Massive pulmonary embolism is life threatening and can present as cardiogenic shock and cardiac arrest. We report a case of a 47-year-old male who arrested during his postoperative hospitalization and was found to have a massive pulmonary embolism with bilateral involvement of the pulmonary arteries. Given his profound shock and right ventricular failure, an Impella RP was used to stabilize his acute right ventricular failure while percutaneous embolectomy and thrombolysis was used to treat the pulmonary embolism...

INTRODUCTION: Obesity is associated with significantly better outcome after acute myocardial infarction (AMI), a phenomenon known as 'obesity paradox'. Tricuspid annular plane systolic excursion (TAPSE) is an echocardiographic measurement of right ventricular (RV) function and has prognostic implications at the time of AMI. METHODS: We examined the difference in RV function among patients admitted with AMI according to obesity status. In a single center cohort analysis of 105 patients admitted between 2010 and 2011 with the diagnosis of AMI...

Kathrine Knai, Nils Kristian Skjaervold
BACKGROUND: The aim of this study was to construct a non-invasive model for acute right ventricular afterload increase by hypoxic pulmonary vasoconstriction. Intact animal models are vital to improving our understanding of the pathophysiology of acute right ventricular failure. Acute right ventricular failure is caused by increased afterload of the right ventricle by chronic or acute pulmonary hypertension combined with regionally or globally reduced right ventricular contractile capacity...

A 13-year obese female with suspected viral myocarditis presented with acute decompensated heart failure. Due to her body habitus, she was a poor candidate for immediate heart transplantation. A peripherally inserted left ventricular assist device (LVAD) was implanted via the right axillary artery. Following device insertion the patient experienced rapid improvement in symptoms. The LVAD provided effective left ventricular unloading for 50 days, promoting myocardial recovery and maintaining excellent patient performance status...

REVIEW
Jeffrey P Jacobs
Three basic principles provide the rationale for the Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database (CHSD) public reporting initiative: (1) Variation in congenital and pediatric cardiac surgical outcomes exist. (2) Patients and their families have the right to know the outcomes of the treatments that they will receive. (3). It is our professional responsibility to share this information with them in a format they can understand. The STS CHSD public reporting initiative facilitates the voluntary transparent public reporting of congenital and pediatric cardiac surgical outcomes using the STS CHSD Mortality Risk Model...

A Medtronic MICRA transcatheter pacing system (TPS) was implanted in an 86-year old patient with sick sinus syndrome and left bundle branch block after transfemoral aortic valve implantation. During implantation she developed a persistent complete heart block due to manipulation with the large bore delivery catheter. Two weeks later, acute pacemaker dysfunction occurred due to massive increase of pacing threshold and impedance without obvious pacemaker dislocation or myocardial perforation. Recurrent capture failure was seen with pacing output set at 5 V / 1...

BACKGROUND: Pompe disease is an autosomal recessive disorder caused by deficiency of the lysosomal α-1,4-glucosidase leading to accumulation of glycogen in target tissues with progressive organ failure. While the early infantile-onset form is characterized by early severe hypertrophic cardiomyopathy with cardiac and respiratory failure, clinically relevant cardiomyopathy seems to be uncommon in patients with late-onset Pompe disease, and the prevalence and nature of myocardial abnormalities are still to be clarified...

In pediatric heart transplantation, the size of the donor organ is an important criterion for organ allocation. Oversized donor hearts are often accepted with good results, but some complications in relation to a high donor-recipient ratio have been described. Our patient was transplanted for progressive heart failure in dilated cardiomyopathy. The donor-to-recipient weight ratio was 3 (donor weight 65 kg, recipient weight 22 kg). The intra-operative echocardiography before chest closure showed excellent cardiac function, no tricuspid valve regurgitation, and a normal central venous pressure...

OBJECTIVE: To explore the predictive value of heart-type fatty acid binding protein (H-FABP) in the stratification and prognosis of patients with acute pulmonary embolism (APE). METHODS: According to risk stratification, 69 patients with APE admitted into the emergency department within 24 hours after onset were divided into the following 3 groups: high-risk group, moderate-risk group and low-risk group. H-FABP- and cardiac troponin I (cTNI)-positive rates of all groups were analyzed and compared, and the correlation between major adverse events (death, endotracheal intubation and cardiopulmonary resuscitation) and the cardiac markers (heart rate, arterial partial pressure of oxygen, right ventricular dimension, pulmonary arterial pressure, etc...

