Myxomatous Degeneration

Abstract OBJECTIVES Previous series of minimally invasive mitral valve repairs showed excellent results at up to 10 years of follow-up. The goal of this study was to assess the long-term durability beyond 10 years of the edge-to-edge repair for myxomatous degeneration performed through a minimally invasive approach. METHODS Ninety-seven consecutive patients (mean age 35 ± 9 years; left ventricular ejection fraction 63 ± 6%) with severe myxomatous mitral regurgitation (MR) underwent mitral valve repair through a right minithoracotomy between 1999 and 2006. MR was due to lesions involving the posterior leaflet (7.2% of patients), anterior leaflet (12.4%) and both leaflets (80.4%). RESULTS No hospital deaths occurred. At hospital discharge all patients had no or trivial MR. Follow-up was 100% complete (median 15.5 years; interquartile range 13.6–17.0, max 19.3 years). The 16-year overall survival rate was 95.9 ± 2.02% [95% confidence interval (CI) 89.39–98.43]. At 16 years, the cumulative incidence function of cardiac death, with non-cardiac death as a competing risk, was 3.1 ± 1.75 (95% CI 0.83–8.02). Only 3 patients (4.1%) had redo operations for recurrent severe MR. At 16 years, the cumulative incidence functions of reoperation for and recurrence of MR ≥3+, with death as a competing risk, were 3.1 ± 1.76% (95% CI 0.83–8.02) and 5.6 ± 2.47% (95% CI 2.06–11.83), respectively. No predictors of recurrence of MR ≥3+ were identified. At the last follow-up, moderate MR (2+/4+) was detected in 17 patients (17.5%); most of the patients were in New York Heart Association functional class I–II (97%) and in sinus rhythm (90%). CONCLUSIONS Minimally invasive mitral valve edge-to-edge repair through a right minithoracotomy for myxomatous degeneration appears to be an effective and durable approach even in the long-term follow-up (up to 19 years).

Chordal Replacement

Abstract OBJECTIVES Non-leaflet resection techniques including loop chordal replacement are being used with increasing frequency, but the long-term results of these techniques are still unknown. The aim of this study was to compare the long-term results of loop neochord replacement with leaflet resection techniques in patients undergoing minimally invasive mitral valve (MV) repair for MV prolapse. METHODS Between 1999 and 2014, 2134 consecutive MV prolapse patients underwent minimally invasive MV repair with isolated loop (n = 1751; 82.1%) or resection techniques (n = 383, 17.9%) at our institution. Follow-up data were available for 86% of patients with a mean follow-up time of 6.1 ± 4.3 years. RESULTS The 30-day mortality was 0.8% for all patients (loop: 0.7%, resection: 1.6%; P = 0.09). Leaflet resection was associated with more moderate or more mitral regurgitation on predischarge echocardiography (P = 0.003). The 1-, 5- and 10-year survival rates were 98 ± 1%, 95 ± 1% and 86 ± 2% for the loop technique versus 97 ± 1%, 92 ± 1% and 81 ± 2% for resection patients, respectively (P = 0.003). Significant predictors for late mortality were MV repair technique (P = 0.004), left ventricular ejection fraction (P < 0.001), age (P < 0.001) and myocardial infarction (P < 0.001). Freedom from MV reoperation at 1, 5 and 10 years was 98 ± 1%, 97 ± 1%, 97 ± 1% and 97 ± 1%, 97 ± 1%, 96 ± 1% for patients operated on with the loop technique and leaflet resection (P = 0.4). CONCLUSIONS In our patient cohort, MV repair with loop chordal replacement is associated with less early recurrent mitral regurgitation and very good long-term results when compared to classical leaflet resection techniques for MV prolapse and is therefore an excellent option for such patients.

