Int J Cardiol 2023; 391:131277. [PMID: 37598910 DOI: 10.1016/j.ijcard.2023.131277] [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: 04/20/2023] [Revised: 08/04/2023] [Accepted: 08/17/2023] [Indexed: 08/22/2023]
Abstract
OBJECTIVE Post-infarction myocardial scar as detected by cardiac magnetic resonance (CMR) is associated with adverse left ventricular (LV) remodeling and negatively affects the prognosis. We sought to analyze the impact of left ventricular restoration (LVR) with asynergic scar exclusion on long-term outcomes for patients with ischemic heart failure (IHF). METHODS From January 2005, 134 consecutive patients with IHF underwent scar-exclusive LVR. Among the 131 survivors, 108 patients had paired late gadolinium enhancement (LGE)-CMR preoperatively and one year after, and represent the study population. Patients were divided into two groups according to whether their post-LVR residual percentage of scarred LV perimeter was <35% (%Scar <35; n = 55) or more (%Scar ≥35; n = 53). We compared the two groups, by looking at LGE-CMR outcomes, and at long-term survival and cardiac event (hospitalization for cardiac causes)-free survival. RESULTS Postoperative LV end-systolic volume index decreased significantly and ejection fraction increased with significant increase in stroke volume index (P < 0.05 for both). LV diastolic function of the left atrial volume index was significantly improved in patients with residual %Scar <35 than in those with %Scar ≥35 (P interaction = 0.005). Median survival in patients with residual %Scar <35 and ≥ 35 were 8.3 (4.5-12.2) years and 6.8 (1.8-11.8) years respectively (P = 0.106). Median cardiac event-free survival in patients with %Scar <35 and ≥ 35 were 8.0 (3.9-12.1) years and 4.8 (0.8-8.8) years respectively (P < 0.001). CONCLUSIONS Scar-exclusive LVR yielded sustainable improvement in LV function and favorable long-term survival regardless of the extent of residual scar. The LVR should be performed to attain scar exclusion in the surgical treatment for IHF, which in turn might protectively affect LV diastolic function and cardiac event-free survival.

Transapical ventricular reshaping reduces functional mitral regurgitation and improves ventricular function in a preclinical model of ischemic cardiomyopathy. J Thorac Cardiovasc Surg 2023:S0022-5223(23)00724-9. [PMID: 37597738 PMCID: PMC10874464 DOI: 10.1016/j.jtcvs.2023.08.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 07/27/2023] [Accepted: 08/01/2023] [Indexed: 08/21/2023]
Abstract
OBJECTIVE A significant proportion of patients with advanced heart failure present with dilated left ventricles and functional mitral regurgitation. These patients currently have limited treatment options. The MitraClip device (Abbott) has benefited only patients with smaller left ventricles (end-diastolic dimension <70 mm), whereas those with larger left ventricles did not benefit. A possible explanation is correcting functional mitral regurgitation alone may not adequately reduce the wall stresses of a dilated left ventricle. We have developed a beating-heart device that not only approximates the papillary muscles to reduce functional mitral regurgitation but also modifies the left ventricle size and shape to reduce wall stress. METHODS Yorkshire swine (n = 16) had a myocardial infarction induced by permanent occlusion of the left circumflex with intracoronary ethanol. Three months later, the animals developed heart failure and moderate or greater functional mitral regurgitation. Through a transapical approach, the new device was implanted under echocardiography guidance to reshape the left ventricle and correct functional mitral regurgitation. The acute impact of this approach on the mitral valve and left ventricle was assessed with echocardiography and invasive hemodynamics. RESULTS After reshaping, echocardiography showed a decrease in end-diastolic volume by 36.3 ± 30.5 mL (P < .001), a decrease in sphericity index by 0.143 ± 0.087 (P < .001), and an increase in ejection fraction of 5.90% ± 6.38% (P < .01). Mitral valve tenting area was reduced by 39.29 ± 33.66 mm2 (P < .001), coaptation length was increased by 2.12 ± 1.02 mm (P < .001), and posterior excursion angle was improved by 9.07° ± 9.14° (P < .01), resulting in functional mitral regurgitation reduction. CONCLUSIONS Correction of functional mitral regurgitation with favorable changes in mitral valve geometry and reduction in left ventricle geometry is possible with the proposed device.

