We report the case of an 86-year-old man found at home with acute chest pain and dyspnea. He presented some episodes of left chest pain combined with dyspnea. The physical examination revealed crackling sounds on the bases of the lungs without other anomalies. Electrocardiograms revealed a transient and complete right bundle branch block with inverted T waves in leads V1, V2, and V3. He was diagnosed with a proximal bilateral acute pulmonary embolism without acute cor pulmonale. We describe a case of a transient bundle branch block, without tachycardia or acute cor pulmonale, revealing a pulmonary embolism...

Trans-diaphragmatic intercostal hernia is a rare entity. Patient with multiple medical comorbidities, including obstructive sleep apnoea, presents with shortness of breath, leg oedema and a bulging swelling through the right chest wall. CT shows partial herniation of the right lung and liver through intercostal space and an echocardiogram reveals right heart failure. He was treated initially with continuous positive airway pressure with poor response and subsequently treated with adaptive servo ventilation with much better symptomatic relief and treatment tolerance...

Brain natriuretic peptide (BNP), also known as a B-type natriuretic peptide, is one of the important biomarkers with a proven role in the diagnosis of congestive heart failure (CHF). Researchers from the different clinical field have researched into the performance features of BNP testing in the acute care set-up to assist and improve in diagnosing CHF and in predicting future morbidity and mortality rates. The potency of BNP has also been researched into in cases like myocardial ischemia and infarction, cor pulmonale, and acute pulmonary embolism (PE)...

Baicalin has a protective effect on hypoxia-induced pulmonary hypertension in rats, but the mechanism of this effect remains unclear. Thus, investigating the potential mechanism of this effect was the aim of the present study. Model rats that display hypoxic pulmonary hypertension and cor pulmonale under control conditions were successfully generated. We measured a series of indicators to observe the levels of pulmonary arterial hypertension, pulmonary arteriole remodeling, and right ventricular remodeling...

Michael R Pinsky
The primary role of the right ventricle (RV) is to deliver all the blood it receives per beat into the pulmonary circulation without causing right atrial pressure to rise. To the extent that it also does not impede left ventricular (LV) filling, cardiac output responsiveness to increased metabolic demand is optimized. Since cardiac output is a function of metabolic demand of the body, during stress and exercise states the flow to the RV can vary widely. Also, instantaneous venous return varies widely for a constant cardiac output as ventilatory efforts alter the dynamic pressure gradient for venous return...

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is a global health issue with cigarette smoking being an important risk factor. COPD affects pulmonary blood vessels, right ventricle, as well as left ventricle leading to the development of pulmonary hypertension (PH), cor-pulmonale (COR-P), right and left ventricular dysfunction. Echocardiography provides a rapid, noninvasive, portable, and accurate method to evaluate cardiac functions. Early diagnoses and intervention for cardiac comorbidities would reduce mortalities...

OBJECTIVE: Right heart failure is associated with increased mortality and morbidity. The optimal treatment for patients with RV failure is not established. The aim of this study is to conduct a systematic review of the literature to assess the relative benefits and harms of digoxin therapy in patients with RV failure. METHODS: We performed a literature search in MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) on Nov. 4, 2014. We did not use publication type, period or language restrictions to the search strategy...

Pulmonary vascular dysfunction is associated with ARDS and leads to increased right-ventricular afterload and eventually right-ventricular failure, also called acute cor pulmonale. Interest in acute cor pulmonale and its negative impact on outcome in patients with ARDS has grown in recent years. Right-ventricular function in these patients should be closely monitored, and this is helped by the widespread use of echocardiography in intensive care units. Because mechanical ventilation may worsen right-ventricular failure, the interaction between the lungs and the right ventricle appears to be a key factor in the ventilation strategy...

Unrelieved upper airway obstruction from highly prevalent adenotonsillar hypertrophy (ATH) has the potential of producing structural remodelling of the pulmonary vascular bed with resultant pulmonary hypertension (PH) and cor pulmonale. This cross-sectional study aimed to determine the local prevalence of PH and examine its clinical and radiological pointers among children with ATH. The airway obstruction was evaluated clinically by grading the nocturnal and daytime symptoms of ATH. A Brodsky scale and adenoid-nasopharynx ratio (AN ratio) were used to categorize tonsil and adenoid size, respectively...

Pulmonary vein thrombosis (PVT) is rather an uncommon condition which presents nonspecifically and is usually associated with lung malignancy and major pulmonary surgery. Rarely could no cause be found. It causes increased pulmonary venous pressure leading to pulmonary arterial vasoconstriction and subsequent pulmonary arterial hypertension and subsequently can cause cor pulmonale if not addressed in timely fashion. Other associated complications like peripheral embolization and stroke have also been reported...

BACKGROUND: Acute chest syndrome (ACS) is the most common cause of death among sickle cell disease (SCD) adult patients. Pulmonary vascular dysfunction (PVD) and acute cor pulmonale (ACP) are common during acute respiratory distress syndrome (ARDS) and their prevalence may be even more important during ARDS related to ACS (ACS-ARDS). The objective of this study was to evaluate the prevalence and prognosis of PVD and ACP during ACS-ARDS. PATIENTS AND METHODS: This was a retrospective analysis over a 10-year period of patients with moderate-to-severe ARDS...

Pulmonary alveolar microlithiasis (PAM) is a rare chronic lung disease characterized by deposition of intra alveolar calcium and phosphate in bilateral lung parenchyma with predominance in lower and mid zones. Etiology and pathogenesis is not fully understood. However, mutation in SLC34A2 gene that encodes a sodium phosphate co-transporter in alveolar type-II cells resulting in formation and accumulation of microliths rich in calcium phosphate due to impaired clearance is considered the cause of disease. Patients with PAM are asymptomatic till development of hypoxemia and cor pulmonale...

OBJECTIVE: To establish evidence-based guidelines for the use of bedside cardiac ultrasound, echocardiography, in the ICU and equivalent care sites. METHODS: Grading of Recommendations, Assessment, Development and Evaluation system was used to rank the "levels" of quality of evidence into high (A), moderate (B), or low (C) and to determine the "strength" of recommendations as either strong (strength class 1) or conditional/weak (strength class 2), thus generating six "grades" of recommendations (1A-1B-1C-2A-2B-2C)...
