BACKGROUND AND AIMS: The main stages of cirrhosis (compensated and decompensated) have been substaged based on clinical, endoscopic, and portal pressure (determined by the hepatic venous pressure gradient, HVPG) features. Vasodilatation leading to a hyperdynamic circulatory state is central in the development of a late decompensated stage with inflammation being currently considered a key driver. We aimed to assess hepatic/systemic hemodynamics and inflammation (by C reactive protein, CRP) among the different substages of cirrhosis and to investigate their interrelationship and prognostic relevance...

BACKGROUND AND OBJECTIVE: In interstitial lung disease (ILD), pulmonary hypertension (PH) is a major adverse prognostic determinant. Transthoracic echocardiography (TTE) is the most widely used tool when screening for PH, although discordance between TTE and right heart catheter (RHC) measured pulmonary haemodynamics is increasingly recognized. We evaluated the predictive utility of the updated European Society of Cardiology/European Respiratory Society (ESC/ERS) TTE screening recommendations against RHC testing in a large, well-characterized ILD cohort...

Catheter-based interventions in the early post-operative period are performed with caution due to concerns for increased procedural risk, particularly across fresh suture lines. The recently published CRISP scoring system provides prospective risk stratification based on pre-procedural criterion. In an effort to refine the assessment of risk in patients undergoing post-operative catheter-based interventions, the predicted risk of an adverse event based on CRISP scores was compared to actual adverse event rates...

BACKGROUND: Cerebral oximetry using near-infrared spectroscopy is a noninvasive optical technology to detect cerebral hypoxia-ischemia and develop interventions to prevent and ameliorate hypoxic brain injury. Cerebral oximeters are calibrated and validated by comparison of the near-infrared spectroscopy-measured cerebral O2 saturation (SctO2) to a "field" or reference O2 saturation (REF CX) calculated as a weighted average from arterial and jugular bulb oxygen saturations. In this study, we calibrated and validated the second-generation, 5 wavelength, FORE-SIGHT Elite with the medium sensor (source-detector separation 12 and 40 mm) for measurement of SctO2 in children with congenital heart disease...

A patient with a history of lung adenocarcinoma was admitted because of palpitation. Transthoracic echocardiogram revealed a mass (74×42 mm) in the right ventricle. Computed tomography showed a tumor lesion in the right ventricular cavity but no other distant metastasis. Coronary angiography revealed well-developed small branches to the tumor. After right heart catheterization, a pathological analysis of a tumor biopsy demonstrated adenocarcinoma. We diagnosed the patient with right ventricular metastasis of lung cancer...

Advances in medical diagnosis reveal that coronary artery aneurysms (CAAs) may develop in several clinical scenarios and manifest variable symptoms, imaging appearances, and outcomes. Aneurysms are pathologically classified into three groups: atherosclerotic, inflammatory, and noninflammatory. The last category is associated with congenital, inherited, and connective tissue disorders. Overlap exists among the groups, because secondary atherosclerotic change may be present in an aneurysm of any cause. Atherosclerosis is the most common cause of CAAs in adults, and inflammation is considered the underlying mechanism...

BACKGROUND: The treatment of choice for chronic thromboembolic pulmonary hypertension (CTEPH) is pulmonary endarterectomy (PEA). However, not all patients are eligible for PEA, and some patients experience recurrence of pulmonary hypertension even after PEA. METHODS: Patients who underwent balloon pulmonary angioplasty (BPA) between December 2015 and April 2017 were enrolled from the Samsung Medical Center CTEPH registry. Enrolled patients underwent right heart catheterization, echocardiography, and 6-minute walk distance (6MWD) at baseline, 4 and 24 weeks after their first BPA session...

Arka Chatterjee, William B Hillegass
Patient preference should emerge as a third component influencing radial versus femoral access for cardiac catheterization. Ideally dually experienced "switch-operators" will consider co-morbidities, technical procedural factors, and patient preferences to choose a tailored approach with each patient. A tailored and tempered three component approach to access selection which includes patient preferences will likely optimize patient-centered outcomes.

