“…Transcatheter closure of PVL has emerged as a promising alternative with low complication rates and high clinical success [23]. Compared with surgical closure of PVL, lower mortality rates have been documented in patients treated with transcatheter closure [23]. Smolka et al reported transcatheter PVL closure in 49 patients, 29 in the mitral position and 20 in the aortic position.…”

Background: KONAR-MFO (multifunctional occluder) [Lifetech, Shenzhen, China] was first used in humans in 2013 and received the CE mark in May 2018.As name suggest, it can be use in various(multifunctional) situations in pediatric as well as adults. This is a versatile device with an improved delivery and flexibility which make this device a better option to be use with more comfort and minimum complications. In this paper, this paper is regarding few rare and complicated lesions, like anomalous origin of coronary artery from pulmonary artery (ALCAPA) device closure, device closure of ventricular septal rupture (VSR) post myocardial infarction in sick elderly and finally device closure of paravalvar leak (PVL)after mitral valve replacement which were treated with this device with excellent results. Methods: This study is a retrospective review from a tertiary level dedicated cardiac referral center in south India. Four cases we are reporting here in which Konar-multifunctional occluders were used in locations other than commoner and regular defects like patent ductus arteriosus, ventricular septal defect etc, over the span of one year between April 2022 and March 2023. Pre-procedure, all patients underwent detailed clinical evaluation followed by transthoracic echocardiography, 12-lead electrocardiogram, and Chest X-ray at the outpatient department. All patients were either symptomatic or had a hemodynamically significant lesion on echocardiography. The decision for transcatheter management was taken after discussing with surgical team in view of either high risk surgery or refusal from patients for surgical options. All patients were followed up post procedure at regular intervals with transthoracic echocardiograms and 12-lead electrocardiograms for a minimum period of 6 months. Results: All these three cases mentioned in our study underwent a complete closure of their respective lesions with no evidence of residual shunt. None of these patients had any major complications, prolonged stay, or any vascular injuries. All patients completed minimum 6-month follow-up and were doing well without any residual flows. First case of ALCAPA, after procedure showed improvement in IVCD, QTc duration and also no significant ischemic changes were noted. Myocardial perfusion scintigraphy was done after 6 months of procedure which showed improvement in contractile function and perfusion of left ventricle. Second case of VSR device closure patient showed immediate significant symptomatic improvement. He was transferred to the coronary care unit, and discharged seven days later. As of now the patient is alive and feeling well with no residual shunt detected by transthoracic echocardiography. No procedure -related complications have been recorded during last two years. Third case of PVL device closure had uneventful recovery from anaesthesia. Prosthetic valve functioned normally during the 5 days of post-procedure hospitalization. The transthoracic 2D- echocardiography performed during follow-up at the end of one month showed no mitral PVL.During follow-up after 1 year, the patient improved symptomatically. Normal prosthetic valve function and no leakage documented on transthoracic echocardiography Conclusions: Konar-MFO emerging as an important occluder with interesting attributes which makes it a very useful asset to have in catheterizations laboratory.

“…Available clinical results for PVL closure are promising, with low complication rates and high technical or clinical success rates (60% to 90%) (5) . Compared with surgical closure of PVL, lower mortality rates (30-day mortality rate 4.6%) have been documented in patients treated with transcatheter closure (5) . Smolka et al (6) .…”

This report describes a case of paravalvular leak (PVL) closure 20 days after surgery that was complicated by an embolized 10-mm device in a patient who underwent redo PVL closure after 6 months. Waiting for 3 months postoperatively to close a PVL is recommended. If earlier leak closure is mandatory, accepting a suboptimal result with a moderate residual leak is advised. ( Level of Difficulty: Intermediate. )
