Cardiovascular diseases (CVD) represent an important cause of mortality and morbidity in women. It is now recognized that there are sex differences regarding the prevalence and the clinical significance of the traditional cardiovascular (CV) risk factors as well as the pathology underlying a range of CVDs. Unfortunately, women have been under-represented in most CVD imaging studies and trials regarding diagnosis, prognosis, and therapeutics.

Study Objectives: Obstructive sleep apnea (OSA) is associated with cardiovascular comorbidities such as left ventricular (LV) hypertrophy. Whether OSA is an independent etiological factor for this hypertrophic remodeling is yet unknown. Continuous positive airway pressure partially reverses this hypertrophy, but data regarding the effect of mandibular advancement devices on LV remodeling are scarce.

Background: Tricuspid regurgitation (TR) has been associated with cardiac rhythm device (CRD) implantation with intracardiac lead insertion. However, data on the incidence of postdevice TR are limited and largely from retrospective studies. We hypothesized that permanent lead implantation would be associated with an increase in TR.

Aims: In addition to increased risk of cardiovascular disease, the prevalence of diabetic cardiomyopathy is increasingly recognized in patients with type 1 diabetes mellitus (T1DM). We aimed to identify the occurrence of subclinical markers of cardiovascular risk and cardiac dysfunction and assess their relation to clinical parameters in asymptomatic patients with T1DM.

Methods And Results: A total of 102 patients (mean age 46 years [20-73], 62% male) with a history of T1DM ranging from 5 to 47 years underwent standard 2D and pulse-wave tissue Doppler echocardiography (Philips iE33) and computerized tomography for assessment of coronary calcium score (CACS) and visceral fat.

Background: Increase of exercise capacity (peak VO) after cardiac rehabilitation improves outcome in patients with coronary artery disease (CAD). Systolic and diastolic function have been associated with peak VO, but their role towards improvement of exercise capacity remains unclear. It is unknown which exercise intensity has the most beneficial impact on left ventricular (LV) geometry and function in CAD patients without heart failure.

Given the increasing numbers of cardiac device implantations worldwide, it is important to determine whether permanent endocardial leads across the tricuspid valve can promote tricuspid regurgitation (TR). Virtually all current data is retrospective, and indicates a signal of TR being increased after permanent lead implantation. However, the precise incidence of moderate or greater TR post-procedure, the exact mechanisms (mechanical, traumatic, functional), and the hemodynamic burden and clinical effects of this putative increase in TR, remain uncertain.

Unlabelled: In the last decade, cardiac computed tomography (CT) has gained mainstream acceptance for the noninvasive exclusion of significant coronary disease in a selected population. Improvements in electrocardiogram (ECG)-triggered imaging techniques also allow, by extension, a proper evaluation of the complete heart anatomy. Given the increasing worldwide clinical implementation of cardiac CT for coronary artery evaluation, radiologists can, incidentally, be confronted with unfamiliar and previously unsuspected non-coronary cardiac pathologies, including congenital morphological defects.

Background: Exercise-based cardiac rehabilitation increases peak oxygen uptake (peak VO₂), which is an important predictor of mortality in cardiac patients. However, it remains unclear which exercise characteristics are most effective for improving peak VO₂ in coronary artery disease (CAD) patients. Proof of concept papers comparing Aerobic Interval Training (AIT) and Moderate Continuous Training (MCT) were conducted in small sample sizes and findings were inconsistent and heterogeneous.

Transcatheter aortic valve replacement represents one of the most exciting medical technical developments in recent years, offering a much-needed therapeutic alternative for patients with severe aortic valve stenosis who, due to comorbidities and advanced age, are considered to be inoperable or at high surgical risk. The efficacy of this procedure compared with standard surgical intervention has been properly validated in multicenter randomized controlled trials (PARTNER A and B trials), leading to widespread clinical implementation, with over 50,000 procedures currently being performed worldwide each year. Although much of the attention has rightly focused on the potential role of computed tomography (CT) in the preprocedural assessment of the aortic root and the establishment of imaging-guided valve-sizing algorithms, less is known regarding the postprocedural CT characteristics of transcatheter heart valves (THVs).

Aortic valve stenosis is the most common valvular heart disease in the Western world. When symptomatic, aortic valve stenosis is a debilitating disease with a dismal short-term prognosis, invariably leading to heart failure and death. Elective surgical valve replacement has traditionally been considered the standard of care for symptomatic aortic valve stenosis.

Objectives: The purpose of this study was to compare sulfur hexafluoride microbubble (SonoVue)-enhanced myocardial contrast echocardiography (MCE) with single-photon emission computed tomography (SPECT) relative to coronary angiography (CA) for assessment of coronary artery disease (CAD).

Background: Small-scale studies have shown that myocardial perfusion assessed by SonoVue-enhanced MCE is a viable alternative to SPECT for CAD assessment. However, large multicenter studies are lacking.

Background: Exercise-based cardiac rehabilitation is considered an important adjunct treatment and secondary prevention measure in patients with coronary artery disease (CAD). However, the issues of training modality and exercise intensity for CAD patients remain controversial.

Objective: Main aim of the present study is to test the hypothesis that aerobic interval training (AIT) yields a larger gain in peak aerobic capacity (peakVO2) compared to a similar training programme of moderate continuous training (MCT) in CAD patients.

We report an atypical echocardiographic presentation of Staphylococcus aureus infective endocarditis (IE) of the mitral valve in an octogenarian female. Echocardiography revealed perforation of the anterior mitral valve leaflet (AMVL), with a large cystic mass seemingly attached to the AMVL and surrounded by a thin membranous structure. These images were strongly reminiscent of a hydatid cyst.

The finding of a cardiac myxoma usually implies immediate consequent surgical excision to prevent embolic events. Reports with documented growth rate are therefore very rare, and the actual growth rate remains a controversial issue. We report the growth of a left atrial myxoma in an asymptomatic 65-year-old patient with several years of follow up for aortic valve disease.

Left atrial wall calcifications are an extremely rare finding of unknown cause usually associated with rheumatic disease. Only a few case reports of this entity are found in the literature, mostly describing the findings on conventional chest radiography, echocardiography, and angiography. To the best of our knowledge, this is the first case documented with multislice computed tomography.

In this report, we describe a patient with two uncommon cardiac abnormalities: a subvalvular membrane in the left ventricular outflow tract and a cardiac fibroma (CF) in the left atrium. This 56-year-old patient presented with a known subaortic stenosis caused by a subvalvular membrane, a large mass attached to the interatrial septum in the immediate proximity of mitral valve, and a cardiac history of infective endocarditis. Initially, the mass was thought to be an old vegetation.
