BackgroundThe literature indicates that Web-based health information seeking is mostly used for seeking information on well-established diseases. However, only a few studies report health information seeking in the absence of a doctor’s visit and in the context of acute symptoms. ObjectiveThis survey aimed to estimate the prevalence of Web-based health information seeking for acute symptoms and the impact of such information on symptom management and health service utilization. MethodsThis was a cross-sectional study of a convenience sample of 287 Lebanese adults (with a response rate of 18.5% [54/291]) conducted between December 2016 and June 2017. The survey was answered by participants online or through phone-based interviews. ResultsA total of 64.3% of the participants (178/277) reported checking the internet for health information when they had an acute symptom. The rate of those who sought to use Web-based health information first when experiencing acute symptom(s) in the past 12 months was 19.2% (25/130). In addition, 50% (9/18) visited the doctor because of the obtained information, and the rest self-medicated or sought a pharmacist’s advice; the majority (18/24, 75%) improved within 3-4 days. ConclusionsHigher education level and trust in Web-based medical information were two major predictors of Web-based health information seeking for acute symptoms. Seeking Web-based health information first for acute symptoms is common and may lead to self-management by avoiding a visit to the physician. Physicians should encourage their patients to discuss Web-based health information and guide them toward trusted online websites.

- Abstract
Background: Acute coronary syndrome (ACS) post-transcatheter mitral valve repair (TMVR) carries high mortality. We aim to study the incidence and predictors of ACS in patients who underwent TMVR., Research Design and Methods: We queried the U.S. National Readmission Database to identify all cases of TMVR from 2016 to 2019. We further evaluated the incidence of ACS and used multivariable logistic regression to determine independent predictors of ACS in this population., Results: Among 3,742 patients who underwent TMVR, 264 (7.05%) developed ACS. Among ACS patients, 204 (77%) had non-ST-segment elevation ACS and 66 (25%) had ST-segment elevation ACS. Independent predictors of ACS were acute limb ischemia, cardiogenic shock, history of coronary artery disease (CAD), smoking, cardiac arrest, respiratory failure requiring mechanical ventilation, and acute kidney injury. In-hospital mortality among ACS was three times higher in ACS patients than without ACS (16.76% vs. 5.45%, p-value < 0.01)., Conclusions: ACS is not an uncommon complication after TMVR. The occurrence of ACS after TMVR is associated with high in-hospital mortality, longer length of stay, and higher hospital charges. The strongest predictors of ACS in these patients are the development of acute limb ischemia, cardiogenic shock, and a history of CAD.

- Abstract
Since its Food and Drug Administration approval in January 2007, the Angiosculpt scoring balloon catheter has been widely utilized in severely calcified stenotic vascular lesions. We sought to characterize the complication rates, failure modes, and outcomes associated with the Angiosculpt catheter. Using queried events from October 2013 to December 2020 from the Food and Drug Administration Manufacturer and User Facility Device Experience database, we analyzed the Angiosculpt scoring balloon catheter complication rates and mode of failure. A total of 248 complications were reported. Most reported complications occurred in the superficial femoral artery (SFA) (19.4%, n = 48), followed by the left anterior descending artery (8.1%, n = 20). Severe vessel calcifications were reported in (26.6%, n = 66) of the complications. Most complications occurred with damage to the device, such as tip break (44.8%, n = 111) and balloon rupture (26.6%, n = 66). Some complications were due to difficulties in the withdrawal of the catheter (23.8%, n = 59). Balloon rupture is observed at a significantly higher rate amongst calcified vessels (60.6% vs 14.8%), P = < 0.001, and in cases involving the SFA (39.4% vs 11.3%), P = < 0.001. All-cause complications in calcified vessels are associated with the SFA (39.4% vs 12.5%), P = < 0.001, and left anterior descending artery (16.7% vs 5.1%), P = < 0.001. The Angiosculpt scoring balloon catheter has a relatively low complication rate. Most complications were associated with a device tip break, balloon rupture, and difficulties in withdrawal in severely calcified vessels., (Copyright © 2022 Elsevier Inc. All rights reserved.)

