This study aims to review pediatric pulmonary hypertension (PH) by comparing the guidelines of the European Society of Cardiology (ESC)/European Respiratory Society (ERS), the American Heart Association (AHA)/American Thoracic Society (ATS), and the European Pediatric Pulmonary Vascular Disease Network (EPPVDN). All three sets of guidelines define PH as having a mean pulmonary artery pressure of ≥25 mmHg and accept the validity of the World Health Organization (WHO) classification system. Every child with a high index of suspicion for PH should undergo an initial work-up of chest X-rays, electrocardiography, and echocardiography...

Despite significant efforts to predict and prevent right heart failure, it remains a leading cause of morbidity and mortality after implantation of left ventricular assist systems (LVAS). In this Perspective, we review the underappreciated anatomic and physiologic principles that govern the relationship between left and right heart function and contribute to this phenomenon. This includes the importance of considering the right ventricle (RV) and pulmonary arterial circuit as a coupled system; the contribution of the left ventricle (LV) to RV contractile function and the potential negative impact of acutely unloading the LV; the influence of the pericardium and ventricular twist on septal function; the role of RV deformation in reduced mechanical efficiency after device placement; and the potential of ongoing stressors of an elevated right-sided preload...

BACKGROUND: In severe right heart obstruction (RHO), redistribution of cardiac output to the left ventricle (LV) is well tolerated by the fetal circulation. Although the same should be true of severely regurgitant tricuspid valve disease (rTVD) with reduced or no output from the right ventricle, affected fetuses more frequently develop hydrops or suffer intrauterine demise. We hypothesized that right atrium (RA) function is altered in rTVD but not in RHO, which could contribute to differences in outcomes...

BACKGROUND: Aortic atresia and mitral atresia are predictors of adverse events in early life in patients with hypoplastic left heart syndrome, but it is unclear whether late outcomes are also affected, and whether this impact is related to a small hypertrophied left ventricle (LV) that impairs right ventricle (RV) function. METHODS: Thirty patients with hypoplastic left heart syndrome surviving with a Fontan procedure were identified. Follow-up echocardiograms were available at birth, before the Fontan procedure, and several years after...

OBJECTIVE: The aim of our study was to evaluate the level of agreement between tricuspid annular plane systolic excursion (TAPSE) measured by transthoracic echocardiography (TTE) and TAPSE measured using transesophageal echocardiography (TEE) in anesthetized patients. MATERIALS AND METHODS: Thirty patients scheduled for elective cardiac surgery were prospectively studied. Shortly after induction of anesthesia before the operation, TAPSE was measured by TTE using M-mode in apical 4chamber view (4CH) and by TEE in six different views: using 2D echocardiography in midesophageal (ME) 4CH view, using M-mode in deep transgastric right ventricle (dTG RV) view at 0° and dTG RV longaxis view (LAX) as well as using anatomical M-mode (AM-mode) in ME 4CH, dTG RV at 0° and dTG RV LAX views...

Anomalies of the origin of coronary arteries are detected in 0.5-1.5% of all angiographies. Anomalous origin of the left main trunk is the most uncommon and its origin from pulmonary artery in adults is exceptional, usually because it is associated with a short survival. We report a 49-year-old female, presenting with a two months history of angina. The exercise electrocardiogram suggested ischemia. A coronary angiography was performed, showing the absence of the left main trunk in the left coronary sinus, a dilated right coronary artery, with no lesions and extensive collateral circulation to the anterior descending and circumflex arteries, with inverted flow and the left main trunk draining to the pulmonary artery...

BACKGROUND AND OBJECTIVES: Although the regression of pulmonary hypertension (PH) in mitral stenosis (MS) has been studied over varying periods postintervention, corresponding studies on the cardiac chamber alterations after surgery are very limited. We sought to determine the degree of reversal of these and the clinical status in connection with that of pulmonary artery pressures (PAPs) in the early and late postoperative periods. METHODS: The preoperative, early, and 1-year postoperative data - functional class (FC), cardiothoracic ratio (CTR) in chest X-ray (CXR), and echocardiographically left atrium (LA), right atrium (RA), right ventricle (RV), left ventricle (LV), and pulmonary artery (PA) dimensions, PAP, tricuspid regurgitation (TR) - of 50 patients who had mitral valve replacement (MVR) for MS with PH were retrospectively analyzed for correlations with PAP (Pearson's), and their change (t-test), in relation to that in PAP...

OBJECTIVES: This study sought to investigate the impact of tricuspid regurgitation (TR) on right ventricular function after percutaneous pulmonary valve implantation (PPVI). BACKGROUND: PPVI provides a less invasive alternative to surgery in patients with right ventricular-to-pulmonary artery (RV-PA) conduit dysfunction. Recovery of the right ventricle has been described after PPVI for patients with pulmonary stenosis and for those with pulmonary regurgitation. Additional TR enforces RV dysfunction by supplemental volume overload...
