this anomaly; both mitral valve regurgitation, one them prolapse anterior leaflet and other one cleft leaflet, last have also bicuspid aortic valve, coarctation, persistence ductus arteriosus ostium secundum atrial septal defect. Conclusion: The...

Pectus excavatum (PE) and carinatum (PC) are common in Marfan syndrome (SM) similar syndromes (SS). Patients can evolve without symptoms. In some there is depression, social adjustment disorders, pulmonary cardiovascular symptoms which controversy about their relationship with the structural damage of thorax.To assess prevalence type thoracic deformity patients MS SS a historical current cohort to analyze clinical, impact.Prospective study. Subjects who met Ghent criteria had complete...

The aim of this study was to investigate the presence early left ventricular (LV) systolic dysfunction in adult patients with aortic coarctation (AoCo) and systemic arterial hypertension (SAH) compared hypertensive without healthy controls by speckle tracking.Sixty-one subjects were studied, who attended consecutively external consultation. All submitted clinical history, resting electrocardiogram, conventional echocardiogram Speckle Tracking.15 AoCo SAH functional class NYHA I, five II. A...

Background: Systemic arterial hypertension represents the mayor risk factor for several cardiovascular diseases. In a large number of patients it affects left ventricle by compensating hypertrophy and posteriorly when this mechanism is insufficient, leads to heart failure therefore patient requires regular echocardiographic monitoring. Subclinical dysfunction exists even in asymptomatic hypertensive with preserved ventricular ejection fraction. Objectives: The main aim our study was focused...

Papillary fibroelastoma is an uncommon tumor. Recognitions of this tumor have been improved thanks to modern imaging advances, which made more patients be identified, but at the same time, management disease still controversial. There aren’t enough studies basic clinical actions. We present 2 interesting cases involving semilunar valves. The purpose presenting these review rare and superiority three-dimensional echocardiography in their diagnosis.

Abstract This is a case of 37-year-old woman with uncorrected tetralogy Fallot the absence pulmonary valve and history heart murmur in childhood who did not have medical approach. At 29 years age she started dyspnoea that last 7 months progressed to be small effort also referred increase abdominal perimeter.

The aim of this study was to provide evidence abnormalities right ventricular (RV) and left (LV) function using speckle tracking echocardiography (STE) in adults with ostium secundum-atrial septal defect (OS-ASD) pulmonary hypertension (PH). Sixty-three adult patients OS-ASD were enrolled. Control group (n=10) mean arterial pressure (MPAP) ≤25 mmHg. Three PH groups divided based on artery systolic (PASP): mild (n=18), moderate (n=24) severe (n=11). RV free wall strain (RVFWS) LV global...

Abstract Background Ostium-secundum atrial septal defect (OS-ASD) increases pulmonary arterial systolic pressure (PSAP) and eventually leads to hypertension (PH). Nevertheless, whether the characteristics of OS-ASD could serve as an alleviator within chronic-volume overload in right atrium (RA) is unclear. Aims To evaluate a potential interaction diameter shunt (Qp/Qs ratio) on PSAP values patients with secondary PH. Methods We designed cross-sectional study 63 adult OS-ASD. A conventional...
