Objectives: The purpose of this study is to compare the long‐term outcomes of patent foramen ovale (PFO) closure using angiography or transesophageal echocardiography as procedural guidance. Background: The interventional treatment is emerging as a safe and efficient option for patients with high likelihood of PFO‐related cryptogenic stroke and high risk of recurrence. The “gold‐standard” guidance technique remains an issue. Methods: Two cohorts of patients undergoing PFO closure for cryptogenic stroke in two catheterization laboratories of the same institution, using similar inclusion criteria but different guidance, were compared with propensity score matching. Results: A total of 374 patients were enrolled, 161 in Angio‐group and 213 in Echo‐group. No difference was detected in the procedural complication rate. In Angio‐group, radiological exposure (P = .001) and 6‐month residual shunt (16.8% vs 8.0%, P = .015) were higher. After a mean follow‐up of 41 ± 30 months, 28 patients (7.5%) presented any adverse event (death, recurrent cerebral ischemia, device‐related complications, reintervention), with a higher rate in Angio‐group (13.0% vs 3.3%, P = .001), mainly due to repeated percutaneous intervention (10.6% vs 1.4%, P = .001). The results were confirmed after propensity score matching (118 patients/group). The rate of recurrent cerebral ischemia was 1.9% and was not significantly different in the two groups. Intra‐procedural guidance and atrial septum aneurysm were independent predictors of the composite primary endpoint (OR 1.2, P = .016). Conclusions: The use of intra‐procedural transesophageal echocardiography (TEE) guidance for PFO closure allows lower residual shunt rate, radiological exposure, and adverse events, mainly driven by a significant reduction in percutaneous reintervention.

Purpose: Our study is aimed at evaluating the feasibility and reliability of a simple method for the measurement of the functional area of prosthetic aortic valves (EOA). Three-dimensional echocardiography has proven accurate for left ventricular volume, stroke volume, and aortic valve area measurement. We studied the feasibility and reliability of real time simultaneous triplane echocardiography (RT3P) for assessing the EOA with a fast formula based on the principle of continuity equation, in which we replaced Doppler-derived stroke volume (SV) with SV directly measured with RT3P. Methods and results: EOA of prosthetic aortic valves were measured in 23 consecutive patients requiring periodical follow up. EOA was calculated using Doppler continuity equation (DCE) and the RT3P method by replacing Doppler-derived SV with SV measured with real time triplane echocardiography. We compared functional areas obtained with the two methods with the prosthetic area indicated in the manufacturer's specifications and with the mean transprosthetic gradient. Both methods had a good correlation with the area indicated by the manufacturer. RT3P revealed an inverse correlation between functional area and mean gradient that was better than DCE (P = 0.0359). Inter- and intraobserver variability was not different between the two methods. Execution time was significantly shorter for RT3P. Conclusions: RT3P is a simple method that can be performed quite rapidly, and can complement the overall assessment of prosthetic valve function. Further studies can confirm our technique.

Objectives The incidence of patients with refractory angina (RA) is increasing. Medical therapy for RA is limited and prognosis is poor. Experimental data suggest that the use of Extracorporeal shockwave myocardial revascularization (ESMR) may contribute to angiogenesis and improve symptoms of angina in patients with RA. Purpose of our study is to determine the efficacy of cardiac shock wave therapy (ESMR) in the management of patients with nonrevascolarized coronary artery disease (CAD). Methods We performed a prospective cohort study to examine the efficacy of ESMR applcation in patients with RA despite optimal medical therapy, not suitable for further PCI or CABG. Characteristics such as angina class scores (CCS class score), nitroglycerin consumption and hospitalization rate among cases (patients with RA who received ESMR) and controls (patients with RA who did not receive ESMR) were compared at baseline and 6 months after ESMR therapy. In patients receiveing d ESMR the effect of on cardiac perfusion was assessed. Results There were 43 patients in the case group and 29 patients in the control group. The mean age of the patients was 70 ± 9.5 years in the case group and 71 ± 5.3 years in the control group. Other characteristics (diabetes, coronary artery bypass graft, percutaneus coronary intervention, baseline CCS class score) were similar in both groups. There was a significant improvement in CCS class score (1.33 ± 0.57 in cases and 1.92 ± 0.69 in controls; p = 0.0002), nitroglycerin consumption (20% in case cases, and 44.8% in controls; P < 0.03) and hospitalization rate significantly reduced (13.9% in case cases, and 37.9% in controls; P < 0.03). The patients who received ESMR, there was a significantly improvement in myocardial perfusion after 6 months with a 33% relative reduction of summed stress score (SSS) (p = 0.002). Conclusion This case control study demonstrates the beneficial effect of ESMR therapy on cardiac symptoms, myocardial perfusion and reduced hospitalization in patients with refractory angina. Ther current study supports a role for ESMR as a non-invasive therapuetic option for patients with RA. [ABSTRACT FROM AUTHOR]
