Background: Transcatheter closure of patent ductus arteriosus (PDA) has been established as a safe and effective treatment for pediatric patients. However, long-term experience in adults remains limited. Therefore, our purpose is to report our experience with this approach in Chinese adults.
Methods: Twenty-five patients (mean age, 34 years) who underwent transcatheter closure of PDA in a tertiary cardiology center in Hong Kong were recruited.
Results: The mean PDA diameter measured by angiogram was 3.1 mm (range, 1.3 6.6 mm) and the mean pulmonary-to-systemic shunt was 1.65 (range, 1.3 1.8). All procedures were performed under local anesthesia. The average procedure and fluoroscopy times were 54 14 minutes and 14 4 minutes, respectively. The mean period of hospitalization was 4 days (range, 3 5 days). Immediate, one-month and late success rates were 96%, 92% and 84%, respectively.
Conclusions: Percutaneous closure of PDA in adults is a safe and feasible procedure. It should be a reasonable alternative for adult patients who are either not fit for open-chest surgery or who prefer a less invasive approach.

Objective: The modified Fontan operation, a palliative approach for single ventricular circulation patients, often incorporates a fenestration to facilitate postoperative management. Postoperative fenestration closure is sometimes performed to mitigate potential risks such as low oxygen saturation. However, the benefits and potential risks of this procedure remain under investigation.

Systemic-to-pulmonary collaterals (SPCs) are common in congenital heart disease (CHD). Particularly in single ventricle anatomy and Fontan circulation, SPC can both complicate the postoperative course and lead to clinical deterioration in the long term. The treatment of SPC is controversial.

Over the past decade, several trials and observational studies have validated the use of minimally invasive cardiac interventions as viable treatment options for various cardiac diseases. Transcatheter techniques for severe aortic valve stenosis have rapidly emerged as alternatives to surgical aortic valve replacement in certain patient populations. Additionally, non-surgical treatment options have expanded for conditions affecting other cardiac valves, such as the mitral valve.

A 90-year-old man received a diagnosis of ascending aortic pseudoaneurysms after transcatheter aortic valve implantation (TAVI) using an Evolut PRO valve (Medtronic). Plug closure of the pseudoaneurysms was successfully performed, and the symptoms improved after the procedure. However, on postoperative day 4, the patient experienced sudden massive hemoptysis and died.
