Aortic Valve Replacement and Exclusion of Sinus of Valsalva Aneurysm With Balloon-Expandable Transcatheter Aortic Valve

Project description:An 85-year-old female with severe aortic valve stenosis presented with heart failure complicated with cardiogenic shock and was found to have a right coronary cusp sinus of Valsalva aneurysm. We report the first case of successful exclusion of a sinus of Valsalva aneurysm during transcatheter aortic valve replacement using a balloon-expandable valve. (Level of Difficulty: Intermediate.)

Large non-coronary sinus of Valsalva aneurysm: a case report of an unusual cause of angina pectoris.

Project description:BackgroundSinus of Valsalva aneurysm (SVA) is a rare cardiac abnormality occurring in 0.09% of the general population, but few reports have examined its recurrence. Unruptured SVAs are usually asymptomatic.Case summaryA 50-year-old woman presented with chest pain and a history of surgery for a ruptured right coronary SVA 32 years prior. Echocardiography showed the recurrence of an unruptured SVA of the non-coronary sinus with moderate aortic regurgitation, severe mitral regurgitation, and severe tricuspid regurgitation. Cardiac computed tomography (CT) revealed compression of the right coronary artery (RCA) between the SVA and sternum. Adenosine triphosphate stress myocardial perfusion imaging (MPI) identified reversible ischaemia of the inferior wall. The patient underwent patch closure of the SVA, aortic valve replacement, mitral valvuloplasty, and tricuspid annuloplasty. Post-operative MPI showed no residual ischaemia, and CT confirmed both successful repair of the SVA and intact RCA.DiscussionThis case provides two noteworthy findings. First, the SVA recurred after 32 years. Second, a non-coronary SVA causing myocardial ischaemia is extremely rare given the long anatomical distance between the non-coronary sinus and coronary arteries. In our patient, the non-coronary SVA grew large enough within the anterior mediastinum to cause RCA compression.

3D Printed Personalized External Aortic Root Model in Marfan Syndrome with Isolated Sinus of Valsalva Aneurysm Caused by a Novel Pathogenic FBN1 p.Gly1127Cys Variant.

Project description:The major cause of death in Marfan syndrome (MFS) is cardiovascular complications, particularly progressive dilatation of the proximal aorta, rendering these patients at risk of aortic dissection or fatal rupture. We report a 3D printed personalized external aortic root model for MFS with an isolated sinus of Valsalva aneurysm caused by a novel pathogenic FBN1 variant. A 67-year-old female with a history of lens dislocation and retinal detachment in the left eye was admitted for the evaluation of resting dyspnea several months prior. Transesophageal and transthoracic echocardiography revealed severe aortic valve regurgitation and a large left coronary sinus of Valsalva aneurysm in the proband. Sanger sequencing identified a heterozygous p.Gly1127Cys variant in the FBN1 gene; previously, a mutation at this amino acid position was described as pathogenic (p.Gly1127Ser; rs137854468). A 3D printed personalized external aortic root model based on a multidetector computed tomography scan was constructed to illustrate the location of the ostium of the left main coronary artery on the aneurysm of the left coronary artery cusp. Aortic root replacement with the Bentall procedure matched the exact shape of the 3D printed model. Creation of a 3D printed patient-specific model could be useful in facilitating the development of next-generation medical devices and resolving the risks of postoperative complications and aortic root disease.

Aortic valve regurgitation that resolved after a ruptured coronary sinus aneurysm was patched.

Project description:Sinus of Valsalva aneurysms appear to be rare. They occur most frequently in the right sinus of Valsalva (52%) and the noncoronary sinus (33%). More of these aneurysms originate from the right coronary cusp than from the noncoronary cusp. Surgical intervention is usually recommended when symptoms become evident. We report the case of a 34-year-old woman who presented with a congenital, ruptured sinus of Valsalva aneurysm that originated from the noncoronary cusp. Moderate aortic regurgitation was associated with this lesion. Simple, direct patch closure of the ruptured aneurysm resolved the patient's left-to-right shunt and was associated with decreased aortic regurgitation to a degree that valve replacement was not necessary. Only trace residual aortic regurgitation was evident after 3 months, and the patient remained free of symptoms after 6 months. Our observations support the idea that substantial runoff blood flow in the immediate supra-annular region can be responsible for aortic regurgitation in the absence of a notable structural defect in the aortic valve, and that restoring physiologic flow in this region and equalizing aortic-cusp closure pressure can largely or completely resolve aortic insufficiency. Accordingly, valve replacement may not be necessary in all cases of ruptured sinus of Valsalva aneurysms with associated aortic valve regurgitation.

Simultaneous transcatheter closure of ruptured sinus of Valsalva aneurysm and stent implantation for aortic coarctation.

Project description:Ruptured sinus of Valsalva aneurysm is a rare anomaly and an associated coarctation of aorta is even rarer. A combination of such defects is traditionally treated surgically. The surgery is necessarily staged and done through different approaches. We report successful simultaneous transcatheter treatment of both these defects performed in the same setting in an acutely ill adult male patient with a good intermediate-term follow-up.

A Case of Sinus of Valsalva Aneurysm Rupture in a Patient with Bicuspid Aortic Valve.

Bicuspid aortic valve with severe stenosis and ruptured sinus of Valsalva aneurysm to left ventricle.

Project description:Bicuspid aortic valve (BAV) is a common congenital cardiac anomaly, and rarely, it is associated with sinus of Valsalva aneurysms (SOVAs). And very infrequently, these SOVAs rupture into left side of heart. We hereby report a case of 12-year-old male with BAV with severe aortic stenosis with a large SOVA that ruptured into the left side of the heart. The anatomy was delineated with multimodality imaging; initially with two-dimensional trans-thoracic echocardiography (TTE), and later on with three-dimensional TTE and with multi detector computed tomography. Operative interventions were planned for the patient.
