Abstract
OBJECTIVE Outcome data for patients ≥75 years with hypertrophic obstructive cardiomyopathy (HOCM) undergoing alcohol septal ablation (ASA) are lacking. Therefore, a retrospective single-centre analysis was conducted. METHODS The data of all consecutive ASAs, that were performed at our institution between 1 September 1997 and 31 July 2021 in patients with HOCM with left ventricular outflow tract gradients (LVOTG) ≥50 mm Hg, were collected from patient reports. ASA was performed per institutional standards with 95% ethanol infused into a feasible septal branch. Differences regarding echocardiographic, procedural and clinical parameters at baseline and after 6 months between patients ≥75 years and <75 years were assessed. RESULTS We found 208 ASAs in patients ≥75 years (85.1% female; age 78.0 years (IQR 76.0-80.0)) and 1430 ASAs in patients <75 years (42.0% female; age 56.0 years (IQR 46.0-65.0)). Patients ≥75 years had lower distances in 6 min walk test (baseline: 317.0 m (IQR 242.0-389.0) vs 438.0 m (IQR 353.3-504.0); p<0.0001). Exercise-induced LVOTG calculated at follow-up was lower in patients ≥75 years (29.5 mm Hg (IQR 18.0-54.0) vs 39.5 mm Hg (IQR 23.0-73.8); p=0.0007). There were more high-degree AV blocks after ASA in patients ≥75 years (25.5% vs 13.6%; p<0.0001). The in-hospital mortality did not differ between the groups (age ≥75 years: 1.0%; age <75 years: 0.6%; p=0.6580). CONCLUSION ASA had similar efficacy and intrahospital mortality in patients ≥75 years compared with younger patients. Higher rates of AV block with need for permanent pacemaker implantation were observed in patients ≥75 years of age.

Abstract
Hypertrophic cardiomyopathy (HCM) is known to be the most prevalent genetic cardiac condition. However, there have been limited reports on the diagnosis of HCM accompanied by secondary hypertension and the subsequent systematic therapy. In this case report, we present the case of a 65-year-old male patient who presented with recurring chest discomfort during physical activity, along with refractory hypertension. Cardiac magnetic resonance imaging (MRI) and transthoracic echocardiogram(TTE) revealed the presence of HCM in this individual. Further investigation revealed hypokalemia, elevated aldosterone levels, decreased plasma renin activity, and an aldosterone-to-renin ratio above 30. These findings strongly indicated primary aldosteronism (PA) as an additional condition affecting this patient. Through the utilization of whole exome sequencing, we successfully identified a suspected pathogenic gene TTN as the underlying cause of the patient's condition. The presence of HCM accompanied by secondary hypertension due to PA resulted in significant enlargement of the left ventricle, particularly the ventricular septum. While certain genetic mutations may suggest a potential link to cardiomyopathy development, they cannot definitively establish a direct association between HCM and PA.

Abstract
The progress in the management of hypertrophic cardiomyopathy (HCM) over the last several decades has resulted in great improvements in quality of life and overall survival for HCM patients. Yet, sudden cardiac death (SCD) due to ventricular tachyarrhythmias is among the common causes of HCM-related mortality. SCD risk stratification is a central and often challenging domain in the care of the HCM patient. Distinguishing the individuals most likely to benefit from a primary prevention implantable-cardioverter defibrillator (ICD) from those truly at a low risk of SCD in whom an ICD is not necessary is a nuanced process. Clinicians need to carefully balance the potential benefit and risks of ICDs, particularly in young patients. Because of intense investigations in diverse HCM cohorts globally, two main approaches to SCD risk stratification in HCM have emerged, one based on major SCD risk factors and one based on a mathematically derived risk score. In this overview, we discuss the current state, latest advances and remaining unknowns about established and novel markers of risk of SCD in HCM. We also review how the risk factor- and risk score-based assessments can and should be used in conjunction to enhance rather than contradict each other in facilitating informed ICD decision-making in contemporary clinical practice.

