RESUMO
BACKGROUND: Pulmonary thromboendarterectomy (PTE) is a curative procedure for chronic thromboembolic pulmonary hypertension (CTEPH). Right ventricular free wall strain (RV FWS) and right atrial strain (RAS) are not well studied in a CTEPH population. We sought to determine temporal trends in RAS and RV FWS in patients post-PTE. METHODS: 28 patients undergoing PTE for CTEPH were prospectively enrolled in a surgical database. Comprehensive echocardiographic assessment of the right heart was performed including RV FWS, right atrial volume, and the three components of RAS: reservoir, conduit, and booster strain. RESULTS: Patients undergoing PTE demonstrated improvement in NYHA functional class (P < 0.001). Hemodynamic assessment showed improvement in mean pulmonary artery pressure from 49.7 ± 8.5 mm Hg to 23.9 ± 6.5 mm Hg (P < 0.001) and pulmonary vascular resistance decreased from 7.8 ± 3.2 wu to 2.4 ± 1.3 wu (P < 0.001). Tricuspid annular plane systolic excursion (TAPSE) and lateral S` declined immediately post-op. RV FWS improved from -14.4 ± 4% to -19 ± 3.4% post-op and -21.2 ± 4.7% at long-term follow-up (P < 0.001). Improvement in RV FWS post-op was driven primarily by increases in the apical and mid segments. RA volume declined significantly during the study period. RA reservoir and conduit strain improved after PTE. CONCLUSION: Patients undergoing PTE for CTEPH had significant improvement in right heart hemodynamics immediately post-op. Traditional echo metrics of RV performance including TAPSE and lateral S` did not improve. RV FWS improved, which was driven by changes in the apical and mid segments. This highlights that RV FWS is a viable and useful metric to follow in CTEPH patients post-PTE.

Objective: Acupuncture is an effective treatment for arrythmias and postoperative symptoms but has not been investigated after cardiac surgery. Acupuncture After Heart Surgery is a prospective, randomized, controlled pilot trial of daily inpatient acupuncture or standard care after valve surgery with the primary end point being feasibility and secondary end points being reduction in postoperative atrial fibrillation incidence and postoperative symptoms. Methods: A total of 100 patients without a history of atrial fibrillation underwent primary valve surgery via sternotomy and randomized 1:1 to acupuncture (51) or standard care (49). The acupuncture group received daily inpatient sessions starting on postoperative day 1. Postoperative symptoms (pain, nausea, stress, anxiety) were assessed once daily in the standard care group and before/after daily intervention in the acupuncture group. The groups were comparable except for age (acupuncture: 55.6 ± 11.4 years, standard care: 61.0 ± 9.3 years; P = .01). Results: The Acupuncture After Heart Surgery pilot trial met primary and secondary end points. There were no adverse events. An average of 3.8 (±1.1) acupuncture sessions were delivered per patient during a mean hospital stay of 4.6 days (±1.3). Acupuncture was associated with a reduction in pain, nausea, stress, and anxiety after each session (P < .0001), and patients receiving acupuncture had reduced postoperative stress and anxiety across admission compared with standard care (P = .049 and P = .036, respectively). Acupuncture was associated with reduced postoperative atrial fibrillation incidence (acupuncture: 7 [13.7%], standard care: 16 [32.7%]; P = .028), fewer discharges on amiodarone (acupuncture: 5 [9.8%], standard care: 13 [26.5%]; P = .03), and fewer hours in the intensive care unit (acupuncture: 30.3 ± 10.0, standard care: 37.0 ± 22.5; P = .057). Conclusions: Acupuncture after valve surgery is feasible, is well tolerated, and has clinical benefit. The reduction noted in postoperative atrial fibrillation incidence will inform larger trials designed to further investigate the impact of acupuncture on postoperative atrial fibrillation and medical outcomes.
