Transseptal puncture by CTP-2 method

Transseptal puncture by CTP-2 method: Results from cardiac computed tomography analysis and clinical application

The current used parameters for transseptal puncture (TSP) under fluoroscopic guidance is from left atriography and need to be verified by precise anatomic measurement. From February 2009 to July 2013, consecutive patients who received computed tomography (CT) were included. Landmarks and parameters were preliminary studied by right atriography, and further evaluated on the CT images of 1001 pa...

Thrombotic cardiac tamponade after transseptal puncture

An 84-year-old woman was admitted for catheter ablation of long-standing, permanent AF. Her previous medical history consisted of long-standing arterial hypertension and persistent AF diagnosed 3 years ago. She had undergone circumferential pulmonary vein (PV) isolation (ie, linear ablation around the PV antra with subsequent verification of PV isolation) and repeat ablation of a macroreentrant...

Percutaneous Approach, Including Transseptal and Apical Puncture

In contrast with the direct brachial technique (see Chapter 5), the percutaneous approach to left and right heart catheterization achieves vascular access by needle puncture , and thus obviates surgical isolation of the vessel during either the insertion or the subsequent withdrawal of the cardiac catheter. Once the needle has been positioned within the vessel lumen, a flexible guidewire is adv...

Left Ventricular Angiocardiography by Transseptal Puncture of the Left Atrium.

SELECTIVE angiocardiography of the left side of the heart is of prime importance for the accurate preoperative diagnosis of those lesions involving the mitral valve, ventricular septum, outflow tract of the left ventricle, or the aorta itself. The injection of contrast medium into the pulmonary artery for the demonstration of the left atrium and left ventricle is less satisfactory than the dire...