Abstract
Abstract
The management of patients with coronary artery disease and heart failure has been debated for years. In the 1980’s Braunwald coined the words “viability” and “stunning”. Multiple trials have been done since then. Since the early eighties coronary bypass grafting was considered as gold standard for patients with impaired left ventricular fraction and coronary artery disease. Since then, nuclear imaging studies have been used to evaluate the “viability” of the impaired areas and to decide if revascularisation would be reasonable. Beginning with the CASS study and ending with the more recent STICH study we aim to provide a “bird’s eye view” of the pros and cons for revascularisation. In addition, we aim to shed some light on the daily advancements in medical management, including devices and not just medication. We therefore chose the title “Back to the future” or maybe not.

Abstract
Objectives This pilot study evaluates the association of relative wall thickness (RWT) on survival in patients with ischemic cardiomyopathy (ICM). We hypothesized that patients with preserved RWT may be better candidates for surgical ventricular restoration than those with thinner RWT. Methods Echocardiography was performed in 165 consecutive patients (aged 58.2 ± 14.7 years) divided into 2 groups based on RWT values. Group 1 had patients with preserved RWT and group 2 had patients with reduced RWT. Results There were 120 (72.7%) patients with hypertension and 112 (67.8%) patients had diabetes mellitus. The patients with preserved RWT (group 1) had significantly more hypertension and diabetes. The patients with decreased RWT (group 2) were in a higher New York Heart Association functional class and had significantly greater incidence of anterior wall myocardial infarction. The entire cohort was followed over 24 months (group 1: n = 117 and group 2: n = 48). The overall all-cause mortality in group 1 (preserved RWT) was 7 (5.9%) and in group 2 (reduced RWT) was 35 (72.9%) (P < .0001). When readmission for congestive heart failure was analyzed, group 2 patients with lower RWT (P < .0001) had an increased rate of readmissions for heart failure. Conclusions In patients with ischemic cardiomyopathy, a lower RWT indicative of dilated LV remodeling was associated with increased mortality and readmission for heart failure. The RWT may be a simple benchmark of viable or contractile myocardium in ICM. It can be hypothesized that patients with preserved RWT may benefit from surgical ventricular restoration.

Abstract
Patients with symptomatic post-ischemic dilative myocardiopathy of the left ventricle require, in selected cases, an operation to reshape and reduce the volume of the left ventricular chamber, in addition to surgical myocardial revascularization and mitral valve repair, with the aim of prolonging survival, improving the quality of life and minimizing the need for re-hospitalizations related to recurrent heart failure. This procedure is called surgical ventricular restoration (SVR), and is a useful tool for the treatment of heart failure patients as an alternative to heart transplant. This article provides an overview of surgical ventricular restoration for the treatment of dilative ischemic myocardiopathy. It illustrates several surgical options, describes the operative details, and discusses the correct indications for the procedure. Finally, an interesting protocol for one-step cell therapy during SVR is proposed, as an innovative treatment for heart failure patients.

Abstract
Coronary angiography has been recommended in all patients with suspected chronic coronary syndrome and left ventricular ejection fraction (LVEF) ≤35%. The role of ischemia testing, for example, through stress-rest myocardial perfusion scintigraphy (MPS), for risk prediction is not well established. METHODS We evaluated 1576 consecutive patients referred to MPS and stratified into 3 LV ejection fraction (LVEF) categories: ≤35%, 36-49%, and ≥ 50%. RESULTS Patients with LVEF ≤35% were oldest, most often men, and with the highest likelihood of prior early (elective or urgent) coronary revascularization. They had also the highest values or summed stress score (SSS), summed rest score (SRS), and summed difference score (SDS), as well as the highest frequency of significant coronary artery disease, and a greater number of diseased vessels. FOLLOW-UP In this subgroup, 32 cardiovascular death or non-fatal myocardial infarction (MI) (21%), 35 all-cause deaths (22%), and 37 cardiovascular deaths, non-fatal MI, or late revascularizations (27%) were recorded with the shortest survival among all LVEF classes. SRS, SSS, and SDS had very low area under the curve values for the prediction of the 3 endpoints, with very high cut-offs, respectively. SRS and SSS cut-offs predicted a worse outcome in Cox regression models including the number of diseased vessels and early revascularization. CONCLUSIONS In patients with LVEF ≤35%, SRS and SSS are less predictive of outcome than in patients with better preserved systolic dysfunction, but their cut-offs retain independent prognostic significance from the number of vessels with significant stenoses and from early revascularization.

