On-table extubation is associated with reduced intensive care unit stay and hospitalization after trans-axillary minimally invasive mitral valve surgery.

OBJECTIVES: Few data are available regarding early extubation after mitral valve surgery. We sought to assess the impact of an enhanced recovery after surgery-based protocol-ultra-fast-track protocol-in patients undergoing minimally invasive transaxillary mitral valve surgery. METHODS: Data of patients who underwent transaxillary mitral valve surgery associated with ultra-fast-track protocol between 2018 and 2023 were reviewed. We compared preoperative, intraoperative and postoperative data of patients who had fast-track extubation (≤6 h since the end of the procedure) and non-fast-track extubation (>6 h) and, within the fast-track group, patients who underwent on-table extubation and patients who were extubated in intensive care unit within 6 h. Multivariable logistic regression was used to study the association of extubation timing and intensive care unit stay, postoperative stay and discharge home. RESULTS: Three hundred fifty-six patients were included in the study. Two hundred eighty-two patients underwent fast-track extubation (79%) and 160 were extubated on table (45%). We found no difference in terms of mortality and occurrence of major complications (overall mortality and cerebral stroke 0.3%) according to the extubation timing. Fast-track extubation was associated with shorter intensive care unit stay, discharge home and discharge home within postoperative day 7 when compared to non-fast-track extubation. Within the fast-track group, on-table extubation was associated with intensive care unit stay ≤1 day and discharge home within postoperative day 7. CONCLUSIONS: Fast-track extubation was achievable in most of the patients undergoing transaxillary minimally invasive mitral valve surgery and was associated with higher rates of day 1 intensive care unit discharge and discharge home. On-table extubation was associated with further reduced intensive care unit stay and hospitalization.

Improved Early Outcomes in Women Undergoing Aortic Valve Interventions.

Surgical aortic valve replacement (SAVR) in female patients has been associated with higher mortality (up to 3.3-8.9%) and postoperative complication rates when compared with their male counterparts. In recent years, TAVI has been shown to provide a greater benefit than SAVR in women. We sought to assess the early outcomes of the contemporary aortic valve intervention practice (surgical and transcatheter) in patients referred to our cardiac surgery unit. The data of consecutive patients who underwent isolated aortic valve intervention for aortic valve stenosis during the 2018-2022 period were retrieved from our internal database. Several preoperative, intraoperative, and postoperative variables were analyzed, including the predicted risk of a prosthesis-patient mismatch. Nine hundred and fifty-five consecutive patients-514 women and 441 men-were included. Among them, 480 patients-276 female and 204 male-received a transcatheter procedure, and 475-238 women and 237 men-had conventional SAVR. The women were older and had higher EuroSCORE II, while the male patients presented a higher incidence of cardiovascular comorbidities. There was no difference in mortality or major postoperative complication rates after either the surgical or transcatheter procedures between the female and male populations. The availability and targeted use of different techniques and technologies have enabled the safe and effective treatment of female patients treated for severe symptomatic aortic valve stenosis with similar results when compared with their male counterparts.

Minimally Invasive Trans-Axillary versus Full Sternotomy Mitral Valve Repair: A Propensity Score-Matched Analysis on Mid-Term Outcomes.

