Coronary artery disease (CAD) represents a common structural cause for developing cardiac arrest in older patients, whereas in young adults cardiac arrest is more often caused by cardiomyopathies and cardiac channelopathies. A structural heart disease is known in almost 50% of patients prior to cardiac arrest. The present review outlines current interventional and operative therapeutic options for patients surviving cardiac arrest. The focus is on associations between epidemiological data on the incidence of malignant arrhythmias causing cardiac arrest depending on the presence or absence of CAD...

The Mitral Valve is a structure on the left side of the human heart that regulates the flow of oxygenated blood into the Left Ventricle and also helps maintain the pressure within the Left Ventricle when the blood gets pumped to the rest of the body from the Left Ventricle. Pathology of the Mitral Valve often manifests through structural changes in the anatomy. Assessment of Mitral Valve pathology as well as determination of specific interventions require quantification of various structures of the Mitral Valve and one of these structures of interest is the Mitral Valve annulus...

BACKGROUND: Cardiovascular diseases (CVDs) are often accompanied with comoribidities and complications leading to taking multiple drugs and thus are more liable to be exposed to drug-related problems (DRPs). DRPs can occur at any stages of medication process from prescription to follow-up treatment. However, a few studies have assessed the specific risk factors for occurrence of at least one potential DRP per patient with CVDs in sub-Saharan African region. AIM: We aim to assess the risk factors for developing potential DRPs in patients with CVDs attending Gondar University Referral Hospital (GUH)...

INTRODUCTION AND OBJECTIVES: Heart failure (HF) is associated with a high rate of readmissions within 30 days postdischarge. Strategies to lower readmission rates generally show modest results. To reduce readmission rates, we developed a STructured multidisciplinary outpatient clinic for Old and frail Postdischarge patients hospitalized for HF (STOP-HF-Clinic). METHODS: This prospective all-comers study enrolled patients discharged from internal medicine or geriatric wards after HF hospitalization...

Imaging-based evaluation of cardiac structure and function remains paramount in the diagnosis and monitoring of congenital heart disease in childhood. Accurate measurements of intra- and extracardiac hemodynamics are required to inform decision making, allowing planned timing of interventions prior to deterioration of cardiac function. Four-dimensional flow magnetic resonance imaging is a nonionizing noninvasive technology that allows accurate and reproducible delineation of blood flow at any anatomical location within the imaging volume of interest, and also permits derivation of physiological parameters such as kinetic energy and wall shear stress...

Three-dimensional (3D) printing is at the crossroads of printer and materials engineering, noninvasive diagnostic imaging, computer-aided design, and structural heart intervention. Cardiovascular applications of this technology development include the use of patient-specific 3D models for medical teaching, exploration of valve and vessel function, surgical and catheter-based procedural planning, and early work in designing and refining the latest innovations in percutaneous structural devices. In this review, we discuss the methods and materials being used for 3D printing today...

BACKGROUND: Adherence to self-care behaviors improves outcomes of patients with heart failure (HF). Caregivers play an important role in contributing to self-care. OBJECTIVE: We aimed to explore the relationships among HF knowledge, perceived control, social support, and family caregiver contribution to self-care of HF, based on the Information-Motivation-Behavioral Skills Model. METHODS: Two hundred forty-seven dyads of eligible patients with HF and family caregivers were recruited from a general hospital in China...

Ablation of ventricular tachycardia (VT) in the setting of structural heart disease, previously reserved for highly experienced specialized centers, is being performed at more centers internationally as cardiac electrophysiologists gain advanced training. Interventional cardiac electrophysiologists need a high level of anatomic knowledge to guide a procedure that can carry significant risk. Understanding cardiac anatomy improves the chance of procedural success and also the likelihood of appropriate decision making if complications are encountered...

As structural heart disease interventions continue to evolve to a sophisticated level, accurate and reliable imaging is required for pre-procedural selection of cases, intra-procedural guidance, post-procedural evaluation , as well as, for long-term follow-up of patients. Traditionally, cardiovascular procedures in the catheterization laboratory were guided by fluoroscopy and angiography. Advances in echocardiography can overcome most limitations of conventional imaging modalities and provide a successful completion of each step, of any catheter-based treatment...

Congestive heart failure (CHF) is one of the major causes of death and occurs in more than 15,000,000 patients worldwide. The incidence is expected to increase in parallel with the aging population. Most current therapies for CHF are medications, and biventricular pacing implantation as appropriated by cardiologists, or surgical interventions. The heart transplantation for indicated patients is still gold standard surgery although the 10-year survival rate is approximately 60% based on the worldwide data. However, the cardiac transplantation remains epidemiologically insignificant because of donor pool limitations...