Abstract
Background Technique of surgical ventricular restoration (SVR) may impact its outcomes. Therefore, we conducted a meta-analysis of studies on SVR performed by using different techniques and studied outcomes. Methods Scientific databases were searched for studies on SVR. End points assessed were NYHA class, left ventricular ejection fraction (LVEF), end-systolic volume index (ESVI), sphericity index, apical rotations, mortality, and re-admissions for heart failure. Results Circular patch use showed significant increases in LVEF by 9.53% (7.62, 11.45), decreases in ESVI by - 35.16 ml (- 44.97, - 25.34), improvements in NYHA class by - 1.29 (- 1.45, - 1.13), and decreases in sphericity index by - 0.04 (- 0.08, 0.00) . In studies using rectangular patch, the LVEF showed an increase by 5.75% (3.52, 7.98,), the NYHA class improved by - 2.45 (- 2.59, - 2.32). The decrease in ESVI was - 40.36 ml (- 62.2, - 18.52). The apical rotation increased by 3.45 0 (0.62, 6.29,). Re-admission for heart failure and mortality was less.When the magnitude of ESVI decrease were compared within studies using rectangular patch, the greatest decrease in ESVI was notedwith use of a rectangular patch. (- 59 ml versus - 40 ml a very narrow patch and - 22 ml use of oval patch) The improvements in sphericity index at 2 years in use of rectangular patch study was - 0.78 ± 0.11 versus 0.00 ± 0.03 in use of oval patch study. Conclusions Rectangular patch use resulted in maximal decreases in ESVI and sphericity index. Mortality and re-admissions for heart failure were also significantly less at mid-term after SVR.

Abstract
Optimal treatment for patients with ischemic heart disease and severe left ventricular dysfunction is a debatable subject in the literature. The largest and only trial on the subject so far is the Surgical Treatment for Ischemic Heart Failure trial. This trial compared coronary artery bypass grafting with optimal medical treatment in one arm versus coronary artery bypass grafting with surgical ventricular restoration in the second arm. Recently, the 10-year follow-up data of various subsets of the trial have been published. This study reviews various pertinent clinical issues related to the trial and its sub-studies and their relevance in routine modern-day clinical practice.

Abstract
Objective To compare the outcomes of isolated coronary artery bypass grafting (CABG) versus surgical ventricular restoration (SVR) with or without CABG for patients with ischemic cardiomyopathy (ICM). Methods Retrospectively, 49 patients with ICM and severe LV dysfunction (LVEF < 35%) who underwent SVR with or without CABG from January 2009 to December 2016 at a single institution was compared with 49 patients who underwent isolated CABG. The two groups were matched for preoperative clinical and echocardiographic parameters including left ventricular end-diastolic diameter (LVIDd), left ventricular end-systolic diameter (LVIDs), left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), and left ventricular end-systolic volume (LVESV). Primary outcomes analyzed included early mortality, late mortality, and major adverse cardiac or cerebrovascular events (MACCE). Secondary outcomes analyzed included echocardiographic parameters of left ventricular volume and function-indexed left ventricular end-diastolic volume (LVEDVi), indexed left ventricular end-systolic volume (LVESVi), and LVEF. Cox and survival analysis was performed. Results Early and late mortality in SVR vs. CABG groups were 4 (8.1%) and 6 (12.2%) vs. 1 (2%) and 5 (10.2%) respectively. Mean improvement in LVEF was 3.39 ± 7.51 compared to 4.97 ± 5.45 between the two groups at 3-month follow-up. Mean improvement in LVEF was 5.1 ± 8.3 in the SVR group vs 5.9 ± 7.1 in the CABG group at the last follow-up. There was no statistically significant improvement between the two groups in terms of LVEF at 3 months or the last follow-up. There were statistically significant differences between LVEDVi and LVESVi between the two groups at 3 months and the last follow-up. The 5-year rates of survival were 85 ± 6 and 82 ± 9% for SVR and CABG groups respectively. The 5-year rates of freedom from MACCE were 75 ± 7 and 60 ± 11% for SVR and CABG groups respectively. Conclusion Compared with isolated CABG, SVR plus CABG results in equivalent late mortality and better left ventricular reverse remodeling (as evidenced by LV volume reduction) and better freedom from MACCE at 5-year follow-up.