Background and Objectives: Minimally invasive cardiac surgery is an established approach for the treatment of heart valve pathologies and is associated with excellent technical and early postoperative outcomes. Data from medium- and long-term longitudinal evaluation of patients who underwent mitral valve repair (MVr) through transaxillary approach (TAxA) are still lacking. The aim of this study is to investigate mid-term results in patients who underwent TAxA MVr. Materials and Methods: Prospectively collected data of patients who underwent first-time MVr for MV regurgitation between 2017 and 2022, were reviewed. A total of 308 patients received TAxA, while in 220 cases, traditional full sternotomy (FS) was performed. Concomitant aortic and coronary artery bypass grafting (CABG) procedures, infective endocarditis or urgent operations were excluded. A propensity match (PS) analysis was used to overcome preoperative differences between the populations. Follow-up data were retrieved from outpatients' clinic, telephone calls and municipal administration records. Results: After PS-matching, two well-balanced cohorts of 171 patients were analysed. The overall 30-day mortality rate was 0.6% in both cohorts. No statistical difference in postoperative complications was reported. TAxA cohort experienced earlier postoperative extubation (p < 0.001) with a higher rate of extubation performed in the operating theatre (p < 0.001), shorter intensive care unit (ICU) stay (p < 0.001), and reduced hospitalization with 51% of patients discharged home (p < 0.001). Estimated survival at 5 years was 98.8% in TAxA vs. 93.6% in FS cohort (Log rank p = 0.15). The cumulative incidence of reoperation was 2.6% and 4.4% at 5 years, respectively, in TAxA and FS cohorts (Gray test p = 0.49). Conclusions: TAxA approach for MVr was associated with low rates of in-hospital mortality and major postoperative complications being furthermore associated with shorter mechanical ventilation time, shorter ICU stay and reduced hospitalization with a higher rate of patients able to be discharged home. At mid-term, TAxA was associated with excellent survival and low rate of MV reoperation.

Minimally invasive approach: is this the future of aortic surgery?

Median sternotomy incision has shown to be a safe and efficacious approach in patients who require thoracic aortic interventions and still represents the gold-standard access. Nevertheless, over the last decade, less invasive techniques have gained wider clinical application in cardiac surgery becoming the first-choice approach to treat heart valve diseases, in experienced centers. The popularization of less invasive techniques coupled with an increased patient demand for less invasive therapies has motivated aortic surgeons to apply minimally invasive approaches to more challenging procedures, such as aortic root replacement and arch repair. However, technical demands and the paucity of available clinical data have still limited the widespread adoption of minimally invasive thoracic aortic interventions. This review aimed to assess and comment on the surgical techniques and the current evidence on mini thoracic aortic surgery.

Conduction disorders after aortic valve replacement: what is the real impact of sutureless and rapid deployment valves?

BACKGROUND: Although sutureless and rapid deployment aortic valve replacement (SURD-AVR) has been associated with an increased rate of permanent pacemaker (PPM) implantation compared to conventional AVR (c-AVR), the predictors of new conduction abnormalities remain to be clarified. This study aimed to identify risk factors for conduction disorders in patients undergoing AVR surgery. METHODS: Data from 243 patients receiving minimally invasive AVR were prospectively collected. SURD-AVR was performed in 103 (42.4%) patients and c-AVR in 140 (57.6%). The primary endpoint was the occurrence of new-onset conduction disorders, defined as first degree atrioventricular (AV) block, advanced AV block requiring PPM implantation, left anterior fascicular block (LAFB), left bundle branch block (LBBB) and right bundle branch block (RBBB). RESULTS: The unadjusted comparison revealed that SURD-AVR was associated with a higher rate of advanced AV block requiring PPM when compared with c-AVR (10.5% vs. 2.1%, P=0.01). After adjusting for other measured covariates (OR: 1.6, P=0.58) and for the estimated propensity of SURD-AVR (OR: 5.1, P=0.1), no significant relationship between type of AVR and PPM implantation emerged. On multivariable analysis, preoperative first-degree AV block (OR: 6.9, P=0.04) and RBBB (OR: 6.9, P=0.03) were independent risk factors for PPM. Subgroup analysis of patients with normal preoperative conduction revealed similar incidence of PPM between SURD-AVR and c-AVR (1.3% vs. 1.9%, P=0.6). When compared with c-AVR, SURD-AVR was associated with a greater incidence of postoperative new onset LBBB (18.1% vs. 3.2%, P<0.001). This finding was confirmed after adjusting for the estimated propensity of SURD-AVR (OR: 6.3, P=0.009). CONCLUSIONS: Our study revealed that the risk of PPM implantation in patients receiving surgical AVR is heavily influenced by the presence of pre-existing conduction disturbances rather than the type of valve prosthesis. Conversely, SURD-AVR emerged as an independent predictor for LBBB and was associated with an increased risk of PPM in patients presenting with RBBB.

