ABSTRACT
Background: Chronic obstructive pulmonary disease (COPD) is a common respiratory condition involving the airways and characterized by airflow limitation. Pulmonary hypertension (PH) is a well-known predictor of increased morbidity and mortality in COPD. The present study was done to assess the cardiac changes in patients diagnosed with COPD in this department using two-dimensional echocardiography.Methods: This observational study was conducted on fifty patients admitted with signs and symptoms suggestive of COPD in the Department of Pulmonary Medicine, Dr. DY Patil Medical College, Navi Mumbai from January 2018 to December 2018. Pulmonary function tests (PFT) were done in all and patients were graded according to the severity of COPD with guidelines given by Global initiative for Obstructive Lung Disease (GOLD). Comprehensive two-dimensional echocardiography was performed.Results: The most common age group was 60 to 69 years. There were 68% males and 32% females. Mean body mass index of the patients included in the study was 27.8±8.13 kg/m2. COPD according to the GOLD classification was mild, moderate, severe and very severe in 12%, 36%, 30% and 22% of the patients. PH was diagnosed in 56% of the patients, Cor pulmonale in 54%, right ventricular dilatation in 48%, right atrial dilatation in 38%, inter-ventricular septal wall motion abnormality in 18% and right ventricular failure in 14% of the patients.Conclusions: Echocardiography examination is a reliable method in COPD patient to assess PH and helps in early detection of cardiac complications in COPD cases giving time for early interventions.
ABSTRACT
El fallo agudo del ventrículo derecho (VD) es un síndrome clínico complejo que puede ser causado por muchas causas y es el responsable del 3% al 9% de los ingresos en las unidades de cuidados intensivos con una mortalidad intrahospitalaria del 5 al 17%. Puede presentarse de forma solapada o grave con compromiso hemodinámico severo y shock. El objetivo primario debe ser la identificación y el tratamiento de la causa subyacente de insuficiencia del VD, como la embolia pulmonar aguda, síndrome de dificultad respiratoria aguda, descompensación aguda de la hipertensión pulmonar crónica, infarto VD, o arritmias. Se ha reconocido la importancia de la función del VD en la insuficiencia cardíaca, el infarto de miocardio, la cardiopatía congénita y la hipertensión pulmonar. Actualmente, los avances en ecocardiografía y resonancia magnética nuclear han creado nuevas oportunidades para el estudio de la anatomía y fisiología del VD. La presente revisión ofrece una perspectiva clínica sobre la estructura y función del VD. En esta primera parte, revisaremos la anatomía, fisiología, evaluación y fisiopatología del VD. En la segunda parte, revisaremos la importancia clínica y el manejo y tratamiento del fallo del VD.
Acute failure of the right ventricle Part 1 Anatomy, physiology, functional evaluation and pathophysiology of the right ventricle Acute right ventricular (RV) failure is a complex clinical syndrome that can be caused by many causes and accounts for 3% to 9% of admissions in intensive care units with in-hospital mortality of 5% to 17%. It can present in an overlapping or severe way with severe hemodynamic compromise and shock. The primary objective should be the identification and treatment of the underlying cause of RV insufficiency, such as acute pulmonary embolism, acute respiratory distress syndrome, acute decompensation of chronic pulmonary hypertension, RV infarction, or arrhythmias. The importance of RV function in heart failure, myocardial infarction, congenital heart disease and pulmonary hypertension has been recognized. Currently, advances in echocardiography and nuclear magnetic resonance have created new opportunities for the study of RV anatomy and physiology. The present review offers a clinical perspective on the structure and function of the RV. In this first part, we will review the anatomy, physiology, evaluation and pathophysiology of the RV. In the second part, we will review the clinical importance and the management and treatment of RV failure.

