Univentricular hearts not undergoing Fontan: the type of palliation matters.

Introduction And Objectives: There is scarce information on patients with single ventricle physiology (SVP) and restricted pulmonary flow not undergoing Fontan circulation. This study aimed to compare survival and cardiovascular events in these patients according to the type of palliation.

Methods: SVP patient data were obtained from the databases of the adult congenital heart disease units of 7 centers.

A new score for life-threatening ventricular arrhythmias and sudden cardiac death in adults with transposition of the great arteries and a systemic right ventricle.

Aims: To investigate the incidence of major adverse ventricular arrhythmias and related events (MAREs) and to develop a stratification tool predicting MAREs in adults with a systemic right ventricle (sRV).

Methods And Results: In a multicentre approach, all adults (≥16 years old) with a sRV undergoing follow-up between 2000 and 2018 were identified. The incidence of MAREs, defined as sudden cardiac death, sustained ventricular tachycardia, and appropriate implantable cardioverter-defibrillator (ICD) therapy, was analysed.

Determinants of oxygen uptake and prognostic factors in cardiopulmonary exercise test in patients with Fontan surgery.

Introduction: Cardiopulmonary exercise test (CPET) allows quantification of functional capacity of patients with Fontan.

Hepatopulmonary syndrome: which blood gas analysis criteria and position should we use for diagnosis?

Introduction: Different blood gas criteria have been used in the diagnosis of hepatopulmonary syndrome (HPS).

Patients And Methods: Arterial blood gases were prospectively evaluated in 194 cirrhotic candidates for liver transplantation (LT) in the supine and seated position. Three blood gas criteria were analyzed: classic (partial pressure of oxygen [PaO2] < 70 mmHg and/or alveolar-arterial gradient of oxygen [A-a PO2] ≥ 20 mmHg), modern (A-a PO2 ≥ 15 mmHg or ≥ 20 mmHg in patients over 64) and the A-a PO2 ≥ threshold value adjusted for age.

Natural History and Clinical Predictors of Atrial Tachycardia in Adults With Congenital Heart Disease.

Background: Atrial tachycardias (ATs) are a significant source of morbidity in adults with congenital heart disease (CHD). This study evaluates the incidence and clinical predictors of AT in a cohort of patients with CHD.

Methods And Results: We included 3311 adults (median age at entry 22.

The utility of the macro-aggregated albumin lung perfusion scan in the diagnosis and prognosis of hepatopulmonary syndrome in cirrhotic patients candidates for liver transplantation.

Background: The macro-aggregated albumin lung perfusion scan (99mTc-MAA) is a diagnostic method for hepatopulmonary syndrome (HPS).

Goal: To determine the sensitivity of 99mTc-MAA in diagnosing HPS, to establish the utility of 99mTc-MAA in determining the influence of HPS on hypoxemia in patients with concomitant pulmonary disease and to determine the correlation between 99mTc-MAA values and other respiratory parameters.

Methods: Data from 115 cirrhotic patients who were eligible for liver transplantation (LT) were prospectively analyzed.

Impaired right and left ventricular mechanics in adults with pulmonary hypertension and congenital shunts.

Aims: To assess left ventricle mechanics in Eisenmenger physiology patients with congenital shunts, and their relationship with the right ventricle, and to consider the clinical usefulness of this information.

Methods: The study involved 28 patients with pulmonary artery hypertension (PAH) and congenital shunt, matched with 28 healthy participants. Standard echocardiography and pulsed wave tissue Doppler imaging were employed to analyze systolic and diastolic ventricular function, the myocardial performance index (MPI) of ventricles, and the strain and strain rate along the left ventricle lateral wall, septum, and right ventricle free wall.

Mid-term morbidity and mortality of patients after arterial switch operation in infancy for transposition of the great arteries.

Introduction And Objectives: The arterial switch operation is currently the preferred surgical approach for complete transposition of the great arteries. We sought to determine the mid-term results of this intervention.

Methods: A single-institution retrospective review of clinical records of all consecutive patients who underwent the arterial switch surgery between 1985 and 2010.

Prognostic value of different serum biomarkers for left ventricular remodelling after ST-elevation myocardial infarction treated with primary percutaneous coronary intervention.

Background: Mortality derived from ST-elevation myocardial infarction (STEMI) has decreased due to primary percutaneous coronary intervention (PCI). Paradoxically, the incidence of heart failure secondary to left ventricular remodelling (LVR) is on the rise due to the survival derived from reperfusion strategies. The aim of this study was to assess the prognostic value for LVR of biomarkers involved in several pathophysiological mechanisms activated during STEMI treated with primary PCI.

Right atrium mass in a 28-year-old patient with pulmonary embolism taking contraceptives.

We report the case of a 28-year-old woman taking contraceptives diagnosed with pulmonary embolism with a mass in the right atrium demonstrated by trans-thoracic echocardiogram that was not recognized on a previous angio-CT. Initially, it was thought to be a thrombus, but trans-oesophageal echocardiography and cardiac MRI showed data suggestive of cardiac neoplasm. Pericardial effusion and adjacent myocardial wall thickening noted on trans-oesophageal echocardiography were reported as signs that supported the possibility of malignancy, although cardiac MRI did not show wall infiltration signs.

Value of NT-ProBNP level and echocardiographic parameters in ST-segment elevation myocardial infarction treated by primary angioplasty: relationships between these variables and their usefulness as predictors of ventricular remodeling.

Introduction And Objectives: To assess the value of N-terminal fragment of brain natriuretic peptide (NT-proBNP) measurement and echocardiography for predicting ventricular remodeling after myocardial infarction and to investigate relationships between the NT-proBNP level and echocardiographic parameters at discharge and in the medium term.

Methods: The study involved 159 patients with myocardial infarction treated by primary coronary angioplasty. The NT-proBNP level was measured on admission, at discharge and after 6 months.

Patent foramen ovale not so patent.

Transesophageal echocardiography (TEE) with agitated saline contrast is the most sensitive tool for diagnosing patent foramen ovale (PFO), but false positives can result. We report a patient who underwent a TEE during the study of a cryptogenic stroke. Contrast appeared in the left atrium with the Valsalva maneuver.

A heart inside the heart: blood cyst of mitral valve.

We report a case of giant blood cyst originating from the anterior mitral valve leaflet, which was discovered during a two-dimensional echocardiography examination performed for investigation of a systolic murmur in a 34-year-old healthy man. Three-dimensional microbubble-enhanced images showed a heart-shape appearance that may be pathognomonic for blood cyst of the mitral valve.

Glucose effectiveness is strongly related to left ventricular mass in subjects with stage I hypertension or high-normal blood pressure.

Background: Evidence suggests that "glucose effectiveness," (SG) or the effect of glucose per se to enhance net glucose disposal, may be at least as important as the insulin sensitivity index (SI) in the assessment of glucose tolerance. Our objective was to study the relationship of SG and SI parameters to left ventricular mass in a group of untreated, nondiabetic, and nonobese subjects recently diagnosed with stage I or high-normal blood pressure (BP).

Methods: In this sample of subjects, among whom the expected prevalence of insulin resistance is low, we assessed SG and SI parameters using the intravenous glucose tolerance test and minimal model analysis.
