Percutaneous suture-mediated patent foramen ovale closure: two-year clinical follow-up.

BACKGROUND: Percutaneous suture-mediated patent foramen ovale (PFO) closure has been recently introduced in clinical practice showing a favorable efficacy and safety profile in most PFO cases. The aim of this study was to assess the long-term outcomes of PFO closure by direct suture in a large consecutive series of patients. METHODS: We extracted all consecutive patients who underwent percutaneous closure of the PFO by suture technique (HeartStitch, Fountain Valley, CA, USA) from June 2016 with a follow-up of at least 2 years. After PFO closure, patients were followed-up clinically at 1, 6 and up to 12 months and microbubble transthoracic echocardiography (TTE) scheduled between 3 and 6 months, and at 12-month follow-up. After 12 months, patients were clinically checked every 6 months. RESULTS: As of September 1, 2020, 187 patients had undergone PFO closure with suture for at least two years and, of these, 181 (121 women and 60 men, mean age 45±13 years, range 15-75 years) had complete clinical and instrumental follow-up (97%). There were no peri-procedural complications. Mean follow-up was 1076±251 days (range 727-1574). At 12-month TTE, a significant residual atrial shunt was found in 39 patients (21%). At follow-up no recurrent thromboembolic or cerebral event occurred, no instrumental evidence of suture dehiscence detected and, 18 months after the procedure, one patient had an episode of transient atrial fibrillation lasting less than 24 hours and resolved spontaneously. CONCLUSIONS: Long-term follow-up data indicate that PFO closure by direct suturing is safe and effective. Two years after the procedure, there were no significant complications, no permanent arrhythmic complications and evidence of suture dehiscence.

Giant pericardial mass case report: role of echocardiography.

Cardiac masses are rare and they are distinguished in tumors and non-tumoral masses. Primary pericardial masses are very rare and they are often asymptomatic, even if they can present with sudden cardiac death. The diagnosis of these masses is often accidental and they are generally identified with echocardiography; their characterization is usually performed by cardiac magnetic resonance imaging (MRI) but the definitive diagnosis is achieved by tissue biopsy. We described a case of primary pericardial mass in an old patient with history of hypertension, which presented at our hospital with dyspnea and low-extremity edema. The echocardiography described a giant iso/hypoechoic pericardial mass that extended on anterior, posterior and lateral walls of left ventricle and atrium, associated with pericardial effusion without hemodynamic compromise. We discovered that the mass was identified twenty years ago on a chest-computed tomography (CT). Even if we do not manage in performing a cardiac MRI, from echo characteristics we supposed that the mass was a lipoma. Lipomas are benign tumors that can develop from pericardium and they have slow growth so they can be asymptomatic for several years. Their excision is important because they may be responsible for pericardial tamponade or heart failure. Echocardiography is an economic non-invasive exam and it is helpful in differential diagnosis, treatment, follow-up and prognosis of this cardiac masses.