ABSTRACT
Right ventricular failure (RVF) is the main cause of death in patients with cardiopulmonary disease, such as pulmonary arterial hypertension (PAH), pulmonary embolism, acute respiratory distress syndrome, and right ventricular infarction. The exact cellular and molecular mechanisms underlying RVF remains unclear. Inflammation may play an important role during the development of RVF, as it does in left heart failure. Cardiac inflammation has been shown in RVF patients and animal models, which played a role in the impairment of the right ventricular contraction and in the maladaptive remodeling. Inflammation plays a dual role in the development of cardiopulmonary disease and its anti-inflammatory therapies may have double benefits for RVF patients. This review summarizes the evidence of inflammation in RVF and research progresses of inflammation in the development of RVF to provide a reference for further exploring the mechanism of inflammation in RVF.
ABSTRACT
Abstract The last decade has seen considerable growth in the use of left ventricular assist devices (LVAD), in end-phase heart failure treatment. The indications, contraindications and implantation techniques are well-defined. However, information about mechanical support for right ventricular failure is lacking. The aim of this communication is to present alternative techniques for implantation of short- and longterm right ventricular assist devices. Implanting the device in the right atrium has certain advantages when compared with the right ventricle. It is an easier surgical technique that preserves the tricuspid valve and it can potentially reduce the risk of pump thrombosis.

Right ventricular failure(RVF)is a severe clinical syndrome that affects human health seriously.The establishment and application of experimental animal models are critical to research the pathogenesis, pathophysiology, prevention and treatment of RVF.Recently, numerous researchers have studied the modeling methods and testing indexes of RVF of animal models, which has improved the success rate and quality of the models.However, even if so many models, there is still no widely accepted experimental animal model of RVF because of the different and complex modeling methods, material selection and experimental conditions.This article reviews the methods and mechanism of multiple experimental animal models of RVF and compares them, so as to provide reference for choosing and applying experimental animal models of RVF in the study.
ABSTRACT
OBJECTIVES: The purpose of the present study is to emphasize the efficacy of the myocardial performance index and tricuspid annular plane systolic excursion (TAPSE) in the determination of impaired cardiac functions and recovery period following the treatment in children with adenoid and/or tonsillar hypertrophy. METHODS: Fifty-three healthy children after routine laboratory, imaging and clinical examinations, with adenoid and/or tonsillar hypertrophy were evaluated before and 3 months after adenotonsillectomy for cardiac functions using M mode and Doppler echocardiography. RESULTS: The mean age of cases was 6.4±3.0 years, 34 (65%) were male, and 19 (35%) were female. Pulmonary hypertension was observed to be mild in 3 patients and moderate in 1 patient preoperatively. When the preoperative and postoperative echocardiographic measurements of the patients were compared, the tricuspid valve E wave velocity, the E/A ratio (E, early diastolic flow rate; A, late diastolic flow rate), and the TAPSE values were determined to be significantly higher postoperatively (P<0.05). The tricuspid valve deceleration time, the isovolumetric relaxation time and the systolic pulmonary artery pressure were found to be significantly lower compared to the preoperative values (P<0.05). CONCLUSION: Adenoidectomy and/or tonsillectomy may prevent cardiac dysfunctions that can develop in the later periods due to adenoid and/or tonsil hypertrophy in children, before the appearance of the clinical findings of cardiac failure.

Extracorporeal membrane oxygenation (ECMO) is a useful but less commonly used technique in right ventricular failure post cardiac surgery in our region. We report a case of successful use of ECMO for right ventricular failure post cardiac surgery. Our patient is a 27-year-old male presented with constrictive pericarditis post completion of treatment for disseminated Tuberculosis. He underwent pericardiectomy that was complicated with acute right ventricular failure. He was placed on extracorporeal membrane oxygenation after few hours post op that lasted for five days. The patient survived to hospital discharge and remained well on follow-up. From our experience, this aggressive management approach is beneficial in right ventricular failure and can be safely utilised in all cardiothoracic centres.
ABSTRACT
Acute cholecystitis after cardiac surgery is rare but carries a high mortality. Intraaortic balloon pump (IABP) is effective and useful device for mechanical assistance for heart. We reported a case of 34-year-old patient who had experienced pulmonary hypertension and right ventricular failure during cholecystectomy for acute cholecystitis after cardiac surgery. Thus, the patient was mechanically supported with IABP and hemodynamics and cardiac function were improved.

