Sinus of Valsalva aneurysm, usually a congenital anomaly, almost always ruptures into the right sided cardiac chambers, causing a left-to-right shunt with profound haemodynamic consequences. With the availability of the current genera- tion of devices and hardware, transcatheter closure has gradually replaced the surgical route. To date, most closures have been performed using an Amplatzer duct occluder (ADO). Here, we report the case of a 21 year-old male where a very large (18 mm) rupture of a sinus of Valsalva aneurysm from non-coronary cusp to right ventricle was closed by a percutaneous approach using a 20/18 mm Cocoon duct occluder (CDO; Vascular Innovations, Nonthaburi, Thailand ...

This is a report on a child who, in the first decade of life, collapsed after effort and died suddenly. There was clinical evidence of acute myocardial ischaemia. At autopsy, a rare cause was found, viz. aberrant origin of the left coronary artery from the right sinus of Valsalva, which then coursed between the aorta and main pulmonary artery. The importance of recognising this congenital coronary artery abnormality is emphasised.

N2 - Aneurysm of the sinus of Valsalva (SVA) is a rare condition of the aorta. It progrediates slowly and can be hidden for a long time, but during its development it may cause various symptoms due to compression. Rupture of the aneurysm can result in acute heart failure necessitating an urgent operative treatment. We operated on a patient with symptoms of acute heart failure, grade III-IV tricuspid insufficiency, loud systolo-diastolic murmur and an extremely high calculated right ventricular pressure. The echocardiography discovered the rupture of the non-coronary sinus of Valsalva shunting to the right ventricle. During the operation we removed the aneurysm sac, and closed the hole directly with running sutures. The involved non-coronary cusp ruptured in the early postoperative course, so an acute ...

Oxidative stress and inflammation are central mediators of atherosclerosis particularly in the context of diabetes. The potential interactions between the major producers of vascular reactive oxygen species (ROS), NADPH oxidase (NOX) enzymes and immune-inflammatory processes remain to be fully elucidated. In the present study we investigated the roles of the NADPH oxidase subunit isoforms, NOX4 and NOX1, in immune cell activation and recruitment to the aortic sinus atherosclerotic plaque in diabetic ApoE−/− mice. Plaque area analysis showed that NOX4- and NOX1-derived ROS contribute to atherosclerosis in the aortic sinus following 10 weeks of diabetes. Immunohistochemical staining of the plaques revealed that NOX4-derived ROS regulate T-cell recruitment. In addition, NOX4-deficient mice showed a reduction in activated CD4+ T-cells in the draining lymph nodes of the aortic sinus coupled with reduced pro-inflammatory gene expression in the aortic sinus. Conversely, NOX1-derived ROS appeared to ...
Echocardiography is the primary modality for imaging the aorta for the diagnosis and serial evaluation of pathological conditions. In this article, we review the methodology for optimal echocardiographic imaging of the various segments of the aorta and discuss abnormalities of the aorta including stenosis, dilation including aortopathy and sinus of Valsalva aneurysms, and fistulous communications involving the ascending aorta including aortoventricular tunnel and ruptured sinus of Valsalva aneurysm. We review novel echocardiographic measurements of aortic functional properties of the aorta such as elasticity and stiffness, and review the literature on the potential additive value of such measurements for structural assessment alone. Finally, we discuss the limitations of echocardiography in the precise and optimal imaging of the aorta.

Aneurysms of the sinus of Valsalva are infrequent anomalies caused by discontinuity between middle tunic of aorta and the valvular ring. Generally, they are asymptomatic while they are intact, most of them are diagnosed after to a rupture. They affect with more frequency males and its rupture mostly occur in young adults; this defect can be a cause of heart failure. In some cases, can occur as sudden death. Its diagnosis requires imaging studies and its treatment is usually surgical. It is presented the case of an 18 years old female patient, who consulted for symptoms of heart failure. Upon physical examination, It was found hipotension with a displaced tip shock, murmur auscultated in all auscultatory sites and it was irradiated to left armpit, presence of jugular ingurgitation and ascites.

