Single arterial access closure of post-infarction ventricular septal defect: A case series.

BACKGROUND: Post-infarction ventricular septal defect (PIVSD) carries a very poor prognosis. Surgical repair offers reasonable outcomes in patients who survive the initial healing period. Percutaneous device implantation remains a potentially effective earlier alternative. METHODS AND RESULTS: From March 2018 to May 2022, 11 trans-arterial PIVSD closures were attempted in 9 patients from two centers (aged 67.2 ± 11.1 years; 77.8% male). Two patients had a second procedure. Myocardial infarction was anterior in four patients (44.5%) and inferior in five cases (55.5%). Devices were successfully implanted in all patients. There were no major immediate procedural complications. Immediate shunt grade postprocedure was significant (11.1%), minimal (77.8%), or none (11.1%). Median length of stay after the procedure was 14.8 days. Five patients (55%) survived to discharge and were followed up for a median of 605 days, during which time no additional patients died. CONCLUSION: Single arterial access for percutaneous closure of PIVSD is a good option for these extremely high-risk patients, in the era of effective large-bore arterial access closure. Mortality remains high, but patients who survive to discharge do well in the longer term.

Day-case percutaneous left atrial appendage occlusion-Safety and efficacy.

OBJECTIVES: We evaluated the safety and efficacy of percutaneous left atrial appendage (LAA) occlusion performed as a day case procedure. BACKGROUND: LAA occlusion has been shown to be safe and effective for stroke prevention in patients with atrial fibrillation. It has not been shown if the procedure can safely be performed on a day-case basis. METHODS: Retrospective analysis was made of 117 LAA occlusion procedures in a single large teaching hospital in the UK. Procedural success, procedural complications, length of stay, and readmission data were examined. RESULTS: Successful deployment of a device was possible in all but one patient (whose appendage was too large). Major in-hospital complications occurred in 1.7% of patients (both femoral vascular). Same-day discharge was made in 66% of patients overall. Since January 2016, only 3 of 59 patients (5%) have remained in hospital overnight following LAAO. Echocardiography 2-4 hr postprocedure was undertaken prior to discharge. One patient was readmitted within 7 days but this readmission would not have been prevented by overnight stay. CONCLUSIONS: LAA occlusion can be safely performed as a day case procedure with acceptable complication rates and no increment of complications related to the lack of routine overnight stay.

Occlutech percutaneous patent foramen ovale closure: Safety and efficacy registry (OPPOSE).

INTRODUCTION: Safety and efficacy data on patent foramen ovale (PFO) closure with the Occlutech Figulla Flex II device are lacking. We undertook a fully monitored prospective Registry on PFO closure using this device. METHODS: 100 patients undergoing PFO closure were enrolled into the OPPOSE Registry at 6 UK centres. The primary endpoint was PFO closure (grade 0 or 1 shunt) at 6-month BCTTE assessed by Corelab. Secondary endpoints included implantation success, complications, and atrial fibrillation during follow-up. RESULTS: 100 patients aged 43.8±11.5years, 53% male, were recruited. Indications for PFO closure included stroke (56%), TIA (29%) systemic embolism (4%) and MI (3%). Closure was undertaken under GA (44%) or LA (56%), with TOE (45%), ICE (31%), no imaging (20%) or TTE (3%). Balloon sizing was used in 98% of cases and showed a tunnel length of 7.3±3.6mm, primum-secundum separation of 7.0±2.9mm and basal inlet width of 8.5±3.5mm. Implantation was successful in all cases using 18mm (9%), 25mm (80%), 30mm (10%) and 35mm (1%) devices. 5 patients were lost to follow-up. 92 patients underwent six-month BCTTE. The primary endpoint of PFO closure (grade 0 or 1 shunt) at six months was 79.3%. One patient developed major bleeding (BARC 3b), one patient required vascular surgery, and in one patient device embolization was noted at six months and a larger device implanted. There was one case of new atrial fibrillation. CONCLUSIONS: This first prospective monitored data for the Occlutech Figulla Flex II device demonstrates good safety and efficacy data at implant and six-month follow-up.
