Fate of remnant sinuses of Valsalva in patients with bicuspid and trileaflet valves undergoing aortic valve, ascending aorta, and aortic arch replacement.

OBJECTIVE: In patients presenting with aortic valvulopathy with concomitant ascending aortic aneurysm, surgical management of the sinus of Valsalva segment remains undefined, especially for moderately dilated aortic roots. In patients with this pathology undergoing aortic valve replacement with supracoronary ascending aorta replacement, we assessed the fate of the remnant preserved sinus of Valsalva segment stratified by aortic valve morphology and pathology. METHODS: From 2002 to 2015, 428 patients underwent elective aortic valve replacement with supracoronary ascending aorta replacement. Patients were stratified on the basis of valvular morphology (bicuspid aortic valve [n = 254] and tricuspid aortic valve [n = 174]), valvular pathology (bicuspid aortic valve with aortic stenosis [n = 178], bicuspid aortic valve with aortic insufficiency [n = 76], tricuspid aortic valve with aortic stenosis [n = 61], tricuspid aortic valve with aortic insufficiency [n = 113]), and preoperative sinus of Valsalva dimensions (<40, 40-45, >45 mm). RESULTS: Kaplan-Meier analysis revealed no significant difference in freedom from reoperation in tricuspid aortic valve versus bicuspid aortic valve (P = .576). Multivariable Cox regression model performed with sinus of Valsalva dimensions at baseline and follow-up as time-varying covariates did not adversely affect survival. A repeated-measure, mixed-effects model constructed to assess longitudinal sinus of Valsalva trends revealed that the retained sinus of Valsalva dimensions remain stable over long-term follow-up (discharge to ≥10 years), irrespective of valvular morphology/pathology (bicuspid aortic valve with aortic insufficiency, tricuspid aortic valve with aortic insufficiency, tricuspid aortic valve with aortic stenosis) and preoperative sinus of Valsalva groups (<40, 40-45, >45 mm). CONCLUSIONS: In patients with nonaneurysmal sinuses of Valsalva undergoing aortic valve replacement with supracoronary ascending aorta replacement, the sinus segment can be preserved irrespective of the type of valvular pathology (aortic stenosis vs aortic insufficiency) or valvular morphology (bicuspid aortic valve vs tricuspid aortic valve). Aortic valve replacement with supracoronary ascending aorta replacement may have a stabilizing effect on the sinus segment over long-term follow-up in patients with tricuspid aortic valves or bicuspid aortic valves.

Aborted sudden cardiac death associated with an anomalous right coronary artery.

Coronary artery anomalies arising from the opposite sinus of Valsalva and having an interarterial course between the aorta (AO) and pulmonary artery (PA) are the second most common cause of sudden cardiac death among young athletes, after hypertrophic cardiomyopathy. The right coronary artery (RCA) originating from the AO above the left sinus of Valsalva (LSV) is an extremely rare anomaly. We report the first case of a RCA arising from the AO above the LSV that subsequently runs between the AO and the PA, discovered by a 64-slice multidetector coronary CT, in a patient who was successfully resuscitated from ventricular fibrillation (VF) cardiac arrest while running in a marathon race.

[Aneurysm of the ascending aorta, hyperthyroidism and pregnancy. Case report]. / Aneurisma de aorta ascendente, hipertiroidismo y embarazo. Caso clinic.

Aortic aneurysms are a rare condition in childhood and youth, etiology, evolution, natural progression and prognosis in pregnancy unknown. Hyperthyroidism occurs when there is a synthesis and/or excessive secretion of thyroid hormones during pregnancy poses difficulty for diagnosis. The new monitoring hemodynamics in pregnancy by transthoracic bioimpedance is a feasible alternative, noninvasive and real-time hemodynamic monitoring pregnant women. CASE REPORT: Primiparity 18, is referred to present tachycardia, hyperthyroidism is diagnosed and drug treatment is initiated with antithyroid from week 14.1 echocardiogram reports bivalve aortic aneurysm in the sinus of Valsalva is performed. He was determined to continue the same under strict hemodynamic and fetal monitoring. Pregnancy concludes at the end obtained through the abdomen, at 40.4 weeks, with male product, weight 2250 g, Apgar 9/9, with growth restriction type I. The mother and baby were discharged simultaneously without complications. CONCLUSSIONS: The hyperdynamic state of pregnant patients in hyperthyroidism and aneurysms is complex and potentially complicable is why the hemodynamic patient monitoring is essential to detect changes in it that endanger the life of the binomial to this condition. Heart disease and hyperthyroidism, in this case, consistent with a fetal complications level is described as intrauterine growth restriction, however narrow and multidisciplinary monitoring and timely interventions binomial lead to satisfactory results in this case.