A 67-year-old Hispanic woman who was a nonsmoker without significant past medical history was admitted for the evaluation of 3 month history of exertional angina and dyspnea. The patient reported worsening of symptoms when walking farther than 1 block or heavy lifting. She denied resting chest pain. Her resting electrocardiogram (ECG) was normal, however an office stress echocardiogram performed prior to admission was terminated after 3 min due to chest pain, shortness of breath, and 1-mm ST-segment depression. The post-exercise echocardiogram showed mild global left ventricle hypokinesis and no increase in left ventricular size. Cardiac catheterization was performed. During initial aortogram the left main coronary artery was not opacified, even after direct injection of contrast medium into the left sinus of Valsalva. However, a large collateral artery originating from the ostium of the RCA was identified on the RCA injection and subsequent selective catheterization of its orifice (Fig. 1). ...

AU - Chen, Chi Jen. AU - Mo, Yuan Heng. PY - 2007/9. Y1 - 2007/9. N2 - Anomalous coronary arteries can be benign or life threatening. Novel advances on multi-detector computed tomography (MDCT) provide a noninvasive technique and offer an accurate diagnostic modality to visualize the origin and course of anomalous coronary arteries by a 3D display of anatomy. Thus we demonstrated anomalies of coronary arteries shown by 64-MDCT in our institution. 540 subjects referred to our Hospital for MDCT coronary angiography were included in this study. These subjects were between the ages of 12 and 90 years (mean 59±12.6 years) including 297 (55%) male and 243 (45%) female. Post-processing techniques such as volume rendering (VR) and maximum intensity projection (MIP) were applied to demonstrate the coronary ...
Anomalous origination of coronary artery from the opposite sinus (ACAOS) is a rare coronary artery anomaly. Right ACAOS with interarterial course is a type of ACAOS, which conveys a high risk for myocardial ischemia or sudden death. We reported a case of right ACAOS with interarterial course in otherwise healthy young male. He was asymptomatic, until an obligatory medical check-up with treadmill test showed a sign of positive ischemic response. Further work-up revealed that he had right ACAOS with interarterial course. Watchful observation was applied to him, while strenuous physical activity and competitive sport were absolutely prohibited.
Electron beam tomography (EBT) has been widely used for the assessment of coronary calcification, particularly in patients at risk of coronary artery disease. EB angiography (EBA) has shown significant sensitivity in confirming coronary arterial narrowing involving the proximal and mid-vessel segments. The main advantage of this new imaging technique is its ability to demonstrate the arterial tree, including the coronary arteries, using single breath-hold acquisition while infusing intravenous contrast agent. It does not require a large dose of x-ray radiation exposure followed by a long recumbency for arterial healing, as does conventional coronary angiography. EBA also avoids possible claustrophobic effects of closed tube imaging used by other noninvasive techniques. We present a new application of this technique in patients with anomalous coronary arteries. In 6 patients with congenital anomalous coronary arteries, all coronary artery origins and courses were clearly demonstrated. An example ...
Pulmonary artery catheterization is associated with numerous complications, including serious arrhythmias. We report a case where ventricular tachycardia occurred repeatedly during attempted pulmonary artery catheterization, precluding successful catheterization. Transesophageal echocardiography was used to image the tricuspid valve and right ventricle and revealed a Sinus of Valsalva aneurysm protruding significantly into the right ventricle and obstructing advancement of the pulmonary artery catheter. Our case reveals another identifiable cause of serious arrhythmia during pulmonary artery catheterization and highlights how transesophageal echocardiography can be useful in unanticipated ways during cardiac anesthesia and surgery. ...

