An Echocardiographic Study of a Rare Cause of Mitral Regurgitation: Hypoplastic Posterior Mitral Valve Leaflet.

Background: The precise etiology of hypoplasia of the posterior mitral valve leaflet (PMVL) remains incompletely elucidated; however, it has been hypothesized to stem from genetic mutations occurring during fetal development. Herein, we present the anatomical characteristics of the mitral valve and associated cardiac pathologies in patients with hypoplastic PMVL.

Methods: This single-center retrospective study involved patients who presented between 2015 and 2021 at a tertiary healthcare facility.

Multimodality Imaging in Cardiomyopathies.

Cardiomyopathy, which is shortly defined as a disease of the myocardium, has a broad definition that includes many different diagnoses. Recent advances in cardiac imaging techniques, including basic and advanced echocardiography, computed tomography, nuclear medicine, and cardiac magnetic resonance, allow for a more accurate evaluation of volumes and thickness of cardiac chambers, systolic and diastolic function of the ventricules, and tissue structure. Multimodality imaging often provides the first clinical suspicion for specific etiologies, especially when the medical and family history is unclear, by identification of red flags of underlying systemic diseases.

Let's put the clues together and find the aetiology in this patient with dilated right heart!

A 39-year-old woman with intermittent palpitations, psoriasis, and a family history of sudden death presented with dilated right heart chambers and an enlarged coronary sinus. Despite a normal bubble study, further evaluation with transesophageal echocardiography revealed an abnormal pulmonary venous return: the left pulmonary veins drained into the coronary sinus. Cardiac computed tomography confirmed this finding, suggesting a partial abnormal pulmonary venous return as the underlying issue.

Inflammation Burden and Atrial Fibrillation Burden: A Bidirectional Relationship.

Background: Atrial fibrillation (AF) burden is defined as the proportion of time the patient remains in AF over a given period of time; thus, it is theoretically highest in permanent AF and lowest in paroxysmal AF. Inflammation is associated with the initiation and maintenance of AF. However, the relationship between systemic immune-inflammation index (SII) and AF burden is unknown.

Multimodality Imaging of Intimal Sarcoma Causing Both Severe Mitral Stenosis and Mitral Regurgitation.

Intimal sarcomas (IS) are rare, malignant, rapidly progressive mesenchymal tumors that typically occur in the tunica intima of larger vessels, and they rarely involve the heart. IS are frequently misdiagnosed during the initial clinical presentation. This case report describes an uncommonly located IS, highlighting specific findings obtained through multimodality imaging.

Combination anticoagulation strategy in pregnancy with mechanical valves: The KYBELE study.

Background: Optimal first-trimester anticoagulation is still challenging in pregnant women with mechanical heart valves (MHVs) requiring high-dose warfarin. This multicenter prospective study aims to determine the optimal anticoagulation regimens for pregnant patients with MHVs.

Methods: All women were allocated to one of three treatment options during first trimester including lone low-molecular-weight heparin (LMWH), combination of LMWH + 2.

Transcatheter Closure or Surgery for Symptomatic Paravalvular Leaks: The Multicenter KISS Registry.

Background: The optimal treatment of symptomatic paravalvular leak (PVL) remains controversial between transcatheter closure (TC) and surgery. This large-scale study aimed to retrospectively evaluate the long-term outcomes of the patients who underwent reoperation or TC of PVLs.

Methods And Results: A total of 335 (men, 209 [62.

Transcatheter mitral paravalvular closure: a single centre experience with techniques and outcomes.

Background: In patients with symptomatic mitral PVL, successful transcatheter reduction of the PVL to less than mild is associated with significant improvement in short- and midterm survival.

Objectives: In this study, we present our single-centre, same operators' experience on percutaneous paravalvular leak closure with techniques and outcomes.

Methods: In this retrospective observational designed study, we retrieved hospital records of patients with a surgical history of mechanical or biological prosthetic valve replacement and who subsequently underwent transcatheter mitral paravalvular leak closure (TMPLC).

3D TEE imaging in a patient with severe tricuspid regurgitation with dextrocardia and tricuspid commissural prolapse.

Although dextrocardia is a rare congenital anomaly, it may be accompanied by numerous pathologies. Tricuspid valve prolapse is an extremely uncommon cause of primary tricuspid valve disease, as is its association with dextrocardia. In this instance, we wished to share our knowledge of tricuspid commissural prolapse together with dextrocardia, which we augmented with 3D images.