Abstract
Mitral regurgitation (MR) occurs when any of the valve and ventricular mitral apparatus components are disturbed. As MR progresses, left ventricular remodelling occurs, ultimately causing heart failure when the enlarging left ventricle (LV) loses its conical shape and becomes globular. Heart failure and lethal ventricular arrhythmias may develop if the left ventricular end-systolic volume index exceeds 55 ml/m2. These adverse changes persist despite satisfactory correction of the annular component of MR. Our goal was to describe this process and summarize evolving interventions that reduce the volume of the left ventricle and rebuild its elliptical shape. This 'valve/ventricle' approach addresses the spherical ventricular culprit and offsets the limits of treating MR by correcting only its annular component.

Abstract
OBJECTIVES To report the mid-term results of our surgical ventricular restoration procedure, called the endocardial linear infarct exclusion technique (ELIET), for ischaemic cardiomyopathy. METHODS From 2006 to 2015, 43 consecutive patients who underwent surgical ventricular restoration with ELIET for ischaemic cardiomyopathy were retrospectively analysed. RESULTS The mean age of patients at surgery was 65.3 ± 9.2 years and EuroSCORE II was 13.7 ± 12.0% (median 9.3%). The mean number of distal anastomoses of coronary artery bypass was 2.8 ± 1.5. A concomitant mitral procedure was performed in 58.1% of patients. The hospital mortality rate was 11.6% (5 patients). The ejection fraction was improved from 24.1 ± 9.2% to 31.7 ± 8.2% in 2 weeks after surgery. The end-systolic left ventricular volume index was effectively reduced, irrespective of performing a concomitant mitral procedure (reduction rate, ELIET: 35.6% vs ELIET + mitral: 39.2%). After ELIET, the sphericity index of the left ventricle did not worsen, and the conicity index was significantly improved. The 5-year estimated rates of survival and freedom from cardiac events were 71.3 ± 7.9 and 61.1 ± 8.3%, respectively. A concomitant mitral procedure was significantly associated with cardiac events based on univariate Cox hazard analysis. CONCLUSIONS This study showed that ELIET can effectively reduce the ventricular volume and create an ellipsoidal left ventricle.

Abstract
Heart failure (HF) remains the leading cause of hospitalization in older adults and is associated with increased morbidity and mortality despite the use of guideline-directed medical therapy. There has been tremendous progress in the development of novel transcatheter and interventional therapies for HF over the past decade. The evolution of structural heart disease interventions and interventional HF has led to a multidisciplinary heart team approach in the management of HF patients. Careful selection of the appropriate patient population and end points in future randomized controlled trials will be crucial to demonstrate the potential efficacy of the novel interventional HF therapies.

Abstract
The burden of heart failure has long plagued the productive years of the population, with therapeutic advances in the timely treatment of ischemic heart disease decreasing its associated mortality. Angiotensin-converting enzyme inhibitors and β-blockers have impacted heart failure therapeutics in a revolutionary way. The importance of blockade of the renin-angiotensin system and adrenergic stimulation are fully accepted concepts that apply in young and old, symptomatic and asymptomatic, borderline low and very low Ejection Fraction (EF), left ventricular failure and biventricular failure. Despite several interventions, both pharmaceutical and device based for the treatment of ensuing heart failure, the incidence is increasing in large proportions. Newer molecules like sacubitril show more promise. Despite these novel therapies, several patients relentlessly progress to a stage of advanced heart failure. The use of left-ventricular-assist devices has variable clinical benefit, with some patients progressing to heart transplantation.

