Article Synopsis
  • Pulmonary embolism (PE) is a major cause of hospital deaths and cardiovascular issues, with traditional treatments like anticoagulation and surgery being standard options.
  • Recent advancements include catheter-directed interventions (CDI), such as thrombolysis, which may quickly enhance patient outcomes, despite limited supporting evidence from clinical trials.
  • A joint report highlights the need for rapid response teams, thorough patient evaluation, and collaborative methods to optimize treatment and outcomes for those dealing with PE.

Introduction And Objectives: Chronic thromboembolic disease refers to the presence of chronic thrombotic pulmonary vascular thrombosis without pulmonary hypertension (PH) at rest but with exercise limitation after pulmonary embolism (PE). Our aim was to evaluate the hemodynamic response to exercise in these patients and its correlation with the values reached in cardiopulmonary exercise testing.

Methods: We included symptomatic patients with persistent pulmonary thrombosis after PE.

Background: Catheter directed therapies (CDT) are widely used in the treatment of acute pulmonary embolism (PE). A multicenter registry was organized to evaluate their application in real life and to determine efficacy and safety of these procedures. Local experience of participating centers in percutaneous techniques for PE treatment was assessed.

Introduction And Objectives: Catheter-directed therapy (CDT) for acute pulmonary embolism (PE) is an emerging therapy that combines heterogeneous techniques. The aim of the study was to provide a nationwide contemporary snapshot of clinical practice and CDT-related outcomes.

Methods: This Investigator-initiated multicenter registry aimed to include consecutive patients with intermediate-high risk (IHR) or high-risk (HR), acute PE eligible for CDT.

Introduction And Objectives: The management of persistent moderate-severe tricuspid regurgitation (TR) in patients with chronic thromboembolic pulmonary hypertension after treatment with pulmonary endarterectomy (PEA) or balloon pulmonary angioplasty (BPA) is not well defined. This study aimed to analyze the progression and predictors of significant persistent postintervention TR and its prognostic impact.

Methods: This single-center observational study included 72 patients undergoing PEA and 20 who completed a BPA program with a previous diagnosis of chronic thromboembolic pulmonary hypertension and moderate-to-severe TR.

(1) Background: Pulmonary endarterectomy (PEA) is the "gold standard" treatment for operable patients with chronic thromboembolic pulmonary hypertension (CTEPH). Persistent pulmonary hypertension (PH) after PEA confers a worse prognosis. Balloon pulmonary angioplasty (BPA) could represent a useful therapy in this setting, but evidence about its effectiveness and safety in patients with previous PEA is limited.

Article Synopsis
  • Patients with spontaneous coronary artery dissection (SCAD) who presented as ST-segment-elevation myocardial infarction (STEMI) exhibited more severe coronary lesions and worse blood flow compared to those presenting as non-ST-segment elevation myocardial infarction (NSTEMI).
  • During treatment, STEMI patients were more frequently treated with percutaneous coronary intervention (PCI) and had higher rates of left ventricular systolic dysfunction, but both groups had similar rates of major adverse events during hospital admission.
  • In the long term, despite the initial differences in severity and treatment, both STEMI and NSTEMI SCAD patients had comparable outcomes concerning major adverse cardiac and cerebrovascular events.

Article Synopsis
  • Advanced age and related health issues often prevent older patients with chronic thromboembolic pulmonary hypertension (CTEPH) from undergoing pulmonary endarterectomy, making balloon pulmonary angioplasty (BPA) a promising alternative, albeit with limited existing data on its safety and effectiveness for this age group.
  • A study involving 33 patients aged 70 and above who underwent BPA showed significant improvements in health metrics, including reduced pulmonary arterial pressure and enhanced cardiac function, along with a favorable safety profile.
  • The results indicated that BPA is not only safe but also effective in reducing symptoms and medication needs, with only a small percentage of procedures leading to serious complications.

Background: Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome. Multivessel (MV) SCAD is a challenging clinical presentation that might be associated to a worse prognosis compared with patients with single-vessel (SV) involvement.

Methods: The Spanish multicentre nationwide prospective SCAD registry included 389 consecutive patients.

Objective: Spontaneous coronary artery dissection (SCAD) is an infrequent cause of acute coronary syndrome. Our aim was to assess adverse events at follow-up from a nationwide prospective cohort.

Methods: The Spanish Registry on SCAD (SR-SCAD) included patients from 34 hospitals.

A 16-years-old male with prior diagnosis of situs inversus totalis and pulmonary atresia with interventricular communication underwent percutaneous pulmonary valve implantation 3 months after successful RVOT stenting following a negative balloon sizing test. Once finished the procedure, after consciousness recovery in the intensive care unit, the patient developed oppressive chest pain with very subtle electrocardiographic changes over his basal right bundle branch block. An urgent coronary angiography showed a severe stenosis in the proximal right coronary artery with TIMI 2 distal flow.

Article Synopsis
  • The study aimed to evaluate how effective intravascular ultrasound (IVUS) is when added to coronary angiography (CA) for diagnosing and treating left main coronary artery (LMCA) compression caused by pulmonary hypertension (PH).
  • LMCA compression is a serious issue that can arise from pulmonary artery aneurysms in PH patients, but IVUS is rarely used, even though guidelines suggest it.
  • The results showed that while CA could misidentify compressions, IVUS accurately confirmed compression in patients suspected of having LMCA issues, leading to a low rate of significant clinical problems over an extended follow-up period.

Pulmonary artery aneurysm (PAA) is a common finding in patients with long-term pulmonary arterial hypertension (PAH). The influence of PAH severity in the development of PAA remains unclear. We sought to determine whether PAA development is related to PAH severity and whether treatment optimization based on risk profile estimation is effective to stop pulmonary artery (PA) enlargement.

Detection of pulmonary artery aneurysms (PAA) in pulmonary arterial hypertension (PAH) is increasing. We sought to determine the frequency of PAA in a PAH cohort, variables related to its development and its prognostic impact. We conducted a retrospective analysis of PAH patients who underwent a computed tomography or magnetic resonance.

Article Synopsis
  • The study looked at two different ways to treat patients with heart attacks using a technique called primary PCI, focusing on which artery should be treated first.
  • It found that both methods (ipsilateral and contralateral approaches) led to the same recovery times and results, but different approaches were preferred based on which artery was affected.
  • Overall, having more knowledge about a patient's heart can help doctors decide the best treatment plan, and the contralateral approach might be the better choice for many patients.
