Abstract
There is no consensus regarding mitral valve management during surgical ventricular restoration (SVR) for ischemic cardiomyopathy. We compared the impact of SVR with mitral valve repair (MVr) vs replacement (MVR) on postoperative outcomes and long-term survival in ischemic cardiomyopathy and mitral regurgitation patients. This study included 112 patients who underwent SVR from 2009 to 2018 with MVr (n = 75) or MVR (n = 37). Patients who had MVR had higher Euro SCORE II, dyspnea class, a lower ejection fraction, higher pulmonary artery systolic pressure, higher grade of preoperative mitral and tricuspid regurgitation, and higher end-diastolic and end-systolic diameters. Intra-aortic balloon pump was more commonly used in patients with MVR. Hospital mortality occurred in 7 (9.33%) patients in the MVr group vs 3 (8.11%) in the MVR group (P > .99). Freedom from rehospitalization at 1, 5, and 7 years was 87%, 76%, and 70% in the MVr group and 83%, 61%, and 52% in the MVR group (P = .191). Survival at 1, 5, and 7 years was 88%, 78%, and 74% in the MVr group and 88%, 56%, and 56% in the MVR group (P = .027). Adjusted survival did not differ between groups.MVr or MVR are valid options in patients undergoing SVR, with good long-term outcomes.

Abstract
OBJECTIVE The left ventricle remodels from an ellipsoidal/conical shape to a spherical shape after a myocardial infarction. The spherical ventricle is inefficient as a pumping chamber, has higher wall stresses, and can lead to congestive heart failure. We sought to investigate if restoring physiological ventricular shape with a beating heart implant improves pump function. METHODS Rats were induced with a myocardial infarction, developing left ventricular dilatation and dysfunction, and becoming spherical over 3 weeks. Thereafter, they were randomized to undergo left ventricular reshaping with a beating heart implant (n = 19) or continue follow-up without an implant (n = 19). Biweekly echocardiography was performed until 12 weeks, with half the rats euthanized at 6 weeks and remaining at 12 weeks. At termination, invasive hemodynamic parameters and histopathology were performed. RESULTS At 3 weeks after the infarction, rats had a 22% fall in ejection fraction, 31% rise in end diastolic volume, and 23% rise in sphericity. Transventricular implant reshaping reduced the volume by 12.6% and sphericity by 21%, restoring physiologic ventricular shape and wall stress. Over the 12-week follow-up, pump function improved significantly with better ventricular-vascular coupling in the reshaped hearts. In this group, cardiomyocyte cross-section area was higher and the cells were less elongated. CONCLUSIONS Reshaping a postinfarction, failing left ventricle to restore its physiological conical shape significantly improves long-term pump function.

Front Cardiovasc Med 2022; 9:763073.

Abstract
Background Surgical ventricular restoration (SVR) leads to functional improvement by volume reduction and restoration of left ventricular (LV) geometry. Our purpose was to refine the planning for SVR using cardiac computed tomography (CCT). Methods The possibility to anticipate the postoperative residual LV volume was assessed using CCT in 205 patients undergoing SVR combined with coronary artery bypass grafting (77%), mitral valve repair/replacement (19%) and LV thrombectomy (19%). The potential of CCT to guide the procedure was evaluated. Additionally, the predictive value of CCT characteristics on survival was addressed. Results 30-day, 1- and 5-year survival was 92.6, 82.7, and 72.1%, respectively, with a marked reduction of NYHA class III-IV quota after surgery (95.1% vs. 20.5% in the follow-up). Both pre- and postoperative LV end-systolic volume index (LVESVI) were predictive of all defined endpoints according to the following tertiles: preoperative: <74 ml/m2, 74–114 ml/m2 and >114 ml/m2; postoperative: <58 ml/m2, 58–82 ml/m2 and >82 ml/m2. On average, a 50 ml/m2 increase of preoperative LVESVI was associated with a 35% higher hazard of death (p = 0.043). Aneurysms limited to seven antero-apical segments (1–7) were associated with a lower death risk (n = 60, HR 0.52, CI 0.28–0.96, p = 0.038). LVESVI predicted by CCT was found to correlate significantly with effectively achieved LVESVI (r = 0.87 and r = 0.88, respectively, p < 0.0001). Conclusions CCT-guided SVR can be performed with good mid-term survival and significant improvement in HF severity. CCT-based assessment of achievable postoperative LV volume helps estimate the probability of therapeutic success in individual patients.