Right ventricular assessment can improve prognostic value of Euroscore II.

BACKGROUND: The aim of this multicenter prospective study was to evaluate the prognostic weight of preoperative right ventricular assessment on early mortality in cardiac surgery. METHODS: This is a multicenter prospective observational study performed by the Italian Group of Research for Outcome in Cardiac Surgery (GIROC) including 11 centers. From October 2017 to March 2019, out of 923 patients undergoing cardiac surgery, 28 patients with some missing data were excluded and 895 patients were enrolled in the study right ventricular dilatation was defined as a basal end-diastolic diameter >42 mm. The right ventricle (RV) function was assessed using the combination of three parameters: fractional area changing (FAC), tricuspid annular plane systolic excursion (TAPSE), and S'-wave using tissue Doppler imaging (TDI-S'); RV dysfunction was defined as the presence of at least two of the following cutoffs: FAC <35%, TAPSE <17 mm, and TDI S' <9.5 mm RESULTS: Among the entire cohort, 624 (70%) showed normal RV, 92 (10%) isolated RV dilatation, 154 (17%) isolated RV dysfunction, and 25 (3%) both RV dilatation and dysfunction. Non-surviving patients showed a significantly higher rate of RV alteration at multivariable analysis, RV status was found to be an independent predictor for higher in-hospital mortality beside Euroscore II. CONCLUSIONS: This prospective multicenter observation study shows the importance to assess RV preoperatively and to include both RV function and dimension in a risk score model such as Euroscore II to implement its predictivity, since PH cannot always mirror the status of the right ventricle.

[Surgical treatment of aortic valve disease: early results of a 360° minimally invasive approach]. / Trattamento chirurgico della valvulopatia aortica: esperienza iniziale di un approccio mini-invasivo a 360°.

BACKGROUND: Over the years, with the introduction of minimally invasive techniques and technologies aimed at reducing surgical trauma, aortic valve surgery has considerably developed and improved. Our approach includes: reduced incisions (upper "J" ministernomy or anterior right minithoracotomy), "ultra fast-track" anesthesia protocols, sutureless and rapid deployment valve prostheses and miniaturized circuits of extracorporeal circulation. The aim of this study was to evaluate the clinical outcomes associated with this multidisciplinary approach. METHODS: Between October 2016 and November 2018, 429 patients underwent isolated aortic valve replacement at the Cardiac Surgery Unit of the "Ospedali Riuniti" of Ancona, Italy. Overall, 91 patients (21.2%) were operated according to our minimally invasive approach. A severe aortic valve stenosis was the indication for surgery in 90.1% of patients, aortic valve insufficiency in the remaining 18.7%. RESULTS: There were neither in-hospital deaths nor major or minor neurological events. Atrial fibrillation was the main postoperative complications (n=26, 28.6%). Four patients (4.4%) underwent permanent pacemaker implantation due to third-degree atrioventricular block, and a surgical bleeding revision was performed in 3.3%. No episodes of respiratory failure were reported. The median length of hospital stay was 6 days (5-8 days). CONCLUSIONS: Our initial experience with a 360° minimally invasive approach for the treatment of patients undergoing aortic valve replacement shows encouraging clinical outcomes; this approach may lead to an improved perception of surgery both by patients and their families. However, further clinical studies are needed to evaluate the long-term results.

Mini Bentall operation: technical considerations.

Bentall operation via median sternotomy has been largely shown to be safe and long-term efficacious and currently represents the "gold standard" intervention in patients presenting with aortic valve and root disease. However, over the last years, minimally invasive techniques have gained wider clinical application in cardiac surgery. In particular, minimally invasive aortic valve replacement through ministernotomy has shown excellent outcomes and becomes the first choice approach in numerous experienced centers. Based on these favorable results, ministernotomy approach has also been proposed for complex cardiac procedures such as aortic root replacement and arch surgery. Herein, we present our technique for minimally invasive Bentall operation using a ministernotomy approach.

