RESUMEN

OBJECTIVES: We compared the long-term outcomes of percutaneous coronary intervention with second-generation drug-eluting stents (PCI-DES) and coronary artery bypass graft surgery (CABG) with the left internal mammary artery in stable angina patients with isolated single-vessel proximal left anterior descending artery (pLAD) disease. BACKGROUND: Long-term outcomes of second-generation PCI-DES and CABG in isolated pLAD lesions have not been extensively studied. METHODS: We included 631 PCI-DES patients and 379 CABG patients. Unadjusted and adjusted hazard ratios (HRs) were derived for major adverse cardiac events (MACEs), their components (cardiac death, nonfatal myocardial infarction [MI] not attributed to a non-target vessel, target-lesion revascularization), and patient-related outcome (PRO, composed of all-cause mortality, any MI, any revascularization). RESULTS: In the unadjusted and adjusted analyses, no significant difference was observed between the two groups at follow-up (mean:4.6 ± 2.5 years) for MACEs (HR: 1.45, 95% CI: 0.92-2.28, p = .11; HR:1.43, 95% CI: 0.91-2.26, p = .13), PRO (HR: 1.18, 95%CI: 0.86-1.61, p = .30; HR: 1.18, 95% CI: 0.86-1.62, p = .31), cardiac death (HR: 0.97, 95% CI: 0.46-2.05, p = .93; HR: 0.79, 95% CI: 0.36-1.72, p = .56) and MI (HR: 1.43, 95% CI: 0.49-4.13, p = .51; HR: 1.57, 95% CI: 0.53-4.64, p = .42). Compared with CABG, PCI-DES had a borderline significantly greater risk of repeat revascularization (HR: 1.99, 95% CI: 1.00-3.94, p = .05; HR: 1.95, 95% CI: 0.98-3.9, p = .06). Angina recurred more often after PCI (p < .001), whereas more arrhythmias developed after CABG (p = .02). PCI-DES resulted in fewer in-hospital complications (p < .001) and shorter hospitalizations (p < .001). CONCLUSIONS: The long-term clinical outcomes of second-generation PCI-DES and CABG in patients with stable angina and isolated pLAD disease were comparable.

RESUMEN

Sickle cell disease (SCD) is an inherited monogenic hemoglobinopathy characterized by formation of sickle erythrocytes under conditions of deoxygenation. Sickle erythrocytes can lead to thrombus formation and vaso-occlusive episodes that may result in hemolytic anemia, pain crisis and multiple organ damage. Moreover, SCD is characterized by endothelial damage, increased inflammatory response, platelet activation and aggravation, and activation of both the intrinsic and the extrinsic coagulation pathways. Cerebrovascular events constitute an important clinical complication of SCD. Children with SCD have a 300-fold higher risk of acute stroke and by the age of 45 about 25% of patients have suffered an overt stoke. Management and prevention of stroke in patients with SCD is not well defined. Moreover, the presence of patent foramen ovale (PFO) increases the risk of the occurrence of an embolic cerebrovascular event. The role of PFO closure and antiplatelet or anticoagulation therapy has not been well investigated. Moreover, during COVID-19 pandemic and taking into account the increased rates of thrombotic events and the difficulties in blood transfusion, management of SCD patients is even more challenging and difficult, since data are scarce regarding stroke occurrence and management in this specific population in the COVID-19 era. This review focuses on pathophysiology of stroke in patients with SCD and possible treatment strategies in the presence of PFO.

RESUMEN

Transcatheter aortic valve replacement (TAVR) is the mainstay for treating high-risk patients with aortic stenosis. As the TAVR procedures worldwide keep increasing, it is inevitable that more issues and complications will arise. Such a complication that merits attention is the conversion of TAVR into open-heart surgery and the necessity this complication creates to have an extracorporeal circulation system in the catheterization laboratory. This review contains an analysis of all major randomized trials and registries on the number and cause of TAVR procedures that ended up in open-heart surgery and presents data to challenge the prerequisite of extracorporeal circulation system in the cath laboratory. © 2015 Wiley Periodicals, Inc.

