Abstract
INTRODUCTION Transvenous pacemaker implantation in patients post bidirectional Glenn anastomosis in one-and-a-half ventricle repair is usually not feasible. However, with a modified surgical technique for Glenn anastomosis and a combined interventional and electrophysiologic approach, the transvenous pacemaker was successfully implanted. FINDINGS AND CONCLUSIONS We reported a novel technique of pacemaker implantation in a 27-year-old woman, underlying Ebstein anomaly of the tricuspid valve, who developed intermittent complete atrioventricular block at 5 years after surgical repair. The patient had a tricuspid valve replacement and a novel modified bidirectional Glenn anastomosis for one-and-a-half ventricle repair. The Glenn circuit was conducted by opening a window between the posterior wall of the superior vena cava (SVC) and the anterior wall of the right pulmonary artery (RPA), combined with putting a Goretex membrane in the SVC below the SVC-RPA window without disconnecting the SVC from the right atrium. The transvenous pacemaker was implanted by perforating the Goretex membrane, then passing the leads from the axillary vein through the perforated membrane and placing them in the coronary sinus and right atrium.

Eur J Cardiothorac Surg 2023; 64:ezad344. [PMID: 37843446 DOI: 10.1093/ejcts/ezad344] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Revised: 09/25/2023] [Accepted: 10/15/2023] [Indexed: 10/17/2023] Open
Abstract
OBJECTIVES Patients undergoing surgical tricuspid valve replacement (TVR) are at high risk of atrioventricular conduction disorders. Because implanting a lead through the tricuspid bioprosthesis is discouraged, the patients who undergo TVR in our centre are usually given a prophylactic epicardial pacemaker. Our aim was to assess the benefits and risks of this strategy. METHODS Among the patients who underwent TVR with prophylactic epicardial pacemaker implantation, clinical evaluations and pacemaker reports were analysed retrospectively after surgery. The need for cardiac pacing were assessed by characterizing the atrioventricular conduction, while the risks were evaluated by listing and adjudicating post-operative events. RESULTS A total of 80 patients were analysed (mean age was 57 ± 16 years old, 30% males). TVR was isolated in 28 (35%) patients, but most often associated with another valve surgery. In the postoperative period, heart rhythm was analysed in 59/80 patients during a median follow-up of 35 months. Cardiac pacing was needed in 46% patients: 14% had complete pacing dependency, 17% had high degree AV block, while 15% had a high ventricular pacing rate (>80%). No pre- or per-operative variables could predict cardiac pacing requirement. Post-operatively, a spontaneous heart rate >70 bpm (P = 0.02) and the presence of narrow QRS (P = 0.03) were significantly associated with a lower risk of cardiac pacing requirement. Complications related to epicardial pacemaker were documented in 2 (2.5%) patients. CONCLUSIONS After TVR, cardiac pacing was needed in 46% of patients for post-operative atrioventricular conduction disorders. This high incidence associated with an acceptable safety profile supports a prophylactic epicardial pacing strategy for the patients undergoing TVR.