Ultra fast-track minimally invasive aortic valve replacement: going beyond reduced incisions.

Aortic valve replacement (AVR) via a median sternotomy approach has been largely reported to be safe and long-term efficacious, and currently represents the 'gold standard' approach for aortic stenosis treatment. However, aortic valve surgery has undergone continuous development over the last years, involving less invasive techniques and new technologies to reduce the traumatic impact of the intervention and extend the operability toward increasingly high-risk patients. Indeed, minimally invasive AVR and transcatheter aortic valve replacement caseload have steadily increased leading to a paradigm shift in the treatment of aortic valve disease. In this setting, we have established a multidisciplinary minimally invasive programme to treat patients who require AVR. Herein, we present our approach including (i) reduced chest incision (through a J ministernotomy), aiming to reduce the traumatic impact of the surgical procedure, to decrease blood loss, postoperative pain and wound complications and to increase patient's satisfaction; (ii) rapid-deployment AVR, to reduce operative times, to facilitate minimally invasive approach and to improve haemodynamic outcomes; (iii) minimal invasive extracorporeal circulation system, to improve end-organ protection, to decrease systemic inflammatory response and to promote fast-track anaesthesia and (iv) ultra fast-track anaesthesia, to decrease the rate of postoperative complications and assure better and earlier recovery.

Prevention of atrial fibrillation and inflammatory response after on-pump coronary artery bypass using different statin dosages: a randomized, controlled trial.

BACKGROUND: This randomized controlled trial aimed to evaluate the effects of seven-day preoperative treatment with two different dosages of atorvastatin on the incidence of postoperative atrial fibrillation (POAF) and release of inflammatory markers such as high-sensitive C-reactive protein (hsCRP) and interleukin-6 in patients undergoing elective first-time on-pump coronary artery bypass grafting (CABG). METHODS: The cohort study comprised 212 consecutive patients, already taking statins, who underwent elective first-time CABG with cardiopulmonary bypass without history of atrial fibrillation (AF). Patients were randomly divided into two groups: those who received atorvastatin 40 mg (TOR40 group, 111 patients) and those who received 80 mg (TOR80 group, 101 patients) once a day for 7 days before the planned operation. The primary endpoint was the incidence of AF. The secondary endpoints were the postoperative variations of inflammatory markers, hospital length of stay, and the incidence of major adverse cardiac and clinical events. RESULTS: A total of 26 patients (23.6 %) pretreated with atorvastatin 40 mg and 16 (15.8 %) patients pretreated with atorvastatin 80 mg had postoperative AF but the difference did not reach the statistical significance (p = 0.157). Median values of interleukin-6 and hsCRP at 12 and 24 h did not have differences between the two groups. No statistically significant differences in the other secondary endpoints were detected. CONCLUSIONS: According to our result, 7-day preoperative treatment with a high dose of atorvastatin is associated with a trend to a decrease in the incidence of POAF compared with treatment at a lower dose, although it does not impact on the level of inflammatory markers.

Saphenous Vein Graft Wrapping by Nitinol Mesh: A Word of Caution.

BACKGROUND: Saphenous vein conduits are still used in a large proportion of coronary artery bypass graft (CABG) operations. A recently commercialized nitinol mesh seems to improve venous graft patency. The aim of this study was to control nitinol mesh vein graft patency in a series of isolated CABG patients by computed tomographic (CT) scan. METHODS: In 25 patients (mean age: 61.0 ± 9.65 years), operated for isolated CABG, the eSVS nitinol mesh (Kips Bay Medical Inc., Minneapolis, Minnesota, United States) was used to wrap one vein graft in each patient. Nitinol mesh vein graft was used to revascularize the right coronary (4 patients; 16%), the posterior descending (18 patients; 72%), and the obtuse marginal (3 patients; 12%) arteries. CT scans were performed at 1, 6, and 12 months postoperatively. RESULTS: The procedure was uneventful in all patients. CT controls showed an overall patency rate of 86.9, 42.7, and 34.1% at 1, 6, and 12 months, respectively. The 4 mm mesh had a significantly higher patency rate at 12 months (83.33%) than the 3.5 mm one which showed quite unsatisfactory results (20%) (p = 0.02). Patients with graft occlusion underwent stress testing which was mildly positive in two cases. One of them underwent a percutaneous revascularization. CONCLUSION: Despite promising early results, use of nitinol mesh for saphenous veins was disappointing in our experience. Further refinements are probably needed.

