BACKGROUND: The optimal interval between serial cardiac magnetic resonance imaging (CMRI) scans for monitoring right ventricular (RV) enlargement in the setting of severe pulmonic valve regurgitation (PR) is unknown. The purposes of this study were to (1) determine the annual change in RV volume on serial CMRI scans and (2) identify the risk factors for rapid progression of RV enlargement. METHODS: A retrospective study of adults with postintervention native valve PR and ≥2 CMRI scans at Mayo Clinic Rochester from 2000 to 2015 was conducted...

BACKGROUND: An anomalous muscle bundle crossing the right atrial cavity represents a pathological finding with unproved clinical significance. This congenital anomaly may be difficult to recognize via echocardiography and could be confused with other intra-cavitary lesions. METHODS: We report a case of a 53-year-old female presented to the cardio-vascular service with acute superior vena cava syndrome and sub-massive pulmonary embolism. RESULTS: The patient underwent venography confirming superior vena cava stenosis...

BACKGROUND: Decompression surgery for lumbar spinal stenosis (LSS) is the most common spinal procedure in the elderly. To avoid persisting low back pain, adding arthrodesis has been recommended, especially if there is a coexisting degenerative spondylolisthesis. However, this strategy remains controversial, resulting in practice-based variation. PURPOSE: To evaluate in a pragmatic study if surgical selection criteria and variation in use of arthrodesis in three Scandinavian countries can be linked to variation in treatment effectiveness...

Surgical treatment of stenosis of the laryngotracheal junction can be challenging. Success is not only measured by the patency of the airway but also by preservation of the full functional capacity of the larynx. This unique feature of subglottic resections requires a close cooperation with speech-language pathologists and ENT specialists.

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is a less invasive treatment modality for patients with severe aortic valve stenosis (AS) who are at a higher risk if they have surgery. Preoperative chronic kidney disease (CKD) influences outcomes of cardiac surgery and is associated with a higher mortality and more complicated hospital course. The aims of our study were to evaluate the comparative outcomes of TAVI versus surgical aortic valve replacement (SAVR) in geriatric patients with preoperative CKD...

Total thyroidectomy, radioiodine (RAI) therapy, and TSH suppression are the mainstay treatment for differentiated thyroid carcinomas (DTCs). Treatments for metastatic disease include surgery, external-beam radiotherapy, RAI, and kinase inhibitors for progressive iodine-refractory disease. Unresectable locoregional disease remains a challenge, as standard therapy with RAI becomes unfeasible. We report a case of a young patient who presented with unresectable papillary thyroid carcinoma (PTC), and treatment with sorafenib allowed total thyroidectomy and RAI therapy...

Purpose Incidental cardiac irradiation can cause cardiac injury, but little is known about the effect of radiation on specific cardiac segments. Methods For 456 women who received breast cancer radiotherapy between 1958 and 2001 and then later experienced a major coronary event, information was obtained on the radiotherapy regimen they received and on the location of their cardiac injury. For 414 women, all with documented location of left ventricular (LV) injury, doses to five LV segments were estimated. For 133 women, all with documented location of coronary artery disease with ≥ 70% stenosis, doses to six coronary artery segments were estimated...

BACKGROUND: The differentiation between intracranial atherosclerotic stenosis (ICAS) and intracranial embolism as the immediate cause of acute ischemic stroke requiring endovascular therapy is important but challenging. In cases of ICAS, we often observe a phenomenon we call the microcatheter "first-pass effect," which is temporary blood flow through the occluded intracranial artery when the angiographic microcatheter is initially advanced through the site of total occlusion and immediately retrieved proximally...

New techniques have been developed to treat severe anastomotic strictures after rectal surgery. This report describes a new approach using transanal minimally invasive surgery for the treatment of complete anastomotic occlusion. A 49-year-old man presented with a completely occluded anastomosis after low anterior resection with temporary ileostomy for rectal cancer. The lumen was completely obstructed with a blind wall. A transanal surgical approach was used to treat the obstruction. Water-soluble radiopaque contrast medium was injected intraoperatively to identify the proximal lumen, and an incision was made by electrocautery until the luminal diameter was sufficient...