RESUMEN

OBJECTIVE: The aim of the present study was to assess the level of access site pain in patients undergoing transradial coronary catheterization by using topical application of an anesthetic ointment (lidocaine/prilocaine-AO) compared to standard local anesthesia (LA) by means of injectable lidocaine. METHODS: We prospectively studied 444 patients undergoing elective trans-radial coronary angiography. The quality of analgesia was assessed using a visual analogue scale (VAS) immediately after the puncture and 30 min after the removal of the sheath. The number and duration of attempts before successful sheath insertion, as well as artery spasm, were compared between the two groups. RESULTS: Pain levels measured by VAS were found to be similar between the two groups during sheath insertion (VAS: AO: 4.84 ± 1.0 vs 4.82 ± 1.2, P = NS), as well as 30 min after sheath removal (VAS: AO: 0.07 ± 0.5 vs LA: 0.15 ± 0.6, P = NS). The time to obtain radial access was also not affected by the use of anesthetic ointment (AO: 62.24 ± 25.7 s vs LA: 64.04 ± 18.78 sec, P = NS). The rate of clinical or angiographic radial artery spasm was similar (8-10%) between the groups (P = NS) CONCLUSION: Use of a local anesthetic ointment, versus injectable lidocaine, in trans-radial cardiac catheterization as means of local anesthesia, was found to be equally effective in terms of pain, artery spasm, or artery cannulation speed.

RESUMEN

BACKGROUND AND PURPOSE: Microwave radiometry allows noninvasive in vivo measuring of internal temperature of tissues reflecting inflammation. In the present study, we evaluated the predictive accuracy of this method for the diagnosis of coronary artery disease (CAD). METHODS: Consecutive patients (n=287) scheduled for coronary angiography were included in the study. In carotid arteries of both groups, the following measurements were performed: (1) intima-media thickness (IMTmax) and (2) temperature measurements by microwave radiometry (ΔTmax). C-statistic and net reclassification improvement were used to compare the prediction ability of the markers IMTmax and ΔTmax for the presence of CAD and multivessel CAD. RESULTS: Of 287 patients, 239 had stenoses ≥50% (CAD group), and 48 did not have significant stenoses (NO-CAD group). ΔTmax was an independent predictor for the presence of CAD and multivessel CAD, showing similar predictive accuracy to intima-media thickness, as assessed by c-statistic and net reclassification improvement. CONCLUSIONS: Local inflammatory activation, as detected by microwave radiometry, has similar predictive accuracy to intima-media thickness for the presence and extent of CAD.

RESUMEN

BACKGROUND: We performed a network meta-analysis of randomized controlled trials comparing non-vitamin K antagonist oral anticoagulant (NOAC)-based versus vitamin K antagonists (VKA)-based regimens in patients with atrial fibrillation (AF) and acute coronary syndromes or PCI, aiming to examine the precise impact of recently established antithrombotic strategies on major bleeding as primary end-point and other safety and efficacy as secondary end-points. METHODS: A literature search was conducted for randomized controlled trials. Our search took place in three major databases. The primary endpoint of our study was bleeding. To combine direct and indirect evidence across trials, a frequentist network meta-analysis with a random-effects model was used. RESULTS: Five studies were found eligible for the meta-analysis enrolling a total of 11,542 patients. Five studies (N = 4903 patients) contributed to the network. Compared to the triple antithrombotic therapy (TAT)-based VKA, only the dual antithrombotic therapy (DAT) based NOAC reduced the bleeding (RR 0.57, 95%CI 0.40-0.82). There was no statistically significant difference between DAT-based VKA (RR = 0.66, 95%CI = 0.40-1.09) or TAT-based NOAC (RR = 0.80, 95%CI = 0.43-1.49). DAT-based NOAC ranked best (P-score = 0.91), followed by DAT-based VKA (P-score = 0.67), TAT-based NOAC (P-score = 0.40), and TAT-based VKA (P-score = 0.03). CONCLUSION: The network meta-analysis of four antithrombotic strategies, demonstrated that in patients with AF undergoing PCI the combination of DAT-based NOAC is associated with a significantly lower risk of major bleeding events. This strategy does not seem to be less effective in terms of prevention of ischemic events compared to the other regimens.

