Implantable Cardioverter-Defibrillator (ICD) Lead-Induced Septal and Left Ventricular Perforation in Hypertrophic Cardiomyopathy: A Case Report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Left ventricular (LV) perforation caused by an implantable cardioverter-defibrillator (ICD) lead is a rare but potentially fatal complication. We describe the case of a 34-year-old man with hypertrophic cardiomyopathy who underwent single-chamber ICD implantation for primary prevention of sudden cardiac death using an active-fixation transvenous lead positioned in the right ventricular septum. Four days after implantation, he developed acute chest pain, dyspnoea, hypotension, with clinical signs of evolving cardiac tamponade. Transthoracic echocardiography demonstrated a moderate circumferential pericardial effusion, while device interrogation revealed abnormal pacing parameters, prompting emergency pericardiocentesis with immediate haemodynamic stabilization. Computed tomography was subsequently performed to accurately delineate lead position and confirmed perforation through the interventricular septum with extension into the LV free wall, a finding that could not be fully characterized by echocardiography alone. The patient was transferred to a tertiary centre with continuous cardiac surgical support, where lead extraction and surgical repair of the myocardial defects were successfully performed using pledgeted sutures. The postoperative course was uneventful and follow-up imaging confirmed complete resolution of the pericardial effusion. Unlike the typical pattern of right ventricular free-wall perforation, this case involved transseptal migration of an ICD lead with left ventricular involvement, highlighting that hypertrophic myocardium does not preclude this life-threatening complication and underscoring the importance of early recognition and individualized management.
