Abstract
OBJECTIVES Recurrence of tricuspid regurgitation (TR) after tricuspid annuloplasty can occur in cases where a dilated right ventricle exists and subsequent leaflet tethering follows. We previously reported a new technique of the right ventricular papillary muscle approximation (RV-PMA) for functional TR associated with leaflet tethering. The objective of this study is to elucidate the mid-term outcomes and evaluate the durability of RV-PMA. METHODS Between January 2014 and March 2023, we applied RV-PMA in 20 patients of advanced functional TR with severe leaflet tethering. The indication of the technique was severe TR with leaflet tethering height >8 mm, and/or a right ventricular end-diastolic diameter >45 mm. The patients were followed up with echocardiography before discharge and at annual interval thereafter. RESULTS There was no perioperative mortality. In the echocardiography performed before discharge, TR was decreased to mild or less in 85%, and a significant improvement in right ventricular end-diastolic diameter and tethering height were achieved (53-45 mm and 11.1-4.4 mm, respectively). Furthermore, during the median 3-year follow-up period, TR was kept controlled mild or less in 80% of the cases. CONCLUSIONS RV-PMA is considered to be a safe, effective and durable technique as an additional approach for tricuspid annuloplasty.

J Cardiol 2023; 81:111-116. [PMID: 36229301 DOI: 10.1016/j.jjcc.2022.08.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Revised: 07/30/2022] [Accepted: 08/22/2022] [Indexed: 11/23/2022]
Abstract
BACKGROUND As cardiac implantable electronic devices, such as pacemakers, cardioverter defibrillators, and cardiac resynchronization therapies, have become more popular, device extraction has become more frequent. At our institution, individual treatment strategies are discussed at a heart team meeting. Transvenous lead extraction (TVLE) is a first-line treatment; however, surgical lead extraction (SLE) is sometimes selected as a primary choice to provide optimal treatment and maintain the medical safety policy. This study aimed to investigate the validity of this heart team decision-making. METHODS From 2013 to 2021, 384 consecutive patients underwent lead extraction at our institution. RESULTS SLE was proposed as the primary intervention for 21 patients who had high risk of bleeding, difficult TVLE conditions, large vegetations, and other concomitant cardiac diseases. Of the 363 TVLE patients, 10 patients required surgical intervention; 5 had TVLE difficulty followed by SLE and 5 had excessive bleeding. SLE was performed in 26 patients, 19 of whom required valve surgery, and 8 required plication of the great veins. In 4 of the 17 hybrid procedures with SLE and TVLE, excessive bleeding occurred due to laceration of the superior vena cava and innominate vein. Operative mortality was not observed in SLE patients but was observed in 1 of the 4 TVLE patients who required emergent open-chest hemostasis. CONCLUSIONS The heart team discussion was essential to provide optimal treatment and maintain medical safety policies for each patient. SLE should be selected for patients with high risk of TVLE or other cardiac complications such as tricuspid valve incompetence.

J Card Surg 2022; 37:5649-5652. [PMID: 36183397 PMCID: PMC10092609 DOI: 10.1111/jocs.16970] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2022] [Revised: 09/03/2022] [Accepted: 09/11/2022] [Indexed: 01/06/2023]
Abstract
Systemic right ventricular failure after physiologic repair for dextro-transposition of the great arteries can be managed with durable mechanical circulatory support; however, the right ventricular morphology, such as intervening papillary muscles, presents challenges to inflow cannula positioning. Papillary muscle repositioning is an innovative technique to circumvent obstructive anatomy.
