Ruptured sinus of Valsalva aneurysm in two patients with subarterial ventricular septal defect

Three Decades of Follow-up After Surgical Closure of Subarterial Ventricular Septal Defect

We determined the occurrence of aortic regurgitation (AR), AR progression and risk factors in patients followed up for up to three decades after closure of subarterial VSD. We reviewed the outcomes of 86 patients categorized into three groups: group I comprised 37 patients without AR and had VSD closure alone, group II comprised 40 patients with AR and had VSD closure without aortic valvoplasty, and group III comprised 9 patients with AR and required both VSD closure and aortic valvoplasty. Patients were followed up for 18.9 ± 7.3 years (median 19.5 years, range 3.5-36.6). At latest follow up, 54.7% (47/86) of patients had AR. The prevalence of progression of AR from any one grade to the next one higher was 37.2% (32/86). Freedom from AR progression was 75.6%, 52.1%, and 22.2% at 20 years of follow-up for groups I, II and III, respectively (p < 0.05). On the other hand, progression to moderate to severe AR occurred only in 4.7% (4/86). Group I and II patients were free from progression to significant AR, while only 33.3% of group III patients were free from progression on follow-up (p < 0.001). Multivariate Cox regression analysis showed that severity of preoperative AR was the significant risk factor for persistence and progression of postoperative AR after VSD closure. In conclusion, aortic regurgitation is common and may progress even after surgical repair of subarterial VSD. Severity of preoperative AR is the most significant predictor of persistence and progression of AR after surgical closure of subarterial VSD.

Rupture of the sinus of Valsalva mimicking tricuspid valve vegetation in a healthy, young male adult

A 24-year-old male patient presented with symptoms of acute progressive dyspnea and chest pain. Transthoracic echocardiography demonstrated a mobile mass-like lesion attached to the tricuspid valve, as well as a holodiastolic flow reversal in the descending and abdominal aorta, as increased retrograde flow. We also evaluated the vegetation-like lesion by transesophageal echocardiography. As a result, we were able to diagnose the rupture of the sinus of Valsalva with shunt flow between the aorta and the right heart that had manifested as sudden chest pain and acute dyspnea. The patient underwent surgical repair for this ruptured lesion. After surgery, there was no evidence of residual shunt flow. The objective of this report is to describe a rare presentation of a ruptured sinus of Valsalva and to discuss the importance of adequate diagnosis using advanced imaging modalities. <Learning objective: If the rupture of sinus of Valsalva remains untreated, prognosis could be poor. Prompt diagnosis and timely surgical correction are important, as is further evaluation by transesophageal echocardiography imaging, which could be mandatory for adequate diagnosis.>.

Anesthetic management of cesarean delivery in parturients with ruptured sinus of Valsalva aneurysm: CARE-compliant 2 case reports and literature review

RATIONALE

Ruptured sinus of Valsalva aneurysm is rare and dangerous in parturients. Few cases of ruptured SVA in pregnancy are reported, and the anesthetic management for cesarean delivery has scarcely been described.

PATIENT CONCERNS

A parturient at 37-week gestation complained of a sore throat and cough that started 3 days before admission, followed 1 day later by fever, dizziness, breathlessness, and palpitation on exertion. Case two at 36-week gestation complained of a 1-day history of bloating in the lower abdomen.

DIAGNOSES

Full term and preterm parturients with ruptured sinus of Valsalva aneurysm.

INTERVENTIONS

Cesarean deliveries were performed with incremental epidural anesthesia technique under invasive monitoring. Surgical correction of the ruptured sinus of Valsalva aneurysms and ventricular septal defect were performed uneventfully 13 days and 7 days postpartum, respectively, for the 2 cases.

OUTCOMES

No complications were observed in the intra- or postoperative period for both mothers and babies.

LESSONS

We reviewed the pertinent literature and reached the following conclusions: use of a multidisciplinary team to guide anesthetic management is helpful and necessary; and both general anesthesia and incremental epidural anesthesia can be safely used in parturients with ruptured sinus of Valsalva aneurysm.

Assessment of shunt volumes in children with ventricular septal defects:

The aim of this study was to compare the results of magnetic resonance based shunt volume measurements with the results of the invasive method by the principle of Fick. In 14 children (median age: 16.5 months) with ventricular septal defects the shunt volume was quantified by magnetic resonance flow measurements under spontaneous breathing conditions as well as with invasive angiography during one sedation. A good correlation between both methods was observed (r(2) = 0.8, p <0.0001, CI(95%) = 0.62-1.22). A tendency towards higher values in the noninvasive technique was found in the Bland-Altman plot (bias = 3.79). Magnetic resonance based shunt measurements are a reliable alternative to the invasive shunt measurement by cardiac catheterization.
