Resuscitation 2022; 177:63-68. [PMID: 35671843 DOI: 10.1016/j.resuscitation.2022.06.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Revised: 05/28/2022] [Accepted: 06/01/2022] [Indexed: 12/27/2022]
Abstract
BACKGROUND Pulmonary hypertension (PH) has been associated with poor survival in multiple cardiopulmonary conditions, however its association with outcomes in cardiac arrest remains unknown. We aimed to evaluate the association of PH with survival and neurologic outcomes in adults with in-hospital cardiac arrest (IHCA). METHODS The study population included adults with IHCA undergoing resuscitation at an academic tertiary medical center from 2011-2019. Patients were classified based upon the presence versus absence of PH, defined as a pulmonary artery systolic pressure > 35mmHg on pre-arrest echocardiogram. Survival to discharge and favorable neurological outcome (defined as a Glasgow Outcome Score of 4-5) served as the primary and secondary outcomes of interest respectively. RESULTS Of the 371 patients studied, 203 (54.7%) had PH while 168 (45.3%) did not. Patients with PH had higher Charlson Comorbidity Score with higher rates of multiple baseline comorbidities. They also had worse multi-chamber enlargement, left ventricular diastolic dysfunction, right ventricular systolic dysfunction, and valvular heart disease compared to non-PH patients. Rates of survival to discharge (11.5% vs 10.9%, p=0.881) and favorable neurologic outcome (8.0% vs 6.2%, p=0.550) were similar in PH and non-PH patients respectively. In multivariable analysis, PH was not associated with survival to discharge (OR 1.23, 95%CI 0.57-2.65) or favorable neurologic outcome (OR 1.69, 95%CI 0.64 - 4.45). CONCLUSIONS In this contemporary registry of adults with IHCA, while PH was associated with a higher risk patient profile, it was not associated with survival or neurologic outcomes in this population.

Abstract
Abstract
Current management of valvular heart disease (VHD) seeks to optimize long-term outcome by timely intervention. Recommendations for treatment of patients with symptoms due to severe valvular disease are based on a foundation of solid evidence. However, when to intervene in asymptomatic patients remains controversial and decision requires careful individual weighing of the potential benefits against the risk of intervention and its long-term consequences. The primary rationale for earlier intervention is prevention of irreversible left ventricular (LV) myocardial changes that might result in later clinical symptoms and adverse cardiac events. A number of outcome predictors have been identified that facilitate decision-making. This review summarizes current recommendations and discusses recently published data that challenge them suggesting even earlier intervention. In adults with asymptomatic aortic stenosis (AS), emerging risk markers include very severe valve obstruction, elevated serum natriuretic peptide levels, and imaging evidence of myocardial fibrosis or increased extracellular myocardial volume. Currently, transcatheter aortic valve implantation (TAVI) is not recommended for treatment of asymptomatic severe AS although this may change in the future. In patients with aortic regurgitation (AR), the potential benefit of early intervention in preventing LV dilation and dysfunction must be balanced against the long-term risk of a prosthetic valve, a particular concern because severe AR often occurs in younger patients with a congenital bicuspid valve. In patients with mitral stenosis, the option of transcatheter mitral balloon valvotomy tilts the balance towards earlier intervention to prevent atrial fibrillation, embolic events, and pulmonary hypertension. When chronic severe mitral regurgitation is due to mitral valve prolapse, anatomic features consistent with a high likelihood of a successful and durable valve repair favour early intervention. The optimal timing of intervention in adults with VHD is a constantly changing threshold that depends not only on the severity of valve disease but also on the safety, efficacy, and long-term durability of our treatment options.

Impact of Preoperative Measurement of Right Heart Chambers in the Evaluation of Pulmonary Hypertension Following Aortic Valve Replacement. Chest 2020; 157:1597-1605. [PMID: 31958443 DOI: 10.1016/j.chest.2019.12.017] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2019] [Revised: 11/15/2019] [Accepted: 12/04/2019] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Severe pulmonary hypertension (PH) in patients with aortic stenosis is related to poor prognosis following aortic valve replacement (AVR). Current European PH guidelines recommend adding two different echocardiographic signs to tricuspid regurgitation velocity (TRV) in PH estimation, classifying its probability as low (TRV ≤ 2.8 m/s), intermediate (TRV 2.9-3.4 m/s), and high (TRV > 3.4 m/s). The right ventricle is an important determinant of prognosis in PH. The goal of this study was to analyze the value of right atrial area > 18 cm2 and right ventricular/left ventricular ratio > 1 in the long-term prognosis following AVR, mainly in the intermediate probability group. METHODS This study included 429 consecutive patients (mean age, 73 ± 8 years; 55% male) with a median follow-up of 4.25 years (completed in 98%). Patients were divided into low (n = 247), intermediate (n = 117), and high probability groups (n = 65). The intermediate probability group was divided into two subgroups: subgroup 2a (n = 27; TRV nonmeasurable or ≤ 2.8 m/s and two signs present) and subgroup 2b (n = 90; TRV 2.9-3.4 m/s, and none or only one sign present). RESULTS Overall mortality rates during follow-up of the low, intermediate, and high probability groups were 24%, 32%, and 42%, respectively. High PH probability was an independent predictor of all-cause mortality (hazard ratio [HR], 1.82; 95% CI, 1.11-3.00), but the intermediate probability group did not reach significance following multivariate analysis (HR, 1.40; 95% CI, 0.91-2.16). When the intermediate probability group was divided into subgroups, the subgroup 2a mortality rate (56%) was higher than that of both subgroup 2b (24%; P = .002) and the low probability group (24%; P < .001). Following multivariate analysis, subgroup 2a showed a significantly higher mortality (HR, 2.13; 95% CI, 1.11-4.10) in contrast to subgroup 2b (HR, 1.24; 95% CI, 0.75-2.05), both compared with the low probability group. CONCLUSIONS Incorporating measurement of the right cavities into the PH probability model in the assessment of long-term prognosis following AVR allowed better risk discrimination, especially in the intermediate probability group.