World J Clin Cases 2022; 10:4810-4817. [PMID: 35801058 PMCID: PMC9198848 DOI: 10.12998/wjcc.v10.i15.4810] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Revised: 02/28/2022] [Accepted: 03/26/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Thoracoscopic-assisted technology can ensure that doctors can implement minimally invasive treatment through the right intercostal incision or small incision of the lower sternum. This approach not only can achieve a cardiac correction effect equivalent to that of a thoracotomy but also has the benefit of a clear surgical field ensuring the safety of surgical treatment.
AIM To investigate the effect of thoracoscopic tricuspid valvuloplasty in patients with tricuspid valve disease.
METHODS A total of 41 patients with tricuspid valve disease underwent traditional thoracotomy treatment between January 2018 and June 2020. Forty-one patients with tricuspid valve disease who underwent thoracoscopic tricuspid valvuloplasty treatment between July 2020 and June 2021 in our hospital were selected as controls for our retrospective analysis. The study group underwent thoracoscopic tricuspid valvuloplasty, while traditional thoracotomy was performed in the control group. The operation conditions (the duration of extracorporeal circulation, aorta blocking, endotracheal intubation, and surgery), inflammatory response-related indices (C-reactive protein and white blood cell count) before and after surgery, parameters related to myocardial injury (myocardial troponin T, creatine kinase isoenzyme, creatine kinase, and lactate dehydrogenase), and the incidence of adverse events in the two groups was counted.
RESULTS The duration of extracorporeal circulation (109.35 ± 50.31 min), aortic occlusion (94.26 ± 59.61 min), endotracheal intubation (12.59 ± 3.54 h), and hospital stay (5.29 ± 2.34 d) in the study group were shorter than those in the control group (114.91 ± 46.98 min, 101.37 ± 61.44 min, 13.11 ± 4.01 h, 7.09 ± 3.11 d, respectively). The difference in hospital stay between the two groups was statistically significant (P < 0.05). Serum C-reactive protein level (4.69 ± 1.35 mg/L) and white blood cell count (6.21 ± 1.97 × 109/L) in the study group were found to be not significantly different than those in the control group (5.01 ± 1.18 mg/L, 5.98 ± 2.01 × 109/L, respectively; P > 0.05). Myocardial troponin T (0.04 ± 0.02 ng/mL), creatine kinase isoenzyme (4.02 ± 1.11 mg/mL), creatine kinase (91.35 ± 10.44 U/L), and lactate dehydrogenase (179.81 ± 60.04 U/L) in the study group were also not statistically significant different than those in the control group (0.05 ± 0.03 ng/mL, 3.97 ± 1.05 mg/mL, 89.69 ± 13.05 U/L, 186.35 ± 56.96 U/L; P > 0.05). After the operation, serum C-reactive protein level (7.89 ± 1.73 mg/L) and white blood cell count (10.76 ± 2.35 × 109/L) in the study group were significantly lower than those in the control group (9.96 ± 2.04 mg/L, 14.84 ± 3.07 × 109/L, respectively) (P < 0.05). In addition, myocardial troponin T (0.89 ± 0.32 ng/mL), creatine kinase isoenzyme (26.96 ± 4.95 mg/mL), creatine kinase (608.32 ± 202.33 U/L), and lactate dehydrogenase (282.56 ± 101.34 U/L) in the study group were lower than those in the control group (2.61 ± 0.69 ng/mL, 34.37 ± 6.87 mg/mL, 689.94 ± 214.64 U/L, 369.15 ± 114.46 U/L) (P < 0.05). The incidence of adverse events in the study group (4.88%) was lower than that in the control group (19.51%) (P < 0.05).
CONCLUSION Thoracoscopic tricuspid valvuloplasty can achieve good results in treating patients with tricuspid valve disease, reduce the risk of adverse events, and promote the rapid recovery of patients.

Atrioventricular Block Necessitating Chronic Ventricular Pacing After Tricuspid Valve Surgery in Patients With a Systemic Right Ventricle: Long-Term Follow-Up. Front Cardiovasc Med 2022; 9:870459. [PMID: 35620520 PMCID: PMC9127255 DOI: 10.3389/fcvm.2022.870459] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2022] [Accepted: 03/28/2022] [Indexed: 11/29/2022] Open
Abstract
Background Patients with transposition of the great arteries (TGA) after an atrial switch or congenitally corrected TGA (ccTGA) are prone to systemic right ventricular (sRV) failure. Tricuspid valve (TV) regurgitation aggravates sRV dysfunction. Timely TV surgery stabilizes sRV function, yet the development of atrioventricular (AV)-conduction disturbances in the course of sRV failure can contribute to sRV dysfunction through pacing-induced dyssynchrony. This study aims to explore the incidence, timing, and functional consequences of AV-block requiring ventricular pacing after TV surgery in patients with sRV. Methods Consecutive adolescent and adult patients with an sRV who underwent TV surgery between 1989 and 2020 and followed-up at our center were included in this observational cohort study. Results The data of 28 patients (53% female, 57% ccTGA, and a mean age at surgery 38 ± 13 years) were analyzed. The mean follow-up was 9.7 ± 6.8 years. Of the remaining 22 patients at the risk of developing high degree AV-block after TV surgery, 9 (41%) developed an indication for chronic ventricular pacing during follow-up, of which 5 (56%) within 24 months postoperatively (3 prior to hospital discharge). The QRS duration, a surrogate marker for dyssynchrony, was significantly higher in patients with chronic left ventricular pacing than in patients with native AV-conduction (217 ± 24 vs. 116 ± 23 ms, p = 0.000), as was the heart failure biomarker NT-pro-BNP [2,746 (1,242–6,879) vs. 495 (355–690) ng/L, p = 0.004] and the percentage of patients with ≥1 echocardiographic class of deterioration of systolic sRV function (27 vs. 83%, p = 0.001). Of the patients receiving chronic subpulmonary ventricular pacing (n = 12), 9 (75%) reached the composite endpoint of progressive heart failure [death, ventricular assist device implantation, or upgrade to cardiac resynchronization therapy (CRT)]. Only 4 (31%) patients with native AV-conduction (n = 13) reached this composite endpoint (p = 0.027). Conclusion Patients with a failing sRV who undergo TV surgery are prone to develop AV-conduction abnormalities, with 41% developing an indication for chronic ventricular pacing during 10 years of follow-up. Patients with chronic subpulmonary ventricular pacing have a significantly longer QRS complex duration, have higher levels of the heart failure biomarker NT-pro-BNP, and are at a higher risk of deterioration of systolic sRV function and progressive heart failure.