BACKGROUND: Surgical experience with chronic constrictive pericarditis (CCP) is rarely documented in Africa; the aim of this study is therefore to review our African experience with CCP from 1977 to 2012 in terms of clinical and surgical outcomes and risk factors of early death after pericardiectomy. METHODS: This retrospective study is related to 120 patients with CCP; there were 72 men and 48 women with an average age at 28.8±10.4 years standard deviation (SD) (8-51 years)...

BACKGROUND: Hemorrhagic shock and pneumonectomy causes an acute increase in pulmonary vascular resistance (PVR). The increase in PVR and right ventricular (RV) afterload leads to acute RV failure, thus reducing left ventricular (LV) preload and output. iNO lowers PVR by relaxing pulmonary arterial smooth muscle without remarkable systemic vascular effects. We hypothesized that with hemorrhagic shock and pneumonectomy, iNO can be used to decrease PVR and mitigate right heart failure. METHODS: A hemorrhagic shock and pneumonectomy model was developed using sheep...

Pulmonary veno-occlusive disease (PVOD) is rare condition which can lead to severe pulmonary hypertension, right ventricular dysfunction, and cardiopulmonary failure. The diagnosis of PVOD can be challenging due to its nonspecific symptoms and its similarity to idiopathic pulmonary arterial hypertension and interstitial lung disease in terms of diagnostic findings. This case describes a 57 year old female patient who presented with a 5-month history of progressive dyspnea on exertion and nonproductive cough...

Acute right ventricular failure (RVF) is an increasingly clinical problem and a life-threatening condition. Right ventricular assist devices (RVADs) represent a reasonable treatment option for patients with refractory RVF. We here present a novel percutaneously implantable device for RV support.The PERKAT device is based on a nitinol stent cage which is covered with valve- carrying foils. A flexible outlet trunk with a pigtail tip is connected to the distal part. The device is driven by an IABP drive unit which inflates/deflates a standard IABP balloon placed within in the stent cage...

OBJECTIVES: The use of short-term mechanical circulatory support (MCS) has increased in the treatment of refractory cardiogenic shock (RCS). Percutaneous short-term MCS technology has emerged rapidly; however, limitations in flow and durability remain. We therefore investigated a minimally invasive surgical approach using an external ventricular assist device (VAD) and extracorporeal membrane oxygenation (ECMO) in patients with RCS. METHODS: Twenty-five patients underwent minimally invasive external VAD insertion with a magnetically levitated centrifugal pump for various causes of cardiogenic shock between April 2010 and May 2016...

BACKGROUND: Pulmonary hypertension (PH) is associated with poor outcomes, yet specific treatments only exist for a small subset of patients. The most common form of PH is that associated with left heart disease (Group 2), for which there is no approved therapy. Nitrite has shown efficacy in preclinical animal models of Group 1 and 2 PH, as well as in patients with left heart failure with preserved ejection fraction (HFpEF). We evaluated the safety and efficacy of a potentially novel inhaled formulation of nitrite in PH-HFpEF patients as compared with Group 1 and 3 PH...

Right Heart Thrombus (RiHT) management is really controversial, and appropriate guidelines are not present for the management. In patients referring with RiHT and Pulmonary Embolism (PE), there are three ways of managing these patients. Out of the three, one is thrombectomy, which is with high risk taking in mind the comorbidities these patients have. The other is using thrombolytic which, in many cases is contraindicated or with high risk. The other less effective way is full anticoagulation. It is really controversial to choose between these ways of management and no clear approach is present...

BACKGROUND: Exercise is beneficial in pulmonary arterial hypertension (PAH), although studies to date indicate little effect on the elevated pulmonary pressures or maladaptive RV hypertrophy associated with the disease. For chronic LV failure, high intensity interval training (HIIT) promotes greater endothelial stimulation and superior benefit than customary continuous exercise training (CExT); however, HIIT has not been tested for PAH. Therefore, here we investigated acute and chronic responses to HIIT vs...

AIMS: Data on the prognostic role of left and right bundle branch blocks (LBBB and RBBB), and nonspecific intraventricular conduction delay (IVCD; QRS ≥ 110 ms, no BBB) in acute heart failure (AHF) are controversial. Our aim was to investigate electrocardiographic predictors of long-term survival in patients with de novo AHF and acutely decompensated chronic heart failure (ADCHF). METHODS AND RESULTS: We analysed the admission electrocardiogram of 982 patients from a multicenter European cohort of AHF with 3...
