We report three cases of coronary fistula aneurysm associated with mitral valve insufficiency. The patients were referred to our cardiovascular department because of exertional dyspnea. Echocardiography showed severe mitral valve insufficiency resulting from leaflet flail or prolapse and normal left ventricular function. In all three cases, preoperative coronary angiography showed coronary-to-pulmonary artery fistula associated with significant aneurysm of the fistulous tract. All patients underwent uneventful mitral valve repair and external ligation of the fistulas...

BACKGROUND: Cardiac valve disease is common in patients with end-stage heart failure undergoing left ventricular assist device implantation (LVAD). The aim of this study was to determine if preoperative mitral regurgitation (MR) affects outcomes and hemodynamics in patients after LVAD implantation. METHODS: From March 2006 through May 2015, 238 consecutive patients underwent LVAD implantation. Patient cohorts included less than moderate to severe MR (< moderate-severe, n = 195) and greater than or equal to moderate to severe MR (≥ moderate-severe, n = 43)...

BACKGROUND: Major aortopulmonary collateral arteries (MAPCAs) are frequently found in association with pulmonary atresia with ventricular septal defect (PA/VSD). However, some patients with MAPCAs do not have PA/VSD but have a variety of other "atypical" anatomic diagnoses. METHODS: This was a retrospective review of patients with MAPCAs and atypical anatomy. The 50 patients with MAPCAs could be divided into two subgroups: (1) single ventricle anatomy (n = 33) and (2) two ventricle anatomy (n = 17)...

BACKGROUND: Administration of recombinant erythropoietin (rEPO) is often associated with systemic and pulmonary arterial hypertension in animals and human. The present study was conducted to determine whether one-week rEPO-treatment can produce any effect on pulmonary vasomotor function. METHODS: Male Wistar rats were injected with rEPO (400IU/kg sc) or saline every other day for one week. Tension, biochemical and Real-Time PCR experiments were conducted on left and right branches of pulmonary artery and main pulmonary artery isolated from the rats...

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...

Adaptation to hypoxia requires compensatory mechanisms that affect oxygen (O2) transport and utilization. Decreased hemoglobin (Hb)-O2 affinity is considered part of the physiological adaptive process to chronic hypoxia. This manuscript explores the hypothesis that increased Hb-O2 affinity can complement acute physiological responses to hypoxia by increasing O2 uptake and delivery when compared to normal Hb-O2 affinity during acute severe hypoxia. To test this hypothesis, mice Hb-O2 affinity was increased via oral administration of 70 or 140 mg/kg GBT1118...

BACKGROUND: Little is known on right ventricular (RV) involvement in obstructive sleep apnoea (OSA). This study aimed at evaluating early RV dysfunction by standard and advanced echocardiography in OSA. METHODS: Fifty-nine OSA patients without heart failure and 29 age-matched controls underwent standard, speckle tracking and real time 3D echocardiography of right ventricle. OSA patients performed lung function tests and overnight cardio-respiratory monitoring with evaluation of apnea-hypopnea index (AHI)...

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...

OBJECTIVE: Pulmonary artery branch sealing in video-assisted thoracoscopic surgical lobectomy is usually achieved with vascular endostaplers. Iatrogenic pulmonary artery injury may be caused by endostaplers. We evaluated the safety of pulmonary artery sealing with an ultrasonic energy vessel-sealing device in a phase I clinical trial evaluating in vivo safety of the device during open lobectomy. METHODS: Patients scheduled to undergo elective open (thoracotomy) pulmonary lobectomy were prospectively enrolled...

OBJECTIVES: The hemi-clamshell (HCS) approach consists of partial sternotomy with antero-lateral thoracotomy. This study evaluated the utilities and outcomes of the HCS approach in advanced lung cancer patients. METHODS: We retrospectively investigated 45 patients who underwent surgery for advanced lung cancer via the HCS procedure between 2000 and 2014, the indications for surgery being tumour invasion extending to the aorta arch in 5, descending aorta in 9, main pulmonary artery in 5, superior vena cava in 6, right or left atrium in 4, apical thoracic dome in 7 patients and mediastinal lymphadenopathy for left-sided lung cancer in 12...

OBJECTIVES: Central (aorta) and Sano (right ventricle)-to-pulmonary artery (PA) shunts, palliative operations for infants with complex heart defects, can develop life-threatening thrombosis. We employed computational fluid dynamics (CFD) to study pulsatile flow in these shunts, with the goal to identify haemodynamic characteristics conducive to thrombus formation. METHODS: CFD, using the finite volume method with cardiac catheterization data, and computer simulations, based on angiography, were employed to determine flow-velocity field, wall shear stress (WSS) profile and oscillatory shear index (OSI)...

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...
