Giant unruptured sinus of Valsalva aneurysms causing angina pectoris.

BACKGROUND: Sinus of Valsalva aneurysm (SVA) is a rare cardiac anomaly which can be congenital or acquired. Patients with SVA are commonly asymptomatic when the occupying effect of SVA is insignificant, while ruptured SVA usually causes severe symptoms including heart failure and myocardial ischemia. CASE PRESENTATION: We present an unusual case of a 64-year-old female manifesting with exertional dyspnea as well as angina pectoris for three months. Echocardiography and cardiac computed tomographic angiography confirmed unruptured left-coronary and non-coronary SVAs. The left anterior descending artery and left circumflex artery were stretched and compressed by the SVA which causing myocardial ischemia. The patient finally received aortic root replacement (Bentall procedure) and got symptom relieved. CONCLUSIONS: Giant unruptured SVA originating from left coronary sinus is extremely rare. Our case highlights that giant SVA should be considered in cases with angina pectoris. Echocardiography and coronary computed tomographic angiography are useful and important for diagnosis. Surgery is highly recommended in patients with SVA.

Unicommissural unicuspid aortic valve (UAV) presenting as ascending aortic aneurysm with aortic dissection.

We herein present an exceptionally rare instance of a unicommissural unicuspid aortic valve (UAV) manifesting with an aneurysmal ascending aorta complicated by a type A aortic dissection .

Aorto-atrial tunnel arising from sinus of Valsalva aneurysm in a young female.

A young female patient presented with complaints of breathlessness and palpitations since 2 years. On clinical examination, there was a loud continuous murmur at the right sternal border.Transthoracic echocardiography and colour Doppler showed a tunnel-like structure originating from the aneurysmal right coronary sinus and opening into the right atrium with left to right shunt. Coronary angiography revealed a large tunnel beginning in right coronary sinus and terminating in the right atrium and right coronary artery (RCA) was seen originating from the tunnel. Cardiac catheterisation revealed normal pulmonary artery pressure. CT and 3D-reconstructed images delineated the extracardiac course of the tunnel.Various treatment modalities including percutaneous transcatheter approach and surgical treatment were taken into consideration, but because of the close proximity of RCA from the tunnel opening, surgical closure was preferred.

Right Sinus of Valsalva Aneurysm Rupturing into the Right Atrium and Dissecting into the Interventricular Septum.

The right sinus of the Valsalva aneurysm (SVA) rupturing into the right atrium (RA) and dissecting into the interventricular septum (IVS) is rare. The disease can be definitively diagnosed using two-dimensional (2D) echocardiography and color Doppler ultrasonography. Real-time biplane imaging and three-dimensional (3D) echocardiography offer new perspectives for viewing and diagnosing this disease.

Is a severe preoperative condition a contraindication for aortic valve-sparing reimplantation in type A aortic dissection?

BACKGROUND: Type A aortic dissection (TAAD) surgical management is still under debate. The purpose of this study was to demonstrate the feasibility and safety of the aortic valve-sparing root reconstruction (AVSR) procedure in 92 consecutive patients operated for TAAD, even when preoperative condition was severe (malperfusion, shock or both). METHODS: Our hospital database was reviewed to identify all patients who underwent an AVSR procedure for TAAD over 14 years. From May 2000 to June 2014, 92 consecutive patients were studied regarding to their preoperative condition. RESULTS: Age (61±13 years) and logistic Euroscore (23.4±15.3%) as well as cross-clamping (113±39 min), cardiopulmonary bypass (142±49 min) and circulatory arrest (22±13 min) times were collected. Hospital mortality was 16.3%. Mean follow-up was complete for a mean period of 27.6 months. One patient had early reoperation for aortic insufficiency. Actuarial survival at 1 year was 82.5%. The analysis of each group showed comparable mortality and morbidity in between patients. CONCLUSIONS: Based upon our experience in the management of TAAD, a reimplantation procedure could be performed regardless preoperative malperfusion or shock, with an acceptable postoperative over mortality or morbidity. A word of caution should be brought to patients over 70 years old.

Left coronary sinus of valsalva aneurysm dissecting into interventricular septum: a case report.

BACKGROUND: Sinus of Valsalva aneurysm (SVA) is an extremely rare condition, and its rupture causes acute symptoms such as chest pain and dyspnea. Ruptured SVA is frequently associated with other congenital defects. CASE PRESENTATION: A 37-year-old male presented with SVA originating from the left coronary sinus that ruptured into the interventricular septum. SVA was diagnosed by echocardiography, cardiac computed tomography and magnetic resonance imaging, and confirmed during the operation. CONCLUSIONS: SVA is a rare cardiac abnormality which can lead to severe clinical symptoms upon rupture. Immediate surgery is necessary to repair the ruptured SVA.