RESUMEN

Tricuspid regurgitation (TR) is a common valvular pathology, estimated to affect 1.6 million people in the United States alone. Even though guidelines recommend either medical therapy or surgical treatment for TR, the misconception of TR as a benign disease along with the high mortality rates of surgical intervention led to undertreating this disease and commonly describing it as a "forgotten" valve. Recently, the development of transcatheter interventions for TR show promising potential for use in the clinical setting. There are currently few approved and numerous tested percutaneously delivered devices, which can be categorized, based on their mechanism of action, to either valve repair or valve replacement procedures. Both procedures were tested in clinical trials and show an echocardiographic reduction in TR sustained for at least 1 year after the procedure, as well as symptom relief and functional improvement of the patients. Device selection should be personalized, taking into consideration the anatomy of each valve and the available options at each heart center. Moreover, appropriate patient selection and timing of the procedure are also crucial for the success of the procedure. In this review, we analyze the clinical trials available for all devices currently approved or tested, aiming to provide a comprehensive summary of the most recent evidence in the field of transcatheter TR interventions.

RESUMEN

Chronic heart failure (CHF) is characterized by decreased nitric oxide (NO) bioavailability. In addition, the beneficial NO turns to be deleterious when it reacts with superoxide anion, leading to peroxynitrite formation. Numerous experimental and clinical studies have reported increased production of reactive oxygen species (superoxide, hydrogen peroxide, hydroxyl radical) both in animals and patients with CHF. Moreover, there are indicative data suggesting mechanisms associated with endothelial dysfunction in states of CHF, mainly attributed to decreased NO bioavailability and enhanced inactivation of the latter. Thus, such molecules appear to be potential targets in patients with CHF. These patients are strong candidates to receive a variety of therapeutic agents, some of which have known antioxidant effects. Classic treatment with statins or angiotensin converting enzyme inhibitors has been found to be beneficial in restoring NO and improving myocardial function and structure. Other agents such as sildenafil and b-blockers along with novel agents such as NO synthase transcription enhancers have been proved to be also beneficial, but their use for such a purpose is still controversial. Approaches using more-effective antioxidants or targeting myocardial oxidant-producing enzymes and oxidative or nitrosative stress might be promising strategies in the future.

RESUMEN

A 67-year-old male presented with non-ST-segment elevation myocardial infarction. Angiography showed severe restenosis within the previously (before 2 years) implanted 2 stents (3 x 24 mm) in the right coronary artery. Severe calcification was evident angiographically and after multiple dilations with noncompliant balloons, the focal underexpansion of the stent remained. A 3-mm x 12-mm intravascular lithotripsy balloon was used and after the third series of 10 pulses, full expansion of the stent was observed. Postdilation of the stenosis with noncompliant and drug-eluting balloons was accompanied by excellent angiographical result with no residual stenosis. The patient was discharged free of symptoms and remains uneventful with no complications. The case demonstrates the feasibility of intravascular lithotripsy in acute coronary syndromes related to stent underexpansion due to severe calcification that is refractory to other conventional techniques.

RESUMEN

This case report describes a 64-year-old female with history of previous intravenous drug abuse on opioid substitution treatment with buprenorphine, who presented to the emergency department with angina and electrocardiographic findings suggestive of acute coronary syndrome. Echocardiography and left ventriculography were indicative of takotsubo cardiomyopathy, probably attributed to abrupt discontinuation of buprenorphine. Opioid withdrawal leads to sympathetic hyperactivity and increased catecholamine release, which in our case triggered takotsubo cardiomyopathy presentation. .