Abstract
OBJECTIVE Echocardiography-guided Percutaneous IntraMyocardial Septal Radiofrequency Ablation (PIMSRA, Liwen procedure) is a novel treatment option for hypertrophic obstructive cardiomyopathy (HOCM). The impact of PIMSRA on myocardial mechanics is unknown. METHODS Between October 2016 and June 2019, PIMSRA and 3-dimentional speckle tracking echocardiography were performed in 82 patients. Echocardiographic imaging, qualitative and quantitative clinical assessment were completed at baseline, immediately postprocedure and 1-year follow-up. RESULTS There was a significant reduction in the peak left ventricular outflow tract (LVOT) gradients immediately following PIMSRA and at 1-year follow-up (resting gradients: from 83.50 (61.25) to 23.00 (41.75) mm Hg, p<0.001 and 13.50 (21.75) mm Hg, p<0.001, respectively; stress-induced gradients: from 118.25 (96.02) to 47.00 (74.50) mm Hg (1 year), p<0.001). There was an improvement in exercise time on stress echocardiography (p<0.001) and distance by 6 min walk test (p=0.034). Immediately after PIMSRA, there was a significant reduction in radial and circumferential strain in the ablated segments (p<0.001), with no change of longitudinal strain. At 1-year follow-up, the radial and circumferential strain recovered in the ablated segments. Meanwhile, left ventricular regional and global longitudinal strain had improved significantly (p<0.05). CONCLUSIONS PIMSRA is an effective treatment for symptomatic HOCM that resulted in a sustained improvement in exercise capacity, a persistent decrease in LVOT gradient, and a measurable increase in myocardial contractile function.

Abstract
Aging is associated with an increasing burden of morbidity, especially for cardiovascular diseases (CVDs). General cardiovascular risk factors, ischemic heart diseases, heart failure, arrhythmias, and cardiomyopathies present a significant prevalence in older people, and are characterized by peculiar clinical manifestations that have distinct features compared with the same conditions in a younger population. Remarkably, the aging heart phenotype in both healthy individuals and patients with CVD reflects modifications at the cellular level. An improvement in the knowledge of the physiological and pathological molecular mechanisms underlying cardiac aging could improve clinical management of older patients and offer new therapeutic targets.

Abstract
BACKGROUND Hypertrophic cardiomyopathy (HCM)-related mortality has been decreasing within the United States; however, persistent disparities in demographic subsets may exist. In this study, we assessed nationwide trends in mortality related to HCM among people ≥15 years of age in the United States from 1999 to 2019. METHODS Trends in mortality related to HCM were assessed through a cross-sectional analysis of the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiological Research database. Age-adjusted mortality rates per 1 000 000 people and associated annual percent changes with 95% CIs were determined. Joinpoint regression was used to assess the trends in the overall, demographic (sex, race and ethnicity, age), and regional groups. RESULTS Between 1999 and 2019, 39 200 HCM-related deaths occurred. In the overall population, age-adjusted mortality rate decreased from 11.2 in 1999 to 5.4 in 2019. Higher mortality rates were observed for males, Black patients, and patients ≥75 years of age. Large metropolitan counties experienced pronounced declines in age-adjusted mortality rate over the study period. In addition, California had the highest overall age-adjusted mortality rate. CONCLUSIONS Over the past 2 decades, HCM-related mortality has decreased overall in the United States. However, demographic and geographic disparities in HCM-related mortality have persisted over time and require further investigation.

Abstract
Vertebrates developed pulmonary circulation and septated the heart into venous and arterial compartments, as the adaptation from aquatic to terrestrial life requires more oxygen and energy. The interventricular septum (IVS) accommodates the ventricular portion of the conduction system and contributes to the mechanical function of both ventricles. Conditions or diseases that affect IVS structure and function (e.g., hypertrophy, defects, other) may lead to ventricular pump failure and/or ventricular arrhythmias with grave consequences. IVS structure and function can be evaluated today using current imaging techniques. Effective therapies can be provided in most cases, although definitions of underlying etiologies may not always be easy, particularly in the elderly due to overlap between genetic and acquired causes of IVS hypertrophy, the most common being IVS abnormality. In this review, state-of-the-art information regarding IVS morphology, physiology, physiopathology, and disease is presented.

