Chagas disease in Virgem da Lapa, Minas Gerais, Brazil: left ventricle aneurysm and the risk of death in the 24-year interval.

BACKGROUND: Left ventricular aneurysm (LVA) is indicator of high morbidity in Chagas' disease. A cross-sectional study performed identified LVA in 18.8% of the chronic chagasic patients (CCP). OBJECTIVE: Determine the risk of death of patients with chronic chagasic cardiopathy (CCC) and LVA in 24-year interval. MATERIAL AND METHODS: In 1995 a cohort of 298 CCP was evaluated by anamnesis, physical examination, EKG and ECHO and classified in groups: G0 = 86 without cardiopathy; G1 = 156 with cardiopathy without LVA and G2 = 56 with cardiopathy and LVA. 38 patients of G0 and G1 used benznidazole. Information about the deaths was obtained in the notary, death certificates, hospital records and family members. FINDINGS: Were registered 113 deaths (37.9%): 107 (35.9%) attributed to cardiopathy and 6 (2.0%) to other causes (p < 0.05). Amongst these 107 deaths, 10 (11.6%) occurred in G0; 49 (31.4%) occurred in G1 and 48 (85.7%) occurred in G2 (p < 0.05). The risk of death was 2.7 and 7.4 times significantly higher in G2, than in G1 and G0, respectively. CONCLUSION: Chronic chagasic patients with LVA and ejection fraction < 45% have a higher risk of death than those without.

The Pacopexy procedure for left ventricular aneurysm: a 10-year clinical experience.

PURPOSE: To evaluate our 10-year clinical experience of performing the Pacopexy procedure for left ventricular aneurysm (LVA). METHODS: Between January, 1998 and November, 2015, a cohort of 92 patients with LVA underwent surgery to reshape the left ventricle. Fifty-seven patients underwent the Dor procedure and 35 underwent the Pacopexy procedure to emphasize the conical shape, whereby patch placement followed an oblique trajectory between the left ventricular apex and the septum below the aortic valve. RESULTS: The early-mortality rate was 4.34% (4/92; n = 2 in each group). The 10-year survival rate was 70.4 ± 7.9% in the Pacopexy group vs 41.7 ± 7.2% in the Dor group (p < 0.05), and the rate of freedom from hospital re-admission for heart failure (HF) or cardiac death was 60.0 ± 8.6% vs 28.8 ± 6.8%, respectively (p < 0.05). The Dor procedure and left ventricular end systolic volume index (LVESVI) ≥ 60 ml/m2 were strongly and significantly associated with long-term mortality and hospital re-admission for HF. CONCLUSIONS: The Pacopexy procedure is a reproducible surgical option for the treatment of LVA. The improved configuration achieved by the Pacopexy procedure has resulted in good long-term survival and a high degree of freedom from re-admission for HF in patients with advanced LVA.

Left Ventricular Reconstruction Surgery in Candidates for Heart Transplantation.

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.

Left ventricular aneurysm repair: off-pump linear plication versus on-pump patch plasty

Abstract Objective: The study aimed to compare the clinical outcomes of simplified linear plication and classic patch plasty in patients with left ventricular aneurysm (LVA). Methods: We retrospectively reviewed 282 patients undergoing LVA repair between 2006 and 2016. After propensity score matching, 45 pairs of patients receiving LVA surgery were divided into either a patch group (on-pump endoventricular patch plasty) or a plication group (off-pump linear plication). Then, their early surgical outcomes and long-term survival were compared in two matched groups. Results: The heart function improvement at discharge was similar in the two matched groups, while patients in the patch group more commonly suffered from low cardiac output syndrome (P=0.042) with higher proportion of intra-aortic balloon pumping assistance (P=0.034) than patients in the plication group. Compared with patients in the patch group, the patients in the plication group had shorter recovery times, regarding to mechanical ventilation, intensive care unit stay, and hospital stay (P<0.001, P<0.001, and P=0.001, respectively). No significant difference was found in the long-term survival (P=0.62). Conclusions: Off-pump linear plication presented acceptable results in terms of early outcomes and long-term survival. For high-risk patients, the simplified LVA repair technique may be an option.

