To evaluate, by transthoracic echocardiography dimensions and function of right chambers, according to gender, body surface area and body mass index in an outpatient population.

Method

Cross-sectional study. Eighty-one patients were selected, 60.4 ± 13.5 years (57 women, 70%). Parameters assessed were the following: proximal, basal, medium and longitudinal, right ventricle diameter; right atrium area and right atrium volume; right ventricle wall thickness; tricuspid annular plane systolic excursion; and tricuspid annulus tissue Doppler and S’ wave. Results: Female sex presented lower diameters (Student’s t-test) of proximal right ventricle diameter (20.6 mm ± 2.4 vs. 22.7 mm ± 2.2; p = 0.001), basal right ventricle diameter (34,4 mm ± 3,5 vs. 38,2 mm ± 4,8; p < 0.001), medium right ventricle diameter (27 mm ± 3.3 vs. 32.4 mm ± 4.9; p < 0.001), right atrium area (13.7 cm² ± 2.7 vs. 16.6 cm² ± 3.9; p = 0.002) and right atrium volume (37 mL ± 10.6 vs. 50.7 mL ± 15.6 ; p = 0.002). Body mass index and body surface area correlated with proximal right ventricle diameter (correlation coefficient – CC 0.24; p = 0.03), basal right ventricle diameter (CC 0.22; p = 0.04), medium right ventricle diameter (CC 0.23; p = 0.04), longitudinal right ventricle diameter (CC 0.28; p = 0.01), right atrium area (CC 0.40; p = 0.001), and right atrium volume (CC 0.24; p = 0.0006).

Conclusion

Right ventricular diameters, right atrial area and volume were lower in females. A correlation was found with body mass index and body surface area. Tricuspid annular plane systolic excursion and S’ were not influenced by sex, body mass index and body surface area.

A Three-Leaflets Mitral Valve Associated to Three Papillary Muscles in a Patient with Hypertrophic Cardiomyopathy

Antonio Tito Paladino et al. Luiz Antônio Vasconcelos Leonardo Mello Guimarães de Toledo Natalia Massoni … Mariana Oliveira Rezende Natasha Soares Simões dos Santos David Costa de Souza Le Bihan Rodrigo Bellio de Mattos Barretto Jorge Eduardo Assef

Abstract

Mitral valve malformations are considered rare even in their association with other anomalies, except for mitral valve prolapse, which is found in approximately 10% of the population. Mitral valve abnormalities may affect any portion of the valve or subvalvular apparatus (annulus, cusp, tendinous cords or papillary muscles).^1,2 Mitral valve anatomy and function can be assessed by echocardiography, resonance or cardiac tomography, and is essential for potential therapeutic programming.²

Longitudinal Strain and Cardiac Amyloidosis: Case Reports

Ana Luiza Alves Nicoletti et al. Amanda Cristina de Souza Valter Kuymjian Jaqueline Kuymjian … Daniel F. Palmieri Fabio F. Giuseppin Danilo G. Fernandes Simone N. Santos

Abstract

Introduction

Cardiac involvement in patients with systemic amyloidosis indicates a worse prognosis. Moreover, the diagnosis is delayed, since the signs and symptoms of this disease are nonspecific. Global longitudinal strain has been shown to be an important predictor of cardiac events. We report four cases of patients with cardiac amyloidosis submitted to ECHO Strain and magnetic resonance for comparison and diagnostic confirmation.

Case reports

The medical records of four patients with cardiac amyloidosis admitted in 2017 at a tertiary hospital were evaluated. The preservation of the apical segments of the ventricle was the pattern found in all global longitudinal strain. Magnetic resonance image showed predominantly subendocardial, diffuse and circumferential mesocardial late enhancement in all patients reported.

Discussion

On the spectrum of clinical manifestations of cardiac amyloidosis, heart failure was the most prevalent among the patients reported. Magnetic resonance image showed patterns of myocardial thickening and late subendocardial enhancement. In global longitudinal strain, we observed the preservation of the deformity in the apical segments, associated with a significant reduction of the deformity in the basal and middle segments of the left ventricle. The global longitudinal strain also allows differential diagnosis with hypertrophic cardiomyopathy and its findings were consistent with those of the magnetic resonance image, which reinforces its value in the early detection of the condition.

Inferolateral post-myocardial infarction pseudoaneurysm. A rare case report

Gabriel De Castro Vaz Leal et al. Renato de de Aguiar Hortegal Antonio Tito Paladino Filho Diandro Marinho Mota … Rodrigo Barreto de Bellio Mattos Louis Nakayama Ohe

Abstract

We report the case of a 76-year-old male patient with a history of ST-segment elevation myocardial infarction (STEMI) for 3 years. He was admitted to the Emergency Room with a new chest pain episode that began 40 days before and was diagnosed with left ventricular (LV) pseudoaneurysm through 3D transthoracic echocardiography and cardiac magnetic resonance imaging scans. The patient underwent angiography of the coronary arteries, identifying lesions with a multiarterial pattern. Surgical treatment and LV aneurysmectomy were performed with good clinical evolution.
