Relationship Between Pulmonary Venous Flow and Prosthetic Mitral Valve Thrombosis.

Background: Prosthetic valve thrombosis (PVT) may impair pulmonary venous flow (PVF) and left atrial appendage (LAA) functions. An investigation was conducted to determine the association between left superior PVF and LAA functions and mitral PVT.

Methods: This observational case-control study included 100 consecutive patients (87 females, 13 males; mean age 59 years; range 35-71 years) with mechanical mitral PVT, and 50 age- and gender-matched otherwise healthy controls with normally functioning mitral prostheses.

Intra-aortic balloon pump experience: a single center study comparing with and without sheath insertion.

The mechanical circulation support used in treatment of low cardiac output at most is the intra-aortic balloon pump (IABP). Its usage fields are the complications occurring due to ischemic heart disease, disrupted left ventricle function, and the low cardiac output syndrome occurring during coronary artery by-pass surgery. During 28 years from 1985 to 2013, IABP support has been implemented to 3135 patients in our cardiac surgery operating theater and intensive care unit.

Is subcutaneous fat tissue embolization effective and safe as a septal reduction technique in a patient with hypertrophic obstructive cardiomyopathy?

Hypertrophic obstructive cardiomyopathy is an inheritable cardiac disease that typically manifests with an increased left ventricular outflow tract gradient. In most cases, basal septal hypertrophy and systolic anterior motion of the anterior mitral valve leaflet are the key components of the left ventricular outflow tract obstruction. The goal of septal reduction therapy, a widely accepted treatment modality, is to remove this obstruction.

Early Thrombosis of a Mitral Annuloplasty Ring in a Patient with MTHFR and Factor V Leiden Mutations.

Mitral annuloplasty ring thrombosis is an extremely infrequent pathology, for which no evidence-based antithrombotic management has yet been described. Herein is presented a case of heterozygous Factor V Leiden (FVL) and hyperhomocysteinemia with homozygous methylenetetrahydrofolate reductase (MTHFR) mutations that caused early thrombosis of the mitral annuloplasty ring. The clinical management and antithrombotic treatment of the patient, and the implications of hyperhomocysteinemia, are discussed.

Brachial embolism from mechanical mitral valve thrombosis: multimodality imaging-guided successful thrombolysis.

Saphenous vein graft aneurysm: A case report.

Background: Saphenous vein graft aneurysms (SVGAs) are rare seen issues after coronary artery bypass graft (CABG) operation which may lead to major complications including compression of adjacent structure, myocardial ischemia, rupture, and even death.

Case Report: We report a patient with recurrent SVGA and its treatment by percutaneous intervention with a covered stent, the diagnostic and treatment procedure were based on contrast enhanced computed tomography and myocardial perfusion scintigraphy (MPS).

Conclusion: Multimodality imaging is required to demonstrate the true size and complications of the SVGA, the relationship among the adjacent structure, and to assess ischemia and size of myocardial territory supplied by the aneurysmal graft to decide treatment strategy.

Rationale, design and methodology of the RAMSES Study: ReAl-life Multicenter Survey Evaluating Stroke Prevention Strategies.

Objective: Atrial fibrillation is the most common arrhythmia and is associated with a five- fold increased risk of thromboembolic events. Vitamin K antagonists (VKAs) have been the mainstay of oral anticoagulant prophylaxis and the data on stroke prevention strategies are limited to VKA era. The purpose of this study is to evaluate the use of VKA, non-Vitamin K antagonist oral anticoagulants (NOAC), and antiplatelet agents in patients with non-valvular atrial fibrillation (NVAF).

Real-time three-dimensional left ventricular contraction in patients with diastolic dysfunction.

Purpose: Systolic alterations in left ventricular (LV) myocardial function have been reported previously in patients with diastolic dysfunction (DD). Recent advances in real-time three-dimensional echocardiography (3DE) enable the measurement of a set of parameters previously difficult to obtain with standard two-dimensional echocardiography (2DE). The aim of this study was to evaluate global 3DE LV contraction in patients with and without DD who had normal ejection fraction (EF).

Predictive role of left atrial and ventricular mechanical function in postoperative atrial fibrillation: a two-dimensional speckle-tracking echocardiography study.

Objective: The aim of this study was to determine the role of left-sided mechanical parameters in postoperative atrial fibrillation (POAF) in patients undergoing coronary artery bypass grafting (CABG).

Methods: Ninety patients with coronary artery disease and normal left ventricular (LV) function in sinus rhythm were enrolled in the study. Preoperative LV and left atrial (LA) mechanics were evaluated by two-dimensional (2D) speckle-tracking echocardiography (STE), including strain and rotation parameters, and volume indices.

Intracardiac Thrombus in Behçet's Disease.

Behçet's disease (BD) is a chronic multisystem disease that presents with recurrent oral and genital ulceration and recurrent uveitis. The patients are often diagnosed in the range of 20-30 years of age and BD are more common in men.[1] BD has a worldwide distribution, but it is mainly observed in Mediterranean areas and Japan.

Multimodality imaging of a recurrent case of right-sided cardiac leiomyosarcoma with an unusual clinical course.

Primary cardiac sarcoma is an uncommon entity and is related with poor long-term survival. Presented here is an unusual case of right atrial leiomyosarcoma which almost completely occluded both the right atrium and ventricle and destroyed the tricuspid valve. Multimodality imaging was used to characterize the mass and guide surgical management.

Early Detection of Bi-ventricular and Atrial Mechanical Dysfunction Using Two-Dimensional Speckle Tracking Echocardiography in Patients with Sarcoidosis.

Purpose: Sarcoidosis is a systemic inflammatory disease with unknown etiology involving several organs. Myocardial involvement, pericarditis, severe rhythm abnormalities, and heart valve disease due to papillary muscle dysfunction are some of the cardiac manifestations. Conventional echocardiographic methods remain insufficient for the determination of subclinical myocardial dysfunction in patients with sarcoidosis.

Prediction of elevated left ventricular filling pressures in patients with preserved ejection fraction using longitudinal deformation indices of the left ventricle.

Aims: Estimation of left ventricular (LV) filling pressures is a clinical challenge in patients with preserved ejection fraction (EF). In the present study, we investigated whether LV and atrial longitudinal strain and strain rate (SR) parameters derived by speckle tracking echocardiography (STE) could be used to predict invasively measured LV end-diastolic pressure (LVEDP) in this patient population.

Methods And Results: LVEDP was measured before coronary angiography was performed in 65 patients with preserved EF (≥50%) referred to elective cardiac catheterization; besides, patients enrolled underwent comprehensive echocardiographic examination before the procedure.

[Pericardial effusion predicts mortality in patients with chronic obstructive pulmonary disease].

Objectives: Chronic obstructive pulmonary disease (COPD) is an increasingly important cause of morbidity and mortality worldwide. Pericardial effusion (PE) is a current issue proven to be a mortality predictor, especially in pulmonary arterial hypertension. In this study, we aimed to evaluate the prognostic value of PE in COPD.

Outcomes of combined cardiac surgery and kidney transplant compared with kidney transplant after cardiac surgery.

Context: Patients with chronic renal failure have a high prevalence of coronary artery disease and cardiovascular death. The mortality and the morbidity rates of cardiac surgery are particularly high in these patients with end-stage renal disease. Performing cardiac surgery and kidney transplant in the same session can reduce these complications in the early postoperative period by normalizing renal function.