RESUMO
OBJECTIVES: Concomitant atrial fibrillation often goes untreated because of surgeon concerns regarding lesion set complexity and pump times. We describe a new cryoablation procedure to address this. METHODS: From June 2013 to March 2021, a modified CryoMaze III procedure was used using 3 left atrial ± 3 right atrial cryo-applications creating the key lesions of the Cox Maze III procedure. Since 2018, 3-minute cryo-lesions were used for the left atrial box lesion for total cryoablation times of 8 minutes for the left atrium ± 6 minutes for the right atrium. By using propensity matching, patients undergoing mitral valve surgery with no atrial fibrillation history were compared with CryoMaze III-treated patients. RESULTS: A total of 100% of the 277 patients with atrial fibrillation requiring mitral valve surgery ± other procedures received the modified CryoMaze III procedure. After propensity score matching (n = 161 each group), the modified CryoMaze III group had mean crossclamp and bypass times 10.5 and 13.4 minutes longer than the control group, respectively. There were no significant differences in 30-day mortality, morbidity, pacemaker use, renal dysfunction, or late survival between groups, but there were less postoperative strokes in the CryoMaze III group. Freedom from atrial fibrillation off antiarrhythmics was 77% (mean follow-up of 3.0 ± 2.1 years). At 12 months, freedom from atrial fibrillation off antiarrhythmics was 90% for the 3-minute ablation group. Late survival was similar to age- and sex-matched Centers for Disease Control and Prevention controls. CONCLUSIONS: The modified CryoMaze III technique is efficient, safe, and effective. Education of the surgical community regarding the late benefits of ablation and the simplicity of this new technique should improve adoption of the Class I Guidelines to treat concomitant atrial fibrillation.
RESUMO
BACKGROUND: Restoring health-related quality of life (HRQOL) is a therapeutic goal for older patients with advanced heart failure. We aimed to describe change in HRQOL in older patients (60-80 years) awaiting heart transplantation (HT) with or without pretransplant mechanical circulatory support (MCS) or scheduled for long-term MCS, if ineligible for HT, from before to 6 months after these surgeries and identify factors associated with change. METHODS: Patients from 13 US sites completed the EuroQol 5-dimension 3L questionnaire and Kansas City Cardiomyopathy Questionnaire-12 at baseline and 3 and 6 months after HT or long-term MCS. Analyses included univariate comparisons and multivariable linear regression. RESULTS: Among 305 participants (cohort mean age=66.2±4.7 years, 78% male, 84% White, 55% New York Heart Association class IV), 161 underwent HT (n=68 with and n=93 without pretransplant MCS), and 144 received long-term MCS. From baseline to 3 months, EuroQol 5-dimension visual analog scale scores improved in HT patients without pretransplant MCS (54.5±24.3 versus 75.9±16.0, P<0.001) and long-term MCS patients (45.7±22.9 versus 66.2± 20.9, P <0.001); while Kansas City Cardiomyopathy Questionnaire-12 overall summary scores improved in all 3 groups (HT without pretransplant MCS: 47.2±20.9 versus 77.4±20.1, P <0.001; long-term MCS: 35.3±20.2 versus 58.6±22.0, P <0.001; and HT with pretransplant MCS: 58.3±23.6 versus 72.1±23.5, P=0.002). No further HRQOL improvement was found from 3 to 6 months. Factors most significantly associated with change in HRQOL, baseline 3 months, were right heart failure and 3-month New York Heart Association class, and 3 to 6 months, were 6-month New York Heart Association class and major bleeding. CONCLUSIONS: In older heart failure patients, HRQOL improved from before to early after HT and long-term MCS. At 6 postoperative months, HRQOL of long-term MCS patients was lower than one or both HT groups. Understanding change in HRQOL from before to early after these surgeries may enhance decision-making and guide patient care. REGISTRATION: URL: https://www.

