Incontinentia pigmenti (IP; Bloch-Sulzberger syndrome) is a rare, genetic syndrome inherited as an X-linked dominant trait. It primarily affects female infants and is lethal in the majority of males during fetal life. The clinical findings include skin lesions, developmental defects, and defects of the eyes, teeth, skeletal system, and central nervous system. Cardiovascular complications of this disease in general, and pulmonary hypertension in particular, are extremely rare. This report describes the case of a 3-year-old girl with IP complicated by pulmonary arterial hypertension...

OBJECTIVES: The relationship between left ventricular function and afterload has not been investigated as much as the right ventricular function under chronic pulmonary hypertension (PH) during anesthesia. This study was designed to investigate effects of sevoflurane on the intrinsic coupling relationship between the left ventricle and systemic vasculature in the presence of PH. DESIGN: A randomized, controlled study. SETTING: University hospital...

Change in 6-minute walk distance (6MWD) has been used as a clinical marker in pulmonary hypertension. Determinants and worsening of 6MWD remain a matter of debate because nonpulmonary factors have an impact on the 6MWD. We hypothesized that future reduction of 6MWD in patients with systemic sclerosis (SSc) was more closely associated with cardiac dysfunction. We prospectively performed standard clinical and echocardiographic evaluations in SSc patients with the 6-minute walk test at enrollment. Features associated with the 6MWD were sought in a multiple linear regression analysis and compared using standardized β...

We present a rare case in an elderly Caucasian lady of primary ovarian carcinoid tumor, causing symptoms of the carcinoid syndrome and severe carcinoid heart disease. Carcinoid tumors are the commonest neuroendocrine tumors, the majority of which are found in the gastrointestinal tract and lungs. Ovarian carcinoids represent only 0.1% of all ovarian neoplasms and 1% of all carcinoid tumors. Carcinoid syndrome can present with flushing, diffuse watery diarrhea, wheezing and breathlessness and in advanced cases lead to carcinoid heart disease...

Aims: Many patients with heart failure with preserved ejection fraction (HFpEF) develop post-capillary pulmonary hypertension (PH) due to increased left-sided filling pressures. However, a subset of patients develops combined post- and pre-capillary PH. We studied the value of echocardiographic right-sided characterization for the discrimination between pre- vs. post-capillary PH in HFpEF, using invasive haemodynamics as gold standard. Methods and results: 102 consecutive HFpEF patients with simultaneous right heart catheterization and echocardiography were identified...

Over the past decade, there has been a major shift in chemotherapy from non-specific cytotoxic drugs to molecular targeted drug therapies. As more molecular targeted therapies are developed, new types of cardiovascular toxicities induced by targeted therapies are a growing problem. Cardiotoxicity induced by the human epidermal growth factor receptor-2 inhibitor trastuzumab manifests as decreased left ventricular ejection fraction. In contrast to anthracycline treatment, most cardiac events occur during trastuzumab treatment, but are reversed quickly when treatment is interrupted and cardiac intervention is established...

Pulmonary arterial hypertension is a progressive disease that culminates in right heart failure and death. Prostacyclin(PGI2) and its derivatives are effective treatments for PAH when administered as continuous parenteral infusions. This treatment paradigm requires medical sophistication, and patients are at risk for complications from an indewelling catheter; drug interruptions may result in rebound pulmonary hypertension and death. We hypothesized that the salivary gland can be repurposed into an endogenous production site for circulating PGI2 through the expression of a fusion protein embodying cyclooxygenase-1(Cox1) and prostacyclin synthase(PGIS) domains...

BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare, distinct pulmonary vascular disease, and, therefore, there is lack of data regarding its clinical presentation, diagnosis and management at a national basis. Our objective was to describe the demographics and management of CTEPH patients in Northern Greece. METHODS: We conducted a retrospective, observational study with a joint collaboration from two pulmonary hypertension expert centers in Greece and included patients diagnosed with CTEPH...

BACKGROUND: Since 2006 and 2007, patients in France with severe pulmonary hypertension (PH) who are at imminent risk of death, despite optimal treatment in the intensive care unit, are placed on a high-priority list (HPL) for heart-lung transplantation (HLT) or double-lung transplantation (DLT). We assessed the effect of this approach on the waiting list and outcomes after transplantation. METHODS: We conducted a single-center, retrospective, before-and-after study of consecutive patients with severe group 1, 1', or 4 PH listed for DLT or HLT between 2000 and 2013 (ie, 6 years before and 6 years after HPL implementation)...

