Device closure of diverse layout of multi-hole secundum atrial septal defect: different techniques and long-term follow-up.

Background: There are no unanimous reports on different layouts and classifications of multi-hole secundum atrial septal defects (MHASD) and subsequent standardized occlusion techniques. The MHASD can be isolated or cribriform with variable inter-defects distance. In this retrospective study, experience-based classification and two approaches-based occlusion results are presented.

Peratrial Device Closure of Different Locations of Mitral Paravalvular Leaks.

Background: The current approaches of transcatheter closure of mitral paravalvular leak (MPVL) have different drawbacks. The challenges come from transseptal puncture, accessing the MPVL site, and the absence of dedicated delivery systems. This study introduces a novel peratrial approach for device closure of different locations of MPVLs using a probe-assisted delivery system under three-dimensional transesophageal echocardiography.

Surgical repair of sinus of Valsalva aneurysm in Asian patients.

Background: Sinus of Valsalva aneurysm is a rare cardiac anomaly, and the difference between Asian and Western countries in its occurrence is not well established. This study was designed to investigate the difference between Asian and Western patients.

Methods: Between September 1988 and February 2006, 83 patients with sinus of Valsalva aneurysm underwent surgical repair in our institute.