Objective Granted that minimally invasive mitral valve (MV) surgery short-term results were found to be equivalent to those achieved with traditional sternotomy with respect to perioperative morbidity and echocardiographic outcomes, little is known about the long-term efficacy of this approach. This report analyzes a 10-year single-surgeon experience with minimally invasive MV surgery through a right minithoracotomy with peripheral cannulation and external aortic cross-clamping and MV repair (MVR) by direct vision. Methods We studied 179 patients (48% female) who underwent MVR between December 1999 and December 2010. Mean age was 40.2 ± 10.1 years (range, 15–67 years). One hundred seventy patients (95.0%) had degenerative diseases, and nine patients (5.0%) had endocarditic diseases. Repair techniques for degenerative disease with posterior leaflet prolapse (74 patients, 43.5%) consisted of quadrangular resection (QR) and annuloplasty (AP) combined with sliding plasty (49 patients, 58.1%); for anterior leaflet prolapse (28 patients, 16.5%) and bileaflet prolapse (66 patients, 38.8%), edge-to-edge repair (EE) and AP; in 2 patients (1.2%), annular dilatation alone consisting of AP. Repair techniques for endocarditic disease consisted of EE in six patients (66.7%), perforation closure in two patients (22.2%), and QR combined with AP in one patient (11.1%). Results All patients survived the operation and were discharged with MV regurgitation (MR) less than 2+/4+. At 10 years’ follow-up, overall survival was 98.7% ± 1.2%, freedom from redo was 98.5% ± 1.1%, freedom from MR recurrence (>2+/4+) in QR and in EE repair were, respectively, 91.7% ± 2.2% and 90.0% ± 2.4% (P = not significant). The linearized rates of overall mortality, MR recurrence (>2+/4+), and redo at follow-up are 0.10% ± 0.10% per year, 0.63% ± 0.26% per year, and 0.21% ± 0.15% per year, respectively. Conclusions Minimally invasive MVR can be performed with very good perioperative and long-term results. Freedom from MR greater than 2+/4+ recurrence for patients with QR is equivalent to that with EE repair in our patient cohort.

Abstract OBJECTIVES Previous series showed the outcomes of thoracoscopic ablation of stand-alone symptomatic paroxysmal atrial fibrillation (AF) for up to 7 years of follow-up. The goal of this study was to assess the long-term durability of surgical pulmonary vein isolation (PVI) beyond 7 years. METHODS Fifty consecutive patients {mean age 55 [standard deviation (SD): 11.2] years, previous catheter ablation in 56%, left ventricular ejection fraction 60% (SD: 4.6), left atrium volume 65 ml (SD: 17)} with stand-alone symptomatic paroxysmal AF underwent PVI through bilateral thoracoscopy ablation between 2005 and 2014. The CHA2DS2-VASc score was ≥2 in 12 patients (24%). RESULTS No hospital deaths occurred. At hospital discharge all patients but 1 (2%) were in sinus rhythm (SR). Follow-up was 100% complete [mean 8.4 years (SD: 2.3), max 15]. The 8-year cumulative incidence function of AF recurrence, with death as a competing risk, on or off class I/III antiarrhythmic drugs (AADs)/electrocardioversion/re-transcatheter ablation (TCA) was 20% (SD: 5; 95% confidence interval: 10, 32); and off class I/III AADs/electrocardioversion/re-TCA was 52% (SD: 7; 95% confidence interval: 0.83, 8.02). At 8 years, the predicted prevalence of patients in SR was 87% and 53% were off class I/III AADs/electrocardioversion/re-TCA. The recurrent arrhythmia was AF in all patients except 2, who had atypical atrial flutter (4%). No predictors of AF recurrence were identified. At the last follow-up, 76% of the patients showed European Heart Rhythm Association class I. No strokes or thromboembolic events were documented and 76% of the subjects were off anticoagulation therapy. CONCLUSIONS Despite a considerable AF recurrence rate, our single-centre, long-term outcome of surgical PVI showed encouraging data, with the majority of patients remaining in SR, although many of them were on antiarrhythmic therapy.

Introduction Since its first publication in 1997, minimally invasive video-assisted thyroidectomy (MIVAT) has developed into the predominant minimally invasive surgery of the thyroid. A major advantage over conventional thyroid surgery is the superior cosmetic result. However, there are still few data comparing the long-term cosmetic results of the two methods. This paper compares the long-term cosmetic results of the two methods, based on follow-up assessments. Methods Between 2004 and 2011, 143 preselected patients underwent a MIVAT in our department. Additionally, 134 patients underwent a conventional thyroidectomy in our hospital in 2011. A total of 117 patients from the MIVAT group and 102 patients from the conventional thyroidectomy group received follow-up assessments after 23.1 and 23.6 months, respectively, using the patient and observer scar assessment scale. Results The measurable cervical scar length averaged 1.9 cm in the MIVAT group and 3.9 cm in the conventional group (P < 0.001). Some 11.1% of the patients in the MIVAT group and 7.1% of the patients in the conventional group had developed keloid (P = 0.391). The patient scar assessment score was 10.4 for the MIVAT group compared with 9.9 for the conventional thyroidectomy group (P = 0.691) and the observer scare assessment score was 8.6 for MIVAT compared with 9.9 for conventional thyroidectomy (P = 0.011). Conclusion In the patient assessment instrument, conventional thyroidectomy had a small advantage over MIVAT in the cosmetic long-term results. This difference between the two groups was, however, not significant. Our result contradicts short-term cosmetic results of published randomized studies with improvement for MIVAT. The Observer Score demonstrates a significant advantage of the MIVAT.

