A 23-year-old woman with a history of medically treated endocarditis presented with progressive fatigue and dyspnea on exertion.[ncbi.nlm.nih.gov]
He had been well, except for a recent infection of the upper respiratory tract, until five weeks prior to admission when he developed fatigue, dyspnea on exertion, nocturnal cough, orthopnea, paroxysmal nocturnal dyspnea, pleuritic pain of the anterior[jamanetwork.com]
Signs and symptoms of severe defects in newborns include Rapid breathing Cyanosis - a bluish tint to the skin, lips, and fingernails Fatigue Poor blood circulation Many congenital heart defects cause few or no signs and symptoms.[icdlist.com]

Our novel three-sinus enlargement technique is suitable for treating each type of SVAS and is a useful method for a baby particularly less than 10 kg without disturbing the growth of the ascending aorta.[ncbi.nlm.nih.gov]
All the patients were operated on using cardiopulmonary bypass and hypothermia. The associated anomalies were corrected simultaneously. There were no early and late deaths. Because of restenosis one child was reoperated.[ncbi.nlm.nih.gov]
One patient with diffuse stenosis that involved the ascending aorta, the aortic arch, and the descending aorta immediately at the emergence of the left subclavian artery required 35 minutes of total circulatory arrest in deep hypothermia, and there were[revespcardiol.org]
Surgery was performed with cardiopulmonary bypass (CPB), bicaval cannulation and ascending aorta, systemic and topical moderate hypothermia, aortic cross-clamping and administration of intermittent hypothermic blood cardioplegic solution every 30 minutes[scielo.br]
A 27 year-old man undergoing successful patch aortoplasty for supravalvular aortic stenosis 12 years before admission had a highfever, infectious signs in blood laboratory data, and congestive heart failure.[ncbi.nlm.nih.gov]

The main sign of heart valve disease is an unusual heartbeat sound called a heartmurmur. Your doctor can hear a heartmurmur with a stethoscope. But many people have heartmurmurs without having a problem.[icdlist.com]
A 36-year-old female was admitted to hospital exhibiting chest pain, dyspnea, and a heartmurmur on the right upper sternal border, radiating to both carotid arteries.[ncbi.nlm.nih.gov]
His heartmurmur was found at seven years of age. He was in the three percentile in both height and weight.[healio.com]
A 53-year-old man was referred to our Institution for evaluation of a systolicmurmur and congestive heart failure. He had undergone elective ascending aortic replacement one month previously due to acute type A aortic dissection.[ncbi.nlm.nih.gov]
The murmur associated with it is systolicmurmur and is similar in character to valvular aortic stenosis murmur but commonly present at 1st Intercostal space (ICS) on the right.[en.wikipedia.org]
Diagnostic methods The discovery of a systolicmurmur may prompt a cardiological examination, potentially showing ventricular hypertrophy.[orpha.net]
The chest revealed a Grade III systolicmurmur heard best at the second left intercostal space and radiated to the neck. The child was hyperactive and very friendly.[healio.com]
This is sometimes referred to as pulsusparvusettardus. There may also be a noticeable delay between the first heart sound (on auscultation) and the corresponding pulse in the carotid artery (so-called 'apical-carotid delay').[checkorphan.org]

Palpable signs include carotid and peripheral pulses that are reduced in amplitude and slow rising (pulsusparvusettardus) and an apical impulse that is sustained (thrusts with the 1st heart sound [S 1 ] and relaxes with the 2nd heart sound [S 2 ])[merckmanuals.com]
After cardiac catheterization was performed, he presented a fever and right side paresis. The echocardiogram showed multiple vegetations in the ascendant aortic arch and the supraortic arteries. The blood cultures reported S. parasanguis.[ncbi.nlm.nih.gov]
(See Workup.) The anatomic diagnosis of SVAS can reliably be made from 2-dimensional (2D) echocardiography that uses multiple views, including parasternal, apical long-axis, and suprasternal (see Workup).[emedicine.medscape.com]
A 2-year-old patient with diffuse supravalvular aortic stenosis and the Williams-Beuren syndrome at autopsy was found to have dissection of the ascending aorta in addition to severe coronary artery disease and microfocal myocardialfibrosis.[ncbi.nlm.nih.gov]
He recovered well when the blood pressure declined and the brainedema subsided. Cerebral hyperperfusion syndrome was considered, and this uncommon neurologic complication of cardiac operations is discussed.[ncbi.nlm.nih.gov]
The biventricularhypertrophy that accompanies these lesions increases myocardial oxygen consumption and compromises oxygen delivery. In addition, these patients often have direct, multifactorial compromise of coronary blood flow.[ncbi.nlm.nih.gov]
To our knowledge, the present case represents one of the longest follow-up routines in the English language literature of surgical treatment of supravalvular aortic stenosis.[ncbi.nlm.nih.gov]
Due to its rarity, surgical treatment of this clinical entity is still a matter of debate because of the variable degree of aortic narrowing, presence of multilevel obstruction, and age at presentation, all factors that strongly influence the disease prognosis[ncbi.nlm.nih.gov]
Pulmonary artery stenosis usually improves and only rarely limits prognosis. Received September 28, 1989. Revision received December 20, 1989. Accepted January 10, 1990.[content.onlinejacc.org]
This has major implications for genetic counseling, cardiac evaluation and for the prognosis of the patient and family. We evaluated 21 members of a 3-generation, 34-member family in which 12 have SVAS documented by ultrasound (US).[nature.com]
His 19-year-old sister had also been diagnosed with PPS, and his 43-year-old mother was known to have a harsh systolic cardiac murmur of unknown etiology.[ncbi.nlm.nih.gov]
Etiology SVAS is caused by a mutation in the elastin gene ( ELN ), which is located on chromosome 7q11.23. In nearly all cases, ELN mutations disrupt elastin protein synthesis, resulting in a production deficit.[orpha.net]

Complications of SVAS also include progressive coronary osteal stenosis, infective endocarditis, and sudden death. [6, 7] Etiology The precise etiology of SVAS is unknown.[emedicine.medscape.com]

Pathophysiologically, the change causes loss of elastin fibers, which are sparse and spatially disorganized.[scielo.br]
CONCLUSION: Brom aortoplasty promotes restoration of normal aortic root geometry and relief of coronary ostial stenosis, which is important in preventing myocardial ischemia. Computed tomography imaging is our preferred diagnostic modality.[ncbi.nlm.nih.gov]
This case highlights the need for heightened clinical suspicion of rare but treatable anomalies for prevention of SCD.[annalspc.com]
SVAS shows variable penetrance within families but the progressive nature of the disorder in some cases, makes identification of the molecular lesions important for future preventative treatments.[nature.com]
This is a result of the increasing calcification of the valve preventing it from "snapping" shut and producing a sharp, loud sound.[checkorphan.org]
This method is therefore believed to prevent residual aortic stenosis or future aortic restenosis owing to distortion of the reanastomotic suture line.[cardiothoracicsurgery.biomedcentral.com]