Robotic percutaneous coronary interventions have recently been introduced in the cardiac catheterization laboratory. Robotics offers benefits of greater precision for stent placement and occupational hazard protection for operators and staff. First generation systems were able to advance and retract coronary wires, balloons, and stents, but did not have guide control functions. The second-generation robotic system (CorPath GRX) has an active guide management function offering the ability to move guide catheters...

BACKGROUND: Early-diastolic mitral annular velocity (e') and the ratio of early-diastolic left ventricular (LV) inflow velocity (E) to e' (E/e') have been widely used as indexes of LV relaxation and filling pressure, respectively. However, many recent studies have demonstrated that they are not reliable in various clinical settings. We thus investigated the factors influencing these echocardiographic parameters in a multicenter study.Methods and Results:The study group comprised 69 patients, referred for cardiac catheterization, and enrolled in 5 university hospitals...

Background - Poor fitness in middle age is a risk factor for heart failure, particularly heart failure with a preserved ejection fraction. The development of heart failure with a preserved ejection fraction is likely mediated through increased left ventricular (LV) stiffness, a consequence of sedentary aging. In a prospective, parallel group, randomized controlled trial, we examined the effect of 2 years of supervised highintensity exercise training on LV stiffness. Methods - Sixty-one (48% male) healthy, sedentary, middle-aged participants (53±5 years) were randomly assigned to either 2 years of exercise training (n=34) or attention control (control; n=27)...

BACKGROUND: At our institution, we perform bilateral pulmonary artery banding (BPAB) as the first-stage palliation for interrupted aortic arch (IAA) with low birth weight or severe subaortic stenosis (SAS). The present study aimed to identify factors that may influence the decision regarding the type of second-stage operation, that is, univentricular palliation or biventricular repair, in these patients. METHODS: Cardiac catheterization and angiographic data of nine patients with IAA who underwent initial BPAB and subsequent univentricular or biventricular repair were retrospectively analyzed...

RATIONAL: Takotsubo cardiomyopathy (TCM) is a transient systolic dysfunction of the left ventricular apex without stenosis of coronary arteries and is induced by various psychological and physical factors. TCM sometimes causes lethal complications such as arrhythmia, thrombogenesis, and even cardiac rupture, and thus it should be diagnosed appropriately and managed carefully. Intensive care unit (ICU) patients are exposed to overstress during the treatment process and therefore can are at potential risk for TCM...

Caseous calcification of the mitral annulus (CCMA) is a rare echocardiographic finding. It is commonly misdiagnosed as an abscess, tumor or infective vegetation on the mitral valve. Since it is a benign process, differentiating it from malignant intra-cardiac mass is primordial to avoid unnecessary surgery. Various imaging modalities can be complimentary for definitive diagnosis. We present a case of CCMA in a 71-year-old female patient. Her medical history revealed hypertension, diabetes mellitus, hyperlipidaemia and coronary artery disease...

It is not uncommon to see in developing and underdeveloped countries, where the anesthesiologist who is untrained in cardiac specialty takes care of cardiac catheterization centers. The service in cardiac catheterization laboratories (CCL) in developed countries and some of the developing countries is mainly provided by the cardiac anesthesiologists. The scenario is not same in some part of developing countries or in underdeveloped countries which are mainly due to increase in number of CCL (catheterization laboratory) when compared to the number of cardiac anesthesiologists working outside the operation theater...

BACKGROUND: It is widely recognized that overt hyper- as well as hypothyroidism are potential causes of heart failure (HF). Additionally it has been recently reported that subclinical hypothyroidism (sub-hypo) is associated with atherosclerosis, development of HF, and cardiovascular death. We aimed to clarify the effect of sub-hypo on prognosis of HF, and underlying hemodynamics and exercise capacity. METHODS: We measured the serum levels of thyroid stimulating hormone (TSH) and free thyroxine (FT4) in 1100 consecutive HF patients...