An anomalous coronary artery (ACA) is a coronary artery that has an abnormality or malformation. The malformation is congenital (present at birth) and is most often related to the origin or location of the coronary artery. However, there may be other defective areas in the coronary artery. Likewise, it may affect the overall size and shape of the affected coronary artery or arteries. ACA may also occur along with other congenital heart defects.. This condition may also be called congenital coronary artery anomaly (CAA).. Although they are present at birth, ACAs are often not diagnosed until late adolescence or adulthood, because of the lack of symptoms or because symptoms may not be recognized as being caused by ACA. Teens or adults with unknown ACA may have an initial episode of chest pain, heart failure, or even sudden cardiac death before the condition is recognized.. ...
Coronary anomalies continue to present an arcane puzzle to most cardiologists. We wish to focus on one particularly fascinating type of defect, in which both coronary arteries arise from the same aortic sinus, or an Anomalous Coronary Artery originates from the Opposite (than normal) Sinus (ACAOS). First reported in 1966 by Jokl and associates1 and more extensively discussed in 1974 by Cheitlin2 and Liberthson3 and their colleagues, anomalous origination of the left coronary artery (LCA) from the right aortic sinus is associated with a high risk of sudden death, usually related to strenuous ex... continue reading about Anomalous Coronary Artery Arising From the Opposite Sinus: Descriptive Features and Pathophysiologic Mechanisms, as Documented ...
Background: Supraventricular tachycardia (SVT) is a relatively common dysrhythmia among the general population and a common dysrhythmia presenting to the emergency department. Generally speaking, it is assumed the provider should attempt a vagal maneuver as first-line treatment for SVT, and the most common vagal maneuver used is the Valsalva. Current resources describing the method to perform the Valsalva are vague, and it seems that the exact procedure may vary across clinicians. Even though the Valsalva maneuver is accepted as first-line treatment, there may not be complete compliance with this maneuver and many emergency departments rely relatively heavily on adenosine as absolute treatment for SVT. Currently accepted methods for performing the Valsalva typically describe the patient in a sitting or semi-recumbent position prior to
Results: 78 hearts had tricuspid aortic valve and two hearts had bicuspid aortic valve. Anomalous origins of right coronary artery from the left posterior aortic sinus in one heart and the left coronary artery from the non-coronary sinus in another heart were noted. Both right and left coronary arteries arose from the anterior aortic sinus in two hearts with bicuspid aortic valve. Single right coronary ostium was seen in 63 hearts (78.75%), two right coronary ostia were found in 14 hearts (17.5%), three right coronary ostia were found in two hearts (2.5%), and four were found in one heart(1.25%). The left coronary ostium was single in all hearts. The mean diameter of right coronary ostium (RCO) was 3.17±0.87 mm and of the left coronary ostium (LCO) was 4.1±0.83 mm. The relation of the right and left coronary ostia to the sinu-tubular junction, to the bottom of the related sinus and to the commissures was also analyzed in detail ...

The pediatric heart experts at the Nemours Cardiac Center diagnose and treat children with congenital sinus of Valsalva aneurysm/aortico-left ventricular tunnel at the Nemours/Alfred I. duPont Hospital for Children in Wilmington, Del.
A 69-year-old man visited our clinic complaining of dyspnea. A chest radiograph revealed pleural effusion, and an electrocardiogram revealed complete atrioventricular block. Subsequent echocardiography showed normal left ventricular function, but marked thickening (12mm) of the wall localized to the sinus of Valsalva (Fig. 1A). Computed tomography (CT) also revealed similar findings (Fig. 1B). Blood tests revealed an elevated erythrocyte sedimentation rate, and positron emission CT showed accumulation corresponding to the thickened wall at the sinus of Valsalva (Fig. 1C). At first, we diagnosed aortic intramural hematoma and treated with aggressive blood-pressure control, but during the first several weeks of treatment the thickened wall did not decrease at all. Subsequently, the patient started to complain of severe throbbing headaches, and tenderness of the temporal region. Then, based on the diagnostic criteria of the American College of Rheumatology, temporal arteritis could be diagnosed. It ...
A 62-year-old previously asymptomatic man was attended in the emergency room for anginal chest pain of 6 hours evolution. His medical history was remarkable for a combined aortic and mitral valve replacement 15 years previously for endocarditis (anticoagulation with acenocoumarol) and an aneurysm of the noncoronary sinus and ascending aorta, treated with an end-to-end anastomosis (Dacron graft) 2 months previously.. The patient was hemodynamically stable and had persistent pain. The physical examination was not contributory and the surgical wound appeared to be healing well. The ECG showed a known left bundle branch block without changes. During the initial evaluation, echocardiography showed inferior akinesia that was not present on the postoperative study, and a normally functioning graft, without clear visualization of the ascending aorta. An onset of infarction was suspected and 250 mg of aspirin was administered. Angioplasty was contemplated, and coronary angiography performed 60min after ...