J Cardiovasc Electrophysiol 2021; 32:1103-1110. [PMID: 33566390 DOI: 10.1111/jce.14932] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Revised: 01/05/2021] [Accepted: 01/27/2021] [Indexed: 01/08/2023]
Abstract
INTRODUCTION Mitral valve surgery has developed into a strong subspecialty of cardiac surgery with operative techniques and outcomes constantly improving. The development of bradyarrhythmias after mitral valve surgery is not completely understood. METHODS We investigated a cohort of 797 patients requiring mitral valve surgery with and without concomitant procedures. Incidences and predictors of pacemaker requirement as well as survival were analyzed. RESULTS In the complete follow-up period (median follow-up time: 6.09 years [95% confidence interval [CI]: 5.94-6.22 years, maximum 8.77 years) 80 patients (10% of the complete cohort) required pacemaker implantation for bradyarrhythmia. The cumulative rate of pacemaker implantation was 6.4% at 50 days (48 patients) with most (54.2%) requiring pacing for atrioventricular block. Mitral valve replacement (odds ratio [OR]: 1.905; 95% CI: 1.206-3.536; p = .041) and tricuspid ring annuloplasty (OR: 2.348; 95% CI: 1.165-4.730, p = .017) were identified as operative risk factors of pacemaker requirement after mitral valve surgery. Insulin-dependent diabetes mellitus was also identified as a predictor of pacemaker requirement (OR: 4.665; 95% CI: 1.975-11.02; p = .001). There was no difference in survival in the paced and unpaced groups. CONCLUSIONS After mitral valve surgery, a relevant subgroup of patients requires pacemaker implantation-most for atrioventricular block. We identified mitral valve replacement and tricuspid ring annuloplasty as significant operative risk factors and insulin-dependent diabetes mellitus as a demographic risk factor. While anatomic relationships help explain the operative risk factors the role of diabetes mellitus is not completely understood.

Open Heart 2020; 7:e001227. [PMID: 32206317 PMCID: PMC7078937 DOI: 10.1136/openhrt-2019-001227] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2019] [Revised: 01/30/2020] [Accepted: 02/17/2020] [Indexed: 11/14/2022] Open
Abstract
Objectives Tricuspid valve disease is increasingly encountered, but surgery is rarely performed in isolation, in part because of a reported higher operative risk than other single-valve operations. Although guidelines recommend valve repair, there is sparse literature for the optimal surgical approach in isolated tricuspid valve disease. We performed a meta-analysis examining outcomes of isolated tricuspid valve repair versus replacement. Methods We searched Pubmed, Embase, Scopus and Cochrane from January 1980 to June 2019 for studies reporting outcomes of both isolated tricuspid valve repair and replacement, excluding congenital tricuspid aetiologies. Data were extracted and pooled using random-effects models and Review Manager 5.3 software. Results There were 811 article abstracts screened, from which 52 full-text articles reviewed and 16 studies included, totalling 6808 repairs and 8261 replacements. Mean age ranged from 36 to 68 years and females made up 24%–92% of these studies. Pooled operative mortality rates and odds ratios (95% confidence intervals) for isolated tricuspid repair and replacement surgery were 8.4% vs 9.9%, 0.80 (0.64 to 1.00). Tricuspid repair was also associated with lower in-hospital acute renal failure 12.4% vs 15.6%, 0.82 (0.72 to 0.93) and pacemaker implantation 9.4% vs 21.0%, 0.37 (0.24 to 0.58), but higher stroke rate 1.5% vs 0.9%, 1.63 (1.10 to 2.41). There were no differences in rates of prolonged ventilation, mediastinitis, return to operating room or late mortality. Conclusion Isolated tricuspid valve repair was associated with significantly reduced in-hospital mortality, renal failure and pacemaker implantation compared with replacement and is therefore recommended where feasible for isolated tricuspid valve disease, although its higher stroke rate warrants further research.