For high-risk patients, the simplified LVA repair technique may be an option.

Treatment outcomes and therapeutic evaluations of patients with left ventricular aneurysm.

OBJECTIVE: This study was performed to analyze and compare the efficacy of three treatment methods for left ventricular aneurysm (LVA): coronary artery bypass grafting (CABG) combined with left ventricular resection, drug treatment, and percutaneous coronary intervention (PCI). METHODS: In total, 183 patients with LVA from Fuwai Hospital were divided into three groups according to the treatment method: 51 patients underwent left ventricular resection combined with CABG (CABG-resection group), 65 underwent drug treatment (drug group), and 67 underwent PCI (PCI group). The clinical characteristics and survival rates of the patients were compared among the three groups. RESULTS: The patients' basic data and medical history were analyzed. The postoperative left ventricular end-diastolic dimension (LVEDD) and left ventricular ejection fraction (LVEF) were significantly higher than those before surgery, indicating that the left ventricular function markedly improved after the operation. CONCLUSION: Surgery is recommended as the first treatment option for LVA, and conservative therapy can be considered for selected patients. Although the difference was not statistically significant, CABG with left ventricular resection was associated with a better LVEF and LVEDD and higher survival and non-recurrence rates than PCI or drug treatment.

Application of Circular Patch Plasty (Dor Procedure) or Linear Repair Techniques in the Treatment of Left Ventricular Aneurysms.

OBJECTIVE: The aim of this study was to evaluate early clinical outcomes and echocardiographic measurements of the left ventricle in patients who underwent left ventricular aneurysm repair using two different techniques associated to myocardial revascularization. METHODS: Eighty-nine patients (74 males, 15 females; mean age 58±8.4 years; range: 41 to 80 years) underwent post-infarction left ventricular aneurysm repair and myocardial revascularization performed between 1996 and 2016. Ventricular reconstruction was performed using endoventricular circular patch plasty (Dor procedure) (n=48; group A) or linear repair technique (n=41; group B). RESULTS: Multi-vessel disease in 55 (61.7%) and isolated left anterior descending (LAD) disease in 34 (38.2%) patients were identified. Five (5.6%) patients underwent aneurysmectomy alone, while the remaining 84 (94.3%) patients had aneurysmectomy with bypass. The mean number of grafts per patient was 2.1±1.2 with the Dor procedure and 2.9±1.3 with the linear repair technique. In-hospital mortality occurred in 4.1% and 7.3% in group A and group B, respectively (P>0.05). CONCLUSION: The results of our study demonstrate that post-infarction left ventricular aneurysm repair can be performed with both techniques with acceptable surgical risk and with satisfactory hemodynamic improvement.

Recurrent Cardiovascular Events in Survivors of Myocardial Infarction With ST-Segment Elevation (from the AMI-QUEBEC Study).

The characteristics and predictors of long-term recurrent ischemic cardiovascular events (RICEs) after myocardial infarction with ST-segment elevation (STEMI) have not yet been clarified. We aimed to characterize the 10-year incidence, types, and predictors of RICE. We obtained 10-year follow-up of STEMI survivors at 17 Quebec hospitals in Canada (the AMI-QUEBEC Study) in 2003. There were 858 patients; mean age was 60 years and 73% were male. The majority of patients receive reperfusion therapy; 53.3% and 39.2% of patients received primary percutaneous coronary intervention (PCI) and fibrinolytic therapy, respectively. Seventy-five percent of patients underwent in-hospital PCI (elective, rescue, and primary). At 10 years, 42% of patients suffered a RICE, with most RICEs (88%) caused by recurrent cardiac ischemia. The risk of RICE was the highest during the first year (23.5 per patient-year). At 10 years, the all-cause mortality was 19.3%, with 1/3 of deaths being RICE-related. Previous cardiovascular event, heart failure during the index STEMI hospitalization, discharge prescription of calcium blocker increased the risk of RICE by almost twofold. Each point increase in TIMI (Thrombolysis In Myocardial Infarction) score augmented the risk of RICE by 6%, whereas discharge prescription of dual antiplatelets reduced the risk of RICE by 23%. Our findings suggested that survivors of STEMI remain at high long-term risk of RICE despite high rate of reperfusion therapy and in-hospital PCI. Patients with previous cardiovascular event, in-hospital heart failure, and high TIMI score were particularly susceptible to RICE. Future studies are needed to confirm the impacts of calcium blocker and dual antiplatelets on long-term risk of RICE.