Abstract
OBJECTIVES We aimed to investigate the outcomes of surgical ventricular reconstruction (SVR) for ischaemic cardiomyopathy and to identify ideal candidates for this procedure using cardiac magnetic resonance imaging (MRI) studies. METHODS We retrospectively examined 50 patients who underwent SVR and were preoperatively evaluated using cardiac MRI from 2004 to 2014. Cine MRI and gadolinium-enhanced MRI were performed to evaluate left ventricular (LV) volume and scarring. The midterm (median, 2.5 years) risk factors of cardiac death or major adverse cardiac events (MACEs) were analysed. Patients were divided into three groups-those with preoperative indexed LV end-systolic volume (LVESVI) of ≤100 ml/m2 (Group 1), those with LVESVI of >100 and ≤130 ml/m2 (Group 2) and those with LVESVI of >130 ml/m2 (Group 3)-and examined. RESULTS In total, 17 patients exhibited MACEs at follow-up. Kaplan-Meier analysis showed that the 5-year rate of freedom from MACEs was 66%. The Cox hazard model indicated that preoperative LVESVI was the only significant predictor for MACEs (P = 0.006; hazard ratio, 1.02; 95% confidence interval, 1.01-1.04). Moreover, a significant reduction in LVESVI and an increase in LV ejection fraction (LVEF) were observed early after SVR (preoperative versus postoperative: LVESVI, 110 ± 44 vs 68 ± 28 ml/m2, P < 0.001; LVEF, 24.3 ± 10.3 vs 32.0 ± 10.4%, P < 0.001) and at follow-up (LVESVI, 61 ± 28 ml/m2, P < 0.001; LVEF, 36.5 ± 11.5%, P < 0.001). Although no difference was observed between the groups at follow-up, LVEF and LVESVI primarily improved in Group 2. LVEF improvement was significantly greater in Group 2 than in Group 1 (%increase in LVEF: Group 1, 6%; Group 2, 18%; P = 0.008). In patients with a preoperative LVESVI of >130 ml/m2, the number of non-viable segments was a significant risk factor for MACEs. CONCLUSIONS Patients with preoperative LVESVI ranging from 100 to 130 ml/m2 had fairly better outcomes, and the percentage improvement in LVEF and the percentage reduction in LVESVI were more pronounced in these patients. Hence, accurate preoperative assessments of LV volume and viability testing using cardiac MRI studies are essential for better stratification of the SVR procedure.

Abstract
OBJECTIVE The history of left ventricular reconstruction has demonstrated that the full spectrum of recoverable physiologic parameters is essential for a good functional result. We report the long-term outcome of a new surgical technique that arranges myocardial fibers in a near-normal disposition, also recovering left ventricular twisting. METHODS Between May 2006 and October 2013, 29 consecutive patients with previous anterior myocardial infarction and heart failure symptoms underwent physiologic left ventricular reconstruction surgery and coronary revascularization. Patients were examined by means of standard echocardiography and 2-dimensional speckle tracking at 8 time steps until 7 years after surgery. Ten geometric and functional parameters were evaluated at each step and analyzed by the linear mixed model test. RESULTS Hospital mortality was 0%. The mean percentage of indexed end-diastolic and end-systolic volume reduction was 45.7% and 50.9%, respectively. Ejection fraction and all of the volumes were significantly different in the postoperative period with a steady correction during time. Diastolic parameters were not worsened by surgical reconstruction. Ejection fraction and deceleration time showed a significant improvement during time. Left ventricular torsion increased immediately after the surgical correction from 2.8 ± 4.4 degrees to 8.7 ± 3.9 degrees (P = .02) and was still present 4 years after surgery. CONCLUSIONS Surgical conduction of ventricular reconstruction should be standardized to achieve the full spectrum of recoverable physiologic parameters. The renewal of ventricular torsion should be pursued as an adjunctive element of ventricular efficiency, mainly in ventricles that work at a critical level in the Frank-Starling relationship and pressure-volume loop.

Abstract
Heart failure is a growing epidemic, with more patients living longer and suffering from this disease. There is a growing segment of patients who have persistent symptoms despite pharmacologic therapy. In an era when transplants are rare, the need for devices and interventions that can assist ventricular function is paramount. This review goes through the devices used in heart failure, including left ventricular reconstruction, aortic counterpulsation, short-term mechanical circulatory support, long-term mechanical circulatory support, and right heart interventions.

