1 Several intracardiac structures can be affected by nonpenetrating chest trauma, but serious aortic valve insufficiency due to rupture of aortic valve cusps is a rare complication. To our knowledge, the earliest published report of traumatic rupture of the aortic valve is that of Penderleath, 2 which appeared in Cited by: 9.
There are no previous reports in the literature of simultaneous injuries to both the descending aorta and the aortic valve. We report a case of a year-old man who presented with traumatic aortic regurgitation combined with traumatic pseudoaneurysm of the aortic isthmus following blunt chest trauma, and its successful repair with a hybrid Cited by: 3.
Here, we report a patient who underwent surgery for acute aortic regurgitation (AR) due to rupture of an aortic valve commissure. The patient was a 51. Aortic valve regurgitation is most common in men between the ages of 30 and However, women and those older or younger can be affected too.
Treatment of Aortic Valve Regurgitation. Treatment of aortic regurgitation depends on the degree of the regurgitation, your signs and symptoms, and whether the regurgitation is affecting your heart function. New Approaches to Aortic Disease from Valve to Abdominal Bifurcation provides a complete look at aortic valve diseases from all points of view, including etiology, physiopathology, prevention, diagnosis and treatment.
The book offers new insights into the aortic valve and pathology based on evidence of current diagnostic methods, treatments and.
Introduction. The most common cause of aortic regurgitation (AR) is calcific valve disease, and the disease course is chronic and slowly the other hand, acute or subacute course of AR is comparatively rare, and infective endocarditis, aortic dissection, and aortic valve damage caused by trauma are known : Miyako Imanaka, Masashi Amano, Chisato Izumi, Shunsuke Nishimura, Maiko Kuroda, Takeshi Harita, Sugu.

Circ J ; Case reports of traumatic aortic regurgitation caused by detached commissures are rare. We report a case of a year-old man involved in a traffic accident. During his hospitalization for subdural hematoma and pulmonary contusion, he began to suffer from heart failure.
He was operated on under diagnosis of severe aortic regurgitaion. The commissure Cited by: 5. Traumatic aortic rupture, also called traumatic aortic disruption or transection, is a condition in which the aorta, the largest artery in the body, is torn or ruptured as a result of trauma to the body.
The condition is frequently fatal due to the profuse bleeding that results from the rupture. Since the aorta branches directly from the heart to supply blood to the rest of the body, the Specialty: Emergency medicine.
This book provides comprehensive, state-of-the art insights into aortic valvuloplasty. Aortic valve repair is a relatively new procedure.
Since first being successfully performed in the s was objectively assessed in the s, this procedure has now become standardized, reproducible, and popular around the globe. Aortic regurgitation means one of your heart’s valves is leaky.
Learn what can cause it, the symptoms, and how to treat it. Traumatic aortic transection, also known as aortic rupture, is the near-complete tear through all the layers of the aorta due to trauma such as that sustained in a motor vehicle collision or a fall. This condition is most often lethal and requires immediate medical attention.
It is the second most common cause of death associated with motor. Traumatic aortic disruption is a time-sensitive injury requiring rapid and accurate diagnosis to prevent death.
Although the clinical, or mechanism, score is of primary importance in the prompt diagnosis of patients with traumatic aortic injury (TAI), the radiologic findings play a vital supportive role.
An aortic valve tear associated with aortic regurgitation following blunt chest trauma is seldom seen. In this case, a year-old man sustained a non-penetrating chest injury caused by a sudden fall from 10 meters.
This led to a sizable tear in the left coronary cusp associated with severe aortic insufficiency. The case was treated successfully by surgical Cited by: 7. This report demonstrates two cases of traumatic valvular lesions of the heart. The first is a patient with severe mitral regurgitation after a blunt chest trauma and the second a severe aortic.
Aortic regurgitation (AR) is incompetency of the aortic valve causing backflow from the aorta into the left ventricle during diastole. Causes include valvular degeneration and aortic root dilation (with or without a bicuspid valve), rheumatic fever, endocarditis, myxomatous degeneration, aortic root dissection, and connective tissue (eg, Marfan syndrome) or rheumatologic disorders.

Regurgitation is blood flow in the opposite direction from normal, as the backward flowing of blood into the heart or between heart chambers. It is the circulatory equivalent of backflow in engineered systems.
It is sometimes called reflux, as in abdominojugular reflux. Regurgitation in or near the heart is often caused by valvular insufficiency (insufficient function, with incomplete closure. Oda H.