RESUMEN

BACKGROUND: Chronic kidney disease (CKD) is associated with a higher incidence of cardiovascular death especially as the disease progresses and patients are on long-term dialysis treatment. Left ventricular (LV) dysfunction and cardiac deformation measured by speckle tracking echocardiography seem to play an important prognostic role in several different specific populations. OBJECTIVE: Τhe prognostic value of strain analysis measurements, including the novel diastolic parameters such as left atrial (LA) strain, in patients with end-stage renal disease on dialysis (stage 5 CKD). METHODS: 67 patients (mean age 62.3 ± 11.8, 65.7% men) with stage 5 CKD (45 on hemodialysis and 22 on peritoneal dialysis) were enrolled in the study protocol. The mean duration of dialysis was 102.48 ± 84.98 months. Mean follow-up lasted seven years. RESULTS: Most of the study population had normal or mildly impaired systolic function with a mean LV ejection fraction of 49.17% (± 10.41) while 70% of patients had impaired LV global longitudinal strain, mean 14.35% (± 4.49). Regarding LA strain parameters the mean LA reservoir, LA conduit, and LA contractile reserve were 24.11% (± 12.61), 10.56% (± 5.88), and 13.60% (± 9.15) respectively. Thus 50% of the population had impaired LA strain. Logistic regression analysis showed that of the various echocardiographic parameters LV ejection fraction, LV global longitudinal strain, and the conduit phase of LA strain were significantly associated with total prognosis (p = 0.009, p = 0.007, p = 0.05). The conduit element of LA strain was the strongest predictor among them, when adjusted for age (OR = 0.77 p = 0.04). CONCLUSIONS: Left ventricular diastolic dysfunction is an important prognostic factor in patients with advanced CKD on long-term dialysis, without known CAD. The novel echocardiographic parameters such as LA strain could add valuable information to the overall cardiac evaluation of this specific population.

RESUMEN

Electrocardiogram (ECG) still remains a very useful diagnostic method in modern cardiology. Its broad availability, noninvasiveness and good sensitivity explain why it plays a capital role in the very beginning of the process of diagnosis for every patient, with or without cardiac-related complaints. For the practitioner, good training in ECG interpretation is mandatory. Sometimes, the ECG trace reveals particular aspects that may cause confusion and complicate decision-making. In this article, we present several less common situations underlying the general context and ECG features. The syndromes studied have a high pathological significance and may range from acute emergencies that call for a rapid therapeutical response to chronic syndromes that require prolonged observation, monitoring and risk stratification.

RESUMEN

BACKGROUND: Plaque rupture is the most common pathology associated with non-ST-elevation myocardial infarction (NSTEMI) and ST-elevation myocardial infarction (STEMI). However, limited data are available regarding ruptured plaque morphology and its relationship with the clinical syndrome. This study aimed (1) to provide a morphologic description of ruptured culprit lesions by optical coherence tomography (OCT) and (2) to investigate whether ruptured plaque morphology differs between NSTEMI and STEMI. METHODS: We included 84 consecutive patients with NSTEMI and STEMI undergoing OCT study of the culprit lesion. We identified patients with plaque rupture in the OCT study and used them as the study population. Qualitative and quantitative analysis of ruptured plaque morphology was then performed, followed by a comparison of the morphological characteristics in patients with STEMI and NSTEMI. RESULTS: Fifty-five patients (70.5%) with rupture, 25 with NSTEMI, and 30 with STEMI were used for analysis. Plaque was ruptured at the minimal lumen in 34.5% of the cases, whereas 69% of the ruptures occurred at the plaque shoulder. Ruptured cap thickness was ≤90 µm in 96% of ruptured plaques. Patients with NSTEMI had greater minimal luminal area (P < .001), less lipid content (P = .01), and lower rupture length (P < .001) and length of missing fibrous cap (P < .05) compared with patients with STEMI. CONCLUSIONS: Rupture of the plaque in myocardial infarction usually occurs in sites different than the minimal lumen and at the shoulder of areas with fibrous cap measuring ≤90 µm. Patients with STEMI have greater plaque disruption and smaller minimal lumen area than patients with NSTEMI.

