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...

Catheterization of laboratory mice is commonly performed in biomedical research to infuse substances and for blood sampling. One approach is to catheterize the right common carotid artery and advance the catheter until the tip is positioned in the aorta or the proximal brachiocephalic trunk. Owing to the small body size of the mouse, a catheter tends to occupy a great part of even the larger vessel lumens, and this may increase vascular resistance with potential pathophysiological impacts on the heart. The present study compared cardiac function of catheterized mice, with catheter tip placement in the brachiocephalic trunk, with sham-operated mice and non-operated control mice...

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...

Regular moderate exercise training is effective for the prevention and treatment of many common chronic diseases and improves cardiovascular health and life expectancy. However, long-term excessive endurance exercise may induce pathological structural remodeling of the heart. The athlete's heart is characterized by enlargement of cardiac chambers and eccentric hypertrophy with preserved myocardial function as normal physiological adaptations for prolonged and intense endurance physical stress. However, recent studies have demonstrated transient right ventricular dysfunction and elevation of cardiac biomarkers following intense endurance exercise...

BACKGROUND: Radiotherapy for breast cancer often involves some incidental exposure of the heart to ionizing radiation. The effect of this exposure on the subsequent risk of heart disease is uncertain. We performed a meta-analysis to investigate the link between radiotherapy and long-term cardiovascular morbidity and mortality in patients with breast cancer. METHODS AND RESULTS: We performed a literature search using MEDLINE (January 1966 to January 2015) and EMBASE (January 1980 to January 2015) with no restrictions...

OBJECTIVES: Double-outlet right ventricle is a form of ventriculoarterial connection. The definition formulated by the International Society for Nomenclature of Paediatric and Congenital Heart Disease is based on hearts with both arterial trunks supported in their greater part by a morphologically right ventricle. Bilateral infundibula and ventricular septal defects are highly debated criteria. This study examines the anatomic controversies surrounding double-outlet right ventricle. We show that hearts with double-outlet right ventricle can have atrioventricular-to-arterial valvular continuity...

In urban populations, worsening renal function (WRF) is well established in patients hospitalized with acute decompensated heart failure with preserved ejection fraction (HFpEF). However, the mechanisms for development of WRF in the setting of acute HF in HFpEF are unclear. In the present study, we sought to characterize conventional echocardiographic measures of right ventricular (RV) chamber size and function to determine whether RV dysfunction and/or adverse RV remodeling is related to WRF in patients with HFpEF...

BACKGROUND: Bilateral adrenalectomy is performed in cases with infantile-onset Cushing syndrome due to bilateral adrenal hyperplasia in McCune-Albright syndrome (MAS) because severe Cushing syndrome with heart failure and liver dysfunction can have a lethal outcome. This procedure can completely ameliorate hypercortisolism, although lifetime steroid replacement therapy and steps to prevent adrenal crisis are necessary. Recently, the efficacy of unilateral adrenalectomy has been reported in adult cases of bilateral macronodular adrenal hyperplasia, but there is no consensus regarding the appropriate surgical treatment for bilateral adrenal hyperplasia in MAS...

Primary cardiac angiosarcomas are frequently found at a large size with infiltration into the adjacent heart structure owing to their asymptomatic characteristics until an advanced stage. Therefore, extensive resection is often required to achieve a good prognosis. We herein report a case of entire circumferential resection of the right atrium surrounded by angiosarcoma and excellent three-dimensional reconstruction of the right atrium.

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: The ascending aorta is an uncommon site for non-infective thrombus. In non-aneurysmal and non-atherosclerotic vessels this condition becomes extremely rare, while it represents a source of potential cerebral and peripheral embolic events. Currently, there is no consensus in the guidelines on how to treat a free floating thrombus in ascending aorta, therefore we present our decision making process and therapeutic strategy. CASE PRESENTATION: A healthy 48-year-old man was hospital admitted with acute abdominal pain...