Background There is a paucity of research describing health-related quality of life (HRQOL) in older adults considered for advanced heart failure surgical therapies. Using data from our SUSTAIN-IT (Sustaining Quality of Life of the Aged: Heart Transplant or Mechanical Support) study, we aimed to compare HRQOL among 3 groups of older (60-80 years) patients with heart failure before heart transplantation (HT) or long-term mechanical circulatory support (MCS) and identify factors associated with HRQOL: (1) HT candidates with MCS, (2) HT candidates without MCS, or (3) candidates ineligible for HT and scheduled for long-term MCS. Methods and Results Patients from 13 US sites completed assessments, including self-reported measures of HRQOL (EuroQol-5 Dimension Questionnaire, Kansas City Cardiomyopathy Questionnaire-12), depressive symptoms (Personal Health Questionnaire-8), anxiety (State-Trait Anxiety Inventory-state form), cognitive status (Montreal Cognitive Assessment), and performance-based measures (6-minute walk test and 5-m gait speed). Analyses included ANOVA, χ2 tests, Fisher's exact tests, and linear regression. The sample included 393 patients; the majority of patients were White men and married. Long-term MCS candidates (n=154) were significantly older and had more comorbidities and a higher New York Heart Association class than HT candidates with MCS (n=118) and HT candidates without MCS (n=121). Long-term MCS candidates had worse HRQOL than HT candidates with and without MCS (EQ-5D visual analog scale scores, 46±23 versus 68±18 versus 54±23 [P<0.001] and Kansas City Cardiomyopathy Questionnaire-12 overall summary scores, 35±21 versus 60±21 versus 49±22 [P<0.001], respectively). In multivariable analyses, lower 6-minute walk distance, higher New York Heart Association class, depressive symptoms, and not being an HT candidate with MCS were significantly associated with worse overall HRQOL. Conclusions Our findings demonstrate important differences in overall and domain-specific HRQOL of older patients with heart failure before HT or long-term MCS. Understanding HRQOL differences may guide decisions toward more appropriate and personalized advanced heart failure therapies.

BACKGROUND: We sought to compare change over time (baseline to 2 y) in health-related quality of life (HRQOL) between older (60-80 y) patients awaiting heart transplantation (HT) with mechanical circulatory support (MCS) versus without MCS and their caregivers and caregiver burden. METHODS: This study was conducted at 13 United States sites. Patient HRQOL was examined using the EuroQol 5-dimensional questionnaire (EQ-5D-3L) and Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12). Caregiver measures included the EQ-5D-3L and Oberst Caregiving Burden Scale, measuring time on task and difficulty. Analyses included analysis of variance, χ2, and linear regression. RESULTS: We enrolled 239 HT candidates (n = 118 with MCS and n = 121 without MCS) and 193 caregivers (n = 92 for candidates with MCS and n = 101 for candidates without MCS). Baseline differences in HRQOL were observed between HT candidates with and without MCS: EQ-5D-3L visual analog scale (VAS) score (67.7 ± 17.6 versus 54.1 ± 23.3, P < 0.001) and KCCQ-12 overall summary score (59.9 ± 21.0 versus 48.9 ± 21.6, P < 0.001), respectively. HT candidates with MCS had significantly higher EQ-5D-3L VAS scores and KCCQ-12 overall summary score across time versus without MCS. Baseline EQ-5D-3L VAS scores did not differ significantly between caregivers of HT candidates with and without MCS (84.6 ± 12.9 versus 84.3 ± 14.4, P = 0.9), respectively, nor were there significant between-group differences over time. Caregivers for HT candidates with MCS reported more task difficulty (range: 1 = not difficult to 5 = extremely difficult) versus caregivers for those without MCS at baseline (1.4 ± 0.5 versus 1.2 ± 0.3, P = 0.004) and over time. CONCLUSIONS: Understanding differences in HRQOL and caregiver burden among older HT candidates with and without MCS and their caregivers may inform strategies to enhance HRQOL and reduce burden.