Surgery for Ascending Aortic Aneurysm and Aortic Valve Insufficiency in Conditions of Active Proceeding Syphilitic Aortitis and Valvulitis.

A syphilitic aortitis is a late cardiovascular lesion of tertiary syphilis that has become exceptionally rare in the antibiotic era but not eradicated completely. Syphilitic aortitis of ascending aorta complicates in ascending aortic aneurysm formation and aortic valve regurgitation, both requiring surgical treatment. After surgery, lifelong surveillance of the remainder of the aorta is recommended because of a priori supposed high incidence of delayed involvement of noninvolved aortic segments. A 3-year follow-up result of surgery of syphilitic ascending aortic aneurysm with aortic valve regurgitation in condition of active ongoing syphilitic aortitis and valvulitis is described with addressing the dimensions of remaining aortic segments. This case demonstrates that the dilatation of the remainder of the aorta does not occur during 3 years, at least when anti-syphilitic course of antibiotic is used just after operation without additional treatment during the follow-up period. A few reports on surgical treatment of syphilitic aneurysms of the ascending aorta are discussed.

Relationship between false lumen morphology and entry tear in acute type A aortic dissection.

OBJECTIVES: This study aimed to investigate the relationship between false lumen morphology and the size, aortic segment and position of the entry tear for acute type A aortic dissection. METHODS: The records of patients who underwent emergency operation for acute type A aortic dissection in our institution between April 2011 and May 2022 were examined. Data regarding size, location and position of the entry tear and preoperative computed tomography findings were reviewed. The relationship of these variables with false lumen morphology was examined and retrospectively compared according to tear size. RESULTS: Of 243 cases, characteristics of the entry tear, visualized during surgery, were confirmed in 134 cases (age = 70.9 ± 12.6 years, male = 45.5%). Tear sizes at different aortic segments were not significantly different (P = 0.376). Tears posterior to the lesser curvature were significantly smaller than those anterior to the greater curvature (P = 0.004). A thrombosed false lumen was associated with a significantly smaller tear size and position on the posterior to the lesser curvature side in aortic cross-section (all P < 0.001). Multivariate analysis showed that tear size, the presence of re-entry and tear position anterior to the greater curvature were independent predictors of a patent false lumen. CONCLUSIONS: In acute type A aortic dissection, larger tear size, the presence of re-entry and tear position anterior to the greater curvature are risk factors for a patent false lumen. Although the results of this study are valid only for patients in whom intimal tears were detected during aortic surgery, this trend may provide information for pathophysiology of the disease.

Clinical outcomes of MANTA closure device in percutaneous endovascular aortic aneurysm repair.

OBJECTIVE: The MANTA device is a plug-based vascular closure device (VCD) designed for large bore femoral arterial access site closure. It showed promising results in transcatheter aortic valve replacement cases. In this study, we report our results and evaluate the MANTA VCD in percutaneous endovascular aortic aneurysm repair (pEVAR). METHODS: All data of consecutive patients who underwent an elective pEVAR between October 2018 and December 2022 were retrospectively reviewed. In all patients at least one common femoral artery was intended to close with the MANTA VCD. Depending on the sheath size, the 14Fr or 18Fr MANTA VCD was used. On the preoperative computed tomography scan, the diameter of the common femoral artery (CFA) was measured and the amount of calcification based on the Peripheral Arterial Calcium Scoring System (PACSS) was scored. Primary outcome was procedural technical success. Procedural technical success was defined as placement of the MANTA closure device resulting in vascular closure with patent CFA, without requiring immediate open or endovascular surgery. The secondary outcomes were access site complications requiring reintervention and all-cause mortality at 30-day follow-up. RESULTS: In total, 152 consecutive patients underwent pEVAR with 291 common femoral artery closure procedures with the Manta VCD. Mean age was 74.1 ± 6.4 years, with a mean body mass index of 27.7 ± 4.4 kg/m2. The mean diameter of the CFA was 10.5 ± 1.9 mm. In 52.6% of the cases, there were no calcification on the preoperative computed tomography scan. The 18Fr and 14Fr Manta VCD were used 169 and 122 times, respectively. The technical success rate was 96.6%. Major vascular complications were reported in 4.5% of the cases, without any death-related events. CONCLUSIONS: This single-center retrospective cohort study analyzed the procedural technical success, major vascular complications and all-cause mortality at 30-day follow-up of the MANTA vascular closure device in 152 pEVAR patients with 291 common femoral artery closure procedures. The technical success rate was 96,6%. Major vascular complications were reported in 4.5% of the cases, without any death related events. We concluded that the MANTA device is a safe and feasible option with a high rate of technical success in patients undergoing pEVAR.