Conventional surgery results in patients originally referred for transcatheter aortic valve implantation.

AIMS: Transcatheter aortic valve implantation (TAVI) is increasingly considered as a viable alternative to conventional aortic valve replacement (AVR) in high-risk patients. Long-term results, however, are still scarce and medical community hesitates in enlarging indications to lower-risk patients. Moreover, available devices are expensive and a strict potential candidate selection is necessary. METHODS: From April 2008 to August 2012, a total of 212 patients, originally referred for percutaneous treatment, were thoroughly evaluated by the aortic team of our department in order to choose the optimal procedure. Of them, 55 patients (35 women; 20 men) were considered as still acceptable candidates for conventional AVR. RESULTS: Mean age was 80.7 ±â€Š4.7 years; mean additive and logistic Euroscore I were 9.7 ±â€Š1.8 and 17.8 ±â€Š9.5%, respectively. Mean Euroscore II was 7.9 ±â€Š5.5%. Mean New York Heart Association class was 2.9 ±â€Š0.5. The majority of patients (87.2%) presented a geriatric frailty score of 0-1. Four patients showed a heavily calcified ascending aorta, and five patients (9%) underwent reoperations. Hospital mortality was 10.9% (six patients). Mean follow-up was 535.9 ±â€Š407.4 days (range: 6-1365 days). Six other patients died during this period for a mean survival of 74.4 ±â€Š6.9% at 2 years. Mean New York Heart Association class at 1 year was 1.25 ±â€Š0.5 (P < 0.01 vs. preoperative value). CONCLUSION: AVR should be indicated with caution in high-risk patients originally referred for TAVI. Despite medium-term results being good, with excellent functional status, hospital mortality is not negligible.

Ten years' follow-up of single-surgeon minimally invasive reparative surgery for degenerative mitral valve disease.

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.

Absorption of carbon dioxide during endoscopic vein harvest.

OBJECTIVES: Carbon dioxide (CO(2)) insufflation was used by some devices for endoscopic vein harvest to create a subcutaneous tunnel and facilitate the vein harvest. In the literature, some cases of CO(2) micro- and macro-embolisms or hypercarbia during this procedure are described. The purpose of this study was to evaluate if the use of an open CO(2) system rather than a sealed system might be associated with different CO(2) absorption during the procedure. METHODS: Patients were randomized into two groups: those patients in the first group were submitted to endoscopic vein harvest using a sealed CO(2) insufflation; in the second group, the harvest was undertaken with an open CO(2) insufflation. Partial pressure of CO(2) in the arterial blood (PaCO(2)) and end-tidal CO(2) (ETCO(2)) was recorded following anaesthesia induction and before the endoscopic procedure (T0), every 10 min during the endoscopic step (T1) and end after 10 min from the CO(2) insufflation termination (T2). RESULTS: A total of 60 patients were enrolled. PaCO(2) increased significantly between T0, T1 and T2 in both groups (P = 0.0001) during the endoscopic harvest, but the PaCO(2) level was significantly higher in the group that used the sealed system (44.5 ± 7.9 vs 39.7 ± 7.9 mmHg) at the end of the procedure (P = 0.01). No significant differences between end-tidal CO(2) measured at the same intervals between groups were detected. CONCLUSIONS: There was a constant increase in the blood gas concentration compared with the basal pre-procedure values. Sealed systems were associated with a significantly higher CO(2) concentration at the end of the procedure compared with the open ones.

Coronary graft use of a new external mesh support.