Abstract
BACKGROUND AND AIM OF THE STUDY We compared early and late outcomes of surgical aortic valve replacement (SAVR) in patients with aortic stenosis (AS) and pulmonary hypertension (PHT). METHODS We searched MEDLINE and EMBASE databases until July 2018 for studies comparing patients with AS and none, mild-moderate, or severe PHT undergoing SAVR. Random-effects meta-analysis was performed. RESULTS There were 12 observational studies with 70 676 patients with median follow-up 4.0 years (interquartile range, 2.6-4 years). Compared to patients with no PHT, patients with any PHT undergoing SAVR were older (mean difference [MD], 2.31 years; 95% confidence interval [CI], 1.38-3.23 years; P < .01), with greater comorbidities and reduced ejection fraction (MD, -4.36; 95%CI, -5.94 to -2.78; P < .01). Patients with any PHT had higher unadjusted (5.2% vs 2.4%; risk ratio [RR], 2.27; 95%CI, 2.04-2.53; P < .01) and adjusted (RR, 1.65; 95%CI, 1.28-2.14; P < .01) in-hospital mortality compared with no PHT. Severe (RR, 3.53; 95%CI, 1.46-8.54; P < .01) and mild-moderate PHT (RR, 2.13; 95%CI, 1.28-3.55; P < .01) were associated with higher unadjusted in-hospital mortality compared with no PHT. Any PHT was associated with a higher unadjusted risk of stroke (RR, 1.64; 95%CI, 1.42-1.90; P < .01), acute kidney injury (RR, 2.02; 95%CI, 1.50-2.72; P < .01), prolonged ventilation (RR, 1.62; 95%CI, 1.04-2.52; P = .03), and longer hospital stay (MD, 1.76 days; 95%CI, 0.57-2.95; P < .01). Severe (HR, 2.44; 95%CI, 1.60-3.72; P < .01) but not mild-moderate PHT (HR, 2.25; 95%CI, 0.91-5.59; P = .08) was associated with higher adjusted long-term mortality compared with no PHT. CONCLUSIONS Patients with severe AS and severe PHT had a significant increase in operative mortality and more than double the risk of long-term mortality following SAVR compared with patients with no PHT. Such patients may benefit from a less invasive transcatheter aortic valve intervention.

Abstract
Echocardiography is the key tool for the diagnosis and evaluation of aortic stenosis. Because clinical decision-making is based on the echocardiographic assessment of its severity, it is essential that standards are adopted to maintain accuracy and consistency across echocardiographic laboratories. Detailed recommendations for the echocardiographic assessment of valve stenosis were published by the European Association of Echocardiography and the American Society of Echocardiography in 2009. In the meantime, numerous new studies on aortic stenosis have been published with particular new insights into the difficult subgroup of low gradient aortic stenosis making an update of recommendations necessary. The document focuses in particular on the optimization of left ventricular outflow tract assessment, low flow, low gradient aortic stenosis with preserved ejection fraction, a new classification of aortic stenosis by gradient, flow and ejection fraction, and a grading algorithm for an integrated and stepwise approach of artic stenosis assessment in clinical practice.

Abstract
Baseline pulmonary hypertension (PH) is a predictor of poor outcomes in patients with severe aortic stenosis (AS). Surgical aortic valve replacement is thought to alleviate PH. The aim of this study was to determine the prognostic impact of PH in patients who underwent transcatheter aortic valve replacement (TAVR). An observational cohort study was conducted using prospectively collected data on 277 consecutive patients with severe AS who underwent TAVR at the Mayo Clinic (Rochester, Minnesota) from November 1, 2008, to June 31, 2013. Clinical and echocardiographic data, pulmonary function characteristics, and outcomes stratified by tertiles of pulmonary artery systolic pressure (PASP) were analyzed. From 277 patients who underwent TAVR, 251 patients had PASP assessment at baseline. Those in the highest PASP tertile (PASP ≥49 mm Hg) had more severe chronic lung disease and worse diastolic dysfunction. Being in the highest PASP tertile was an independent predictor of long-term mortality (hazard ratio 2.88, 95% confidence interval 1.15 to 7.23). Patients in the highest PASP tertile had longer lengths of hospital stay, while other short-term outcomes (30-day mortality and readmission, stroke, prolonged ventilation, and reoperation for bleeding) were similar across PASP tertiles. TAVR was associated with a decrease in PASP in the highest PASP tertile at 1 week after the procedure (-8 ± 14 mm Hg) and at 3 months (-7 ± 15 mm Hg) compared with baseline. In conclusion, among patients with severe AS who underwent TAVR, higher baseline PASP was strongly associated with diastolic dysfunction and chronic lung disease. Patients with higher baseline PASP tolerated TAVR relatively well in the early postprocedural phase, with diminished long-term survival. PH should not disqualify patients with severe AS from consideration for TAVR.