BACKGROUND: Surgical lung biopsy contributes to establishing a specific diagnosis among many patients with interstitial lung disease (ILD). The risks of death and respiratory failure associated with elective thoracoscopic surgical lung biopsy, and patient characteristics associated with these outcomes, are not well understood. METHODS: This is a retrospective cohort study of patients who underwent elective thoracoscopic lung biopsy for ILD between 2008 and 2014, according to The Society of Thoracic Surgeons database...

BACKGROUND: Pulmonary hypertension (PH) is diagnosed and classified through right heart catheterization (RHC), with a number of hemodynamic markers used to help guide treatment decisions. These markers may not reflect the complex remodeling of the right ventricle or the interplay between ventricles, and struggle to predict treatment response. This study investigates the use of a novel marker; the ratio of left to right ventricular end-diastolic pressures (LVEDP/RVEDP), in predicting treatment outcomes in a cohort of PH patients...

Pulmonary arterial hypertension (PAH) is progressive disorder characterized by elevated pulmonary vascular resistance that can lead to right heart failure and death. One of the main therapeutic options for PAH are medications targeting the prostacyclin pathway. Treprostinil is a prostacyclin analogue and selexipag is a selective IP receptor agonist. Treprostinil can be delivered by a variety of routes including oral, inhaled, subcutaneous and intravenous. Selexipag is currently approved as an oral formulation...

Although measurement of right ventricular ejection fraction (RVEF) may be relevant for evaluation of therapeutic efficacy and/or prognosis in patients with pulmonary hypertension, RVEF obtained by echocardiography has limited accuracy. In contrast, radionuclide and/or magnetic resonance imaging can measure RVEF more reliably. In this study, we investigated the relationship between RVEF measured by radionuclide angiography and the echocardiographic parameters that are recommended by the American Society of Echocardiography as representative of right heart function...

BACKGROUND: For treatment of chronic thromboembolic pulmonary hypertension (CTEPH), the evaluation of segmental pulmonary perfusion is important. There are no previous reports about lung subtraction iodine mapping (LSIM) computed tomography (CT) for evaluation of segmental pulmonary perfusion in patients with CTEPH, using lung perfusion SPECT/CT (LPS) as the reference. METHODS: 50 patients (age, 60.7±16.7years) with known or suspected CTEPH were enrolled in this study...

Pulmonary hypertension (PH) is a complex disease process of the pulmonary vasculature system characterized by elevated pulmonary arterial pressures. Patients with PH are at increased risk for morbidity and mortality, including intraoperatively and postoperatively. Appreciation by the clinical anesthesiologist of the pathophysiology of PH is warranted. Careful and meticulous strategy using appropriate anesthetic medications, pulmonary vasodilator and inotropic agents, and careful fluid management all increase the likelihood of the best possible outcome in this challenging patient population...

Pulmonary hypertension is defined by a mean pulmonary artery pressure ≥25 mm Hg at rest. Management of pulmonary arterial hypertension (PAH) includes specific drug therapy with calcium channel blockers in vasoreactive patients, or drugs approved for PAH in non-reactive patients that target the endothelin, nitric-oxide and prostacyclin pathways. Areas covered: The review covers receptor selectivity, pharmacokinetics, pharmacodynamics and adverse effects (AEs) of intravenous (IV) epoprostenol (synthetic prostacyclin); the prostacyclin analogs iloprost, beraprost, and treprostinil administered by IV, subcutaneous, inhaled or oral routes; and the oral selective prostacyclin receptor agonist selexipag...

Pulmonary arterial hypertension (PAH), at one time a largely overlooked disease, is now the subject of intense study in many academic and biotech groups. The availability of new treatments has increased awareness of the condition. This in turn has driven a change in the demographics of PAH, with an increase in the mean age at diagnosis. The diagnosis of PAH in more elderly patients has highlighted the need for careful phenotyping of patients and for further studies to understand how best to manage pulmonary hypertension associated with, for example, left heart disease...

Sulfur dioxide (SO₂) is a toxic gas and air pollutant. The toxic effects of SO₂ have been extensively studied. Oxidative damage due to SO2 can occur in multiple organs. Inhaled SO₂ can also cause chromosomal aberrations, DNA damage and gene mutations in mammals. However, SO₂ can also be generated from the sulfur-containing amino acid, L-cysteine. Recent studies have shown that SO₂ has a vasorelaxant effect, and ameliorates pulmonary hypertension and vascular remodeling. SO₂ can also reduce lung injury and myocardial injury in rats...
