Background Increased pulmonary blood flow (PBF) and shear stress may provoke irreversible vascular remodeling, yet invasive visualization of the microvasculature complicates monitoring. A non-invasive imaging methodology would therefore safely provide mechanistic insights into the progression of high PBF-induced vascular remodeling. Purpose To establish a novel microvasculature visualization method using synchrotron radiation pulmonary microangiography (SRPA) that can also calculate PBF velocity in vivo. Material and Methods A high PBF rat model was established by making a fistula between the abdominal aorta and inferior vena cava...

BACKGROUND: To evaluate the ability of low radiation dose dual-source computed tomography (DSCT) to depict the features of morphological univentricular heart and to define accuracy by comparing findings with surgery. METHODS: Low radiation dose dual-source cardiac computed tomography (CCT) of 33 cases of functional univentricular heart preliminary diagnosis by echocardiography compared with the results of surgery were retrospectively analyzed (aged 1 day to 4 years, median 5 months)...

BACKGROUND: Lung stereotactic body radiotherapy (SBRT) is considered a standard curative treatment for medically inoperable early stage non-small-cell lung cancer (NSCLC). Patients with ultracentral tumors (signifying tumors whose planning target volume touches or overlaps the central bronchial tree, esophagus, or pulmonary artery) may be at higher risk of serious toxicities such as bronchial stricture and collapse, esophageal strictures, tracheal-esophageal fistula, and hemorrhage. The primary objective of the study is to determine the maximum tolerated dose of radiotherapy for ultracentral NSCLC...

A 29-year-old male with chronic pulmonary emboli presented to hospital with progressive pleuritic chest pain. He was in acute right ventricular failure, and thus underwent intra-pulmonary arterial tissue plasminogen (tPA). He developed massive hemoptysis requiring emergent thromboendarterectomy. A clot was visualized in the main left pulmonary artery which had formed a bronchovascular fistula into the left upper lobe bronchus. Pathology of the clot revealed fibrinopurulent exudate and Gram-positive cocci. The left pulmonary artery was repaired with a pericardial patch, and the left upper lobe was oversewn with subsequent left upper lobectomy...

Coronary artery fistula is a rare anomalous connection between a coronary artery and a cardiac chamber or major vessel. Here we present the case of a 36-year-old woman who presented with sharp, substernal chest pain, dyspnea, and dizziness. A fistula between her left anterior descending artery and pulmonary trunk was found. Herein, we describe our approach and review the epidemiology, pathophysiology, diagnosis, and treatment options.

Outcome data for neonates with critical pulmonary stenosis (PS) is limited. We aimed to review the outcomes after balloon pulmonary valvuloplasty (BPV) for neonates with critical PS at our institution. All neonates with critical PS who underwent BPV from 1990 to 2017 were included. A total of 44 neonates underwent BPV for critical PS. Nonright ventricular dependent coronary artery fistulas was seen in 6/44 (13.6%) patients. Tricuspid valve z-scores were -1.9 (interquartile range [IQR] -3.04, -0.48) in those with coronary artery fistulas as compared with -0...

BACKGROUND: One-stage closure and fenestration are the available surgical options for bronchopleural fistula (BPF). One-stage closure may be applicable in cases with favorable infection control. Closing the bronchopleural stump is difficult due to thick adhesion caused by inflammation and a high risk of pulmonary artery injury. We report the successful closure of a BPF using a gastric seromuscular patch with an omental pedicle flap. CASE PRESENTATION: A 73-year-old man underwent right lower lobectomy with ND2a-2 lymph node dissection for lung adenocarcinoma...

BACKGROUND: Coronary fistulae are occasionally detected using echocardiography or coronary angiography. We report a patient with cardiac tamponade because of a ruptured aneurysm of a coronary artery fistula. CASE PRESENTATION: A 60-year-old man was referred to our hospital with sudden onset of chest pain and unconsciousness. He was initially diagnosed with cardiac tamponade for type A acute aortic dissection, and an emergency operation was performed. A large amount of bleeding was seen in the pericardium, but aortic dissection around the arch was not observed...

Recent applications of Computational Fluid Dynamics (CFD) applied to the cardiovascular system have demonstrated its power in investigating the impact of hemodynamics on disease initiation, progression, and treatment outcomes. Flow metrics such as pressure distributions, wall shear stresses, and blood velocity profiles can be quantified to provide insight into observed pathologies, assist with surgical planning, or even predict disease progression. While numerous studies have performed simulations on clinical human patient data, it often lacks pre-diagnosis information and can be subject to large inter-subject variability, limiting the generalizability of findings...

Objective: To investigate the feasibility and efficacy of transcatheter closure of anastomotic leakage after aortic surgery using Amplatzer Vascular Plug Ⅲ (AVP Ⅲ). Methods: A retrospective analysis was performed in 5 patients with anastomotic leakage after aortic surgery, who underwent transcatheter closure in our hospital from January to June 2017 using AVP Ⅲ. Surgeries were performed in 3 cases of Standford type A dissection, 1 case of ascending aortic aneurysm and 1 case of persistent truncus.There were 3 males,and age was (43...

We present the case of a 54-year-old male patient diagnosed with a right upper lobe lung cancer and was referred for resection. Positron emission tomography-computed tomography scan showed a prominent vascular structure in the right lung, suspicious for vascular malformation. A computed tomography angiography was done, demonstrating an intercostobronchial trunk-pulmonary artery fistula. There was also non-tapering dilated wandering pulmonary artery coursing through the right lower lung without any abnormal connection with pulmonary veins and were supplying normal lung parenchyma...

Giant coronary artery aneurysms related to coronary fistula are rare, and the precise mechanisms by which they occur are unknown. We present a case of giant coronary artery aneurysm of the left coronary artery to the pulmonary artery fistula with a lack of internal and (or) external elastic lamina and medial degeneration.

Branch pulmonary artery stenosis is one of the most common complications late after the arterial switch operation. The pathophysiology of stenosis in these circumstances is very different to that encountered in with normally related great vessels. The LeCompte manoeuvre leaves the pulmonary arteries straddled and stretched over the aortic root which contributing significantly to the degree of stenosis encountered. Unilateral branch pulmonary artery stenosis rarely leads to significant symptoms in young patients with biventricular repairs; however, significant discrepancies in the split flows between right and left lung may place the patient in an unfavourable physiological position as they move in to middle age...

We report a rare case of right heart failure caused by distal aortic aneurysm. Although aortopulmonary fistula is a common complication of giant aortic arch aneurysm, right heart failure caused by mechanical pressure by aneurysm is very rare. A 79-year-old female patient presented dyspnea. Contrast computed tomography (CT) of the thorax delineated a 78 mm aortic arch aneurysm pressing the main to left pulmonary artery and a 40 mm pericardial effusion at maximum depth at posterior side. Echocardiography showed the acceleration flow from main to left pulmonary artery and moderate pulmonary hypertension...

A 39-year-old Japanese woman was diagnosed with a pulmonary arteriovenous fistula (PAVF) complicated by paradoxical cerebral infarction during pregnancy. She received an inferior vena cava filter (IVCF), but it was difficult to indwell because of the risk of repeat thromboembolism via PAVF. Therefore, we temporarily occluded the pulmonary artery with a balloon to prevent free thrombi from reaching the IVCF. Detection and treatment of PAVF are recommended in fertile young women. Obstruction of the pulmonary artery trunk with a balloon catheter may be useful during IVCF removal in patients with untreated PAVF...