Congestive Heart Failure in an Adolescent With a Ruptured Sinus of Valsalva Aneurysm.

Sinus of Valsalva aneurysm (SVA) is an abnormal dilatation of the aortic root located between the aortic valve annulus and the sinotubular junction and is rare in the pediatric population. This case report describes a unique case of a 16-year-old adolescent patient admitted with progressive heart failure symptoms and diagnosed with a ruptured noncoronary SVA. He underwent surgical repair of the SVA with autologous pericardial patches and had an uncomplicated postoperative course. A genetic workup revealed an underlying 22q11.2 deletion that is infrequently associated with SVA.

Intra-stent aortic wall aneurysm formation after Be-graft covered stent implant.

Aortic wall injuries may occur after interventional treatment of aortic coarctation (CoA), especially after balloon angioplasty. We reported on a patient who presented with an intra-stent aneurysm formation after direct stenting of a native near atretic aortic CoA by using a BeGraft Aortic stent. This evidence supports the need to maintain a strict follow-up protocol. A computed tomography scan is mandatory, after covered stent implantation as well, especially in high-risk cases and even in the absence of any immediate apparent complication.

Can you accurately rule out acute aortic syndrome by restricting imaging of the aorta to the area of the patient's pain?

BACKGROUND: Acute aortic syndrome (AAS) is a life-threatening condition necessitating timely and accurate diagnosis for appropriate treatment. Currently, the only way to rule out the diagnosis is advanced imaging. The most accessible is computed tomography of the entire aorta. Most scans are negative, exposing patients to radiation, increased time in the emergency department (ED), and non-significant incidental findings. This study investigated whether restricting imaging to the area of aortic-related pain accurately rules out AAS. METHODS: A health records review was conducted on consecutive cases from three academic EDs between 2015 and 2020. Data were extracted and verified from multiple sources. Participants included adults diagnosed with AAS based on radiological evidence. The diagnostic performance of the restricted imaging strategy was assessed; sensitivity and likelihood ratios with 95% confidence intervals were calculated. RESULTS: Data from 149 cases of AAS were collected, with the majority presenting with chest pain (46%) or abdominal pain (24%). The restricted imaging strategy demonstrated a sensitivity of 96% (95% CI 91.4-98.5%) in ruling out AAS. In a subset of patients with systolic blood pressure > 90 mmHg and without aortic aneurysm/repair (n = 86), the sensitivity was 100% (95% CI 96-100%). CONCLUSION: Restricting imaging to the area of pain in hemodynamically stable patients without known aortic aneurysm provides a highly sensitive approach to ruling out AAS.

Ascending aortic aneurysm and histopathology in Alport syndrome: a case report.

BACKGROUND: Alport syndrome (AS) is caused by mutations in type IV collagen genes that typically target and compromise the integrity of basement membranes in kidney, ocular, and sensorineural cochlear tissues. Type IV and V collagens are also integral components of arterial walls, and whereas collagenopathies including AS are implicated in aortic disease, the incidence of aortic aneurysm in AS is unknown probably because of underreporting. Consequently, AS is not presently considered an independent risk factor for aortic aneurysm and more detailed case studies including histological evidence of basement membrane abnormalities are needed to determine such a possible linkage. CASE PRESENTATION: Here, we present unique histopathological findings of an ascending aortic aneurysm collected at the time of surgery from an AS patient wherein hypertension was the only other known risk factor. CONCLUSIONS: The studies reveal classical histological features of aortic aneurysm, including atheroma, lymphocytic infiltration, elastin disruption, and myxoid degeneration with probable AS association.

Surgical Management of Giant Unruptured Left Sinus of Valsalva Aneurysm With Severe Aortic Regurgitation.

Left sinus of Valsalva aneurysms are extremely rare. Concomitant aortic valve regurgitation is a comorbidity in this pathology. This case report summarizes successful surgical treatment with aortic root replacement with a modified Bentall procedure in a 49-year-old female patient who had an unruptured huge left sinus of Valsalva aneurysm with severe aortic valve regurgitation. The intraoperative assessment showed severe adhesion between the left main trunk of the coronary artery and the left sinus of Valsalva aneurysm, and meticulous adhesion detachment was required.
