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.

RV1+RV3 Index to Differentiate Idiopathic Ventricular Arrhythmias Arising From Right Ventricular Outflow Tract and Aortic Sinus of Valsalva: A Multicenter Study.

BACKGROUND: This study aimed to investigate the predictive value of parameters of every precordial lead and their combinations in differentiating between idiopathic ventricular arrhythmias (IVAs) from the right ventricular outflow tract and aortic sinus of Valsalva (ASV). METHODS AND RESULTS: Between March 1, 2018, and December 1, 2021, consecutive patients receiving successful ablation of right ventricular outflow tract or ASV IVAs were enrolled. The amplitude and duration of the R wave and S wave were measured in every precordial lead during IVAs. These parameters were either summed, subtracted, multiplied, or divided to create different indexes. The index with the highest area under the curve to predict ASV IVAs was developed, compared with established indexes, and validated in an independent prospective multicenter cohort. A total of 150 patients (60 men; mean age, 45.3±16.4 years) were included in the derivation cohort. The RV1+RV3 index (summed R-wave amplitude in leads V1 and V3) had the highest area under the curve (0.942) among the established indexes. An RV1+RV3 index >1.3 mV could predict ASV IVAs with a sensitivity of 95% and a specificity of 83%. Its predictive performance was maintained in the validation cohort (N=109). In patients with V3 R/S transition, an RV1+RV3 index >1.3 mV could predict ASV IVAs, with an area under the curve of 0.892, 93% sensitivity, and 75% specificity. CONCLUSIONS: The RV1+RV3 index is a simple and novel criterion that accurately differentiates between right ventricular outflow tract and ASV IVAs. Its performance outperformed established indexes, making it a valuable tool in clinical practice.

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.

Successful Percutaneous Closure of an Aorto-right Ventricular Fistula After Sutureless Aortic Valve Replacement: A Case Report.

Rupture of a sinus of valsalva aneurysm (SVA) and the development of an aorto-right ventricular fistula (ARVF) is a rare condition, associated with high morbidity and mortality rates if left untreated. Opening of the SVA rupture into the right heart chambers may result in various morbidities, such as pulmonary hypertension. We present a case of a patient who developed ARVF following sutureless aortic valve replacement, and was subsequently treated successfully via a percutaneous approach.

Intramural aortic stenting of an anomalous right coronary artery arising from the left valsalva sinus: A leap into the dark?

A 69-year-old man with unstable angina underwent coronary angiography showing no lesion in the left coronary artery and critical stenosis in the proximal right coronary artery (RCA) arising from the left sinus of Valsalva.

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.

Ruptured Sinus of Valsalva Aneurysm in a Patient with a Ventricular Septal Defect Who Dropped Out of Lifelong Medical Follow-up.

Ruptured sinus of Valsalva aneurysm (RSOVA) is a rare cardiac condition associated with high morbidity and mortality rates. We herein report a 35-year-old man with a history of ventricular septal defect (VSD). He had a history of interrupted hospital visits and presented to the emergency department with dyspnea, palpitations, and dizziness for a few days. Auscultation detected a continuous murmur. Transthoracic echocardiography followed by transesophageal echocardiography demonstrated RSOVA in the right ventricle with an aorto-right ventricular fistula. The fistula was resected, and the aneurysm was surgically repaired. The patient made a good recovery.

Anomalous origin of left main coronary artery from the right sinus of Valsalva.

BACKGROUND: Anomalous coronary arteries are rare congenital variations with cases ranging from asymptomatic to life-threatening. Given the wide variability of coronary anomalies, it is challenging to predict their clinical consequences. Here, we present the 'malignant' variant - interarterial course of the left coronary artery between the aorta and pulmonary trunk - given the highest risk of sudden cardiac death among the various coronary anomalies. CASE PRESENTATION: Our case presents a 22-year-old male presenting to the emergency department after a syncopal episode that occurred while the patient was driving a motor vehicle. Initial Computed Tomography (CT) of the chest performed as part of the trauma work-up revealed a rare case of an anomalous origin of the left main coronary artery (LMCA) originating from a common ostium with the right coronary artery (RCA). The LMCA was found to have a malignant course, as it was positioned between the aorta and pulmonary artery. Given the high risk of sudden cardiac arrest with this congenital variant, the patient underwent coronary artery bypass grafting. CONCLUSION: Anomalous coronary arteries remain the second leading cause of sudden cardiac death in young adult patients. The risk of sudden cardiac death depends on the congenital variant of the anomalous coronary artery as well as the course these vessels take. This case highlights a rare congenital variant featuring both the LMCA and RCA originating from a common ostium, with the LMCA having a malignant course, a variant with the highest risk of sudden cardiac death.

TIPS stent migration causing sinus of Valsalva rupture.

A man in his 40s presented with haematemesis and melaena and was found to have a massive variceal bleed. Endoscopic procedures were ineffective at controlling the bleed; thus, an emergent transjugular intrahepatic portosystemic shunt (TIPS) procedure was performed. There were no noted complications from the procedure and the patient was eventually discharged home. A month later, a murmur was auscultated on routine physical examination. This prompted an outpatient transthoracic echocardiogram which revealed a TIPS stent in the inferior vena cava (IVC) extending into the right atrium along with a ruptured sinus of Valsalva with left to right shunt.The patient declined surgical intervention. He is currently being followed in the outpatient setting with serial echocardiograms and medical management.

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.

Lead I R-wave indexes: A novel electrocardiographic criterion for distinguishing the origin of idiopathic premature ventricular contractions from the three subregions of the aortic sinus cusps.