Abstract
OBJECTIVES Non-transplant surgery for dilated cardiomyopathy (DCM) has been in the process of development. We performed posterior restoration for dilated akinetic or dyskinetic lesions in patients with DCM and obtained favourable outcomes. The early and long-term results of the procedures are discussed. METHODS Between 2005 and 2013, posterior restoration procedures (PRPs) for DCM were electively performed in 58 patients (17 with ischaemic and 41 with non-ischaemic DCM). There were 45 men and 13 women with a mean age of 56 ± 12 years old. The mean preoperative ejection fraction was 24% and the preoperative New York Heart Association functional class was Class III in 24 and Class IV in 34 patients with intravenous inotrope support. Indications for PRPs were determined by using speckle-tracking echocardiography of the posterior region of the left ventricle before surgery (GE ultrasound machine, Vivid 7 or Vivid E9). After cardioplegic arrest, mitral surgery or coronary artery bypass grafting (CABG) was performed and the posterior left ventricular (LV) muscle between bilateral papillary muscles was incised or resected. The LV apex was preserved and cryoablation was applied between the cut edge and the posterior mitral annulus. All patients were followed up by transthoracic echocardiography. RESULTS In addition to PRP, mitral surgery was performed in 56 (plasty 51, replacement 5), tricuspid annuloplasty in 21, CABG in 17, cardiac resynchronization therapy in 6 and LV lead implantation in 27 patients. Perioperative intra-aortic balloon pumping was used in 9 patients and there was no hospital mortality. After the operation, 35 patients (60%) improved their functional class to Class I or II. In the late follow-up, there were 14 cardiac deaths (congestive heart failure 10, ventricular arrhythmia 4). The 3- and 8-year survival rates were 77 or 66%, respectively. CONCLUSIONS DCM with posterior akinesis or dyskinesis indicated by speckle-tracking echocardiography can be surgically treated with PRP. Our results demonstrated that 60% of the selected patients could avoid heart transplantation with relief of their symptoms.

Abstract
OBJECTIVES Although circular ventricular resection techniques are the gold standard of left ventricular (LV) restoration, these techniques can lead to suboptimal results. Postoperative systolic resection can be inadequate, because it must be planned on a heart stopped in diastole. Low cardiac output due to insufficient LV volume results in a potentially unstable condition, and cannot be corrected. Our aim was to find a preoperative method to minimize risk and maximize outcome with ventricular restoration. METHODS We created a novel method combining surgery with gadolinium-enhanced magnetic resonance to construct a preoperative 3D systolic heart model. The model was utilized to determine resection points that could be intraoperatively used. According to our calculations with the predetermined resection line, the calculated percentage reduction in LV volume was above 30%, and LV volumes were predicted above normal values; thus, performing the operation using these resection points is likely to be safe and effective. We had a mixed, real-life patient group: mitral insufficiency or pulmonary hypertension were not exclusion criteria. RESULTS Forty-one procedures (12 concomitant mitral valve plasty) were done on consecutive patients in a single-centre experience. The incidence rate of major adverse clinical events was 32% postoperatively (n = 13). Control MRI showed a significant improvement in ejection fraction (18.3 ± 4.3 vs 31.3 ± 3.3; P = 0.04). All patients improved their New York Heart Association (NYHA) class postoperatively (40 patients NYHA III/IV versus 40 NYHA I/II). During long-term follow-up, 1 patient died due to end-stage heart failure. CONCLUSIONS Using this model, we were able to find the optimal resection line providing an excellent postoperative result, thus minimizing the risk of low cardiac output syndrome.

Abstract
OBJECTIVES In the Surgical Treatment for Ischemic Heart Failure trial, surgical ventricular reconstruction plus coronary artery bypass surgery was not associated with a reduction in the rate of death or cardiac hospitalization compared with bypass alone. We hypothesized that the absence of viable myocardium identifies patients with coronary artery disease and left ventricular dysfunction who have a greater benefit with coronary artery bypass graft surgery and surgical ventricular reconstruction compared with bypass alone. METHODS Myocardial viability was assessed by single photon computed tomography in 267 of the 1000 patients randomized to bypass or bypass plus surgical ventricular reconstruction in the Surgical Treatment for Ischemic Heart Failure. Myocardial viability was assessed on a per patient basis and regionally according to prespecified criteria. RESULTS At 3 years, there was no difference in mortality or the combined outcome of death or cardiac hospitalization between those with and without viability, and there was no significant interaction between the type of surgery and the global viability status with respect to mortality or death plus cardiac hospitalization. Furthermore, there was no difference in mortality or death plus cardiac hospitalization between those with and without anterior wall or apical scar, and no significant interaction between the presence of scar in these regions and the type of surgery with respect to mortality. CONCLUSIONS In patients with coronary artery disease and severe regional left ventricular dysfunction, assessment of myocardial viability does not identify patients who will derive a mortality benefit from adding surgical ventricular reconstruction to coronary artery bypass graft surgery.