- Abstract
Background Pulmonary embolism (PE) is the third leading cause of cardiovascular death after myocardial infarction and stroke. The ideal therapeutic approach for these patients remains undetermined. We report our single-center outcome data for using a catheter-based pulmonary artery thrombectomy using the FlowTriever (Inari Medical, Irvine, CA) device as management for patients with submassive PE. Methods We retrospectively collected data from a single center of patients who underwent thrombectomy using INARI FlowTriever device. The data on baseline characteristics, procedural and clinical outcomes was collected and analysed Results A total of 38 patients with PE treated endovascularly with the FlowTriever device were identified: 33 with submassive PE and five with massive PE. The mean age was 65.9 years (95% CI 61.9 - 69.8), and most patients were male (73.7%). All patients had right heart strain as the main indication for thrombectomy. Four patients (10.53%) required pressor support before the procedure. In 31 patients, pre- and post-thrombectomy average mean pulmonary artery pressure (mPAP) was improved significantly by 22% (p < 0.01). Two patients had significant adverse events at 48 hours (5.26%). One patient experienced procedure-related access site hematoma and life-threatening bleeding, while another developed intraprocedural-related massive hemoptysis and cardiopulmonary arrest. Overall post-procedural length of stay was 7.7 ± 5.6 days; 52.63% of patients (n = 20) required intensive care. Three patients (7.89%) required pressor support before the procedure, and 78.9% of patients (n = 30 of 38) survived hospital discharge. Thirty patients who survived were discharged with oral anticoagulation. There were no device-related complications. Conclusion Randomized trials of interventional devices for submassive PE are warranted to either support or alert the medical community of the safety and efficacy of their use for patients with submassive and massive PE. In time, pulmonary embolism response team (PERT) may generate outcome data that better inform treatment decisions., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Elmoghrabi et al.)

- Abstract
Background: Limited data is available on the comparison of outcomes of transradial (TR) and transfemoral (TF) access for percutaneous coronary intervention (PCI) in patients with end-stage stage renal disease (ESRD)., Methods: Online databases were queried to compare cardiovascular outcomes among TR. and TF in ESRD patients. The outcomes assessed included differences in mortality, cerebrovascular accidents (CVA), periprocedural myocardial infarction (MI), bleeding, transfusion, and periprocedural cardiogenic shock (CS). Unadjusted odds ratios (OR) were calculated using a random-effect effect model., Results: A total of 6 studies including 7,607 patients (TR-PCI = 1,288; TF-PCI = 6,319) were included. The overall mean age was 67.7 years, while the mean age for TR-PCI and TF-PCI was 69.7 years and 67.9 years, respectively. TR-PCI was associated with lower incidence of mortality (OR 0.46 95 % CI 0.30-0.70, p < 0.05, I2 0.00 %), bleeding (OR 0.45 95 % CI 0.29, 0.68, p < 0.05, I2 3.48 %), and transfusion requirement (OR 0.52 95 % CI 0.40, 0.67, p < 0.05, I2 0.00 %) (Fig. 1). There were no differences among TR-PCI and TF-PCI for periprocedural MI, periprocedural CS, and CVA outcomes., Conclusion: TR access was associated with lower mortality, bleeding, and transfusion requirement as compared to TF access in patients with ESRD undergoing PCI., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 Published by Elsevier B.V.)

- Abstract
Background: Transcatheter aortic valve implantation (TAVI) has emerged as a safe and effective alternative to surgical replacement for tricuspid aortic valve (TAV) stenosis. However, utilization of TAVI for aortic stenosis in bicuspid aortic valve (BAV) compared to TAV remains controversial., Methods: We queried online databases with various keywords to identify relevant articles. We compared major cardiovascular events and procedural outcomes using a random effect model to calculate odds ratios (OR)., Results: We included a total of 22 studies comprising 189,693 patients (BAV 12,669 vs. TAV 177,024). In the pooled analysis, there were no difference in TAVI for BAV vs. TAV for all-cause mortality, cardiovascular mortality, myocardial infarction (MI), vascular complications, acute kidney injury (AKI), coronary occlusion, annulus rupture, and reintervention/reoperation between the groups. The incidence of stroke (OR 1.24; 95% CI 1.1-1.39), paravalvular leak (PVLR) (OR 1.42; 95% CI 1.26-1.61), and the need for pacemaker (OR 1.15; 95% CI 1.06-1.26) was less in the TAV group compared to the BAV group, while incidence of life-threatening bleeding was higher in the TAV group. Subgroup analysis mirrored pooled outcomes except for all-cause mortality., Conclusion: The use of TAVI for the treatment of aortic stenosis in selective BAV appears to be safe and effective.