Abstract
OBJECTIVES Our goal was to assess the short- and long-term outcomes of surgical treatment for hypertrophic obstructive cardiomyopathy in patients ≥65 years of age compared to patients < 65 years of age. METHODS Sixty-four patients aged ≥65 years, surgically treated for symptomatic hypertrophic obstructive cardiomyopathy, were compared to a control group of 125 patients <65 years. RESULTS Patients aged ≥65 years were less frequently male (36% vs 68%, P < 0.001) and had higher EuroSCORE II scores [1.4 (1.1-2.2) vs 0.8 (0.7-1.2), P < 0.001], lower risk of sudden death, higher pulmonary artery pressure [40 (30-50) vs 30 (30-43), P = 0.04) and more mitral annulus calcifications (44% vs 14%, P < 0.001) compared to younger patients.Hospital death was 1%, with no difference between the 2 groups (1.5% vs 0.8%, P = 0.9).Patients aged ≥65 years had more concomitant coronary bypass grafting (12% vs 5%, P = 0.05) and a higher incidence of blood transfusions (50% vs 17%, P < 0.001) and postoperative atrial fibrillation (19% vs 8%, P = 0.02).Follow-up was 98% complete [median 8.3 (5.3-12.8) years]. The 13-year survival in the group aged ≥65 was 54 (SD: 9) % vs 83 (SD: 5) % in the control group (P < 0.001), but it was comparable to that expected in the age-sex matched general national population.At 13 years, the cumulative incidence function of cardiac death in the elderly group was 19 (SD: 7)%, mostly unrelated to hypertrophic cardiomyopathy causes.At the last follow-up, 90% of patients were in New York Heart Association functional class I-II and 68% were in sinus rhythm. CONCLUSIONS Selected elderly symptomatic patients with hypertrophic obstructive cardiomyopathy can benefit from surgery, with low hospital mortality and morbidity, relief of symptoms and late survival comparable to that expected in the age-sex matched general population.

Front Cardiovasc Med 2022; 9:827860. [PMID: 35369329 PMCID: PMC8965461 DOI: 10.3389/fcvm.2022.827860] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Accepted: 01/21/2022] [Indexed: 11/29/2022] Open
Abstract
Background The thoracoscopic trans-mitral approach can not only facilitate exposure of the ventricular septum, mitral valve, and subvalvular apparatus, it also enables the surgeons to perform concomitant mitral valve intervention. This study aimed to determine the safety and efficacy of thoracoscopic trans-mitral septal myectomy in elderly patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods We reviewed the demographic to clinical characteristics and outcomes of patients who underwent thoracoscopic trans-mitral septal myectomy in our center between April 2019 and April 2021. The population was divided into a younger group (<60 years) and an elderly group (≥60 years). Results There were 46 and 20 patients in the younger and elderly groups, respectively. The majority of patients in the elderly group were female (39.1 vs. 80.0%, P < 0.01). Patients in the elderly group were more likely to be in New York Heart Association Class IV (2.2 vs. 80.0%, P < 0.01). The European System for Cardiac Operation Risk Evaluation II predicted mortality rates were significantly higher (3.97 ± 1.81 vs. 1.62 ± 0.86%, P < 0.01) in the elderly group. In the elderly group, a patient converted to median sternotomy due to left ventricular posterior free wall rupture following septal myectomy and mitral bioprosthetic valve replacement. The patient then underwent double-patch sandwich repair for rupture and mitral mechanical valve replacement and was eventually discharged. All patients in the elderly group were discharged, while one in the younger group died. No patient in the elderly group required permanent pacemaker implantation vs. one in the younger group. Patients in the elderly group were more likely to spend more time in the intensive care unit than those in the younger group (5.44 ± 5.80 days vs. 3.07 ± 2.72, P < 0.05). However, there was no significant intergroup difference in in-hospital mortality or complications. Importantly, the left ventricular outflow tract pressure gradient was significantly decreased from 96.15 ± 32.89 mmHg to 8.2 ± 3.42 mmHg with no residual obstruction in the elderly group. The interventricular septal thickness was significantly decreased from 19.73 ± 3.14 mm to 11.30 ± 2.23 mm. Postoperative mitral regurgitation severity was significantly improved in the elderly group. Conclusion This study demonstrated that thoracoscopic trans-mitral septal myectomy is a feasible option for selected elderly patients with satisfactory outcomes similar to those of young patients.