Basso et al. (17) reported an echocardiographic study of 817 apparently healthy primary school students. Bicuspid aortic valve (BAV) was found in 0.5% of cases with a higher prevalence in males (0.75% vs. 0.24%) and was significantly associated with aortic root enlargement compared with children who had tricuspid aortic valves.. Fernandes et al. (18) report on the morphology of BAV in a review of 1,135 patients ,18 years of age who were identified by echocardiography between 1986 and 1999. Median age was three years, and 67% of the patients were males. Right and left coronary leaflet fusion was the most common type occurring in 70%; AS that was moderate or greater was observed most often in patients with right coronary/noncoronary fusion. Similarly, right coronary/noncoronary fusion was more often associated with moderate or greater aortic regurgitation. The majority of patients with coarctation had fusion of right /left coronary leaflets. Prevalence of BAV in simple coarctation was 55%, complex ...
We present a case of a 17-year-old female who was referred to the pediatric cardiology clinic with a suspected diagnosis of systemic lupus erythematous. Her symptoms of sudden onset fatigue and low energy could have easily been attributed to this new diagnosis, however, a review of her medical history revealed multiple emergency room visits for chest pain and palpitations. Her physical exam was unremarkable, but her echocardiogram showed evidence of ARCAPA (figure 1). This was confirmed by cardiac computed tomography angiogram, which better delineated the diffusely dilated and tortuous coronary arteries (figure 2). While her magnetic resonance imaging revealed no evidence of prior ischemia or fibrosis, the dilated coronary arteries were consistent with coronary artery steal and collaterization. She had a successful reimplantation of the anomalous right coronary to the sinotubular junction of the aorta. The symptoms of sudden fatigue and exercise intolerance resolved, and subsequent exercise ...

I too have had episodic dizziness and general fatigue. I had a bout of generalized weakness that caused me to walk like an elderly person (Im 35). Two doctors have noted unexplained weakness in my front thighs. I have strange headaches that do not fit the migraine description. Ive been trying to figure this out actively for the past 6 months but think it actually started about 1.5 years ago. Ive had 4 MRIs, an EEG, a Sonogram and a CT Scan. I also have been sent to a Psychiatrist for evaluation. He told me that I am not depressed, not making the symtpoms up and not inducing the symptoms- yet that doesnt keep people around me from accusing me of those things anyway. The only thing that has come back are a few blood tests slightly out of range and the MRIs and CT Scan show a blockage in my right sinuses. The doctors are discussing the possibility of operating to take out the blockage, partly in hopes that that will help my symptoms some (although the ENT says he doesnt expect anything ...
Results The incidence of PP and LP, the interval between QRS and LP and the amplitude of PP and LP in IVAs group were significantly greater than those of controls (P , 0.05). In IVAs groups, the amplitude of PP at the target site was smaller than that of unsuccessful site (0.240 ± 0.249 mV vs 0.798 ± 0.532mV, P = 0.004). LP was more often recorded at the target site than at an unsuccessful ablation site before and after RF application (before, P = 0.001; after, P , 0.001). After ablation, the amplitude of LP was obviously decreased (P = 0.016) and the interval between QRS and LP was longer in 21 patients (117 ± 28 ms vs 138 ± 31 ms P = 0.026) at the target site.. ...