- Abstract
Background: The Turnpike catheters (Teleflex, Wayne, PA, USA) is a microcatheter that was approved by the Food and Drug Administration in November 2014 to be used to access discrete regions of the coronary and peripheral vasculature., Methods: The Manufacturer and User Facility Device Experience (MAUDE) database was queried for reports of the Turnpike catheters from March 2015 through August 2021., Results: A total of 216 reports were found during the study period. After excluding duplicate reports (n = 21), our final cohort included 195 reports. The most common failure mode was catheter tip break or detachment (83%, n = 165) which was significantly associated with over-torquing (p-value = 0.025). The most common clinical consequence was the entrapment of the catheter (33%, n = 65), followed by vessel injury (7.8% n = 15) and vessel occlusion (3.6%, n = 7). Most patients had no consequences (47.0%, n = 93) or recovered (11%, n = 22). A total of 4 deaths were reported. 35.8% of reports (n = 69) specified the presence of severe calcification in the target vessel. Over torquing by interventionists was reported in 33.2% of events (n = 64)., Conclusion: Despite clinical trials demonstrating the safety of the Turnpike catheters, complications can still occur. These data serve to inform operators about potentional risks and complications associated with the use of the device. Physicians should avoid over-torqueing which seems to be the most common mechanism for device complications., Competing Interests: None of the authors have any conflict of interest., (© 2022 The Authors.)

- Abstract
The use of prasugrel and ticagrelor as part of dual antiplatelet therapy is increasing in patients after percutaneous coronary intervention (PCI). Accordingly, we aimed to evaluate their prescription patterns in the National Cardiovascular Data Registry (NCDR) Practice Innovation and Clinical Excellence (PINNACLE) registry. We analyzed patients enrolled in NCDR PINNACLE registry from January 2013 to March 2015 who underwent PCI with drug-eluting stent and were prescribed dual antiplatelet therapy. All patients received aspirin. The primary study outcome was a 3-level variable denoting the second antiplatelet agent prescribed: (1) clopidogrel, (2) prasugrel, or (3) ticagrelor. Baseline characteristics were compared among the 3 groups. Odds ratios and 95% credible intervals were calculated from a nested hierarchical Bayesian logistic regression models to identify independent predictors of prescription of antiplatelet medications, incorporating practice and provider as random effects. Our study cohort consisted of 26,710 patients during our study period January 2013 to March 2015. Seventy nine percent of patients were prescribed clopidogrel, 12% prasugrel, and 11% ticagrelor. Patients aged ≥75 years, women, history of tobacco use, Peripheral Arterial Disease (PAD), hypertension, diabetes, previous vascular complication, heart failure, and stroke/transient ischemic attack were more likely to be on clopidogrel than prasugrel or ticagrelor. The relative percentages of ticagrelor and prasugrel were higher in patients with history of myocardial infarction, compared with those without myocardial infarction. In summary, our study highlights the prescription patterns associated with prescription of antiplatelet agents after PCI. We found that both ticagrelor and prasugrel were mostly prescribed per the current practice guidelines, thus reflecting appropriate guideline adherence by practices in NCDR PINNACLE registry., (Copyright © 2019 Elsevier Inc.