Cardiac death in patients with left ventricular aneurysm, remodeling and myocardial viability by gated 99mTc-MIBI SPECT and gated 18F-FDG PET.

(1) To evaluate the prognostic value of LV remodeling parameters in patients with LV aneurysm by gated SPECT (GSPECT), gated PET (GPET) and CMR; (2) to evaluate the impact of myocardial viability and LV remodeling on the long-term cardiac survival in patients with LV aneurysm. One hundred and twenty-six consecutive patients underwent GPET, GSPECT and CMR within two weeks, with a mean follow-up of 3.9 ± 1.5 years. End-diastolic volume (EDV, mL) and end-systolic volume (ESV, mL) measured by GPET, GSPECT and CMR and corrected for BSA; EDVI and ESVI were calculated. Patients were divided into three groups by aneurysmal viability [mismatch score (MMS) of aneurysm ≥2.0] and LV remodeling (ESVI by GPET > 60 mL/m2). Group 1 (Viability -, LV remodeling -); Group 2 (Viability -, LV remodeling +) and Group 3 (Viability +, LV remodeling -/+). ESVI by GPET, MMS of aneurysm and summed rest score of aneurysm by multivariate regression analysis; as well as ESVI by GPET (HR 1.024, 95% CI 1.011-1.037, p = .0004), MMS of aneurysm (HR 1.284, 95% CI 1.051-1.577, p = .015) by interaction analysis were approved being independent predictors for cardiac death (p < .05). The long-term cardiac survival was significantly improved by revascularization in comparison with medical therapy in Group3 (p < .01), but did not significantly differ between Groups 1 and 2. ESVI by GPET showed a significant positive predictive value for cardiac death. Patients with viable myocardial aneurysm were most likely at increased risk for cardiac death and coronary revascularization was significantly associated with improved long-term cardiac survival. In contrast, the long-term cardiac survival of patients without LV remodeling and without aneurysmal viability was promising and, thus, could be treated by medical therapy.

Hypertrophic Cardiomyopathy With Left Ventricular Apical Aneurysm: Implications for Risk Stratification and Management.

BACKGROUND: A previously under-recognized subset of hypertrophic cardiomyopathy (HCM) patients with left ventricular (LV) apical aneurysms is being identified with increasing frequency. However, risks associated with this subgroup are unknown. OBJECTIVES: The authors aimed to clarify clinical course and prognosis of a large cohort of HCM patients with LV apical aneurysms over long-term follow-up. METHODS: The authors retrospectively analyzed 1,940 consecutive HCM patients at 2 centers, 93 of which (4.8%) were identified with LV apical aneurysms; mean age was 56 ± 13 years, and 69% were male. RESULTS: Over 4.4 ± 3.2 years, 3 of the 93 patients with LV apical aneurysms (3%) died suddenly or of heart failure, but 22 (24%) survived with contemporary treatment interventions: 18 experienced appropriate implantable cardioverter-defibrillator discharges, 2 underwent heart transplants, and 2 were resuscitated after cardiac arrest. The sudden death (SD) event rate was 4.7%/year, which includes sudden death, successful resuscitation from cardiac arrest or appropriate ICD interventions triggered by VF or rapid VT. Notably, recurrent monomorphic ventricular tachycardia requiring ≥2 implantable cardioverter-defibrillator shocks occurred in 13 patients, including 6 who underwent successful radiofrequency ablation of the arrhythmic focus without ventricular tachycardia recurrence. Five non-anticoagulated patients experienced nonfatal thromboembolic events (1.1%/year), whereas 13 with apical clots and anticoagulation did not incur embolic events. There was no consistent relationship between aneurysm size and adverse HCM-related events. Rate of HCM-related deaths combined with life-saving aborted disease-related events was 6.4%/year, 3-fold greater than the 2.0%/year event rate in 1,847 HCM patients without aneurysms (p < 0.001). CONCLUSIONS: HCM patients with LV apical aneurysms are at high risk for arrhythmic sudden death and thromboembolic events. Identification of this phenotype expands risk stratification and can lead to effective treatment interventions for potentially life-threatening complications.