Predictive Value of Two-Dimensional Speckle-Tracking Echocardiography in Patients Undergoing Surgical Ventricular Restoration. Front Cardiovasc Med 2022; 9:824467.

Abstract
Objectives Parameters of left ventricular (LV) mechanics, obtained from speckle-tracking echocardiography (STE), were found to be of prognostic value in patients with heart failure and those who underwent cardiac surgery. This study aimed to assess the value of STE in patients scheduled to undergo surgical ventricular restoration (SVR). Methods A total of 158 consecutive patients with baseline STE who underwent SVR due to an LV anteroapical aneurysm were included in the analysis. Preoperative longitudinal STE parameters were evaluated for their association with an outcome, defined as all-cause mortality, LV assist device implantation, or heart transplantation. The echocardiographic follow-up to assess the change in the regional function of the segments remote from the aneurysm was performed in 43 patients at a median of 10 months [interquartile range (IQR): 6–12.7 months] after SVR. Results During a median follow-up of 5.1 years (IQR: 1.6–8.7 years), events occurred in 68 patients (48%). Less impaired mean basal end-systolic longitudinal strain (BLS) with a cutoff value ≤ −10.1 % demonstrated a strong association with event-free survival, also in patients with an LV shape corresponding to an intermediate shape between aneurysmal and globally akinetic. Initially hypo- or akinetic basal segments with preoperative end-systolic strain ≤ −7.8% showed a greater improvement in wall motion at the short-term follow up. Conclusion Patients with less impaired preoperative BLS exhibited a better event-free survival after SVR, also those with severe LV remodeling. The preserved preoperative segmental longitudinal strain was associated with a greater improvement in regional wall motion after SVR. BLS assessment may play a predictive role in patients with an LV anteroapical aneurysm who are scheduled to undergo SVR.

Objective To report our center’s experience in the surgical treatment of ventricular
reconstruction, an effective and efficient technique that allows patients
with end-stage heart failure of ischemic etiology to have clinical
improvement and increased survival. Methods Observational, clinical-surgical, sequential, retrospective study. Patients
with ischemic cardiomyopathy and left ventricular aneurysm were attended at
the Heart Failure, Ventricular Dysfunction and Cardiac Transplant outpatient
clinic of the Dante Pazzanese Cardiology Institute, from January 2010 to
December 2016. Data from 34 patients were collected, including systemic
arterial hypertension, ejection fraction, New York Heart Association (NYHA)
functional classification (FC), European System for Cardiac Operative Risk
Evaluation (EuroSCORE) II value, Society of Thoracic Surgeons (STS) score,
ventricular reconstruction technique, and survival. Results Overall mortality of 14.7%, with hospital admission being 8.82% and late
death being 5.88%. Total survival rate at five years of 85.3%. In the
preoperative phase, NYHA FC was Class I in five patients, II in 18, III in
eight, and IV in three vs. NYHA FC Class I in 17 patients,
II in eight, III in six, and IV in three, in the postoperative period.
EuroSCORE II mean value was 6.29, P≤0.01; hazard
ratio (HR) 1.16 (95% confidence interval [CI] 1.02-1.31). STS
mortality/morbidity score mean value was 18.14,
P≤0.004; HR 1.19 (95% CI 1.05-1.33). Surgical
techniques showed no difference in survival among Dor 81%
vs. Jatene 91.7%. Conclusion Surgical treatment of left ventricular reconstruction in candidates for heart
transplantation is effective, efficient, and safe, providing adequate
survival.

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.