Impact of Naples Prognostic Score on midterm all-cause mortality in patients with decompensated heart failure.

This work was designed to investigate the relationship between cardiac outcomes and Naples Prognostic Score (NPS) among heart failure (HF) patients. This retrospective observational study enrolled 298 consecutive individuals hospitalized for New York Heart Association class 3-4 HF. The primary outcome was all-cause mortality.

Does papillary muscle free strain has predictive value in risk stratification of patients with hypertrophic cardiomyopathy?

Background: Papillary muscle free strain has not been evaluated previously in hypertrophic cardiomyopathy (HCMP) patients. Our aim was to evaluate free papillary muscle free strain in HCMP patients and to find whether it has a value for prediction of sudden cardiac death (SCD) risk score.

Methods: Transthoracic echocardiography with tissue Doppler imaging, 2-D speckle tracking imaging (STI) of 55 HCMP patients and 45 controls were performed.

Gender-Dependent Comparison of Coronary Computed Tomography Angiographic Characteristics among Patients with Suspected Atherosclerosis: A Single-Center Experience.

Objective: In this study, we aimed to examine gender-based differences in coronary artery disease (CAD) risk factors, the presence and severity of atherosclerosis, and the distribution of plaque type in patients presenting with chest pain.

Methods: A total of 1496 patients who applied to our cardiology outpatient clinic with chest pain and underwent computed coronary tomographic angiography (CTA) between August 2020 and October 2021 were included in the study. Plaque characteristics, Agatston score, and Coronary Artery Disease-Reporting and Data System (CAD-RADS) score obtained from the patients' CTAs were compared by gender.

A rare cause of pulmonary hypertension: Idiopathic fibrosing mediastinitis obstructing right pulmonary artery and pulmonary veins.

Fibrosing mediastinitis is caused by a proliferation of fibrous tissue in the mediastinum with encasement of mediastinal viscera and compression of mediastinal bronchovascular structures. Pulmonary hypertension (PH) may occur as a severe complication of the disease. Herein, we report a patient diagnosed with fibrosing mediastinitis and pulmonary hypertension, whose imaging tests showed obstruction of right pulmonary artery and veins.

Double trouble during the left atrial appendage occlusion procedure.

Percutaneous structural interventions are being performed at increased numbers and rare findings or complications occur more frequently. Lipomatous hypertrophy of the interatrial septum (LHIS) is a relatively uncommon finding on transthoracic echocardiogram (TTE). The major challenge is the difficulty in performing transseptal puncture.

The factors associated with progression of tricuspid regurgitation after left-sided double valve replacement in propensity score matched analysis.

Background: This study aims to investigate the association of progression of tricuspid regurgitation following double-valve replacement by comparing the tricuspid valve repair and no repair groups, and to analyze outcomes of patients with non-repaired mild-to-moderate tricuspid regurgitation.

Methods: Between January 2014 and September 2017, a total of 157 patients (74 males, 83 females; mean age: 51.7±13.

A combination of severe complications in a case of infective endocarditis: Dehiscence of prosthetic aortic valve, aortic dissection, pseudoaneurysm, and hematoma causing right ventricular collapse.

Prosthetic valve endocarditis with mechanical complications causing pulmonary edema is fatal, therefore it needs to be diagnosed early and should be treated surgically in emergency setting. Transesophageal echocardiogram is crucial for recognizing the mechanical complications, which can be encountered on daily practice, but the coexistence of complications occurring on different mechanism is rather uncommon. Herein, we report a 21-year-old gentleman presenting with acute heart failure, whose imaging tests showed a combination of dehiscence of mechanical aortic valve prosthesis, aortic dissection, pseudoaneurysm, and hematoma causing right ventricular collapse.

Diagnosis of Pulmonary Artery Sarcoma with Multi-modality Imaging.

Pulmonary artery sarcoma is an extremely uncommon malignancy with a poor prognosis. It is often difficult to distinguish it from pulmonary thromboembolic disease because of nonspe cific signs and symptoms as well as similar imaging findings. We present a 46-year-old man who had initially been diagnosed with presumed asthma that later proved to be pulmonary artery sarcoma.

Serum Levels of Cholesterol and Lipoproteins in Patients With Symptomatic Paravalvular Leaks.

Paravalvular leak (PVL) is a complication of valve replacement surgery which may lead to serious clinical consequences including hemolytic anemia. This study aimed to retrospectively evaluate the effect of successful intervention on serum lipid parameters in patients with PVL. A total of 106 patients (mean age: 57.