The Influence of Apical Aneurysm on Left Ventricular Geometry and Clinical Outcomes: 3-Year Follow-Up Using Echocardiography.

BACKGROUND: Left ventricular apical aneurysm (LVAA) is a serious complication associated with myocardial infarction. However, the effects of a previously formed LVAA on long-term left ventricular (LV) geometry and clinical outcomes have not been fully evaluated. METHODS: From January 2009 to May 2015, we retrospectively identified 70 patients (mean age, 66 ± 12 years; males, 72.9%) with an LVAA due to ischemia. These patients were classified into two groups according to the initial apical conicity ratio (ACR): large LVAA group (ACR ≥ 1.5, n = 40) and small LVAA group (ACR < 1.5, n = 30). An adverse outcome was defined as a composite of fatal arrhythmia, embolic infarction, and readmission due to heart failure. RESULTS: The ACR significantly decreased over the first month and then increased after 1 and 3 years of follow-up. The other examined echocardiographic indexes did not exhibit temporal changes. During the follow-up period (median 1138 days), the large LVAA group experienced a lower event-free survival (P = 0.016). In a multivariate Cox model, the presence of a large LVAA (adjusted hazard ratio [HR] = 2.795, 95% confidence interval [CI] = 1.118-6.986, P = 0.028) and the initial LV ejection fraction (EF) (adjusted HR = 0.964, 95% CI = 0.932-0.997, P = 0.034) were independent predictors of adverse outcomes. CONCLUSIONS: This study demonstrates that LVAAs undergo a dynamic process and that large LVAAs are associated with adverse outcomes. Our results suggest that the ACR could be helpful for predicting adverse outcomes in patients with apical aneurysm.

Left atrial dissection: an almost unknown entity.

Left atrial dissection is an exceedingly rare but potentially fatal complication of cardiac surgery. It is most commonly associated with mitral valve surgery, including both replacement and repair, with a reported incidence rate of 0.16%. However, other cardiac surgical or catheter-based interventional procedures are also known as potential predisposing factors. The time of presentation from the cause of dissection varies extremely, ranging from immediate occurrence up to 20 years later. The dissection forms a large cavity between the endocardium and epicardium of the left atrium, causing obliteration of the left atrial cavity and resultant haemodynamic compromise, which almost always requires immediate surgical intervention. In contrast, left atrial dissection without haemodynamic instability can often be managed non-operatively with satisfactory outcomes. This article reviews this rare but relevant clinical entity to further elucidate the incidence, pathogenesis, clinical course, management and outcome of left atrial dissection.

Left atrial appendage aneurysm: a systematic review of 82 cases.

BACKGROUND: Aneurysm of the left atrial appendage is rare. We sought to systematically review the published literature on left atrial appendage aneurysm (LAAA) to address its demographic features, clinical characteristics, treatment, complications, and outcomes. METHODOLOGY: A systematic electronic search of Medline, PubMed, and EMBASE for case reports, case series, and related articles of LAAA published from 1962 until July 2013 was carried out. Statistical analysis was done using SPSS version 20.0. Logistic Regression Analysis was used to identify the independent predictors of LAAA-related thrombus formation and embolism. RESULTS: Eighty-two cases of LAAA were identified. There was a slight female preponderance and most of the patients presented in their third decades. Palpitation, dyspnea or both were most common clinical symptoms associated with LAAA. Echocardiography was the main diagnostic modality used and the mean size of aneurysm was 7.08 ± 3.03 × 5.75 ± 2.36 cm. Surgical resection of the aneurysm was performed in most patients with favorable results. Systemic embolism and atrial tachyarrhythmias were the two common complications associated with untreated LAAA. Presence of atrial fibrillation/flutter was the only significant predictor of thrombus formation/embolic events. CONCLUSION: Aneurysm of left atrial appendage is rare and often an incidental diagnosis during echocardiography. It is important to recognize this entity since it is associated with cardiovascular morbidity and mortality by predisposing to atrial tachyarrhythmia and thromboembolism. Surgical resection is the standard of treatment in the current literature. Medical management is directed toward the treatment of thromboembolism and atrial tachyarrhythmia.

