Over the last 40 years, despite multiple advancements in percutaneous coronary interventions, calcified lesions remain a challenge for even the most experienced operators leading to an increase in...
Hemodynamic Support Devices
This hemodynamic support systems include intra-aortic balloon pumps (IABP), percutaneous ventricular assist devices (pVAD) like the Impella or tandemheart, and ventricular assist devices (VAD).

Figure 2: Angiography demonstrates a stenotic lesion in the mid right coronary artery, undilatable by standard high-pressure balloon angioplasty (inset, arrowheads). (B) Optical coherence tomography (OCT) cross-sectional (top) and longitudinal (bottom) images acquired before IVL and coregistered to the OCT lens (arrow in A) demonstrate severe near-circumferential calcification (double-headed arrow) in the area of the stenosis. (C) Angiography demonstrates improvement in the area of stenosis after IVL (inset; note the cavitation bubbles generated by IVL [black arrows]). (D) OCT cross-sectional (top) and longitudinal (bottom) images acquired post-IVL and coregistered to the OCT lens (white arrow in C) demonstrate multiple calcium fractures and large acute luminal gain. (E) Angiography demonstrates complete stent expansion with the semicompliant stent balloon (inset) without the need for high-pressure noncompliant balloon inflation. (F) OCT cross-sectional (top) and longitudinal (bottom) images acquired post-stenting and coregistered to the OCT lens (arrow in E) demonstrate further fracture displacement (arrow), with additional increase in the acute area gain (5.17 mm2), resulting in full stent expansion and minimal malapposition.

Two device technologies raised concerns in the industry based on recently released clinical data. The Cook Zilver PTX paclitaxel-eluting peripheral stent is among the devices included in a study questioning long-term safety of paclitaxel. The Abiomed Impella RP had higher than expected mortality in its post-approval study, possibly due to poor patient selection and implanting the device too late to aid the patient.

The Abiomed Impella RP had higher than expected mortality in its post-approval study, much higher than in its pre-market approval study. The vendor and the FDA believe this might be due to poor patient selection and implanting the device too late to aid the patient.

A pig heart, shown here, is very similar in size and anatomy to a human heart. For this reason, pigs are used extensively in pre-clinical animal testing for new implantable cardiovascular devices. If pig hearts could be used for human transplantation, it would greatly alleviate shortages of donor human hearts.