Right sinus of Valsalva aneurysm causing extrinsic coronary compression.

Sinus of Valsalva aneurysm is a rare cardiac disorder. It is more frequently a congenital, but it may also be an acquired condition. Takayasu's disease is an extremely rare cause of this disorder. Most cases of unruptured sinus of Valsalva aneurysm are asymptomatic. Compression of the left coronary artery is an unusual manifestation of the disease that can cause angina, myocardial infarction or death. This report describes a 19-year-old black male with an unruptured right sinus of Valsalva aneurysm caused by Takayasu's disease and manifested by an acute coronary syndrome, successfully treated by surgery.

Spontaneous aortic dissection limited to sinus of Valsalva and involving the left main coronary artery.

Aortic dissection limited to one sinus of Valsalva has been described exclusively as an iatrogenic complication during catheterization interventions. This life-threatening subtype had a very small area of dissection, when coronary ostia are frequently involved. We report a 43-year-old man with dissection limited to left sinus of Valsalva, involving the left main coronary artery and causing non-ST-myocardial infarction, including severe reversible ST-depression, maximum of 9 mm in V5 lead. Dissection was suggested by cineangiography, transesophageal echocardiogram, and contrast-enhanced multidetector computed tomography. Surgical treatment was successful. There were not any associated diseases in the sinuses of Valsalsa, aortic valve or coronary arteries. Unlike previous reported cases of aortic dissection with such limited localization, the present case was spontaneous, and not iatrogenic.

Transcoronary sinus delivery of autologous bone marrow and angiogenesis in pig models with myocardial injury.

PURPOSE: The aim of the investigation is to study myocardial injury on pig model with two objectives: (1) feasibility of stimulating angiogenesis with fresh autologous bone marrow; (2) administration of the same fresh autologous bone marrow via coronary sinus with transitory occlusion. METHODS: A controlled study was done in animal model with three phases, in a study group of 12 pigs (bone marrow administration) as well as in control group of 4 pigs (saline administration). Phase 1-production of coronary stenosis and myocardial injury; Phase 2-two weeks later, administration of bone marrow through coronary sinus with 10 min occlusion in the study group and saline solution in the control group. Phase 3-two weeks later, histological staining with hematoxylin-eosin and inmunohistochemical staining with monoclonal antibody for smooth muscle alpha-actin were conducted on both study and control groups. RESULTS: The percentage of angionenesis observed in the study group was 91% and 0% in control group. Counting of positive actin in affected and control areas showed statistically significant differences in relation to both groups: study group (1.37 vs. 0.79) and control group (0.47 vs. 0.51). The percentage of mononuclear immature cells observed in the myocardium in the study group was 25% and in the control group was 0%. There was no increment in the coronary collateral circulation when comparing coronary angiography. CONCLUSIONS: Autologous bone marrow in animal model with experimental myocardial injury enhances angiogenesis, as well as vessels with smooth muscles. The transitory occlusion of the coronary sinus might be an effective way to administer cells as those from the bone marrow.

Aneurisma del seno de Valsalva con doble rotura a la arteria pulmonar y al ventrículo derecho: Reporte de un caso y revisión de la literatura / Aneurism of the Valsalva sinus with double rupture to the pulmonary artery and to the right ventricle. Report of one case and review of the literature

We report a case of a 21 year old female who presented with congestive cardiac failure. In initial investigations an aneurysm of sinus of Valsalva was found ruptured to the pulmonary artery. It was surgically repaired uneventfully. The patient was discharged home after 10 days. During the follow-up appointments she was found to have reappearing symptoms of congestive cardiac failure. This lead to her readmission and a repeated cardiac catheterization found her to have an aneurysm of sinus of Valsalva ruptured to the right ventricule, which in a second operation was succesfully repaired. We review the bibliography over the last 20 years finding tne unusual presentation of the rupture to the pulmonary artery. We point out the importance of a sharp clinical examination and the preference of cardiac catheterization to make the diagnosis
