Assessment of flow pattern of right ventricle outflow and pulmonary arteries in surgically corrected tetralogy of Fallot patients by four-dimensional cardiac magnetic resonance flow.

Background: The most common post-surgical complication of tetralogy of Fallot (TOF) is pulmonary regurgitation (PR) which can lead to right ventricle (RV) dysfunction/failure. Cardiac magnetic resonance (CMR) is the imaging modality of choice to follow-up a repaired TOF. However, the conventional two-dimensional phase-contrast (2D-PC) flow usually underestimates PR as well as the pulmonary peak systolic velocity (PSV).

Presentation, management, and outcomes of STEMI in Egypt: results from the European Society of Cardiology Registry on ST elevation myocardial infarction.

Background: Apart from few small single-center studies, there are limited data about STEMI patients in Egypt. Nineteen Egyptian centers (with and without PCI facilities) participated in this registry with 1356 patients who were compared to 7420 patients from other ESC countries. The aims of this study were to describe the characteristics of patients with STEMI, to assess STEMI management patterns particularly the current use of reperfusion therapies, to evaluate the organization of STEMI networks across Egypt, to evaluate in-hospital patient outcome, and to compare Egyptian patients with other ESC countries.

Serum soluble Fas in patients with Schistosomal cor pulmonale.

Background: Schistosomal cor pulmonale is considered an important pathological condition in endemic areas. Few recent studies have reported the role of apoptosis in pulmonary hypertension.

Objectives: The aim of this study was to assess serum levels of soluble Fas (sFas), an inhibitor of apoptosis, in patients with schistosomal cor pulmonale as compared to patients with cor pulmonale due to chronic obstructive pulmonary disease (COPD) and normal subjects.

Assessment of left internal mammary artery graft patency by transthoracic Doppler echocardiography.

Background: The successful application of noninvasive Doppler spectrum analysis has been reported for the hemodynamic assessment of LIMA graft after myocardial revascularization.

Hypothesis: The objective of this study was to assess the utility of transthoracic Doppler echocardiography (TTE) in providing information on LIMA flow in patients after coronary artery bypass graft surgery.

Methods: In all, 22 patients (aged 62 +/- 8 years) with LIMA graft to the left anterior descending (LAD) coronary artery who underwent coronary angiography were assessed using high-frequency (5 MHz) transthoracic Doppler echocardiography.