Poor quality veins may result in early graft failure after coronary artery bypass grafting. Vein remodelling by means of external scaffolds has been attempted by various products. Here, we describe our use of a new external mesh support that is generally used in peripheral vascular bypasses in order to remodel a poor quality vein used in coronary revascularization. Early CT control demonstrated a good result.

Pulmonary artery banding: when is the use of a telemetrically adjustable device indicated?

Proponents of a telemetrically adjustable pulmonary artery band (PAB) device have cited simplified postoperative management and shortened length of stay as advantages associated with that technology. This report concerns a recent experience with both conventional pulmonary artery banding (conv-PAB) and the telemetrically adjustable PAB FloWatch (FW-PAB). From January 2005 through December 2008, 19 consecutive infants underwent either conv-PAB (8 patients, mean age 3.5 months, mean weight 4.1 kg) or FW-PAB (11 patients, mean age 2.6 months, mean weight 3.1 kg). Indications for PAB were left ventricular retraining (1 patient in FW-PAB), palliation prior to biventricular repair (7 patients in conv-PAB and 10 in FW-PAB group), and staged univentricular repair (1 patient in conv-PAB). In-hospital mortality was 0%. In the FW-PAB group, 1 FloWatch device was removed because of hemodynamic compromise related to the bulk of the device. There were no major complications in the conv-PAB group and no differences between groups with respect to postoperative ventilation time or length of stay in the intensive care unit or in hospital. In the FW-PAB group, a mean of 3.1 ± 1.7 regulations per patient were undertaken. Of the regulations, 85% (29/34) were adjustments to tighten the device, and 15% (5/34) were to loosen it. During follow-up, 8 patients underwent intracardiac repair and pulmonary artery debanding: 4 in the conv-PAB group and 4 in the FW-PAB group. The course of patients in both groups after PAB were similar. Major differences in length of stay and resource utilization were not apparent.

Synthesis and assignment of absolute configuration of the iridoid 9-deoxygelsemide.

The first enantioselective synthesis of 9-deoxygelsemide, belonging to a rare group of iridoids isolated from Gelsemium plants, is described. The key synthetic steps are a variant of the Woodward-Prevost reaction to install the characteristic cis-alpha-1,2-dioxygenated system at C-6 and C-7 with complete diastereoselectivity. Construction of the dihydropyran ring was achieved via formylation of lactone I, followed by dehydration of the corresponding lactol. The synthesis allowed assignment of absolute configuration to 9-deoxygelsemide and related iridoids.

Reimplantation of an anomalous coronary artery arising from the pulmonary artery.

A case of anomalous origin of the left coronary artery from the pulmonary artery in a patient with the origin of the coronary opposite to the aorta is reported. Between many surgical options we conclude to reestablish a double coronary system reconnecting the coronary through a conduit created with a pulmonary wall baffle and an autologous pericardial patch.

Edge-to-edge technique: is it also useful in children?

OBJECTIVE: Mitral valve prolapse is a rare condition and represents a challenge for cardiac surgeons. Many techniques have been described to treat the wide spectrum of abnormalities causing mitral valve regurgitation but the low incidence of these abnormalities is the cause of the relatively poor experience of many institutions. METHODS: From April 2005 to September 2006, five patients underwent isolated mitral valve repair with the edge-to-edge technique for anterior or bileaflet prolapse. Three patients also had a Gore-Tex strip to reinforce the posterior annulus, whereas two had a 26-size soft incomplete ring annuloplasty. RESULTS: There was no death and none of the patients required reoperation. None of the patients had mitral regurgitation more than 1+ at a mean follow-up of 30 months. None of the patients had mitral stenosis or any valve-related event. CONCLUSION: The edge-to-edge technique is a well tolerated and useful technique for the anterior or bileaflet prolapse of the mitral valve. Although many techniques have been described with good results, in many anatomical settings and in small patients, edge-to-edge is a good option and might not interfere with the growth of the valve. Early results are encouraging but a longer follow-up is needed to evaluate the long-term prognosis.