AIMS: Randomised controlled trials have reported instantaneous wave-free ratio (iFR) to be non-inferior to fractional flow reserve (FFR) for major adverse cardiovascular events at one year; however, iFR is limited by sensitive landmarking of the pressure waveform, and the assumption that maximal flow and minimal resistance occur during a fixed period of diastole. We sought to validate the resting full-cycle ratio (RFR), a novel non-hyperaemic index of coronary stenosis severity based on unbiased identification of the lowest distal coronary pressure to aortic pressure ratio (Pd/Pa), independent of the ECG, landmark identification, and timing within the cardiac cycle...

The non-vitamin K antagonist oral anticoagulants (NOACs), which include dabigatran, apixaban, edoxaban and rivaroxaban, are preferred over vitamin K antagonists for stoke prevention in most patients with non-valvular atrial fibrillation. The NOACs are contraindicated in atrial fibrillation patients with rheumatic mitral stenosis or mechanical heart valves. There is evidence that bioprosthetic heart valves are less thrombogenic than mechanical heart valves, but it is unknown whether the risk of thromboembolism in atrial fibrillation patients with bioprosthetic valves differs from that in patients without such valves...

Vertebral compression fractures (VCFs) may result in a kyphotic deformity which can cause potential systemic complications secondary to respiratory and gastrointestinal dysfunction. The use of implants in the spine for VCF treatment represents a paradigm shift away from cement injection on its own, aiming to combine the analgesic and stabilizing effect of injecting cement into the vertebral body with vertebral height restoration and kyphotic angle correction. Spine implants which can be used for VCF treatment include stents, jacks, PEEK cages and fracture reduction systems...

OBJECTIVE: The objective of this study was to evaluate 30-day and long-term clinical outcomes and influencing factors of in-stent restenosis (ISR) after stenting for symptomatic stenosis of the vertebral V1 segment. METHODS: The clinical and follow-up data of 301 consecutive patients (mean age, 64 ± 8 years; 252 men) with symptomatic V1 stenosis who underwent stenting at the Fuwai Hospital between January 2010 and June 2016 were collected retrospectively. The 30-day and long-term follow-up of stroke and death after stenting and the recurrence of symptoms, ISR, and repeated revascularization were assessed...

BACKGROUND: Cardiological societies recommend, in their guidelines, that patients with atrial fibrillation and an intermediate (or higher) risk of stroke and systemic embolization should be treated with oral anticoagulant drugs. For patients who do not have mitral valve stenosis or a mechanical valve prosthesis, non-vitamin-K dependent oral anticoagulants (NOAC) are preferred over vitamin K antagonists (VKA) for this purpose. It is unclear, however, whether patients with chronic kidney disease and atrial fibrillation benefit from oral anticoagulation to the same extent as those with normal kidney function...

Objectives Although a clear relationship has been demonstrated between the presence of lumbosacral transitional vertebrae and the development of lumbosacral stenosis in dogs, this relationship has not been evaluated in cats. The aim of this study was to investigate the relationship between the presence of lumbosacral transitional vertebrae and lumbosacral stenosis in cats. Methods The medical records and diagnostic imaging studies of 13 cats diagnosed with lumbosacral stenosis were retrospectively reviewed for lumbosacral abnormalities and compared with findings of 405 cats that underwent CT for reasons unrelated to spinal disease...

Background Dissection of the internal carotid artery (ICA) can cause occlusion or severe stenosis and is known to be one of the major causes of ischemic stroke in the young. Endovascular treatment is one of the useful options for carotid dissections, but passing the guidewire through the occlusion (lesion-cross) and confirmation of the true lumen are sometimes difficult. Case presentation A 40-year-old right-handed man complaining of dysarthria and gait disturbance consulted our hospital. Magnetic resonance imaging and angiography revealed right ICA dissection...

BACKGROUND AND IMPORTANCE: This report illustrates a case of a low-grade glioma that showed significant disease progression during pregnancy, and then subsequent regression spontaneously in the postpartum period without treatment. This is a rare case of spontaneous glioma regression in the postpartum period, and may suggest underlying mechanisms of hormonal influences upon glioma progression. CLINICAL PRESENTATION: The patient is a 27-yr-old female who underwent placement of a right-sided ventriculoperitoneal shunt for aqueductal stenosis at 8 wk of age...

Background: Low back pain is a primary health care utilization driver in the US population. Health care evaluation visits for low back pain are as common as medical evaluation for the common cold. Low back pain is the most common reason for reductions in activities of daily living and work activity in the general population. Although these statistics are compelling, in the military population, there is arguably a significantly greater economic impact on the military population, as the cost to train, retain, and deploy a service member is a tremendous cost...