Purpose: To compare long-term patency and limb survival rates for the classical in situ surgical bypass procedure versus a minimally invasive technique for femorodistal revascularization. Methods: From May 1992 to June 1994, a prospective multicenter study was undertaken at 4 centers to evaluate the open versus closed technique for femorodistal bypass grafting. Of 97 patients enrolled in the trial, 73 patients (49 men; mean age 71 years) were assigned to the long-term follow-up protocol and prospectively randomized to the open (n = 38) or closed (n = 35) procedure. The classical open technique is characterized by a long incision over the length of the bypass graft, while the minimally invasive procedure involves only two short incisions over each anastomosis site (the side branches are closed with a coaxial embolization catheter system). Graft patency was evaluated with duplex imaging periodically throughout the 4-year observation period. Results: There was no statistically significant difference between the treatment groups with respect to age, sex, hypertension, ischemic heart disease, or smoking. However, the open group had a significantly greater incidence of diabetes (p = 0.037). Over a median 4.7-year follow-up (range 0.3–6.4), 9 (12%) patients (3 open and 6 closed) were lost to follow-up: 2 died and 7 refused the duplex examination. No significant differences in 4-year patency, limb salvage, or survival was demonstrated between the open versus closed treatment groups; 4-year secondary patency was 62% versus 64%, respectively, and limb salvage was 72% versus 86%. Conclusions: The closed technique for femorodistal in situ bypass procedures yields favorable long-term outcomes compared to the traditional open technique.

Aims There is a lack of long-term data for minimally invasive acromioclavicular (AC) joint repair. Furthermore, it is not clear if good early clinical results can be maintained over time. The purpose of this study was to report long-term results of minimally invasive AC joint reconstruction (MINAR) and compare it to corresponding short-term data. Methods We assessed patients with a follow-up of at least five years after minimally invasive flip-button repair for high-grade AC joint dislocation. The clinical outcome was evaluated using the Constant score and a questionnaire. Ultrasound determined the coracoclavicular (CC) distance. Results of the current follow-up were compared to the short-term results of the same cohort. Results A total of 50 patients (three females, 47 males) were successfully followed up for a minimum of five years. The mean follow-up was 7.7 years (63 months to 132 months). The overall Constant score was 94.4 points (54 to 100) versus 97.7 points (83 to 100) for the contralateral side showing a significant difference for the operated shoulder (p = 0.013) The mean difference in the CC distance between the operated and the contralateral shoulder was 3.7 mm (0.2 to 7.8; p = 0.010). In total, 16% (n = 8) of patients showed recurrent instability. All these cases were performed within the first 16 months after introduction of this technique. A total of 84% (n = 42) of the patients were able to return to their previous occupations and sport activities. Comparison of short-term and long-term results revealed no significant difference for the Constant Score (p = 0.348) and the CC distance (p = 0.974). Conclusion The clinical outcome of MINAR is good to excellent after long-term follow-up and no significant differences were found compared to short-term results. We therefore suggest this is a reliable technique for surgical treatment of high-grade AC joint dislocation. Cite this article: Bone Joint J 2020;102-B(7):918–924.

Background and Objectives: Surgical atrial fibrillation (AF) ablation concomitant to minimally invasive mitral valve repair has been proven to offer improved short- and long-term sinus rhythm (SR) maintenance compared to mitral valve surgery only. The objective of the present study was to explore, by thorough echocardiographic assessment, long-term morphological and functional left atrial (LA) outcomes after this combined surgical procedure. Materials and Methods: From October 2006 to November 2015, 48 patients underwent minimally invasive mitral valve repair and concomitant surgical AF cryoablation. Results: After 3.8 ± 2.2 years, 30 (71.4%) of those completing the follow-up (n = 42, 87.5%) presented SR. During follow-up, four (9.5%) patients suffered from cerebrovascular accidents and two of these subjects had a long-standing persistent AF relapse and were in AF at the time of the event, while the other two were in SR. An echocardiographic study focused on LA characteristics was performed in 29 patients (69.0%). Atrial morphology and function (e.g., maximal LA volume indexed to body surface area and total LA emptying fraction derived from volumes) in patients with stable SR (60.6 ± 13.1 mL/mq and 25.1 ± 7.3%) were significantly better than in those with AF relapses (76.8 ± 16.2 mL/mq and 17.5 ± 7.4%; respectively, p = 0.008 and p = 0.015). At follow-up, patients who suffered from ischemic cerebral events had maximal LA volume indexed to body surface area 61 ± 17.8 mL/mq, with total LA emptying fraction derived from volumes 23.6 ± 13.7%; patients with strokes in SR showed very enlarged LA volume (>70 mL/mq). Conclusions: AF cryoablation concomitant with minimally invasive mitral valve repair provides a high rate of SR maintenance and this relates to improved long-term morphological and functional LA outcomes. Further prospective studies are needed to define the cut-off values determining an increase in the risk for thromboembolic complications in patients with restored stable SR.
