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

ABSTRACT: Background:Sinus 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 summary:A 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. Discussion:This 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.

Project description:AimTo summarize the evidence on the clinical effectiveness and safety of coronary sinus reducing stent (CSRS) therapy in refractory angina pectoris (AP) patients.MethodsWe performed a systematic literature search in common databases (n=4). The evidence obtained was summarized according to GRADE methodology. A health technology assessment (HTA) was conducted using the HTA Core Model® for Rapid Relative Effectiveness Assessment. Primary outcomes for the clinical effectiveness domain were the proportion of patients with improvement in two or more Canadian Cardiovascular Society (CCS) angina score classes, overall mean reduction of CCS class, and Seattle Angina Questionnaire (SAQ) quality of life (QoL) score improvement. Outcomes for the safety domain were adverse device effects (ADEs) and serious adverse device effects (SADEs).ResultsOne randomized controlled trial (RCT) was identified. Outcomes that showed statistically significant differences between CSRS and sham treatment (in favor of CSRS) were CCS angina score improvement of one or two classes, overall mean reduction of CCS class, and SAQ QoL score improvement. Concerning safety, the sham-controlled trial data indicate that there were fewer SADEs in the intervention group (19%) than in the control group (46%). SADEs reported in observation studies ranged from none to 30%. The most frequently reported SADEs were death and stable angina. In the RCT, the only case of death occurred in the control group. Concerning clinical effectiveness, the risk of bias (RoB) was rated to be low, and concerning safety, the RoB was rated to range from low to moderate. As assessed by GRADE, the overall strength of evidence for effectiveness and safety was moderate. Internal and external validity of the evidence base were low.ConclusionEven though the current evidence indicates that the assessed technology, CSRS, is potentially more effective than sham intervention for refractory AP patients, the lack of internal validity of the studies undermines the partially positive results.