Abstract
The surgical strategy for ischemic mitral regurgitation (MR) remains controversial. Ischemic MR is a secondary valve disease caused by left ventricular (LV) remodeling and subsequent papillary muscle displacement, usually without structural valve lesions. Reduction annuloplasty is the standard surgical procedure for this condition, though it cannot clearly provide a survival benefit for those with LV dysfunction and is associated with a high prevalence of late recurrence of MR. The valvular procedure alone could be insufficient to treat ischemic MR in terms of long-term survival and the prevention of recurrence because ischemic MR is primarily a ventricular disorder. Thus, recent studies have focused on alternative procedures that target the primary cause of ischemic MR, the papillary muscles and left ventricle. We believe that the appropriate selection of surgical procedures among valvular, subvalvular, and even ventricular ones, considering the severity of LV remodeling for each patient would be more beneficial. Here we review recent studies featuring various surgical approaches to ischemic MR, especially with submitral procedures.

Abstract
OBJECTIVE A hypothesis on left ventricular aneurysms states that there is better preservation of contractile myocardium when the aneurysm geometry is rectangular as opposed to circular. Pre-surgical planning of surgical ventricular restoration was performed on the basis of this hypothesis. METHODS The intraventricular patch used to exclude scarred or aneurysmal myocardium remains akinetic, hence it was used to define aneurysm geometry as circular or rectangular. Hausdorff distance analysis was carried out by mathematical computational methods on the baseline cardiac magnetic resonance images of 5 patients. RESULTS The mean Hausdorff distance for the full range of frequencies was significantly greater after endoventricular linear patch plasty (0.474 ± 0.190 vs. 0.722 ± 0.221 mm, p = 0.047), whereas after endoventricular circular patch plasty, the difference was not significant (0.474 ± 0.190 vs. 0.594 ± 0.193, p = 0.175). The mean Hausdorff distance <0.5 mm was also significantly greater after endoventricular linear patch plasty than after endoventricular circular patch plasty: 0.258 ± 0.03 mm at baseline vs. 0.40 ± 0.16 mm after linear patch plasty (p = 0.039) and 0.258 ± 0.03 vs. 0.32 ± 0.10 mm (p = 0.130) after circular patch plasty. CONCLUSIONS In-silico technology using the Hausdorff distance enables pre-surgical planning and optimization of the technique for surgical ventricular restoration.

Abstract
BACKGROUND Left ventricle (LV) remodeling after anterior wall myocardial infarction leads to increased LV volumes, myocardial stress, and, ultimately, heart failure (HF). Patients have high morbidity and mortality risk, and treatment remains limited. Percutaneous ventricular restoration (PVR) therapy using the Parachute device, a fluoropolymer membrane stretched over a nitinol conical frame, is a novel approach to partition off the damaged myocardium. In the European and United States PARACHUTE feasibility trials, the observed rates of death or rehospitalization for HF were <17% at 12 months. These data compare favorably with historical data and support the need of a randomized trial to determine the clinical efficacy of PVR on outcomes for patients with ischemic HF. OBJECTIVE To determine the safety and efficacy of PVR utilizing a LV partitioning device, Parachute, in a randomized clinical trial compared with optimal medical therapy. METHODS This US pivotal trial is approved by the Food and Drug Administration (ClinicalTrials.gov Identifier: NCT01286116) and will randomly assign (1:1) 478 patients with New York Heart Association class III-IV ischemic HF, akinetic or dyskinetic LV wall abnormality, and ejection fraction between 15% and 35% to optimal medical therapy (control) versus Parachute device implantation in approximately 65 hospitals. The primary endpoint is death or rehospitalization for worsening HF. Sample size calculation assumes constant hazards and follow-up ≥12 months using an event-driven trial design. CONCLUSIONS We reported the rational and design of the first multicenter randomized trial to test the efficacy of PVR using the Parachute device to treat patients with ischemic HF and dilated LV.