Aortic regurgitation occurs when blood flows backwards, or retrograde, across the aortic valve from the aorta into the left ventricle during diastole. This. Aortic regurgitation occurs when the aortic valve does not close properly between heartbeats, allowing blood to regurgitate, or re-enter the left ventricle when the chamber relaxes.
Also called aortic insufficiency, mild aortic regurgitation may not cause problems, but eventually it can stretch the ventricle and affect its function.
The aorta can rupture completely or incompletely after blunt or penetrating chest trauma. Signs may include asymmetric pulses or BP, decreased blood flow to the lower extremities, and precordial systolic murmur. Diagnosis is often suspected because of the mechanism of injury and/or chest x-ray.
Keywords Valvular regurgitation †Echocardiography Recommendations Aortic valve Pulmonary valve Introduction Valvular regurgitation is increasingly prevalent and represents an important cause of cardiovascular morbidity and mortality.1 Echo-cardiography has become the primary non-invasive imaging method for the evaluation of valvular.
The etiology of aortic valve regurgitation are discussed and listed. Including causes from the leaflets, aortic root and increased afterload. Aortic regurgitation is also known as aortic. Aortic regurgitation can have many causes, including diseases that affect connective tissue, which is the substance of the aortic valve and the ascending aorta ().In most of these diseases, aortic Cited by: 4.
Aortic regurgitation is a condition that causes blood to flow backward through the aortic valve to your left ventricle. This happens because the aortic valve does not close properly. The aortic valve is between the left ventricle and the aorta. The aorta is a blood vessel that pumps blood to your body.
Paravalvular aortic regurgitation (PAR) negatively affects the prognosis after transcatheter aortic valve replacement (TAVR) with dramatically increased morbidity and mortality in patients with more than mild PAR. Because transcatheter heart valves are implanted in a sutureless fashion using oversizing to anchor the prosthesis stent frame at the level of the Cited by: Evaluation of aortic regurgitation requires consideration of valve morphology, mechanism and severity of regurgitation and assessment of aortic dilatation.
In asymptomatic patients with severe aortic regurgitation, follow-up of symptomatic status and LV size and function is mandatory.
The strongest indication for valve surgery is the presence of symptoms and/or the documentation. Traumatic aortic injury (TAI) is a life threatening condition that requires prompt diagnosis and management.
It is estimated that aortic injuries are lethal in % of cases ().With the improved in-field emergency care available today more patients survive to. Aortic regurgitation (AR) is the diastolic flow of blood from the aorta into the left ventricle (LV).
Regurgitation is due to incompetence of the aortic valve or any disturbance of the valvular apparatus (eg, leaflets, annulus of the aorta) resulting in the diastolic flow of blood into the left ventricular chamber. traumatic aortic rupture Trauma surgery A trauma-induced tear of the aorta, a common, often fatal injury due to sudden deceleration in MVAs or falls from a height Diagnosis Transesophageal echocardiography, arch aortography, CT, MRI, films.
A thoracic aortic diameter ≥ 50% larger than normal is considered an aneurysm (normal diameter varies by location). Most thoracic aortic aneurysms do not cause symptoms, although some patients have chest or back pain; other symptoms and signs are usually the result of complications (eg, dissection, compression of adjacent structures, thromboembolism, rupture).
In a South African case study, a patient presented 6 years after a penetrating chest injury with exertional dyspnoea and a continuous murmur due to aorta-right ventricular fistula complicated by aortic regurgitation.
3 The delayed presentation was explained by gradual fibrosis of the aortic valve cusp and the resultant larger : Ruchika Meel, Thumone Govindasamy, Ricardo Gonçalves. Results: Patients with significant PAR were observed to have higher frequency of HDFR, longer jet length, greater jet extent, greater circumferential extent, greater circumferential length, and greater radial length (p.
for each). On multivariable analysis, only consistent HDFR (odds ratio [OR], ; 95% confidence interval [CI], ; p ) and extent of. Aortic tears are often associated with other traumatic injuries.
The cause is usually a rapid deceleration due to high energy traumatic forces such as a Motor Vehicle Accident (MVA). Severe trauma creates a shearing force which can tear the Aorta. Relatively low impact injuries can also cause traumatic Aortic Injury especially in older patients. Designed to be of benefit to both cardiologists and radiologists, CT and MR in Cardiology covers all aspects of this fast-growing subspecialty, providing a current, comprehensive resource for physicians at the point of logists will find authoritative guidance on the performance and interpretation of CT angiography and MR to complement 5/5(1).
Document covering acute and chronic aortic diseases of the thoracic and abdominal aorta of the adult. In addition to coronary and peripheral artery diseases, aortic diseases contribute to the wide spectrum of arterial diseases: aortic aneurysms, acute aortic syndromes (AAS) including aortic dissection (AD), intramural haematoma (IMH), penetrating atherosclerotic ulcer (PAU) and.
Aortic regurgitation is a condition that causes blood to flow through the aortic valve to your left ventricle. This happens because the aortic valve does not close properly. The aortic valve is between the left ventricle and the aorta.
The aorta is a blood vessel that pumps blood to your body. The aortic valve opens and closes to direct blood. aortic regurgitation: [ re-ger″jĭ-ta´shun ] 1. a backward flowing; see also backflow and reflux.