- Abstract
Background: Older adults (≥70-year-old) are under-represented in the published data pertaining to unprotected left main coronary artery disease (ULMCAD)., Hypothesis: Percutaneous coronary intervention (PCI) might be comparable to coronary artery bypass grafting (CABG) for revascularization of ULMCAD., Methods: We compared PCI versus CABG in older adults with ULMCAD with an aggregate data meta-analyses (4880 patients) of clinical outcomes [all-cause mortality, myocardial infarction (MI), repeat revascularization, stroke and major adverse cardiac and cerebrovascular events(MACCE)] at 30 days, 12-24 months & ≥36 months in patients with mean age ≥70 years and ULMCAD. A meta-regression analysis evaluated the effect of age on mortality after PCI. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using random-effects model., Results: All-cause mortality between PCI and CABG was comparable at 30-days (OR0.77, 95% CI 0.42- 1.41) and 12-24-months (OR 1.22, 95% CI 0.78-1.93). PCI was associated with a markedly lower rate of stroke at 30-day follow-up in octogenarians (OR 0.14, 95% CI 0.02-0.76) but an overall higher rate of repeat revascularization. At ≥36-months, MACCE (OR 1.26,95% CI 0.99-1.60) and all-cause mortality (OR 1.39, 95% CI 1.00-1.93) showed a trend favoring CABG but did not reach statistical significance. On meta-regression, PCI was associated with a higher mortality with advancing age (coefficient=0.1033, p=0.042)., Conclusions: PCI was associated with a markedly lower rate of early stroke in octogenarians as compared to CABG. All-cause mortality was comparable between the two arms with a trend favoring CABG at ≥36-months.PCI was however associated with increasing mortality with advancing age as compared to CABG., (© 2019 The Authors.

- Abstract
Objectives: Beta blockers (β-blockers) remain a standard therapy in the early treatment of acute coronary syndromes. However, β-blocker therapy in patients with cocaine-associated chest pain (CACP) continues to be an area of debate due to the potential risk of unopposed α-adrenergic stimulation and coronary vasospasm. Therefore, we performed a systematic review and meta-analysis of available studies to compare outcomes of β-blocker versus no β-blocker use among patients with CACP., Methods: We searched the MEDLINE and EMBASE databases through September 2016 using the keywords 'beta blocker', 'cocaine' and commonly used β-blockers ('atenolol', 'bisoprolol', 'carvedilol', 'esmolol', 'metoprolol' and 'propranolol') to identify studies evaluating β-blocker use among patients with CACP. We specifically focused on studies comparing outcomes between β-blocker versus no β-blocker usage in patients with CACP. Studies without a comparison between β-blocker and no β-blocker use were excluded. Outcomes of interest included non-fatal myocardial infarction (MI) and all-cause mortality. Quantitative data synthesis was performed using a random-effects model and heterogeneity was assessed using Q and I
2 statistics., Results: A total of five studies evaluating 1794 subjects were included. Overall, there was no significant difference on MI in patients with CACP on β-blocker versus no β-blocker (OR 1.36, 95% CI 0.68 to 2.75; p=0.39). Similarly, there was no significant difference in all-cause mortality in patients on β-blocker versus no β-blocker (OR 0.68, 95% CI 0.26 to 1.79; p=0.43)., Conclusions: In patients presenting with acute chest pain and underlying cocaine, β-blocker use does not appear to be associated with an increased risk of MI or all-cause mortality., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

- Abstract
A 50-year-old man presented with acute onset dyspnea following cocaine use. He had severe aortic stenosis (AS), mild mitral regurgitation (MR) due to mitral valve prolapse, and no coronary artery disease on recent coronary angiography. He was in acute heart failure with signs of impending cardiogenic shock. Urgent bedside echocardiography revealed hyperdynamic left ventricular systolic function with acute severe MR from a ruptured chordae tendineae. The acute cocaine-induced spike of his already elevated left ventricular systolic pressure from severe AS likely precipitated chordal rupture of his vulnerable mitral valve. This patient underwent emergent mitral and aortic valve replacements. Although cocaine use has been associated with a myriad of cardiovascular complications, acute MR due to chordal rupture has not, to our knowledge, been previously reported in this setting. Prompt diagnosis with echocardiography and surgical intervention are of paramount importance in the management of acute MR., Competing Interests: Conflict of Interest Disclosure: The authors have completed and submitted the Methodist DeBakey Cardiovascular Journal Conflict of Interest Statement and none were reported.