Primary pulmonary hypertension is characterized by progressive increase in pulmonary vascular resistance leading to right ventricular (RV) failure and death.The desirable goal of primary pulmonary hypertension is preserving coronary perfusion of RV while decreasing pulmonary arterial pressure with selective pulmonary vasodilators.We report a case in which anesthetic management was successfully performed in a 67 years old man, who had experienced ventricular tachycardia at the previous anesthesia induction, with severe pulmonary hypertension and right ventricular dysfunction.

Not a few patients in children and adolescents are suffering from right ventricular (RV) dysfunction resulting from various conditions such as chronic lung disease, left ventricular dysfunction, pulmonary hypertension, or congenital heart defect. The RV is different from the left ventricle in terms of ventricular morphology, myocardial contractile pattern and special vulnerability to the pressure overload. Right ventricular failure (RVF) can be evaluated in terms of decreased RV contractility, RV volume overload, and/or RV pressure overload. The management for RVF starts from clear understanding of the pathophysiology of RVF. In addition to correction of the underlying disease, management of RVF per se is very important. Meticulous control of volume status, inotropic agents, vasopressors, and pulmonary selective vasodilators are the main tools in the management of RVF. The relative importance of each tool depends on the individual clinical status. Medical assist device and surgery can be considered selectively in case of refractory RVF to optimal medical treatment.

BACKGROUND: Pulmonary hypertension in COPD patients is the result of a direct effect of tobacco smoke on the intrapulmonary vessels with the abnormal production of the mediators that control vasoconstriction, vasodilatation, and vascular cell proliferation, which ultimately lead to aberrant vascular remodeling and physiology. COPD patients are prone to the developmint of an acute and chronic thromboembolism with an elevation of the plasma procoagulant and fibrinolytic markers However, the roles of the coagulation and fibrinolysis system on the right ventricular dysfunction in COPD patients are not well defined. We examined the alteration of the coagulation and fibrinolysis system in COPD patients according to the right ventricular function measured using cardiac multidetector computed tomography (MDCT). METHODS: The right ventricular ejection fraction (RVEF) was measured using cardiac MDCT in 26 patients who were diagnosed with COPD according to the definition of the GOLD guideline. The plasma level of thrombin antithrombin (TAT) and plasminogen activator inhibitor (PAI)-1 were measured using an enzyme linked immunoassay. RESULTS: The plasma TAT was markedly elevated in COPD patients (10.5+/-19.8microgram/L) compared with those of the control (3.4+/-2.5 microgram/L) (p<0.01). However, the plasma PAI-1 in COPD patients (29.6+/-20.7 ng/mL) was similar to that in the controls. The plasma TAT showed a significant inverse relationship with the RVEF measured by the cardiac MDCT in COPD patients (r=-0.645, p<0.01). However, the plasma PAI-1 did not show a relationship with the RVEF (r=0.022, p=0.92). CONCLUSION: These results suggest that the coagulation system in COPD patients is markedly activated, and that the plasma level of TAT might be a marker of a right ventricular dysfunction in COPD patients.

The intraaortic balloon pump (IABP) is the most effective and widely used device for temporary mechanical assistance of left heart. Considering left and right ventricular (RV) interdependence, IABP may also alleviate predominantly RV dysfunction following cardiac surgery. This is the case of a 61-year-old female patient who had experienced RV failure after cardiac surgery. After tricuspid valve replacement, preexisting RV failure was progressively aggravated and systemic blood pressure could not be maintained in spite of aggressive pharmacological support on second postoperative day. Thus, mechanical support with IABP was considered to increase coronary perfusion pressure in this case. IABP dramatically improved hemodynamics and cardiac function. It was removed on fifth postoperative day and she has remained well. In conclusion, IABP could play a role in RV failure following cardiac surgery and timely treatment of the heart failure with mechanical circulatory assistance would prevent further complications.
