AIM: To analyze the results of tracheal resection for cicatricial stenosis depending on the presence of tracheostomy. MATERIAL AND METHODS: 1128 patients with tracheal cicatricial stenosis were treated for the period 1963-2015. The first group consisted of 297 patients for the period 1963-2000, the second group - 831 patients for the period 2001-2015. Most of them 684 (60.6%) were young and able-bodied (age from 21 to 50 years). In the first group 139 (46.8%) out of 297 patients had functioning tracheostomy...

BACKGROUND: The indications for pediatric coronary revascularization are diverse. There are a large proportion of patients with sequelae of severe inflammatory diseases such as Kawasaki disease, and other less common causes. METHODS: Retrospective review of ten pediatric patients undergoing coronary artery bypass surgery from January 2004 to December 2016. RESULTS: Ten children and adolescents ranging in age from 2 to 17 (median, 6) years at operation were followed up for as long as 13 years with a median follow-up of 2 years...

Bland-White-Garland (BWG) syndrome (anomalous origin of the left coronary artery from the pulmonary artery) is a rare disease which may result in myocardial infarction, congestive heart failure or sometimes death during the early infantile period. We present a 57-year-old female with BWG syndrome. At the age of 20, she was diagnosed with BWG syndrome and underwent coronary artery bypass grafting of a saphenous vein to the proximal portion of the anterior descending branch of the left coronary artery and ligation of the anomalous artery...

A 62-year old male with pulmonary fibrosis and aortic valve stenosis underwent TAVI (Corevalve Evolut XL 34 mm) in the build-up for lung transplantation (LuTx). Following post-dilation for a large annular perimeter, moderate paravalvular aortic regurgitation (AR) was observed. After 6 weeks, he was admitted to the ICU with respiratory failure(A). TTE demonstrated residual mild AR (based on a small excentric paravalvular AR jet, <10% circumferential extent, pressure half-time was not reliably measured) and together with borderline elevated NT-pro-BNP, the consultant cardiologist authorized LuTx listing...

INTRODUCTION: Localized pericardial constriction is a rare form of constrictive pericarditis CP. Depending on the CP location, clinical presentation may be variable, including compression and obstruction of right ventricular inflow tract(RVIT), coronary obstruction, or pulmonary stenosis. CASE PRESENTATION: A 72-year-old man presented a 2-year history of dyspnea and atrial fibrillation. A contrast enhanced angio computerized tomography clearly demonstrated a large spherical mass about 11×9×4cm in the anterior pericardium, presenting as a mediastinal tumor causing compression and obstruction of the RVIT...

BACKGROUND: Low-gradient severe aortic stenosis (LGSAS) with preserved ejection fraction (EF) is incompletely understood. The influence of arterial afterload and diastolic dysfunction on the hemodynamic presentation of LGSAS remains unknown. OBJECTIVES: The authors sought to determine the acute hemodynamic response to sodium nitroprusside in LGSAS with preserved EF. METHODS: Symptomatic patients with LGSAS and preserved EF underwent cardiac catheterization with comparison of hemodynamic measurements before and after nitroprusside...

A 1-month-old, 2.4 kg infant, previously born at 32 weeks gestation, was found to have a murmur while in the neonatal intensive care unit. The patient had ongoing feeding intolerance and required supplemental oxygen via nasal cannula. Cardiac computed tomography showed discrete stenosis of the proximal left pulmonary artery (LPA) with a normal-sized distal LPA. We describe the treatment course with transcatheter coronary stent implantation.

BACKGROUND: Systemic-to-pulmonary shunts are useful palliative procedures, although many teams have been deterred by high mortality and morbidity. We aimed to identify predictors of adverse outcomes after shunts in biventricular lesions. METHODS: From 2004 to 2014, 173 children had shunt procedures. Morphologies included: tetralogy of Fallot, pulmonary atresia with ventricular septal defect (VSD) with and without major aortopulmonary collaterals (MAPCAs), transposition of great arteries with pulmonary stenosis, and double outlet right ventricle...