- Abstract
Patients with unprotected left main coronary artery (ULMCA) disease are increasingly being treated with percutaneous coronary intervention (PCI) using drug-eluting stents (DES), but long-term outcomes comparing PCI with coronary artery bypass grafting (CABG) remain limited. We performed aggregate data meta-analyses of clinical outcomes (all-cause death, nonfatal myocardial infarction, stroke, repeat revascularization, cardiac death, and major adverse cardiac and cerebrovascular events) in studies comparing 5-year outcomes of PCI with DES versus CABG in patients with ULMCA disease. A comprehensive literature search (January 1, 2003 to December 10, 2016) identified 9 studies (6,637 patients). Effect size for individual clinical outcomes was estimated using odds ratio (OR) with 95% confidence intervals (CI) using a random effects model. At 5 years, PCI with DES was associated with equivalent cardiac (OR 0.95, 95% CI 0.62 to 1.46) and all-cause mortality (OR 0.98, 95% CI 0.72 to 1.33), lower rates of stroke (OR 0.50, 95% CI 0.30 to 0.84), and higher rates of repeat revascularization (OR 2.52, 95% CI 1.63 to 3.91); compared with CABG, major adverse cardiac and cerebrovascular events showed a trend favoring CABG but did not reach statistical significance (OR 1.19, 95% CI 0.93 to 1.54). In conclusion, for ULMCA disease, PCI can be considered as a comparably effective and yet less invasive alternative to CABG given the comparable long-term mortality and lower incidences of stroke., (Copyright © 2017 Elsevier Inc.

Acute aortic dissection is rare among young patients in the absence of connective tissue disorders. One of the risk factors associated with aortic dissection among young patients is amphetamine use. We report a case of a 37-year-old female with a past medical history of hypertension presenting with syncope and altered mental status who was found to have an acute DeBakey Type I aortic dissection after ingestion of 3,4-methylenedioxymethamphetamine (MDMA), commonly known as ecstasy. This is the second case in the literature describing aortic dissection in relation to MDMA use. In both cases, the patients were young and had no history of connective tissue disorders or underlying valvular abnormalities. In this case, echocardiography was used to establish the diagnosis early. A transthoracic echocardiogram revealed a possible dissection flap prolapsing in through a normal aortic valve. Subsequently, a transesophageal echocardiogram revealed wide-open aortic regurgitation with several proximal dissection flaps from a normal caliber ascending aorta prolapsing into a normal tricuspid aortic valve. A high index of suspicion is necessary to diagnose and treat aortic dissection in young patients with a history of MDMA use., Learning Objective: Recognize MDMA as a risk factor for acute aortic dissection, especially among younger patients with whom clinicians may not often associate aortic dissection., (Copyright © 2016 Hellenic Cardiological Society.

- Abstract
The development of multiple diagnostic intracoronary imaging modalities has increased our understanding of coronary atherosclerotic disease. These imaging modalities, intravascular ultrasound (IVUS), optical coherence tomography (OCT), and near-infrared spectroscopy (NIRS), have provided a method to study plaques and introduced the concept of plaque vulnerability. They are being increasingly used for percutaneous coronary intervention (PCI) optimization and are invaluable tools in research studying the pathophysiology of acute coronary syndrome (ACS), in-stent thrombosis and in-stent restenosis. IVUS has the ability to visualize the intracoronary lumen and the vessel wall and can be used to detect early atherosclerotic disease even in the setting of positive arterial remodeling. Studies supporting the use of IVUS to optimize stent deployment and apposition have shown a significant reduction in cardiovascular events. OCT provides even higher resolution imaging and near microscopic detail of plaques, restenoses, and thromboses; thus, it can identify the etiology of ACS. Ongoing trials are evaluating the role of OCT in PCI and using OCT to study stent endothelialization and neointimal proliferation. NIRS is a modality capable of localizing and quantifying lipid core burden. It is usually combined with IVUS and is used to characterize plaque composition. The benefits of NIRS in the setting of ACS have been limited to case reports and series. The utilization of all these intracoronary imaging modalities will continue to expand as their indications for clinical use and research grow. Studies to support their use for PCI optimization resulting in improved outcomes with potential to prevent downstream events are ongoing.

- Abstract
Introduction . Inflammatory pseudotumor is an uncommon entity, and its cardiac origin is exceedingly rare. Case History . A previously healthy 27-year-old man was found to have a systolic murmur during preemployment screening evaluation. A transthoracic echocardiogram revealed a 4 × 2.5 cm mass originating from the right ventricle (RV) outflow tract extending into the aortic root. A computed tomography guided biopsy confirmed an IgG4-related inflammatory pseudotumor. Patient was started on oral prednisone with subsequent reduction in mass size. Conclusion . Cardiac inflammatory pseudotumors are markedly rare tumors that should be considered in the differential of intracardiac tumors which otherwise includes cardiac fibromas, myxomas, and sarcomas., Competing Interests: The authors declare no conflict of interests.