BACKGROUND: -Although small elevations of high sensitive cardiac troponin T (hs-cTnT) are associated with incident heart failure (HF) in the general population, the underlying mechanisms are not well defined. Evaluating the association of hs-cTnT with replacement fibrosis and progression of structural heart disease prior to symptoms is fundamental to understanding the potential of this biomarker in a HF prevention strategy. METHODS: -We measured hs-cTnT at baseline among 4,986 participants in the Multi-Ethnic Study of Atherosclerosis (MESA), a cohort initially free of overt cardiovascular disease (CVD)...

BACKGROUND: Dextrocardia, or right-lying heart, is an uncommon congenital heart disease in which the apex of the heart is located on the right side of chest. Persistent left superior vena cava (PLSVA) is a rare venous anomaly that is often associated with the abnormalities of cardiac transduction system. A case with combination of dextrocardia, persistent left superior vena cava, and sick sinus syndrome has not been reported. METHODS: We used different techniques including cardiac color Doppler echocardiography, 24-hour Holter monitoring, and abdominal ultrasound to make a diagnosis and treated the patient by implanting a VVI pacemaker...

A spiral wave is a macroscopic dynamics of excitable media that plays an important role in several distinct systems, including the Belousov-Zhabotinsky reaction, seizures in the brain, and lethal arrhythmia in the heart. Because the spiral wave dynamics can exhibit a wide spectrum of behaviors, its precise quantification can be challenging. Here we present a hybrid geometric and information-theoretic approach to quantifying the spiral wave dynamics. We demonstrate the effectiveness of our approach by applying it to numerical simulations of a two-dimensional excitable medium with different numbers and spatial patterns of spiral waves...

In comparison to transthoracic echocardiography (TTE) transesophageal echocardiography (TEE) enables an acquisition of images with better spatial resolution due to the use of higher ultrasound frequencies. Thus, the morphology and function of cardiac structures can principally be analyzed better and more accurately with TEE than with TTE. In addition, using three-dimensional (3D) TEE data sets standardized sectional planes can be constructed by post-processing, which enables quantitative assessment of the target structures...

OBJECTIVE: The aim of this study was to establish if the changes in sympathetic and parasympathetic activity (analyzed through heart-rate variability [HRV]) during ultrasound (US)-guided percutaneous needle electrolysis (PNE) is due to the effect of needle puncture only or of the PNE technique per se where the puncture and galvanic current are combined. METHODS: This was an experimental, case-control study that took place at the University of Seville. Subjects were 36 male footballers who were randomly allocated to three groups: a control group (CG; 12 players), for whom HRV was recorded for 10 min, both at rest and during an exhaustive US examination of the patellar tendon and adjacent structures; a first experimental group (PNE group; 12 players), for whom HRV was recorded for 10 min, both at rest and during application of US-guided PNE in the patellar tendon; and a second experimental group (needle group; 12 players), for whom HRV was recorded for 10 min, both at rest and during application of US-guided PNE without electrical current in the patellar tendon...

Congenital heart malformations are the most common type of defects found at birth. About 1% of infants are born with one or more heart defect on a yearly basis. Congenital Heart Disease (CHD) causes more deaths in the first year of life than any other congenital abnormality, and each year, nearly twice as many children die in the United States from CHD as from all forms of childhood cancers combined. Atrioventricular septal defects (AVSD) are congenital heart malformations affecting approximately 1 in 2000 live births...

Increasing annular calcification portends more adverse outcomes and worse hemodynamic results following percutaneous structural heart interventions. Though the Direct Flow prosthesis did not appear to have significantly different post-procedural gradients based on aortic valve calcium burden in a selected group of patients, the average residual gradients were relatively high in all cases and the presence of a paravalvular leak was more common with increasing valvular calcification. It is unclear how the Direct Flow prosthesis fits into the armamentarium of TAVR prostheses...

This article describes Health for Hearts United, a longitudinal church-based intervention to reduce cardiovascular disease (CVD) risk in mid-life and older African Americans. Using community-based participatory research (CBPR) approaches and undergirded by both the Socio-ecological Theory and the Transtheoretical Model of Behavior Change, the 18-month intervention was developed in six north Florida churches, randomly assigned as treatment or comparison. The intervention was framed around three conceptual components: awareness building (individual knowledge development); clinical learning (individual and small group educational sessions); and efficacy development (recognition and sustainability)...
