Study summary

A single-center, open-label, exploratory randomized controlled study is proposed with the following objectives: whether prolonging the duration of anticoagulation to 12 months, compared with 6 months of routine anticoagulation, helps to reduce major adverse cardiovascular and cerebrovascular events in patients with left ventricular thrombosis and to reduce recurrence of thrombosis, as well as to assess their bleeding risk.

Patients with a definite diagnosis of left ventricular thrombus and age ≥18 years were included in cardiac ultrasound (including general ultrasound and sonography) and other examinations during hospitalization and outpatient visits. Exclusion criteria were detailed in the study protocol.

GROUPING: According to the duration of anticoagulation, they were divided into extended anticoagulation group (12 months) and conventional anticoagulation group (6 months).

INTERVENTION: This study is planned to extend the administration of rivaroxaban (Pulsatilla) 20 mg to 12 months in the experimental group. The conventional anticoagulation group will take the drug for 6 months Study Endpoints: The primary efficacy endpoint is a major cardiovascular-vascular adverse event at 1 year; the primary safety endpoint is bleeding of grade 3 or higher as defined by the BARC classification at 1 year.

Patient Follow-up Program: Subjects will require a total of 12 on-site follow-up visits (one per month) for safety evaluation, efficacy evaluation, medication adherence evaluation, and imaging follow-up at months 3, 6, and 12.

Inclusion criteria

①Patients who have been clearly diagnosed with left ventricular thrombus by inpatient or outpatient cardiac ultrasound (including general ultrasound and acoustic imaging).

②Age >= 18 years old

Exclusion criteria

Exclusion Criteria:

  • Patients do not agree to participate in the study or have poor compliance in the past

    • to anticoagulation or allergy to anticoagulants ③Have received oral anticoagulation after diagnosis of left ventricular thrombus.

      • Have undergone or are planning to undergo surgical procedures including left ventricular appendage thrombectomy, heart transplantation, ventricular wall tumor collapse, or valve replacement.

        • Presence of other long-term indications for anticoagulation, such as mechanical valve implantation, atrial fibrillation, etc.

          • Requirement for treatment with Tegretol and inability to change to clopidogrel bisulfate ⑦Presence of known malignant tumors, severe hepatic dysfunction ( classification B or less), severe renal dysfunction ( \<30ml/min), anemia ( \<100g/L), coagulation disorders and other underlying diseases, or \<3 years ⑧ Female patients are pregnant or breastfeeding ⑨ Patients with antiphospholipid syndrome
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Child-Pugh class

A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 18, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