- Abstract
Postprandial lipemia has been associated with acute endothelial dysfunction. Endothelial dysfunction, in turn, is associated with increased arterial stiffness. However, the relationship between postprandial lipemia and acute changes in arterial stiffness has not been extensively investigated. Therefore, we conducted a pilot study on the effects of postprandial lipemia on arterial stiffness in 19 healthy young adults before and after consumption of a high-fat mixed meal. Arterial stiffness was assessed locally with echo-tracking carotid arterial strain (CAS) and globally with carotid-femoral pulse wave velocity (PWV). As assessed by these two benchmark parameters, arterial stiffness did not differ significantly postprandially. However, the arterial distension period (ADP) was significantly lower 2 hours after mixed meal ingestion. In addition, slopes of carotid artery area (CAA) curves were significantly steeper postprandially. Therefore, we concluded that ADP may be a more sensitive marker of arterial stiffness in healthy young adults when compared to PWV and CAS., (© The Author(s) 2015.)

- Abstract
Antinuclear antibody (ANA) negative lupus is an important subset of the systemic lupus erythematosus (SLE) disease spectrum. Since the introduction of human cell line for ANA assay, the occurrence of true ANA-negative SLE has been a rare clinical phenomenon. The nature of cardiac involvement in ANA-negative SLE is not well understood, although any cardiac involvement, including valvular dysfunction, should be considered as a presenting manifestation of SLE irrespective of serology status. Early recognition and intervention appears to be associated with decreased morbidity. The following report describes our first case of ANA-negative SLE with an initial presentation of severe cardiac valvular dysfunction and heart failure. It also characterizes the spectrum of disease severity in ANA-negative SLE and demonstrates how aggressive SLE therapy can improve cardiac disease.

- Abstract
Background: Secundum atrial septal defect (ASD) is a common congenital heart defect in adults. If untreated, ASD leads to right ventricular (RV) failure, atrial arrhythmias, and pulmonary hypertension. The aim of this study is to analyze published data on outcomes and complications of percutaneous ASD closure in adults., Methods: PubMed searches performed for published literature on percutaneous ASD closure using the terms ASD, ASD closure or repair, and percutaneous or transcatheter closure., Results: A total of 23 studies, 1958 patients, were analyzed. Baseline characteristics showed mean age of 49.1 ± 1.7 years, Qp:Qs of 2.2 ± 0.05, defect size 19.4 ± 1 and device size 24.0 ± 0.7. The percentage of patients in NYHA class I, II and III was 42.4 ± 6.3, 40.0 ± 6.5, and 9.3 ± 3.0, respectively. Mean follow-up was 12.6 ± 4.9 months with a closure rate of 96.9% ± 1.4. Echocardiographic parameters of improvement included decrease in RV volume from 157.2 to 100.2 mL (p = 0.02), RV end-diastolic dimensions from 40.8 to 32.4 mm (p < 0.0001) and pulmonary artery systolic pressures from 42.2±2.2 to 34.4±2.4 (p < 0.0001). The percentage of patients in NYHA class II and III decreased from 55±7.5 to 15.9±4.4 (p = 0.0013). At the end of follow-up, complications included 1% mortality rate, 0.8% device embolization, 5.8% new onset arrhythmias and 1.2% need for surgical closure., Conclusion: Our study confirms that percutaneous ASD closure in adults with moderate pulmonary hypertension and RV dilation is safe and effective with reverse remodeling and better functional capacity. Prospective studies are needed to evaluate efficacy of percutaneous ASD closure in adults with large defects, higher shunt ratios, and severe pulmonary hypertension.

- Abstract
Left coronary cusp perforation is an extremely rare consequence of blunt chest trauma. A 22-year-old male presented after a motor vehicle accident with dyspnea. Transthoracic echocardiogram (TTE) and transesophageal echocardiogram (TEE) showed moderate to severe aortic regurgitation with prolapsing right coronary cusp. In the operating room he was found to have a left coronary cusp tear near the annulus and an enlarged right cusp. The patient recovered well after successful aortic valve replacement with a mechanical valve. Traumatic aortic regurgitation with left cusp perforation is serious and surgical intervention may be lifesaving if performed timely.