RESUMEN

Vortex formation time (VFT) is a dimensionless index used to quantify duration of vortex ring formation during diastole. We sought to investigate the effect of pharmaceutical stress on VFT in patients evaluated for ischemia. For this purpose, a standard dobutamine stress echo (DSE) protocol was performed in 50 consecutive patients, and VFT was calculated at rest and at peak. VFT was calculated from echocardiography measurements using a previously developed mathematical equation. VFTi was calculated as the percentage of change of VFTpeak, compared with VFTrest. Mean VFTrest was 2.46 (0.73) and mean VFTpeak 1.67 (0.57) with mean VFTi - 30.0% (19.8). In 14 (28%) patients, an ischemic response (DSE+) was documented. VFTi was significantly lower in DSE+ patients a finding which remained significant in the multivariate analysis after adjusting for age, sex, hypertension, diabetes, history of coronary artery disease, and relative increase of heart rate during stress.

RESUMEN

The purpose of this work was to evaluate the relation between serum glucose levels at hospital admission and left ventricular systolic function in nondiabetic patients with an acute coronary syndrome (ACS). Of the 1000 ACS patients who were consecutively enrolled during 2007-2008, 583 (63 +/- 13 years, 20% females) nondiabetic patients were studied in this work. Of these, 254 presented left ventricular systolic dysfunction (ejection fraction <40%). Biochemical measurements and detailed medical information were recorded in all participants. Patients having glucose levels at hospital admission in the highest tertile (>155 mg/dl) had lower left ventricular ejection fraction (40% vs 45%, P = 0.003), were older (66 +/- 11 vs 61 +/- 13, P = 0.004) and less physically active (49% vs 63%, P = 0.02), had higher troponin (14.7 +/- 39.7 vs 5.6 +/- 13.5, P = 0.03), higher brain natriuretic peptide (510.39 +/- 932.33 vs 213.4 +/- 301.14, P = 0.008), higher C-RP (42.26 +/- 55.26 vs 26.46 +/- 38.18, P = 0.04), lower creatinine clearance levels (68 +/- 33 vs.81 +/- 31, P = 0.009), higher white blood cell count (13 416 +/- 16 420 vs 9310 +/- 3020, P = 0.001), and lower body mass index (26.8 +/- 4 vs 27.2 +/- 4.4, P = 0.07), compared to those in the lowest tertile (<114 mg/dl). The multiadjusted logistic regression analysis revealed that a 10 mg/dl difference in glucose levels was independently associated with 8% (95% confidence interval 2%-14%) higher likelihood of left ventricular systolic dysfunction. Low glucose concentrations at hospital admission in nondiabetic post-ACS patients is a predictor for the appearance of left ventricular dysfunction, and could be a target marker for risk stratification.

RESUMEN

Background: Right but not left ventricular hemodynamic parameters have been found to be independently associated with adverse renal outcomes in patients with acute decompensated heart failure (HF).Aim: To investigate the hemodynamic profile of patients without acute decompensated heart failure and left ventricular ejection fraction >50% referred for elective left and right heart catheterization and to correlate left and right filling pressures, stroke volume and arterial blood pressure to renal function parameters. Subsequently, we tested the hypothesis that right ventricle and left ventricle hemodynamic parameters can predict all-cause mortality in our non-HF subjects.Methods: Between October 2009 and November 2010, 151 consecutive patients referred for elective left and right heart catheterization were studied and consequently followed up for a mean period of 8 years in order to identify all-cause mortality. Patient's initial cohort was subdivided in two groups according to right atrial pressure. The RAPRLOW group (Right Atrium Pressure ≤ 9 mmHg) and the RAPRHIGH group (Right Atrium Pressure > 9mmHg)Results: No correlation between blood pressure, pulmonary capillary wedges pressure, cardiac index, stroke volume and stroke volume index (SVI), and parameters of kidney function was observed. However, a weak, although, significant correlation between right atrial pressure (RAP) and modification of diet in renal disease (MDRD) (r = -0.202; p = .014) could be detected. RAPRLOW patients had a statistically significant lower MDRD value of 16.6 mL/min/1.73 m2 than RAPRHIGH patients. Increased RAP (HR = 2.03; 95% [CI]: 1.05 to 3.9; p = .025) and age (HR = 1.08, 95% [CI] 1.04-1.12, p < .001) independently predicted all-cause mortality during follow up.Conclusions: Our study demonstrates that right ventricular preload affects renal function in patients with preserved systolic function and that neither aortic systolic pressure nor left ventricle pressure indices were related to estimated glomerular filtration rate. Furthermore, we demonstrate for the first time that an increased RAP is able to predict a worse prognosis in patients with preserved ejection fraction independently of well-established risk factors, such as blood pressure and SVI.