Abstract
BACKGROUND The impact of comorbid disease states on the development of atrial and ventricular arrhythmias in patients with hypertrophic cardiomyopathy (HCM) remains unresolved. OBJECTIVE Evaluate the association of comorbidities linked to arrhythmias in other cardiovascular diseases (e.g., obesity, systemic hypertension, diabetes, obstructive sleep apnea, renal disorders, tobacco, and alcohol use) to atrial fibrillation (AF) and sudden cardiac death (SCD) events in a large cohort of HCM patients. METHODS A total of 2269 patients, 54 ± 15 years of age, 1392 males, were evaluated at the Tufts HCM Institute between 2004 and 2018 and followed for an average of 4 ± 3 years for new-onset clinical AF and SCD events (appropriate defibrillation for ventricular tachyarrhythmias, resuscitated cardiac arrest, or SCD). RESULTS One or more comorbidity was present in 75% of HCM patients, including 50% with ≥2 comorbidities, most commonly obesity (body mass index [BMI] ≥ 30 kg/m2 ) in 43%. New-onset atrial fibrillation developed in 11% of our cohort (2.6%/year). On univariate analysis, obesity was associated with a 1.7-fold increased risk for AF (p = .03) with 12% of obese patients developing AF (3.3%/year) as compared to 7% of patients with BMI < 25 kg/m2 (1.6%/year; p = .006). On multivariate analysis, age and LA transverse dimension emerged as the only variables predictive of AF. Comorbidities, including obesity, were not independently associated with AF development (p > .10 for each). SCD events occurred in 3.3% of patients (0.8%/year) and neither obesity nor other comorbidities were associated with increased risk for SCD (p > .10 for each). CONCLUSIONS In adult HCM patients comorbidities do not appear to impact AF or SCD risk. Therefore, for most patients with HCM, adverse disease related events of AF and SCD appear to be primarily driven by underlying left ventricular and atrial myopathy as opposed to comorbidities.

Abstract
Hypertrophic cardiomyopathy (HCM) is a hereditary disease with an autosomal dominant pattern of inheritance, that is caused by a mutation in one of several sarcomere genes that encodes components of the contractile system of the heart. Hypertrophic cardiomyopathy has been described as a disease that is more heavily diagnosed in the second decade of life, that may present with abnormal syncopal episodes or sudden cardiac death. However, with a better understanding of the genetic changes that occur in HCM and with improved imaging techniques, there has now been an increased recognition of a late-onset disease that can occur in the elderly population. We report a case of a 73-year-old woman who was found to have HCM after various clinical events took place.

Abstract
An octogenarian presented to our hospital in shock after being “found down” at home. She was dehydrated, hypernatremic, and suffering from a urinary tract infection. Findings of a murmur and those on electrocardiography led to the performance of echocardiography, with all findings consistent with a diagnosis of hypertrophic obstructive cardiomyopathy. The patient was volume resuscitated and administered antibiotics; after stabilization, she was started on a low-dose beta-blocker. Hypertrophic cardiomyopathy is a common genetic disorder that is usually diagnosed in the second to fifth decades of life, rarely being diagnosed at an advanced age. It is also an uncommon cause or contributor to shock. We briefly review the diagnosis and management of hypertrophic cardiomyopathy in older adults, particularly in the setting of shock.

Abstract
Background We report characteristics and outcomes of elderly patients with hypertrophic cardiomyopathy (HCM) with basal septal hypertrophy and dynamic left ventricular outflow tract obstruction. Methods and Results We studied 1110 consecutive elderly patients with HCM (excluding moderate or greater aortic stenosis or subaortic membrane, age 80±5 years [range, 75–92 years], 66% women), evaluated at our center between June 2002 and December 2018. Clinical and echocardiographic data, including maximal left ventricular outflow tract gradient, were recorded. The primary outcome was death and appropriate internal defibrillator discharge. Hypertension was observed in 72%, with a Society of Thoracic Surgeons (STS) score (8.6±6); while 80% had no HCM‐related sudden cardiac death risk factors. Left ventricular mass index, basal septal thickness, and maximal left ventricular outflow tract gradient were 127±43 g/m2, 1.7±0.4 cm, and 49±31 mm Hg, respectively. A total of 597 (54%) had a left ventricular outflow tract gradient >30 mm Hg, of which 195 (33%) underwent septal reduction therapy (SRT; 79% myectomy and 21% alcohol ablation). At 5.1±4 years, 556 (50%) had composite events (273 [53%] in nonobstructive, 220 [55%] in obstructive without SRT, and 63 [32%] in obstructive subgroup with SRT). One‐ and 5‐year survival, respectively were 93% and 63% in nonobstructive, 90% and 63% in obstructive subgroup without SRT, and 94% and 84% in the obstructive subgroup with SRT. Following SRT, there were 5 (2.5%) in‐hospital deaths (versus an expected Society of Thoracic Surgeons mortality of 9.2%). Conclusions Elderly patients with HCM have a high prevalence of traditional cardiovascular rather than HCM risk factors. Longer‐term outcomes of the obstructive SRT subgroup were similar to a normal age‐sex matched US population.