Takayasu's arteritis is a rare systemic vasculitis mainly affecting the aorta and its major branches. Previous studies have suggested that almost half of the Asian Takayasu's patients have renal artery involvement. However, due to the rarity of the disease, little is known about renal artery involvement in Chinese Takayasu's arteritis patients. Here, we retrospectively reviewed and analyzed 411 patients diagnosed with Takayasu's arteritis in our center to explore the clinical features of renal artery involvement in this group of patients...

There is an old adage in paediatric cardiology that, despite the high prevalence and wide spectrum of CHD, transposition of the great arteries does not occur in trisomy 21. We present a case of transposition of the great arteries, ventricular septal defect, and pulmonary stenosis in a patient with trisomy 21.

BACKGROUND Pulmonary arterial hypertension (PAH) results from proliferative vasculopathy involving all layers of the blood vessel. Similar findings may be present in pulmonary hypertension (PH) associated with microscopic tumor embolism, which are thought to be related to the phenomenon of pulmonary tumor thrombotic microangiopathy (PTTM). PTTM is associated with the activation of the coagulation system at the surface of the tumor emboli, resulting in stenosis or occlusion of the vessel.

Studies regarding long-term results after repair of anomalous left main coronary artery from the pulmonary artery (ALCAPA) have mainly focused on survival rates, left ventricular function, and mitral valve function. The development of left main coronary stenosis following repair has been infrequently reported and its incidence unknown. Optimal therapy is also not known. Here we report the use of surgical angioplasty to achieve revascularization of a stenotic left main coronary artery in a patient with ALCAPA who had undergone coronary transfer 15 years earlier...

BACKGROUND: Transpulmonary thermodilution is recommended in the treatment of critically ill patients presenting with complex shock. However, so far it has not been validated in hemodynamically stable patients with heart disease. METHODS: We assessed the validity of cardiac output, global end-diastolic volume index (GEDVI), an established marker of preload thought to reflect the volume of all four heart chambers, global ejection fraction (GEF) and cardiac function index (CFI) as variables of cardiac function, and extravascular lung water index (EVLWI) as indicator of pulmonary edema in 29 patients undergoing elective left and right heart catheterization including left ventricular angiography with stable coronary heart disease and normal cardiac function (controls, n = 11), moderate-to-severe aortic valve stenosis (AS, n = 10), or dilated cardiomyopathy (DCM, n = 8)...

A man aged 83 years under treatment with enzalutamide for castration-resistant prostate cancer presented with general malaise and exertional dyspnea. The underlying cause could not be identified by further investigations. On the 5th hospital day, he died due to a sudden exacerbation of dyspnea. The results of an autopsy indicated tumor emboli and stenosis of small pulmonary arteries with the fibrocellular intimal thickening, and therefore our final diagnosis was pulmonary tumor thrombotic microangiopathy.

Terumoto Koike, Masanori Tsuchida
For general thoracic surgeons, perioperative management for prevention of cardiac complications is important because patients undergoing general thoracic surgery often have risk factors for cardiac disease. Sever cardiac failure should be detected and treated prior to surgery, and coronary artery may be examined in patients with risk factors for ischemic heart disease. Pulmonary resection sometimes causes right-sided heart failure due to reducing pulmonary vascular bed. In high-risk patients for rightsided heart failure, pulmonary artery pressure monitoring by right heart catheterization should be considered in addition to blood pressure and central venous pressure monitoring, and precise fluid management is required...

BACKGROUND: Renal artery stenosis (RAS) has a high prevalence in older patients, especially in the context of general atherosclerosis. It is frequently associated with resistant hypertension and impaired renal function and their attendant consequences. The issue whether revascularization via percutaneous renal angioplasty and stenting (PRA/S) can benefit these patients remains unsettled. OBJECTIVE: To present a case series of patients with refractory hypertension and RAS undergoing PRA/S and also to provide an extensive review of the literature on the current status of PRA/S for resistant hypertension...

Renal artery stenosis may play a significant role in the pathogenesis of secondary hypertension, renal dysfunction, and flash pulmonary edema. Currently correction of renal arterial inflow stenosis is reserved for resistant hypertension patients who have failed maximal medical therapy, have worsening renal function and/or unexplained proximal congestive failure. With the recent advances in minimally invasive percutaneous stent placement techniques, open surgical revascularization has been largely replaced by renal artery stenting...