RESUMEN

In patients undergoing percutaneous closure of secundum atrial septal defect, the device selection is decided based on three-dimensional transesophageal echocardiography (3D TEE) measurements and two-dimensional balloon stretched diameter measurements; more importantly balloon sizing. The purpose of the study was to assess whether in patients with "halo-sign", defined as increased tissue thickness at the edge of the ASD rims, there is an agreement between 3D TEE and 2D balloon stretched diameter aiming to avoidance of balloon sizing. Forty consecutive patients who underwent closure of a single, without complex anatomy ASD were included. 3D and 2D TEE datasets were acquired and analyzed offline. Planimetry was used to calculate circumference derived diameter of ASD from 3D datasets. Patients were classified according to the presence of the "halo sign" and the agreement between circumference derived diameter and balloon stretched diameter was examined. Forty consecutive patients who underwent closure of a single, without complex anatomy ASD were included. 3D and 2D TEE datasets were acquired and analyzed offline. Planimetry was used to calculate circumference derived diameter of ASD from 3D datasets. Patients were classified according to the presence of the "halo sign" and the agreement between circumference derived diameter and balloon stretched diameter was examined. Higher correlation and lower median absolute difference between 3D TEE measurements and 2D stretched balloon diameter was found in patients with "halo sign". In patients with the "halo sign" mean diameter difference was non-significant. On the contrary statistically significant difference was found in patients without the "halo sign". Significant difference was also found when comparing mean difference in the two patient groups. ASD sizing by 3D echocardiography, is accurate in patients with halo sign and it correlates well with the balloon sizing method. This study justifies further investigation concerning the reliability of 3D imaging for the selection of the ASD device size with a view to avoid balloon sizing, decrease procedural time and thus simplify the procedure.

RESUMEN

Cardiac masses are space occupying lesions within the cardiac cavities or adjacent to the pericardium. They include frequently diagnosed clinical entities such as clots and vegetations, common benign tumors such as myxomas and papillary fibroelastomas and uncommon benign or malignant primary or metastatic tumors. Given their diversity, there are no guidelines or consensus statements regarding the best diagnostic or therapeutic approach. In the past, diagnosis used to be made by the histological specimens after surgery or during the post-mortem examination. Nevertheless, evolution and increased availability of cardiovascular imaging modalities has enabled better characterization of the masses and the surrounding tissue. Transthoracic echocardiography using contrast agents can evaluate the location, the morphology and the perfusion of the mass as well as its hemodynamic effect. Transesophageal echocardiography has increased spatial and temporal resolution; hence it is superior in depicting small highly mobile masses. Cardiac magnetic resonance and cardiac computed tomography are complementary providing tissue characterization. The scope of this review is to present the role of cardiovascular imaging in the differential diagnosis of cardiac masses and to propose a step-wise diagnostic algorithm, taking into account the epidemiology and clinical presentation of the cardiac masses, as well as the availability and the incremental value of each imaging modality.

RESUMEN

OBJECTIVES: We sought to assess the comparative value of inflammatory markers on the occurrence of left ventricular systolic dysfunction (LVSD) after an acute coronary syndrome (ACS). METHODS: During 2006-2008, 760 patients with an ACS were enrolled. C-reactive protein (CRP) and white blood cell (WBC) count were measured during the first 12 hours of hospital admission. RESULTS: CRP levels and WBC count were significantly higher in those who developed LVSD compared to those who did not. The analysis revealed that a 10 mg/dL increase of CRP levels and a 1000/microL increase in WBC are associated with a 6% and a 7% increase in the likelihood of developing LVSD, respectively. Furthermore, WBC count at entry and CRP have almost the same predictive value for development of LVSD after an ACS (R(2) = 0.109 versus R(2) = 0.093). CONCLUSIONS: Serum CRP levels and WBC count at entry are almost equally powerful independent predictors of LVSD, after an ACS.
