Transcatheter closure of ruptured sinus of Valsalva: A report of first five cases in Tehran Heart Center, Iran.

Ruptured sinus of Valsalva (RSOV) is a potentially lethal lesion requiring prompt intervention. Transcatheter Closure of RSOV is a novel alternative to the standard treatment, which is open-heart surgery. In this case series, we have reported our center's first five cases of RSOV patients undergoing Transcatheter Closure.

Transcatheter closure of a ruptured sinus of valsalva: a systematic review of the literature.

Background: Ruptured sinus of Valsalva (RSOV) is a rare pathology, and current data regarding its symptoms, anatomy, associated pathologies, and appropriate therapeutic approaches are scarce. Transcatheter closure (TCC) has been performed in multiple cases; however, the information on its success rate and complications is limited. Methods: Two independent reviewers performed an advanced search based on inclusion criteria on Scopus, PubMed, and Embase from January 1985 through July 2022. The main search terms were "Sinus of Valsalva", "Rupture/Aneurysm", and "Transcatheter/Catheter/Device". Results: Totally, 1,017 relevant articles from the 3 databases were retrieved. After the final review and appraisal, 94 articles describing 407 patients who underwent the TCC of RSOV were included. Males comprised 65% of the studied patients, and the average age was 34.5 years. The total success rate of TCC was 95.6%. Forty-nine patients (12%) developed complications, the most significant of which were sustained residual shunts in 7 patients (1.7%), substantial new onset or progression of aortic insufficiency in 6 (1.5%), and RSOV recurrence in 6 (1.5%). Post-interventional mortality was reported in only 2 patients (0.5%). Conclusions: The present study is the first systematic review of available data regarding the TCC of RSOV principally comprising case series and case reports. Although TCC seems a good option, precise patient selection is mandatory.

Assessment of Left Ventricular Function and Mitral Regurgitation Severity Early After Percutaneous Device Closure of the Atrial Septal Defect.

BACKGROUND: Atrial septal defect (ASD) is one the most prevalent forms of congenital heart disease in adults. Closure of ASDs eliminates left-to-right shunt and reduces right heart volumes, but the effects of ASD closure, on the left ventricle (LV) and mitral valve competence are somewhat inconsistent. Therefore, we designed this study to evaluate the early effect of percutaneous closure of ASD on LV function and mitral regurgitation (MR) severity. METHODS: In this prospective study, we enrolled 32 patients with ASD secundum who underwent percutaneous device closure in Tehran Heart Center. We used transthoracic and transesophageal echocardiography (TEE) before the procedure and TTE 24 hours after the procedure, then compared obtained LV parameters before and after the procedure. RESULTS: LV end-diastolic diameter (LVEDD) increased significantly from 44.8 ± 2.4 to 45.8 ± 2.8 (P < 0.001). LV end-systolic diameter (LVESD) also increased but was statistically insignificant (P = 0.063) and LV ejection fraction (LVEF) remained nearly unchanged. Highest alteration was in right ventricular systolic pressure (12.4% decrease; P < 0.001) and mitral early Doppler/tissue Doppler velocity ratio (E/E') (9.7% increase; P = 0.010). The change in MR severity was insignificant using Wilcoxon signed-rank test (P = 0.157). CONCLUSIONS: We concluded that systolic functions do not change immediately. However, LVEDD and E/E' will increase immediately, resulting from the passage of all blood from the LA into the LV in the early diastole just after closure. We also observed the positive effect of device closure on reducing right ventricular systolic pressure, and at least it does not worsen MR early after the procedure.

The Malposition of the Pacing Lead in the Left Ventricle through an Atrial Septal Defect.

A 54-year-old woman with a history of unknown childhood cardiac surgery underwent dual-chamber pacemaker implantation due to an advanced atrioventricular block in our center. One week later, we were asked to further evaluate tricuspid regurgitation via transthoracic echocardiography (TTE). The postoperative TTE demonstrated a left ventricular ejection fraction of 45%, as well as moderate mitral regurgitation, a severely dilated right atrium, a moderately dilated right ventricle, a dilated main pulmonary artery (38 mm), a mildly stenotic pulmonary artery (peak gradient=30 mmHg), and moderate-to-severe tricuspid regurgitation, with a right ventricular systolic pressure of 40 mmHg. The right atrial pacemaker lead was in its proper place, the ventricular lead in the right ventricle was undetectable due to very poor TTE views. Electrocardiography (ECG) showed a pacing rhythm with no other abnormalities (Figure 1).

Takotsubo Cardiomyopathy Coexisting with Acute Pericarditis and Myocardial Bridge.

Takotsubo cardiomyopathy (TCM) is a stress-induced cardiomyopathy that occurs primarily in postmenopausal women. It mimics clinical picture of acute coronary syndrome with nonobstructive coronary arteries and a characteristic transient left (or bi-) ventricular apical ballooning at angiography. The exact pathogenesis of TCM is not well recognized. Hereby we present an unusual case of TCM that presents with signs and symptoms of acute pericarditis and was also found to have a coexisting coronary muscle bridge on coronary angiography. We discuss the impact of these associations in better understanding of the pathogenesis of TCM.