Abstract
OBJECTIVES Surgical ventricular reconstruction (SVR) for patients with severe left ventricular (LV) remodelling due to ischaemic cardiomyopathy is still controversial, because the Surgical Treatment for Ischaemic Heart Failure (STICH) trial demonstrated that SVR not only has no beneficial effect on survival compared with coronary artery bypass grafting (CABG) alone, but also is worse for those with a larger LV. Therefore, we assessed the impact of LV remodelling on the outcomes after SVR for ischaemic cardiomyopathy in Japan, using Di Donato's LV shape classification. METHODS From 2000 to 2010, 627 patients underwent SVR for ischaemic heart failure in 11 Japanese hospitals. To assess the patients with an LV ejection fraction (LVEF) of ≤ 35% like the STICH trial, considering the severity of LV remodelling, the patients with a preoperative LVEF of >35%, no preoperative LV volume assessment and no preoperative LV shape classification were excluded. Finally, 323 patients were selected as the study subjects. The LV shape was divided into three types according to Di Donato's classification. Types 1 and 3 indicate the aneurysmal and globally akinetic LV, respectively. Type 2 is the intermediate shape. RESULTS Type 1, 2 and 3 LV shapes were observed in 85 (26%), 104 (32%) and 134 (42%) of the patients, respectively. The preoperative LV volume and diameter increased if the LV became more akinetic (Type 3 > 2 > 1, P < 0.001). LVEF was lower in those with more akinetic LV (P = 0.002). The preoperative LV end-diastolic volume index and LVEF in Type 3 patients were 133 ± 47 ml/m(2) and 22 ± 7%, respectively. Mitral valve repair was more frequently performed for patients with the Type 3 LV shape (65%) than for the others (P < 0.001). The hospital mortality rates were 2.4, 2.9 and 7.4% for Type 1, 2 and 3 patients, respectively (P = 0.16). Kaplan-Meier analysis demonstrated no significant difference in mortality among the three groups (log-rank P = 0.37). The 5-year survival rates were 81, 70 and 73% for Type 1, 2 and 3 patients, respectively. CONCLUSIONS The severity of LV remodelling did not affect survival after SVR plus CABG. The results of SVR were acceptable even for those with globally akinetic LV due to ischaemic cardiomyopathy.

Abstract
At a recent in-house meeting at the European Association for Cardiothoracic Surgery (EACTS) headquarters in Windsor, the Chairs of the four domains were asked by the President to present their perception of the next 5 years in their respective domains. This review represents a distillation of our discussions on adult cardiac surgery. Advances in technology and imaging are having a radical effect on the working lives of surgeons. In clinical practice, the growth of heart teams and the breaking down of artificial barriers between specialities are altering the way we practice for the better. We see the development of hybrid approaches to many areas such as coronary artery surgery and operations on the thoracic aorta. These changes require careful analysis to ensure that they produce better outcomes that are also cost-effective. All health-care systems are at breaking point, and it is our responsibility to harness new technology to benefit our patients. This is all part of placing the patient at the centre of our activities. Hence, we see the involvement of patients in the design and analysis of clinical trials, which also require great mutual trust and cooperation between surgeons in different countries. Because of the dramatic changes in the pattern of working, we have had to alter our patterns of training and education, and we will continue to make significant innovations in the future. These are exciting challenges that will keep us all busy for the next 5 years at least.

Abstract
Heart failure (HF) is an emerging epidemic affecting 15 million people in the USA and Europe. HF-related mortality was unchanged between 1995 and 2009, despite a decrease in the incidence of cardiovascular disease. Conventional explanations include an aging population and improved treatment of acute myocardial infarction and HF. An adverse relationship between structure and function is the central theme in patients with systolic dysfunction. The normal elliptical ventricular shape becomes spherical in ischemic, valvular, and nonischemic dilated cardiomyopathy. Therapeutic decisions should be made on the basis of ventricular volume rather than ejection fraction. When left ventricular end-systolic volume index exceeds 60 ml/m², medical therapy, CABG surgery, and mitral repair have limited benefit. This form-function relationship can be corrected by surgical ventricular restoration (SVR), which returns the ventricle to a normal volume and shape. Consistent early and late benefits in the treatment of ischemic dilated cardiomyopathy with SVR have been reported in >5,000 patients from various international centers. The prospective, randomized STICH trial did not confirm these findings and the reasons for this discrepancy are examined in detail. Future surgical options for SVR in nonischemic and valvular dilated cardiomyopathy, and its integration with left ventricular assist devices and cell therapy, are described.