Clinical impact of diastolic function after surgical ventricular restoration.

OBJECTIVE: The impact of diastolic function on the clinical outcome of surgical ventricular restoration remains controversial. METHODS: 71 patients undergoing surgical ventricular restoration between 1999 and 2012 were investigated. Perioperative echocardiographic parameters were compared, risk factors for deaths and cardiac events were analyzed, and actuarial freedom from death and cardiac events was computed. RESULTS: Preoperatively, the left ventricular end-systolic volume index was 77 ± 40 mL·m(-2) and left ventricular ejection fraction was 33% ± 11%. Postoperatively, left ventricular systolic function was significantly improved (end-systolic volume index 49 ± 31 mL·m(-2), ejection fraction 42.1% ± 11.7%) with a 33.8% ± 21.9% reduction in left ventricular end-systolic volume index. The transmitral filling deceleration time decreased from 198 ± 54 to 150 ± 46 ms, and the ratio of early peak filling velocities increased significantly postoperatively (from 16 ± 10 to 21 ± 17). Freedom from death and cardiac events at 5 years was 78% ± 5% and 64% ± 6%, respectively. Multivariate analyses revealed that age was a significant risk factor for all-cause death, postoperative transmitral inflow pattern for cardiac death, and preoperative mitral regurgitation and postoperative transmitral inflow pattern for cardiac events. CONCLUSION: Despite its positive impact on systolic function, surgical ventricular restoration negatively affects postoperative diastolic function. Postoperative severe diastolic dysfunction may correlate with late mortality and cardiac events.

Right atrial appendage aneurysm: a systematic review.

BACKGROUND: Right atrial appendage aneurysm (RAAA) is rare with fewer than 20 cases reported in the literature. We sought to systematically review the published cases of RAAA in terms of demographics, clinical characteristics, treatment, complications, and outcome. METHODOLOGY: Electronic search for case reports, case series, and related articles published until July 2013 was carried out and clinical data were extracted and analyzed. RESULTS: Seventeen cases of RAAA were identified with equal sex distribution and commonly presenting in the third decades of life. Dyspnea and palpitation were the most common clinical presentations. Echocardiography was the most common diagnostic modality. The mean size of aneurysm was 8.83 ± 4.84 × 6.05 ± 2.99 cm. Most of the patients were treated medically with close follow-up. The mean follow-up period was 10 months. Atrial tachyarrhythmias and heart failure were the most common complications. CONCLUSION: Right atrial appendage aneurysm although rare may be associated with significant morbidity. Surgical resection is indicated in symptomatic patients.

Posterobasal left ventricular aneurysms: surgical treatment and long-term outcomes.

This retrospective study analyzes short- and long-term outcomes in 18 patients who underwent repair of posterobasal left ventricular aneurysm from January 1993 through December 2009. As concomitant procedures, mitral reconstruction was performed in 4 patients, ventricular septal defect repair in 2 patients, and coronary artery bypass grafting in 17 patients. In regard to surgical technique, 10 patients underwent patch repair and 8 underwent closure by linear suture. The in-hospital mortality rate was 11% (2 patients). An intra-aortic balloon pump was placed postoperatively in 1 patient. One patient underwent reoperation for mediastinitis and 2 for bleeding. The 1-, 5-, and 10-year survival rates were 82%, 76%, and 52%, respectively. Posterobasal left ventricular aneurysm repair can be performed with low short-term mortality rates and good long-term outcomes. It must be judged whether a linear repair or patch repair is better, in accordance with aneurysm size and the concomitant operative procedure, if any.
