OBJECTIVES: Postoperative left pulmonary artery (PA) or bronchus compression occasionally follows narrowing of the retroaortic space after the Norwood procedure. We examined hypoplastic left heart syndrome (HLHS)-specific anatomical malformations and hypothesized that a long main pulmonary arterial trunk might contribute to a larger retroaortic space. In this study, we introduced a modified Norwood procedure [pulmonary artery trunk-saving method (PATS)] and evaluated the results. METHODS: HLHS-specific anatomical malformations were examined using computed tomographic data from 23 consecutive patients who underwent bilateral pulmonary banding...

BACKGROUND: Controversy remains regarding the optimal surgical approach for children with supravalvular aortic stenosis (SVAS). METHODS: Since 1997 we have used Brom three-patch aortoplasty for patients with SVAS. We prefer computed tomography (CT) imaging for preoperative evaluation rather than cardiac catheterization as it avoids the well-known morbidity of general anesthesia. The purpose of this study was to present our intermediate-term results of this strategy...

Deletion of 22q11.2 (del22q11) is associated with adverse outcomes in patients with tetralogy of Fallot (TOF). We sought to investigate its contribution to perioperative outcome in patients with a severe form of TOF characterized by pulmonary atresia (PA) or severe pulmonary stenosis (PS) and major aortopulmonary collateral arteries (MAPCAS). We conducted a retrospective review of patients with TOF/MAPCAS who underwent staged surgical reconstruction between 1995 and 2006. Groups were compared according to 22q11...

Right ventricular-dependent coronary circulation (RVDCC) is associated with pulmonary atresia with intact ventricular septum and is defined by two or more epicardial coronary arteries with atresia or severe stenosis resulting in the dependency of coronary supply by retrograde flow. The hypothesis of this study is that coronary Doppler flow patterns on echocardiography can be used to distinguish patients with RVDCC. Between 2007 and 2016, we reviewed 16 patients with pulmonary atresia or critical pulmonary stenosis...

We present the case of a 72-year-old woman diagnosed with rheumatic fever at the age of 6. In 1972, she was diagnosed with mitral valve insufficiency and mitral valve stenosis, then in 1974, a decision was made to perform mitral valve replacement surgery with a 32-mm Braunwald-Cutter ball cage prosthesis. An echocardiogram performed in 2014 revealed normal biventricular systolic function, mechanical prosthesis in mitral position with maximum speed of 1.9 m/s, maximum gradient of 15 mmHg, mean gradient of 6 mmHg, severe tricuspid valve insufficiency, inferior vena cava measuring 15 mm with more than 50% collapse and pulmonary artery systolic pressure of 40 mmHg...

Polyarteritis nodosa (PAN) is an inflammatory vasculitis that creates regions of stenosis and aneurysm formation. The authors describe a 66-year-old female with hepatic artery rupture as the first presentation of undiagnosed PAN, presenting with abdominal pain followed by hemorrhagic shock. This aneurysm was suture ligated with a successful outcome. A mesenteric arteriogram demonstrated lesions consistent with PAN including aneurysms of the left gastric branches, right and left hepatic arteries, and beaded appearance of the iliac artery...

OBJECTIVES: This study was performed to analyse the impacts of functional mitral stenosis (MS) following mitral valve (MV) repair on late cardiac function and new onset of atrial fibrillation or survival. METHODS: We retrospectively reviewed 602 patients with mitral regurgitation who underwent MV repair for Type II dysfunction from 2001. Functional MS was diagnosed when the mean transmitral pressure gradient (MTPG) was ≥5 mmHg on postoperative echocardiography...

BACKGROUND: Exposure to crystalline silica results in silicosis with initiation and progression of pulmonary fibrosis. The impaired lung parenchyma leads to pulmonary arterial hypertension and increased pressure in the right ventricle of the heart. Usually, the silicosis may be followed by enlargement of hilar lymphnodes, but silicosis-induced pulmonary artery stenosis with severe pulmonary hypertension is rare. Percutaneous pulmonary artery stenting and balloon angioplasty were performed to relieve stenosis and pulmonary hypertension...

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...

BACKGROUND: The Inoue balloon technique is the standard technique for mitral valve balloon commissurotomy at this stage. However, the hardware for this technique is expensive and may not always be available in resource-limited settings. OBJECTIVE: This article reports our experience with percutaneous transmitral balloon commissurotomy using a single balloon (Nucleus) with arteriovenous loop stabilisation. METHOD: Eleven young patients, aged 12-26 years and weighing 23-48 kg, underwent transmitral balloon commissurotomy using the described technique at our centre from April to May 2014...

An elderly male patient with coronary heart disease underwent coronary angiography, which revealed bilateral severe coronary artery stenosis. Four stents were implanted, and at 5 h post-surgery, typical hemorrhagic shock appeared. Echocardiography verified heavy bleeding in the right thoracic cavity. Emergency angiography excluded injury or perforation of the coronary artery, aorta, right subclavian artery and brachiocephalic artery. Considering the patient's history of chronic obstructive pulmonary disease and severe cough during the operation, it was suspected that hemothorax was induced by a blood vessel rupture in the pleura...

BACKGROUND CONTEXT: Postoperative Urinary Retention (POUR) is a very common post-operative complication of all surgeries (5 - 70%) that may lead to complications such as urinary tract infection (UTI), bladder over-distention, autonomic dysregulation, and increased postoperative length of stay (LOS). Within the field of spine surgery, the reported incidence of POUR is highly variable (5.6 - 38%). Lack of clear stratification of surgical level, spinal pathology, and inadequate sample size is a major limitation of available studies concerning POUR following spine surgery that may lead to inconsistency in the incidence of POUR and the ability to model its occurrence and consequences...

Aortic stenosis (AS) is the most common type of valvular heart disease in the elderly. Surgical aortic valve replacement (SAVR) has been the standard practice for treating severe, symptomatic AS, but recently new treatment options have emerged. Transcatheter aortic valve replacement (TAVR) is now an established treatment option in patients at high surgical risk. In this review, we focus on recent developments and compare the two treatment methods in specific populations in terms of efficacy and safety (e.g...

We present a very rare case of isolated right pulmonary veins atresia in a 4-year-old girl. As the presence of a pulsatile blind pulmonary venous confluence adjacent to the left atrium was demonstrated by preoperative right pulmonary arterial wedge angiography, we applied sutureless pericardial marsupialization for the repair of right pulmonary veins atresia. She is currently 8 years old without pulmonary veins stenosis.