PURPOSE: The current study was conducted to investigate the electrocardiographic (ECG) characteristics of idiopathic premature ventricular contractions (PVCs) originating from the aortic sinus cusp (ASC) and establish a novel ECG criterion to discriminate PVCs originating from the right coronary cusp (RCC), left coronary cusp (LCC), and the left and right coronary cusp junction (LRJ). METHODS: A retrospective analysis was performed on a total of 133 patients with idiopathic PVCs who underwent successful mapping and ablation. The sites of origin (SOO) were confirmed using fluoroscopy and a three-dimensional mapping system during radiofrequency catheter ablation (RFCA). Among the patients, 69 had PVCs originating from the LCC, 39 from the RCC, and 25 from the LRJ. Characteristics of surface 12­lead electrocardiograms (ECGs) recorded during PVCs were analyzed. Q-, R-, S, and R'-wave amplitudes were measured in lead I, and the lead I R-wave indexes (IRa, IRb, IRc, IRd, and IRe) were derived by employing multiplication, subtraction, sum, and division operations on these ECG measurements. Notably, IRb and IRe demonstrated usefulness as ECG indexes for discriminating PVCs originating from RCC, LCC, and LRJ in the ASC. RESULTS: The R- and S-wave amplitudes in lead I exhibited statistically significant differences among the three groups (P < 0.001 and P < 0.001, respectively). In discriminating PVCs originating from the RCC from the other two groups, IRb showed the largest area under the curve (AUC) of 0.813, as assessed by receiver operating characteristic (ROC) analysis, with a cutoff value of ≤0.5 indicating PVCs of RCC origin. The sensitivity and specificity were 80.3% and 78.7%, respectively. For discriminating PVCs arising from the LCC from those in the LRJ group, IRe exhibited the largest AUC of 0.801, with an optimal cutoff value of 0. An IRe value >0 indicated PVCs originating from the LRJ, while an IRe value ≤0 indicated PVCs originating from the LCC. The sensitivity and specificity of the IRe index were 84.0% and 70.7%, respectively. CONCLUSION: Lead I R-wave indexes provided simple and useful ECG criteria for discriminating PVCs originating from the LCC, RCC, and LRJ in the left ventricular outflow tract (LVOT).

Interventricular septal dissecting aneurysm resulting from congenital coronary fistula: A case report.

Dissected interventricular septal aneurysm is a rare complication that occurs in conditions such as acute myocardial infarction, sinus valsalva aneurysm, infective endocarditis, thoracic trauma, pericardiocentesis and balloon angioplasty. Only two cases of dissected interventricular septal aneurysm secondary to coronary fistula have been described in the literature. Here, we present a case of dissected interventricular septal aneurysm secondary to congenital coronary fistula.

Aortic sinus aneurysm invading ventricular septum and dissection caused by Behcet's disease: a case report and literature review.

Few case reports have mentioned the aortic sinus aneurysm invading ventricular septum and dissection caused by Behcet's disease. Here, we reported a 36-year-old male patient with an aortic sinus aneurysm invading the ventricular septum and dissection caused by Behcet's disease, who manifested as recurrent chest tightness and shortness of breath. Cardiac ultrasound showed the rupture of the right aortic sinus and the formation of ventricular septal dissection. Ascending aortic valve prosthesis replacement, mitral valvuloplasty with ring implantation and tricuspid valvuloplasty were performed. Postoperatively, he was treated with hormones, hydroxychloroquine sulfate, mycophenolate mofetil tablets, thalidomide and warfarin, and his symptoms were relieved. This is a rare case easily being misdiagnosed and missed, early diagnosis and in-time treatment are crucial to avoid surgical complications. The diagnostic and therapeutic approaches of this patient were reported and related literature was reviewed in this case report.

Complicated catheter ablation of premature ventricular contractions from the left sinus of Valsalva in a young female. Case presentation.

Idiopathic premature ventricular complexes (PVCs) are usually benign and are often treated conservatively. Data regarding radiofrequency catheter ablation (RFA) of PVCs from the aortic sinus of Valsalva are spare. Furthermore, there are limited data regarding complications and their solutions during RFA of PVCs from the aortic sinus of Valsalva. Here we describe a clinical case of symptomatic PVCs in a 27yrold young woman with reduced exercise tolerance and dyspnea. The patient had taken anti-arrhythmic group Ic, II, and III drugs with no significant effect. Successful catheter ablation of PVCs from the left sinus of Valsalva was complicated by acute occlusion of the left main coronary artery (LCA) followed by polymorphic ventricular tachycardia and ventricular fibrillation. Cardioversion and intravenous antiarrhythmic administration restored the sinus rhythm. The LCA was stented with a bioresorbable Magmaris stent with the support of extracorporeal membrane oxygenation that was required due to severe hypotension and ineffectiveness of vasopressors. After the procedure, a favorable angiographic effect was noted. The result of stenting was monitored with IVUS intravascular navigation. The patient was discharged in a satisfactory condition on the 10th day after the procedure. Special attention should be applied to prevent complications and to careful patient selection for RFA in the left sinus of Valsalva, and care must be taken to avoid injury to the LCA. Timely and correct procedures can result in patient survival even after acute LCA injury and occlusion.

Complete heart block caused by sinus of valsalva pseudoaneurysm-A rare case.

Acquired pseudoaneurysms of the aortic root involving the sinus of Valsalva (SOV) are rare and serious complications arising from trauma, infection, or following cardiac surgery or intervention. Complete heart block (CHB) is an atypical presentation of SOV pseudoaneurysm due to either direct compression effects or involvement of the main conducting system by blood and inflammatory cell infiltration. Herein, we describe a rare case of a patient who presented with CHB caused by an SOV pseudoaneurysm following polytrauma and was treated with surgical closure of pseudoaneurysm followed by implantation of a permanent pacemaker to treat the persistent CHB.
